nvim-treesitter-main

A Nixpkgs overlay for the nvim-treesitter plugin main branch rewrite

## Overview The [nvim-treesitter](https://github.com/nvim-treesitter/nvim-treesitter/tree/main) main branch is a full, incompatible rewrite of the project, and the existing `master` branch is all but abandoned. The `nixpkgs` `nvim-treesitter` plugin is not well equipped to handle the migration today, nor would it be a good idea to switch everyone over given the still-nascent ecosystem around the rewrite. Regardless, you're here because you're both a Nix and Neovim user, and you like to live on the bleeding edge. **nvim-treesitter-main** is a flake that builds the new `main` branch `nvim-treesitter`, along with all of the parser versions from the [`parsers.lua`](https://github.com/nvim-treesitter/nvim-treesitter/blob/main/lua/nvim-treesitter/parsers.lua) file, as recommended by the project. ## Usage In your flake.nix: ```nix inputs = { nvim-treesitter-main.url = "github:iofq/nvim-treesitter-main"; }; # ... and import the overlay pkgs = import nixpkgs { inherit system; overlays = [ inputs.nvim-treesitter-main.overlays.default ]; }; ``` ## Updating To update the list of parsers in `generated.nix`: ```bash nix flake update nix develop --command "generate-parsers" ``` This runs a lua script similar to the old [update.py](https://github.com/NixOS/nixpkgs/blob/master/pkgs/applications/editors/vim/plugins/utils/nvim-treesitter/update.py), but uses the `nvim-treesitter` as a source for version info instead of the NURR json file.
