Oni: Can't use Oni b/c of Python in non-standard path

[daenney]

I've just loaded Oni and I wanted to edit the settings but I can't. I get flooded with the messages from the screenshot on every interaction I try, essentially putting Oni in gridlock.

The reason this seems to happen is b/c Oni needs Python but my Pythons are in a non-standard place because I maintain a separate virtual env for my editor Python. In neovim I account for that by setting g:python_host_prog and g:python3_host_prog to the right locations, but that setting isn't exposed by Oni. Though I can make Oni read my .config/nvim/init.vim that'll probably break a lot more due to the amount of customisation in there.

Since Oni appears to require Python to function I think those options should be configurable (and the absence of it handled slightly more elegantly). Alternatively, Python could be bundled?

Hi @daenney ,

Thanks for posting the issue! Ya, that does not look very usable 😦

Just curious - what platform and neovim version are you using? Oni actually shouldn't require Python to run. I'm wondering what the output of --version is.

Being able to specify g:python_host_prog and g:python3_host_prog from the Oni config is a good suggestion - that could at least help mitigate this issue.

If Oni doesn't require Python, any idea why this shows up?

Interesting... I just tried Oni on my Mac (Sierra 10.12.5), and ran :CheckHealth to make sure I wasn't loading python, and I don't have a python provider registered. It _is_ able to find Python 2.7, though (just not the module).

As a temporary measure, to check if this is the issue, could you please try setting g:python_host_prog in /Contents/Resources/app/vim/default/bundle/oni-vim-defaults/plugin/init.vim? This is the file that has an initial init.vim for Oni. This will just help validate that this is the root cause (and hopefully allow you to try Oni).

[daenney]

Making the change you suggested to init.vim fixes it, so it does seem that it needs to at least be able to find a Python executable.

Thanks for making that tweak and confirming, @daenney ! I'll leave this open to track adding the g:python_host_prog and g:python3_host_prog variables as configuration settings in Oni.

It'd be nice to have a general solution for this, like:

"neovim.global.python_host_prog": "~/non-standard-python-path",

(Basically, have a way to assign any global configuration values directly in the Oni config). This is touched on some in #33 too

[daenney]

That would be awesome. Thanks for looking into it. In the mean time, I can now try Oni 😀
