But its xterm emulation is not completely accurate, and it so happens that VBinDiff triggers the problem. When using VBinDiff with the "xterm" terminal type, you'll notice that the background color doesn't extend to the right edge of the screen. (Also, the Home and End keys don't work.) To fix this, you must tell PuTTY to stop pretending it's an xterm. To do that, go to the PuTTY Configuration dialog, and find the Data page (under Connection). Change the Terminal-type string from "xterm" to "putty". Don't forget to save your settings after making this change. This brings us to the second problem. The terminal description for PuTTY distributed with ncurses 5.4 misidentifies the Home and End keys as Find and Select, respectively. That means those keys won't work in VBinDiff (or other programs, for that matter). To fix this, you can get the latest terminfo file from the author of ncurses (Thomas Dickey) and install it: ftp://invisible-island.net/ncurses/terminfo.src.gz Or, for your convenience, I have included the corrected terminfo record with VBinDiff in the file putty.src. To install it (on the system running VBinDiff), simply type: tic putty.src If you do that as root, it will update the system terminfo database with the corrected record. Otherwise, it will install the record in your home directory (under ~/.terminfo). vbindiff-3.0_beta5/missing0000755000175000017500000001533113155330040012540 00000000000000#! /bin/sh # Common wrapper for a few potentially missing GNU programs. scriptversion=2012-06-26.16; # UTC # Copyright (C) 1996-2013 Free Software Foundation, Inc. # Originally written by Fran,cois Pinard , 1996. # 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, 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.

Madsen CONTENTS ======== [1] About Visual Binary Diff [2] System Requirements [3] Installation [4] License [5] Author [1] About Visual Binary Diff ---------------------------- Visual Binary Diff (VBinDiff) displays files in hexadecimal and ASCII (or EBCDIC). It can also display two files at once, and highlight the differences between them. Unlike diff, it works well with large files (up to 4 GB). VBinDiff was inspired by the Compare Files function of the ProSel utilities by Glen Bredon, for the Apple II. When I couldn't find a similar utility for the PC, I wrote it myself. The single-file mode was inspired by the LIST utility of 4DOS and friends (http://www.jpsoft.com/4ntdes.htm). While less (http://www.greenwoodsoftware.com/less/) provides a good line-oriented display, it has no equivalent to LIST's hex display. (True, you can pipe the file through hexdump, but that's incredibly inefficient on multi-gigabyte files.) [2] System Requirements ----------------------- Windows 95, Windows NT 4.0, or later or A POSIX-compatible system with ncurses (eg, Linux) It should be possible to port the ncurses version to work with other curses libraries (as long as they provide the panel library), but I don't have access to such a system. Patches are welcome. [3] Installation ---------------- VBinDiff uses the standard GNU autoconf system. See the file INSTALL if you're not familiar with that.

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.

Madsen [% ELSE %] vbindiff - hexadecimal file display and comparison [% END %] =head1 SYNOPSIS B I [ I ] =head1 DESCRIPTION Visual Binary Diff (VBinDiff) displays files in hexadecimal and ASCII (or EBCDIC). It can also display two files at once, and highlight the differences between them. Unlike B, it works well with large files (up to 4 GB). =head2 Viewing files Movement Keys ------------- Up Move one line (16 bytes) towards the beginning of the file Down Move one line (16 bytes) towards the end of the file Left Move one byte towards the beginning of the file Right Move one byte towards the end of the file PageUp Move one page towards the beginning of the file PageDn Move one page towards the end of the file Home Move to the beginning of the file End Move to the end of the (shorter) file F Search for a string or byte sequence G Move to a specified file position When displaying two files, both files move together. If bytes have been added or removed in one of the files, you can adjust the comparison by moving just one of the files. [% IF Win32 %] Holding down Alt while using the movement keys will scroll only the bottom file. Holding down Ctrl will scroll only the top file. [% ELSE %] To move only the top file, press C. To move only the bottom file, press C. To return to moving both files, press the same key again. (The window at the bottom of the screen will indicate when you are moving only one file.) [% END %] Other Keys ---------- Enter Move to the next difference between the files Space (same as Enter) C Toggle between ASCII and EBCDIC display E Edit currently displayed section of file Esc Exit VBinDiff Q Exit VBinDiff The C key will advance to the next difference between the files (after those already displayed on the screen). If there are no more differences, it moves to the end. =head2 Line editor The line editor is used to enter search strings and file positions. It uses the basic Emacs-style editing keys. Keys ----------------- Ctrl-B, Left Move the cursor one character left Ctrl-F, Right Move the cursor one character right Ctrl-A, Home Move to the beginning of the line Ctrl-E, End Move to the end of the line Ctrl-P, Up Move up in input history Ctrl-N, Down Move down in input history Ctrl-H, Backspace Delete the character to the left Ctrl-D, Delete Delete the character under the cursor Ctrl-K Delete from cursor to end of line Insert Toggle between insert & overstrike mode Enter Finished entering text Esc Abort the operation =head2 Editing files You can press C to edit the current file. When displaying two files, this edits the one in the top window[% IF Win32 %] . Press C to edit the file in the bottom window. [% ELSE %] , unless you are in "move bottom" mode. [% END %] When editing, you can move the cursor around with the arrow keys. Use TAB to switch between entering hexadecimal or ASCII (or EBCDIC) characters. Press the Esc key when you are done. You will be given the choice to save or discard your changes then. If you are displaying two files, you can use the Enter key to copy a byte from the other file into the one you are editing. You cannot scroll through the file while editing, although you can save your changes and then move to a different part of the file. Also, you cannot insert or delete bytes, only change them. =head1 OPTIONS -L, --license Display license information for vbindiff -V, --version Display the version number --help Display help information =head1 BUGS Does not work properly with files over 4 gigabytes. It should be able to view the first 4 gigabytes ok, but the display only has room for 8 hex digits of file position, and the Goto box is also limited to 8 digits. =head1 LICENSE VBinDiff 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.

It can also display two files at once, and highlight the differences between them. Unlike diff, it works well with large files (up to 4 GB). VBinDiff was inspired by the Compare Files function of the ProSel utilities by Glen Bredon, for the Apple II. When I couldn't find a similar utility for the PC, I wrote it myself. The single-file mode was inspired by the LIST utility of 4DOS and friends (http://www.jpsoft.com/4ntdes.htm). While less (http://www.greenwoodsoftware.com/less/) provides a good line-oriented display, it has no equivalent to LIST's hex display. (True, you can pipe the file through hexdump, but that's incredibly inefficient on multi-gigabyte files.) [% section('System Requirements') %] Windows 95, Windows NT 4.0, or later or A POSIX-compatible system with ncurses (eg, Linux) It should be possible to port the ncurses version to work with other curses libraries (as long as they provide the panel library), but I don't have access to such a system. Patches are welcome. [% section('Installation') %] [% IF Win32 %] Copy VBinDiff.exe to a folder on your path. If you don't know what a path is, you can put it in your C:\Windows directory. Then read VBinDiff.txt to find out how to use it. [% ELSE %] VBinDiff uses the standard GNU autoconf system. See the file INSTALL if you're not familiar with that.

If bytes have been added or removed in one of the files, you can adjust the comparison by moving just one of the files. To move only the top file, press \f(CW\*(C`T\*(C'\fR. To move only the bottom file, press \f(CW\*(C`B\*(C'\fR. To return to moving both files, press the same key again.

If there are no more differences, it moves to the end. .SS "Line editor" .IX Subsection "Line editor" The line editor is used to enter search strings and file positions. It uses the basic Emacs-style editing keys. .PP .Vb 10 \& Keys \& \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- \& Ctrl\-B, Left Move the cursor one character left \& Ctrl\-F, Right Move the cursor one character right \& Ctrl\-A, Home Move to the beginning of the line \& Ctrl\-E, End Move to the end of the line \& Ctrl\-P, Up Move up in input history \& Ctrl\-N, Down Move down in input history \& Ctrl\-H, Backspace Delete the character to the left \& Ctrl\-D, Delete Delete the character under the cursor \& Ctrl\-K Delete from cursor to end of line \& Insert Toggle between insert & overstrike mode \& Enter Finished entering text \& Esc Abort the operation .Ve .SS "Editing files" .IX Subsection "Editing files" You can press \f(CW\*(C`E\*(C'\fR to edit the current file. When displaying two files, this edits the one in the top window, unless you are in \*(L"move bottom\*(R" mode. .PP When editing, you can move the cursor around with the arrow keys. Use \&\s-1TAB\s0 to switch between entering hexadecimal or \s-1ASCII \s0(or \s-1EBCDIC\s0) characters. Press the Esc key when you are done. You will be given the choice to save or discard your changes then. .PP If you are displaying two files, you can use the Enter key to copy a byte from the other file into the one you are editing. .PP You cannot scroll through the file while editing, although you can save your changes and then move to a different part of the file.

Here's ## why we pick this rather obscure method: ## - Don't want to use -MD because we'd like the dependencies to end ## up in a subdir. Having to rename by hand is ugly. ## (We might end up doing this anyway to support other compilers.) ## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like ## -MM, not -M (despite what the docs say). Also, it might not be ## supported by the other compilers which use the 'gcc' depmode. ## - Using -M directly means running the compiler twice (even worse ## than renaming). if test -z "$gccflag"; then gccflag=-MD, fi "$@" -Wp,"$gccflag$tmpdepfile" stat=$? if test $stat -ne 0; then rm -f "$tmpdepfile" exit $stat fi rm -f "$depfile" echo "$object : \\" > "$depfile" # The second -e expression handles DOS-style file names with drive # letters. sed -e 's/^[^:]*: / /' \ -e 's/^['$alpha']:\/[^:]*: / /' < "$tmpdepfile" >> "$depfile" ## This next piece of magic avoids the "deleted header file" problem. ## The problem is that when a header file which appears in a .P file ## is deleted, the dependency causes make to die (because there is ## typically no way to rebuild the header). We avoid this by adding ## dummy dependencies for each header file. Too bad gcc doesn't do ## this for us directly. ## Some versions of gcc put a space before the ':'. On the theory ## that the space means something, we add a space to the output as ## well. hp depmode also adds that space, but also prefixes the VPATH ## to the object. Take care to not repeat it in the output. ## Some versions of the HPUX 10.20 sed can't process this invocation ## correctly.
