CDE/cde/contrib/desktop2dt/README

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

Hello,
I've been working on desktop2dt some more, and have a version that 
works much better.
It can handle icons in subdirectories, installing files (to $DESTDIR/etc/dt
or ~/.dt), and terminal applications.

There are still some missing features:
-line-wrapped entries 
-adding entries to the app manager
-file types and associations
 Unless we use libmagic, this will be a real pain.
-multiple locales ( for example, Comment[de]= could make an entry in the
 right locale).
 
Currently, it's hard-coded to output action databases in the C locale.


Usage is similar to the last version, except -i installs everything:
desktop2dt -i /usr/share/applications/nedit.desktop \
 /usr/share/applications/xephem.desktop
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

If you can test it, that will be a great help.  I've tried to stick to POSIX,
but I only tested on Squeeze.

Thanks,

Hello,

Here's the third revision of the script.

What's new:

* Converts %u, %U, %f, and %F to "%(File)Arg_1%" (with quotes).
* -a option to install in the app manager
(Thanks to Antonis Tsolomis for suggesting these improvements.)

* Slightly improved icon location search (based on PREFIX).

Still needs to handle wrapped lines, but that's the main issue with
processing .desktop files for applications that remains.

HTH,

Here's a fourth revison of desktop2dt.
Changes:
* export and test were changed for compatability with old shells like
 Solaris has
* ~ was changed to $HOME because it didn't always get expanded.

Not yet changed:
I'm inclined to prevent creation of appmanager folders more than 3 deep.

Still no multi-locale stuff. If someone has a way to figure out which
locales to grab (two-letter) and where they go (CDE locale), I'm open to
including it.

Still doesn't handle line wrap.  I may be able to deal with this.

The more platforms it's tested on, the better; I'd like to hear from
someone using one of the BSDs.

So far, it's been tested on Debian and Solaris, with at least the
following shells on Debian:
bash, dash, busybox ash, pdksh, mksh, ksh93
This would suggest that it should work on all the BSDs as well.

Besides POSIX sh, find, sed, and grep, it needs imagemagick (or
graphicksmagick + imagemagick-compat).

Thanks,
Isaac Dunham
