In active development

Requirements

• python 3
• modules
  • cgen
  • nose

Building

Inside a virtualenv, pip install the dependencies.

$ pip install -r requirements.txt

Usage

$ python mypyc.py sample_python_scripts/hello_world.py  # creates sample_python_scripts/hello_world.c and sample_python_scripts/hello_world executable
$ ./sample_python_scripts/hello_world
Hello world

Testing

In the root directory of this repo, run

$ nosetests

TODO

• Have all conversion functions return a cgen.Generable type
• Handle type inference for assignment before converting the rest of the nodes in a body
• Figure out how to represent multiple tyes with the same variable
• Explore idea of storing wrapper objects inside containers (dicts, sets, lists)
• Implement conversion of control flow
  • with
  • break/continue
  • try/raiseing exceptions
• Reduce number of scoping using parenthesis by not encapsulating function calls or single variables or hardocded types. Only encapsulate expressions with parenthesis.
• Cleanup and modularize c_conversions.py
  • Cleanup the assignment functions
• Tests
  • Add unit tests
  • For degrees.py, use assertAlmostEqual to check the floating point outputs
  • Code generation for each integration test sample script
  • Come up with a test that involves assignment not using the test.py script
• Builtin data structures
  • Strings
  • Sets
  • Dictionaries
  • Lists
• Memoize expression type extractions
• Support function types/assignment
• Submit pull request to cgen for adding types
