deoplete.nvim VS completion-nvim

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.

I think it can be on any lua file. Plus I checked completion.nvim is now on archived.

You don't, nvim-cmp sets up you. Jokes aside, I am using completion-nvim. Unfortunately it got abandoned just as Neovim 0.5.1 got released, which contained a breaking change. You can look into the pending PRs to see how to fix it for yourself, just use one of the fixed forks. It really sucks, but unless someone steps up an creates a new completion plugin that's what I am stuck with.

I couldn't figure out how to change this. I found some options, some of which made an entire split window appear above... that's hideous. I also found this, but that works with lua. How do I even set up these lua scripts? I don't get it. Can I get some guidance? Thanks.

I have tried to move to nvim-cmp since completion-nvim is dead, but for the life of me I cannot figure out how to make it not automatically select the first completion candidate. If I type date and hit to insert a new line, cmp takes as the "confirm selection" key (because I have mapped it that way) and expands the snippet. I only want to confirm a selection if I actually selected something from the menu. completion-nvim may be dead, but at least its author had the courtesy to write down how to use it in complete plain English sentences instead of broken English one-liners. Eventually I gave up and moved back to the old setup.

That will give you the basics, you should see linter diagnostics and auto omin completion should work. For better auto-completion and snippets you can set up one of the completion- and snippets plugins. Personally I use completion-nvim and Ultisnips. There may be better plugins out there, that's just what I happen to have installed.

I recently upgraded from Neovim 0.5.0 to 0.5.1 and LSP autocompletion stopped working. I'm using https://github.com/nvim-lua/completion-nvim but it looks like its maintenance could be much better. I'm looking for some alternative but I'm not sure what would be a good choice for LSP. Any recommendations?

I'm trying to configure completion-nvim with Neovim's LSP, but am not getting any sort of pop-up/display.
