Project Structure

  • com.freddieposer.scaly

    • application
    • AST
    • backend
      • pyc - Code for reading and writing compiled python files
      • internal - InternalSyntaxTree (IST) for representing code pre-compilation
    • typechecker - The TypeChecker generates an IST for use by the backend compiler
      • context
      • types
        • stdtypes - Types in the standard library
    • utils - Utility classes
    • tests - Simple test suite

  • test_suite - Each file is a single test

    • Files starting with an S_ are expected to pass, those with an F_ are expected to fail
    • Files in the compiler directory have their expected output at the top in a comment
