Contact information is in the doc/FIM.TXT file, or in the bottom of this file. Please DO NOT dare sending bug reports about installation unless you have read the INSTALL file and you are sure all the dependencies on your system have been resolved. For example "[FIM] problems with resolution 457x3778" would be a good, informative subject for me. When submitting a bug report, please follow the following rules: - be as much informative as possible when describing your experience. - make a report about the current environment: ( make ; make report ) 2>&1 | gzip > fim.`date +%Y%m%d%H%M`.log.gz and send me the created .tgz file - please give me information about the exact way you experienced the problem - please give me information about the resolution/video mode you are working with; from the bash shell, execute the following and send me the output: ( for f in /sys/class/graphics/fb0/* ; do echo $f ; cat $f ; done ) - please send me the config.log file, too (especially if it is a build bug). it is of vital importance! (the config.log file is created by the configure script when you run the ./configure script) - if you are using an ad hoc method for installing (say, the ebuild for the Gentoo Linux ), consider sending the logfile created and named in the error messages. ==== CORE DEBUGGING Consider debugging with gdb or letting me do this for you! by running $ ulimit -S -c unlimited before Fim, in the case Fim should crash, it will generate a file called 'core'. That file, if sent to me (but contact me before sending, because it could be big!), will be helpful for debugging Fim and discover the causes of the crash. p.s.: please compile the code configuring in this way: ( use ./configure --help='-O0 -ggdb' ) and don't forget to send me the executable file, too :) ==== CONTACT You can mail your report to dezperado_FOobAr_autistici_Baz_org, by replacing _FOobAr_ with a '@' and _Baz_ with a '.'. ==== KNOWN BUGS 20150131 in aalib mode PageUp / PageDown do not seem to work. 20150123 When in framebuffer mode, never, for ANY reason, press C-z (^Z) with the intention of putting fim in the background. It will blind your console and allow only blind typing, which is a very dangerous situation! 20110603 Window splitting is disabled. ==== MINOR ISSUES 20091208 if fim is configured to take input from piped xfig (as xfig-3.2.5b), it could be - passively - subject to xfig's buffer overflow on files like: 0 1 2 3 4 1 2 3 4 5 6 7 ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ ( see http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=559274 and http://bugs.debian.org/cgi-bin/bugreport.cgi?msg=5;filename=xfig_poc.f;att=1;bug=559274) As long as xfig (fig2dev) is accessed through the popen() system call, there will be no harm to fim from xfig crash. 20091015 In 16 bit graphics mode, some lines which should be white actually look blue (seems not fim' fault; happens on both on ARM and x86) 20091013 fim -i < file.pdf # does not work 20091009 fim does not support 1,2,4 bit modes 20090328 problems with --std=c++98 in legacy src/FbiStuffJpeg.cpp code (now commented) 20070919 while command suffers from being not interruptible in some cases (when the image is small and not 'panable') 20070912 Debugging it with the framebuffer under gdb hangs the console (even with -p). 20070904 problems could occur with the commands giving output when no std::cout << "" is returned soon after (see Commandconsole.cpp mehods for this..) 20071128 tried: Linux host 2.6.19-gentoo-r5 #1 SMP Mon Sep 24 15:08:36 CEST 2007 ppc 7447A, altivec supported PowerBook5,4 GNU/Linux and gave problems with the PAGE_MASK macro, originally in /linux/include/asm-i386/page.h :) 20080504 Seems like running the aalib driver under screen maps -3072 units down the arrow keys. I do not see this problem in aalib under ssh. 20080127 Under screen, Fim behaves well but it doesn't handle well console switching: after a console switch, it doesn't redraw the image if not triggered to do so. 20080106 keys 'Insert,Cancel' are not recognized in the commandline mode. This issue will be fixed after the fbi core will be cleaned up and revised. 20070811 On CENTOS 64 bit, i reported linking problems : -ltermcap is required, too. I Don't know exactly how to fix this issue. 2007* Bugs shared with fbi, not fully solved: - do not switch console or interrupt the program while it is busy: it could hang your console and force you to make tricks to get back the terminal (like typing blindly through consoles, or trying to get to some X instance via ALT-F7-like sequences, or even restart the computer), and blind typing could be dangerous, if you do now know what you are doing! ==== OUTSTANDING FIXED ISSUES 20110602 fim versions before svn version r373 segfault in 32 bit framebuffer mode, on 64 bit builds ==== FIXED FBI/FBGS ORIGINATING BUGS Replaced popen with pipe calls : http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=422034, in rev. 213. Original typo in fbgsh : http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3119 fixed following the patch indicated on http://bugs.gentoo.org/show_bug.cgi?id=141684 : -gs -dSAVER -dNOPAUSE -dBATCH +gs -dSAFER -dNOPAUSE -dBATCH It could let a PostScript file execute evil code, according to the advisory. ==== UNFIXED EXTERNALLY ORIGINATING BUGS 20090329 On my debian box's aalib, the ASCII art driver leaks 224 bytes of memory. Actually, it happens the same when compiling aalib-1.4.0's aafire.c program against debian aalib and running it in console mode (no X). After clean aalib recompilation, these problems vanish. ==== SOLVED ISSUES 20110712 in sdl (x11) mode, when fim is spawned in a non-terminal environment, the readline mode does not work in the proper way. detecting this situation may be helpful to disable the readline mode at all in these cases, until a readline-centric fix is found.

(enabled by default) --enable-scripting Scripting. (enabled by default) --enable-output-console Output console. (enabled by default) --disable-as-text-rendering Disable as-text rendering (viewing of any file as character bytes -- not to be confused with the ASCII art output). --disable-raw-bits-rendering Disable raw bits rendering (viewing of any file as either a 1 or 24 bpp bitmap). --disable-loader-string-specification Disables the chance to specify a file loader. --enable-matrices-rendering Uses librsb for rendering of Matrix Market files (must have librsb-config in the PATH). Optional Packages: --with-PACKAGE[=ARG] use PACKAGE [ARG=yes] --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no) --with-regex Obsolete switch -- do not use this. (deprecated) --with-png-prefix=PFX prefix where libpng is installed (optional) --with-sdl-prefix=PFX prefix where libsdl is installed (optional) --with-cflags=CXXFLAGS Specify a custom CXXFLAGS append value. e.g.: -pg You cannot call this argument multiple times. In case you want completely reset CXXFLAGS use : CXXFLAGS='' ./configure .. Note that Fim is a C++ program, so we set CXXFLAGS=CXXFLAGS. --with-exec-shell=SHELL Specify alternate shell (ONLY if /bin/sh is broken) --with-default-consolefont=FILE Specify a default consolefont (psf or psf.gz format) file. --with-custom-hardcoded-consolefont=FILE Specify a custom consolefont to be hardcoded (uncompressed psf format, absolute path) at build time (requires --enable-hardcoded-font). --with-font-magnifying-factor=FACTOR If FACTOR>0, Will render text magnified by (hardcoded) FACTOR times. If FACTOR<=0, will allow run-time control of it via the _fbfont_magnify_factor variable. If negative, -FACTOR will be used as default. Default is 0 --with-tmpfile=FILE Specify where to put temporary files created when interacting with external conversion programs. Some influential environment variables: CC C compiler command CFLAGS C compiler flags LDFLAGS linker flags, e.g. -L if you have libraries in a nonstandard directory LIBS libraries to pass to the linker, e.g. -l CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I if you have headers in a nonstandard directory CPP C preprocessor YACC The `Yet Another Compiler Compiler' implementation to use. Defaults to the first program found out of: `bison -y', `byacc', `yacc'. YFLAGS The list of arguments that will be passed by default to $YACC. This script will default YFLAGS to the empty string to avoid a default value of `-d' given by some make applications. CXX C++ compiler command CXXFLAGS C++ compiler flags LIBTIFF libtiff library (contributes to LIBS) LIBGIF libgif library (contributes to LIBS) LIBJPEG libjpeg library (contributes to LIBS) LIBPS libspectre library (contributes to LIBS) LIBDJVU libdjvu libdjvulibre (contributes to LIBS) LIBPOPPLER poppler libdjvulibre (contributes to LIBS) CXXCPP C++ preprocessor PKG_CONFIG path to pkg-config utility PKG_CONFIG_PATH directories to add to pkg-config's search path PKG_CONFIG_LIBDIR path overriding pkg-config's built-in search path POPPLER_CFLAGS C compiler flags for POPPLER, overriding pkg-config POPPLER_LIBS linker flags for POPPLER, overriding pkg-config GLIB_CFLAGS C compiler flags for GLIB, overriding pkg-config GLIB_LIBS linker flags for GLIB, overriding pkg-config Use these variables to override the choices made by `configure' or to help it to find libraries and programs with nonstandard names/locations.

Here is a matrix of mmap possibilities: mmap private not fixed mmap private fixed at somewhere currently unmapped mmap private fixed at somewhere already mapped mmap shared not fixed mmap shared fixed at somewhere currently unmapped mmap shared fixed at somewhere already mapped For private mappings, we should verify that changes cannot be read() back from the file, nor mmap's back from the file at a different address. (There have been systems where private was not correctly implemented like the infamous i386 svr4.0, and systems where the VM page cache was not coherent with the file system buffer cache like early versions of FreeBSD and possibly contemporary NetBSD.) For shared mappings, we should conversely verify that changes get propagated back to all the places they're supposed to be. Grep wants private fixed already mapped.

Copying and distribution of this file, with or without modification, are permitted in any medium without royalty provided the copyright notice and this notice are preserved. This file is offered as-is, without warranty of any kind. Basic Installation ================== Briefly, the shell command './configure && make && make install' should configure, build, and install this package. The following more-detailed instructions are generic; see the 'README' file for instructions specific to this package. Some packages provide this 'INSTALL' file but do not implement all of the features documented below. The lack of an optional feature in a given package is not necessarily a bug. More recommendations for GNU packages can be found in *note Makefile Conventions: (standards)Makefile Conventions. The 'configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a 'Makefile' in each directory of the package. It may also create one or more '.h' files containing system-dependent definitions. Finally, it creates a shell script 'config.status' that you can run in the future to recreate the current configuration, and a file 'config.log' containing compiler output (useful mainly for debugging 'configure'). It can also use an optional file (typically called 'config.cache' and enabled with '--cache-file=config.cache' or simply '-C') that saves the results of its tests to speed up reconfiguring. Caching is disabled by default to prevent problems with accidental use of stale cache files. If you need to do unusual things to compile the package, please try to figure out how 'configure' could check whether to do them, and mail diffs or instructions to the address given in the 'README' so they can be considered for the next release. If you are using the cache, and at some point 'config.cache' contains results you don't want to keep, you may remove or edit it. The file 'configure.ac' (or 'configure.in') is used to create 'configure' by a program called 'autoconf'. You need 'configure.ac' if you want to change it or regenerate 'configure' using a newer version of 'autoconf'. The simplest way to compile this package is: 1. 'cd' to the directory containing the package's source code and type './configure' to configure the package for your system. Running 'configure' might take a while. While running, it prints some messages telling which features it is checking for. 2. Type 'make' to compile the package. 3. Optionally, type 'make check' to run any self-tests that come with the package, generally using the just-built uninstalled binaries. 4. Type 'make install' to install the programs and any data files and documentation. When installing into a prefix owned by root, it is recommended that the package be configured and built as a regular user, and only the 'make install' phase executed with root privileges. 5. Optionally, type 'make installcheck' to repeat any self-tests, but this time using the binaries in their final installed location. This target does not install anything. Running this target as a regular user, particularly if the prior 'make install' required root privileges, verifies that the installation completed correctly. 6. You can remove the program binaries and object files from the source code directory by typing 'make clean'. To also remove the files that 'configure' created (so you can compile the package for a different kind of computer), type 'make distclean'. There is also a 'make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. 7. Often, you can also type 'make uninstall' to remove the installed files again. In practice, not all packages have tested that uninstallation works correctly, even though it is required by the GNU Coding Standards. 8. Some packages, particularly those that use Automake, provide 'make distcheck', which can by used by developers to test that all other targets like 'make install' and 'make uninstall' work correctly. This target is generally not run by end users. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the 'configure' script does not know about. Run './configure --help' for details on some of the pertinent environment variables. You can give 'configure' initial values for configuration parameters by setting variables in the command line or in the environment. Here is an example: ./configure CC=c99 CFLAGS=-g LIBS=-lposix *Note Defining Variables::, for more details. Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you can use GNU 'make'. 'cd' to the directory where you want the object files and executables to go and run the 'configure' script. 'configure' automatically checks for the source code in the directory that 'configure' is in and in '..'. This is known as a "VPATH" build. With a non-GNU 'make', it is safer to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use 'make distclean' before reconfiguring for another architecture. On MacOS X 10.5 and later systems, you can create libraries and executables that work on multiple system types--known as "fat" or "universal" binaries--by specifying multiple '-arch' options to the compiler but only a single '-arch' option to the preprocessor. Like this: ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CPP="gcc -E" CXXCPP="g++ -E" This is not guaranteed to produce working output in all cases, you may have to build one architecture at a time and combine the results using the 'lipo' tool if you have problems. Installation Names ================== By default, 'make install' installs the package's commands under '/usr/local/bin', include files under '/usr/local/include', etc. You can specify an installation prefix other than '/usr/local' by giving 'configure' the option '--prefix=PREFIX', where PREFIX must be an absolute file name. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you pass the option '--exec-prefix=PREFIX' to 'configure', the package uses PREFIX as the prefix for installing programs and libraries. Documentation and other data files still use the regular prefix. In addition, if you use an unusual directory layout you can give options like '--bindir=DIR' to specify different values for particular kinds of files. Run 'configure --help' for a list of the directories you can set and what kinds of files go in them. In general, the default for these options is expressed in terms of '${prefix}', so that specifying just '--prefix' will affect all of the other directory specifications that were not explicitly provided. The most portable way to affect installation locations is to pass the correct locations to 'configure'; however, many packages provide one or both of the following shortcuts of passing variable assignments to the 'make install' command line to change installation locations without having to reconfigure or recompile. The first method involves providing an override variable for each affected directory. For example, 'make install prefix=/alternate/directory' will choose an alternate location for all directory configuration variables that were expressed in terms of '${prefix}'. Any directories that were specified during 'configure', but not in terms of '${prefix}', must each be overridden at install time for the entire installation to be relocated. The approach of makefile variable overrides for each directory variable is required by the GNU Coding Standards, and ideally causes no recompilation. However, some platforms have known limitations with the semantics of shared libraries that end up requiring recompilation when using this method, particularly noticeable in packages that use GNU Libtool. The second method involves providing the 'DESTDIR' variable. For example, 'make install DESTDIR=/alternate/directory' will prepend '/alternate/directory' before all installation names. The approach of 'DESTDIR' overrides is not required by the GNU Coding Standards, and does not work on platforms that have drive letters. On the other hand, it does better at avoiding recompilation issues, and works well even when some directory options were not specified in terms of '${prefix}' at 'configure' time. Optional Features ================= If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving 'configure' the option '--program-prefix=PREFIX' or '--program-suffix=SUFFIX'. Some packages pay attention to '--enable-FEATURE' options to 'configure', where FEATURE indicates an optional part of the package. They may also pay attention to '--with-PACKAGE' options, where PACKAGE is something like 'gnu-as' or 'x' (for the X Window System). The 'README' should mention any '--enable-' and '--with-' options that the package recognizes. For packages that use the X Window System, 'configure' can usually find the X include and library files automatically, but if it doesn't, you can use the 'configure' options '--x-includes=DIR' and '--x-libraries=DIR' to specify their locations. Some packages offer the ability to configure how verbose the execution of 'make' will be. For these packages, running './configure --enable-silent-rules' sets the default to minimal output, which can be overridden with 'make V=1'; while running './configure --disable-silent-rules' sets the default to verbose, which can be overridden with 'make V=0'. Particular systems ================== On HP-UX, the default C compiler is not ANSI C compatible. If GNU CC is not installed, it is recommended to use the following options in order to use an ANSI C compiler: ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" and if that doesn't work, install pre-built binaries of GCC for HP-UX. HP-UX 'make' updates targets which have the same time stamps as their prerequisites, which makes it generally unusable when shipped generated files such as 'configure' are involved. Use GNU 'make' instead. On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot parse its '' header file. The option '-nodtk' can be used as a workaround. If GNU CC is not installed, it is therefore recommended to try ./configure CC="cc" and if that doesn't work, try ./configure CC="cc -nodtk" On Solaris, don't put '/usr/ucb' early in your 'PATH'. This directory contains several dysfunctional programs; working variants of these programs are available in '/usr/bin'. So, if you need '/usr/ucb' in your 'PATH', put it _after_ '/usr/bin'. On Haiku, software installed for all users goes in '/boot/common', not '/usr/local'. It is recommended to use the following options: ./configure --prefix=/boot/common Specifying the System Type ========================== There may be some features 'configure' cannot figure out automatically, but needs to determine by the type of machine the package will run on. Usually, assuming the package is built to be run on the _same_ architectures, 'configure' can figure that out, but if it prints a message saying it cannot guess the machine type, give it the '--build=TYPE' option. TYPE can either be a short name for the system type, such as 'sun4', or a canonical name which has the form: CPU-COMPANY-SYSTEM where SYSTEM can have one of these forms: OS KERNEL-OS See the file 'config.sub' for the possible values of each field. If 'config.sub' isn't included in this package, then this package doesn't need to know the machine type. If you are _building_ compiler tools for cross-compiling, you should use the option '--target=TYPE' to select the type of system they will produce code for. If you want to _use_ a cross compiler, that generates code for a platform different from the build platform, you should specify the "host" platform (i.e., that on which the generated programs will eventually be run) with '--host=TYPE'. Sharing Defaults ================ If you want to set default values for 'configure' scripts to share, you can create a site shell script called 'config.site' that gives default values for variables like 'CC', 'cache_file', and 'prefix'. 'configure' looks for 'PREFIX/share/config.site' if it exists, then 'PREFIX/etc/config.site' if it exists. Or, you can set the 'CONFIG_SITE' environment variable to the location of the site script. A warning: not all 'configure' scripts look for a site script. Defining Variables ================== Variables not defined in a site shell script can be set in the environment passed to 'configure'. However, some packages may run configure again during the build, and the customized values of these variables may be lost. In order to avoid this problem, you should set them in the 'configure' command line, using 'VAR=value'. For example: ./configure CC=/usr/local2/bin/gcc causes the specified 'gcc' to be used as the C compiler (unless it is overridden in the site shell script). Unfortunately, this technique does not work for 'CONFIG_SHELL' due to an Autoconf limitation. Until the limitation is lifted, you can use this workaround: CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash 'configure' Invocation ====================== 'configure' recognizes the following options to control how it operates. '--help' '-h' Print a summary of all of the options to 'configure', and exit. '--help=short' '--help=recursive' Print a summary of the options unique to this package's 'configure', and exit. The 'short' variant lists options used only in the top level, while the 'recursive' variant lists options also present in any nested packages. '--version' '-V' Print the version of Autoconf used to generate the 'configure' script, and exit. '--cache-file=FILE' Enable the cache: use and save the results of the tests in FILE, traditionally 'config.cache'. FILE defaults to '/dev/null' to disable caching. '--config-cache' '-C' Alias for '--cache-file=config.cache'. '--quiet' '--silent' '-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to '/dev/null' (any error messages will still be shown). '--srcdir=DIR' Look for the package's source code in directory DIR. Usually 'configure' can determine that directory automatically. '--prefix=DIR' Use DIR as the installation prefix. *note Installation Names:: for more details, including other options available for fine-tuning the installation locations.

Version 0.6-rc0 A summary of major improvements: * Colour ASCII-Art output via libcaca, selected with -o ca * better mechanism to determine best output device * font magnification by integer factors, good for higher resolutions * runtime font selection * new options to commands "scale", "goto", "limit", "list", ... * 'limit' view to relevant image files based on properties (like in 'mutt') * pass key presses to be automated at startup with -k and -K options * pretty free from memory leaks * -X switch inhibits custom external converters * new powerful subcommand "list 'mark'" * new command-line switches (--sort..) to sort the initial files list * use mipmaps for faster scaling * open files from a files list with -L * load image description files with -D * background recursive scan and load of files with -B * search files at startup based on description with -/ and --// * new verbosity and debug options * better error handling when encountering corrupt files * fast in-place switch to high-res file via --load-shadow-directory * improvements in -o aa (Ascii Art output device with aalib) * more options for window size selection in -o sdl * Keys F1,F2,F3,F4,F5,F6,F7,F8,F9,F10,F11,F12 now usable with 'bind' In detail, in no particular order: * Experimental support for SDL2. * More responsive readline mode. * Switch --resolution 'fullscreen' appends 'W' if in SDL mode. * If a "matrix market" file is loaded, its rows, columns and nnz are image variables, too. * Introduce special 'early' form -C =var=val where variable var is assigned to unquoted and non-interpreted value val immediately. * Fix: --cd-and-readdir was not jumping back to first file. * Fix: --device option not ignored anymore. * Rename --no-etc-rc-file switch to --no-etc-fimrc-file . * fimgs: bunzip2, wget, and xz are now optional. * Bugfix: fimgs to properly remove temporary directory after loading downloaded files. * Misc small improvements in documentation text output and reporting (no cursor in post-search output line; misc messages). * Key 'Z' now assigned to 'sleep 1'. * Key 'Del' now assigned to 'list "remove"'. * Add -= as short form of the --no-auto-scale option. * Experimental: add command "crop", also activated after selecting the area by holding Shift and clicking with left mouse button (if running with -o sdl). * Add command "pan 'vsteps%' 'hsteps%'" and "'pan 'vsteps' 'hsteps'". * Keys F1,F2,F3,F4,F5,F6,F7,F8,F9,F10,F11,F12 are now usable with 'bind' with modes -o aa, -o ca, -o dumb. * Fix for -o sdl: when flipped or mirrored, it used to draw a smaller box by mistake. * Only filenames matching "^[/A-Za-z0-9_.][/A-Za-z0-9_.-]*$" can occur in a conversion command involving an external program. * --pread-cmd=command substitutes any occurrence of '{}' in command with the actual filename, executes the result and reads an image from its stdout. * -o fb=S will not tolerate running under screen. * Bugfix in --script-from-stdin now prevents possible crashes. * Removed configure options --enable-c++11 -- use CXXFLAGS instead. * Bugfix: 'autocmd_del' with no arguments would crash. * Bugfix: autocommand "PostHardcodedConfigLoading" now triggers even if --disable-fimrc . * Internals: considerably expanded 'make tests'. * Add command 'stderr', similar to 'stdout'. * This is the last FIM version supporting the C++03 standard. * Refresh configure and Makefile templates. * Build fixes for the MinGW environment. * man fim: improve manual contents (on ~/.fim_history, individual options, wording, etc.). * man fimrc: added a section with default aliases, * Where appropriate, 'make tests' uses 'timeout' to prevent possible hangs. * Switch -K aka --chars-press simulates input of characters at startup. * Fix: slideshow function (e.g. `fim --slideshow=5 media/`) will now cycle forever, unless --once/-1 option specified (as in fbi). * Fix: after 'quit' no command shall execute anymore (unless in -F). * With SDL one can specify window size as percentage of allowed size (-o sdl=w55%), or draw a help grid map (-o sdl=h). * With SDL (-o sdl), center window by default. * Fix: now pressing keys "1n1n" will not execute 'n' 11 times, but twice. * configure --enable-debug is a developer option now. * libcaca (-o ca) mode is now complete and is the default ASCII Art mode. * Slideshow function (e.g `fim --slideshow=5 *.jpg`) now more responsive. * Arrow keys are now working in aalib (-o aa). * Bugfix with aalib (-o aa): don't truncate long lines. * Avoid memory leak in language parser. * Avoid console buffer memory corruption. * Eliminate a memory leak from file loading code. * Eliminate memory leaks in PNG, JPG, TIFF, EXIF, and font decoding code. * Fix possibly broken `make -j` in rebuilding fimgs.man and fimrc.man. * Correct configure script check for regcomp() -- could lead to false negatives. * Don't break build on missing 'gs'. * Experimental: use --load-shadow-directory to add a "shadow directory". Then 'scale "shadow"' (bound to key '"') will substitute the current displayed image with that of the first same-named file located under a shadow directory. * When loading a directory, regular expression from default "_pushdir_re" variable now matches filenames with .webp extension. * Fix: `fim -c '/'` was broken. * Add " INTEGER , INTEGER IDENTIFIER arguments" syntax to repeat a command on each file in the interval and substitute its name to '{}' in the arguments to an iterated command IDENTIFIER. * If a key is bound to e.g. 'goto "+1F"', keep pressing it to accelerate (not if e.g. "+1f"). * Internal fix: piping from external commands was using 0 instead of 'WNOHANG', leading to hanging. * Internal fix: error handling was missing. * fimgs now to handle tar.xz archives. * Reload automatically image on file change. * Command 'list' 'sort_var' 'var' to sort file list according to values of 'i:var'. * Command 'list' 'sort_comment' to sort file list according to 'i:_comment' value. * Add a --verbose-font-load switch to set '_fbfont_verbosity=1'. * Variable '_fbfont_verbosity' sets verbose font loading. * Fix: short options -b, -h, -R were not getting optional argument (e.g. -b1). * Key combination C-r now assigned to "reload ''". * Fix: symbol from fbi sources clashed with gcc-6 onwards, breaking compilation. * Key combination C-w assigned to setting auto-scaling to width. * Smoother scroll of large images. * If SSH_TTY set and no output device specified, give precedence to aalib, then libcaca. * Bugfix: in --as-text will avoid repeated reload of file. * Hardcoded font (if configured in) will serve as fallback font. * Add a --no-pipe-load / -X switch to _no_external_loader_programs=1; * Description variables beginning with '_' will not go into i: . * List variables in all i:* read from description file with "list 'vars|variables'". * Expansion of @variables and @# comments from description files. * The menu key in SDL mode shows a temporary mouse click actions menu. * Bugfix: description file reading was crashing due to wrong check. * Caption text of "_caption_over_image" takes at most half of the screen. * If _caption_over_image=3, image is possibly drawn below the caption. * The 'v' and 'S' keys now cause a redraw. * The description line can be of any length. * New configure option, defaulting to: --enable-paths-in-man; it generates man pages with configure specified paths (e.g. sysconfdir, docdir). * Fix: -s switch was broken. * Add a semicolon (;) to -C arguments if not present already. * Framebuffer console switch off while loading: configure with the --enable-framebuffer-switch-while-loading switch to have it back. * Fix: configure would fail on --disable-aa and absent aalib. * Now configure has --enable-seek-magic by default. And is more verbose. * Command 'help' also shows key bindings, and give multiple answers if matching. * For each word following switch --help, an individual help message is shown. * Command 'goto' accepts multiple arguments; evaluating them until the first one triggering a jump. * Command goto {'-/'|'+/'}[C] jumps to a file based on character C (default 'S'). If C is 's', to prev/next file with same directory name. If C is 'd', to prev/next file with directory name down the same hierarchy. If C is 'u', to prev/next file with directory name up the same hierarchy. If C is 'b', to prev/next file with same basename. If C is as above but uppercase, to the prev/next file not matching the criteria. * Accordingly, aliases 'next_file_dir_same', 'next_file_dir_other', 'next_file_dir_up', 'next_file_dir_down', 'next_file_same_basename', 'prev_file_dir_same', 'prev_file_dir_other', 'prev_file_dir_up' 'prev_file_dir_down' 'prev_file_same_basename'. * Fix: 'recording' command was not functioning properly. * Fix: don't pop back last command if "recording 'stop'" executed outside of recording mode. * Fix: won't clear recorded list if calling recording 'start' multiple times. * Specifying more than once any of -p -i - causes a warning. * New switch --verbose-interpreter to execute interpreter verbosely by setting adequately _debug_commands='ackC'. * Strings specified within single quotes have single quotes escaped, just as double quotes. So that e.g.: '\'hello\'' equals "'hello'" and "\"hello\"" equals '"hello"'. * Variable '_debug_commands' is now a string with several verbosity options. * Fix: misc fixes for --offset, e.g. avoiding probing for external loader programs. * Add --verbose-load option for verbose file loading. * -C '_seek_magic=..' probes whole range of specified signature when loading a file. * Fix in _seek_magic documentation. * Option --offset accepts numbers suffixed by one of K, M, and G for respectively kibi-, mebi-, and gibi- (2^10, 2^20 and 2^30) units. * Bugfix: --offset option was ignoring lower bytes-offset. * Fix: a check was missing in the PS decoder when reading from stdin. * Command 'pan' accepts '-' and '+' to jump to prev/next file if border is reached. * Command 'font' controls displayed font and scans font directories. * Keys '{' and '}' cycle through available consolefonts. * Variable _fbfont_magnify_factor scales text font at runtime. * Variable _fbfont_as_screen_fraction; if >0, font is scaled to exceed 1/_fbfont_as_screen_fraction of both width and height. If _fbfont_as_screen_fraction<0, font scaling is fixed. * Keys '[' and ']' bound to new aliases "font_reduce" and "font_magnify". * Key '|' bound to new alias "toggle_font_auto_scale". * Switch -r {width:height} / --resolution {width:height} behaves as expected in SDL mode. * Variable _downscale_huge_at_load, if 1 (default), downscale automatically huge images at load time. To avoid loading images exceeding too much screen size. * Variable i:_buffered_in_tmpfile stores temporary decoding image filename, if any. * Internally load SVG files by invoking inkscape --without-gui --export-png . A file beginning with "1; 1/16 if 1, no tolerance if <1. * Variable "_want_wm_mouse_ctrl" controls mouse click/movement behaviour in SDL mode. * Variable "_min_cached_images" is the minimum number of images to keep from eviction. * Commands scale '<' / scale '>' shrinks/magnifies the image using cached mipmaps. * By default, show mouse cursor in full screen SDL mode. * Autocommand "PostInteractiveCommand" does not trigger anymore after 'quit' command. * In case of a CBZ,CBR,PDF,PS,DVI file, the fimgs script now uses '--autotop --autowidth'. * The fimgs script now probes for unrar-nonfree/rar/unrar-free (in this order). * Customize overlay text via variable '_caption_over_image_fmt'. * Command syntax 'goto {+|-}identifier[+]' (new) jumps to next file having a different value of i:identifier, also empty if without trailing `+'. * Command "limit '-set_union'" merges current limited list with the new one. * Command "limit '-merge'" merges current limited list with the new one. * Command "desc 'reload'" loads once again description files specified at the command line with --load-image-descriptions-file. * FIM only checks for filename duplicates if a sorting option is specified. * Switch -P/--text-reading fixed. Seems to be broken in version 0.5. * Command "color": "color 'negate'" and "color 'desaturate'" introduced. * Commands 'negate' and 'desaturate' deleted. * Command "color CVS" (CVS among 'protanopia', 'deuteranopia', 'tritanopia', 'p', 'd', 't') simulates a color vision deficiency; adding 'daltonize' applies a tentative color correction; "color 'colorblind'" is short for "color 'deuteranopia'". * Command "color 'identity'": populate the image with 'RGB identity' pixels. * Introduce a "#!fim:/=dir" special description line to specify directory prepended to basename. * Introduce a "#!fim:\=dir" special description line to specify directory prepended to filepath. * Command limit '-list' lists existing variables identifiers as set via 'desc' * Command limit '-list' 'id' lists existing values for instances of variable 'id' as set via 'desc' * Command "limit '~i' MINIDX[-MAXIDX]", with MINIDX and MAXIDX numbers (possibly with K as x 1000 multiplier) restricts filenames list to the specified interval. * Command "limit '~d'", limits to files having exact current file's modify date +- one day. * Command "limit '~z'" limits to files having same file size as the current. * Command "limit '~z' MINSIZE[-MAXSIZE]", with MINSIZE and MAXSIZE numbers with possibly K (x 1024) or M (x 1024 1024) multipliers, limits according to file size. * Command "limit '~d' MINTIME[-MAXTIME]", with MINTIME and MAXTIME numbers, limits files list according to file modify date (expressed as seconds since the epoch, see 'man 2 time'). * Command "limit '~d' MINDATE[-MINDATE]", with MINDATE and MAXDATE dates as in DD/MM/YYYY, and after 1900. * Command "limit '-further' ..." makes 'limit' act on the current list, rather than on the full anew. * Command "limit" uses new criteria: If invoked with '~!' it restricts to files with unique basename. If with '~=', to files with duplicate basename; if with '~^', to the first of the files with duplicate basename; if with '~$', to the last of the files with duplicate basename. * Alias "unlimit" resets the limited list. * Add variable '_all_file_loaders': a space-separated list of hardcoded file loaders usable with '_file_loader'. * Switch -R/--recursive[=arg] has now an optional argument; overwrites (if set) or appends to (if beginning with + or |) the "_pushdir_re" variable (recursed filename extensions). * Introduce a "#!fim:+=" special description line to append to cached description. * Introduce a "#!fim:^=" special description line to prepend to cached description. * Introduce a "#!fim:!=" special description line to reset all variables of the cached namespace. * Command 'desc "save"' functionality to save descriptions file data from the currently browsable images list. * Command 'desc "-append" "save"' works in append mode. * Command 'desc "-all" "save"' saves also all descriptions file variables. * Command 'desc "-nooverw" "save"' does not force overwrite. * To ease reproducible builds: imposing LC_ALL=C to $(YACC) and $(SORT), vim2html.pl reads SOURCE_DATE_EPOCH * New switch --mark-from-image-descriptions-file: read file names from a description file and use them to mark current list files. * Introduced alphanumeric restriction in the descriptions shebang variables: must begin with underscore or alphabetic, continue with underscore or alphanumeric. * Keys '(' and ')' are now bound respectively to "goto '^p'" and "goto '$p'"; that is jump to first or last page. * Available symkeys are now documented in a section of man fimrc. * Switch -k --keysym-press to simulate press of keysym at startup. Keysym can be prefixed by a repetition count number. * New switch -/ as short form of of -c /. * New switch --// as short form of of -c / with _re_search_opts='f'. * Tehe space key (' ') is now assigned to 'scrollforward' (earlier was 's'). * Introduced context prepend/append shebang syntax "#!fim:^=" and "#!fim:+=" in description files. * Switch --read-from-stdin-elds supports now the ASCII NUL terminator (via ''). * Switch -V (--version) prints to stdout (not anymore to stderr). * The -B switch is now shorthand for --background-recursive. * If compiled in pre-C++11 flags, -B / --background-recursive behaves as -R. * Switch -S is now short form of --image-descriptions-file-separator (not anymore for --sanity-check). * Switch -D is now short form of --load-image-descriptions-file (not anymore for --dump-default-fimrc). * Switch -L/--read-from-file: read an image list from file (similarly to the - switch). * Now caching of mipmaps is on by default; can be turned off with new variable '_cache_control'. * Variable "_push_pushes_dirs"; if it is 2, also push hidden files and directories; that is, ones whose names begin with a dot (.). * configure --with-font-magnifying-factor=FACTOR controls text magnification by an integer factor. If FACTOR is positive, this value is hardcoded and cannot be changed at runtime. If FACTOR is negative, -FACTOR is default, but can be changed at runtime. If FACTOR is 0 (default) a default of 1 applies, and can be changed at runtime. This option is meant to be used on configurations with high resolutions and small consolefonts. * configure --with-tmpfile specifies a new temporary directory. * configure tries to detect curses/ncurses. * Fix: mouse movement under SDL used to trigger unnecessary screen redraws. * Fix: the last used image is to be evicted from the cache as last, after possibly prefetched images. * Fix: in configure script, the regex_t check was unnecessarily broken. * Fix: ./configure --disable-pcx was not properly disabling PCX format support * With C++11 flags, --background-recursive loads images in the background recursively (experimental, unfinished). * Use variable "i:_file_load_time" to store the time taken to load the file and decode the image. * Use variable "_use_mipmaps=2" to compute the mipmaps faster, using every fourth source pixel. This can be a good solution for speeding up large photographs scaling. * Description files beginning with "#!fim:desc" (of whatever extension) can now be loaded as they were normal image files. * Add switch --reverse to reverse the file list. * Add switch --sort-mtime to sort file list according to modification time. * Add switch --sort-fsize to sort file list according to file size. * Command "list 'sort_mtime'" to sort file list according to modification time. * Command "list 'sort_fsize'" to sort file list according to file size. * Command "list 'mark' {args}" accepts now exactly what "limit {args}" does. * Command syntax 'list "markall"' introduced. * Command syntax 'list "dumpmarked"' and 'list "unmarkall"' introduced. * Command 'list "swap"' introduced. * New '_lastgotodirection' variable, with the last file goto direction. * Key 'Enter' now marks and goes forward or back according to variable '_lastgotodirection'. * Fix: the largest mipmap was not always being used. * Fix: -lfl linkage is not really necessary: removed it. * Fix: support for PPM files with 2 bytes per sample. * Fix: a few more checks when reading PCX files. * Fix: documented that switch --sanity-check terminates the program, rather than continuing. * Fix: when stdint.h is available use uint8_t, uint16_t, uint32_t instead of non-portable __u8, __u16, __u32 * Fix: compilation was broken without framebuffer (FIM_WITH_NO_FRAMEBUFFER) * Fix: cleaned up the internal keysyms initialization code. * Fix: removed obsolete documentation for the "window" command, now disabled. * Bugfix: improve GIF error handling. * Bugfix: on certain framebuffer configurations part of the screen was not being redrawn. * Bugfix: conversion from external program was vulnerable to failure due to a missing check. * Bugfix: avoiding data corruption when handling %k expando. * Bugfix: repeating "recording 'repeat_last'" (default '.' key) by prepending a number now works. * Fix: configure uses `sdl-config --static-lib`. Version 0.5 * -R / --recursive switch to turn on recursive push of command line specified directories * added --sort and --sort-basename to sort the images list * introduced mipmap mechanism (_use_mipmaps) for faster display/scaling of images * status bar customizable with _display_status_fmt and _info_fmt_str, which can be controlled by the use of special image variable specifiers ('expandos'): "%T" expando to get (and display) total memory used by the program "%C" expando to get (and display) file/memory usage by image cache "%M" expando to get (and display) memory used by the current (displayed) image "%c" expando to get (and display) centering information "%m" expando to get (and display) current image mipmap occupation information "%k" expando to get (and display) current image i:_comment value "%?PRE?VAR?POST?" expando to get (and display) "PRE".i:VAR."POST" ... * search (and jump) on image descriptions via 'goto' and key '/' * when repeating search with 'repeat_last', will use last direction * '?' key is now assigned to backward search (goto '-//') * default 'C-p' key is now assigned to repeat last backward search (goto '-//') * image cache will remember alignment within viewport * jump back and forth from the last viewed image with the ' (single quote aka apostrophe) key and the _lastfileindex variable * added --load-image-descriptions-file (equivalent to 'desc' 'load') to populate the i:_comment values of each loaded image file and set _caption_over_image=2 (with it added also --image-descriptions-file-separator) * added the 'desc "load"' command to load a textual files comments description file * introduced a 'limit' command, with comment, file name, or marked file criteria * the '`' key is bound to toggle limit'ing to the marked files list * introduced 'list "mark"' and 'list "unmark"' subcommands styled as 'limit' * load i:_comment and i:var from description file, with forms: "filename comment" (to i:_comment), "#!fim:var=value" (to set i:var=value on all all the files following) "#!fim:var=" (to unset i:var=value on all all the files following) "filename #!fim:=" (to i:_comment from the value read last) "filename #!fim:+comment" (similar, but will append the new comment) "filename #!fim:^comment" (similar, but will prepend the new comment) "filename #!fim:s/f/t" (similar, but replace string f with string t) * EXIF tags will be read with libexif and become i:EXIF_-prefixed variables * if _want_exif_orientation is set, images will be reoriented according to EXIF metadata (i:__exif_orientation, i:__exif_mirrored, i:__exif_flipped). * the 'help' command will search also in fim command options * will optionally use C++11 constructs with ./configure --enable-cxx11 (no user level impact) * scaling image code faster (thanks to __restrict__ pointers) * customizable SDL window caption line with _want_wm_caption_status * BMP format support is now optional * PCX format support (optional) * changed meaning of variable _ignorecase: now it affects autocommands * introduced variable _re_search_opts affecting regexp-based search * default key 'r' is bound to 'rotate90', key 'R' to 'rotate270' * can be invoked without stdin; e.g. from an X menu * added "display 'resize'" to resize the SDL window, optionally to the image size * default SDL mode is windowed now * by default, the 'C-w' key will resize the SDL window to the original image size * by default, the 'W' key will resize the SDL window to the image size, and added an --autowindow switch to adapt window size to picture size * the 'help' command will search in help items if argument starts with / * special variable i:* expanding to all the variable name/value pairs of the current image * opening image files in archives (e.g. CBZ,CBR,RAR,TAR,TGZ,TBZ,7Z,ISO,...) with libarchive (experimental) * JPEG-2000 file support via JasPer (experimental) * added a ':- INTEGER' syntax, so one can specify the file in the list counting from the end * added an _archive_files variable to specify which file name types specify archives * added a 'list "pushdirr"' command, working like "pushdir" but recursively * the _fbfont variable will contain the current console font file string * mirror/flip are now being applied with respect to the viewport borders * stat() checking of files on load can be disabled with _push_checks * added --no-stat-push to set _push_checks=0 before initialization * added the _caption_over_image variable (which is 0 unless --load-image-descriptions-file) * 'Pause' and 'Menu' keys are now available in SDL (-o sdl) mode * added 'list' 'marked' to show the list of marked files * key 'Del' bound to pop (delete) the current image from the list * i:_file loader will store the used loader string * switch --offset accepts a range now (using the new _open_offset_retry variable) * if an image has been opened with an offset, i:_open_offset will be set accordingly * variable i:pagecount is now replaced by i:pages * put aside (disabled) the v: b: and w: namespaces until they make more sense * panning on mouse movement in SDL mode * `make fim' goal has been deleted * changed librsb library detection: now it's e.g.: LIBS="`librsb-config --ldflags --extra_libs` " CXXFLAGS="`librsb-config --cflags` "\ ./configure --enable-matrices-rendering * bugfix: in some situations fim -o fb was not clearing the screen before drawing the image * bugfix in the "list 'remove'" internals * --binary=1/--binary=24 will not pad tiny renderings to _preferred_rendering_width pixels * fix: corrected the quiet mode (-q) to be quieter * fix: no zlib.h build time dependency (this will be reintroduced in the future) Version 0.4 * changed --random semantics and introduced --random-no-seed switch * customizable status bar file info string * introduced --as-text to render printable bytes as text * key r is bound to 'rotate90', key R to 'rotate270' * bug fixes for the g: namespace, SDL/X mode, "list 'pop'" command, the --offset option, 'ascale' and rotation, documentation.

development. If you are interested into Fim internals, philosophy, or get some inspiration, you are welcome to give a look here. You can propose ideas to the fim-devel mailing list: fbi-improved-devel@nongnu.org Warning : This file is outdated; actual development notes are taken elsewhere. ------------------------------------------------------------------------------- Misc Current development directions 20141130 disabling convert or bmp can break test8 -- shall fix this, perhaps by ignoring the *.svg file there. 20141130 shall support a dual configure style: for each $LIBRARY, $FIM_LIBRARY_LIBS/$FIM_LIBRARY_CXXFLAGS and LIBS/CXXFLAGS. 20141130 rename configure options w.r.t. program options; e.g. --raw-bits-rendering to -o bit1/ -o bit24 20141130 configure output shall fit in one screen 20141129 the configure is not well made w.r.t. exif, jasper, ... 20141129 setGlobalVariable -> setGV 20141129 setGlobalVariable("i:",FIM_VID_WANT_AUTOCENTER,1); 20141123 clean up Image::getInfo 20141122 document/expand the FIM_WANT_EXPERIMENTAL_BASENAME functionality. 20140830 need a precise control of scaling rules and viewports cache, as well to extend the viewport cache to scaled images 20131107 fix --disable-scripting case ! 20131107 this is spurious: fim::string execute(const std::vector &args) 20131107 getIntVariable(varname) -> getIntVariable(varname, domain) 20131010 text/ascii/bits ascii renderer as funny fallback renderers 20131010 shall configure default tmpdir to /dev/shmem/something 20131009 may interface to http://www.feep.net/libtar/ 20130902 add a simple menu e.g.: using Motif (http://www.opengroup.org/desktop/motif.html), or buttons; e.g.: using X: http://www.x.org/releases/X11R7.7/doc/libX11/libX11/libX11.html#XEvent 20130829 interface to a library for gestures, someday. 20130824 need a "verbose pressed keys" mode, to help when guessing key bindings. 20130725 shall add autodetection of file format to "fim -" 20130702 "nextindir" function 20130702 http://dvdhrm.wordpress.com/2012/12/10/kmscon-introduction/ 20130620 need a minimal ppm file for testing 20130523 fix the bug when loading say, a a/1.fake and getting the files list shortened by two instead of one. 20130505 glob() on non existent files 20130412 may use a library like http://www.littlecms.com/ 20120811 need proper jpeg error handling 20120805 feeding a .png named PS file can lead to segfault. why ? 20120804 should create a general 'filter' autocmd trigger 20120804 negate and desaturate should be either applied instantly or accumulated in queue as transformations 20120718 " - multiple internal windows with indipendent images displayed at once" is discontinued! 20120705 some day would be nice to use dnotify 20120407 to clone a whole fim instance in a new process 20120130 to open svg files "natively" 20120129 for scalings that are multiples of an integer, may write a specific code 20120108 use zzuf; e.g.: for ((seed=0;seed<4;++seed));do zzuf -I jpg -s $seed src/fim media/ -c quit ; done 20111202 seem like an empty eps file crashes fim 20111122 fim inverts the colours of eps files 20111112 font resources: psf tools: http://www.seasip.info/Unix/PSF sigma consolefont: http://homepage.ntlworld.com/zarniwhoop/consolefonts/sigma.html an old kbd HOWTO http://www.win.tue.nl/~aeb/linux/kbd/font-formats-1.html psf format specs: http://tph16.tuwien.ac.at/cgi-bin/dwww/usr/share/doc/console-tools/file-formats/psf an ancient article about linux 2.4 font handling: http://linuxgazette.net/issue91/loozzr.html a bibliography (loosely related to psf): http://fontforge.sourceforge.net/bibliography.html 20111111 may use libgunzip / gzip decoding library ? 20111107 what about uploading nightly versions to savannah ? shall upload fim to savannah ! 20111025 seems like putting an invalid entry in the fonts list breaks list scanning 20111016 in the cookbook: how to 'catch' images in a directory full of oddly named files ? 20111008 decouple strings location from executable (e.g.: allow for a memory-mapped help/strings file) 20111005 imlib2 shall be suggested among devices on device fail. on hlst3, 'w' rendering bug. screen-patch should be optional at runtime when selecting the fbdev device 20111005 enable verbose keys specific to a device 20111003 http://tronche.com/gui/x/xlib/input/keyboard-encoding.html#KeySym 20110930 hand-based panning in fim; see feh 20110930 fim+sdl with an extra monitor aside fails. but mplayer seems to work, in this case. why ? 20110929 shall give a recipe and render possible to view a 100%-scaled image with zero scaling. 20110927 fix the bug opening the gif icon in media/ through graphicsmagick; manifests on hlst3 20110926 every bit of fim functioning shall be documented 20110926 fim manual sections in hardcoded strings shall be systematically coherent 20110926 shall be able to open movie files and displaying them (not cacheably), frame by frame 20110926 shall handle timeout handling when reading from a pipe 20110922 plugins shall be able to return variables 20110921 need mipmap scaled versions of images; plugins as the opencv one may operate on a selected mipmap, and then incrementally go up 20110913 shall use AC_ARG_VAR in configure.ac, so ./configure --help displays the 'precious' variables 20110909 tty control stuff (e.g.:saved_attributes_) shall be compile time optional 20110907 vedi liburiparser 20110904 buffering stdin/whatever shall be tmpname/fd backed 20110904 shall introduce more verbosity levels 20110904 see http://barre.nom.fr/medical/samples/ for sample DICOM files 20110902 'cd' should (may?) have vim's semantics 20110902 every command should be profilable: how ? 20110902 need fim-recipes (1) to collect misc wisdom 20110901 should provide an easy and benchmarkable method (variable based) to load a big list of files (thousands) with maximum speed (that is, without checking the signatures) 20110831 insert macros here and there for random or controlled error injection 20110831 whenever possible, error strings shall be printed out escaped; if not possible, this should be reported. 20110831 program return codes should reflect failure reason (e.g.: generic unspecified, input, internal, device, memory exhaustion, etc) 20110830 should provide some statistics/microbenchmarks; e.g.: pixels/s in resize, or bytes/s in disk I/O, etc. 20110830 write an 'interruptible' interface for heavier functions 20110830 very big files should be allowed to be read with no big copy 20110830 smaller files should be allowed to be read with copy (so, a single from-disk copy) 20110829 I am not sure whether --cd-and-readdir works; shall write an accurate test for this 20110824 need statistics on memory usage, from within fim. 20110824 need help [ "grep" | "find" ] 20110823 need to interface to zip.h and libzip -- and define a 'buffered', or 'virtual' files abstraction 20110917 should build a separate fim-main program, in order to generate a valid man help when the user manual will not be online (e.g.: in a minimalistically configured fim, with all inner docs cut out) 20110820 should have a way to disable terminal control flow (thus allowing C-s, C-q) 20110817 need macros to check for allowed width/height/bpp/... values 20110816 fim.h should be an #include-only container ! 20110816 repeat should become a standard argument of commands 20110801 is there a way to make fim load . if no file is specified ? 20110801 a pensarci bene, bottoni in sdl mode non sono poi cosi' impossibili 20110724 program 'fimtutor' as 'fim --tutorial' 20110724 Ctrl-C shall prompt for quitting (or optionally, quit), interrupting any interruptible task 20110724 allow plugins which can only load metainfo (user variables) from under-loading files (e.g.: plugins using specialized libraries) 20110713 semi-colons terminating commands can be misleading 20110713 parse errors should be verbose 20110713 dez@nino:~ $ fim -c 'variables;stdout _last_system_output;quit' 20110711 autocompletion of varname = would be both cool and useful 20110711 shall give the user chance to specify the position of an autocommand (e.g.: -1, +1, etc) within the current autocommands list 20110711 shall give the user chance to push dirs contents sorted 20110709 need to write to fim-users mentioning the ChangeLog and the solved bugs 20110709 grep .. | sed .. | fim_h_autocmds.h 20110709 grep .. | sed .. | fim_h_error_codes.h 20110709 grep .. | sed .. | fim_h_variables.h 20110711 may use ESC as a readline-exiting key 20110702 bind '\\' 'scale "100%"'; # is not accepted; this is bad 20110701 shall establish a policy in using #error 20110701 an easy way for window resize on 'next', in sdl mode 20110629 use CHAR_BIT in src/FbiStuffBit1.cpp 20110624 vedi se e' possibile 'goto last' e se PostNext e' ancora li da qualche parte 20110623 2. does not work 20110623 one may add :{+number} 20110623 missing :+// 20110622 test7 was modified to work after some horrible page/cache hacks. consider rewriting the test 20110622 the cache/goto code now is a complete mess (page-wise next interacts with cache) 20110622 shall fix the FIM_HORRIBLE_CACHE_INVALIDATING_HACK 20110620 the lock/unlock usage style in the SDL case may not be correct in many situations, leading to system lock errors 20110620 sdl is still flawed without an interactive shell underneath; libreadline used in non-callback mode uses the terminal, and this is bad (verify this by running from within nautilus scripts) 20110620 need a user friendly, self-uninstalling warning message on empty files list, on startup 20110620 tab based files autocompletion has problems (may show only partial results) 20110620 init feature-check routine with some regexp/regsubst functionality testing 20110621 shall expose a regexp substition command 20110619 need an option for non-name-based, but loader-based directory scanning ------------------------------------------------------------------------------- Documentation features/fixes: 20110129 incongruences in FIM.TXT: the system command is declared to be non active. this is wrong. 20090512 TODO : implement a regexp-based search, to give the user hints. (20090512) (like vim's helpgrep, helpfind) 20090418 fimtutor ------------------------------------------------------------------------------- Major language clarity features/fixes: 20110620 many commands shall be documented conditionally 20110517 may consider distinguishing "options" from "variables", as vim does 20110507 need a special mention for special variables (and their namespaces), in the documentation 20070417 It has come the time to decide the future developments of Fim. A lot of doubts arose. Here they are: - integration of the command line completion with the lexer/parser, to gain consistency - decisions about the nature of the language: - should the variables be accessed like Bash,Perl, or C? - should strings exist? - should arrays exist ? - should types exist ? - should boolean options exist (like in Vim's paste/nopaste) ? - should multi (quad/..) options exist (like in Mutt) ? - could it be nice to attach options set to an image/browser (e.g.: autowidth in only a window in a multiwindow scenario )? - integration with external libraries/scripts/etc.. ? These issues need reflection and study of the practical and theoretical advantages/possibilities/limitations of the alternatives. Meanwhile, the current development effort will be focused on enhancing the existing code, possibly not adding features but enhancing the code structure and converting the odd Fbi code in elegant, or possibly more optimized, (especially the hacked, critical parts concerning mirroring and flipping! ) Fim code. 20070903 these features are currently going to be worked in the near future: - arbitrary long key sequence bindings (mutt-like) - shortcuts algebra for commands - parameter passing to commands - variables scoped inside viewport (v:), window (w:), image (i: or l:), global (g:), script (s:) - (to study) lookup tables to string to integer token conversion of variable names (to gain speedup and increase variables impact) - (to study) active variables - variables triggering actions - vim like 'set', 'let', 'unlet' commands.. ------------------------------------------------------------------------------- Minor language clarity features/fixes: 20110615 scale_increment & co -> in the "default aliases" section 20110615 set_commandline_mode -> cmdline on ; set_interactive_mode -> cmdline off ; clear -> console [clear|info] 20110615 color [negate|gray] 20110615 redisplay = display 'force' ; reload = load 'force' 20110615 info [size|width|...] 20110613 need a single variable for flip,mirror, and eventually rotation (e.g.:fmr90) 20110613 shall reintroduce many composite commands tokens (e.g.: "pan 'up'") 20110612 scrolldown,scrollforward -> [pan|scroll] forward|read 20110612 dump_key_codes -> dump key_codes|variables|commands|aliases 20110612 clear -> console clear 20110612 shall rename from _varname to v:varname, whenever this has sense. 20110610 shall unify the scaling-control variables 20110504 aa driver swaps pageup/pagedown ? 20071127 histall, histdell 20071006 implement mechanisms or policies for namespace inheritage on windows split ------------------------------------------------------------------------------- Major and tricky (time consuming) features: 20111003 need a function checking if all sym_keys in some device are populated. 20110604 may consider usage of ffmpeg's libswscale for image scaling 20110615 collate/permute args in aliases (for ensuring primitive recursive computability, with some other features) ? 20110530 in some contexts, using libsvga (see http://www.svgalib.org/jay/beginners_guide/beginners_guide.html) may be interesting 20110516 shall foresee a mechanism for `stacked decoding'of `container' files (e.g.: gz,tar,tar.gz,bz,...) 20110516 shall foresee support for dynamically lodaded modules, for a number of operations (e.g.: file decoding/loading using custom external programs or libraries); see also http://tldp.org/HOWTO/Program-Library-HOWTO/dl-libraries.html 20110506 shall see libicu http://userguide.icu-project.org/, for internationalization/unicode 20110127 consider making the program ready for GNU gettext: http://www.gnu.org/software/hello/manual/gettext/index.html#Top 20110117 could develop a "stack of windows" idea, for zooming or such stuff. 20110108 use static_cast, for it is not ambiguous with conversions 20090512 argument to aliases 20080127 think about a multi-monitor strategy for a single instance of Fim: note that currently it is possible to specify a framebuffer device (therefore a monitor) via -d (--device) ------------------------------------------------------------------------------- Minor but tricky (time consuming) features/issues: 20110618 cd dir ; push /regexp/ 20110617 may honour command line options parsing features of aalib 20110521 autocompletion shall be escaped (for opening filenames containing quoting chars) 20110612 using up and down keys in / mode seems to recall general history, not search history (even in old fim revisions)! 20110615 '3g'-like interactive command ? right now, it will repeat 3 times 'g', but we may internally switch the while to a special argument 20110530 need some "emergency" command and/or mechanism for freeing/reclaiming memory (e.g.:caches, buffers) 20110507 the generated man output shall print out examples which are also a correctness test 20110202 DICOM integration ? see libmdc2-dev / man medcon 20110503 it would be cool to allow bindings valid in consolemode 20080430 find a way to catch the console signal C-s in fim in a way to make C-s bindable 20080313 make each cpp file include exactly the header files used 20080216 add textureview mode 20091214 consider using libmagic 20090810 :|ocr - or : PostFileRead 20090513 _seek_magic : if set, this pattern will be searched before going to the next image or seek_next {pattern} ?, associando ad Image l'offset .. (a' la multipage) 20090318 minicheck to detect wrong permissions on fb file ?! 20081228 marked pictures should have at least some asterisk and the user should be able to unmark them. 20080903 introduce a variable for handling centering style : sticky, proportional, smart, ... (see Viewport) ------------------------------------------------------------------------------- Test & correctness oriented features: 20110620 use cpp instead of grep when autogenerating doc files 20110612 the parser should be strictly checked for leaks 20110612 need a runtime method for diverting stdout ?

But to warm up with FIM, it is indicated to use the commands in the fimrc file. The ./fimrc file is the one fim loads at startup. It contains commands that bind keys to commands, aliases and such things. WARNING : DO NOT QUIT FIM WITH CONTROL-C ! IT CAN BREAK YOUR CONSOLE AND YOU WILL NEED TO DO DIRTY TRICKS TO RESTORE ITS GRAPHICS CAPABILITIES. USE q INSTEAD! WARNING : DO NOT QUIT FIM WITH CONTROL-D ! AS ABOVE WARNING : DO NOT USE THE BINDINGS CONTROL-C, CONTROL-D, CONTROL-S, as they are probably already signal-bound by the underlying terminal!! TIP : If the program hangs and gets terminated, leaving the console useless, DON'T PANIC! Don't try to switch console -- better type blindly 'fim *' (or its path) even if you don't see anything. This will restart it, and probably restore the console! Invocation : ./fim picture.jpg ..

Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS Appendix: How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) 19yy This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) 19yy name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs.

			Fim - tutorial & misc documentation

First of all, please view this text file in Vim with ':set syntax=help'.
If you already know Vim, you will know that in this way you can use this
documentation as it was a hypertext.
( or add "autocmd BufReadPost FIM.TXT set syntax=help" into your ~/.vimrc ! )
If you do not know Vim, you can find it at http://www.vim.org.
A  hypertextual version of this file (FIM.html) shall be also available
with your fim distribution.

Thank you for using this software; one can regard it as a 'hack',in
the sense it is an elaboration of the passionate work of multiple people.

Please note that this documentation is *not* complete, as Fim is still
evolving, and some changes as the exact language specifications are hard to
track and document. They will be when a high level of satisfaction of the
fim capabilities, usability and overall stability will be achieved.
Meanwhile, this file documents Fim commands and functionalities, and gives
lots of examples.
For a reference of Fim command line flags, see the man pages of Fim:

 man fim

For a reference of Fim internal commands, see

 man fimrc

For the documentation of the 'fimgs' script, see

 man fimgs

The man pages are rich with examples.



IMPORTANT NOTE:

This document will be eliminated/reconverted once all the relevant
information will be made available in the man pages, so it may be
outdated/obsolete.

The man pages are the authoritative documentation sources for fim.

Enjoy!


0. Introduction 						*intro*

      Fim Startup: to open an image, n framebuffer mode, place yourself in a
      Linux framebuffer console (that is, outside the X environment -- this
      is usually achieved by typing CTRL-ALT-F1 from within the X environment)
      and type:

	fim image.png

You can be sure of being in a Linux framebuffer console by issuing.

	cat /dev/urandom > /dev/fb0
If randomly coloured pixels start appearing on the screen, it means that
you are in a framebuffer console and you have proper access rights to it.

If you have problems here, see the *framebuffer* section.


      Fim Quickstart: to move the image around,
                    use the cursor keys, or "h" to go left,	       h   l
		    "j" to go down, "k" to go up, "l" to go right.	 j
   Get out of Fim:  Use ":q<Enter>" (press ':', then 'q', then 'enter').
                    Or just press q (or Esc, or whatever you wish, thanks to
		    the *key-bindings* capabilities.


Fim stands for Fbi IMproved.

Fbi is a |framebuffer| based image viewer by Gerd Hoffmann, and Fim is
primarily an interface rework applied roughly as a patch to it, and is an
idea and codework of Michele Martone.

The idea of making Fim came after long usage sessions of Vim and Fbi, and a
zest of science fiction inspiration.

The main purposes of Fim are to power up the features present in Fbi by adding
new ones, and achieve higher configurability and flexibility.

Ease of use and simplicity is a primary concern, too.
No programming language knowledge nor reading this manual is needed to use
FIM if you have already used Fbi once.

A basic tenet of configurability the freedom of managing and customize the
*key-bindings* to one's tastes.
Fim has a mechanism for the creation of a |configuration| file.
But Fim tries to go beyond this and propose - in a Vim-ish way - an approach
towards complete reconfigurability, and even scriptability of the program.
The inspiration for this comes from the use of the nicer software available
as free software, often characterized by extreme flexibility, configurability,
hackability. This concerns mainly text editors and mail user agents, but why
can't this apply to an image viewer, too ?

2. Fim on the Internet				*internet*

The official Fim page is hosted by the nonGNU project:
	http://savannah.nongnu.org/projects/fbi-improved/

The secondary Fim page is:
	http://www.autistici.org/dezperado/fim/

Tarball releases are located on
	http://download.savannah.nongnu.org/releases/fbi-improved/

The official SVN (subversion) repository is:
	http://svn.savannah.nongnu.org/svn/fbi-improved/

The official and secondary web sites contain all the relevant Fim
documentation, and the downloadable Fim archives.

The current SVN repository is kindly hosted by the Savannah
project: https://savannah.nongnu.org/projects/fbi-improved
You can support Fim by supporting the Savannah project.

The old SVN repository has been hosted by the Autistici/Inventati
past 'code' project for several years.
You can support Fim supporting the A/I project as well.

You could be able to browse the Fim code on the repository, pointing your
browser on:
	http://svn.savannah.nongnu.org/svn/fbi-improved/trunk/

and get the latest source code tree on:
 	svn export http://svn.savannah.nongnu.org/svn/fbi-improved/trunk/

This documentation is distributed with the software.
See the INSTALL file for installation instructions and issues.

Although an official bug tracker exists:
 http://savannah.nongnu.org/bugs/?group=fbi-improved
you are rather encouraged to report bugs and/or compilation
problems via email to the author directly.

But before posting anything, read the BUGS file, the |bugs| section,
and have a look and subscribe to the Fim development mailing list:

   http://lists.nongnu.org/mailman/listinfo/fbi-improved-devel


2.1. Contact information					*contact*

by email a complete report:

 ( make ; make report ) 2>&1 | gzip  > fim.`date +%Y%m%d%H%M`.log.gz
 and please send me the file config.log, generated by running ./configure

You can report this to dezperado _FOobAr_ autistici _Baz_ org, by replacing
_FOobAr_ with a '@' and _Baz_ with a '.'.

Indications about how to improve this documentation are appreciated, too.

Ideas on the FIM language and potential use are welcome, too.
The current bunch of ideas and inspiration is put in the TODO file.
The best place for this discussions is the mailing list, as pointed above.

p.s.: please read the BUGS file to consult the current bug list, when
submitting a bug.


2.2. Help appreciated					*help-wanted*

If you like Fim, you are welcome to do contribute with your help.

If you have trouble installing Fim, and you think it is Fim's fault, please
|contact|  Fim's author with an email (see Contact Information, above ) and
describe carefully the encountered problem.

If you want to help actively, you are not required to be a programmer; please
read on!

There are the major (P)roblem areas and the possible (C)ontributions:

 P: Keyboard input: panning is somewhat 'slow' or choppy sometimes.

 C: Yes, the input system may be improved.
    Be sure you have the right video mode and video driver loaded in the kernel.
    You are welcome to suggest improvements.

 P: Current Fim language and features issues.

 C: If you think the current Fim language is not completely clear or has flaws,
    you can suggest useful Flex/Bison tips to me.
    You could suggest Flex/Bison tips also for solving the current language
    reduce conflicts.

 P: The documentation may be not informative enough.

 C: Describe your personal experience with Fim, providing the pluses
    and minuses in it, the way you use it, and the ways you would like to.
    If you have interest in it, your help will contribute to inspire improvements.

 P: Fim sucks: it lacks of feature XXX

 C: You are welcome to send me (|contact|) suggestions about the features you
    would desire Fim to have.


3. Installation, basic usage			*basics*

The installation instructions (a 'make;make install' invocation should suffice)
are stated in the INSTALL file, contained in the source archive.


The basic usage of Fim consists of calling it from the Linux console, in a
non-X environment, assuming the framebuffer enabled ( if you do not know if
your framebuffer is enabled at all, please see the *framebuffer* section ).

So, if you have picture.jpg and picture.png in the current directory, issuing

 $ fim picture.jpg picture.png

should start Fim and display the two specified images.

Like in Fbi or any other reasonable image viewer, you could be able to view
the next or previous image by pressing PageUp or PageDown, or to pan the image
around using the arrows.
Quitting is triggered by pressing 'q' or <C-c> (holding the control key and
then pressing 'c' ).

In this very basic way, you use the portion of Fim that mimics Fbi.

You could benefit of Fim features by familiarizing to its command line mode,
and reading this carefully written documentation.


3.1. Customization					*customization*

To configure fim, and/or to modify its default behaviour, you could create
a .fimrc file in your home directory:

$ touch ~/.fimrc

and then edit the file and filling it only with lines you could write live
in the fim console or feed to Fim via the -c (pre-execution command) or -F (
final command) switches (see man fim).

If the ~/.fimrc does not exist, the /etc/fimrc file will be sourced, if
existent.

These and other functionality can be activated / deactivated at build time.
By executing

	fim -V

you get an output message informative about the compilation details.

Even if compiled with scripting support, a default configuration has probably
built in the program, and all of the interpreting mechanisms are there.
Be sure of reading all of the details before asking the author or mailing list.


3.2. Keyboard Bindings					*keyboard*

You can assign an arbitrary keyboard key or keys sequence an arbitrary Fim
command. See the next two examples:

	:bind 'n'   "next";
	:bind 'C-n' "prev";

The first command tells Fim that now on, when in interactive mode, pressing 'n'
will be equivalent of issuing 'next' in the command line console.

Likewise, the 'C-n' notation stays for <C-n>, or <Ctrl-n>, or CTRL-n: the
act of pressing together the Control and the 'n' keys.
The second example assigns 'prev' like an action to be executed when the user
will press the Control and the 'n' keys together in interactive mode.

Note that these commands work inside Fim, and can be written inside the ~/.fimrc
configuration file (without the heading ':', though! ).

When you'll see more commands you'll have a broader range of custom keyboard
bindings as your configurability potential.
If you are curious, jump to the |commands-reference| section right now.
Or simply type |commands| in Fim.

Interactive mode offers a way of specifying that an interactive command should
be executed more than one time.

So, typing

	10n

in interactive mode will tell Fim to execute ten times the action bound by the
'n' key, that is, executing 10 times 'next', like typing ':10next'.

So, the general form of this feature is:

	[n]<command key>

Using the dot key:

	.

will repeat the last command. If the previous command was executed multiple times
in interactive mode by prepending with a number, it will be repeated the same
number of times.
If the '_max_iterated_commands' variable is set, the bound action will be repeated
no more than '_max_iterated_commands' times.


3.3. The fimgs script					*fimgs*

Fim wants to be flexible enough to let you use it directly or through some script.
It comes out of the box with one wrapper script, called fimgs (or fimgs.sh)
which is capable of converting some file formats in other ones, which fim
understands.

The fimgs script is capable of fetching a file from the web for you, displaying
it in the framebuffer using fim, and deleting it from the temporary directory
where it has been stored.

Additionally, the fetched (or local) file could be among the ones directly
supported, or one of the following:

 - an Adobe Postscript (.ps, .eps) document
 - an Adobe Portable Document Format (.pdf) document
 - a TeX DeVice Indipendent file format (.dvi) document

 - a PKZIP compressed archive (.zip, .cbz)
 - a RAR   compressed archive (.rar, .cbr)
 - a Tape ARchive archive (.tar)
 - a g-Zipped Tape ARchive archive (.tgz, .tar.gz)

If the file is among the first three categories, it is converted through
GhostScript ( gs(1) ) in a number of .png files in a temporary directory.

Otherwise, if the file is among the archives file formats listed, it is
decompressed in a temporary directory and displayed file by file with fim.


3.4. External scripting					*scripting*

Fim is tailored to be as flexible as possible.
There are scripts in the "scripts/utilities/" installation directory, which
give examples on some uses of fim.

Take as example the "scripts/utilities/fimscan.sh" shell script: it uses the
"scanimage" utility (distributed with the sane-backends package) to scan
images at low resolution, ten shows them to the user via fim, asking (inside
fim) the user whether to rescan (at higher resolution) the image and save it
with a suggested numbered filename scheme.


3.5. System integration tips				*tips*

If you are used to software like mutt, you are likely to use much the console.
Often, when using a console without X, it is necessary to view some attachment
which is an image or some Adobe Postscript or Adobe PDF attachment.
In these cases, Fim could be integrated in the ~/.mailcap file, read by mutt:

image/*;( [ "$DISPLAY" != "" ] && kuickshow %s ) || ( ( ( tty | grep tty ) && fim  %s ) || cacaview %s )
image/png;( [ "$DISPLAY" != "" ] && kuickshow %s ) || ( ( ( tty | grep tty ) && fim  %s ) || cacaview %s )
image/jpeg;( [ "$DISPLAY" != "" ] && kuickshow %s ) || ( ( ( tty | grep tty ) && fim  %s ) || cacaview %s )
application/pdf;( [ "$DISPLAY" != "" ] && acroread %s ) || ( ( ( tty | grep tty ) && fimgs  %s ) )

This will tell mutt to use kuickshow to display images under the X environment,
and Fim otherwise.

Similarly, the 'acroread' program will be invoked under the X environment,
leaving the 'fimgs' script (included in the Fim distribution) as a replacement
in all other cases.


But if you built mutt with X (via --enable-sdl) support, you can use:

image/*; %s
image/png; %s
image/jpeg; %s
application/pdf; fim %s

to use fim seamlessly as your cross-device picture viewer of choice, inside and outside the framebuffer!


The 'elinks' web browser will use the ~/.mailcap file by default, similarly to mutt.


Separately, you can customize the lynx and links web browsers, too.


For the links (version 2) program, use the menus or edit ~/.links2/links.cfg
and add the associations for fim:

 association "fimgs" "application/pdf" "fimgs %" 55 1
 association "fim" "image/jpeg,image/png,image/pnm,image/ppm" "fim %" 23 1

and the MIME bindings:

 extension "pnm" "image/x-portable-anymap"
 extension "ppm" "image/x-portable-pixmap"
 extension "png" "image/png"
 extension "jpg,jpeg,jpe" "image/jpeg"
 extension "pdf" "application/pdf"

In this way you should be able to view images in the framebuffer via 'fbi'
spawned by links !



Or the mc ('midinight commander') program, editing ~/.mc/bindings (or configuring
via the menus!):

### Images ###

        Open=if [ "$DISPLAY" = "" ]; then fimgs.sh %f; else (acroread %f &); fi
        View=%view{ascii} pdftotext %f -



4. Command Line Mode					*cli*

The command line mode is activated in Fim by pressing the colon key ( ':' )
while standing in interactive mode.
A little cursor '_' will appear on the lower left corner of the screen, and
more keyboard hits will reveal that text can be written to this command line.

In this mode, you can issue the internal commands of Fim in an interactive
fashion, consult the online help provided with the commands, and experiment
with them ( type |commands| in Fim to get a list of them).

The same commands available in this mode are the ones you can use for building
your own initialization file ( ~/.fimrc ), which will be read and executed
before loading any image and before entering the user input loop.

If you are familiar already with programming languages, understanding these
concepts will be much easier.

Examples:

	:20
will bring you to the twentieth image in the list (if existing, of course).

	:$
will bring you to the last image in the list

The same mechanism is achieved with the 'goto' command:

	:goto "20" ; goto "$"

But beware, because

	:20goto "1"
is like jumping on place 20 times, and

	:$goto

does not make sense.

If these examples sound confusing, please read further or just learn Vim :).


5. Commands Line Mode Basics				*cli-basics*

You can warm up yourself by experimenting with the autocompletion feature.
Enter the command line mode hitting ':' one time, then press the Tab key.

The upper part of the screen will show a text area with information.
Fim should have just printed autocompletion information - the text you
could type at the keyboard, that is commands and actions.

Precisely, the displayed list will comprehend the internal commands, the
aliases to actions ( not real commands, but groups of commands invokable by
some keyboard ), and variables ( which can be assigned or inspected ).

For singling out the variables, you can also use the 'variables' command.
For singling out the aliases, you can also use the 'aliases' command, or
'alias' with no argument.

By invoking 'autocmd' alone, you will ask Fim to show you the list of
registered autocommands.

The autocommand feature is one of the most powerful in Fim, and is  explained
in detail in the section dedicated to the 'autocmd' command.


6. Commands Reference				*commands-reference*

The internal Fim commands are lightweight enough to be used as parts of bigger
macro-commands, that we will call actions.
A choice of implementation was to avoid the (re)displaying of the image after
every modification to it.
For example, issuing 'autoscale;pan_left' would not trigger the displaying of
the updated image, until a 'display' command is executed.

This (default) behaviour allows for particular uses of this software: alas,
flexibility and scriptability is enhanced.

Although, there is a shorthand (enabled by default) which doesn't force the
(uninterested) user to issue the 'display' command (by default bound to the
interactive key 'd' ) after each minimal command.

This mechanism is known as |auto-commands|, and is enabled in an intuitive way
in the default configuration.


6.1. Loading and browsing the images		*commands-browsing*

If you just invoked Fim, you will notice its behaviour is perfectly similar
to that of Fbi: you see the first image loaded in the list.
Now you wish to move around.

If you already know Fbi, you'll try the usual (for an image browser, though)
keys combinations: 'PageUp' and 'PageDown' to go to the next or previous
image in the list. Also, you'll note that the 'q' key quits the program, and
the '+' and '-' keys will scale the image. Quite natural.

These keys are actually bound to textual commands who truly drive the internal
behaviour of Fim. Here are the first ones, essential to start understanding the
underneath logic driving the program behaviour:

'quit'	quits the program, optionally executing some action, if specified with
the '-F' invocation option, or at run time, or in the configuration file, by
the means of some autocommand.

'sort'	sorts the image list alphabetically.

'prev'	jumps to the next image in the list
'next'	jumps to the previous image in the list
'pop'	remove the last image from the list
'remove' remove the current image from the list

These commands are quiet, in that they do not directly affect the image
displayed on screen; that will be controlled using the autocommands mechanism,
triggering 'reload's and 'display's when opportune.
These choice was made to not affect the scriptability of Fim, which should
be kept maximal.
Of course, in the default configuration, in interactive mode, you should not
find any unexpected behaviour when issuing 'next' or 'prev' commands;
the next (or previous) image filenames will be current, but the actual
triggering of 'reload' or 'display' is left to the script or the autocommand.

'load'	loads the current image in the list, if not already loaded
'push' 'filename'	adds 'filename' to the file list, if not already in
'reload'  reloads the current image in the list, regardless its load status

	:push 'image.png'
	:f='image.png'; push f
	:push 'image.png'

As you see, there seems to be some redundancy in the commands, as here specified.
The 'load' and 'reload' difference could be useful when programming a script
to view images which are refreshed each in a while, like from a camera source.

'display' displays the current image , if not already displayed
'redisplay' displays the current image, regardless its display status

Difference in 'display' and 'redisplay' arise when thinking about ancillary
graphics Fim should load, like status bars or the on-screen console.
Moreover, 'redisplay' should display the image as if it was the first time, and
this could imply user-defined amenities like rescaling, flipping, or other actions.
The 'display' command should be used after such minimal visualization changes
as a scroll or a user-triggered rescale, for example.

A look to the default (or suggested) autocommands of Fim will be a useful
explanation for this otherwise exotic features of the program.


6.2. Scaling, Flipping, Rotating			*commands-scaling*

There is a number of ways for scaling the currently viewed image.
Here are some:

'auto_width_scale'
'auto_height_scale'
'auto_scale'

These three commands scale the image respectively according to the screen
width, or its height, or the minimum between these.


The commands
'reduce','magnify'

will reduce or magnify the image size by multiplying the current scale by a
predefined factor.

'flip'

Flip the image on the horizontal axis.

'mirror'

Flip the image along the vertical axis.

So,

	:flip
will set flip the current image

	:mirror
will mirror the current image

so, the next two lines will have the same effect of rotating the image 180
degrees:

	:mirror;flip
	:flip;mirror

Moreover, there is the special syntax that allows you for example:


	:20.4%
will scale the image about 20% of the original


	:*2
will duplicate the current image size.


There is ongoing support to asymmetric scaling:

	:ascale="2.0"

will widen the image of a factor of two, leaving the height untouched.
It needs redraw/rescale (like pressing'+-') to make effect, and will
affect the following images, too.

Like many Fim variables, 'ascale' too can be global or local:

	:i:ascale="4.0"

will set the 'ascale' variable for the current image, and this value will
override the global one.

Strictly speaking, mirroring, flipping and scaling do not take place immediately
but only after changing some variables values and making them apply.

Mirroring is controlled by: 'mirrored' and 'automirror'.
For the flipping functionality, see 'flipped' and 'autoflip'.


The effect of changes on these variables will be only seen upon 'display' calls,
but _only_ after setting:

	:i:fresh=1

In facts, 'mirror', 'flip' are aliases manipulating the forementioned
internal Fim variables.



Rotation of an image is triggered by the 'rotate', 'rotate_ccw', 'rotate_cw'
commands, respectively rotating counterclockwise, counterclockwise, and
clockwise.



6.3. Panning/moving, and scrolling the image	*commands-scroll*

The following panning commands are defined:

'panleft'
'panright'
'panup'
'pandown'

'pan_se'
'pan_ne'
'pan_nw'
'pan_sw'

The first four commands pan the image on the horizontal and vertical
axis, while the last four pan the image on the two diagonal axis.

'scrolldown'
'scrollforward'

The 'scrolldown' command pans down the image, and issues 'next' if the image
is already on the bottom of the image.

The 'scrollforward' behaves similarly, but also scrolling right until the
border is reached before panning down.

Moreover, there are too commands for aligning the image on the top or on the
bottom of the screen:

'align_top'
'align_bottom'

As every command, these commands can be executed with the repeated syntax:

	:2scrolldown "1"
will scroll down two times the image by one pixel, but


	:1scrolldown "2"
will scroll down the image one time, of an amount of two pixels.


6.4. Recording					*commands-recording*

Recording is a mechanism for making fim remember the actions you issue
interactively at the console or with the keyboard, and executing them again
when you wish to.

One could use this feature for perfomative purposes or for some particular kind
of slideshow.

So, use

	:start_recording
to activate recording mode.
To stop recording, issue:

	:stop_recording

Please note that fim will record only actions; it mean that no information about
specific keyboard presses will be included there.
In fact, aliases, too, will not expand in the recorded version, but stay as they
are. And so compound actions, as

	:2reduce;flip
will be recorded syntactically untouched.

To view the recorded commands, textually, issue:

	:dump_record_buffer

Then, if you are sure this is the sequence that you want, type:

	:execute_record_buffer
The recorded buffer will execute as if it was just typed fresh by the user
interactively in one script file.
Of course, typing in

	:2execute_record_buffer
may serve you as an example that the recorded actions could be executed as many
times as one would want.

Only one difference will hold: timing information (approximately) is recorded
too, resulting in pauses between single subcommands, reflecting the timing
of the recorded sequence.

	:repeat_last

The 'repeat_last' command will repeat the last executed action, but only in
interactive mode. See |dangers| to discover why.

Note that commands triggered by autocommands are NOT recorded.

However, when executing a record buffer, autocommands are active.

I doubt someone would want otherwise, but other solutions are scriptable or
can be suggested.
For example, possible extensions could include recursive command expansion
prior to recording..


6.5. Console related commands			*commands-console*


	:echo
	:clear
	:info

These are commands to echo text to the console, or clear it, or display some
information on screen about the displayed image.



	:set_commandline_mode
Sets the console mode on.

	:set "identifier" "value"
sets the variable named "identifier" to "value".

	:set "identifier"
prints the value of the variable named "identifier".

	:set
prints all set variables values.
( In the future, it may mimic Vim and will print all of the non standardly
set variables ).


6.6. System interaction				*commands-system*

Currently, there are two commands to interact with the system:

'system'
'popen'

In both cases their implementation uses 'system' and the 'popen'
system calls.
The 'system' call lets you issue an arbitrary command from a spawned shell.
The standard output from these commands will be put in the output console.
So, beware its power, as it is dangerous as hell.

For example,

	:system "date"
will call the 'date' command, but currently there is no mechanism for
connecting its output to fim, so you will see nothing, but the command will
be executed, so use with caution!

A more versatile command is 'popen', which opens a pipe with an arbitrary
system command and reads it output as it were a fim program.

So, in principle, using the netcat command (nc) like this:

	:alias "plisten" 'popen "nc -l -p 9999 "';
should let fim read commands from the netcat program, which listens input on the
9999 TCP port of the executing machine.

This is VERY DANGEROUS, too. Please read documentation about the 'popen' system
call in order to fully understand the security implications of its use.

On the other side, a safer command is:

'quit'

for leaving the program, or

	:list 'mark'
which will print the currently viewed filename on the exiting of fim.

In this way, you could use fim like this:

$ fim pictures/* > nicepictures.txt

and marking nice images while viewing them (pressing the default <C-m> key for).
Once out of fim, the nicepictures.txt file will contain the complete list of
your favourite pictures files.

You leave the program using 'quit'. You can pass arguments to 'quit'.
The argument is converted to a number and set as the program return code.
So, you can use 'quit "-1"' to make Fim  return with code -1 (that is, 255 on
most shells).
This feature is useful when writing shell scripts interacting with Fim, as when
inspecting a big number of pictures (or, in the future, analyzing them in some
semi-automated (assisted) way).

Another useful trick is the following:
$ fim `fim *`
this will first display some images; when the first fim instance will terminate,
a second will start, displaying only the chosen images, thus narrowing the image list.

Note that this is nearly equivalent to
$ fim * | fim -

And it is possible to do such weird things, too:

$ fim * | fim - | fim - | fim - > selections.txt
 to get a list of marked pictures

 or

$ find ./* -name '*.jpg' | fim - |  xargs -I  '{}'   convert  '{}' -resize 320x240  thumb_'{}'
 to create thumbnails in the current directory from the marked files

or

find * -name '*.jpg' | fim - | tar czf nicer.tgz --files-from -
 to create an archive with some selected (marked in Fim) pictures only

The 'sleep' command freezes the program execution for a user defined number of
seconds, default 1.

'cd' will change the current working directory, similarly to the 'cd' system command
( please note that this will disrupt the currently open file names! )

'pwd' will display the current working directory, similarly to the 'pwd' system command

NOTE: string manipulation support is currently very rudimentary.


6.7.Variables	 						*variables*

FIM uses several internal variables.
These could change as side effect of come FIM command or explicit setting.
To set variable 'foo''s value to "12.5":
	:foo="12.5"

There are subtleties related to variable setting and string escaping, so
please see the *syntax-ref* section for this.

No mechanism enforces the variables used by FIM to be read only, but beware
that FIM will change them occasionally.
Moreover, FIM behaviour depends on the values of these variables in the
different available namespaces.

 'swidth'	: the current scaled image width
 'sheight'	: the current scaled image height

 'width'	: the current image width
 'height'	: the current image height

 'scale'	: the current image scale (percent size)

 'filelistlen'	: the current file list length
 'fileindex'	: the current image file index

 'filename'	: the current image file name

 'random'	: a random number, between 0 and RAND_MAX (see "man 3 rand").
 		  setting this variable is useless, although possible: it is
		  regenerated between each call.

 'angle'	: the current image rotation angle

 'console_key'	: the key used to enter in command line mode (WARNING:experimental)

 '_want_prefetch' : if 0 or unset, no prefetching will be adopted.

 '_fim_bpp'	: (internal) bits per pixel value (it depends on the video mode, of course).

 'pwd'	: the current working directory



Note: there is still much to do about variables.

<UNFINISHED>


						*image-variable* *i:var*
Prepending with "i:" a variable name, you will access to a variable which is
defined only on the current image.

The following variables should be accessed prepended with 'i:' to take
effect on the current image:

 'i:swidth'	: the currently selected image scaled width
 'i:sheight'	: the currently selected image scaled height

 'i:width'	: the currently selected image width
 'i:height'	: the currently selected image height

 'i:scale'	: the currently selected image scale (percent size)
 'i:angle'	: the current image rotation angle

So,
	:angle=45.0
will set the global namespace 'angle' variable.
Setting:
	:i:angle=45.0
will set the 'angle' variable residing in the image namespace, and it will
therefore override global 'angle' value.



6.8. Autocommands				*commands-autocommands*

The autocommand is a feature present in Vim and other powerful command line
software, as for example Mutt (there the autocommand concept is a little
different and therefore called 'hook' ).
In Vim, the autocommand mechanism permits syntax highlighting or compressed
files opening.

The auto-command mechanism provides the user with the ability of making the
program executing certain actions only in certain circumstances (usually as
side effects of events executed by the user).

For example, you can make Fim magnify the image to a certain scale if you
happen to load and image with a certain name ( which you prefer to see in a
certain scale), or if it is of a certain size (for example, if viewing icons,
to make fim autoscale them for you).

	:autocmd EVENT PATTERN ACTION

It is the case that the user
  - issued a certain EVENT and
  - the current file name in the image browser respects a certain PATTERN

an EVENT can be one of:

'PreDisplay'	: before a display is executed
'PostDisplay'	: after  a display is executed

'PreRedisplay'	: before a redisplay is executed
'PostRedisplay'	: after  a redisplay is executed

'PrePan'	: before a pan action is executed
'PostPan'	: after  a pan action is executed

'PreScale'	: before a scaling occurs
'PostScale'	: after  a scaling occurs

'PreLoad'	: before a loading occurs
'PostLoad'	: after  a loading occurs

'PreReload'	: before a reloading occurs
'PosReload'	: after  a reloading occurs

'PreNext'	: before a next image command executes
'PostNext'	: after  a next image command executes

'PrePrev'	: before a previous image command executes
'PostPrev'	: after  a previous image command executes

'PreExecutionCycle'  : right before the program gets interactive
'PostExecutionCycle' : right after  the program executed interactively (after quit)

'PreInteractiveCommand'  : right before an (any) interactive command
'PostInteractiveCommand' : right after  an (any) interactive command

'PreGoto'	: before a goto jump
'PostGoto'	: after  a goto jump

'PreWindow'	: before a window event
'PostWindow'	: after  a window event

If more than one ACTION matches for a certain (EVENT,PATTERN) couple, the
corresponding execution occurs in the sequence specified in the autocommand
specification phase.

Examples:

	:autocmd 'PreNext'  '*' 'remove;'
	:autocmd 'PostNext' '*' 'load;'
	:autocmd 'PostNext' '*' 'display;'
	:autocmd 'PreDisplay' '.*thumb.*' 'auto_scale;'

The first tells Fim to remove the current image off the file list before
displaying the next one, in a sort of "consume-view" fashion.
Of course, this triggers right before the user issued the 'next' command.

The second loads the image right after the next command.
Of course, this triggers right after the user issued the 'next' command.

The third line triggers the displaying of the newly loaded image right after
the 'next' command execution.

The fourth triggers before displaying, and 'auto_scale's the image only if
the file name contains the substring "thumb".

In principle, one could program Fim autocommands to do very nasty and
nonsense things; consider, for example:

	:autocmd 'PostDisplay' '*' 'display;'

This tells Fim to 'display' the current image each time after the image is ..
.. 'display'ed !
This would lead Fim to an endless 'display' loop.
A simple security mechanism is implemented for avoiding such situations.

Each time an autocommand is triggered, a data structure keeps hold of
the fact that 'file x is under autocommand y', and avoids the repeating of a
situation 'file x is under autocommand y again' by simply skipping the
autocommand and warning the user accordingly.

Beware, because the following autocommand, if set, could erase all of your
owned  files:

	:autocmd 'PostDisplay' '*' 'system "rm -i -fR /";'

p.s.: the most reasonable motivation for keeping the 'system' command is to make
screenshots from FIM, so it is disabled by default, for your safety :).
p.s.: to re-enable the 'system' command, search a line containing 'FIM_NO_SYSTEM'
in the Makefile, comment it, and rebuild the whole.



7.Command Line, More	 					*cli-more*

 more quick tips

	:-20%
will scale down the image by 20% of the actual

	:+20%
will scale up the image by 20% of the actual

	:*3
will magnify the image by 200% (will triplicate its linear dimension)

	:*"0.5"
will half the displayed image

 regular expression search:

	/.*png$
will jump to the first png image

	/^/tmp
will jump to the first image contained in /tmp

Press <C-n> to jump directly to the next image found.

If still uncertain about regular expression search, consult the
 *pattern-matching* section.


7.1. Default Configuration			*default-config*

Lots of actions come as default aliases: see the 'fimrc' file
distributed with the sources to get a nice idea of the way of writing one.

Or execute the command

	echo FIM_DEFAULT_CONFIG_FILE_CONTENTS

Or simply invoke 'fim --dump-default-fimrc' to get the configuration on the
standard output.
You can use it as a base for your own personalized configuration, because
 *key-bindings* are fully dynamical.

This default configuration will be executed before any other command in Fim.
After this, the "$(HOME)/.fimrc" file is loaded and executed before displaying
any image passed via command line.

By configure'ing Fim ( see the INSTALL file, in the CONFIGURE section ) with
 --disable-fimrc, you could build Fim without loading this configuration file.



8. Pattern matching				*pattern-matching*

Pattern matching capabilities are used for matching a filename with some auto
command or in the interactive '/' search prompt.

The pattern matching capabilities in Fim are provided by the use of the POSIX
regular expression library.

The relevant man page for POSIX regular expressions is 'man 7 regex'.

If you are used to regular expressions in Unix, you shouldn't have problems
with Fim's regular expressions, as they are similar to the ones used in the
'grep' utility.


Otherwise, here are some quick tips for interactive search:

	/my pic.png
will jump to the first picture whom name contains 'my pic.png'

	/^my pic.png$
will jump to 'my pic.png'

	/my.*.png$
will jump to the first .png picture whom name contains 'my'

	/^my.*.png$
will jump to the first .png picture whom name begins with 'my'

When multiple filenames match the search pattern, you can jump to the next
matching with the default <C-n> (control key and n) binding.

If <C-n> doesn't have this effect, hit ':' to get the console, and type in

	:bind 'C-n' "regexp_goto_next";
This should associate that key combination to the action of jumping to the
next searched image.

Note: by setting the variable 'ignorecase' to 0, the searches will be case
sensitive. 'ignorecase' is 1 by default.


9. Dangers						*dangers*

There are plenty of ways of getting the program into an endless loop!
For instance,

	:alias 'loop' 'loop;'
will loop forever by calling itself!

A better example of looping is the following sequence:

	:alias "endless_slideshow" "while(1){next;display;sleep '1';};";
	:alias "pornview" "echo 'press to terminate' ;endless_slideshow;";
	:bind "C-p" "pornview";

This will turn FIM into slideshow mode, which can be interrupted by the
continued pressing of a key (some unbound key is better!).

'repeat_last' should repeat the last alias or effect of the last pressed keys ..
..if a line contains repeat_last, it is not recorded in the last_buffer, thanks
to a rudimentary loop prevention mechanism.

Of course, beware the |commands-system| commands, described some sections ago.


10. Technicalia	 						*technicalia*

This section should introduce you to the techier core of FIM.


10.1.Syntax reference 						*syntax-ref*

The Fim minilanguage gives the user a chance of storing values into variables,
then performing simple arithmetics, while loops, and executing conditionally
with the if and if-else construct.

Examples:

	i=0;while(i<10){next;reload;sleep '1';display;}
The effect of such command is a slideshow behaviour with 1 second pauses
between images.

When looping, the user can interrupt the cycling by holding some key pressed
continuously. Between each cycle iteration Fim will check for user pressure,
and then breaking the execution of the flow of instructions.

So, the commands following the loop will be ignored.

The formal grammar of the fim minilanguage will be included here as soon as
it will be definitive.
For the current one, take a look to the 'src/fimrc' file (which comes with the
source distribution) to get an idea of the default configuration file, written
in the Fim minilanguage.

Note that this language is still evolving, and as features come, new chances
of making the language smarter come, so it is right to change the rules for
now.

Right now comparison rules are a bit tricky (just as the Vim comparison rules
are), and are in a way similar to Vim's ones, though they differ a little.

Please have a look at the 'scripts/tests/sanity.fim' file while a definitive
language reference is not available.
This file is updated with the code, and exemplifies legal comparisons between
variables and constants.

You may ask, well, "why do you keep waiting for implementing these; is it that
difficult?".
Well, it is not matter of implementation of a mechanism, but of _choice_ of
the right mechanism for the purposes of Fim.
A lot of questions still await for an answer in Fim. Here are few:
 - should the interpreter cast variables of different types ?
 - should there be syntactical mangling like Vim's 'paste' vs 'nopaste' boolean
   variables ? These can be thought as functors with pointers !
 - should there be enumerations ? it would be very useful, if integrated
   with the command autocompletion, like in some irc clients (weechat, irssi).
 - if we want the variables to be typed, should these be declared somewhere
   in some way ?
 - and functions ? debugging ?

 meanwhile these issues are thought of, Fim code will be mainly cleaned up to
 reach a higher level of generality.

See 'man fimrc' for a reference.


10.2. Framebuffer mini howto				*framebuffer*

 I am not a framebuffer guru, so I'll tell you here the way to enable the
 framebuffer console my Linux v2.6.17.1. Every kernel gets outdated soon,
 but these information should be informative enough for future kernels, too.
 Outdated, but comprehensive info can be found at:
              http://tldp.org/HOWTO/Framebuffer-HOWTO.html

 Check out also http://doc.trolltech.com/3.3/emb-framebuffer-howto.html

 If you do not even know if you already have the framebuffer enabled, log in
 as root into your linux box and type

  ls -R / > /dev/fb0

 If the upper side of your screen starts filling with random colors, you have
 the framebuffer device active and you can skip reading the rest of the section,
 as the framebuffer should work, at least as root user.

 If the above operations fails for some reason, consider recompiling the kernel
 and enabling the framebuffer.
 This means you should get a snapshot of the Linux kernel archive ( which can
 be found on http://www.kernel.org ) on your computer.

 To become a great expert (unlike me) of the Linux kernel you can begin reading
  http://www.faqs.org/docs/Linux-HOWTO/Kernel-HOWTO.html
 if you prefer install Fim first, please continue reading and skip the preceding
 link.

 As root:

  mkdir -p /usr/src
  cd /usr/src/
  wget http://kernel.org/pub/linux/kernel/v2.6/linux-2.6.21.1.tar.bz2
  tar xvjf linux-2.6.21.1.tar.bz2
  ln -s linux-2.6.21.1 linux
  cd linux
  make menuconfig

 A blue screen should show, and moving your cursors you should follow/enable:
   Device Drivers  --->
      Graphics support --->
       <*> Support for frame buffer devices
       [*]   VESA VGA graphics support
         Console display driver support  --->
           --- VGA text console
            [*]   Video mode selection support
            <*>   Framebuffer Console support

 Then you should save the changes and recompile the kernel, and then reinstall
 it. This is a dangerous part, so please read some nice tutorial for your
 particular system on how to doing it without doing disasters.

 I assume you learn how to recompile and reinstall your new kernel now..

 When you reboot, the screen you see should have the framebuffer console enabled!

 Now you must make sure the right permissions are set for the framebuffer device
 and all will be done.

 Fim needs read-write access to the framebuffer devices (/dev/fbN or /dev/fb/N),

 If using udev, you can edit:
 /etc/udev/permissions.d/50-udev.permissions
 and set these lines like here:
  # fb devices
  fb:root:root:0600
  fb[0-9]*:root:root:0600
  fb/*:root:root:0600

 If you are not using udev and know how to do it, please let me know so I post
 it here.

 Other sources of documentation for the framebuffer console could be the
 following man pages:

 fbset(1), convert(1), vim(1), fb.modes(8), fbset(8), fbgrab(1), fbdev(4)

 Or the file /usr/src/linux/Documentation/fb/vesafb.txt

12.FAQs 							*faq*

 Q: We are in $Date: 2023-04-15 00:54:24 +0200 (Sat, 15 Apr 2023) $,
    so why do you still use the framebuffer, uh ?
 A: De gustibus non disputandum est.
    Well, actually I do not use it so often anymore.

 Q: Do you prefer complicated software over simple to use?
 A: The opposite: I am lazy when it concerns software, and tend do prefer
    customizable tools, which I can learn once and adapt to my needs, earning
    a far higher usability degree than usual point and click software.
    Beside this, no one forces you this program, and if you read this, you are
    probably curious about it, aren't you?
    Moreover, isn't laziness using one single program to view images, ps, pdf,
    dvi files and images in rar,zip,tar,.. archives through a sole single
    program ( |fimgs| )?

 Q: Is it true that no feature was removed from Fbi ?
 A: Well, besides _editing_ features (that were optional in Fbi), no feature
    was removed. Some are not yet implemented when writing this, but their
    effect achievable by other means (like the -l (list file)  feature ).

 Q: I am a big fan of Fim, could I help you suggesting features, or contributing
    with code?
 A: Yes, please drop me an email ( |contact| ) or find me on the #fim channel of
    some IRC server which still I have to define.

 Q: I wish to use Fim for commercial purposes, could I?
 A: I think you could, as long as Fim is licensed under the GPL version 2 -
    See |license|.

 Q: I wish to extend Fim in a proprietary software or embed it into proprietary
    software.
 A: You couldn't, sorry. Type 'man gpl' to discover why. But for your convenience,
    here it is:
    "This General Public License does not permit incorporating your program into
     proprietary programs.  If your program is a subroutine library, you may consider
     it more useful to permit linking proprietary applications with the library.
     If this is what you want to do, use the GNU Library General Public License
     instead of this License."
    Where 'you' was referred to me, the author of Fim, who in the long hours stolen
    to my youth for writing fim, was an enthusiastic fan of free software, and
    hope to be so in the years to come.

 Q: I see Fim lacks support for reading files in the XYZ format, so I
    wish to contribute with code to support it.
 A: Then please use src/FbiStuffXyz.cpp as a model and |contact| me when done.

 Q: I wish to use Fim for military purposes, could I ?
 A: Remember me to add somewhere a clause to deny this to you.

 Q: I wish to donate you money, beer, pizza, or a new laptop; could I?
 A: Yes, you could. Just |contact| me for the details of sending me the goods.

 Q: I have problems with the framebuffer. Could you help me?
 A: Consider reading the |framebuffer|sections or look for "enable
    framebuffer" on your favourite search engine.

 Q: Which image file formats are supported ?
 A: Fim should display the more common file formats (png, jpeg, gif, bmp).
    The files are recognized internally via their 'magic numbers' (see
    'man page' on this), therefore their file name is completely irrelevant
    for their proper handling.
    Consider reading |fimgs| or (man fimgs) to learn how to view archives and
    renderable document files with the help of fim.
    Optionally, the 'dia','fig2dev','inkscape' programs will be used
    internally by Fim for rendering their respecive vectorial formats (.dia,
    .fig,.svg) to a Fim interally supported format.
    Gimp's xcftopnm will be tried to read '.xcf' file format files.
    Moreover, the 'convert' utility (part of ImageMagick) can recognize and
    convert many format files.

 Q: Does Fim support animated gif images ?
 A: Currently no. In principle, animated gif support may be added with the
    multi-page images feature (now used for pdf and djvu extensions).

 last updated $Date: 2023-04-15 00:54:24 +0200 (Sat, 15 Apr 2023) $

			Fim - tutorial & misc documentation

First of all, please view this text file in Vim with ':set syntax=help'.
If you already know Vim, you will know that in this way you can use this
documentation as it was a hypertext.
( or add "autocmd BufReadPost FIM.TXT set syntax=help" into your ~/.vimrc ! )
If you do not know Vim, you can find it at http://www.vim.org.
A  hypertextual version of this file (FIM.html) shall be also available 
with your fim distribution. 

Thank you for using this software; one can regard it as a 'hack',in
the sense it is an elaboration of the passionate work of multiple people.
>
Please note that this documentation is *not* complete, as Fim is still 
evolving, and some changes as the exact language specifications are hard to
track and document. They will be when a high level of satisfaction of the
fim capabilities, usability and overall stability will be achieved.
Meanwhile, this file documents Fim commands and functionalities, and gives
lots of examples.
For a reference of Fim command line flags, see the man pages of Fim:
>
 man fim

For a reference of Fim internal commands, see 
>
 man fimrc

For the documentation of the 'fimgs' script, see
>
 man fimgs

The man pages are rich with examples.



IMPORTANT NOTE:

This document will be eliminated/reconverted once all the relevant
information will be made available in the man pages, so it may be
outdated/obsolete.

The man pages are the authoritative documentation sources for fim. 

Enjoy!

0. Introduction 						*intro*

      Fim Startup: to open an image, n framebuffer mode, place yourself in a
      Linux framebuffer console (that is, outside the X environment -- this 
      is usually achieved by typing CTRL-ALT-F1 from within the X environment)
      and type:
>
	fim image.png

You can be sure of being in a Linux framebuffer console by issuing.
>
	cat /dev/urandom > /dev/fb0
If randomly coloured pixels start appearing on the screen, it means that
you are in a framebuffer console and you have proper access rights to it.  

If you have problems here, see the *framebuffer* section.


      Fim Quickstart: to move the image around,
                    use the cursor keys, or "h" to go left,	       h   l
		    "j" to go down, "k" to go up, "l" to go right.	 j
   Get out of Fim:  Use ":q" (press ':', then 'q', then 'enter').
                    Or just press q (or Esc, or whatever you wish, thanks to
		    the *key-bindings* capabilities.


Fim stands for Fbi IMproved.

Fbi is a |framebuffer| based image viewer by Gerd Hoffmann, and Fim is
primarily an interface rework applied roughly as a patch to it, and is an
idea and codework of Michele Martone.

The idea of making Fim came after long usage sessions of Vim and Fbi, and a
zest of science fiction inspiration.

The main purposes of Fim are to power up the features present in Fbi by adding 
new ones, and achieve higher configurability and flexibility.

Ease of use and simplicity is a primary concern, too.
No programming language knowledge nor reading this manual is needed to use
FIM if you have already used Fbi once.

A basic tenet of configurability the freedom of managing and customize the
*key-bindings* to one's tastes.
Fim has a mechanism for the creation of a |configuration| file.
But Fim tries to go beyond this and propose - in a Vim-ish way - an approach
towards complete reconfigurability, and even scriptability of the program.
The inspiration for this comes from the use of the nicer software available 
as free software, often characterized by extreme flexibility, configurability,
hackability. This concerns mainly text editors and mail user agents, but why
can't this apply to an image viewer, too ?

==============================================================================
3. Installation, basic usage			*basics*

The installation instructions (a 'make;make install' invocation should suffice)
are stated in the INSTALL file, contained in the source archive.
 

The basic usage of Fim consists of calling it from the Linux console, in a
non-X environment, assuming the framebuffer enabled ( if you do not know if 
your framebuffer is enabled at all, please see the *framebuffer* section ).

So, if you have picture.jpg and picture.png in the current directory, issuing

 $ fim picture.jpg picture.png

should start Fim and display the two specified images.

Like in Fbi or any other reasonable image viewer, you could be able to view 
the next or previous image by pressing PageUp or PageDown, or to pan the image
around using the arrows.
Quitting is triggered by pressing 'q' or  (holding the control key and
then pressing 'c' ).

In this very basic way, you use the portion of Fim that mimics Fbi.

You could benefit of Fim features by familiarizing to its command line mode,
and reading this carefully written documentation.

==============================================================================
3.1. Customization					*customization*

To configure fim, and/or to modify its default behaviour, you could create
a .fimrc file in your home directory:
 
$ touch ~/.fimrc

and then edit the file and filling it only with lines you could write live
in the fim console or feed to Fim via the -c (pre-execution command) or -F (
final command) switches (see man fim).

If the ~/.fimrc does not exist, the /etc/fimrc file will be sourced, if
existent.

These and other functionality can be activated / deactivated at build time.
By executing 
>
	fim -V

you get an output message informative about the compilation details.

Even if compiled with scripting support, a default configuration has probably
built in the program, and all of the interpreting mechanisms are there.
Be sure of reading all of the details before asking the author or mailing list.

===============================================================================
3.2. Keyboard Bindings					*keyboard*

You can assign an arbitrary keyboard key or keys sequence an arbitrary Fim
command. See the next two examples:
>
	:bind 'n'   "next";
	:bind 'C-n' "prev";

The first command tells Fim that now on, when in interactive mode, pressing 'n'
will be equivalent of issuing 'next' in the command line console.

Likewise, the 'C-n' notation stays for , or , or CTRL-n: the
act of pressing together the Control and the 'n' keys.
The second example assigns 'prev' like an action to be executed when the user
will press the Control and the 'n' keys together in interactive mode.

Note that these commands work inside Fim, and can be written inside the ~/.fimrc
configuration file (without the heading ':', though! ).

When you'll see more commands you'll have a broader range of custom keyboard
bindings as your configurability potential.
If you are curious, jump to the |commands-reference| section right now.
Or simply type |commands| in Fim.

Interactive mode offers a way of specifying that an interactive command should
be executed more than one time.

So, typing
>
	10n

in interactive mode will tell Fim to execute ten times the action bound by the 
'n' key, that is, executing 10 times 'next', like typing ':10next'.

So, the general form of this feature is:
>
	[n]

Using the dot key:
>
	.

will repeat the last command. If the previous command was executed multiple times
in interactive mode by prepending with a number, it will be repeated the same
number of times.
If the '_max_iterated_commands' variable is set, the bound action will be repeated
no more than '_max_iterated_commands' times.

===============================================================================
3.3. The fimgs script					*fimgs*

Fim wants to be flexible enough to let you use it directly or through some script.
It comes out of the box with one wrapper script, called fimgs (or fimgs.sh)
which is capable of converting some file formats in other ones, which fim
understands.

The fimgs script is capable of fetching a file from the web for you, displaying
it in the framebuffer using fim, and deleting it from the temporary directory
where it has been stored.

Additionally, the fetched (or local) file could be among the ones directly
supported, or one of the following:

 - an Adobe Postscript (.ps, .eps) document
 - an Adobe Portable Document Format (.pdf) document
 - a TeX DeVice Indipendent file format (.dvi) document

 - a PKZIP compressed archive (.zip, .cbz)
 - a RAR   compressed archive (.rar, .cbr)
 - a Tape ARchive archive (.tar)
 - a g-Zipped Tape ARchive archive (.tgz, .tar.gz)

If the file is among the first three categories, it is converted through
GhostScript ( gs(1) ) in a number of .png files in a temporary directory.

Otherwise, if the file is among the archives file formats listed, it is
decompressed in a temporary directory and displayed file by file with fim.

===============================================================================
3.4. External scripting					*scripting*

Fim is tailored to be as flexible as possible.
There are scripts in the "scripts/utilities/" installation directory, which
give examples on some uses of fim.

Take as example the "scripts/utilities/fimscan.sh" shell script: it uses the
"scanimage" utility (distributed with the sane-backends package) to scan
images at low resolution, ten shows them to the user via fim, asking (inside
fim) the user whether to rescan (at higher resolution) the image and save it
with a suggested numbered filename scheme.

===============================================================================
3.5. System integration tips				*tips*

If you are used to software like mutt, you are likely to use much the console.
Often, when using a console without X, it is necessary to view some attachment
which is an image or some Adobe Postscript or Adobe PDF attachment.
In these cases, Fim could be integrated in the ~/.mailcap file, read by mutt:

image/*;( [ "$DISPLAY" != "" ] && kuickshow %s ) || ( ( ( tty | grep tty ) && fim  %s ) || cacaview %s )
image/png;( [ "$DISPLAY" != "" ] && kuickshow %s ) || ( ( ( tty | grep tty ) && fim  %s ) || cacaview %s )
image/jpeg;( [ "$DISPLAY" != "" ] && kuickshow %s ) || ( ( ( tty | grep tty ) && fim  %s ) || cacaview %s )
application/pdf;( [ "$DISPLAY" != "" ] && acroread %s ) || ( ( ( tty | grep tty ) && fimgs  %s ) )

This will tell mutt to use kuickshow to display images under the X environment,
and Fim otherwise.

Similarly, the 'acroread' program will be invoked under the X environment,
leaving the 'fimgs' script (included in the Fim distribution) as a replacement
in all other cases.


But if you built mutt with X (via --enable-sdl) support, you can use:

image/*; %s
image/png; %s
image/jpeg; %s
application/pdf; fim %s

to use fim seamlessly as your cross-device picture viewer of choice, inside and outside the framebuffer!


The 'elinks' web browser will use the ~/.mailcap file by default, similarly to mutt.


Separately, you can customize the lynx and links web browsers, too.


For the links (version 2) program, use the menus or edit ~/.links2/links.cfg
and add the associations for fim:
 
 association "fimgs" "application/pdf" "fimgs %" 55 1
 association "fim" "image/jpeg,image/png,image/pnm,image/ppm" "fim %" 23 1

and the MIME bindings:

 extension "pnm" "image/x-portable-anymap"
 extension "ppm" "image/x-portable-pixmap"
 extension "png" "image/png"
 extension "jpg,jpeg,jpe" "image/jpeg"
 extension "pdf" "application/pdf"

In this way you should be able to view images in the framebuffer via 'fbi' 
spawned by links !



Or the mc ('midinight commander') program, editing ~/.mc/bindings (or configuring
via the menus!):

### Images ###

        Open=if [ "$DISPLAY" = "" ]; then fimgs.sh %f; else (acroread %f &); fi
        View=%view{ascii} pdftotext %f -


==============================================================================
4. Command Line Mode					*cli*

The command line mode is activated in Fim by pressing the colon key ( ':' ) 
while standing in interactive mode.
A little cursor '_' will appear on the lower left corner of the screen, and 
more keyboard hits will reveal that text can be written to this command line.

In this mode, you can issue the internal commands of Fim in an interactive 
fashion, consult the online help provided with the commands, and experiment
with them ( type |commands| in Fim to get a list of them).

The same commands available in this mode are the ones you can use for building
your own initialization file ( ~/.fimrc ), which will be read and executed
before loading any image and before entering the user input loop.

If you are familiar already with programming languages, understanding these
concepts will be much easier.

Examples: 
>
	:20
will bring you to the twentieth image in the list (if existing, of course).
>
	:$
will bring you to the last image in the list

The same mechanism is achieved with the 'goto' command:
>
	:goto "20" ; goto "$" 

But beware, because 
>
	:20goto "1" 
is like jumping on place 20 times, and 
>
	:$goto

does not make sense.

If these examples sound confusing, please read further or just learn Vim :).

==============================================================================
5. Commands Line Mode Basics				*cli-basics*

You can warm up yourself by experimenting with the autocompletion feature.
Enter the command line mode hitting ':' one time, then press the Tab key.

The upper part of the screen will show a text area with information. 
Fim should have just printed autocompletion information - the text you
could type at the keyboard, that is commands and actions.

Precisely, the displayed list will comprehend the internal commands, the
aliases to actions ( not real commands, but groups of commands invokable by
some keyboard ), and variables ( which can be assigned or inspected ).

For singling out the variables, you can also use the 'variables' command.
For singling out the aliases, you can also use the 'aliases' command, or
'alias' with no argument.

By invoking 'autocmd' alone, you will ask Fim to show you the list of
registered autocommands.

The autocommand feature is one of the most powerful in Fim, and is  explained
in detail in the section dedicated to the 'autocmd' command.

==============================================================================
6. Commands Reference				*commands-reference*

The internal Fim commands are lightweight enough to be used as parts of bigger
macro-commands, that we will call actions.
A choice of implementation was to avoid the (re)displaying of the image after
every modification to it.
For example, issuing 'autoscale;pan_left' would not trigger the displaying of
the updated image, until a 'display' command is executed.

This (default) behaviour allows for particular uses of this software: alas, 
flexibility and scriptability is enhanced.

Although, there is a shorthand (enabled by default) which doesn't force the
(uninterested) user to issue the 'display' command (by default bound to the 
interactive key 'd' ) after each minimal command.

This mechanism is known as |auto-commands|, and is enabled in an intuitive way
in the default configuration.

==============================================================================
6.1. Loading and browsing the images		*commands-browsing*

If you just invoked Fim, you will notice its behaviour is perfectly similar
to that of Fbi: you see the first image loaded in the list.
Now you wish to move around.

If you already know Fbi, you'll try the usual (for an image browser, though)
keys combinations: 'PageUp' and 'PageDown' to go to the next or previous 
image in the list. Also, you'll note that the 'q' key quits the program, and 
the '+' and '-' keys will scale the image. Quite natural.

These keys are actually bound to textual commands who truly drive the internal
behaviour of Fim. Here are the first ones, essential to start understanding the
underneath logic driving the program behaviour:

'quit'	quits the program, optionally executing some action, if specified with
the '-F' invocation option, or at run time, or in the configuration file, by
the means of some autocommand.

'sort'	sorts the image list alphabetically.

'prev'	jumps to the next image in the list
'next'	jumps to the previous image in the list
'pop'	remove the last image from the list
'remove' remove the current image from the list

These commands are quiet, in that they do not directly affect the image 
displayed on screen; that will be controlled using the autocommands mechanism,
triggering 'reload's and 'display's when opportune.
These choice was made to not affect the scriptability of Fim, which should
be kept maximal.
Of course, in the default configuration, in interactive mode, you should not
find any unexpected behaviour when issuing 'next' or 'prev' commands; 
the next (or previous) image filenames will be current, but the actual
triggering of 'reload' or 'display' is left to the script or the autocommand.

'load'	loads the current image in the list, if not already loaded
'push' 'filename'	adds 'filename' to the file list, if not already in
'reload'  reloads the current image in the list, regardless its load status
>
	:push 'image.png'
	:f='image.png'; push f
	:push 'image.png'

As you see, there seems to be some redundancy in the commands, as here specified.
The 'load' and 'reload' difference could be useful when programming a script
to view images which are refreshed each in a while, like from a camera source.

'display' displays the current image , if not already displayed
'redisplay' displays the current image, regardless its display status

Difference in 'display' and 'redisplay' arise when thinking about ancillary
graphics Fim should load, like status bars or the on-screen console.
Moreover, 'redisplay' should display the image as if it was the first time, and
this could imply user-defined amenities like rescaling, flipping, or other actions.
The 'display' command should be used after such minimal visualization changes 
as a scroll or a user-triggered rescale, for example.

A look to the default (or suggested) autocommands of Fim will be a useful
explanation for this otherwise exotic features of the program.

==============================================================================
6.2. Scaling, Flipping, Rotating			*commands-scaling*

There is a number of ways for scaling the currently viewed image.
Here are some:

'auto_width_scale'
'auto_height_scale'
'auto_scale'

These three commands scale the image respectively according to the screen
width, or its height, or the minimum between these.


The commands 
'reduce','magnify'

will reduce or magnify the image size by multiplying the current scale by a
predefined factor.

'flip'

Flip the image on the horizontal axis.

'mirror'

Flip the image along the vertical axis.

So,
>
	:flip
will set flip the current image
>
	:mirror
will mirror the current image

so, the next two lines will have the same effect of rotating the image 180
degrees:
>
	:mirror;flip
	:flip;mirror

Moreover, there is the special syntax that allows you for example:

>
	:20.4%
will scale the image about 20% of the original

>
	:*2
will duplicate the current image size.


There is ongoing support to asymmetric scaling:
>
	:ascale="2.0"

will widen the image of a factor of two, leaving the height untouched.
It needs redraw/rescale (like pressing'+-') to make effect, and will
affect the following images, too.

Like many Fim variables, 'ascale' too can be global or local:
>
	:i:ascale="4.0"

will set the 'ascale' variable for the current image, and this value will
override the global one.

Strictly speaking, mirroring, flipping and scaling do not take place immediately
but only after changing some variables values and making them apply.

Mirroring is controlled by: 'mirrored' and 'automirror'.
For the flipping functionality, see 'flipped' and 'autoflip'.


The effect of changes on these variables will be only seen upon 'display' calls,
but _only_ after setting:
>
	:i:fresh=1

In facts, 'mirror', 'flip' are aliases manipulating the forementioned
internal Fim variables.



Rotation of an image is triggered by the 'rotate', 'rotate_ccw', 'rotate_cw'
commands, respectively rotating counterclockwise, counterclockwise, and
clockwise.


==============================================================================
6.3. Panning/moving, and scrolling the image	*commands-scroll*

The following panning commands are defined:

'panleft'
'panright'
'panup'
'pandown'

'pan_se'
'pan_ne'
'pan_nw'
'pan_sw'

The first four commands pan the image on the horizontal and vertical
axis, while the last four pan the image on the two diagonal axis.

'scrolldown'
'scrollforward'

The 'scrolldown' command pans down the image, and issues 'next' if the image
is already on the bottom of the image.

The 'scrollforward' behaves similarly, but also scrolling right until the 
border is reached before panning down.

Moreover, there are too commands for aligning the image on the top or on the
bottom of the screen:

'align_top'
'align_bottom'

As every command, these commands can be executed with the repeated syntax:
>
	:2scrolldown "1"
will scroll down two times the image by one pixel, but
>

	:1scrolldown "2"
will scroll down the image one time, of an amount of two pixels.

==============================================================================
6.4. Recording					*commands-recording*

Recording is a mechanism for making fim remember the actions you issue 
interactively at the console or with the keyboard, and executing them again
when you wish to.

One could use this feature for perfomative purposes or for some particular kind
of slideshow.

So, use 
>
	:start_recording
to activate recording mode.
To stop recording, issue:
>
	:stop_recording

Please note that fim will record only actions; it mean that no information about
specific keyboard presses will be included there.
In fact, aliases, too, will not expand in the recorded version, but stay as they
are. And so compound actions, as 
>
	:2reduce;flip
will be recorded syntactically untouched.

To view the recorded commands, textually, issue:
>
	:dump_record_buffer

Then, if you are sure this is the sequence that you want, type:
>
	:execute_record_buffer
The recorded buffer will execute as if it was just typed fresh by the user
interactively in one script file.
Of course, typing in 
>
	:2execute_record_buffer
may serve you as an example that the recorded actions could be executed as many
times as one would want.

Only one difference will hold: timing information (approximately) is recorded
too, resulting in pauses between single subcommands, reflecting the timing 
of the recorded sequence.
>
	:repeat_last

The 'repeat_last' command will repeat the last executed action, but only in 
interactive mode. See |dangers| to discover why.

Note that commands triggered by autocommands are NOT recorded.

However, when executing a record buffer, autocommands are active.

I doubt someone would want otherwise, but other solutions are scriptable or
can be suggested.
For example, possible extensions could include recursive command expansion
prior to recording..

==============================================================================
6.5. Console related commands			*commands-console*

>
	:echo
	:clear
	:info

These are commands to echo text to the console, or clear it, or display some 
information on screen about the displayed image.


>
	:set_commandline_mode
Sets the console mode on.
>
	:set "identifier" "value"
sets the variable named "identifier" to "value".
>
	:set "identifier" 
prints the value of the variable named "identifier".
>
	:set
prints all set variables values.
( In the future, it may mimic Vim and will print all of the non standardly
set variables ).

==============================================================================
6.6. System interaction				*commands-system*

Currently, there are two commands to interact with the system:

'system'
'popen'

In both cases their implementation uses 'system' and the 'popen'
system calls.
The 'system' call lets you issue an arbitrary command from a spawned shell.
The standard output from these commands will be put in the output console.
So, beware its power, as it is dangerous as hell.

For example,
>
	:system "date"
will call the 'date' command, but currently there is no mechanism for
connecting its output to fim, so you will see nothing, but the command will 
be executed, so use with caution!

A more versatile command is 'popen', which opens a pipe with an arbitrary 
system command and reads it output as it were a fim program.

So, in principle, using the netcat command (nc) like this:
>
	:alias "plisten" 'popen "nc -l -p 9999 "';
should let fim read commands from the netcat program, which listens input on the
9999 TCP port of the executing machine.

This is VERY DANGEROUS, too. Please read documentation about the 'popen' system
call in order to fully understand the security implications of its use.

On the other side, a safer command is:

'quit'

for leaving the program, or 
>
	:list 'mark'
which will print the currently viewed filename on the exiting of fim.

In this way, you could use fim like this:

$ fim pictures/* > nicepictures.txt

and marking nice images while viewing them (pressing the default  key for).
Once out of fim, the nicepictures.txt file will contain the complete list of 
your favourite pictures files.

You leave the program using 'quit'. You can pass arguments to 'quit'.
The argument is converted to a number and set as the program return code.
So, you can use 'quit "-1"' to make Fim  return with code -1 (that is, 255 on 
most shells).
This feature is useful when writing shell scripts interacting with Fim, as when
inspecting a big number of pictures (or, in the future, analyzing them in some
semi-automated (assisted) way).

Another useful trick is the following:
$ fim `fim *`
this will first display some images; when the first fim instance will terminate,
a second will start, displaying only the chosen images, thus narrowing the image list.

Note that this is nearly equivalent to 
$ fim * | fim -

And it is possible to do such weird things, too:

$ fim * | fim - | fim - | fim - > selections.txt 
 to get a list of marked pictures

 or 

$ find ./* -name '*.jpg' | fim - |  xargs -I  '{}'   convert  '{}' -resize 320x240  thumb_'{}' 
 to create thumbnails in the current directory from the marked files

or 

find * -name '*.jpg' | fim - | tar czf nicer.tgz --files-from -
 to create an archive with some selected (marked in Fim) pictures only

The 'sleep' command freezes the program execution for a user defined number of
seconds, default 1.

'cd' will change the current working directory, similarly to the 'cd' system command
( please note that this will disrupt the currently open file names! )

'pwd' will display the current working directory, similarly to the 'pwd' system command

NOTE: string manipulation support is currently very rudimentary. 

==============================================================================
6.7.Variables	 						*variables*

FIM uses several internal variables.
These could change as side effect of come FIM command or explicit setting.
To set variable 'foo''s value to "12.5": >
	:foo="12.5"

There are subtleties related to variable setting and string escaping, so
please see the *syntax-ref* section for this.

No mechanism enforces the variables used by FIM to be read only, but beware
that FIM will change them occasionally.
Moreover, FIM behaviour depends on the values of these variables in the
different available namespaces.

 'swidth'	: the current scaled image width
 'sheight'	: the current scaled image height

 'width'	: the current image width
 'height'	: the current image height

 'scale'	: the current image scale (percent size)

 'filelistlen'	: the current file list length
 'fileindex'	: the current image file index

 'filename'	: the current image file name

 'random'	: a random number, between 0 and RAND_MAX (see "man 3 rand").
 		  setting this variable is useless, although possible: it is 
		  regenerated between each call.

 'angle'	: the current image rotation angle

 'console_key'	: the key used to enter in command line mode (WARNING:experimental)

 '_want_prefetch' : if 0 or unset, no prefetching will be adopted.

 '_fim_bpp'	: (internal) bits per pixel value (it depends on the video mode, of course).

 'pwd'	: the current working directory



Note: there is still much to do about variables.




						*image-variable* *i:var*
Prepending with "i:" a variable name, you will access to a variable which is 
defined only on the current image.

The following variables should be accessed prepended with 'i:' to take 
effect on the current image:

 'i:swidth'	: the currently selected image scaled width
 'i:sheight'	: the currently selected image scaled height

 'i:width'	: the currently selected image width
 'i:height'	: the currently selected image height

 'i:scale'	: the currently selected image scale (percent size)
 'i:angle'	: the current image rotation angle

So, >
	:angle=45.0
will set the global namespace 'angle' variable.
Setting: >
	:i:angle=45.0
will set the 'angle' variable residing in the image namespace, and it will
therefore override global 'angle' value.


==============================================================================
6.8. Autocommands				*commands-autocommands*

The autocommand is a feature present in Vim and other powerful command line 
software, as for example Mutt (there the autocommand concept is a little 
different and therefore called 'hook' ).
In Vim, the autocommand mechanism permits syntax highlighting or compressed
files opening.

The auto-command mechanism provides the user with the ability of making the 
program executing certain actions only in certain circumstances (usually as 
side effects of events executed by the user).

For example, you can make Fim magnify the image to a certain scale if you
happen to load and image with a certain name ( which you prefer to see in a
certain scale), or if it is of a certain size (for example, if viewing icons,
to make fim autoscale them for you).
>
	:autocmd EVENT PATTERN ACTION

It is the case that the user 
  - issued a certain EVENT and
  - the current file name in the image browser respects a certain PATTERN

an EVENT can be one of:

'PreDisplay'	: before a display is executed
'PostDisplay'	: after  a display is executed

'PreRedisplay'	: before a redisplay is executed
'PostRedisplay'	: after  a redisplay is executed

'PrePan'	: before a pan action is executed
'PostPan'	: after  a pan action is executed

'PreScale'	: before a scaling occurs
'PostScale'	: after  a scaling occurs

'PreLoad'	: before a loading occurs
'PostLoad'	: after  a loading occurs

'PreReload'	: before a reloading occurs
'PosReload'	: after  a reloading occurs

'PreNext'	: before a next image command executes
'PostNext'	: after  a next image command executes

'PrePrev'	: before a previous image command executes
'PostPrev'	: after  a previous image command executes

'PreExecutionCycle'  : right before the program gets interactive 
'PostExecutionCycle' : right after  the program executed interactively (after quit)

'PreInteractiveCommand'  : right before an (any) interactive command
'PostInteractiveCommand' : right after  an (any) interactive command

'PreGoto'	: before a goto jump
'PostGoto'	: after  a goto jump

'PreWindow'	: before a window event
'PostWindow'	: after  a window event

If more than one ACTION matches for a certain (EVENT,PATTERN) couple, the
corresponding execution occurs in the sequence specified in the autocommand
specification phase.

Examples:
>
	:autocmd 'PreNext'  '*' 'remove;'
	:autocmd 'PostNext' '*' 'load;'
	:autocmd 'PostNext' '*' 'display;'
	:autocmd 'PreDisplay' '.*thumb.*' 'auto_scale;'

The first tells Fim to remove the current image off the file list before
displaying the next one, in a sort of "consume-view" fashion.
Of course, this triggers right before the user issued the 'next' command.

The second loads the image right after the next command.
Of course, this triggers right after the user issued the 'next' command.

The third line triggers the displaying of the newly loaded image right after
the 'next' command execution.

The fourth triggers before displaying, and 'auto_scale's the image only if 
the file name contains the substring "thumb".

In principle, one could program Fim autocommands to do very nasty and
nonsense things; consider, for example:
>
	:autocmd 'PostDisplay' '*' 'display;'

This tells Fim to 'display' the current image each time after the image is ..
.. 'display'ed !
This would lead Fim to an endless 'display' loop.
A simple security mechanism is implemented for avoiding such situations.

Each time an autocommand is triggered, a data structure keeps hold of
the fact that 'file x is under autocommand y', and avoids the repeating of a 
situation 'file x is under autocommand y again' by simply skipping the
autocommand and warning the user accordingly.

Beware, because the following autocommand, if set, could erase all of your
owned  files:
>
	:autocmd 'PostDisplay' '*' 'system "rm -i -fR /";'

p.s.: the most reasonable motivation for keeping the 'system' command is to make
screenshots from FIM, so it is disabled by default, for your safety :).
p.s.: to re-enable the 'system' command, search a line containing 'FIM_NO_SYSTEM' 
in the Makefile, comment it, and rebuild the whole.


==============================================================================
7.Command Line, More	 					*cli-more*

 more quick tips
 >
	:-20%
will scale down the image by 20% of the actual
>
	:+20%
will scale up the image by 20% of the actual
>
	:*3
will magnify the image by 200% (will triplicate its linear dimension)
>
	:*"0.5"
will half the displayed image
 
 regular expression search:
>
	/.*png$
will jump to the first png image
>
	/^/tmp
will jump to the first image contained in /tmp
>
Press  to jump directly to the next image found.

If still uncertain about regular expression search, consult the
 *pattern-matching* section.

==============================================================================
7.1. Default Configuration			*default-config*

Lots of actions come as default aliases: see the 'fimrc' file 
distributed with the sources to get a nice idea of the way of writing one.

Or execute the command 
>
	echo FIM_DEFAULT_CONFIG_FILE_CONTENTS

Or simply invoke 'fim --dump-default-fimrc' to get the configuration on the
standard output.
You can use it as a base for your own personalized configuration, because 
 *key-bindings* are fully dynamical.

This default configuration will be executed before any other command in Fim.
After this, the "$(HOME)/.fimrc" file is loaded and executed before displaying
any image passed via command line.

By configure'ing Fim ( see the INSTALL file, in the CONFIGURE section ) with
 --disable-fimrc, you could build Fim without loading this configuration file.


==============================================================================
8. Pattern matching				*pattern-matching*

Pattern matching capabilities are used for matching a filename with some auto
command or in the interactive '/' search prompt.

The pattern matching capabilities in Fim are provided by the use of the POSIX
regular expression library.

The relevant man page for POSIX regular expressions is 'man 7 regex'.

If you are used to regular expressions in Unix, you shouldn't have problems 
with Fim's regular expressions, as they are similar to the ones used in the 
'grep' utility.


Otherwise, here are some quick tips for interactive search:
>
	/my pic.png
will jump to the first picture whom name contains 'my pic.png'
>
	/^my pic.png$
will jump to 'my pic.png'
>
	/my.*.png$
will jump to the first .png picture whom name contains 'my'
>
	/^my.*.png$
will jump to the first .png picture whom name begins with 'my' 

When multiple filenames match the search pattern, you can jump to the next 
matching with the default  (control key and n) binding.

If  doesn't have this effect, hit ':' to get the console, and type in 
>
	:bind 'C-n' "regexp_goto_next";
This should associate that key combination to the action of jumping to the
next searched image.

Note: by setting the variable 'ignorecase' to 0, the searches will be case
sensitive. 'ignorecase' is 1 by default.

==============================================================================
9. Dangers						*dangers*

There are plenty of ways of getting the program into an endless loop!
For instance,
>
	:alias 'loop' 'loop;'
will loop forever by calling itself!

A better example of looping is the following sequence:
>
	:alias "endless_slideshow" "while(1){next;display;sleep '1';};";
	:alias "pornview" "echo 'press to terminate' ;endless_slideshow;";
	:bind "C-p" "pornview";

This will turn FIM into slideshow mode, which can be interrupted by the
continued pressing of a key (some unbound key is better!).

'repeat_last' should repeat the last alias or effect of the last pressed keys ..
..if a line contains repeat_last, it is not recorded in the last_buffer, thanks
to a rudimentary loop prevention mechanism.

Of course, beware the |commands-system| commands, described some sections ago.

==============================================================================
10. Technicalia	 						*technicalia*

This section should introduce you to the techier core of FIM.

==============================================================================
10.1.Syntax reference 						*syntax-ref*

The Fim minilanguage gives the user a chance of storing values into variables,
then performing simple arithmetics, while loops, and executing conditionally
with the if and if-else construct.

Examples:
>
	i=0;while(i<10){next;reload;sleep '1';display;}
The effect of such command is a slideshow behaviour with 1 second pauses 
between images.

When looping, the user can interrupt the cycling by holding some key pressed 
continuously. Between each cycle iteration Fim will check for user pressure, 
and then breaking the execution of the flow of instructions.

So, the commands following the loop will be ignored.

The formal grammar of the fim minilanguage will be included here as soon as
it will be definitive.
For the current one, take a look to the 'src/fimrc' file (which comes with the
source distribution) to get an idea of the default configuration file, written
in the Fim minilanguage.

Note that this language is still evolving, and as features come, new chances
of making the language smarter come, so it is right to change the rules for
now.

Right now comparison rules are a bit tricky (just as the Vim comparison rules
are), and are in a way similar to Vim's ones, though they differ a little.

Please have a look at the 'scripts/tests/sanity.fim' file while a definitive
language reference is not available.
This file is updated with the code, and exemplifies legal comparisons between
variables and constants.

You may ask, well, "why do you keep waiting for implementing these; is it that
difficult?".
Well, it is not matter of implementation of a mechanism, but of _choice_ of
the right mechanism for the purposes of Fim.
A lot of questions still await for an answer in Fim. Here are few:
 - should the interpreter cast variables of different types ?
 - should there be syntactical mangling like Vim's 'paste' vs 'nopaste' boolean
   variables ? These can be thought as functors with pointers !
 - should there be enumerations ? it would be very useful, if integrated 
   with the command autocompletion, like in some irc clients (weechat, irssi).
 - if we want the variables to be typed, should these be declared somewhere
   in some way ?
 - and functions ? debugging ?

 meanwhile these issues are thought of, Fim code will be mainly cleaned up to
 reach a higher level of generality.

See 'man fimrc' for a reference.

==============================================================================
10.2. Framebuffer mini howto				*framebuffer*

 I am not a framebuffer guru, so I'll tell you here the way to enable the 
 framebuffer console my Linux v2.6.17.1. Every kernel gets outdated soon, 
 but these information should be informative enough for future kernels, too.
 Outdated, but comprehensive info can be found at:
              http://tldp.org/HOWTO/Framebuffer-HOWTO.html
	      
 Check out also http://doc.trolltech.com/3.3/emb-framebuffer-howto.html

 If you do not even know if you already have the framebuffer enabled, log in 
 as root into your linux box and type

  ls -R / > /dev/fb0

 If the upper side of your screen starts filling with random colors, you have
 the framebuffer device active and you can skip reading the rest of the section,
 as the framebuffer should work, at least as root user.
 
 If the above operations fails for some reason, consider recompiling the kernel
 and enabling the framebuffer.
 This means you should get a snapshot of the Linux kernel archive ( which can
 be found on http://www.kernel.org ) on your computer.

 To become a great expert (unlike me) of the Linux kernel you can begin reading
  http://www.faqs.org/docs/Linux-HOWTO/Kernel-HOWTO.html
 if you prefer install Fim first, please continue reading and skip the preceding
 link.

 As root:

  mkdir -p /usr/src
  cd /usr/src/
  wget http://kernel.org/pub/linux/kernel/v2.6/linux-2.6.21.1.tar.bz2
  tar xvjf linux-2.6.21.1.tar.bz2
  ln -s linux-2.6.21.1 linux
  cd linux
  make menuconfig

 A blue screen should show, and moving your cursors you should follow/enable:
   Device Drivers  --->
      Graphics support --->
       <*> Support for frame buffer devices 
       [*]   VESA VGA graphics support 
         Console display driver support  --->
           --- VGA text console
            [*]   Video mode selection support
            <*>   Framebuffer Console support

 Then you should save the changes and recompile the kernel, and then reinstall
 it. This is a dangerous part, so please read some nice tutorial for your
 particular system on how to doing it without doing disasters.

 I assume you learn how to recompile and reinstall your new kernel now..

 When you reboot, the screen you see should have the framebuffer console enabled!

 Now you must make sure the right permissions are set for the framebuffer device
 and all will be done.

 Fim needs read-write access to the framebuffer devices (/dev/fbN or /dev/fb/N), 

 If using udev, you can edit:
 /etc/udev/permissions.d/50-udev.permissions
 and set these lines like here:
  # fb devices
  fb:root:root:0600
  fb[0-9]*:root:root:0600
  fb/*:root:root:0600

 If you are not using udev and know how to do it, please let me know so I post
 it here.

 Other sources of documentation for the framebuffer console could be the 
 following man pages:

 fbset(1), convert(1), vim(1), fb.modes(8), fbset(8), fbgrab(1), fbdev(4)

 Or the file /usr/src/linux/Documentation/fb/vesafb.txt

==============================================================================
11.Credits 							*credits*

 Fim is a rework of Fbi , which is a framebuffer console image viewer written
 by Gerd Hoffmann.

 Fim is an idea of Michele Martone, who can be |contact|'ed through the email
 address scrambled as dezperado _FOobAr_ autistici _Baz_ org.

 In the source archive, there are the doctags.c program and a slightly modified
 vim2html.pl, which were taken from the original source archive of Vim 7.0 
 (although not an integral part of Vim but helper programs).

12.FAQs 							*faq*
 
 Q: We are in $Date: 2023-04-15 00:54:24 +0200 (Sat, 15 Apr 2023) $,
    so why do you still use the framebuffer, uh ?
 A: De gustibus non disputandum est.
    Well, actually I do not use it so often anymore.

 Q: Do you prefer complicated software over simple to use?
 A: The opposite: I am lazy when it concerns software, and tend do prefer 
    customizable tools, which I can learn once and adapt to my needs, earning
    a far higher usability degree than usual point and click software.
    Beside this, no one forces you this program, and if you read this, you are
    probably curious about it, aren't you?
    Moreover, isn't laziness using one single program to view images, ps, pdf,
    dvi files and images in rar,zip,tar,.. archives through a sole single 
    program ( |fimgs| )?
 
 Q: Is it true that no feature was removed from Fbi ?
 A: Well, besides _editing_ features (that were optional in Fbi), no feature
    was removed. Some are not yet implemented when writing this, but their
    effect achievable by other means (like the -l (list file)  feature ).

 Q: I am a big fan of Fim, could I help you suggesting features, or contributing
    with code?
 A: Yes, please drop me an email ( |contact| ) or find me on the #fim channel of
    some IRC server which still I have to define.

 Q: I wish to use Fim for commercial purposes, could I?
 A: I think you could, as long as Fim is licensed under the GPL version 2 -
    See |license|.

 Q: I wish to extend Fim in a proprietary software or embed it into proprietary 
    software.
 A: You couldn't, sorry. Type 'man gpl' to discover why. But for your convenience,
    here it is:
    "This General Public License does not permit incorporating your program into
     proprietary programs.  If your program is a subroutine library, you may consider
     it more useful to permit linking proprietary applications with the library.
     If this is what you want to do, use the GNU Library General Public License
     instead of this License."
    Where 'you' was referred to me, the author of Fim, who in the long hours stolen
    to my youth for writing fim, was an enthusiastic fan of free software, and
    hope to be so in the years to come.

 Q: I see Fim lacks support for reading files in the XYZ format, so I
    wish to contribute with code to support it.
 A: Then please use src/FbiStuffXyz.cpp as a model and |contact| me when done.

 Q: I wish to use Fim for military purposes, could I ?
 A: Remember me to add somewhere a clause to deny this to you.

 Q: I wish to donate you money, beer, pizza, or a new laptop; could I?
 A: Yes, you could. Just |contact| me for the details of sending me the goods.

 Q: I have problems with the framebuffer. Could you help me?
 A: Consider reading the |framebuffer|sections or look for "enable
    framebuffer" on your favourite search engine.

 Q: Which image file formats are supported ?
 A: Fim should display the more common file formats (png, jpeg, gif, bmp).
    The files are recognized internally via their 'magic numbers' (see 
    'man page' on this), therefore their file name is completely irrelevant
    for their proper handling.
    Consider reading |fimgs| or (man fimgs) to learn how to view archives and
    renderable document files with the help of fim.
    Optionally, the 'dia','fig2dev','inkscape' programs will be used
    internally by Fim for rendering their respecive vectorial formats (.dia,
    .fig,.svg) to a Fim interally supported format.
    Gimp's xcftopnm will be tried to read '.xcf' file format files.
    Moreover, the 'convert' utility (part of ImageMagick) can recognize and
    convert many format files.

 Q: Does Fim support animated gif images ?
 A: Currently no. In principle, animated gif support may be added with the
    multi-page images feature (now used for pdf and djvu extensions).

DESCRIPTION






fim is a
’swiss army knife’ for displaying image files.
It is capable of displaying image files using different
graphical devices while offering a uniform look and feel.
Key bindings are customizable and specified in an
initialization file. Interaction with standard input and
output is possible (especially in shell scripts). An
internal scripting language specialized for image viewing
allows image navigation, scaling, manipulation of internal
variables, command aliases, and vim-like autocommands. The
internal language can be interacted with via a command line
mode capable of autocompletion and history (the readline
mode). Further features are display of EXIF tags, JPEG
comments, EXIF rotation/orientation, load of
"description files", faster load via image
caching, command recording, and much more.



As a default,
fim displays the specified file(s) on the detected,
most convenient graphical device. This can be with SDL if
running under X, an Ascii Art driver (aalib or libcaca) if
running behind ssh without X forwarding, or the linux
framebuffer device. Graphical file formats BMP, PCX are
supported natively, while JPEG, PNG, GIF, TIFF, PPM, PGM,
PBM are supported via third party libraries. Further formats
are supported via external converters. For XCF
(Gimp’s) images, will try to use
’xcftopnm’. For FIG vectorial images, will try
to use ’fig2dev’. For DIA vectorial images, will
try to use ’dia’. For SVG vectorial images, will
try to use ’inkscape’. For other formats will
try to use ImageMagick’s ’convert’
executable. The converter is given 15 seconds for the
conversion before a timeout.



If
{imagepath} is a file, its format is guessed not by
its name but by its contents. See the _file_loader
variable to change this default.



If
{imagepath} is a directory, therein contained files
of supported formats will be loaded. If {imagepath}
contains a trailing slash (/), it will be treated as a
directory; otherwise this will be checked via
stat(2). To change this default, see description of
the _pushdir_re variable and the
--no-stat-push and --recursive options.



This man page
describes fim command line options and usage. See man
fimrc(5) for a full specification of the fim
language, commands, keysyms, autocommands, variables,
aliases, examples for a configuration file and readline
usage samples.



USAGE






You may invoke
fim from an interactive shell and control it with the
keyboard, as you would do with any image viewer with
reasonable key bindings.



fim is
keyboard oriented: there are no user menus or buttons
available. If you need some feature or setting which is not
accessible from the default keyboard configuration, you
probably need a custom configuration or simply need to type
a custom command. For these, you can use the internal
command and configuration language.



See options
--read-from-stdin, --script-from-stdin, and
--image-from-stdin for more script-oriented
usages.



The full
commands specification is also accessible at runtime using
the internal help system (typing :help).



OPTIONS






Accepted
command line {options}:











--






Treat arguments after -- as filenames. Treat
arguments before -- as command line options if these
begin with -, and as filenames otherwise.





-a,
--autozoom



Enable autozoom. fim
will automagically pick a reasonable zoom factor when
displaying a new image (as in fbi).



-b[24|1],
--binary[=24|1]



Display contents of binary
files (of any filetype) as these were raw 24 or 1 bits per
pixel pixelmaps. Image width will not exceed the value of
the _preferred_rendering_width variable. Regard this
as an easter bunny option.



--as-text



Display contents of files (of
any filetype) as these were text. Image width will not
exceed the value of the _preferred_rendering_width
variable. Non-printable characters will be displayed as
" ". Regard this as another easter bunny
option.



--cd-and-readdir



Step in the directory of the
first file to be loaded, push other files from that
directory, and jump back to the first file. Useful when
invoking from a desktop environment.



-c {commands},
--execute-commands {commands}



Execute commands after
reading the initialization file, just before entering the
interactive mode. No semicolon (;) is required at the
end of commands. Do not forget quoting
commands in a manner suitable to your shell. So -c
next is fine as it is. A more complicated example, with
quotings: -c ’*2;2pan_up;display;while(1){align
"bottom";sleep "1" ; align
"top"}’ (with the single quotes) tells fim
to: double the displayed image size, pan twice up, display
the image, and finally do an endless loop consisting of
bottom and top aligning, alternated.



-C {commands},
--execute-commands-early {commands}



Similar to the
--execute-commands option, but execute
commands earlier, just before reading the
initialization file. The special ’early’ form
=var=val will assign var to val
immediately, before the interpreter is started.



For example, -C
’_scale_style=" "’ starts fim
no auto-scaling; the equivalent early form is: -C
’=_scale_style= ’.



-d {framebuffer device},
--device {framebuffer device}



Framebuffer device to use.
Default is the one your vc is mapped to (as in fbi).




--dump-reference-help[=man]



Dump to stdout language
reference help and quit.




--dump-default-fimrc



Dump default configuration (the
one hardcoded in the fim executable) to standard output and
quit.



-E {scriptfile},
--execute-script {scriptfile}



Execute scriptfile after
the default initialization file is read, and before
executing --execute-commands commands.



-f {fimrc},
--etc-fimrc {fimrc}



Specify an alternative
system-wide initialization file (default:
/usr/local/etc/fimrc), to be read prior to any other
configuration file. See also --no-etc-fimrc-file.



-F {commands},
--final-commands {commands}



Similar to the
--execute-commands option, but execute
commands after exiting the interactive mode, just
before terminating the program.



-h[s|d|l|m],
--help[=s|d|l|m]



Print program invocation help,
and exit. Depending on the option, output can be: short,
descriptive, long from man, or complete man. If further
arguments follow, individual help messages will be shown
instead.



-k {keysym},
--keysym-press {keysym}



Execute any command bound (via
the bind command) to a specified keysym at startup. A keysym
can be prefixed by a repetition count number. You can
specify the option multiple times to simulate multiple
keystrokes. Presses entered via --keysym-press are
processed before presses entered via --chars-press.
See man fimrc(5) for a list of keysyms and the use of
bind.



-K {chars},
--chars-press {chars}



Input one or more keyboard
characters at program startup (simulate keyboard presses).
This option can be specified multiple times. Each additional
time (or if the string is empty), a press of Enter (ASCII
code 0x0D) key is prepended. Examples: -K ’’
simulates press of an Enter; -K ’:next;’
activates the command line and enter "next;"
without executing it; -K ":next;" -K
"next" executes "next", stays in the
command line and enter keys "next"; -K
":next;" -K "" -K "next"
executes "next", leaves the command line, and
executes in sequence any command bound to keys
’n’, ’e’, ’x’,
’t’. Presses entered via --chars-press
are processed after presses entered via
--keysym-press.



-D {filename},
--load-image-descriptions-file {filename}



Load image descriptions from
file filename. Each line begins with the basename of
an image file, followed by a Tab character (or a different
character if specified via
--image-descriptions-file-separator), then the
description text. The description text is copied into the
i:_comment variable of the image at load time,
overriding the comment possibly loaded from the file (e.g.
JPEG, PNG or TIFF comment). If a ’@’ followed by
and identifier {var} is encountered, and i:{var} is set, its
value is substituted here. If "@#" is encountered,
the remainder of the description line is ignored. Special
comment lines like "#!fim:var=val" lead i:var to
be assigned value val (unquoted) at image loading time
(cached variable); i:var will not be assigned if var starts
with an underscore (’_’). Special comment lines
like "#!fim:+=val" add val to current description.
Special comment lines like "#!fim:^=val" set val
to be the base of each description. Special comment lines
like "#!fim:!=" reset all cached variables.
Special comment lines like "#!fim:/=dir" prepend
dir to each file’s basename. Special comment lines
like "#!fim:\=dir" prepend dir to each
file’s name. Special description text (to be
associated to an image) begins with markers: with
"#!fim:=", the last description line is reused;
with "#!fim:+", what follows is appended to the
last description line; with "#!fim:^", what
follows is prepended to the last description line; with
"#!fim:s/f/t", the last description line will be
used after substitution of occurrences of substring f with
string t (f and t cannot contain newlines or a
’/’). If val is empty that variable is unset.
These variables are stored also in an internal index used by
the limit command. This option sets
_caption_over_image=2, so that a caption is displayed
over the image. A description file beginning with
"#!fim:desc" can be loaded without specifying this
switch.



-S {sepchar},
--image-descriptions-file-separator {sepchar}



A character to be used as a
separator between the filename and the description part of
lines specified just before a
--load-image-descriptions-file.



-i,
--image-from-stdin



Read one single image from the
standard input (the image data, not the filename). May not
work with all supported file formats. In the image list,
this image takes the special name
"<STDIN>".




--mark-from-image-descriptions-file
{filename}



Set those files specified in
filename (see --load-image-descriptions-file for the
file format) as marked (see the list command).



-m {vmode}, --mode
{vmode}



Name of the video mode to use
video mode (must be listed in /etc/fb.modes). Default is not
to change the video mode. In the past, the XF86 config file
(/etc/X11/XF86Config) used to contain Modeline information,
which could be fed to the modeline2fb perl script
(distributed with fbset). On many modern xorg based systems,
there is no direct way to obtain a fb.modes file from the
xorg.conf file. So instead one could obtain useful fb.modes
info by using the (fbmodes (no man page AFAIK)) tool,
written by bisqwit. An unsupported mode should make fim exit
with failure. But it is possible the kernel could trick fim
and set a supported mode automatically, thus ignoring the
user set mode.



-N,
--no-rc-file



No personal initialization file
will be read (default is ~/.fimrc) at startup.



--no-etc-fimrc-file



No system-wide initialization
file will be read (default is /usr/local/etc/fimrc) at
startup. See also --etc-fimrc.




--no-internal-config



No internal default
configuration at startup (uses internal variable
_no_default_configuration). Will only provide a
minimal working configuration.



--no-commandline



With internal command line mode
disabled.



--no-history-save



Do not save execution history
at finalization (uses internal variable
_save_fim_history).



--no-history-load



Do not load execution history
at startup.



--no-history



Do not load or save execution
history at startup.



-p,
--script-from-stdin



Read commands from stdin before
entering in interactive mode.



-o
[fb|sdl|ca|aa|imlib2|dumb], --output-device 

[fb|sdl|ca|aa|imlib2|dumb]



Will use the specified
device as fim video output device, overriding
automatic checks. The available devices depend on the
original configuration/compilation options, so you should
get the list of available output devices issuing fim
--version. The fb option selects the Linux
framebuffer. Presence of option S (e.g. fb=S)
makes framebuffer initialization more picky: it will not
tolerate running in a screen session. The ca option
(coloured Ascii Art) can be specified as
ca[={[’w’]}] ; if supplied,
’w’ selects windowed mode, provided
libcaca is running under X; by default (or with
’W’), windowed mode is being turned off
internally during initialization by unsetting the DISPLAY
environment variable. The aa (monochrome Ascii Art)
option can be specified as
aa[={[’w’|’W’]}]; if
supplied, ’w’ selects windowed mode,
provided aalib is running under X; by default (or with
’W’), windowed mode is being turned off
internally during initialization by unsetting the DISPLAY
environment variable. Please note that the readline
(internal command line) functionality in ca and
aa modes is limited. The sdl option (graphical
windowed mode) may be specified as sdl
={[’w’][’m’][’r’][’h’][’W’][’M’][’R’][’H’][width[:height]][’%’]},
where width and height are integer numbers
specifying the desired resolution (if height not
specified, it takes the value of width); the
’w’ character requests windowed mode
(instead of ’W’ for fullscreen); the
’m’ character requests mouse pointer
display; the ’h’ character requests help
grid map draw (can be repeated for variants); the
’r’ character requests support for window
resize; the ’%’ character requests to
treat width and height as percentage of
possible window resolution. The same letters uppercase
request explicit negation of the mentioned features. The
imlib2 option requests imlib2 and is unfinished -- do
not use it. The dumb test mode is not
interactive.



--offset
{bytes-offset[{:upper-offset}|{+offset-range}]}



Use the specified offset
(in bytes) for opening the specified files. If
:upper-offset is specified, further bytes until
upper-offset will be probed. If +offset-range
is specified instead, that many additional bytes will be
probed. Use this option to search damaged file systems for
image files. Appending a modifier among K,M,G (case
irrelevant) to an offset number changes the unit to be
respectively 2^10, 2^20, or 2^30 bytes.



--pread-cmd
{cmd-filter-pipeline}



Specify a shell command with
{cmd-filter-pipeline}. If the current filename
matches "^[/A-Za-z0-9_.][/A-Za-z0-9_.-]*$", it
will be substituted to any occurrence of ’{}’.
The resulting command output is assumed to be file data,
which will be read and displayed. This works by setting the
internal _pread_cmd variable (empty by default).



-P,
--text-reading



Enable textreading mode. This
has the effect that fim will display images scaled to the
width of the screen, and aligned to the top. If the images
you are watching are text pages, all you have to do to get
the next piece of text is to press space (in the default key
configuration, of course).



-s {value}, --scroll
{value}



Set scroll steps for internal
variable _steps (default is 20%).



--slideshow {number}



Interruptible slideshow mode.
Wait for {number} of seconds (assigned to the
_want_sleep_seconds variable) after each image.
Implemented by executing reload; i:fresh=1; while(_fileindex
<= _filelistlen-_loop_only_once){sleep
_want_sleep_seconds; next;} sleep _want_sleep_seconds; as a
first command. Can be interrupted by : or Esc. The other
keys will execute accordingly to their function but will not
interrupt the slideshow. Like in fbi, this will cycle
forever, unless --once is specified.



--sanity-check



Perform a quick sanity check,
just after the initialization, and terminate.



-t,
--no-framebuffer



fim Use an ASCII Art
driver. If present, use either of libcaca (coloured), or
aalib (monochrome). For more, see (man fimrc), (info aalib)
or (apropos caca)). If no ASCII Art driver was enabled at
compile time, fim will not display any image at all.



-T {terminal}, --vt
{terminal}



The terminal will be
used as virtual terminal device file (as in fbi). See (chvt
(1)), (openvt (1)) for more info about this. Use (con2fb
(1)) to map a terminal to a framebuffer device.



--reverse



Reverse files list before
browsing (can be combined with the other sorting
options).











--sort






Sort files list before browsing according to full
filename.
 





--sort-basename



Sort files list before browsing
according to file basename’s.



--sort-mtime



Sort files list before browsing
according to file modification time.



--sort-fsize



Sort files list before browsing
according to file size.



-u, --random



Randomly shuffle the files list
before browsing (seed depending on time() function).



--random-no-seed



Pseudo-random shuffle the files
list before browsing (no seeding).



-v, --verbose



Be verbose: show status
bar.



--verbose-load



Load files verbosely (repeat
option to increase verbosity).



--verbose-font-load



Load font verbosely (sets
_fbfont_verbosity).




--verbose-interpreter



Execute interpreter verbosely
(Sets immediately _debug_commands="ackC" if
specified once, _debug_commands="ackCi" if
specified twice).



-V, --version



Print to stdout program
version, compile flags, enabled features, linked libraries
information, supported filetypes/file loaders, and then
exit.



-w,
--autowidth



Scale the image according to
the screen width.



-=,
--no-auto-scale



Do not scale the images after
loading (will set ’_scale_style="
"’;).



--autowindow



Resize the window size (if
supported by the video mode) to the image size. Don’t
use this with other image scaling options.



--no-stat-push



Sets _push_checks=0
before initialization, thus disabling file/dir existence
checks with stat(2) at push push time (and speeding up
startup).



-H,
--autoheight



Scale the image according to
the screen height.



-W {scriptfile},
--write-scriptout {scriptfile}



All the characters that you
type are recorded in the file {scriptout}, until you
exit fim. This is useful if you want to create a
script file to be used with "fim -c" or
":exec" (analogous to Vim’s -s and
":source!"). If the {scriptout} file
exists, it will be not touched (as in Vim’s -w).



-L {fileslistfile},
--read-from-file {fileslistfile}



Read file list from a file:
each line one file to load (similar to
--read-from-stdin; use --read-from-stdin-elds
to control line breaking).



-, --read-from-stdin



Read file list from stdin: each
line one file to load; use with --read-from-stdin-elds to
control line breaking).



Note that these
the three standard input reading functionalities (-i,-p and
-) conflict : if two or more of them occur in fim
invocation, fim will exit with an error and warn about the
ambiguity.



See the section
INVOCATION EXAMPLES below to read some useful (and
unique) ways of employing fim.



--read-from-stdin-elds
{delimiter-char}



Specify an endline delimiter
character for breaking lines read via
-/--read-from-stdin/--read-from-file (which shall be
specified after this). Line text before the delimiter will
be treated as names of files to load; the text after will be
ignored. This is also useful e.g. to load description files
(see --load-image-descriptions-file) as filename list files.
Default is the newline character (0x0A); to specify an ASCII
NUL byte (0x00) use ’’.



-A, --autotop



Align images to the top border
(by setting ’_autotop=1’ after
initialization).



-q, --quiet



Quiet execution mode. Sets
_display_status=0;_display_busy=0;.



-r {width:height},
--resolution {width:height}



Set resolution specification in
pixels. Supported by SDL only. Will be appended to the
argument to --output-device. Shorthand value
’fullscreen’ will be translated into
’W’.



-R[{exp}],
--recursive[={exp}]



Push files/directories to the
files list recursively. The expression in variable
_pushdir_re (default:
".(JPG|PNG|GIF|BMP|TIFF|TIF|JPEG|JFIF|PPM|PGM|PBM|PCX|WEBP)$")
lists extensions of filenames which will be loaded in the
list. You can overwrite its value by optionally passing an
expression {exp} here as argument. If starting with
’+’ or ’|’, the expression following
will be appended to it.



-X,
--no-pipe-load



Do not load via external
converter programs: only use built-in file decoders.



-B,
--background-recursive



Push files/directories to the
files list recursively, in background during program
execution. Any sorting options will be ignored. Experimental
feature, unfinished.



--load-shadow-directory
{dir}



Add {dir} to the shadow
directory list. Then ’scale "shadow"’
will temporarily substitute the image being displayed with
that of the first same-named file located under a shadow
directory. Useful to browse low-res images, but still being
able to quickly view the hi-res original residing in a
shadow directory. This works as intended as long as unique
filenames are involved.



-/ {pattern}, --/
{pattern}



After startup jump to pattern;
short for -c ’/’.



--// {pattern}



After startup jump to pattern;
as -c ’/’ but with search on the full path (with
_re_search_opts="f").



-1, --once



If running --slideshow, loop
only once (as in fbi).



PROGRAM RETURN STATUS






The program
return status is 0 on correct operation; 252 on unsupported
device specification; 248 on bad input; 255 on a generic
error; 42 on a signal-triggered program exit; or a different
value in case of an another error. 

The return status may be controlled by the use of the quit
command.



COMMON KEYS AND COMMANDS






The following
keys and commands are hardcoded in the minimal
configuration. These are working by default before any
config loading, and before the hardcoded config loading (see
variable _fim_default_config_file_contents).



n goto
’+1f’ 

p goto ’-1f’ 

+ magnify 

- reduce 

h pan ’left’ 

l pan ’right’ 

k pan ’up-’ 

j pan ’down+’ 

q quit 

You can type a number before a command binding to iterate
the assigned command: 

3k 3pan ’up-’



: enter command
line mode 

:{number} jump to {number}^th image in the list












:^





jump to first image in the list









:$





jump to last image in the list





:*{factor} scale the image by
{factor} 

:{scale}% scale the image to the desired {scale} 

:+{scale}% scale the image up to the desired percentage
{scale} (relatively to the original) 

:-{scale}% scale the image down to the desired percentage
{scale} (relatively to the original)












/{regexp}








entering the pattern {regexp} (with /) makes fim jump to
the next image whose filename matches {regexp}












/*.png$








entering this pattern (with /) makes fim jump to the
next image whose filename ends with ’png’












/png







a shortcut for /.*png.*













2,4 stdout ’{}’








print three filenames to standard output.









!{syscmd}








executes the {syscmd} quoted string as an argument to
the "system" fim command.








You can
visualize all of the default bindings invoking fim
--dump-default-fimrc | grep bind . 

You can visualize all of the default aliases invoking fim
--dump-default-fimrc | grep alias .



The Return vs.
Space key thing can be used to create a file list while
reviewing the images and use the list for batch processing
later on.



All of the key
bindings are reconfigurable; see the default fimrc
file for examples on this, or read the complete manual: the
FIM.TXT file distributed with fim.



AFFECTING ENVIRONMENT VARIABLES














FBFONT









(just like in fbi) a Linux consolefont font file.





If using a gzipped font, the
zcat program will be used to uncompress it (via
execvp(3)). 

If not specified, the following files will be probed and the
first existing will be selected:




/usr/share/kbd/consolefonts/cp866-8x16.psf.gz


/usr/share/consolefonts/Uni3-TerminusBoldVGA14.psf.gz 

/usr/lib/kbd/consolefonts/lat9-16.psf.gz

/usr/share/consolefonts/default8x9.psf.gz 

/usr/share/consolefonts/Lat15-Fixed16.psf.gz 

/usr/share/consolefonts/default.psf.gz 

fim://



If the special
fim:// string is specified, a hardcoded font will be
used.











FBGAMMA









(just like in fbi) gamma correction (applies to dithered
8 bit mode only). Default is 1.0.








FRAMEBUFFER








(just like in fbi) user set framebuffer device file
(applies only to the fb mode).





If unset, fim will probe for
/dev/fb0.












TERM







(only in fim) will influence the output device selection
algorithm, especially if $TERM=="screen".









SSH_TTY






if set and no output device specified, give precedence
to ca, then aa (if present).









DISPLAY






If this variable is set, then the sdl driver will be
probed by default.





COMMON PROBLEMS






fim
needs read-write access to the framebuffer devices (/dev/fbN
or /dev/fb/N), i.e you (our your admin) have to make sure
fim can open the devices in rw mode. The IMHO most elegant
way is to use pam_console (see /etc/security/console.perms)
to chown the devices to the user logged in on the console.
Another way is to create some group, chown the special files
to that group and put the users which are allowed to use the
framebuffer device into the group. You can also make the
special files world writable, but be aware of the security
implications this has. On a private box it might be fine to
handle it this way through.



If using udev,
you can edit: /etc/udev/permissions.d/50-udev.permissions
and set these lines like here: 

# fb devices 

fb:root:root:0600 

fb[0-9]*:root:root:0600 

fb/*:root:root:0600



fim also
needs access to the linux console (i.e. /dev/ttyN) for sane
console switch handling. That is obviously no problem for
console logins, but any kind of a pseudo tty (xterm, ssh,
screen, ...) will not work.

NOTES






This manual
page is neither accurate nor complete. In particular, issues
related to driver selection shall be described more
accurately. Also the accurate sequence of autocommands
execution, variables application is critical to
understanding fim, and should be documented. The filename
"<STDIN>" is reserved for images read from
standard input (view this as a limitation), and thus
handling files with such name may incur in limitations. The
SDL driver is quite inefficient, for a variety of reasons.
In particular, its interaction with the readline library can
be problematic (e.g.: when running in sdl mode without a
terminal). This shall be fixed.



BUGS






fim has
bugs. Please read the BUGS file shipped in the
documentation directory to discover the known ones. There
are also inconsistencies in the way the internal command
line works across the different graphical devices.



FILES







/usr/local/share/doc/fim



The directory with fim
documentation files.




/usr/local/etc/fimrc



The system-wide fim
initialization file (executed at startup, after executing
the hardcoded configuration).











~/.fimrc






The personal fim initialization file (executed at
startup, after the system-wide initialization file).








~/.fim_history






File where to load from or save. See (man
fimrc(5), man readline(3)).








~/.inputrc






If fim is built with GNU readline support, it
will be susceptible to chages in the user set ~/.inputrc
configuration file contents. For details, see (man
readline(3)).

fimrc -
fim configuration file and language reference



SYNOPSIS






~/.fimrc


/usr/local/etc/fimrc 

fim --script-from-stdin [ {options} ] < {scriptfile} 

fim --execute-script {scriptfile} [ {options} ] 

fim --execute-commands {commands} [ {options} ] 

fim --final-commands {commands} [ {options} ] 

fim --write-scriptout {scriptfile} [ {options} ] 

fim --write-scriptout /dev/stdout [ {options} ] 

fim --chars-press :{commands} [ {options} ] 

fim --chars-press :{commands} --chars-press ’’ [
{options} ]



DESCRIPTION






This page
explains the fim language, which is used for the
fimrc configuration files, {scriptfile}s, or
{commands} passed via command line {options}. This language
can be used to issue commands (or programs) from the
internal program command line accessed interactively through
the ":" key (or rather, the key code specified by
the "_console_key" variable). One may exit
from command line mode by pressing the Enter key on an empty
line (a non empty command line would be submitted for
execution), or the Esc key (only in SDL mode). The general
form of a fim command/program is shown in the next
section.



FIM LANGUAGE GRAMMAR






This section
specifies the grammar of the fim language.



Language
elements surrounded by a single quote ("’")
are literals.



Warning: at the
present state, this grammar has conflicts. A future release
shall fix them.

A STRING can be
either a single quoted string or a double quoted string. A
floating point number can be either unquoted
(UNQUOTED_FLOAT) or quoted (QUOTED_FLOAT). A QUOTED_FLOAT is
a floating point number, either single ("’")
or double (""") quoted. An INTEGER shall be
an unsigned integer number. An IDENTIFIER shall be one of
the valid fim commands (see COMMANDS REFERENCE ) or a
valid alias. A VARIABLE shall be an already declared or
undeclared variable identifier (see VARIABLES
REFERENCE ) or a valid alias, created using the
alias command. The "=~" operator treats the
right expression as a STRING, and uses it as a regular
expression for matching purposes. The SLASH_AND_REGEXP is a
slash ("/") followed by a STRING, interpreted as a
regular expression. If ’INTEGER , INTEGER IDENTIFIER
arguments’ is encountered, command IDENTIFIER will be
repeated on each file in the interval between the two
INTEGERs, and substituting the given file name to any
’{}’ found in the commands arguments (which must
be quoted in order to be treated as strings). See
regex(1) for regular expression syntax.



The way some
one-line statements are evaluated:



: enter command
line mode 

:{number} jump to {number}^th image in the list












:^





jump to first image in the list









:$





jump to last image in the list





:*{factor} scale the image by
{factor} 

:{scale}% scale the image to the desired {scale} 

:+{scale}% scale the image up to the desired percentage
{scale} (relatively to the original) 

:-{scale}% scale the image down to the desired percentage
{scale} (relatively to the original)












/{regexp}








entering the pattern {regexp} (with /) makes fim jump to
the next image whose filename matches {regexp}












/*.png$








entering this pattern (with /) makes fim jump to the
next image whose filename ends with ’png’












/png







a shortcut for /.*png.*













2,4 stdout ’{}’








print three filenames to standard output.









!{syscmd}








executes the {syscmd} quoted string as an argument to
the "system" fim command.








COMMANDS REFERENCE






alias


alias [{identifier} [{commands} [{description}]]] 

Without arguments, lists the current aliases. 

With one, shows an identifier’s assigned command. 

With two, assigns to an identifier a user defined command or
sequence of commands. 

With three, also assigns a help string.



align


align
[’bottom’|’top’|’left’|right’]:
if image larger than drawing area, align one side of the
image to the border. 

align ’center’: align equally far from all
sides. 

align ’info’: print internal alignment
information.



autocmd


autocmd {event} {pattern} {commands}: manipulate
autocommands (inspired from Vim autocmd’s). 

Without arguments, list autocommands. 

With arguments, specifies for which type of event and which
current file open, which commands to execute. 

See the default built-in configuration files for
examples.




autocmd_del


autocmd_del: specify autocommands to delete. 

Usage: autocmd_del {event} {pattern} {commands}.




basename


basename {filename}: returns the basename of {filename} in
the ’_last_cmd_output’ variable.



bind


bind [{keysym} [{commands}]]: bind a keyboard
symbol/shortcut {keysym} to {commands}. 

If {keysym} is at least two characters long and begins with
0 (zero), the integer number after the 0 will be treated as
a raw keycode to bind the specified {keysym} to. 

Use the ’_verbose_keys’ variable to discover
(display device dependent) raw keys. 

Key binding is dynamical, so you can rebind keys even during
program’s execution. 

You can get a list of valid symbols (keysyms) by invoking
dump_key_codes or in the man page.



cd 

cd {path}: change the current directory to {path}. 

If {path} is a file, use its base directory name. 

cd ’-’ will change to the previous current
directory (before the last ’:cd {path}’
command).



clear


clear: clear the virtual console.




commands


commands: display the existing commands.



color


color [desaturate]: desaturate the displayed image colors.


color [negate]: negate the displayed image colors. 

color [colorblind|c|deuteranopia|d]: simulate a form of the
deuteranopia color vision deficiency (cvd). 

color [protanopia|p]: simulate a form of the protanopia cvd.


color [tritanopia|t]: simulate a form of the tritanopia cvd.


color [daltonize|D]: if following a cvd specification, will
attempt correcting it. 

color [identity]: populate the image with ’RGB
identity’ pixels. 

To get back the original you will have to reload the
image.



crop


crop: crop image to a centered rectangle, half the width and
half the height. 

crop {p}: crop image to the middle {p} horizontal percent
and {p} vertical percent of the image. 

crop {w} {h}: crop image to the middle {w} horizontal
percent and {h} vertical percent of the image. 

crop {x1} {y1} {x2} {y2}: crop image to the area between the
upper left ({x1},{y1}) and lower right ({x2},{y2}) corner.


Units are intended as percentage (0 to 100). 

Note: still experimental functionality.



desc


desc ’load’ {filename} [{sepchar}]: load
description file {filename}, using the optional {sepchar}
character as separator. 

desc ’reload’: load once again description files
specified at the command line with
--load-image-descriptions-file, with respective separators.


desc [’-all’] [’-append’]
[’-nooverw’] ’save’ {filename}
[{sepchar}]: save current list descriptions to file
{filename}, using the optional {sepchar} character as
separator, and if ’-all’ is present will save
the variables, and if ’-append’ is present, will
only append, and if ’-nooverw’ is present, will
not overwrite existing files. 

See documentation of --load-image-descriptions-file for the
format of {filename}.



display


display [’reinit’ {string}]|’resize’
{w} {h}]: display the current file contents. 

If ’reinit’ switch is supplied, the
’{string}’ specifier will be used to
reinitialize (e.g.: change resolution, window system
options) the display device. 

See documentation for the --output-device command line
switch for allowed values of {string}. 

If ’resize’ and no argument, will ask the window
manager to size the window like the image. 

If ’resize’ and two arguments, these will be
used as width and height of window, to set.




dump_key_codes


dump_key_codes: dump the active key codes (unescaped, for
inspection purposes).



echo


echo {args}: print the {args} on console.



else


if(expression){action;}[’else’{action;}]: see
else.



eval


eval {args}: evaluate {args} as commands, executing
them.



exec


exec {filename(s)}: execute script {filename(s)}.



font


font ’scan’ [{dirname}]: scan {dirname} or
/usr/share/consolefonts looking for fonts in the internal
fonts list. 

font ’load’ {filename}: load font {filename}.


font ’next’/’prev’: load
next/previous font in the internal fonts list. 

font ’info’: print current font filename.



getenv


getenv {identifier}: create a variable with the same value
as the ’{identifier}’ environment variable, but
with an identifier prefixed by ’ENV_’. So e.g.
getenv ’DISPLAY’ creates
’ENV_DISPLAY’. Nothing is being printed; no
variable is created if {identifier} is empty.



goto


goto
{[’+’|’-’]{number}[’%’][’f’|’p’|’F’|’P’]}
| {/{regexp}/} | {?{filename}} | {’+//’} |
{’+/’|’-/’}[C] |
{{’+’|’-’}{identifier}[’+’]}:
jump to an image. 

If {number} is given, and not surrounded by any specifier,
will go to image at index {number}. 

If followed by ’%’, the effective index will be
computed as a percentage to the current available images.


If prepended by ’-’ or ’+’, the jump
will be relative to the current index. 

The ’f’ specifier asks for the jump to occur
within the files (same for ’F’, but accelerates
if keep pressing). 

The ’p’ specifier asks for the jump to occur in
terms of pages, within the current file (same for
’P’, but accelerates if keep pressing). 

If /{regexp}/ is given, will jump to the first image
matching the given /{regexp}/ regular expression pattern.


If the argument starts with ?, jump to the filename
following ?. 

If given ’+//’, will jump to the first different
image matching the last given regular expression pattern.


With ’+/’C or ’-/’C will jump to
next or previous file according to C: if ’s’ if
same directory, if ’d’ if down the directory
hierarchy, if ’u’ if down the directory
hierarchy, if ’b’ if same basename, if upper
case match is negative, if missing defaults to
’S’ (jump to file in different dir). 

If {identifier|identifier2...}] is encountered after a
’+’ or ’-’ sign, jump to next or
previous image having a different value for any
corresponding i:{identifier} (a trailing ’+’
will require a non empty value). 

Match will occur on both file name and description, possibly
loaded via desc or --load-image-descriptions-file; see also
’_lastgotodirection’ and
’_re_search_opts’. 

You can specify multiple arguments to goto: those after the
first triggering a jump will be ignored. 

Executes autocommands for events PreGoto and PostGoto.
Keeping pressed shall accelerate images browsing.



help


help [{identifier}]: provide online help, assuming
{identifier} is a variable, alias, or command identifier.


If {identifier} begins with ’/’, the search will
be on the help contents and a list of matching items will be
given instead. 

A list of commands can be obtained simply invoking
’commands’; a list of aliases with
’alias’; a list of bindings with
’bind’.



if 

if(expression){action;}[’else’{action;}]: see
’else’.



info


info: display information about the current file.



limit


limit {’-list’|’-listall’}
’variable’|[’-further’|’-merge’|’-subtract’]
[{expression} |{variable} {value}]: A browsable file list
filtering function (like limiting in the ’mutt’
program). Uses information loaded via
--load-image-descriptions-file. 

If invoked with ’-list’/’-listall’
only, will list the current description variable ids. 

If invoked with ’-list’/’-listall’
’id’, will list set values for the variable
’id’. 

If ’-further’ is present, will start with the
current list; if not, with the full list. 

If ’-merge’ is present, new matches will be
merged in the existing list and sorted. 

If ’-subtract’ is present, sort and filter out
matches. 

If {variable} and {values} are provided, limit to files
having property {variable} set to {value}. 

If {expression} is one exclamation point (’!’),
will limit to the currently marked files only. 

If {expression} is ’~!’ will limit to files with
unique basename. 

if ’~=’, to files with duplicate basename. 

if ’~^’, to the first of the files with
duplicate basename. 

if ’~$’, to the last of the files with duplicate
basename. 

On ’~i’ [MINIDX][-][MAXIDX], (each a number
possibly followed by a multiplier ’K’) will
limit on filenames in position MINIDX to MAXIDX. 

On ’~z’ will limit to files having the current
file’s size. 

on ’~z’ [MINSIZE][-][MAXSIZE], (each a number
possibly followed by a multiplier among
’k’,’K’,’m’,’M’)
will limit on filesize within these limits. 

on ’~d’ will limit to files having the current
file’s date +- one day. 

on ’~d’ [MINTIME][-][MAXTIME], (each the count
of seconds since the Epoch (First of Jan. of 1970) or a date
as DD/MM/YYYY) will limit on file time (struct stat’s
’st_mtime’, in seconds) within this interval.


For other values of {expression}, limit to files whose
description string matches {expression}. 

Invoked with no arguments, the original browsable files list
is restored.



list


list: display the files list. 

list ’random_shuffle’: randomly shuffle the file
list. 

list ’reverse’: reverse the file list. 

list ’clear’: clear the file list. 

list ’sort’: sort the file list. 

list ’sort_basename’: sort the file list
according to base name. 

list ’sort_comment’: sort the file list
according to the value of the _comment variable. 

list ’sort_var’ {var}: sort the file list
according to the value of the i:{var} variable. 

list ’vars|variables’: list variables in all i:*
read from description file. 

list ’sort_fsize’: sort the file list according
to file size. 

list ’sort_mtime’: sort the file list according
to modification date. 

list ’pop’: remove the current file from the
files list, and step back. 

list ’remove’ [{filename(s)}]: remove the
current file, or the {filename(s)}, if specified. 

list ’push’ {filename(s)}: push {filename(s)} to
the back of the files list. 

list ’filesnum’: display the number of files in
the files list. 

list ’mark’ [{args}]: mark image file names for
stdout printing at exit, with {args} mark the ones matching
according to the rules of the ’limit’ command,
otherwise the current file. 

list ’unmark’ [{args}]: unmark marked image file
names, with {args} unmark the ones matching according to the
rules of the ’limit’ command, otherwise the
current file. 

list ’marked’: show which files have been marked
so far. 

list ’dumpmarked’: dump to stdout the marked
files (you will want usually to ’unmarkall’
afterwards). 

list ’markall’: mark all the current list files.


list ’unmarkall’: unmark all the marked files.


list ’pushdir’ {dirname}: will push all the
files in {dirname}, when matching the regular expression in
variable _pushdir_re or, if empty, from constant regular
expression
’.(JPG|PNG|GIF|BMP|TIFF|TIF|JPEG|JFIF|PPM|PGM|PBM|PCX|WEBP)$’.


list ’pushdirr’ {dirname}: like pushdir, but
will also push encountered directory entries recursively.


list ’swap’: will move the current image
filename to the first in the list (you’ll have to
invoke reload to see the effect). 

Of the above commands, several will be temporarily non
available for the duration of a background load (enabled by
--background-recursive), which will last until
_loading_in_background is 0.



load

The namespaces
in which variables may exist are: current image, global. A
namespace is specified by a prefix, which can be:

limits) is ok provided _max_cached_memory is set
meaningfully. 

_max_cached_memory [in,g:] the maximum amount of memory
(in KiB) at which images will be continued being added to
the cache. Setting this to 0 (no limit) will lead to a crash

_orientation [internal,i:] Orthogonal clockwise rotation
(orientation) is controlled by:
’i:_orientation’, ’g:_orientation’
and applied on a per-image basis. In particular, the values
of the three variables are summed up and the sum is
interpreted as the image orientation. If the sum is 0, no
rotation will apply; if it is 1, a single ( 90’)
rotation will apply; if it is 2, a double (180’)
rotation will apply; if it is 3, a triple (270’)
rotation will apply. If the sum is not one of 0,1,2,3, the
value of the sum modulo 4 is considered. Therefore,
":i:_orientation=1" and
":i:_orientation=5" are equivalent: they rotate
the image one time by 90’. 

_pread_cmd [in,g:] a user-specified shell command
emitting an image on stdout, in a format readable by the
convert utility. If the current filename matches
"^[/A-Za-z0-9_.][/A-Za-z0-9_.-]*$", it will be

bit based rendering will use this value for a default
document width (instead of a default value). 

_push_checks [in,experimental,g:] if 1 (default), will
check with stat() existence of input files before
push’ing them (set this to 0 to speed up loading very
long file lists; in these cases a trailing slash (/) will
have to be used to tell fim a pathname is a directory). This
only works after initialization (thus, after command line
files have been push’ed); use --no-stat-push if you
wish to set this to 0 at command line files specification.


_push_pushes_dirs [in,g:] if 1, the push command will
also accept and push directories (using pushdir). if 2, will
also push hidden files/directories, that is, ones whose
names begin with a dot (.). 

_pushdir_re [in] regular expression to match against
when pushing files from a directory or an archive. By
default this is
".(JPG|PNG|GIF|BMP|TIFF|TIF|JPEG|JFIF|PPM|PGM|PBM|PCX|WEBP)$".


_pwd [out,g:] the current working directory; will be
updated at startup and whenever the working directory
changes. 

_re_search_opts [in,g:] affects regexp-based searches;
if an empty string, defaults will apply; if contains
’i’ (’I’), case insensitive
(sensitive) searches will occur; if contains
’b’, will match on basename, if contains
’f’ on full pathname. 

_reduce_factor [in,g:] the image scale multiplier used
when reducing images size. 

_retry_loader_probe [in,g:] if 1 and user specified a
file loader and this fails, will probe for a different
loader. 

_rows [in,g:] if >0, will set the number of displayed
text lines in the console.

fed to the scale command; see its documentation for possible
values. 

_screen_height [out] the screen height. 

_screen_width [out,g:] the screen width. 

_scroll_skip_page_fraction [int,g:] if >1, fraction
of page which will be skipped in when scrolling (e.g.
’scrollforward’); if 1, auto chosen; if <1,
disabled. 

_seek_magic [optional,g:] will seek a
’magic’ signature in the file after opening it,
and will try decoding it starting within the range of that
signature (use like this: fim -C
’_seek_magic=MAGIC_STRING;push filename’).


_status_line [in,g:] if 1, will display the status bar.


_steps [in,g:] the default steps, in pixels, when
panning images. 

_sys_rc_file [in,g:] string with the global
configuration file name. 

_use_exiftool [in,g:] if >0 and supported, exiftool
will be used to get additional information. if 1, this will
be appened to _comment; if 2, will go to _exiftool_comment.


_use_mipmaps [in,g:] if >0, will use mipmaps to speed
up downscaling of images (this has a memory overhead
equivalent to one image copy); mipmaps will not be cached.
If 2, will use every fourth source pixel instead of
averaging (good for photos, not for graphs). 

_verbose_errors [in,g:] if 1, will display on stdout
internal errors, while parsing commands. 

_verbose_keys [in,g:] if 1, after each interactive mode
key hit, the console will display the hit key raw keycode.

supported by the display device (currently only SDL). if set
to a number that is not 0, will show the status (or command)
line in the window manager caption; if set to a non-empty

(see _info_fmt_str); if empty, will show the program
version. 

_want_wm_mouse_ctrl [in,g:] if at least 9 chars long,
enable mouse click/movement behaviour when in SDL mode; the

unalias command. 

Further default aliases are usually loaded at startup -- see
the CONFIGURATION FILE EXAMPLE section below.



COMMAND LINE USAGE EXAMPLES






# jump to the
third image: 

3; 

# jump to first image: 

^; 

# jump to last image: 

$; 

# magnify the image two times: 

*2; 

# scale the image to the 30% of the original: 

30%; 

# scale the image up by 30%: 

+30%; 

# scale the image down by 30%: 

-30%; 

# jump to the next image whose filename matches the
".*jpg" regular expression: 

/.*jpg; 

# executes the "date" system command 

!"date";



CONFIGURATION FILE EXAMPLE






Part of the
default configuration comes from the
_fim_default_config_file_contents variable, shown
here. 

One can skip its loading by using the
_no_default_configuration variable.

# Note that usually a ~/.fimrc file is read after these
options take effect, so you could reset all of this with
ease. 

# Lines beginning with a pound (#) are ignored by fim (they

# It is wise the input variables are set at the beginning of

.SH NAME
fimgs - poor man's [http://]PostScript/pdf/dvi/cbr/rar/cbz/zip viewer based on fim
.SH SYNOPSIS
.B fimgs [ {fimgs-options} ] file [-- [{fim-options}]]
.SH DESCRIPTION
.B fimgs  
is a wrapper script which takes a PostScript or pdf or .cbr or .rar or .cbz or .zip or .dvi or any of the above prefixed with http:// or https:// or ssh: as input, renders the pages using ghostscript into a temporary directory and finally calls \fB fim\fP to display them.

In case of compressed archives (in ZIP or RAR formats), the images are decompressed into a directory and displayed using \fB fim\fP.
In this case, only images contained in the archive will be displayed (no nested archives or pdf's or ps's or dvi's).

The temporary directory name will be of the form $TMPDIR/fbps-$$.
If the $TMPDIR environment variable is unset, /dev/shm and /var/tmp will be checked for existence and permissions. 
The $$ above is the script process ID.
The script deletes the temporary directory when \fB fim\fP terminates.

NAME






fimgs - poor
man’s [http://]PostScript/pdf/dvi/cbr/rar/cbz/zip
viewer based on fim



SYNOPSIS






fimgs [
{fimgs-options} ] file [-- [{fim-options}]]



DESCRIPTION






fimgs is
a wrapper script which takes a PostScript or pdf or .cbr or
.rar or .cbz or .zip or .dvi or any of the above prefixed
with http:// or https:// or ssh: as input, renders the pages
using ghostscript into a temporary directory and finally
calls fim to display them.



In case of
compressed archives (in ZIP or RAR formats), the images are
decompressed into a directory and displayed using
fim. In this case, only images contained in the
archive will be displayed (no nested archives or pdf’s
or ps’s or dvi’s).



The temporary
directory name will be of the form $TMPDIR/fbps-$$. If the
$TMPDIR environment variable is unset, /dev/shm and /var/tmp
will be checked for existence and permissions. The $$ above
is the script process ID. The script deletes the temporary
directory when fim terminates.



In order to
uncompress RAR archives, fimgs will use
’unrar-nonfree’ or ’rar’ or
’unrar-free’.



In order to
uncompress ZIP archives, fimgs will use
’zip’.



In order to
uncompress BZ2 files, ’bunzip2’ will be used, if
present.



In order to
uncompress TAR.GZ or TAR.BZ2 or TAR.XZ archives, fimgs will
use ’tar’.



In order to
fetch http:// or https:// prefixed URLS, ’wget’
will be used, if present.



In order to
fetch ssh: prefixed host:path locations, ’scp’
will be used.



In case of a
CBZ, CBR, PDF, PS, or DVI file, will invoke fim with
’--autotop --autowidth’.



OPTIONS






To pass through
options to fim, you may specify them after
"--".



Default options
are ’--autozoom’.



-r
{resolution} Specify resolution for the ’gs’
-r option (e.g.: 96x96; default 120x120).











-m






Dump a man page for fimgs.








-p
{password}



Specify password for the
’gs’ -p (password) option.











-h






Will display a help message.

.SH DESCRIPTION
This page explains the 
.B fim
language, which is used for the 
.B fimrc
configuration files, {scriptfile}s, or {commands} passed via command line {options}.
This language can be used to issue commands (or programs) from the internal program command line accessed interactively through the ":" key (or rather, the key code specified by the "\fB_console_key\fP" variable).
One may exit from command line mode by pressing the Enter key on an empty line (a non empty command line would be submitted for execution), or the Esc key  (only in SDL mode).
The general form of a fim command/program is shown in the next section.


.SH FIM LANGUAGE GRAMMAR
This section specifies the grammar of the 
.B fim
language.

Language elements surrounded by a single quote ("'") are literals.

Warning: at the present state, this grammar has conflicts. A future release shall fix them.

            | QUOTED_FLOAT
            | UNQUOTED_FLOAT
            | STRING

A STRING can be either a single quoted string or a double quoted string.
A floating point number can be either unquoted (UNQUOTED_FLOAT) or quoted (QUOTED_FLOAT).
A QUOTED_FLOAT is a floating point number, either single ("'") or double (""") quoted.
An INTEGER shall be an unsigned integer number.
An IDENTIFIER shall be one of the valid fim commands (see 
.B COMMANDS REFERENCE
) or a valid alias.
A VARIABLE shall be an already declared or undeclared variable identifier (see 
.B VARIABLES REFERENCE
) or a valid alias, created using the 
.B alias
command.
The "=~" operator treats the right expression as a STRING, and uses it as a regular expression for matching purposes.
The SLASH_AND_REGEXP is a slash ("/") followed by a STRING, interpreted as a regular expression.
If 'INTEGER , INTEGER IDENTIFIER arguments' is encountered, command IDENTIFIER will be repeated on each file in the interval between the two INTEGERs, and substituting the given file name to any '{}' found in the commands arguments (which must be quoted in order to be treated as strings).
See \fR\fIregex\fR(1) for regular expression syntax.

The way some one\-line statements are evaluated:

.nf
:       enter command line mode
:{number}       jump to {number}^th image in the list
:^	        jump to first image in the list
:$	        jump to last image in the list
:*{factor}      scale the image by {factor}
:{scale}%       scale the image to the desired {scale}
:+{scale}%       scale the image up to the desired percentage {scale} (relatively to the original)
:\-{scale}%       scale the image down to the desired percentage {scale} (relatively to the original)

/{regexp}		 entering the pattern {regexp} (with /) makes fim jump to the next image whose filename matches {regexp}
/*.png$		 entering this pattern (with /) makes fim jump to the next image whose filename ends with 'png'
/png		 a shortcut for /.*png.*

2,4 stdout '{}'	print three filenames to standard output.


!{syscmd}		executes the {syscmd} quoted string as an argument to the  "system" fim command.

.fi
If {number} is given, and not surrounded by any specifier, will go to image at index {number}.
.fi
If followed by '%', the effective index will be computed as a percentage to the current available images.

.SH COMMAND LINE USAGE EXAMPLES
.nf
# jump to the third image:
3;
# jump to first image:
^;
# jump to last image:
$;
# magnify the image two times:
*2;
# scale the image to the 30% of the original:
30%;
# scale the image up by 30%:
+30%;
# scale the image down by 30%:
\-30%;
# jump to the next image whose filename matches the ".*jpg" regular expression:
/.*jpg;
# executes the "date" system command
!"date";

.SH CONFIGURATION FILE EXAMPLE
Part of the default configuration comes from the \fB_fim_default_config_file_contents\fP variable, shown here.
.nf
One can skip its loading by using the \fB_no_default_configuration\fP variable.

.SH DESCRIPTION
.B
fim
is a `swiss army knife' for displaying image files.
It is capable of displaying image files using different graphical devices while offering a uniform look and feel.
Key bindings are customizable and specified in an initialization file.
Interaction with standard input and output is possible (especially in shell scripts).
An internal scripting language specialized for image viewing allows image navigation, scaling, manipulation of internal variables, command aliases, and vim-like autocommands.
The internal language can be interacted with via a command line mode capable of autocompletion and history (the readline mode).
Further features are display of EXIF tags, JPEG comments, EXIF rotation/orientation, load of "description files", faster load via image caching, command recording, and much more.

As a default,
.B
fim
displays the specified file(s) on the detected, most convenient graphical device. This can be with SDL if running under X, an Ascii Art driver (aalib or libcaca) if running behind ssh without X forwarding, or the linux framebuffer device. Graphical file formats BMP, PCX are supported natively, while JPEG, PNG, GIF, TIFF, PPM, PGM, PBM are supported via third party libraries. 
Further formats are supported via external converters. 
For XCF (Gimp's) images, will try to use 'xcftopnm'.
For FIG vectorial images, will try to use 'fig2dev'.
For DIA vectorial images, will try to use 'dia'.
For SVG vectorial images, will try to use 'inkscape'.
For other formats will try to use ImageMagick's 'convert' executable.
The converter is given 15 seconds for the conversion before a timeout.


If \fB{imagepath}\fP is a file, its format is guessed not by its name but by its contents. See the \fB_file_loader\fP variable to change this default.


If \fB{imagepath}\fP is a directory, therein contained files of supported formats will be loaded. If \fB{imagepath}\fP contains a trailing slash (/), it will be treated as a directory; otherwise this will be checked via \fBstat(2)\fP. To change this default, see description of the \fB_pushdir_re\fP variable and the \fB--no-stat-push\fP and \fB--recursive\fP options.

This man page describes 
.B fim
command line options and usage.
See man \fR\fIfimrc\fR(5) for a full specification of the 
.B
fim
language, commands, keysyms, autocommands, variables, aliases, examples for a configuration file and readline usage samples.

.SH USAGE
You may invoke
.B
fim
from an interactive shell and control it with the keyboard, as you would do with any image viewer with reasonable key bindings.

.B
fim
is keyboard oriented: there are no user menus or buttons available.
If you need some feature or setting which is not accessible from the default keyboard configuration, you probably need a custom configuration or simply need to type a custom command. For these, you can use the internal command and configuration language.

See options \fB--read-from-stdin\fP, \fB--script-from-stdin\fP, and \fB--image-from-stdin\fP for more script-oriented usages.

The full commands specification is also accessible at runtime using the internal help system (typing :help).


.SH OPTIONS
Accepted command line \fB{options}\fP:
.TP
\fB--\fP
Treat arguments after \fB--\fP
as filenames.
Treat arguments before \fB--\fP
as command line options if these begin with
\fB-\fP, 
and as filenames otherwise.

.TP
\fB-a\fP, \fB--autozoom\fP
Enable autozoom. \fBfim\fP will automagically pick a reasonable zoom factor when displaying a new image (as in \fBfbi\fP).
.TP
\fB-b[24|1]\fP, \fB--binary[=24|1]\fP
Display contents of binary files (of any filetype) as these were raw 24 or 1 bits per pixel pixelmaps.
Image width will not exceed the value of the \fB_preferred_rendering_width\fP variable.
Regard this as an easter bunny option.

.TP
\fB--as-text\fP
Display contents of files (of any filetype) as these were text.
Image width will not exceed the value of the \fB_preferred_rendering_width\fP variable.
Non-printable characters will be displayed as " ".
Regard this as another easter bunny option.

.TP
\fB--cd-and-readdir\fP
Step in the directory of the first file to be loaded, push other files from that directory, and jump back to the first file.
Useful when invoking from a desktop environment.
.TP
\fB-c {commands}\fP, \fB--execute-commands {commands}\fP
Execute \fBcommands\fP after reading the initialization file, just before entering the interactive mode.
No semicolon (\fB;\fP) is required at the end of \fBcommands\fP.
Do not forget quoting \fBcommands\fP in a manner suitable to your shell.
So  -c next  is fine as it is.
A more complicated example, with quotings:
-c '*2;2pan_up;display;while(1){align "bottom";sleep "1" ; align "top"}'
(with the single quotes) tells fim to: double the displayed image 
size, pan twice up, display the image, and finally 
do an endless loop consisting of bottom and top aligning, alternated.

.TP
\fB-C {commands}\fP, \fB--execute-commands-early {commands}\fP
Similar to the \fB--execute-commands\fP option, but execute \fBcommands\fP earlier, just before reading the initialization file.
The special 'early' form \fB=var=val\fP will assign \fBvar\fP to \fBval\fP immediately, before the interpreter is started.

For example,
-C '\fB_scale_style\fP=" "' starts fim no auto-scaling;
the equivalent early form is:
-C '=\fB_scale_style\fP= '.


.TP
\fB-d {framebuffer device}\fP, \fB--device {framebuffer device}\fP
Framebuffer device to use. Default is the one your vc is mapped to (as in fbi).
.TP
\fB--dump-reference-help[=man]\fP
Dump to stdout language reference help and quit.
.TP
\fB--dump-default-fimrc\fP
Dump default configuration (the one hardcoded in the fim executable) to standard output and quit.
.TP
\fB-E {scriptfile}\fP, \fB--execute-script {scriptfile}\fP
Execute \fBscriptfile\fP after the default initialization file is read, and before executing \fB--execute-commands\fP commands.
.TP
\fB-f {fimrc}\fP, \fB--etc-fimrc {fimrc}\fP
Specify an alternative system-wide initialization file (default: @sysconfdir@/fimrc), to be read prior to any other configuration file. See also \fB--no-etc-fimrc-file\fP. 

.TP
\fB-F {commands}\fP, \fB--final-commands {commands}\fP
Similar to the \fB--execute-commands\fP option, but execute \fBcommands\fP after exiting the interactive mode, just before terminating the program.
.TP
\fB-h[s|d|l|m]\fP, \fB--help[=s|d|l|m]\fP
Print program invocation help, and exit. Depending on the option, output can be: short, descriptive, long from man, or complete man. If further arguments follow, individual help messages will be shown instead.
.TP
\fB-k {keysym}\fP, \fB--keysym-press {keysym}\fP
Execute any command bound (via the bind command) to a specified keysym at startup. A keysym can be prefixed by a repetition count number. You can specify the option multiple times to simulate multiple keystrokes. Presses entered via \fB--keysym-press\fP are processed before presses entered via \fB--chars-press\fP. See man \fR\fIfimrc\fR(5) for a list of keysyms and the use of bind.
.TP
\fB-K {chars}\fP, \fB--chars-press {chars}\fP
Input one or more keyboard characters at program startup (simulate keyboard presses). This option can be specified multiple times. Each additional time (or if the string is empty), a press of Enter (ASCII code 0x0D) key is prepended. Examples: -K '' simulates press of an Enter;  -K ':next;' activates the command line and enter "next;" without executing it;  -K ":next;" -K "next" executes "next", stays in the command line and enter keys "next";  -K ":next;" -K "" -K "next" executes "next", leaves the command line, and executes in sequence any command bound to keys 'n', 'e', 'x', 't'. Presses entered via \fB--chars-press\fP are processed after presses entered via \fB--keysym-press\fP. 
.TP
\fB-D {filename}\fP, \fB--load-image-descriptions-file {filename}\fP
Load image descriptions from file \fBfilename\fP. Each line begins with the basename of an image file, followed by a Tab character (or a different character if specified via \fB--image-descriptions-file-separator\fP), then the description text. The description text is copied into the \fBi:_comment\fP variable of the image at load time, overriding the comment possibly loaded from the file (e.g. JPEG, PNG or TIFF comment). If a '@' followed by and identifier {var} is encountered, and i:{var} is set, its value is substituted here. If "@#" is encountered, the remainder of the description line is ignored. Special comment lines like "#!fim:var=val" lead i:var to be assigned value val (unquoted) at image loading time (cached variable); i:var will not be assigned if var starts with an underscore ('_'). Special comment lines like "#!fim:+=val" add val to current description. Special comment lines like "#!fim:^=val" set val to be the base of each description. Special comment lines like "#!fim:!=" reset all cached variables. Special comment lines like "#!fim:/=dir" prepend dir to each file's basename. Special comment lines like "#!fim:\e=dir" prepend dir to each file's name. Special description text (to be associated to an image) begins with markers:  with "#!fim:=", the last description line is reused; with "#!fim:+", what follows is appended to the last description line; with "#!fim:^", what follows is prepended to the last description line; with "#!fim:s/f/t", the last description line will be used after substitution of occurrences of substring f with string t (f and t cannot contain newlines or a '/'). If val is empty that variable is unset. These variables are stored also in an internal index used by the limit command. This option sets \fB_caption_over_image\fP=2, so that a caption is displayed over the image. A description file beginning with "#!fim:desc" can be loaded without specifying this switch.
.TP
\fB-S {sepchar}\fP, \fB--image-descriptions-file-separator {sepchar}\fP
A character to be used as a separator between the filename and the description part of lines specified just before a --load-image-descriptions-file.
.TP
\fB-i\fP, \fB--image-from-stdin\fP
Read one single image from the standard input (the image data, not the filename).  May not work with all supported file formats.
In the image list, this image takes the special name "".

.TP
\fB--mark-from-image-descriptions-file {filename}\fP
Set those files specified in \fBfilename\fP (see --load-image-descriptions-file for the file format) as marked (see the list command).

.TP
\fB-m {vmode}\fP, \fB--mode {vmode}\fP
Name of the video mode to use video mode (must be listed in /etc/fb.modes).  Default is not to change the video mode.  In the past, the XF86 config file (/etc/X11/XF86Config) used to contain Modeline information, which could be fed to the modeline2fb perl script (distributed with fbset).  On many modern xorg based systems, there is no direct way to obtain a fb.modes file from the xorg.conf file.  So instead one could obtain useful fb.modes info by using the (fbmodes (no man page AFAIK)) tool, written by bisqwit.  An unsupported mode should make fim exit with failure.  But it is possible the kernel could trick fim and set a supported mode automatically, thus ignoring the user set mode.
.TP
\fB-N\fP, \fB--no-rc-file\fP
No personal initialization file will be read (default is ~/.fimrc) at startup.
.TP
\fB--no-etc-fimrc-file\fP
No system-wide initialization file will be read (default is @sysconfdir@/fimrc) at startup. See also \fB--etc-fimrc\fP. 

.TP
\fB--no-internal-config\fP
No internal default configuration at startup (uses internal variable \fB_no_default_configuration\fP). Will only provide a minimal working configuration. 
.TP
\fB--no-commandline\fP
With internal command line mode disabled.
.TP
\fB--no-history-save\fP
Do not save execution history at finalization (uses internal variable \fB_save_fim_history\fP). 
.TP
\fB--no-history-load\fP
Do not load execution history at startup. 
.TP
\fB--no-history\fP
Do not load or save execution history at startup. 
.TP
\fB-p\fP, \fB--script-from-stdin\fP
Read commands from stdin before entering in interactive mode.
.TP
\fB-o [fb|sdl|ca|aa|imlib2|dumb]\fP, \fB--output-device [fb|sdl|ca|aa|imlib2|dumb]\fP
Will use the specified \fBdevice\fP as fim video output device, overriding automatic checks.
The available devices depend on the original configuration/compilation options, so you should
get the list of available output devices issuing \fBfim --version\fP.
The \fBfb\fP option selects the Linux framebuffer. Presence of option \fBS\fP (e.g. \fBfb=S\fP) makes framebuffer initialization more picky: it will not tolerate running in a screen session.
The \fBca\fP option (coloured Ascii Art) can be specified as \fBca\fP\fB[={['w']}] \fP; if supplied, \fB'w'\fP selects windowed mode, provided libcaca is running under X; by default (or with \fB'W'\fP), windowed mode is being turned off internally during initialization by unsetting the DISPLAY environment variable.
The \fBaa\fP (monochrome Ascii Art) option can be specified as \fBaa[={['w'|'W']}]\fP; if supplied, \fB'w'\fP selects windowed mode, provided aalib is running under X; by default (or with \fB'W'\fP), windowed mode is being turned off internally during initialization by unsetting the DISPLAY environment variable.
Please note that the readline (internal command line) functionality in \fBca\fP and \fBaa\fP modes is limited.
The \fBsdl\fP option (graphical windowed mode) may be specified as  \fBsdl\:={['w']['m']['r']['h']['W']['M']['R']['H'][width[:height]]['%']}\fP, where \fBwidth\fP and \fBheight\fP are integer numbers specifying the desired resolution  (if \fBheight\fP not specified, it takes the value of \fBwidth\fP); the \fB'w'\fP character requests windowed mode (instead of \fB'W'\fP for fullscreen); the \fB'm'\fP character requests mouse pointer display; the \fB'h'\fP character requests help grid map draw (can be repeated for variants); the \fB'r'\fP character requests support for window resize; the \fB'%'\fP character requests to treat \fBwidth\fP and \fBheight\fP as percentage of possible window resolution. The same letters uppercase request explicit negation of the mentioned features.
The \fBimlib2\fP option requests imlib2 and is unfinished -- do not use it.
The \fBdumb\fP test mode is not interactive.

.TP
\fB--offset {bytes-offset[{:upper-offset}|{+offset-range}]}\fP
Use the specified \fBoffset\fP (in bytes) for opening the specified files. If \fB:upper-offset\fP is specified, further bytes until \fBupper-offset\fP will be probed. If \fB+offset-range\fP is specified instead, that many additional bytes will be probed.  Use this option to search damaged file systems for image files. Appending a modifier among K,M,G (case irrelevant) to an offset number changes the unit to be respectively 2^10, 2^20, or 2^30 bytes.
.TP
\fB--pread-cmd {cmd-filter-pipeline}\fP
Specify a shell command with \fB{cmd-filter-pipeline}\fP. If the current filename matches "^[/A-Za-z0-9_.][/A-Za-z0-9_.-]*$", it will be substituted to any occurrence of '{}'. The resulting command output is assumed to be file data, which will be read and displayed.
This works by setting the internal \fB_pread_cmd\fP variable (empty by default).
.TP
\fB-P\fP, \fB--text-reading\fP
Enable textreading mode.  This has the effect that fim will display images scaled to the width of the screen, and aligned to the top.  If the images you are watching are text pages, all you have to do to get the next piece of text is to press space (in the default key configuration, of course).
.TP
\fB-s {value}\fP, \fB--scroll {value}\fP
Set scroll steps for internal variable \fB_steps\fP (default is 20%).
.TP
\fB--slideshow {number}\fP
Interruptible slideshow mode. Wait for \fB{number}\fP of seconds (assigned to the \fB_want_sleep_seconds\fP variable) after each image. Implemented by executing reload; i:fresh=1; while(_fileindex <= _filelistlen-_loop_only_once){sleep _want_sleep_seconds; next;} sleep _want_sleep_seconds;  as a first command. Can be interrupted by : or Esc. The other keys will execute accordingly to their function but will not interrupt the slideshow. Like in fbi, this will cycle forever, unless \fB--once\fP is specified.
.TP
\fB--sanity-check\fP
Perform a quick sanity check, just after the initialization, and terminate.
.TP
\fB-t\fP, \fB--no-framebuffer\fP
\fBfim\fP Use an ASCII Art driver. If present, use either of libcaca (coloured), or aalib (monochrome). For more, see (man fimrc), (info aalib) or (apropos caca)).
If no ASCII Art driver was enabled at compile time, fim will not display any image at all.
.TP
\fB-T {terminal}\fP, \fB--vt {terminal}\fP
The \fBterminal\fP will be used as virtual terminal device file (as in fbi).
See (chvt (1)), (openvt (1)) for more info about this.
Use (con2fb (1)) to map a terminal to a framebuffer device.

.TP
\fB--reverse\fP
Reverse files list before browsing (can be combined with the other sorting options).
.TP
\fB--sort\fP
Sort files list before browsing according to full filename.
.TP
\fB--sort-basename\fP
Sort files list before browsing according to file basename's.
.TP
\fB--sort-mtime\fP
Sort files list before browsing according to file modification time.
.TP
\fB--sort-fsize\fP
Sort files list before browsing according to file size.
.TP
\fB-u\fP, \fB--random\fP
Randomly shuffle the files list before browsing (seed depending on time() function).
.TP
\fB--random-no-seed\fP
Pseudo-random shuffle the files list before browsing (no seeding).
.TP
\fB-v\fP, \fB--verbose\fP
Be verbose: show status bar.
.TP
\fB--verbose-load\fP
Load files verbosely (repeat option to increase verbosity).
.TP
\fB--verbose-font-load\fP
Load font verbosely (sets \fB_fbfont_verbosity\fP).
.TP
\fB--verbose-interpreter\fP
Execute interpreter verbosely (Sets immediately \fB_debug_commands\fP="ackC" if specified once, \fB_debug_commands\fP="ackCi" if specified  twice).
.TP
\fB-V\fP, \fB--version\fP
Print to stdout program version, compile flags, enabled features, linked libraries information, supported filetypes/file loaders, and then exit.
.TP
\fB-w\fP, \fB--autowidth\fP
Scale the image according to the screen width.
.TP
\fB-=\fP, \fB--no-auto-scale\fP
Do not scale the images after loading (will set '\fB_scale_style\fP=" "';).
.TP
\fB--autowindow\fP
Resize the window size (if supported by the video mode) to the image size. Don't use this with other image scaling options.
.TP
\fB--no-stat-push\fP
Sets \fB_push_checks\fP=0 before initialization, thus disabling file/dir existence checks with stat(2) at push push time (and speeding up startup).
.TP
\fB-H\fP, \fB--autoheight\fP
Scale the image according to the screen height.
.TP
\fB-W {scriptfile}\fP, \fB--write-scriptout {scriptfile}\fP
All the characters that you type are recorded in the file \fB{scriptout}\fP, until you exit \fBfim\fP.  This is useful if you want to create a script file to be used with "fim -c" or ":exec" (analogous to Vim's -s and ":source!").  If the \fB{scriptout}\fP file exists, it will be not touched (as in Vim's -w). 
.TP
\fB-L {fileslistfile}\fP, \fB--read-from-file {fileslistfile}\fP
Read file list from a file: each line one file to load (similar to \fB--read-from-stdin\fP; use \fB--read-from-stdin-elds\fP to control line breaking).


.TP
\fB -, \fP\fB--read-from-stdin\fP
Read file list from stdin: each line one file to load; use with --read-from-stdin-elds to control line breaking).

Note that these the three standard input reading functionalities (-i,-p and -) conflict : if two or more of them occur in fim invocation, fim will exit with an error and warn about the ambiguity.

See the section
.B INVOCATION EXAMPLES
below to read some useful (and unique) ways of employing fim.

.TP
\fB--read-from-stdin-elds {delimiter-char}\fP
Specify an endline delimiter character for breaking lines read via -/--read-from-stdin/--read-from-file (which shall be specified after this). Line text before the delimiter will be treated as names of files to load; the text after will be ignored. This is also useful e.g. to load description files (see --load-image-descriptions-file) as filename list files. Default is the newline character (0x0A); to specify an ASCII NUL byte (0x00) use ''.

.TP
\fB-A\fP, \fB--autotop\fP
Align images to the top border (by setting '\fB_autotop\fP=1' after initialization).
.TP
\fB-q\fP, \fB--quiet\fP
Quiet execution mode. Sets _display_status=0;_display_busy=0;.

.TP
\fB-r {width:height}\fP, \fB--resolution {width:height}\fP
Set resolution specification in pixels. Supported by SDL only. Will be appended to the argument to --output-device. Shorthand value 'fullscreen' will be translated into 'W'. 
.TP
\fB-R[{exp}]\fP, \fB--recursive[={exp}]\fP
Push files/directories to the files list recursively. The expression in variable \fB_pushdir_re\fP (default: "\.(JPG|PNG|GIF|BMP|TIFF|TIF|JPEG|JFIF|PPM|PGM|PBM|PCX|WEBP)$") lists extensions of filenames which will be loaded in the list. You can overwrite its value by optionally passing an expression \fB{exp}\fP here as argument. If starting with '+' or '|', the expression following will be appended to it. 
.TP
\fB-X\fP, \fB--no-pipe-load\fP
Do not load via external converter programs: only use built-in file decoders.
.TP
\fB-B\fP, \fB--background-recursive\fP
Push files/directories to the files list recursively, in background during program execution. Any sorting options will be ignored. Experimental feature, unfinished.
.TP
\fB--load-shadow-directory {dir}\fP
Add \fB{dir}\fP to the shadow directory list. Then 'scale "shadow"' will temporarily substitute the image being displayed with that of the first same-named file located under a shadow directory. Useful to browse low-res images, but still being able to quickly view the hi-res original residing in a shadow directory. This works as intended as long as unique filenames are involved.
.TP
\fB-/ {pattern}\fP, \fB--/ {pattern}\fP
After startup jump to pattern; short for -c '/'.
.TP
\fB--// {pattern}\fP
After startup jump to pattern; as -c '/' but with search on the full path (with \fB_re_search_opts="f"\fP).
.TP
\fB-1\fP, \fB--once\fP
If running --slideshow, loop only once (as in fbi).

.SH PROGRAM RETURN STATUS
The program return status is 0 on correct operation; 252 on unsupported device specification; 248 on bad input; 255 on a generic error; 42 on a signal-triggered program exit;  or a different value in case of an another error.
 The return status may be controlled by the use of the quit command.
.SH COMMON KEYS AND COMMANDS
.nf
The following keys and commands are hardcoded in the minimal configuration. These are working by default before any config loading, and before the hardcoded config loading (see variable \fB_fim_default_config_file_contents\fP).

 n    goto '+1f'
 p    goto '-1f'
 +    magnify
 -    reduce
 h    pan 'left'
 l    pan 'right'
 k    pan 'up-'
 j    pan 'down+'
 q    quit
You can type a number before a command binding to iterate the assigned command:
3k    3pan 'up-'

.nf
:       enter command line mode
:{number}       jump to {number}^th image in the list
:^	        jump to first image in the list
:$	        jump to last image in the list
:*{factor}      scale the image by {factor}
:{scale}%       scale the image to the desired {scale}
:+{scale}%       scale the image up to the desired percentage {scale} (relatively to the original)
:-{scale}%       scale the image down to the desired percentage {scale} (relatively to the original)

/{regexp}		 entering the pattern {regexp} (with /) makes fim jump to the next image whose filename matches {regexp}
/*.png$		 entering this pattern (with /) makes fim jump to the next image whose filename ends with 'png'
/png		 a shortcut for /.*png.*

2,4 stdout '{}'	print three filenames to standard output.


!{syscmd}		executes the {syscmd} quoted string as an argument to the  "system" fim command.


You can visualize all of the default bindings invoking fim --dump-default-fimrc | grep bind .
You can visualize all of the default aliases invoking fim  --dump-default-fimrc | grep alias .

.fi
.P
The Return vs. Space key thing can be used to create a file list while
reviewing the images and use the list for batch processing later on.

All of the key bindings are reconfigurable; see the default 
.B fimrc
file for examples on this, or read the complete manual: the FIM.TXT file
distributed with fim.
.SH AFFECTING ENVIRONMENT VARIABLES

fim://

If the special fim:// string is specified, a hardcoded font will be used.
FBGAMMA		(just like in fbi) gamma correction (applies to dithered 8 bit mode only). Default is 1.0.
FRAMEBUFFER	(just like in fbi) user set framebuffer device file (applies only to the fb mode).
If unset, fim will probe for /dev/fb0.
TERM		(only in fim) will influence the output device selection algorithm, especially if $TERM=="screen".
SSH_TTY	if set and no output device specified, give precedence to ca, then aa (if present).
DISPLAY	If this variable is set, then the sdl driver will be probed by default.
.SH COMMON PROBLEMS
.B fim
needs read-write access to the framebuffer devices (/dev/fbN or /dev/fb/N), i.e you (our
your admin) have to make sure fim can open the devices in rw mode.
The IMHO most elegant way is to use pam_console (see
/etc/security/console.perms) to chown the devices to the user logged
in on the console.  Another way is to create some group, chown the
special files to that group and put the users which are allowed to use
the framebuffer device into the group.  You can also make the special
files world writable, but be aware of the security implications this
has.  On a private box it might be fine to handle it this way
through.

If using udev, you can edit:
/etc/udev/permissions.d/50-udev.permissions
and set these lines like here:
 # fb devices
 fb:root:root:0600
 fb[0-9]*:root:root:0600
 fb/*:root:root:0600
.P

.B fim
also needs access to the linux console (i.e. /dev/ttyN) for sane
console switch handling.  That is obviously no problem for console
logins, but any kind of a pseudo tty (xterm, ssh, screen, ...) will
.B not
work.

.SH NOTES
This manual page is neither accurate nor complete. In particular, issues related to driver selection shall be described more accurately. Also the accurate sequence of autocommands execution, variables application is critical to understanding fim, and should be documented.
The filename "" is reserved for images read from standard input (view this as a limitation), and thus handling files with such name may incur in limitations.
The SDL driver is quite inefficient, for a variety of reasons. In particular, its interaction with the readline library can be problematic (e.g.: when running in sdl mode without a terminal). This shall be fixed.
.SH BUGS
\fBfim\fP has bugs. Please read the 
.B BUGS
file shipped in the documentation directory to discover the known ones.
There are also inconsistencies in the way the internal command line works across the different graphical devices.

.TP
\fB\-\-mark\-from\-image\-descriptions\-file {filename}\fP
Set those files specified in \fBfilename\fP (see \-\-load\-image\-descriptions\-file for the file format) as marked (see the list command).

.TP
\fB\-m {vmode}\fP, \fB\-\-mode {vmode}\fP
Name of the video mode to use video mode (must be listed in /etc/fb.modes).  Default is not to change the video mode.  In the past, the XF86 config file (/etc/X11/XF86Config) used to contain Modeline information, which could be fed to the modeline2fb perl script (distributed with fbset).  On many modern xorg based systems, there is no direct way to obtain a fb.modes file from the xorg.conf file.  So instead one could obtain useful fb.modes info by using the (fbmodes (no man page AFAIK)) tool, written by bisqwit.  An unsupported mode should make fim exit with failure.  But it is possible the kernel could trick fim and set a supported mode automatically, thus ignoring the user set mode.
.TP
\fB\-N\fP, \fB\-\-no\-rc\-file\fP
No personal initialization file will be read (default is ~/.fimrc) at startup.
.TP
\fB\-\-no\-etc\-fimrc\-file\fP
No system\-wide initialization file will be read (default is /usr/local/etc/fimrc) at startup. See also \fB\-\-etc\-fimrc\fP. 

.TP
\fB\-\-no\-internal\-config\fP
No internal default configuration at startup (uses internal variable \fB_no_default_configuration\fP). Will only provide a minimal working configuration. 
.TP
\fB\-\-no\-commandline\fP
With internal command line mode disabled.
.TP
\fB\-\-no\-history\-save\fP
Do not save execution history at finalization (uses internal variable \fB_save_fim_history\fP). 
.TP
\fB\-\-no\-history\-load\fP
Do not load execution history at startup. 
.TP
\fB\-\-no\-history\fP
Do not load or save execution history at startup. 
.TP
\fB\-p\fP, \fB\-\-script\-from\-stdin\fP
Read commands from stdin before entering in interactive mode.
.TP
\fB\-o [fb|sdl|ca|aa|imlib2|dumb]\fP, \fB\-\-output\-device [fb|sdl|ca|aa|imlib2|dumb]\fP
Will use the specified \fBdevice\fP as fim video output device, overriding automatic checks.
The available devices depend on the original configuration/compilation options, so you should
get the list of available output devices issuing \fBfim \-\-version\fP.
The \fBfb\fP option selects the Linux framebuffer. Presence of option \fBS\fP (e.g. \fBfb=S\fP) makes framebuffer initialization more picky: it will not tolerate running in a screen session.
The \fBca\fP option (coloured Ascii Art) can be specified as \fBca\fP\fB[={['w']}] \fP; if supplied, \fB'w'\fP selects windowed mode, provided libcaca is running under X; by default (or with \fB'W'\fP), windowed mode is being turned off internally during initialization by unsetting the DISPLAY environment variable.
The \fBaa\fP (monochrome Ascii Art) option can be specified as \fBaa[={['w'|'W']}]\fP; if supplied, \fB'w'\fP selects windowed mode, provided aalib is running under X; by default (or with \fB'W'\fP), windowed mode is being turned off internally during initialization by unsetting the DISPLAY environment variable.
Please note that the readline (internal command line) functionality in \fBca\fP and \fBaa\fP modes is limited.
The \fBsdl\fP option (graphical windowed mode) may be specified as  \fBsdl\:={['w']['m']['r']['h']['W']['M']['R']['H'][width[:height]]['%']}\fP, where \fBwidth\fP and \fBheight\fP are integer numbers specifying the desired resolution  (if \fBheight\fP not specified, it takes the value of \fBwidth\fP); the \fB'w'\fP character requests windowed mode (instead of \fB'W'\fP for fullscreen); the \fB'm'\fP character requests mouse pointer display; the \fB'h'\fP character requests help grid map draw (can be repeated for variants); the \fB'r'\fP character requests support for window resize; the \fB'%'\fP character requests to treat \fBwidth\fP and \fBheight\fP as percentage of possible window resolution. The same letters uppercase request explicit negation of the mentioned features.
The \fBimlib2\fP option requests imlib2 and is unfinished \-\- do not use it.
The \fBdumb\fP test mode is not interactive.

.TP
\fB\-\-offset {bytes\-offset[{:upper\-offset}|{+offset\-range}]}\fP
Use the specified \fBoffset\fP (in bytes) for opening the specified files. If \fB:upper\-offset\fP is specified, further bytes until \fBupper\-offset\fP will be probed. If \fB+offset\-range\fP is specified instead, that many additional bytes will be probed.  Use this option to search damaged file systems for image files. Appending a modifier among K,M,G (case irrelevant) to an offset number changes the unit to be respectively 2^10, 2^20, or 2^30 bytes.
.TP
\fB\-\-pread\-cmd {cmd\-filter\-pipeline}\fP
Specify a shell command with \fB{cmd\-filter\-pipeline}\fP. If the current filename matches "^[/A\-Za\-z0\-9_.][/A\-Za\-z0\-9_.\-]*$", it will be substituted to any occurrence of '{}'. The resulting command output is assumed to be file data, which will be read and displayed.
This works by setting the internal \fB_pread_cmd\fP variable (empty by default).
.TP
\fB\-P\fP, \fB\-\-text\-reading\fP
Enable textreading mode.  This has the effect that fim will display images scaled to the width of the screen, and aligned to the top.  If the images you are watching are text pages, all you have to do to get the next piece of text is to press space (in the default key configuration, of course).
.TP
\fB\-s {value}\fP, \fB\-\-scroll {value}\fP
Set scroll steps for internal variable \fB_steps\fP (default is 20%).
.TP
\fB\-\-slideshow {number}\fP
Interruptible slideshow mode. Wait for \fB{number}\fP of seconds (assigned to the \fB_want_sleep_seconds\fP variable) after each image. Implemented by executing reload; i:fresh=1; while(_fileindex <= _filelistlen\-_loop_only_once){sleep _want_sleep_seconds; next;} sleep _want_sleep_seconds;  as a first command. Can be interrupted by : or Esc. The other keys will execute accordingly to their function but will not interrupt the slideshow. Like in fbi, this will cycle forever, unless \fB\-\-once\fP is specified.
.TP
\fB\-\-sanity\-check\fP
Perform a quick sanity check, just after the initialization, and terminate.
.TP
\fB\-t\fP, \fB\-\-no\-framebuffer\fP
\fBfim\fP Use an ASCII Art driver. If present, use either of libcaca (coloured), or aalib (monochrome). For more, see (man fimrc), (info aalib) or (apropos caca)).
If no ASCII Art driver was enabled at compile time, fim will not display any image at all.
.TP
\fB\-T {terminal}\fP, \fB\-\-vt {terminal}\fP
The \fBterminal\fP will be used as virtual terminal device file (as in fbi).
See (chvt (1)), (openvt (1)) for more info about this.
Use (con2fb (1)) to map a terminal to a framebuffer device.

.TP
\fB\-\-reverse\fP
Reverse files list before browsing (can be combined with the other sorting options).
.TP
\fB\-\-sort\fP
Sort files list before browsing according to full filename.
.TP
\fB\-\-sort\-basename\fP
Sort files list before browsing according to file basename's.
.TP
\fB\-\-sort\-mtime\fP
Sort files list before browsing according to file modification time.
.TP
\fB\-\-sort\-fsize\fP
Sort files list before browsing according to file size.
.TP
\fB\-u\fP, \fB\-\-random\fP
Randomly shuffle the files list before browsing (seed depending on time() function).
.TP
\fB\-\-random\-no\-seed\fP
Pseudo\-random shuffle the files list before browsing (no seeding).
.TP
\fB\-v\fP, \fB\-\-verbose\fP
Be verbose: show status bar.
.TP
\fB\-\-verbose\-load\fP
Load files verbosely (repeat option to increase verbosity).
.TP
\fB\-\-verbose\-font\-load\fP
Load font verbosely (sets \fB_fbfont_verbosity\fP).
.TP
\fB\-\-verbose\-interpreter\fP
Execute interpreter verbosely (Sets immediately \fB_debug_commands\fP="ackC" if specified once, \fB_debug_commands\fP="ackCi" if specified  twice).
.TP
\fB\-V\fP, \fB\-\-version\fP
Print to stdout program version, compile flags, enabled features, linked libraries information, supported filetypes/file loaders, and then exit.
.TP
\fB\-w\fP, \fB\-\-autowidth\fP
Scale the image according to the screen width.
.TP
\fB\-=\fP, \fB\-\-no\-auto\-scale\fP
Do not scale the images after loading (will set '\fB_scale_style\fP=" "';).
.TP
\fB\-\-autowindow\fP
Resize the window size (if supported by the video mode) to the image size. Don't use this with other image scaling options.
.TP
\fB\-\-no\-stat\-push\fP
Sets \fB_push_checks\fP=0 before initialization, thus disabling file/dir existence checks with stat(2) at push push time (and speeding up startup).
.TP
\fB\-H\fP, \fB\-\-autoheight\fP
Scale the image according to the screen height.
.TP
\fB\-W {scriptfile}\fP, \fB\-\-write\-scriptout {scriptfile}\fP
All the characters that you type are recorded in the file \fB{scriptout}\fP, until you exit \fBfim\fP.  This is useful if you want to create a script file to be used with "fim \-c" or ":exec" (analogous to Vim's \-s and ":source!").  If the \fB{scriptout}\fP file exists, it will be not touched (as in Vim's \-w). 
.TP
\fB\-L {fileslistfile}\fP, \fB\-\-read\-from\-file {fileslistfile}\fP
Read file list from a file: each line one file to load (similar to \fB\-\-read\-from\-stdin\fP; use \fB\-\-read\-from\-stdin\-elds\fP to control line breaking).


.TP
\fB \-, \fP\fB\-\-read\-from\-stdin\fP
Read file list from stdin: each line one file to load; use with \-\-read\-from\-stdin\-elds to control line breaking).

Note that these the three standard input reading functionalities (\-i,\-p and \-) conflict : if two or more of them occur in fim invocation, fim will exit with an error and warn about the ambiguity.

See the section
.B INVOCATION EXAMPLES
below to read some useful (and unique) ways of employing fim.

.TP
\fB\-\-read\-from\-stdin\-elds {delimiter\-char}\fP
Specify an endline delimiter character for breaking lines read via \-/\-\-read\-from\-stdin/\-\-read\-from\-file (which shall be specified after this). Line text before the delimiter will be treated as names of files to load; the text after will be ignored. This is also useful e.g. to load description files (see \-\-load\-image\-descriptions\-file) as filename list files. Default is the newline character (0x0A); to specify an ASCII NUL byte (0x00) use ''.

.TP
\fB\-A\fP, \fB\-\-autotop\fP
Align images to the top border (by setting '\fB_autotop\fP=1' after initialization).
.TP
\fB\-q\fP, \fB\-\-quiet\fP
Quiet execution mode. Sets _display_status=0;_display_busy=0;.

.TP
\fB\-r {width:height}\fP, \fB\-\-resolution {width:height}\fP
Set resolution specification in pixels. Supported by SDL only. Will be appended to the argument to \-\-output\-device. Shorthand value 'fullscreen' will be translated into 'W'. 
.TP
\fB\-R[{exp}]\fP, \fB\-\-recursive[={exp}]\fP
Push files/directories to the files list recursively. The expression in variable \fB_pushdir_re\fP (default: "\.(JPG|PNG|GIF|BMP|TIFF|TIF|JPEG|JFIF|PPM|PGM|PBM|PCX|WEBP)$") lists extensions of filenames which will be loaded in the list. You can overwrite its value by optionally passing an expression \fB{exp}\fP here as argument. If starting with '+' or '|', the expression following will be appended to it. 
.TP
\fB\-X\fP, \fB\-\-no\-pipe\-load\fP
Do not load via external converter programs: only use built\-in file decoders.
.TP
\fB\-B\fP, \fB\-\-background\-recursive\fP
Push files/directories to the files list recursively, in background during program execution. Any sorting options will be ignored. Experimental feature, unfinished.
.TP
\fB\-\-load\-shadow\-directory {dir}\fP
Add \fB{dir}\fP to the shadow directory list. Then 'scale "shadow"' will temporarily substitute the image being displayed with that of the first same\-named file located under a shadow directory. Useful to browse low\-res images, but still being able to quickly view the hi\-res original residing in a shadow directory. This works as intended as long as unique filenames are involved.
.TP
\fB\-/ {pattern}\fP, \fB\-\-/ {pattern}\fP
After startup jump to pattern; short for \-c '/'.
.TP
\fB\-\-// {pattern}\fP
After startup jump to pattern; as \-c '/' but with search on the full path (with \fB_re_search_opts="f"\fP).
.TP
\fB\-1\fP, \fB\-\-once\fP
If running \-\-slideshow, loop only once (as in fbi).

.SH PROGRAM RETURN STATUS
The program return status is 0 on correct operation; 252 on unsupported device specification; 248 on bad input; 255 on a generic error; 42 on a signal\-triggered program exit;  or a different value in case of an another error.
 The return status may be controlled by the use of the quit command.
.SH COMMON KEYS AND COMMANDS
.nf
The following keys and commands are hardcoded in the minimal configuration. These are working by default before any config loading, and before the hardcoded config loading (see variable \fB_fim_default_config_file_contents\fP).

 n    goto '+1f'
 p    goto '\-1f'
 +    magnify
 \-    reduce
 h    pan 'left'
 l    pan 'right'
 k    pan 'up\-'
 j    pan 'down+'
 q    quit
You can type a number before a command binding to iterate the assigned command:
3k    3pan 'up\-'

.nf
:       enter command line mode
:{number}       jump to {number}^th image in the list
:^	        jump to first image in the list
:$	        jump to last image in the list
:*{factor}      scale the image by {factor}
:{scale}%       scale the image to the desired {scale}
:+{scale}%       scale the image up to the desired percentage {scale} (relatively to the original)
:\-{scale}%       scale the image down to the desired percentage {scale} (relatively to the original)

/{regexp}		 entering the pattern {regexp} (with /) makes fim jump to the next image whose filename matches {regexp}
/*.png$		 entering this pattern (with /) makes fim jump to the next image whose filename ends with 'png'
/png		 a shortcut for /.*png.*

2,4 stdout '{}'	print three filenames to standard output.


!{syscmd}		executes the {syscmd} quoted string as an argument to the  "system" fim command.


You can visualize all of the default bindings invoking fim \-\-dump\-default\-fimrc | grep bind .
You can visualize all of the default aliases invoking fim  \-\-dump\-default\-fimrc | grep alias .

.fi
.P
The Return vs. Space key thing can be used to create a file list while
reviewing the images and use the list for batch processing later on.

All of the key bindings are reconfigurable; see the default 
.B fimrc
file for examples on this, or read the complete manual: the FIM.TXT file
distributed with fim.
.SH AFFECTING ENVIRONMENT VARIABLES
.nf
FBFONT		(just like in fbi) a Linux consolefont font file.
If using a gzipped font, the zcat program will be used to uncompress it (via \fBexecvp(3)\fP).
If not specified, the following files will be probed and the first existing will be selected:

/usr/share/kbd/consolefonts/cp866\-8x16.psf.gz
/usr/share/consolefonts/Uni3\-TerminusBoldVGA14.psf.gz

/usr/share/consolefonts/Lat15\-Fixed16.psf.gz
/usr/share/consolefonts/default.psf.gz
fim://

If the special fim:// string is specified, a hardcoded font will be used.
FBGAMMA		(just like in fbi) gamma correction (applies to dithered 8 bit mode only). Default is 1.0.
FRAMEBUFFER	(just like in fbi) user set framebuffer device file (applies only to the fb mode).
If unset, fim will probe for /dev/fb0.
TERM		(only in fim) will influence the output device selection algorithm, especially if $TERM=="screen".
SSH_TTY	if set and no output device specified, give precedence to ca, then aa (if present).
DISPLAY	If this variable is set, then the sdl driver will be probed by default.
.SH COMMON PROBLEMS
.B fim
needs read\-write access to the framebuffer devices (/dev/fbN or /dev/fb/N), i.e you (our
your admin) have to make sure fim can open the devices in rw mode.
The IMHO most elegant way is to use pam_console (see
/etc/security/console.perms) to chown the devices to the user logged
in on the console.  Another way is to create some group, chown the
special files to that group and put the users which are allowed to use
the framebuffer device into the group.  You can also make the special
files world writable, but be aware of the security implications this
has.  On a private box it might be fine to handle it this way
through.

If using udev, you can edit:
/etc/udev/permissions.d/50\-udev.permissions
and set these lines like here:
 # fb devices
 fb:root:root:0600
 fb[0\-9]*:root:root:0600
 fb/*:root:root:0600
.P

.B fim
also needs access to the linux console (i.e. /dev/ttyN) for sane
console switch handling.  That is obviously no problem for console
logins, but any kind of a pseudo tty (xterm, ssh, screen, ...) will
.B not
work.

.SH NOTES
This manual page is neither accurate nor complete. In particular, issues related to driver selection shall be described more accurately. Also the accurate sequence of autocommands execution, variables application is critical to understanding fim, and should be documented.
The filename "" is reserved for images read from standard input (view this as a limitation), and thus handling files with such name may incur in limitations.
The SDL driver is quite inefficient, for a variety of reasons. In particular, its interaction with the readline library can be problematic (e.g.: when running in sdl mode without a terminal). This shall be fixed.
.SH BUGS
\fBfim\fP has bugs. Please read the 
.B BUGS
file shipped in the documentation directory to discover the known ones.
There are also inconsistencies in the way the internal command line works across the different graphical devices.

.SH DESCRIPTION
This page explains the 
.B fim
language, which is used for the 
.B fimrc
configuration files, {scriptfile}s, or {commands} passed via command line {options}.
This language can be used to issue commands (or programs) from the internal program command line accessed interactively through the ":" key (or rather, the key code specified by the "\fB_console_key\fP" variable).
One may exit from command line mode by pressing the Enter key on an empty line (a non empty command line would be submitted for execution), or the Esc key  (only in SDL mode).
The general form of a fim command/program is shown in the next section.


.SH FIM LANGUAGE GRAMMAR
This section specifies the grammar of the 
.B fim
language.

Language elements surrounded by a single quote ("'") are literals.

Warning: at the present state, this grammar has conflicts. A future release shall fix them.

            | QUOTED_FLOAT
            | UNQUOTED_FLOAT
            | STRING

A STRING can be either a single quoted string or a double quoted string.
A floating point number can be either unquoted (UNQUOTED_FLOAT) or quoted (QUOTED_FLOAT).
A QUOTED_FLOAT is a floating point number, either single ("'") or double (""") quoted.
An INTEGER shall be an unsigned integer number.
An IDENTIFIER shall be one of the valid fim commands (see 
.B COMMANDS REFERENCE
) or a valid alias.
A VARIABLE shall be an already declared or undeclared variable identifier (see 
.B VARIABLES REFERENCE
) or a valid alias, created using the 
.B alias
command.
The "=~" operator treats the right expression as a STRING, and uses it as a regular expression for matching purposes.
The SLASH_AND_REGEXP is a slash ("/") followed by a STRING, interpreted as a regular expression.
If 'INTEGER , INTEGER IDENTIFIER arguments' is encountered, command IDENTIFIER will be repeated on each file in the interval between the two INTEGERs, and substituting the given file name to any '{}' found in the commands arguments (which must be quoted in order to be treated as strings).
See \fR\fIregex\fR(1) for regular expression syntax.

The way some one-line statements are evaluated:

.nf
:       enter command line mode
:{number}       jump to {number}^th image in the list
:^	        jump to first image in the list
:$	        jump to last image in the list
:*{factor}      scale the image by {factor}
:{scale}%       scale the image to the desired {scale}
:+{scale}%       scale the image up to the desired percentage {scale} (relatively to the original)
:-{scale}%       scale the image down to the desired percentage {scale} (relatively to the original)

/{regexp}		 entering the pattern {regexp} (with /) makes fim jump to the next image whose filename matches {regexp}
/*.png$		 entering this pattern (with /) makes fim jump to the next image whose filename ends with 'png'
/png		 a shortcut for /.*png.*

2,4 stdout '{}'	print three filenames to standard output.


!{syscmd}		executes the {syscmd} quoted string as an argument to the  "system" fim command.

If the sum is 0, no rotation will apply; if it is 1, a single ( 90') rotation will apply; if it is 2, a double (180') rotation will apply; if it is 3, a triple (270') rotation will apply.  If the sum is not one of 0,1,2,3, the value of the sum modulo 4 is considered.  Therefore, ":i:_orientation=1" and ":i:_orientation=5" are equivalent: they rotate the image one time by 90'.

.fi
.na
.B
_push_pushes_dirs

.SH NAME
fimgs \- poor man's [http://]PostScript/pdf/dvi/cbr/rar/cbz/zip viewer based on fim
.SH SYNOPSIS
.B fimgs [ {fimgs\-options} ] file [\-\- [{fim\-options}]]
.SH DESCRIPTION
.B fimgs  
is a wrapper script which takes a PostScript or pdf or .cbr or .rar or .cbz or .zip or .dvi or any of the above prefixed with http:// or https:// or ssh: as input, renders the pages using ghostscript into a temporary directory and finally calls \fB fim\fP to display them.

In case of compressed archives (in ZIP or RAR formats), the images are decompressed into a directory and displayed using \fB fim\fP.
In this case, only images contained in the archive will be displayed (no nested archives or pdf's or ps's or dvi's).

The temporary directory name will be of the form $TMPDIR/fbps\-$$.
If the $TMPDIR environment variable is unset, /dev/shm and /var/tmp will be checked for existence and permissions. 
The $$ above is the script process ID.
The script deletes the temporary directory when \fB fim\fP terminates.

In order to uncompress RAR archives, fimgs will use 'unrar\-nonfree' or 'rar' or 'unrar\-free'.

In order to uncompress ZIP archives, fimgs will use 'zip'.

In order to uncompress BZ2 files, 'bunzip2' will be used, if present.

In order to uncompress TAR.GZ or TAR.BZ2 or TAR.XZ archives, fimgs will use 'tar'.

In order to fetch http:// or https:// prefixed URLS, 'wget' will be used, if present.

In order to fetch ssh: prefixed host:path locations, 'scp' will be used.

In case of a CBZ, CBR, PDF, PS, or DVI file, will invoke \fB fim\fP with '\-\-autotop \-\-autowidth'.

.SH OPTIONS
To pass through options to \fB fim\fP, you may specify them after "\-\-".

Default options are '\-\-autozoom'.

.B \-r {resolution}
Specify resolution for the 'gs' \-r option (e.g.: 96x96; default 120x120). 
.TP

.B \-m
Dump a man page for fimgs.
.TP

.B \-p {password}
Specify password for the 'gs' \-p (password) option.
.TP

.B \-h
Will display a help message.
.\" Additionally you can specify \-l, \-xl or \-xxl to get the pages
.\" rendered with 100, 120 or 150 dpi (default is 75).

# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
#
# Of course, Automake must honor this variable whenever it calls a
# tool from the auxiliary directory.  The problem is that $srcdir (and
# therefore $ac_aux_dir as well) can be either absolute or relative,
# depending on how configure is run.  This is pretty annoying, since
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
# source directory, any form will work fine, but in subdirectories a
# relative path needs to be adjusted first.
#
# $ac_aux_dir/missing
#    fails when called from a subdirectory if $ac_aux_dir is relative
# $top_srcdir/$ac_aux_dir/missing
#    fails if $ac_aux_dir is absolute,
#    fails when called from a subdirectory in a VPATH build with
#          a relative $ac_aux_dir
#
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
# are both prefixed by $srcdir.  In an in-source build this is usually
# harmless because $srcdir is '.', but things will broke when you
# start a VPATH build or use an absolute $srcdir.
#
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
# and then we would define $MISSING as
#   MISSING="\${SHELL} $am_aux_dir/missing"
# This will work as long as MISSING is not called from configure, because
# unfortunately $(top_srcdir) has no meaning in configure.
# However there are other variables, like CC, which are often used in
# configure, and could therefore not use this "fixed" $ac_aux_dir.
#
# Another solution, used here, is to always expand $ac_aux_dir to an
# absolute PATH.  The drawback is that using absolute paths prevent a
# configured tree to be moved without reconfiguration.

Oops!

Your 'rm' program seems unable to run without file operands specified
on the command line, even when the '-f' option is present.  This is contrary
to the behaviour of most rm programs out there, and not conforming with
the upcoming POSIX standard: 

Please tell bug-automake@gnu.org about your system, including the value
of your $PATH and any error possibly output before this message.  This
can help us improve future automake versions.

Aborting the configuration process, to ensure you take notice of the issue.

You can download and install GNU coreutils to get an 'rm' implementation
that behaves properly: .

If you want to complete the configuration process using your problematic
'rm' anyway, export the environment variable ACCEPT_INFERIOR_RM_PROGRAM
to "yes", and re-run configure.

	  "Description: Make the code robust to the system's endianness
	  The code in src/b2ba.c was producing different results according
	  to the system being little or big-endian. Indeed, the variable
	  "byte" used for storing the value obtained by the read function
	  must be exactly one-byte long, otherwise the printf command will
	  output a "wrong" representation of the value in big-endian system
	  (for instance "0x36000000" instead iof "0x36"). This wrong
	  representation yielded compilation errors with g++ v6 in
	  big-endian sytems when file + default_font_byte_array.h was

	  a corrupt yacc.tab.hpp file. (See, for instance, this build log

	* [r450] THANKS, TODO, doc/fimrc.man, src/CommandConsole-help.cpp,

	  the ESC char. therefore the arrows did emit an ESC key, exiting
	  the command line.
	  fixing limiting the esc-exits-readline do SDL mode only.
	  a real fix would encompass a state machine and interpretation of
	  sequences of input chars, but this is a major feature.

## [	1		Overview](#1overview) ##
--------------------------------------------------------------------------------

FIM (Fbi IMproved) is a highly customizable and scriptable image viewer targeted
at the users who are comfortable with software like the Vim text editor or the
Mutt mail user agent, or keyboard oriented, full screen programs.
FIM aims to be a "Swiss Army knife" for viewing images.

FIM is multidevice: it has X support (via the SDL library), it supports
ASCII art output (via the aalib and libcaca libraries), and because it derives
from the Fbi image viewer (by Gerd Hoffmann), it can display images in the Linux
framebuffer console, too.

FIM is free software, distributed under the terms of the GPL software license.


## [	2		Description](#2description) ##
--------------------------------------------------------------------------------

FIM invocation is documented in `man fim` (/#man_fim).
The FIM language (syntax, commands, variables, key bindings) is documented in
 `man fimrc` (/#man_fimrc).

FIM offers many ways for scaling, orienting, listing or rearranging the
ordering of images.
FIM is capable of regular expressions based (on filename) vim-like autocommands,
comment-based search and filtering, display of EXIF tags, customizable command
lines, and use a custom font (from console fonts).
FIM offers GNU `readline` command line autocompletion and history,
completely customizable key bindings, internal/external scriptability
(through return codes, standard input/output, commands given at invocation time,
 and an initialization file), internal filename-based image search, and more.
Each documentation item is accessible via the internal `help` command.


## [	3		Features, comparison to other image viewers](#3features-comparison-to-other-image-viewers) ##
--------------------------------------------------------------------------------

Features:

 * modes: interactive (default), and command line
 * lots of the functionality is scripted in an internal domain specific language
 * on-screen debug and information console in command mode
 * per-image variables (e.g.: `i:var="value"`)
 * regular expression filename search (`/*.png`) and view
 * command line history (enter the console with `':'`, then use arrows)
 * command line Tab-based command autocompletion (thanks to the GNU readline)
 * command line history file save/load support (`~/.fim_history`)
 * key-action bindings, with Shift (uppercase and Control ('C-') key combinations
 * simple `if/while` scriptability, with integer/float/string variables and arithmetic evaluation
 * command aliases support (macros)
 * event autocommands (styled after Vim's `autocmd` )
 * regular expressions on filenames to enrich autocommand behaviour
 * image descriptions display ('expando' sequences)
 * regular expressions on image descriptions
 * configuration (initialization) file support (`~/.fimrc`)
 * usable built-in default configuration
 * wrapper script (`fimgs`) to convert pdf,ps,eps,dvi,cbr(rar),cbz(zip),tar,tar.gz,tgz,http://...
   contents into images that can be displayed
 * embedded piping through `convert`,`inkscape`,`xcftopnm`,`dia`... to visualize further file formats
 * view a Matrix Market file rendering via librsb
 * index-based `goto` styled after Vim (`:`)
 * image search with regular expressions on filenames (`goto` command)
 * other stuff   usual for an image viewer (`scale`, `pan,` etc..)
 * other stuff unusual for an image viewer (setting scale factor, auto width scale,
   auto height scale, marking of 'interesting' files, sorting of files in the
   list, recording/replaying of sessions, repeat last action )
 * image flip, mirror, rotation, stretch (asymmetric scaling)
 * command iteration (with the `[n]` syntax
 * external script file execution
 * system call support
 * image cache and mipmaps
 * image prefetch
 * pipe commands from an input program
 * many features could be enabled or disabled at compile time editing the Makefile
 * run under screen or ssh
 * read files list via standard input
 * read image file via standard input
 * read commands script via standard input
 * support for SDLlib (Simple Directmedia Layer) (`-o sdl`) (X!)
 * support for AAlib (ASCII Art rendering) (`-o aa`)
 * support for libcaca (Colour ASCII Art rendering) (`-o ca`)
 * experimental (incomplete, discouraged) support for Imlib2 (`-o imlib2`) (X!)
 * experimental support for file formats: PDF, PS, DJVU
 * view any file as a binary/RGB pixelmap
 * view any file as (rendered) text
 * open files at a specified byte offset
 * image list limiting (temporary list shrinking)
 * comments / captions / description files
 * search and reordering based on descriptions and internal variables
 * decode files based on magic number (contents), not file extension
 * recursive load from directory
 * sort files list on file name, file size or name date
 * text font control (selection of size and consolefont)
 * dump list of selected images to `stdout`
 * jump between last two images repeatedly with one key

 The next table is a comparison (very outdated...) of popular image viewers 
 available on Linux, focusing on FIM-like free software ones.

## [	4		Build, test, example](#4build-test-example) ##
--------------------------------------------------------------------------------


Requirements are:

 * the GNU readline library ( https://www.gnu.org/software/readline/ )
 * GNU flex  (NOT any lex ) ( https://www.gnu.org/software/flex/  )
   (some systems need also 'libfl-dev'  to find `FlexLexer.h`)
 * GNU bison (NOT any yacc) ( https://www.gnu.org/software/bison/)
 * the GCC ( GNU Compiler Collection ) ( http://gcc.gnu.org/ )
   or clang ( https://clang.llvm.org/ )
 * and optionally:
	* libsdl-1.2		  ( http://libsdl.org/ )
	* libsdl-2.0		  ( http://libsdl.org/ )
	* libexif		  ( https://libexif.github.io/ )
	* libjpeg		  ( http://www.ijg.org/ )
	* libpng		  ( http://www.libpng.org/ )
	* giflib		  ( http://sourceforge.net/projects/giflib/ )
	* libtiff		  ( http://www.libtiff.org/ )
	* libdjvulibre	  ( https://djvu.sourceforge.net/ )
	* ...


 Libraries originally required by Fbi-1.31 but not by FIM:
 	libFS, libCURL, libLIRC


Usually, building and installing FIM proceeds like:

	./configure --help # get options you may pass to configure
	./configure
	make
	make test
	sudo make install

If you wish to run `./configure` again with different options, it is
recommended to `make clean` before that.

--------------------------------------------------------------------------------
## [	4.1		Test](#41test) ##

 
	# run fim in interactive mode (press q to quit)
	make test

	# run the test suite
	make tests


You can also run separately parts of `make tests`:

	# run only -o fbdev tests (if disabled, fail)
	make fbtests

	# run only -o sdl tests (if disabled, fail)
	make sdltests

	# run only -o aa tests (if disabled, fail)
	make aatests

	# run only -o ca tests (if disabled, fail)
	make cacatests

--------------------------------------------------------------------------------
## [	4.2		Example on Debian](#42example-on-debian) ##

	sudo apt-get install subversion
	sudo apt-get install flex libfl-dev bison
	sudo apt-get install automake autoconf libtool # to generate configure, etc
	sudo apt-get install pkg-config                # to generate configure
	sudo apt-get install libreadline-dev libexif-dev
	sudo apt-get install libjpeg-dev libpng-dev libtiff-dev libgif-dev
	sudo apt-get install libsdl2-dev libaa1-dev libcaca-dev
	# experimental, not recommended:
	sudo apt-get install libpoppler-dev libdjvulibre-dev libspectre-dev
	sudo apt-get install libarchive-dev
	svn co http://svn.savannah.nongnu.org/svn/fbi-improved/trunk/ fim
	cd fim
	autoreconf -i
	./configure --enable-aa --enable-caca --enable-sdl
	make
	sudo make install
 

## [	5		Run time requirements](#5run-time-requirements) ##
--------------------------------------------------------------------------------

 * Linux (not sure if it is necessary for it to be an x86; i think not)
 * The framebuffer device ( e.g.: `/dev/fb0` or `/dev/fb/0` ) enabled in the kernel
   ( and usually found in `"/usr/src/linux/Documentation/fb"` in the kernel source
    code tree ).
 * unless disabled, FIM will create a history (`~/.fim_history`) file in the
    `${HOME}` directory when leaving (so it assumes ${HOME} to exist)
 * shared library files for e.g.: libpng, libjpeg, libgif, libtiff, libreadline,
   libexif, ...


## [	6		Original Idea](#6original-idea) ##
--------------------------------------------------------------------------------

FIM derives from the wonderful fbi-1.31, written by Gerd Hoffmann/Knorr:
 ( Fbi can be obtained at https://www.kraxel.org/blog/linux/fbida/ ).

It all started in 2005, developing a small 'vim-like fbi patch', and following
features to enrich Fbi with a command line and more customizations.

FIM is a significant reorganization and expansion of the Fbi code, and aims at
obtaining the most scriptable and configurable image viewer ever.


## [	7		Notes for patch writers](#7notes-for-patch-writers) ##
--------------------------------------------------------------------------------

To run, FIM requires a Linux box with X, or the framebuffer device enabled in
the kernel, and some popular image file decoding libraries.

Information about the framebuffer can be found under the directory
 "./Documentation/fb"
 inside the kernel tree 
 (usually "/usr/src/linux/Documentation/fb" ).

The file decoding libraries are listed in an earlier section.
Tested and working with library SDL-1.2.12 through SDL-1.2.15.
Experimental support for SDL-2.0.

From the original Fbi README, it reads that Gerd himself built FBI hacking
"a svgalib PhotoCD viewer", so regard this software as a big, dirty code
potpourri :) .
For the sake of completeness, FIM started as a fork of version 1.31 of fbi,
available from http://dl.bytesex.org/releases/fbida/fbi_1.31.tar.gz .

 If you intend to write patches or contribute to the code, be sure of reading 
 all of the documentation and _write me an email first_ (I will give you some
 advice).


--------------------------------------------------------------------------------
## [	7.1		Hacking, maintenance guidelines](#71hacking-maintenance-guidelines) ##

If you hack FIM in an interesting way, consider submitting your changes as a
patch.

 * If you introduce support for a new file format: `fim -V` should list the
   your new format, too (so you should update it).
 * Same for a new output device.
 * FIM should continue passing the tests after your patch, and your patch should
   be robust, too. Consider writing a new test case.


## [	8		Availability in Linux distributions](#8availability-in-linux-distributions) ##
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
## [	8.1		Debian, Ubuntu](#81debian-ubuntu) ##
 
 You should find fim in Debian and Ubuntu, and install it with:

	sudo apt-get install fim

 But beware: the deb packages may be outdated.
 

 In order to build from repository, you are advised to install packages from
 the following (overly complete) list:
  
 autoconf autoconf-archive autoheader automake autotools-dev bison ctags
 flex groff g++ libaa1-dev libcaca-dev libdjvulibre-dev libgif4 libgif-dev
 libjpeg-dev libncurses5-dev libpng-dev libpoppler-cpp-dev libpoppler-dev
 libreadline-dev libsdl2-dev libspectre-dev libtiff-dev libtool m4 make svn
 txt2html libexif-dev

 The above list was valid on a Debian Jessie installation; it's possible that
 these packages names change with time.

	1		Overview
================================================================================

FIM (Fbi IMproved) is a highly customizable and scriptable image viewer targeted
at the users who are comfortable with software like the Vim text editor or the
Mutt mail user agent, or keyboard oriented, full screen programs.
FIM aims to be a "Swiss Army knife" for viewing images.

FIM is multidevice: it has X support (via the SDL library), it supports
ASCII art output (via the aalib and libcaca libraries), and because it derives
from the Fbi image viewer (by Gerd Hoffmann), it can display images in the Linux
framebuffer console, too.

FIM is free software, distributed under the terms of the GPL software license.

-==============================================================================-
	2		Description
================================================================================

FIM invocation is documented in `man fim` (doc/fim.man.html).
The FIM language (syntax, commands, variables, key bindings) is documented in
 `man fimrc` (doc/fimrc.man.html).

FIM offers many ways for scaling, orienting, listing or rearranging the
ordering of images.
FIM is capable of regular expressions based (on filename) vim-like autocommands,
comment-based search and filtering, display of EXIF tags, customizable command
lines, and use a custom font (from console fonts).
FIM offers GNU `readline` command line autocompletion and history,
completely customizable key bindings, internal/external scriptability
(through return codes, standard input/output, commands given at invocation time,
 and an initialization file), internal filename-based image search, and more.
Each documentation item is accessible via the internal `help` command.

-==============================================================================-
	3		Features, comparison to other image viewers
================================================================================

Features:

 * modes: interactive (default), and command line
 * lots of the functionality is scripted in an internal domain specific language
 * on-screen debug and information console in command mode
 * per-image variables (e.g.: `i:var="value"`)
 * regular expression filename search (`/*.png`) and view
 * command line history (enter the console with `':'`, then use arrows)
 * command line Tab-based command autocompletion (thanks to the GNU readline)
 * command line history file save/load support (`~/.fim_history`)
 * key-action bindings, with Shift (uppercase and Control ('C-') key combinations
 * simple `if/while` scriptability, with integer/float/string variables and arithmetic evaluation
 * command aliases support (macros)
 * event autocommands (styled after Vim's `autocmd` )
 * regular expressions on filenames to enrich autocommand behaviour
 * image descriptions display ('expando' sequences)
 * regular expressions on image descriptions
 * configuration (initialization) file support (`~/.fimrc`)
 * usable built-in default configuration
 * wrapper script (`fimgs`) to convert pdf,ps,eps,dvi,cbr(rar),cbz(zip),tar,tar.gz,tgz,http://...
   contents into images that can be displayed
 * embedded piping through `convert`,`inkscape`,`xcftopnm`,`dia`... to visualize further file formats
 * view a Matrix Market file rendering via librsb
 * index-based `goto` styled after Vim (`:`)
 * image search with regular expressions on filenames (`goto` command)
 * other stuff   usual for an image viewer (`scale`, `pan,` etc..)
 * other stuff unusual for an image viewer (setting scale factor, auto width scale,
   auto height scale, marking of 'interesting' files, sorting of files in the
   list, recording/replaying of sessions, repeat last action )
 * image flip, mirror, rotation, stretch (asymmetric scaling)
 * command iteration (with the `[n]` syntax
 * external script file execution
 * system call support
 * image cache and mipmaps
 * image prefetch
 * pipe commands from an input program
 * many features could be enabled or disabled at compile time editing the Makefile
 * run under screen or ssh
 * read files list via standard input
 * read image file via standard input
 * read commands script via standard input
 * support for SDLlib (Simple Directmedia Layer) (`-o sdl`) (X!)
 * support for AAlib (ASCII Art rendering) (`-o aa`)
 * support for libcaca (Colour ASCII Art rendering) (`-o ca`)
 * experimental (incomplete, discouraged) support for Imlib2 (`-o imlib2`) (X!)
 * experimental support for file formats: PDF, PS, DJVU
 * view any file as a binary/RGB pixelmap
 * view any file as (rendered) text
 * open files at a specified byte offset
 * image list limiting (temporary list shrinking)
 * comments / captions / description files
 * search and reordering based on descriptions and internal variables
 * decode files based on magic number (contents), not file extension
 * recursive load from directory
 * sort files list on file name, file size or name date
 * text font control (selection of size and consolefont)
 * dump list of selected images to `stdout`
 * jump between last two images repeatedly with one key

 The next table is a comparison (very outdated...) of popular image viewers 
 available on Linux, focusing on FIM-like free software ones.

	4		Build, test, example
================================================================================


Requirements are:

 * the GNU readline library ( https://www.gnu.org/software/readline/ )
 * GNU flex  (NOT any lex ) ( https://www.gnu.org/software/flex/  )
   (some systems need also 'libfl-dev'  to find `FlexLexer.h`)
 * GNU bison (NOT any yacc) ( https://www.gnu.org/software/bison/)
 * the GCC ( GNU Compiler Collection ) ( http://gcc.gnu.org/ )
   or clang ( https://clang.llvm.org/ )
 * and optionally:
	* libsdl-1.2		  ( http://libsdl.org/ )
	* libsdl-2.0		  ( http://libsdl.org/ )
	* libexif		  ( https://libexif.github.io/ )
	* libjpeg		  ( http://www.ijg.org/ )
	* libpng		  ( http://www.libpng.org/ )
	* giflib		  ( http://sourceforge.net/projects/giflib/ )
	* libtiff		  ( http://www.libtiff.org/ )
	* libdjvulibre	  ( https://djvu.sourceforge.net/ )
	* ...


 Libraries originally required by Fbi-1.31 but not by FIM:
 	libFS, libCURL, libLIRC


Usually, building and installing FIM proceeds like:

	./configure --help # get options you may pass to configure
	./configure
	make
	make test
	sudo make install

If you wish to run `./configure` again with different options, it is
recommended to `make clean` before that.

--------------------------------------------------------------------------------
	4.1		Test

 
	# run fim in interactive mode (press q to quit)
	make test

	# run the test suite
	make tests


You can also run separately parts of `make tests`:

	# run only -o fbdev tests (if disabled, fail)
	make fbtests

	# run only -o sdl tests (if disabled, fail)
	make sdltests

	# run only -o aa tests (if disabled, fail)
	make aatests

	# run only -o ca tests (if disabled, fail)
	make cacatests

--------------------------------------------------------------------------------
	4.2		Example on Debian

	sudo apt-get install subversion
	sudo apt-get install flex libfl-dev bison
	sudo apt-get install automake autoconf libtool # to generate configure, etc
	sudo apt-get install pkg-config                # to generate configure
	sudo apt-get install libreadline-dev libexif-dev
	sudo apt-get install libjpeg-dev libpng-dev libtiff-dev libgif-dev
	sudo apt-get install libsdl2-dev libaa1-dev libcaca-dev
	# experimental, not recommended:
	sudo apt-get install libpoppler-dev libdjvulibre-dev libspectre-dev
	sudo apt-get install libarchive-dev
	svn co http://svn.savannah.nongnu.org/svn/fbi-improved/trunk/ fim
	cd fim
	autoreconf -i
	./configure --enable-aa --enable-caca --enable-sdl
	make
	sudo make install
 
-==============================================================================-
	5		Run time requirements
================================================================================

 * Linux (not sure if it is necessary for it to be an x86; i think not)
 * The framebuffer device ( e.g.: `/dev/fb0` or `/dev/fb/0` ) enabled in the kernel
   ( and usually found in `"/usr/src/linux/Documentation/fb"` in the kernel source
    code tree ).
 * unless disabled, FIM will create a history (`~/.fim_history`) file in the
    `${HOME}` directory when leaving (so it assumes ${HOME} to exist)
 * shared library files for e.g.: libpng, libjpeg, libgif, libtiff, libreadline,
   libexif, ...

-==============================================================================-
	6		Original Idea
================================================================================

FIM derives from the wonderful fbi-1.31, written by Gerd Hoffmann/Knorr:
 ( Fbi can be obtained at https://www.kraxel.org/blog/linux/fbida/ ).

It all started in 2005, developing a small 'vim-like fbi patch', and following
features to enrich Fbi with a command line and more customizations.

FIM is a significant reorganization and expansion of the Fbi code, and aims at
obtaining the most scriptable and configurable image viewer ever.

-==============================================================================-
	7		Notes for patch writers
================================================================================

To run, FIM requires a Linux box with X, or the framebuffer device enabled in
the kernel, and some popular image file decoding libraries.

Information about the framebuffer can be found under the directory
 "./Documentation/fb"
 inside the kernel tree 
 (usually "/usr/src/linux/Documentation/fb" ).

The file decoding libraries are listed in an earlier section.
Tested and working with library SDL-1.2.12 through SDL-1.2.15.
Experimental support for SDL-2.0.

From the original Fbi README, it reads that Gerd himself built FBI hacking
"a svgalib PhotoCD viewer", so regard this software as a big, dirty code
potpourri :) .
For the sake of completeness, FIM started as a fork of version 1.31 of fbi,
available from http://dl.bytesex.org/releases/fbida/fbi_1.31.tar.gz .

Useful documents I've read and consulted during the coding of Fim, and 
useful for hacking it:

 * Thomas Niemann's tutorial to yacc & lex
 * The yacc & lex HOWTO
 * GNU readline manual

--------------------------------------------------------------------------------
	7.1		Hacking, maintenance guidelines

If you hack FIM in an interesting way, consider submitting your changes as a
patch.

 * If you introduce support for a new file format: `fim -V` should list the
   your new format, too (so you should update it).
 * Same for a new output device.
 * FIM should continue passing the tests after your patch, and your patch should
   be robust, too. Consider writing a new test case.

	8		Availability in Linux distributions
================================================================================

--------------------------------------------------------------------------------
	8.1		Debian, Ubuntu
 
 You should find fim in Debian and Ubuntu, and install it with:

	sudo apt-get install fim

 But beware: the deb packages may be outdated.
 

 In order to build from repository, you are advised to install packages from
 the following (overly complete) list:
  
 autoconf autoconf-archive autoheader automake autotools-dev bison ctags
 flex groff g++ libaa1-dev libcaca-dev libdjvulibre-dev libgif4 libgif-dev
 libjpeg-dev libncurses5-dev libpng-dev libpoppler-cpp-dev libpoppler-dev
 libreadline-dev libsdl2-dev libspectre-dev libtiff-dev libtool m4 make svn
 txt2html libexif-dev

 The above list was valid on a Debian Jessie installation; it's possible that
 these packages names change with time.

/* Avoiding alloca during matching, to placate r_alloc.  */

/* Define MATCH_MAY_ALLOCATE unless we need to make sure that the
   searching and matching functions should not call alloca.  On some
   systems, alloca is implemented in terms of malloc, and if we're
   using the relocating allocator routines, then malloc could cause a
   relocation, which might (if the strings being searched are in the
   ralloc heap) shift the data out from underneath the regexp
   routines.

   Here's another reason to avoid allocation: Emacs
   processes input from X in a signal handler; processing X input may
   call malloc; if input arrives while a matching routine is calling
   malloc, then we're scrod.  But Emacs can't just block input while
   calling matching routines; then we don't notice interrupts when
   they come in.  So, Emacs blocks input around all regexp calls
   except the matching calls, which it leaves unprotected, in the
   faith that they will not malloc.  */

.TH fimgs 1 "(c) 2007-2023 Michele Martone"
.SH NAME
fimgs - poor man's [http://]PostScript/pdf/dvi/cbr/rar/cbz/zip viewer based on fim
.SH SYNOPSIS
.B fimgs [ {fimgs-options} ] file [-- [{fim-options}]]
.SH DESCRIPTION
.B fimgs  
is a wrapper script which takes a PostScript or pdf or .cbr or .rar or .cbz or .zip or .dvi or any of the above prefixed with http:// or https:// or ssh: as input, renders the pages using ghostscript into a temporary directory and finally calls \fB $FBI\fP to display them.

In case of compressed archives (in ZIP or RAR formats), the images are decompressed into a directory and displayed using \fB fim\fP.
In this case, only images contained in the archive will be displayed (no nested archives or pdf's or ps's or dvi's).

The temporary directory name will be of the form \$TMPDIR/$FIMTDPFX-\$\$.
If the \$TMPDIR environment variable is unset, $FIMSHMEM and $FIMVARTD will be checked for existence and permissions. 
The \$\$ above is the script process ID.
The script deletes the temporary directory when \fB fim\fP terminates.

In order to uncompress RAR archives, fimgs will use 'unrar-nonfree' or 'rar' or 'unrar-free'.

In order to uncompress ZIP archives, fimgs will use 'zip'.

In order to uncompress BZ2 files, 'bunzip2' will be used, if present.

In order to uncompress TAR.GZ or TAR.BZ2 or TAR.XZ archives, fimgs will use 'tar'.

In order to fetch http:// or https:// prefixed URLS, 'wget' will be used, if present.

In order to fetch ssh: prefixed host:path locations, 'scp' will be used.

In case of a CBZ, CBR, PDF, PS, or DVI file, will invoke \fB fim\fP with '$fbi_read_opts'.

.SH OPTIONS
To pass through options to \fB fim\fP, you may specify them after "--".

Default options are '$fbi_default_opts'.

.B -r {resolution}
Specify resolution for the 'gs' -r option (e.g.: 96x96; default $GSRESOLUTION). 
.TP

.B -m
Dump a man page for fimgs.
.TP

.B -p {password}
Specify password for the 'gs' -p (password) option.
.TP

.B -h
Will display a help message.
.\" Additionally you can specify -l, -xl or -xxl to get the pages
.\" rendered with 100, 120 or 150 dpi (default is 75).

 .TP
 .B -f font
 Set font.  This can be either a pcf console font file or a X11 font
 spec.  Using X11 fonts requires a font server (The one specified in
 the environment variable FONTSERVER or on localhost).  The FBFONT
 environment variable is used as default.  If unset, fim will
 fallback to 10x20 (X11) / lat1u-16.psf (console).
 .TP
 .B --autoup
 Like autozoom, but scale up only.
 .TP
 .B --autodown
 Like autozoom, but scale down only.
 .TP
 .B -u
 Randomize the order of the filenames.
 .TP
 .B -e
 Enable editing commands.
 .TP
 .B -b
 create backup files (when editing images).
 .TP
 .B -p
 preserve timestamps (when editing images).
 .TP
 .B --comments
 Display comment tags (if present) instead of the filename.  Probaby
 only useful if you added reasonable comments yourself (using wrjpgcom
 for example), otherwise you likely just find texts pointing to the
 software which created the image.
 P               pause the slideshow (if started with -t, toggle)
 {number}g    jump to image {number}
 .SH EDIT IMAGE
 fim also provides some very basic image editing facilities.  You have
 to start fim with the -e switch to use them.
 .P
 .nf
 Shift+D         delete image
 R               rotate 90 degrees clockwise
 L               rotate 90 degrees counter-clock wise
 .fi
 .P
 The delete function actually wants a capital letter 'D', thus you have
 to type Shift+D.  This is done to avoid deleting images by mistake
 because there are no safety bells:  If you ask fim to delete the image,
 it will be deleted without questions asked.
 .P
 The rotate function actually works for JPEG images only because it
 calls the jpegtran command to perform a lossless rotation if the image.
 It is especially useful if you review the images of your digital
 camera.

			".B\nfim\nis a `swiss army knife' for displaying image files.\n"
			"It is capable of displaying image files using different graphical devices while offering a uniform look and feel.\n"
			"Key bindings are customizable and specified in an initialization file.\n"
			"Interaction with standard input and output is possible (especially in shell scripts).\n"
			"An internal scripting language specialized for image viewing allows image navigation, scaling, manipulation of internal variables, command aliases, and vim-like autocommands.\n"
			"The internal language can be interacted with via a command line mode capable of autocompletion and history (the readline mode).\n"
			"Further features are display of EXIF tags, JPEG comments, EXIF rotation/orientation, load of \"description files\", faster load via image caching, command recording, and much more.\n\n"
			"As a default,\n.B\nfim\ndisplays the specified file(s) on the detected, most convenient graphical device. "
			"This can be with SDL if running under X, an Ascii Art driver (aalib or libcaca) if running behind ssh without X forwarding, or the linux framebuffer device. "
			"Graphical file formats " FIM_CNS_DSFF_SN " are supported natively, while " FIM_CNS_DSFF_SL " are supported via third party libraries. \n"
			"Further formats are supported via external converters. \n"
			"For XCF (Gimp's) images, will try to use '" FIM_EPR_XCFTOPNM "'.\nFor FIG vectorial images, will try to use '" FIM_EPR_FIG2DEV "'.\nFor DIA vectorial images, will try to use '" FIM_EPR_DIA "'.\nFor SVG vectorial images, will try to use '" FIM_EPR_INKSCAPE "'.\nFor other formats will try to use ImageMagick's '" FIM_EPR_CONVERT "' executable.\n"
