bindings/rust/build.rs - This file wraps the building process for the Rust crate.

bindings/rust/lib.rs - This file wraps your language in a Rust crate when used in Rust.

bindings/node/ - This file wraps your language in a JavaScript object when used in Node.js.

bindings/node/index.js - This is the file that Node.js initially loads when using your language.

#Tree it tree generator how to#

binding.gyp - This file tells Node.js how to compile your language.The first time you run tree-sitter generate, it will also generate a few other files: After making changes to your grammar, just run tree-sitter generate again. This command reads the grammar.js file in your current working directory and creates a file called src/parser.c, which implements the parser.

The most important command youвЂ™ll use is tree-sitter generate. LetвЂ™s go over all of the functionality of the tree-sitter command line tool. The preferred convention is to name the parser repository вЂњtree-sitter-вЂњ followed by the name of the language. See the contributing docs for more information. Build the tree-sitter-cli Rust crate from source using cargo, the Rust package manager.Download a binary for your platform from the latest GitHub release, and put it into a directory on your PATH.This is the recommended approach, and it is discussed further in the next section.

Install the tree-sitter-cli Node.js module using npm, the Node package manager.

You can install the CLI in a few different ways: To create a Tree-sitter parser, you need to use the tree-sitter CLI. Tree-sitter will try to look for these compilers in the standard places for each platform.

In order to run and test these parsers with the tree-sitter parse or tree-sitter test commands, you must have a C/C++ compiler installed.

A C Compiler - Tree-sitter creates parsers that are written in C.

YouвЂ™ll need Node.js version 6.0 or greater. It requires the node command to be in one of the directories in your PATH.

Node.js - Tree-sitter grammars are written in JavaScript, and Tree-sitter uses Node.js to interpret JavaScript files.

In order to develop a Tree-sitter parser, there are two dependencies that you need to install: This document will help get you to get started and to develop a useful mental model. Developing Tree-sitter grammars can have a difficult learning curve, but once you get the hang of it, it can be fun and even zen-like.
