[GRASS-user] g.parser inside g.parser

[ivan marchesini]

Hi all,
We just created a script that creates another script.
I'll try to explain:


suppose we have a big text file (init.file) organized like that
_______________________________
parameter1	parameter2
0.3		0.9

parameter3	parameter4
1000		1

....		.....
_______________________________

but really more complex ....


we have just created a script (script1.sh) like this
(pseudocode)


____________________________________________________

#!/bin/bash
#%Module
#% description: description
#% keywords: blah
#%End
#%option
#% key: initfile
#% gisprompt: string
#% type: string
#% description: initfile
#% required : yes
#%end
if [ "$1" != "@ARGS_PARSED@" ] ; then
	exec g.parser "$0" "$@"
fi
- read the passed init.file
- parse the existing init.file and assign each parameter value to a
different variable
- echo "
	#!/bin/bash
	#%Module
	#% description: description
	#% keywords: raster
	#%End
	#%option
	#% key: param1
	#% gisprompt: string
	#% type: string
	#% description: DEM
	#% required : yes
	#% answer: first_variable_parsed_from_init.file
	#%end
	....

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

	./another_fortran_code param1=something param2=something .....
" > script2.sh
./script2.sh
_____________________________________________________


if we execute the script1 from command line

./script1.sh initfile=init.file

a new gui windows is opened from the execution of the script2.sh 


but when we simply run 

./script1.sh

the first gui window starts, we fill the form concerning the initfile
key, and then we click run, the second gui window (that produced by
script2.sh) doesn't start.

It seems a problem related to g.parser but we can't understand how to
solve it...

any help is really apreciated...

Thanks...

Ivan
