nix run for your treesitter grammars and arbitrary plugins

Provides commands to easily install treesitter grammars and plugins temporarily.

Setup

put this in your init.lua

require('nixrun').setup({})

Usage

These commands are provided

NixRunTSGrammar # installs a treesitter parser
NixRunPlugin    # installs a vim plugin

• Treesitter parsers are taken from nixpkgs#vimPlugins.nvim-treesitter.builtGrammars

• Plugins are taken from nixpkgs#vimPlugins, or a custom flake: yourFlake#some-plugin, or a flakeref URL: github:t-troebst/perfanno.nvim

• Tab completion is available for the simple nixpkgs parsers/plugins

Example

Installing treesitter grammars:

:NixRunTSGrammar java

Refresh your buffer (with :edit) after the install completes: you will get a notification when that happens.

Note

• I recommend you pin your nixpkgs registry by adding this to your NixOS/home-manager config (mismatched neovim and grammar versions might cause unexpected errors):

  nix.registry.nixpkgs.flake = inputs.nixpkgs;
