[GRASS-user] Python scripting: Proper use of run_command / start_command

["Peter Löwe"]

Hi all,

I am struggling with the proper use of start_command/run_command for Python scripting.

The programmers manual provides this simple example:  
p = grass.start_command("g.gisenv", stdout = subprocess.PIPE) 

What is the proper way to include keyword-arguments tuples ?

For example, "g.list -f type=rast,vect" should translate into something like:

grass.run_command("g.list","f",dict(type="rast,vect"))
^- this invocation of the run_command fails: 

ERROR: Required parameter <type> not set:
        (Data type)

Any advice on how to get this right would be much appreciated.

Peter
