Chicken Chicken is an implementation of the Chicken esoteric language. It compiles Chicken source code to ES2020-compliant JavaScript.

It's written entirely in CHICKEN Scheme. 🐔

It aims to be fully compatible with the original Chicken implementation, while still being:

• Efficient: No parsing occurs at runtime.
• Tiny: It generates very tiny scripts. For big files (> 10KiB), compiler output will be 80% smaller.
• Convenient: The VM will happily produce readable output when asked; no HTML escape codes. You can still demand HTML escape codes by enabling compatibility mode.

All examples from the original Chicken implementation work properly with Chicken Chicken.

Install

Chicken Chicken is a self-contained static binary executable. Installation instructions can be found here.

If you wish to build it from source, instructions can be found here.

Usage

You can compile a Chicken script to JavaScript by doing:

chicken-chicken -o example.js example.chicken

You can compile with the --exec option and pipe the output to Node to run it:

chicken-chicken --exec example.chicken | node

Chicken Chicken can also generate ECMAscript modules and CommonJS modules, based on the flags given. The full documentation can be found here. 🐔
