mason.nvim VS neoformat

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

I see that AstroNvim uses null-ls.nvim to format files. That does not format Markdown tables, so I added use of the Neoformat plugin to do that. But there is a major issue that I described here: https://github.com/sbdchd/neoformat/issues/457.

hi, this is perfect!!! Thanks for recommending. here is a link for anyone curious: https://github.com/sbdchd/neoformat

You could use Neoformat, and manually run :NeoFormat! pgFormater on a visual selection or create an autocmd to do the same automatically on save.

I like https://github.com/sbdchd/neoformat for that usecase. I was able to simplify my init.lua a lot by switching from null-ls.

Pick your poison (in no particular order): - au BufWritePre *.py %!isort -d - - https://github.com/sbdchd/neoformat - https://github.com/mhartington/formatter.nvim - https://github.com/jose-elias-alvarez/null-ls.nvim - ...

For me, neoformat is the best 👍

NeoFormat

There are plenty of code-formatting plugins, like auto-format and neoformat, for vim. But all of them require running a certain command or using :w to trigger formating.

You can use it with neoformat, they have instructions in the README to set up formatting on save. Which is what you want. Or you could create an autocommand/mapping to run shfmt on the current buffer without having to install a plugin.

Formatting - I just use prettier with neoformat. For indent size, I just do setlocal tabstop=2 shiftwidth=2 softtabstop=2 within ftplugin/javascriptreact.vim (and others - probably a better way to do this but it works).
