Hi Michael, Markus, ...,
that's true, '--q/--v' should not influence format for listing in this
way! I added parameter 'ncols' for "Number of elements per line". But
the verbose listing still uses G_list_elements(), so 'ncols' doesn't
work together with '-f' flag.
Path attached.
For scripting
$ g.list rast ncols=1 --q
$ g.list help
Description:
Lists available GRASS data base files of the user-specified data type
to standard output.
Keywords:
general, map management
Usage:
g.list [-f] type=datatype[,datatype,...] [mapset=string] [ncols=value]
[--verbose] [--quiet]
Flags:
-f Verbose listing (also list map titles)
Prints one element per line
--v Verbose module output
--q Quiet module output
Parameters:
type Data type
options: rast,rast3d,vect,oldvect,asciivect,icon,labels,sites,
region,region3d,group,3dview
mapset Mapset to list (default: current search path)
ncols Number of elements per line (0 for autodetect)
default: 0

Thanks very much Martin. Not knowing C, I'm not exactly sure what to do with
this, but will try to work with it if no one else gets to it first. I'm not
sure I'd hang the different format on the --q flag. Maybe a -l (for
listing?) flag would be better.
Once this is worked out and in the cvs, I'll put it into select.py. I don't
know if you've had a chance to look, but I added a class to allow select to
be called in a separate dialog and a method that lets you update the element
list after you've created a selection control.
