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
