parboiled is a mixed Java/Scala library for lightweight, easy-to-use parsing of arbitrary text based on Parsing Expression Grammars (PEGs). It serves as a powerful alternative to regular expressions and traditional CFG-based parser generators.

Use cases

  • parse structured text with a PEG grammar in Java or Scala
  • replace complex regular expressions with readable parsers
  • build a DSL parser on the JVM
  • parse custom file formats or protocols
  • construct ASTs from input text with parse trees and value stacks

When to choose

  • you need elegant, lightweight parsing in Java or Scala without external tooling
  • regular expressions are too limited for your grammar
  • you want parser rules defined directly in code rather than generated from grammar files

When to avoid

  • you need maximum parsing performance for huge inputs
  • your project is not on the JVM
  • you prefer grammar-file-based parser generators like ANTLR
