[GRASSGUI] python scripting support?

[Michael Barton]

What would it take to support python scripts like we support bash scripts.
That is, can we have a python script header that is automatically read and
parsed by menuform.py in some structured way to create a nice wxPython GUI
for ad hoc scripts? This could encourage people to start scripting
interesting things in Python, as well as porting existing scripts to Python.

g.parser can be used with any language which supports '#' as a comment
character. See general/g.parser/test.py for an example Python script
which uses g.parser.

The Python GUI can run such scripts with --interface-description to
get module/option/flag information in XML, from which a GUI could be
generated.

That's great. So it's already built in.

Any idea what would be the python equivalent of the bash lines...

if [ "$1" != "@ARGS_PARSED@" ] ; then
exec g.parser "$0" "$@"
fi

AFAICT:

if ( sys.argv[1] != "@ARGS_PARSED@" ):
os.execv("g.parser", [sys.argv[0]] + sys.argv)

[Michael Barton]

Thanks.

I'll play around and see if it works.

g.manual g.parser ;-)

The example given in the manual page is less than ideal, e.g. using
os.system() instead of os.execv(). This will fail if any of the
arguments contain spaces or other shell metacharacters.

thanks, glynn, I'll try to update
