mason.nvim VS coc.nvim

I recently started coding with Neovim using kickstart.nvim as the template for my editor configuration. I downloaded the python-lsp-server package using Mason, but I was disappointed to discover that the IntelliSense on my third party dependencies didn't work. The LSP was resolving to my global Python installation, which did not have the packages from my virtual environment (venv) installed.

https://github.com/hrsh7th/nvim-cmp This is an autocompletion engine https://github.com/nvim-treesitter/nvim-treesitter This allows NeoVim to install parsing scripts so NeoVim can do things like code highlighting. https://github.com/williamboman/mason.nvim Not strictly necessary, but allows you to access a repo of LSP, install them, and configure them for without you actively messing about in config files. https://github.com/neovim/nvim-lspconfig Also not strictly necessary, but vastly simplifies LSP setup. https://github.com/williamboman/mason-lspconfig.nvim This lets the above two plugins talk to each other more easily.

I'm using mason.nvim to install my dependencies, I've this snippet at nvim/plugin/mason.lua so after cloning my dotfiles I can just run:

The suggestion from this thread fixed it for me. I just needed to unset GOOS and GOARCH then restart neovim.

For instance, I'm trying to install rust-analyzer in lazyvim from https://github.com/williamboman/mason.nvim. The installation instructions are:

I have pyright installed via mason which apparently support "semantic token highlighting" but have been having a hard time getting these colors to show up in a buffer. It seems Neovim has changed how it handles semantic highlighting a few times so there's still some conflicting information online. It's hard to know what's current and what's not. Any help would be greatly appreciated.

Use mason to install the language servers you want.

Because null-ls.nvim & mason.nvim together do everything I wanted CoC for

As well as its own plugins Vim/NeoVim can use VSCode's LSPs, DAPs and extensions either directly or via plugins like CoC[1] and Mason[2].

I would be surprised if emacs couldn't do the same.

The most famous TypeScript one probably is coc.nvim

It is flatly the wrong mindset to think of vim as an IDE. vim is a code editor: get in, make change, get out. Consider vim koans, which are a fun little read. You can throw coc.nvim at Neovim, along with a few other bits to give you a Good Enough setup, but vim isn't and will never be an IDE.

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:

I'm currently on an old setup (using coc and polyglot) and nvim v0.6.1. I'll be updating to a more modern setup within next year, using the native lsp and building nvim more frequently. But that's not today.

coc.nvim

There are some plugins which have the best documentations I have ever seen, but you need to read it from the Vim.

Example of coc.nvim: https://github.com/neoclide/coc.nvim/blob/master/doc/coc.txt

Actually you can with coc.nvim & coc-sh. So long as shellcheck is also installed and in PATH, it'll integrate with coc/vim just fine.

When you install an extension it runs an npm install or yarn, iirc, which is going to be problematic for you being offline. I was going to say you could copy that ~/.config/coc folder directly to the other machine but yeah, Windows, no idea. You see here https://github.com/neoclide/coc.nvim/wiki/Using-coc-extensions

You can try https://github.com/neoclide/coc.nvim, the pre-requisite is to install nodeJS, then to install all the languages LSP. This works for me for Angular, Rust, JavaScript, Vimscript, etc
