[GRASS-user] g.parser options - values?

Hej,

I know how to use g.parser in a python script for
getting vector and raster maps like:

#%option
#% key: reliefmap
#% type: string
#% gisprompt: old,cell,raster
#% description: Name of shaded relief or aspect map
#% required : yes
#%end

but how can I use a value instead of a map, for example
a value that is parsed for the resolution-setting of
g.region?

Is there any good description of the settings of g.parser, e.g
what can be a type, what is exactly gispromt etc.?

Check for example r.neighbors, r.plane or even the g.region code.

An example from r.plane:

#%option
#% key: dip
#% type: double
#% gisprompt: -90-90
#% answer: 0.0
#% description: Dip of plane. Value must be between -90 and 90 degrees
#% required : yes
#%end

what can be a type, what is exactly gispromt etc.?

A starter is here:
