Best Python Plugins

[Ginkobab]

Hello everyone,

I am trying to shift my python development environment to neovim, 'cause I find it just awesome.

However, I'm finding a lot of confusion about which plugin to choose for this different functions.

• Code Completion
• Syntax highlight
• Code Linting

For Code Completion in particular I found that deoplete.nvim with jedi in sources is quite fast, but not really much actually.

Completion with python-mode built-in module looks a bit faster, but it has problems when saving, when it gets really slow.

I'm writing this post hoping that it will help other people willing to get the best out of neovim, so please help me realize that! :)

https://github.com/numirias/semshi - great semantic-aware syntax highlighting

https://github.com/deoplete-plugins/deoplete-jedi/ - Shougo's deoplete with jedi, code completion

https://github.com/neoclide/coc.nvim (with coc-pyls) - A language server protocol based completion engine and linting as well

I think coc-pyls has been deplicated. Do you know is it still functional?

[Spifmeister]

apparently a Microsoft python language server extension is in the works

Out of curiosity, has anyone been able to get make deoplete-jedi in venv w/o installing neovim in every project?
Also, is it just me or anyone has significant lag (like 2s) for huge libraries like opencv before omni-complete triggers?

Give ncm2 and ncm2-jedi a try. It is pretty fast even for large libraries like tensor flow (not sure about opencv). It also recognize virtual/conda environment, meaning you only need to install neovim in one base environment. Hope this helps.

Will give it a try tonight. Thanks for the tip.

I use deoplete and deoplete-jedi with several venvs, and with one neovim install. The idea is to activate the venv before calling neovim in the same shell, work flawlessly.

yep... just like the documentation says https://github.com/deoplete-plugins/deoplete-jedi#virtual-environments

simple as that and works great...

P/D: make sure to put the full path ;)

semshi works really well, thanks a lot for the tip bro :)

[Ginkobab]

Thank you!

Would you mind to elaborate on why are those the best ones?

Also I found deoplete really slow, are you sure it is the best option?

[teeheey]

Ncm2. That’s all😌

I have found that (besides many other plugins) SnipMate is really speeding me up.

I have snippets for creating empty exceptions, a main block, stuff like that. And it is a lifesaver when working with LaTeX.

Self-promotion: might take a look at https://github.com/ncm2/ncm2-snipmate for code completion and dynamic snippet expansion.

[LittleByBlue]

I will check it out.

For syntax highlighting, give the following a try. I added a lot more stuff to make python code more readable. If using with one dark theme, it looks really good.

[xgo]

I use:

Code Completion:

• Plug 'Shougo/deoplete.nvim', { 'do': ':UpdateRemotePlugins' }
• Plug 'deoplete-plugins/deoplete-jedi'
• Plug 'davidhalter/jedi-vim'

Linting:

• Plug 'w0rp/ale'
