pynvim VS deoplete.nvim

In a python remote plugin using pynvim, you could write something like this.

I can't fully recommend one example posted in #520 (because it has some practices that are not quite recommendable IMHO) but you may want to take a look at it.

To my knowledge no, but looks this is a common problem on Windows. Please file an issue on https://github.com/neovim/pynvim/ (a reproduction step would be greatly appreciated) so we can track it.

That should be it https://github.com/neovim/pynvim

You managed to pick two languages I don't use, but I believe it would more than meet your criteria. Neovim has excellent LSP support, and there are several for C/C++/CMake and for Python. See the list here. There's intellisense like completion via coc. For debugging there's also nvim-dap. With something like pynvim you could even write plugins for neovim itself in python. (I've written some in lua myself because of its native lua interface, which is a nice alternative to vimscript.)

pynvim doc is not very good IMO I will gladly use nvim --remote now that the feature is available if I ever need something from python!

As a sidenote, I didn't see another option besides making it as a python remote plugin, since I really needed to use Python's jupyterclient library (basically the Jupyter protocol is pretty complicated, and jupyter-client is its official implementation). And that sucks, because pynvim is badly documented and has a few really weird bugs (e.g. https://github.com/neovim/pynvim/issues/386), which I then had to work around.

Maybe this or this

I'm trying to use pynvim to write tests for a plugin (since I'm a big fan of pytest). However I cannot seem to configure the nvim session through a lua file. I've created an issue but thought I would also post here to see if someone knows what's going on since I haven't had a reply in a few days.

I think in-the-wild examples like Ultisnips deoplete semshi (although they are advanced and somewhat complex) would also be good examples to learn how one can use python for writing plugins.

If you post your issue on https://github.com/Shougo/deoplete.nvim/issues, Shougo might be able to better assist you.

I have a problem with Deoplete and Vim-LSP completion (Python's Pylsp and Jedi-Language-Server). The suggestion is much less, and it also misses a lot of opportunities to suggest compared to Deoplete-Jedi, which literally defeats the former by a large margin. Is there a setting to make this duo works like deoplete with deoplete-jedi?

Someone made an issue on this question, with the author suggesting float-previewnvim.

This exactly why I keep using deoplete! Other completion plugins don't handle middle of word completion correctly.

As we can see, it's a deoplete issue. By reading the docs at https://github.com/Shougo/deoplete.nvim, under the requirements section, it needs nvim to be compiled with python support.

Hmm. Maybe I don't know what to look for (not an expert at vim), but I have searched the deoplete documentation and I can't see any options to allow as-you-type omnicompletion. There are things like external sources, but I don't need that. Everything is available from , I just need that to be automatic.

For me I've been using deoplete.nvim for everyday use and for a long time and will probably transition to [ddc.vim](https://github.com/Shougo/ddc.vim] which is the next iteration after deoplete from the same author and is very similar to cmp in terms of setup with user customization.

To my knowledge thats not possible with omnicompletion. For this you would have to use an auto-completion plugin. I am using compe because its fast, minimal and integrates well with the builtin nvim-lsp but there are many others. The most popular is probably coc. You could also check out deoplete.
