[GRASS-dev] G70 annoing error during the command parsing

[Pietro]

Hi all!

I'm trying to write a grass7 add-ons, but I'm fighting with one
parameter that wont work... and I'm not able to understand where the
problem is...

the python code is:

{{{
#!/usr/bin/env python
# -- coding: utf-8 --
#%Module
#%  description: Test
#%  keywords: test
#%  keywords: options
#%  overwrite: yes
#%End
#%option
#%  key: hdf
#%  type: string
#%  description: Name of the HDF file
#%  required: yes
#%end
#%option
#%  key: ychk
#%  type: string
#%  description: Name for the training values in the HDF
#%  required: no
#%end
#%option
#%  key: Kchk
#%  type: string
#%  description: Name for the training values in the HDF
#%  required: no
#%end
from grass.script import parser


def main(opts, flgs):
    for k, v in opts.items():
        print "%s = %r" % (k, v)


if __name__ == "__main__":
    options, flags = parser()
    main(options, flags)
}}}

the Makefile is:

{{{
MODULE_TOPDIR = ../..
PGM=r.try
include $(MODULE_TOPDIR)/include/Make/Script.make
default: script
}}}

The script is working If I don't use the Kchk parameter:

{{{
> r.try hdf=result.hdf ychk=y_chk
hdf = 'result.hdf'
Kchk = ''
ychk = 'y_chk'
}}}

otherwise it raise an error:

{{{
> r.try hdf=result.hdf ychk=y_chk Kchk=K_chk

Description:
 Test

Keywords:
 test, options

Usage:
 r.try hdf=string [ychk=string] [Kchk=string] [--overwrite]
   [--verbose] [--quiet]

Flags:
 --o   Allow output files to overwrite existing files
 --v   Verbose module output
 --q   Quiet module output

Parameters:
   hdf   Name of the HDF file
  ychk   Name for the training values in the HDF
  Kchk   Name for the training values in the HDF

ERROR: Sorry <Kchk=K_chk> is not a valid option
}}}

Do you understand what I'm doing wrong? why is ychk working?
I'm using grass r57429

Best regards.
