Add a .desktop file

[FSMaxB]

It would be great to add a .desktop file by default when installing the GUI version. Look here for an example.

This would also require installing an icon to /usr/share/pixmaps. Preferably U.svg.

Happy to consider a PR.

I don't understand how make install works for unison to be honest. Usually there is DESTDIR that can be set for installation directory. But unison doesn't seem to do that. It uses "$(HOME)" instead.

Maybe that should be fixed first. (DESTDIR could be set to $(HOME) by default to preserve the existing behavior.

I don't think that many people use "make install," other than me. :-|

Your proposed refinement sounds good.

[FSMaxB]

Actually I gave up for now. This is more complicated than I expected.

It would be easier if:

• unison would build executables with different names for different UISTYLE. e.g. unison-text unison-gtk2
• there was a way to know what has been built when running make install, which could just be the filenames from the build step
• unison wouldn't try to build the code again when running make install

[bcpierce00]

These also seem like reasonable refinements. One could retain backward compatibility by copying the latest-built binary (unison-text or whatever) to 'unison'.

The reason we never did something like this is that there are actually just three UI configurations (text, GTK, and the OSX native one); of these, the build and install procedure for the third is separate from the other two, while the GTK configuration supersedes the text one (i.e., it can be used in both ways).

The one from Debian is better IMHO, it properly utilizes GenericName, although needs version string removed or scripted:

[Desktop Entry]
Name=Unison
Comment=GTK interface for the unison file synchronization tool 2.48.4
GenericName=File synchronization tool
Exec=unison-2.48.4-gtk
Terminal=false
X-MultipleArgs=false
