  • Supports parser actions, error recovery, and value stack manipulation for building ASTs
  • Successor to the popular Parboiled library, benefiting from lessons learned in that project
  • Open source and hostable/inspectable directly on GitHub

Recommended for

  • Java and JVM developers who want to build parsers without learning a separate grammar language
  • Projects needing custom domain-specific languages (DSLs) or configuration formats
  • Developers who prefer PEG semantics over ambiguous CFG-based tools like ANTLR
  • Teams that want parser logic kept inline in their codebase rather than generated
  • Prototyping and small-to-medium parsing tasks where fluent Java code is convenient
