ddc.vim VS completion-nvim

Have a look at ddc.vim and denops.vim

There is shougo/ddc.vim by the same author

e.g:https://github.com/Shougo/ddc.vim

I use dense-analysis/Ale for code linting. Lately, I moved to update my tab completion from deoplete to Shougo/ddc.vim; the autocompletion of Ale is routed to ddc using statiolake/ddc-ale but the Ale autocomplete leaves things to be desired.

I was looking at ddc.vim and it looked somewhat similar to nvim-cmp. There's also multiple sources for it with no inbuilt ones. So, I was wondering if anyone has used both of them and could provide some pointers on a rough comparison between the both. Also, if there's any config file with sources for lsp, buffer, and other useful ones already setup, then could you share that too?

Sadly deoplete doesn't play well with 'some' asynchronous plugin sources (ex: vim-iced). I still got to try ddc.vim to see if things are easier and if middle word completion is done right.

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.
