This project has moved to GitHub ! The version here at SourceForge will remain for historic purpose.

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.

Features

  • 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

Project Samples

Overview of parsing results. Source view with syntax highlighting. XPath support for querying the parse tree. Go from the source to the related grammar rule.
