Python extensions for GRASS GIS

Python-SWIG-GRASS interface

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

Background: 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.

TODO: Implement modules support in a Python class using --interface-description and a Python-XML parser. This should be a generic class with module's name as parameter, returning back an object which describes the module (description, flags, parameters, status of not/required). See GRASS 6 wxPython interface for inspiration.

Python-GRASS add-ons
