[GRASS5] Re: [bug #2488] (grass) Transaction (glynn.clements@virgin.net)

[Michael Barton]

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.
