tree-sitter-org
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.
Overview
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.

Install
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.cc' },
},
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-org
andcd
into it - Install tree-sitter using npm:
npm install
- Run tests:
./node_modules/.bin/tree-sitter generate && ./node_modules/.bin/tree-sitter test
