Add {rtp}/rplugin/python or python3 to jedi.settings.additional_dynamic_modules

Summary

I would like to enable completion on modules in rplugins.

Might help

What if there's a boolean option called deoplete#sources#jedi#vim_plugin_dev? Then $RUNTIMEPATH/rplugin can be added to sys.path.

FWIW: I've found that symlinking modules into ~/.vim/pythonx/ makes them available in Neovim/Vim, because of the special '_vim_path_' entry at the end of sys.path.
But this does not get picked up / used by the server probably?!

[tweekmonster]

@blueyed How does _vim_path_ work? I looked at the python client's source but it doesn't appear to do anything and I don't see anything in sys.path that relates to it.

In any case, I think the symlinking trick might be too obscure and not very portable.

Actually, instead of a variable maybe it would be better if rplugin/python{x,2,3} exists (cwd), just add the directories in &runtimepath to sys.path

[tweekmonster]

@lambdalisue Could you try the vim-dev branch? The paths should be added automatically if your cwd has a rplugin/python* directory.

@tweekmonster
It is handled through an import hook: https://github.com/neovim/python-client/blob/4dbfbd11a28b765a54928ebe6c6173c336ed841e/neovim/plugin/script_host.py#L228-L232 / https://github.com/neovim/python-client/blob/4dbfbd11a28b765a54928ebe6c6173c336ed841e/neovim/plugin/script_host.py#L237-L251.

But that is not used by the deoplete-jedi server.

But jedi-vim uses it, i.e. <Ctrl-x><Ctrl-o> (with omnifunc=jedi#completions) will use it for completions, but deoplete-jedi won't.

So, instead of manually adding rplugin, the same mechanism could/should be used in the server probably, which would make it behave like other clients/plugins?!

[tweekmonster]

WTF. When I was searching the code for VIM_SPECIAL_PATH it only jumped between the setup() and teardown() function! Maybe the code didn't load completely in my browser?

It looks like that script is only for the :python* commands, though. It could probably be used on the client side, but wouldn't work for the server since it would need to import from the neovim package. The venv users won't have that, and injecting the client's sys.path into the server wouldn't work for Python 2.

The code in the vim-dev branch essentially does the same thing anyways, albeit less elegantly.

Let's create a PR to discuss it?

I thought I created a PR 😱 I guess I commented instead.

Thanks!
