Errors in normal neovim using dein since installing oni

[topaxi]

Since I've installed oni I get these errors in my console neovim:

Any way to get rid of these? Does oni install plugins into my neovim plugin dir?

[bryphe]

That's strange, Oni does not install plugins into your neovim plugin dir.

A few questions:

• What platform are you on?
• What does :set rtp? return in Neovim?
• What Neovim plugins do you have installed?

When Oni creates a Neovim instance, it adds Oni's plugin folders to the runtimepath, but that should only impact the session running in Oni - unless you have a plugin that happens to cache or store the runtimepath.

I'm on Ubuntu Linux 17.10

:set rtp?

I'm using dein for plugin management:

Thanks for the info, @topaxi ! Sorry that you hit this.

It seems like an integration issue with dein... It looks like dein does this thing where it saves the runtimepath: https://github.com/Shougo/dein.vim/blob/09db90d2073c0c921c4e4046fffba343009da898/autoload/dein/util.vim#L267

I imagine what happened is that Oni ran with dein, and then dein saved the runtimepath (along with the ones Oni adds).

It looks like dein exposes a call to clear that cache via :call dein#clear_state() to revert that, but I don't know a ton about the side effects. You could also try modifying the cached vim file that dein creates directly and remove those.

I started modifying the Wiki to call out issues like this - adding an 'Incompatible Vim Plugins': https://github.com/onivim/oni/wiki/Plugins#incompatible-vim-plugins

[topaxi]

Awesome, thanks for debugging this :heart: I've disabled dein#save_state() in oni now using:

if !exists("g:gui_oni")
  call dein#save_state()
endif

I've also added this snippet to the wiki page.

According to @Shougo in https://github.com/Shougo/dein.vim/issues/262, if the behavior oni runs nvim is changed to --headless instead of --embed, the issue could be fixed. Is there any chance of fixing this issue?

[bryphe]

@brglng - thanks for the heads up. I'll reopen this.

I'm not familiar with the difference between --headless vs --embed - does --headless still enable extended UI functionality?

[Shougo]

if the behavior oni runs nvim is changed to --headless instead of --embed, the issue could be fixed. Is there any chance of fixing this issue?

No. I will implement runtimepath checking in dein.vim.

[bryphe]

Thanks @Shougo ! Let me know if there is anything I can do on the Oni side

[Shougo]

I have fixed the problem in dein.vim.

[badosu]

Thanks @Shougo!

@topaxi Let us know if you still find any issues after the last dein.vim changes.
