tree-sitter-just

WIP: Tree-sitter grammar for Justfiles (casey/just)

To use treesitter based highlighting, folds etc. the queries need to be added to the runtimepath, until I get a PR into nvim-treesitter/nvim-treesitter you can install this repo as a plugin using Plug/packer/manual clone etc. This plugin also adds a simple ftdetect plugin for detecting

Packer:

use "IndianBoy42/tree-sitter-just"

Plug

Plug 'IndianBoy42/tree-sitter-just'

Manual

git clone https://github.com/IndianBoy42/tree-sitter-just ~/.local/share/nvim/site/pack/tree-sitter-queries/start/tree-sitter-just

You can then do require('tree-sitter-just').setup() to register the parser with tree-sitter. You can then do TSInstall/TSUpdate as usual to install the parser

You can also add the parser manually using (This is similar to what is done in require"tree-sitter-just".setup())

require("nvim-treesitter.parsers").get_parser_configs().just = {
  install_info = {
    url = "https://github.com/IndianBoy42/tree-sitter-just", -- local path or git repo
    files = { "src/parser.c", "src/scanner.cc" },
    branch = "main",
  },
  maintainers = { "@IndianBoy42" },
}

Dont forget to :TSInstall after adding this. With this method you do not have to add this repo as a plugin

Testing

Building locally:

npm run gen
npm run test
tree-sitter parse test/test.just

You can use the nvim-treesitter/playground plugin from here, to explore the resulting parse tree. Use TSPlaygroundToggle to view the parse tree, and use TSHighlightCapturesUnderCursor to view highlight groups
