Org grammar for tree-sitter. Here, the goal is to implement a grammar that can usefully parse org files to be used in any library that uses tree-sitter parsers. It is not meant to implement emacs' orgmode parser exactly, which is inherently more dynamic than tree-sitter easily allows.
This section is meant to be a quick reference, not a thorough description.
Refer to the tests in corpus for examples.
- Top level node:
(document) - Document contains:
(directive)* (body)? (section)* - Section contains:
(headline) (plan)? (property_drawer)? (body)? - headline contains:
((stars), (item)?, (tag_list)?) - body contains:
(element)+ - element contains:
(directive)* choose(paragraph, drawer, comment, footnote def, list, block, dynamic block, table)or a bare(directive) - paragraph contains:
(expr)+ - expr contains: anonymous nodes for 'str', 'num', 'sym', and any ascii symbol that is not letters or numbers. (See top of grammar.js and queries for details)
Like in many regex systems, */+ is read as "0/1 or more", and ? is 0 or 1.

For manual install, use make.
For neovim, using nvim-treesitter/nvim-treesitter, add to your configuration:
local parser_config = require "nvim-treesitter.parsers".get_parser_configs()
parser_config.org = {
install_info = {
url = 'https://github.com/milisims/tree-sitter-org',
revision = 'main',
files = { 'src/parser.c', 'src/scanner.c' },
},
filetype = 'org',
}To build the parser using npm and run tests:
- Install node.js as described in the tree-sitter documentation
- Clone this repository:
git clone https://github.com/milisims/tree-sitter-organdcdinto it - Install tree-sitter using npm:
npm install - Run tests:
./node_modules/.bin/tree-sitter generate && ./node_modules/.bin/tree-sitter test
