YouCompleteMe VS coc-ccls

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 just did a fresh reinstall of CoC, on a newer version of Neovim. I'm now seeing something I hadn't seen before, which CoC calls "inlay hints". They look like this:

As recommended by michaelsbradley below, I installed https://github.com/nim-lang/langserver. I'm using coc.nvim (https://github.com/neoclide/coc.nvim) so I followed the instructions here from nim langserver https://github.com/nim-lang/langserver#vimneovim and seems to be working well!

Actually, I'm maintaining coc-perl (https://github.com/bmeneg/coc-perl), which enables the use of Perl LSP extension for vcode on vim/neovim using the CoC (https://github.com/neoclide/coc.nvim) backend. But it's completely on top of Perl::LanguageServer.

Plug 'https://github.com/neoclide/coc.nvim' " Auto Completion

I do think VSCode is a great tool and I recommend it frequently to people, but I still want to set the record straight here. Yes, vim is obviously limited in the sense that as a CLI app it doesn't draw it's own PDF or HTML windows, that's fair. But it can remote control your favorite PDF viewer or browser for roughly the same functionality. I'm currently writing my thesis using vimtex and it's quite smooth. And all the other stuff you mention is implemented quite competently by various plugins like vim-fugitive, coc.nvim, vimspector and copilot.vim.

Sounds like you want vim-which-key and coc.nvim.

Another option is to just download https://github.com/neoclide/coc.nvim Which is basically a one stop shop for completion, and it's pretty fast, it just uses nodejs instead of built in nvim lua functions.

coc.nvim

dont over copy and paste example .vimrc, keep it simple and grow tooling as you use. for linting and code completion : https://github.com/neoclide/coc.nvim (easy to add languages)
