tree-sitter-dart
A tree-sitter grammar for the Dart programming language — which also covers Flutter (Flutter widgets are ordinary Dart classes; there is no separate Flutter syntax).
This is a fork of UserNobody14/tree-sitter-dart
(MIT) packaged and published as a Python distribution with pre-compiled
wheels (Linux/macOS/Windows), since no tree-sitter-dart existed on PyPI
compatible with tree-sitter>=0.23.
Python usage
pip install tree-sitter-dart # ships pre-compiled wheels; no C compiler needed
import tree_sitter_dart
from tree_sitter import Language, Parser
parser = Parser(Language(tree_sitter_dart.language()))
tree = parser.parse(b"class MyWidget extends StatelessWidget { Widget build(c) {} }")
print(tree.root_node.type) # -> program
language() returns a tree_sitter.Language PyCapsule, the standard
py-tree-sitter interface. Wheels are abi3 (CPython 3.8+).
Grammar development (Node / tree-sitter CLI)
This is a tree-sitter grammar written for the dart programming language. We attempt to adhere as closely as possible to the dart language spec. Initially it was started with a copy of the tree-sitter Java grammar which is why there may be a few relics included in here. For the sake of simplifying the syntax tree, many items were made inlined with tree-sitter's "underscore" method of writing rules.
Getting started
- Go to the project directory
- run
npm install(first time) - run
npm run build_init(first time)npm run build(subsequent times) - run
npm run test
To test a single highlight file
- run
tree-sitter highlight test/highlight/types.dart
To test a single test file
- run
tree-sitter test -f 'testcasefilter' - for example
tree-sitter test -f 'dart string literals'
To show the output of a parse for a sample file (for example while debugging highlight issues)
- run
tree-sitter parse path/to/file.dart
Credits
Grammar by UserNobody14 and contributors (MIT). This fork adds Python packaging, a modernized PyCapsule binding, and pre-compiled wheels.
