#3475 new defect

r.mapcalc expression does not accept fully qualified map name as an output

Reported by: marisn Owned by: grass-dev@…
Priority: minor Milestone: 7.6.2
Component: Raster Version: svn-trunk
Keywords: r.mapcalc Cc:
CPU: Unspecified Platform: Unspecified


All raster and vector modules should accept fully qualified map name as an output parameter and ignore @mapset part as long as mapset == current mapset. This is implemented in Vect_open_new() and G_open_raster_new(). Still r.mapcalc is failing with an error:

mapcalc> sample@mapset=1
syntax error, unexpected '@', expecting '('

See extra discussion at bug #676 I'll try to fix r.grow code to strip @mapset part as a workaround as at the moment it fails to overwrite an existing map when called from WXGUI.

Is there any activity on this? I have the following pending for a recently published add-on:

Reading Glynn's last comment, do I understand correctly that I should take care to strip '@mapset' part at the add-on/module level?
