A mostly functional interpreter for the piet esolang.

Run it with echo "" | cargo run /path/to/image.format

Sample programs (most of which work) can be found here.

Things that it does:

• Parse programs from most image formats
• Relatively faithfully execute those programs to spec

Things that I want it to eventually do:

• Run even with nothing passed to stdin
• Pre-compute more things about regions
• Wrap everything up in WASM and build out a frontend that lets you step through execution
• Have a web-based editor
• Not be a complete mess
