I'm pleased to announce Blip version 0.1.0, a bytecode compiler for Python 3. https://github.com/bjpop/blip Blip compiles Python 3 source files to bytecode. The output bytecode is compatible with the CPython interpreter (the "standard" Python implementation). For example, given a Python 3 source file called foo.py, the command: blip foo.py produces a bytecode file called foo.pyc. The bytecode can be executed by passing it as an argument to a CPython interpreter: python3 foo.pyc This is an early development release of Blip, so it is not ready for serious use, however it supports most of the Python 3 language already. It has been tested on OS X 10.7.5 with GHC 7.4.2. The output has been tested with Python 3.3.0.
