Attempt to make a tree-sitter grammar for dart

tree-sitter-dart

This is a tree-sitter grammar written for the dart programming language. I attempted to adhere as closely as possible to the dart language spec. Initially I 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
