Koopa is a parser generator, made for Cobol. It can handle source files in isolation (no preprocessing required) and doesn't mind the presence of CICS/SQL fragments. The grammar is easily extensible in a way which minimizes the impact on the overall code.


  • Parser generator
  • Cobol lexer and grammar which accepts fixed, free and variable format code
  • Basic parsers for embedded CICS and SQL
  • Basic Cobol preprocessor
  • Covered by a Cobol 85 testsuite, and grammar unit testing
  • Cobol code viewer with syntax highlighting, outline, quick navigation and XPath-based querying
  • XML dumps of parse trees
