Modified jedi version to autocomplete Gtk

[albfan]

This is just a quick implementation to allow vim to autocomplete GObject introspection

But adding import gi to pythonx code for this plugin, leads to:

"meld/filediff.py" 2020L, 84352C
Please install Jedi if you want to use jedi-vim.
The error was: /usr/lib/python3.6/site-packages/gi/_gi.cpython-36m-x86_64-linux-gnu.so: undefined symbol: PyUnicode_FromFormat

Maybe I can fix this with pythonthreedll I'm really not sure

If it helps, here is JediDebugInfo

This is definitely not happening. If you want jedi-vim to work properly with jedi, get the commits merged in Jedi.

[albfan]

About 0.12 you mean, or what?

[davidhalter]

Look, you're trying to change ownership of Jedi to you. The only way this makes sense is if you are going to maintain Jedi for the next few years. But I doubt that and therefore you should probably just try to work on a pull request in Jedi itself.

[albfan]

Oh no, just sending a PR which needs to tweak jedi, so I change that in a fork and link to it.

How am I supposed to show you the problem vim has with a jedi-vim plugin that uses a jedi implementation which dinamically loads GObject introspection?

[davidhalter]

Look, you can do everything with stuff like jedi.Script('import x; x.').completions(). That is also way easier for me to reproduce. Your problem is not with jedi-vim. It has nothing to do with that.

[albfan]

Ok I will ask on vim for that error.

The final purpose of this PR is to get progress on davidhalter/jedi#531 so jedi-vim autocompletes on gi.repository without do anything
