[GRASS-dev] Re: wx init.sh needs updating

William,

I thought that the cvs version of init.sh was the one to use now. Please go
ahead and make the one further change. We should get rid of the init.sh in
the svn repository and instructions that say to use it. If you take care of
init.sh in the cvs, I'll take care of the svn version. Thanks for noticing
this.

I started messing around with a python replacement for init.sh, just to see
what is needed. It is going pretty well, but tedious. Once done (and
probably won't work right off) it could be a good opportunity to clean up
the start up script for GRASS. Thinking ahead to a time when the same script
can start GRASS on all platforms.

Just found some time to take a look at wxgrass again. The init.sh in
the svn gui source needs to be updated - there are a bunch of updates
missing, so if someone overwrites their existing init.sh per the
readme, the updates will be lost.

I see that most of the wx changes are already in the GRASS cvs
init.sh. The other option would be to update the readme install
instructions - with one update to the CVS init.sh, this step could be
removed. The one difference I found is the message about restarting/
starting the gui. This would take care of the different gui cases (I
left out d.m):

case "$GRASS_GUI" in
     tcltk | gis.m)
         echo "If required, restart the graphical user interface
with: gis.m"
         ;;
     wx)
         echo "If required, restart the graphical user interface
with: wxgrass &"
         ;;
     *)
         echo "Start the graphical user interface with: gis.m"
         ;;
esac

(I could apply that if you like.)

Theory of the Universe

There is a theory which states that if ever anyone discovers exactly
what the universe is for and why it is here, it will instantly
disappear and be replaced by something even more bizarrely
inexplicable. There is another theory which states that this has
already happened.

I also took care of the README and deleted the old init.sh from the SVN gui
folder.

Yeah, I just noticed a another oddity in init.sh related to wx - the gui dependency test is still based on X. While wxpython on other 'nix platforms may need X, it doesn't on OSX, and probably not on Windows either. Summarized:

if DISPLAY set (though it may be set but no X is available, at least on OSX)
   test gui dependency - python for wx, wish for tcltk
   if it fails
     warn that *wish* doesn't work (oops)
else
   no gui possible
   if a gui is set
     warn that *X* is not available, and there a gui is not possible (oops again)

Instead of testing the gui dependency first, maybe this should test the gui setting first:

case GRASS_GUI:
   tcltk, etc)
     test X availability
     or better, ignore DISPLAY and test only wish - if it works, X is implied, or whatever graphical base needed (this would take care of native tcltk implementations, like Aqua or Windows, not that they work well)
   wx)
     test python availability (X implied if needed - as long as python works)

...just some thoughts...

Sounds like this needs to be updated soon. I'm surprised that it doesn't
kick out an error for the native Windows version.

init.sh isn't used on native Windows - that's what init.bat is for. Unless you start GRASS from an Msys shell, when you could use init.sh and indeed it used to work - I haven't tested it recently though and we've been concentrating on getting Msys-independent WinGRASS working as well as possible.

This has been a very important effort. I'm teaching my graduate spatial
technologies class in the Spring and for the first time, I'll be able to use
GRASS as the primary software for this on all platforms.
