Chuff!

Chuff is a huff-language parser with a focus on error recovery. It can produce partial AST's even when user input is incorrect.

Warning Mard is currently under active development and is not suited for production use. Go for it, but it probably won't do what you want it to.

Wat do?

Chuff is a huff parser build with chumsky. A "parser library for humans with powerful error recovery". Using chumsky as a base reduces the effort to build a parser that can recover from errors, which is essential to provide as much feedback as possible within an lsp.

Why

lsp

This software is being written to start the effort in creating a functional lsp for huff. Huff is a hard language to learn as there are so many footguns. Creating an LSP aims to provide feedback to people learning that will reduce the pain of it all.

While writing the lsp, I repeatedly came across issues regarding error recovery originating from the original compiler ( it was not designed to be run in response to every user input ). This project was born to learn rust and the internals of an error resistant parser before making the required changes to the existing compiler.

TODO
