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.

I have written some C/C++ extension modules for PHP, using the 'old fashioned way' - i.e. by using the manual way (as described by Sarah Golemon in her book). This is too fiddly for me, and since I am lazy, and would like to automate as much as…

what does the last argument to SWIG_NewPointerObj mean?

I have a compatibility library that uses SWIG to access a C++ library. I would find it useful to be able to create a SWIG-wrapped Python object inside this layer (as opposed to accepting the C++ object as an argument or returning one). I.e. I want…

How does SWIG wrap a map in Python?

I'm using SWIG 2.0 to create a Python wrapper for a C++ library. One method has an argument of type "const std::map&". SWIG happily generates a wrapper for it, but I can't figure out how to invoke the method. If I pass, for example, {"a":"b"} for…
