[GRASS-dev] [grass-code patches][280] Fix Help button in gis.m raster/vector display conf locks up gis.m

[Michael Barton]

Maris,

When I try both "run" and "spawn" procedures for starting g.manual on my Mac
x11 GUI, both work fine without locking up anything. So I can't track why it
may be locking on yours (a few other people reported this issue, but it has
been variable in its persistence AFAICT). However, if I use spawn, it
generates the following message in the terminal every time the module help
button is pressed.

Starting browser <open> for module d.rast...

Other than a bit of clutter, this doesn't cause any other issues (but why do
we have this rather pointless message being sent to stderr?)

There was some recent discussion about help functionality/non-functionality
under windows and I remember something about the menu version of GRASS help
working, while the buttons in the options panels and module dialogs were
problematic sometimes.

This is the code for help in the menu. Maybe it would work better on all
systems (requires "global devnull" to be declared in the relevant
procedure).

exec g.manual -i d.rast > $devnull &

Does this work without lockup for you? Does it work for Windows...anyone?

Michael
