Tree-sitter CLI

crates.io badge npmjs.com badge

The Tree-sitter CLI allows you to develop, test, and use Tree-sitter grammars from the command line. It works on MacOS, Linux, and Windows.

Installation

You can install the tree-sitter-cli with cargo-binstall:

cargo binstall tree-sitter-cli

or you can build it from source:

cargo install --locked tree-sitter-cli

You can also download a pre-built binary for your platform from the releases page.

Dependencies

The tree-sitter binary itself has no dependencies, but specific commands have dependencies that must be present at runtime:

  • To generate a parser from a grammar, you must have node on your PATH.
  • To run and test parsers, you must have a C and C++ compiler on your system.

Commands

  • generate - The tree-sitter generate command will generate a Tree-sitter parser based on the grammar in the current working directory. See the documentation for more information.

  • test - The tree-sitter test command will run the unit tests for the Tree-sitter parser in the current working directory. See the documentation for more information.

  • parse - The tree-sitter parse command will parse a file (or list of files) using Tree-sitter parsers.
