Glynn,
Thanks much for responding so quickly. Here is what happens. If you just want to echo a string, it works OK. If you want to use the string as an argument to an option, it won't work. For example, look at d.vect. In the SQL box, you can put <field>=value and it works fine (no spaces). But you cannot put <field>=value and <field2>=value2. This generates an error that <field> value <field2> and value2 are illegal values--i.e., it treats each part of the argument as a separate entry. However you can do this on the command line with sql='<field>=value and <field2>=value2'.
I ran into this trying to do a script for gdalwarp. I just hit it again doing a script to make v.in.ascii read in a points file from a GUI interface. To specify column definitions you need to do
v.in.ascii .... columns='xcoord double,ycoord double,name varchar(10)' or something along that line.
This works from the command line. But in a g.parser GUI dialog, anything you put into am entry box for this variable gets parsed as a series of illegal entries rather than a single string argument. I've tried to quote it in the script, manually when I enter it, and other ways and have the same results.
Michael

grass binary for platform: MacOSX
GRASS Version: 5.7 26-03-2004g.parser has difficulties parsing strings with spaces in them. If you
enter a string with spaces, it treats each word as a separate, illegal
entry for that variable.I can't reproduce this behaviour with 5.3, and g.parser itself is
unchanged in 5.7 (although G_parser() has some changes).Are you sure that the problem isn't in the way that the GIS_OPT_*
variables are used in the script? Have you tried it with the test.sh
script from the g.parser directory? E.g.$ test.sh rast=fields vect=fields option1='hello world'
Flag -f not set
Value of GIS_OPT_option1: 'hello world'
Value of GIS_OPT_raster: 'fields'
Value of GIS_OPT_vect: 'fields'--
