GRASS and Python
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.
