Hi Jose.
I changed the code by trying different solutions, such as:
------------------------------------------------------------------------------------------
def main():
vect1 = options['vect_1']
vect2 = options['vect_2']
vect3 = options['vect_3']
vbuffer=subprocess.Popen('v.buffer','input=vect_1','output=buffer_200m','buffer=200')
retcode=vbuffer.wait()
# Then I also tried with another command (v.db.addcol):
#import subprocess
#vaddcol=subprocess.Popen('v.db.addcol','map=vect_1','columns=prova','VARCHAR(15)')
The parameter for v.db.addcol is columns='prova varchar(15)'. I don't
think you can split that up into two parameters. Shouldn't this be:
vaddcol=subprocess.Popen('v.db.addcol','map=vect_1','columns=prova
VARCHAR(15)')
?
(don't know if the white space is allowed as such or whether you need to
quote the entire parameter as "prova VARCHAR(15)")

Yes, I have tried in this way but not right (with 'columns=prova
VARCHAR(15)').
Now I have also tried to remove white space but ... nothing
As Glynn has already said: check the existing scripts in trunk[1]. E.g.
in v.rast.stats.py:
if i == "n":
coltype = "INTEGER"
else:
coltype = "DOUBLE PRECISION"
addcols.append(currcolumn + ' ' + coltype)
if addcols:
grass.verbose("Adding columns <%s>" % addcols)
if grass.run_command('v.db.addcol', map = vector, columns =
addcols) != 0:
