Canopy

Section titled “Canopy”

Canopy is a parser compiler targeting Java, JavaScript, Python and Ruby. It takes a file describing a [parsing expression grammar][1] and compiles it into a parser module in the target language. The generated parsers have no runtime dependency on Canopy itself.

For usage documentation see [canopy.jcoglan.com][2].

See CONTRIBUTING.md for instructions for building the project.
