pest-ast

This is an in-development add-on to the pest parsing library.

Pest-ast provides a structured manner to go from the "dynamically typed" Pest Parse Tree to a strongly typed (Abstract) Syntax Tree, as well as a derive to do so automatically. In the future, it's planned to optionally additionally check the source grammar to statically prevent issues that are currently detected at runtime.

In the future 🦄, pest-ast may provide a way of defining grammar directly on the AST nodes.

Note:

This crate is actually from-pest, which provides the trait framework for the said conversion. pest-ast provides the actual derive for the conversion.

This README is the root of the repository for legacy reasons. This will be corrected in a future reorganization.

Contributing

Check out the issue tracker; we try to keep it stocked with good-first-issue and help-wanted opportunities. If you have questions, don't be afraid to @ the author (CAD97) on Gitter or on Discord. The best thing you can probably do for this library currently is to use it! More than anything else, I just want eyes on the interface trying it out and seeing where it shines and wher it falters.
