vim-lsp-settings VS coc-ccls

I am reading here but still... it seems all OK. It is weird that it was working with ALE with the current setup. Anyway, I noticed that every once in a while I get this error when I change buffer.

There's https://github.com/mattn/vim-lsp-settings to save even more lines, which is I think what OP wants.

vim-lsp-settings makes installing lsp for vim-lsp trivial: :LspInstallServer

Hello everyone, I have this problem when using vim-lsp-settings, that every time my cursor passes through a word (sorry I don't have enough information to derive what type of word, but take Type, Function in Python, or constants (like g:lsp_diagnostics_signs_enabled) and has() in vimrc) it always showing similar occurrences of the word, and I don't want that. Not only it takes some time (highlighting that word cursor is on, and when moving cursor really fast it couldn't catch up), it's usually something I don't really need (well, if it could be configured to be faster and my laptop won't screeching then I'm all in - I'm using thinkPad x270).

I use vim-lsp plugin which only needs a few lines of config. It has several JavaScript language servers listed in vim-lsp-settings.

Then lsp. All four of these: prabirshrestha/vim-lsp; mattn/vim-lsp-settings; prabirshrestha/asyncomplete.vim; prabirshrestha/asyncomplete-lsp.vim

vim-lsp that can be bootstrapped with vim-lsp-settings, for jumping to definitions, etc.

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)
