tree-sitter-rust VS nvim-treesitter

Yes. It's typically a fair bit slower than a hand-coded parser. The idea sounds great until you're working on a codebase with 2 million LOC. At that point, the speed of a cold parse is most important, whereas TS is designed for fast re-parsing of a single file. These aren't great numbers but the Rust TS parser is reportedly 2x slower than rustc's https://github.com/tree-sitter/tree-sitter-rust. It's no surprise that you just use the faster option if it's convenient.

Notes for anyone interested, there is this PR https://github.com/tree-sitter/tree-sitter-rust/pull/128, which merges successive doc comments.

Tree-sitter is a fantastic parser generation and incremental parsing library, that supports Rust language bindings and has an available parser Rust tree-sitter-rust.

You can see a much more in-depth version at https://github.com/tree-sitter/tree-sitter-typescript or https://github.com/tree-sitter/tree-sitter-rust

I'll be really interested to see what folks end up preferring once nvim 0.5 ships with treesitter support. Do folks have any experience with the Rust grammar?

Neovim could use the default regex based grammar that Vim uses for syntax highlighting. But I recommended installing treesitter. This uses a concrete syntax tree to provide more semantic meaning to tokens, allowing enriched (and faster) highlighting.

👉 Tree-sitter plugin for code highlighting.

Treesitter is what makes your neovim colorful. It uses the LSP and colorscheme and colors your variables, keywords and other stuff. To understand how treesitter works and configure treesitter please read the docs. Here is my configuration for treesitter:

nvim-treesitter is a plugin that has been around for 4 years now. A lot of people will say this is essential to your Neovim experience, and I do agree to some extend. It is incredibly useful... as a dependency for other plugins. It allows Neovim to gather more information about source code of the current file, and plugin authors can do really cool things that. For "normal users" like you and me there are some modules we can enable. One of them can be used to enhance the syntax highlight of many programming languages. That I think the feature nvim-treesitter is known for.

I wouldn't really count those. Every editor with treesitter support will have those, it's for treesitter: https://github.com/nvim-treesitter/nvim-treesitter/blob/mast...

nvim-treesitter/nvim-treesitter (to provide a simple and easy way to use the interface for tree-sitter in Neovim and to provide some basic functionality such as highlighting based on it)

I suggest looking for blog posts about this, you're gunnuh wanna pick out a plugin manager and stuff. It's kind of like a package manager for neovim. You can install everything manually but usually you manually install a plugin manager and it gives you commands to manage the rest of your plugins.

These two plugins are the bare minimum in my view.

Treesitter gives you much better syntax highlighting based on a parser for a given language.

This plugin helps you connect to a given language LSP quickly with sensible defaults. You more or less pick your language from here and copy paste a snippet, and then install the relevant LSP:

For Python you'll want pylsp. For JavaScript it will depend on what frontend framework you're using, I probably can't help you there.

pylsp itself takes some plugins and you'll probably want them. https://github.com/python-lsp/python-lsp-server

Best of luck! Happy hacking.
