#436: access to python swig bindingsa from outside of a grass session
-----------------------------------+----------------------------------------
Reporter: mulligan | Owner: grass-dev@lists.osgeo.org
     Type: enhancement | Status: new
Priority: major | Milestone: 6.4.0
Component: Python | Version: svn-develbranch6
Keywords: python, SWIG, session | Platform: Linux
      Cpu: x86-32 |
-----------------------------------+----------------------------------------
The SWIG bindings to Python are very useful from inside GRASS but would be
much more powerful if python could access GRASS functions from outside a
grass session.

I note the following in the TODO file at
http://svn.osgeo.org/grass/grass/branches/develbranch_6/swig/python/TODO:
""
- enable calls from outside GRASS
""
If this is now possible (in 6.4.0 or 7.0.0) could a relevant example be
posted to show how we can access from outside a grass session?

Many thanks

Mark

Comment (by hamish):

you just need some environment variables set to mimic a grass session.

see http://grass.osgeo.org/wiki/GRASS_and_Shell

SWIG support is removed, try ctypes in devel versions of GRASS instead.
