vim-lsp VS coc-ccls

Has anybody managed or got an idea how to make SonarLint Language Server work with e.g. vim-lsp?

You need to configure a language server. For C++ it's a bit tricky, so good luck with Go. There are other plugins that provide semantic highlighting using LSP, for example https://github.com/prabirshrestha/vim-lsp (I didn't try it, but it seems good).

ALE can use LSP as well. And if you are using vim-lsp, you can use the same instance of server for both with vim-lsp-ale bridge plugin.

I feel the same way. Not a one-liner but the smallest config LSP plugin I've found is vim-lsp. It works in both Vim and Neovim.

The only major feature that Neovim still has is a built in LSP client. But I find the built in Neovim LSP client is unusably buggy, you're much better off using any of the other LSP plugins. What I use is vim-lsp, but I've tried all of the major lsp client, they are all significantly better than the built in Neovim LSP.

As for install/configuration, all you need is the latest Vim, the plugins I mentioned, and that bit in your vimrc. You can do a bit better than that if you copy the entire config with mappings from the vim-lsp GitHub page.

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?

- add the [prabirshrestha/vim-lsp](https://github.com/prabirshrestha/vim-lsp) plugin and config to your `.vimrc` (note: `pylsp` is *not* necessary).

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.

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?

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)
