Rascal

CWI

💡 Choose it when source analysis and transformation matter as much as parsing and language definition.

Rascal is a domain-specific language for source-code analysis, transformation, and language development. It is intended for researchers and engineering teams building analyzers,...

Pros

Strong facilities for source-code analysis and transformation
Includes parsing, pattern matching, rewriting, and algebraic data types
Useful for language research and sophisticated program-processing tools

Cons

Requires learning the Rascal language rather than using a host-language API
Smaller ecosystem and fewer mainstream integrations than ANTLR
