This is a work in progress hobby project. If you are looking for a production ready parser generator for Rust, consider pest, lalrpop or nom. If you are looking for a production grade IDE-ready parser generator, take a look at Grammar Kit or Papa Carlo. You might also find tree-sitter to be interesting. The ambitious goal is to create a parsing framework, suitable for tools interacting with the source code, such as editors, IDEs, refactoring tools or code formatters.
