zig.vim VS coc-ccls

I'm not a fan of debuggers and whatnot, so I don't have anything for that, but I use zig.vim for Zig/C/C++/Obj. C/anything else integration like highlighting. Additionally, vim-scripts/a.vim can be used for alternating between implementation/header files. I don't use it myself but vim-snippets can be used for common snippets.

Out of the box Vim works well enough as an editor for Zig but the experience is a bit underwhelming. So I installed the Vim configuration for Zig plugin get syntax highlighting.

About the fast zig check, looking around the the zig.vim plugin code, I think it would be zig fmt --ast-check.

There is zig-vim, language server and support in nvim-treesitter

Currently there is no lua api for this command, so if you want a lua solution you would need to reimplement the functionality or reimplement the stuff inside this folder https://github.com/ziglang/zig.vim/tree/master/compiler

install zig for vim : https://github.com/ziglang/zig.vim

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?

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)
