Bug 223279 – pygtksourceview does not depend on gnome, but only works if gnome is installed

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Rachel Greenham 2008-05-23 00:06:40 UTC]

Attempting to use a python-written application (pyroom) that makes use of pygtksourceview failed with an import error (No such module gtksourceview). Error also shows if you just try to import gtksourceview in a commandline python environment. Obviously, pygtksourceview itself is installed, but I was using xfce4 only.

Upon installing gnome (following a hunch based on other reported pygtksourceview issues, although those were old postings) it now works perfectly.

Reproducible: Always

Steps to Reproduce:
1. Install Gentoo base system (follow the handbook!) and get up to date.
2. emerge xorg-x11 and set up for use.
3. emerge xfce4
4. While logged into an xfce4 session, emerge pygtksourceview
5. $ python
>>> import gtksourceview
Error reported: No module gtksourceview found
6. emerge gnome (not necessary to log out and into a gnome session)
7. $ python
>>> import gtksourceview
>>>
(ie: success)

This was a very slow machine so it took days to confirm this test. I could attempt to do so again on a virtual machine in vmware (hosted on a faster machine).
Actual Results:  
gtksourceview module (before gnome is installed) could not be found by python.

btw: import gtksourceview2 doesn't return an error but also doesn't seem to result in objects that applications coded for it can use.

Expected Results:  
python module gtksourceview should be importable and usable when pygtksourceview is installed, but gnome isn't.

The version of pygtksourceview that *works* is the one brought in as part of dev-python/gnome-python-desktop. It installs /usr/lib/python${ver}/site-packages/gtk-2.0/gtksourceview.{la,so}.

Why is this distinct from the modules installed in dev-python/pygtksourceview? is that some completely different thing with the same name? Is it not possible to have a working gtksourceview for python that isn't dependent on bringing in large swathes of gnome?

[Comment 2 Gilles Dartiguelongue (RETIRED) 2008-05-24 14:41:15 UTC]

pygtksourceview provide bindings for gtksourceview-2 if your app doesn't work with this version then its deps are screwed. gnome-python-desktop will be splitted soonish but it'll take time if you want to see it land in stable.

[Comment 3 Gilles Dartiguelongue (RETIRED) 2008-05-24 14:41:37 UTC]

marking invalid because the app isn't actually in portage.
