Questions tagged [swig]

SWIG is an interface compiler that connects programs written in C and C++ with scripting languages such as Perl, Python, Ruby, and Tcl.

SWIG is typically used to parse C/C++ interfaces and generate the 'glue code' required for the target language 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.

For information about the features of SWIG and the supported languages see: http://www.swig.org/compare.html

One of many projects using SWIG to generate libraries for the above languages is Subversion. Other projects listed here.
