[GRASS-user] python commands on grass.

GRASS GRASS user

Dear all,

is there a way of I know the commands available on python grass library?

Checking the codes available at https://svn.osgeo.org/grass/grass/trunk/script
(thanks Martin) I saw the following commands:

grass.read_command
grass.parse_key_val
grass.run_command
grass.message
grass.fatal

By the way, how can I know the methods / parameters for each command?

Meanwhile, I can run g.list with the command bellow, but I can’t
deal with the name of each of my raster map. In fact I receive the
same output as in gis.m console, but I would like only receive a list of
maps as output.

rasterfiles = grass.read_command(‘g.list’,type=‘rast’)
Cheers

Hi,

is there a way of I know the commands available on python grass library?

grass.py is located in

lib/python

e.g.

https://svn.osgeo.org/grass/grass/trunk/lib/python/

It's best documentation :slight_smile:

rasterfiles = grass.read_command('g.list',type='rast')

use

grass.mlist_grouped(type = 'rast')

Try using help() from within the python shell.

python
import grass
help(grass)

and now there is even more (I have doxygenized the docs):

http://download.osgeo.org/grass/grass6_progman/
-> Further libraries
   -> python: GRASS 6 Python library

Improvements to the page are welcome, the file to edit is here:
