Port to gtkmm-3.0

[Daniel Landau]

Doing this would be in general useful as a future proofing measure, and as a specific example https://bugs.launchpad.net/referencer/+bug/116462 will be easier to solve with a newer GTK.

I started doing this myself, you can follow the progress at https://code.launchpad.net/~daniel-landau/referencer/gtk3

The porting effort has proceeded to the point where Referencer can be compiled and linked, but it segfaults and there are a number of other known issues (+ unknown ones) too. Now might be a good time to have a look at what I've done so far and give suggestions :)

With the latest change set at https://code.launchpad.net/~daniel-landau/referencer/gtk3 Referencer starts up successfully with gtkmm-3.0.

I know this is an old issue, but might get very important in close future. I think the efforts made in this branch could be very important to keep referencer alive once python2 reaches its end of life. As far as I understand the GTK3 update is required also in order be able to use referencer with python3.

Since this branch already has a running GTK3 version: Are there any plans to merge that back into master and fix eventual missing features?

I did some attempts to port to python3 on top of changes done in this branch. In case there is interest I can provide a patch.

[Daniel Landau (daniel-landau)]

I have a vague recollection that it wasn't fully functional with GTK3. I left i

[Daniel Landau (daniel-landau)]

Of, accidental post unfinished.

I left it unfinished as there was no indication that even a finished port would get merged.

Hi, I unfortunately do not use Referencer on a daily basis anymore, but I can still find some time to merge branches if they are stable and tried out by a few people.

[Mads Chr. Olesen (shiyee)]

Updating the other libraries, such as gconfmm would also be needed. This was the primary reason Referencer was removed from Debian: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=891699

[Dominik Kriegner (dominik-kriegner+lp)]

thats a pity...

I got the branch lp:~daniel-landau/referencer/gtk3 running (at least the base window of referencer). I think once python2 gets deprecated this might need to be revisited.
I upload attached a python3 patch which can be applied to the branch lp:~daniel-landau/referencer/gtk3

The patch includes some recent changes from trunk and the port to python3 of all plugins and plugin-system. mostly these are trivial changes. As mentioned by Daniel this does not yield a finished python3/gtk3 port, but somebody might start from this.
