There seems to be some bug (or disagreement) between embryo and gcc 3.2.x where IEEE floating point format encoding does not "agree" with embryo's own hand-made tests. embryo_cc may not work if you compile using gcc 3.2.x. gcc 3.3.x is known to work fine. we are not 100% sure whose fault this is yet, so we won't be jumping up and down, but be warned - gcc 3.2.x does not agree with embryo. To view the API docs, run ./gendoc and view doc/html/index.html. OK a lot of people ask this. What is Embryo? Embryo is primarily a shared library that gives you an API to load and control interpreted programs compiled into an abstract machine bytecode that it understands. This abstract (or virtual) machine is similar to a real machine with a CPU, but it is emulated in software. The architecture is simple and is the same as the abstract machine (AMX) in the PAWN language (formerly called SMALL) as it is based on exactly the same code. Embryo has modified the code for the AMX extensively and has made it smaller and more portable. It is VERY small. The total size of the virtual machine code AND header files is less than 2500 lines of code. It includes the floating point library support by default as well. This makes it one of the smallest interpreters around, and thus makes is very efficient to use in code. Embryo also uses the PAWN compiler from the same code base. This code has barely been touched and so suffers from lots of portability issues. It has been partially fixed and now works on both big and little endian but the code still need to be gone over and really cleaned up . It does work, but it's only just working. It has been called embryo_cc and compiled a subset of PAWN binary outputs. It does not support packed strings, variable alignment, or debugging output. It does not support many features of the full PAWN compiler because the Embryo AMX does not support these either. You will find the Embryo codebase to work much better on Linux (and BSD and MacOS X) and other UNIX operating systems as it has been developed and tested on them. IT is known to work on: gcc Linux (x86-32) gcc Linux (PPC) gcc MacOS X (PPC) And will likely work on more combinations. IT currently has problems on 64bit SPARC CPUs. Other 64bit systems are untested. It is the aim to fix the code so it works on all commonly used architectures (32, 64bit, big and little endian, alignment forgiving/unforgiving). So far 64bit support is the major issue. For more documentation please see the Language guide here: Pawn Language Booklet This documents the PAWN language and is 100% relevant for Embryo and the syntax of files it can compile (.sma files). Any help is appreciated in helping clean and port this code, so feel free to send patches to the Enlightenment development lists. The main aim of Embryo is to provide an easy to use library for running compiled PAWN programs and giving them access to the calling program and any API it exports to the PAWN script. PAWN programs/scripts are completely sand-boxed. They cannot access any system or function calls other than the ones provided by the calling application to the Embryo API. This means a PAWN script cannot open or write to, delete or load files. It is fairly harmless and this also keeps Embryo small. This is a work in progress, so please be patient if things don't work for you - and patches and help in fixing it is very much appreciated. ------------------------------------------------------------------------------ COMPILING AND INSTALLING: ./configure make (as root unless you are installing in your users directories): make install embryo-1.7.7/ChangeLog0000664000175000017500000000300112127363552011520 000000000000002011-01-29 Carsten Haitzler (The Rasterman) 1.0.0 release 2011-05-12 Carsten Haitzler (The Rasterman) * Make embryo_cc use eina and eina_prefix to determine include location 2011-07-16 Vincent Torri * delete temporary files on Windows 2011-10-05 Vincent Torri * use fseek() instead of rewind() as the latter does not exist on Windows CE and fix compilation with Evil. 2011-12-02 Carsten Haitzler (The Rasterman) 1.1.0 release 2012-02-24 Cedric Bail * Add exotic support 2012-03-07 Vincent Torri * Fix windows compilation issues 2012-04-16 Carsten Haitzler (The Rasterman) * Add asin(), acos(), atan(), atan2(), log1p(), cbrt(), exp(), exp2(), hypot(), EMBRYO_12 define 2012-04-26 Carsten Haitzler (The Rasterman) 1.2.0 release 2012-06-14 Carsten Haitzler (The Rasterman) * Fix divide by 0 possibilities in the fp support so no FPE is produced (bad). 2012-08-30 Carsten Haitzler (The Rasterman) 1.7.0 release 2012-09-12 Carsten Haitzler (The Rasterman) * Fix windows utf/whitespace parsing issue in windows 2012-10-20 Cedric Bail 1.7.1 release 2012-11-23 Luis Felipe Strano Moraes 1.7.2 release 2012-12-07 Luis Felipe Strano Moraes * 1.7.3 release 2012-12-17 Vincent Torri * Add XML output to doc * Add installation rule for doc 2012-12-21 Luis Felipe Strano Moraes * 1.7.4 release 2013-01-04 Luis Felipe Strano Moraes * 1.7.5 release 2013-04-04 Rafael Antognolli * 1.7.6 release embryo-1.7.7/missing0000755000175000017500000002415212127360307011350 00000000000000#! /bin/sh # Common stub for a few missing GNU programs while installing. scriptversion=2012-01-06.13; # UTC # Copyright (C) 1996, 1997, 1999, 2000, 2002, 2003, 2004, 2005, 2006, # 2008, 2009, 2010, 2011, 2012 Free Software Foundation, Inc. # Originally 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.

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.

Documentation @image html e_big.png @version 1.7.5 @author Carsten Haitzler @author Compuphase http://www.compuphase.com @date 2004-2013 @section intro What is Embryo? Embryo is a tiny library designed to interpret limited Small programs compiled by the included compiler, @c embryo_cc. It is mostly a cleaned up and smaller version of the original Small abstract machine. The compiler is mostly untouched. Small was renamed to Pawn. For more information about the Pawn language, see @htmlonly Pawn @endhtmlonly @latexonly http://www.compuphase.com/pawn/pawn.htm @endlatexonly For the basics about the Small language, see @ref Small_Page. @section How_to_Use How to Use Embryo? To use Embryo in your code, you need to do at least the following: @li Include @ref Embryo.h. @li Load the Embryo program using one of the @ref Embryo_Program_Creation_Group. @li Set up the native calls with @ref embryo_program_native_call_add. @li Create a virtual machine with @ref embryo_program_vm_push. @li Then run the program with @ref embryo_program_run. @todo Clean up compiler code. @todo Proper overview of the operation of the interpreter, that is how the heap, stack, virtual machines, etc fit together. @page Small_Page Brief Introduction to Small This section describes the basics of Small, as compiled and interpreted with Embryo. This summary assumes that you are familar with C. For a full list of differences between C and Small, again, see the full documentation. @section Small_Variables_Section Variables @subsection Small_Type_Subsection Types There is only one type, known as the "cell", which can hold an integer. @subsection Small_Scope_Subsection Scope The scope and usage of a variable depends on its declaration. @li A local variable is normally declared with the @c new keyword. E.g. @code new variable @endcode @li A static function variable is defined within a function with the @c static keyword. @li A global static variable is one that is only available within the file it was declared in. Again, use the @c static keyword, but outside of any function. @li A stock variable is one that may not be compiled into a program if it is not used. It is declared using @c stock. @li A public variable is one that can be read by the host program using @ref embryo_program_variable_find. It is declared using @c public keyword. Remember that the keywords above are to be used on their own. That is, for example: @code public testvar @endcode not: @code new public testvar @endcode @subsection Small_Constants_Subsection Constants You can declare constants in two ways: @li Using the preprocessor macro @c \#define. @li By inserting @c const between the keyword and variable name of a variable declaration. For example, to declare the variable @c var1 constant, you type @code new const var1 = 2 @endcode Now @c var1 cannot be changed. @subsection Small_Arrays_Subsection Arrays To declare an array, append square brackets to the end of the variable name. The following examples show how to declare arrays. Note the use of the ellipsis operator, which bases the array based on the last two declared values: @code new msg[] = "A message." new ints[] = {1, 3, 4} new ints2[20] = {1, 3} // All other elements 0. new ints3[10] = {1, ... } // All elements = 1 new ints4[10] = {10, 20, ... } // Elements = 10 -> 100. // The difference can be negative. new ints5[3][3] = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}} @endcode @note Array initialisers need to be constant. @section Small_Func_Calls_Section Function Calls A typical function declaration is as follows: @code testfunc(param) { // Do something ... // over a couple of lines. } @endcode You can pass by reference. That is, the parameter you pass is changed outside of the function. For example: @code testfunc(¶m) { param = 10 // The passed variable will be set to 10 outside of the function. } @endcode To pass an array: @code testfunc(param[]) { // Do something to the array } @endcode @note Arrays are passed by reference. @section Small_Control_Subsection Control Structures. Small has the following control structures, which similar to their C counterparts: @li @code if (expression) statement1 else statement2 @endcode @li @code switch (expression) { case 0: statement1 // Can only be one statement. Look Ma, no breaks! case 1..3: // For values between 1 and 3 inclusive. statement2 default: // Optional statement3 } @endcode @li @code while(expression) statement @endcode @li @code do statement while (expression) @endcode @li @code for (init_expression; before_iter_test_expression; after_iter_expression) statement @endcode @section Small_Preprocessor_Section Preprocessor The following preprocessor directives are available: @li @code #assert constant_expression @endcode @li @code #define pattern replacement @endcode @li @code #define pattern(%1,%2,...) replacement @endcode @li @code #include filename @endcode @li @code #if constant_expression // Various bits of code #else // Other bits of code #endif @endcode @li @code #undef pattern @endcode @page Available_Native_Calls_Page Available Calls Embryo provides a minimal set of native calls that can be used within any Embryo script. Those calls are detailed here. @note Some of the "core" functions here are also described in the full Small documentation given @todo Finish this section. @section Args_ANC_Section Argument Functions @subsection Numargs_Desc numargs Returns the number of arguments passed to a function. Useful when dealing with variable argument lists. @subsection Getargs_Desc getarg(arg, index=0) Retrieves the argument number @c arg. If the argument is an array, use @c index to specify the index of the array to return. @subsection Setargs_Desc setargs(arg, index=0, value) Sets the argument number @c arg to the given @c arg. @c index specifies the index of @c arg to set if @c arg is an array. @section String_ANC_Section String Functions Functions that work on strings. @subsection Atoi_Desc atoi Translates an number in string form into an integer. @subsection Fnmatch_Desc fnmatch Buggered if I know what this does? @subsection Strcmp_Desc strcmp String comparing function. @section Float_ANC_Section Float Functions @subsection Float_Desc float @subsection Atof_Desc atof @subsection Float_Mul_Desc float_mul @subsection Float_Div_Desc float_div @subsection Float_Add_Desc float_add @subsection Float_Sub_Desc float_sub @subsection Fract_Desc fract @subsection Round_Desc round @subsection Float_Cmp_Desc float_cmp @subsection Sqrt_Desc sqrt @subsection Pow_Desc pow @subsection Log_Desc log @subsection Sin_Desc sin @subsection Cos_Desc cos @subsection Tan_Desc tan @subsection Abs_Desc abs Returns the absolute value of the given float. @section Time_ANC_Section Time Functions @subsection Seconds_Desc seconds() @subsection Date_Desc date @section Rand_ANC_Section Random Functions @subsection Rand_Desc rand() Returns a random integer. @subsection Randf_Desc randf() Returns a random float. @file Embryo.h @brief Embryo virtual machine library.

This file is free documentation; the Free Software Foundation gives unlimited permission to copy, distribute and modify it. Basic Installation ================== These are generic installation instructions. 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 only 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. If you're using `csh' on an old version of System V, you might need to type `sh ./configure' instead to prevent `csh' from trying to execute `configure' itself. Running `configure' takes awhile. 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. 4. Type `make install' to install the programs and any data files and documentation. 5. 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. 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=c89 CFLAGS=-O2 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 must use a version of `make' that supports the `VPATH' variable, such as 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 `..'. If you have to use a `make' that does not support the `VPATH' variable, you have 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. 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'. 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. 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'. Optional Features ================= 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. 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). Here is a another example: /bin/bash ./configure CONFIG_SHELL=/bin/bash Here the `CONFIG_SHELL=/bin/bash' operand causes subsequent configuration-related scripts to be executed by `/bin/bash'. `configure' Invocation ====================== `configure' recognizes the following options to control how it operates. `--help' `-h' Print a summary of the options to `configure', and exit. `--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. `configure' also accepts some other, not widely useful, options. Run `configure --help' for more details. embryo-1.7.7/AUTHORS0000664000175000017500000000013212127353614011016 00000000000000The Rasterman (Carsten Haitzler) Jérôme Pinot embryo-1.7.7/embryo.spec0000664000175000017500000000356612143517565012142 00000000000000%define _missing_doc_files_terminate_build 0 %{!?_rel:%{expand:%%global _rel 0.enl%{?dist}}} Summary: A small virtual machine engine (in a library) and bytecode compiler Name: embryo Version: 1.7.7 Release: %{_rel} License: BSD Group: System Environment/Libraries Source: %{name}-%{version}.tar.gz Packager: %{?_packager:%{_packager}}%{!?_packager:Michael Jennings } Vendor: %{?_vendorinfo:%{_vendorinfo}}%{!?_vendorinfo:The Enlightenment Project (http://www.enlightenment.org/)} Distribution: %{?_distribution:%{_distribution}}%{!?_distribution:%{_vendor}} URL: http://www.enlightenment.org/ BuildRoot: %{_tmppath}/%{name}-%{version}-root %description Embryo is a tiny library designed as a virtual machine to interpret a limited set of small compiled programs. %package devel Summary: Embryo headers, static libraries, documentation and test programs Group: System Environment/Libraries Requires: %{name} = %{version} %description devel Headers, static libraries, test programs and documentation for Embryo %package bin Summary: Embryo bytecode compiler and needed data files Group: System Environment/Libraries Requires: %{name} = %{version} %description bin The embryo bytecode compiler and its files %prep %setup -q %build %{configure} --prefix=%{_prefix} ### use this if you have build problems #./configure --prefix=%{_prefix} %{__make} %{?_smp_mflags} %{?mflags} %install %{__make} %{?mflags_install} DESTDIR=$RPM_BUILD_ROOT install %clean test "x$RPM_BUILD_ROOT" != "x/" && rm -rf $RPM_BUILD_ROOT %post /sbin/ldconfig %postun /sbin/ldconfig %files %defattr(-, root, root) %doc AUTHORS COPYING* README %{_libdir}/*.so.* %files bin %defattr(-, root, root) %attr(755,root,root) %{_bindir}/embryo_cc %{_datadir}/embryo/include %files devel %defattr(-, root, root) %{_libdir}/*.so %{_libdir}/*.la %{_libdir}/*.a %{_libdir}/pkgconfig/* %{_includedir}/embryo-1/*.h %changelog embryo-1.7.7/configure0000775000175000017500000170627012143517557011704 00000000000000#! /bin/sh # Guess values for system-dependent variables and create Makefiles. # Generated by GNU Autoconf 2.68 for embryo 1.7.7. # # Report bugs to . # # # Copyright (C) 1992, 1993, 1994, 1995, 1996, 1998, 1999, 2000, 2001, # 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010 Free Software # Foundation, Inc. # # # This configure script is free software; the Free Software Foundation # gives unlimited permission to copy, distribute and modify it. ## -------------------- ## ## M4sh Initialization. ## ## -------------------- ## # Be more Bourne compatible DUALCASE=1; export DUALCASE # for MKS sh if test -n "${ZSH_VERSION+set}" && (emulate sh) >/dev/null 2>&1; then : emulate sh NULLCMD=: # Pre-4.2 versions of Zsh do word splitting on ${1+"$@"}, which # is contrary to our usage.
