Hello,
Earlier I noticed that *.dt files contain much the same information as
*.desktop files, so I thought I'd see about automatically converting
from *.desktop to *.dt.
Here's a first try, in the form of a shell script.
It reads one or more desktop files, listed on the command line,
to generate as many .dt files and the corresponding icons.
Each .dt file contains only the action that would start the command.
This does NOT handle quite a few things:
-multiple locales ( for example, Comment[de]= could make an entry in the
right locale).
-putting anything in the right place
-line-wrapped entries
-adding entries to the app manager
-file types and associations
-most sanity checks
That said, this works for me:
cd emptydir
desktop2dt /usr/share/applications/nedit.desktop \
/usr/share/applications/xephem.desktop
mv *.dt ~/.dt/types/
mv *.pm ~/.dt/icons/
touch ~/.dt/appmanager/Desktop_Apps/nedit
touch ~/.dt/appmanager/Desktop_Apps/xephem
chmod +x ~/.dt/appmanager/Desktop_Apps/nedit
chmod +x ~/.dt/appmanager/Desktop_Apps/xephem
and then go to Desktop_Tools > Reload Applications
I'd like to hear any comments you have.
Thanks,
Isaac Dunham
