ReScript grammar for Tree-sitter

This repository contains a parser definition of the ReScript language for the Tree-sitter parser generator tool.

Athough Tree-sitter has many applications, the main intent of this parser is powering the nvim-treesitter-rescript NeoVim plugin which may be used to improve development experience in the NeoVim + ReScript combo.

Queries for text objects are also included which help you to navigate, select, and modify ReScript code syntactically. For NeoVim, the nvim-treesitter-textobjects plugin is required to use Tree-sitter text objects.

Installation

• If you want ReScript Tree-sitter in NeoVim, refer to nvim-treesitter-rescript installation notes;

Contributing

Contributions are welcome. Here’s how you can help:

🙂 Provide a minimal ReScript snippet which produces an (ERROR) node or otherwise incorrect syntax tree. Open a new issue providing this snippet and the resulting syntax tree. You can use the following command to see the syntax tree:

yarn tree-sitter parse /path/to/your/snippet.res

🤩 Add a failing test case for a snippet which is valid ReScript but produces an incorrect syntax tree. Fix the grammar.js. Make sure nothing is broken: make test test_wild shows 100% test success. Open a pull request.
