I’m trying to test error trapping code for the GRASS startup that will gracefully deal with invalid .grassrc6 settings for gisdbase, location, or mapset.<BR>
<BR>
When I try to test this (i.e., with a bad setting), I get a shell error before I even hit the gis_set.tcl file.<BR>
<BR>
ERROR: LOCATION << /Users/Shared/grassdata/nothing >> not available<BR>
/Users/Shared/grassdata/nothing/PERMANENT/.gislock: No such file or directory<BR>
ERROR: /Applications/Grass/GRASS-6.3.app/Contents/Resources/etc/lock:<BR>
cmbarton is currently running GRASS in selected mapset (file /Users/Shared/grassdata/nothing/PERMANENT/.gislock found). Concurrent use not allowed.<BR>
logout<BR>
<BR>
I can find this the code for this in init.sh and am wondering if it is in the script that launches the Mac app? I need to disable it to test the TclTk (and wxPython) code. If not Mac specific, can someone tell me where this code is?<BR>
<BR>
Rather than simply raising an error, which would be meaningless to someone who doesn’t know what a .grassrc6 file is, it would be better if an invalid setting branched the GRASS startup to the prompt that comes up when gisdbase, location, or mapset is not set—allowing a user to choose a valid value.<BR>
