Welcome to SWIG

SWIG is a software development tool that connects programs written in C and C++ with a variety of high-level programming languages. SWIG is used with different types of target languages including common scripting languages such as Perl, PHP, Python, Tcl and Ruby. The list of supported languages also includes non-scripting languages such as C#, Common Lisp (CLISP, Allegro CL, CFFI, UFFI), D, Go language, Java including Android, Lua, Modula-3, OCAML, Octave and R. Also several interpreted and compiled Scheme implementations (Guile, MzScheme/Racket, Chicken) are supported. SWIG is most commonly used to create high-level interpreted or compiled programming environments, user interfaces, and as a tool for testing and prototyping C/C++ software. SWIG is typically used to parse C/C++ interfaces and generate the 'glue code' required for the above target languages to call into the C/C++ code. SWIG can also export its parse tree in the form of XML and Lisp s-expressions. SWIG is free software and the code that SWIG generates is compatible with both commercial and non-commercial projects.

2011/05/21 - SWIG-2.0.4 released

SWIG-2.0.4 release summary:
- This is mainly a Python oriented release including support for Python
built-in types for superior performance with the new -builtin option.
The -builtin option is especially suitable for performance-critical
libraries and applications that call wrapped methods repeatedly.
See the python-specific chapter of the SWIG manual for more info.
- Python 3.2 support has also been added and various Python bugs have
been fixed.
- Octave 3.4 support has also been added.
- There are also the usual minor generic improvements, as well as bug
fixes and enhancements for D, Guile, Lua, Octave, Perl and Tcl.

- License changes, see LICENSE file and http://www.swig.org/legal.html .
- Much better nested class/struct support.
- Much improved template partial specialization and explicit specialization handling.
- Namespace support improved with the 'nspace' feature where namespaces can be automatically translated into Java packages or C# namespaces.
- Improved typemap and symbol table debugging.
- Numerous subtle typemap matching rule changes when using the default (SWIGTYPE) type. These now work much like C++ class template partial specialization matching.
- Other small enhancements for typemaps. Typemap fragments are also now official and documented.
- Warning and error display refinements.
- Wrapping of shared_ptr is improved and documented now.
- Numerous C++ unary scope operator (::) fixes.
