YouCompleteMe VS completion-nvim

For vim specifically, I've been using coc.nvim, which works pretty well for my needs, and I know its quite popular. Another fairly popular one is YouCompleteMe, which I had taken a look at for some other languages; but ended up just using coc as I can't justify using YCM once a year (if that) -- too much "headache" for not a lot of use, you know?

YouCompleteMe. A pretty good autocompletion plugin, though vim does have its own, somewhat useful built-in auto completion that requires more keystrokes

There are plugins to do semantic highlighting. I don't use any of them because I'm satisfied with Vim's native syntax highlighting and with tree-sitter (and also because I don't use LSPs), but searching for "Vim semantic highlighting" on DuckDuckGo yields this: https://github.com/ycm-core/YouCompleteMe. The highlighting used in its demo is too baroque for my taste, but looking at your VSCode screenshot, it looks like it would be right up your alley.

The plugin that is requiring Python3 is You Complete Me here is the link!! The Vundle link I was looking at is also in the body of my post.

I use vim for C++ coding, however it is a bit difficult to set up to make it productive. I use YouCompleteMe [0] for autocompletion, Vimspector [1] with the C++ plugin for debugging, ALE [2] for linting, along with a few other general plugins (such as NerdTREE for file view).

I didn't make a complete list of requirements :) This issue makes YCM uninteresting to me, so I've not dug too deep into it.

my favorite is YouCompleteMe.

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.
