Crochet 🧣

A compile-to-JavaScript language with tight TypeScript integration. See design/mvp/README.md for information about planned features.

Development

External Requirements:

• rust with the wasm32-wasi target installed
• wasi-sdk
• cargo-watch
• node

Demo

To run the demo, run the following commands in seperate terminals:

• yarn watch-wasm
• yarn serve

Testing

• cargo insta test

Parser

The parser is broken down into two parts:

• a tree-sitter parser which generates a CST
• a rust-based parser which walks the CST and produces an AST

NOTE: The AST models functions as lambdas whereas the CST does not.

See crates/tree_sitter_crochet/README.md for details on how to modify the tree-sitter parser.
