GRASS and Python

Python extensions from GRASS GIS

There is a prototype GRASS-SWIG interface available (thanks to Sajith VK), find in GRASS 6-CVS: swig/python/

SWIG (Simplified Wrapper and Interface Generator) is:

• A compiler that turns ANSI C/C++ declarations into scripting language interfaces.
• Completely automated (produces a fully working Python extension module).
• Language neutral. SWIG can also target Tcl, Perl, Guile, MATLAB, etc...
• Attempts to eliminate the tedium of writing extension modules.
