tree-sitter-rust VS neovide

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?

Have you looked at Neovide? It's very similar to this, a cross-platform Rust based front end for neovim. Neovide is really quite nice it's beautifully rendered.

My primary use case for Neovide (vs neovim running in Wezterm/kitty/Alacritty) is simply so I can Alt/Cmd-TAB to it quickly as I usually run with many terminal windows open and it's somewhat of a chore to locate the one with nvim in it, whereas with Neovide I have a separate app with an icon in the dock/sysmenu to switch to.

- have a “graphical” user interface: https://github.com/neovide/neovide

The process above works fine, though, depending on your setup and project, you might appreciate the benefits of a lean editor like Neovide. So, let’s see how to configure Neovim to run with Unreal Engine.

EDIT: I found this just now -> https://github.com/neovide/neovide/issues/1902 and disabling relative line numbers does indeed make the problem more or less disappear.

Not Emacs, but perhaps https://github.com/neovide/neovide will be of interest to you.

im certainly not a programmer , but NVIM with SOME gui like neovide it looks amazing and great,

Yes it is neovide: https://github.com/neovide/neovide

iTerm2, since Terminal.app doesn't support 24-bit colors and I used Neovim for some time. I now use Neovide for Neovim, so all I use iTerm2 for now is the UI (I have a theme I like, plus dark mode actually works).
