Haskell interface to Python

What is MissingPy?

It's two things:

  1. A Haskell binding for many C and Python libraries for tasks such as data compression, databases, etc. This can be found in the MissingPy module tree.

  2. A low-level Haskell binding to the Python interpreter to enable development of hybrid applications that use both environments. This can be found in the Python module tree. The Haskell bindings above use this environment.

MissingPy permits you to call Python code from Haskell. It does NOT permit you to call Haskell code from Python.

Major Features

  • GZip and BZip2 compression and decompression using the generic Handle-like HVIO interface

  • *dbm persistent storage using the generic AnyDBM interface

  • Low-level interface to Python for extending your own Haskell code

  • Many unit tests to verify proper functionality

** THIS IS CURRENTLY BETA-QUALITY CODE; MAJOR API FLUCTUATIONS MAY YET OCCUR.

Quick Start

See the file INSTALL.

Usage in programs

You can simply use -package MissingPy in ghc to enable this library.

Note that you'll want to compile most of your programs with -fallow-overlapping-instances at least. (If you use only MissingPy/*, that may not be necessary.) Also, please note that you must call Python.Interpreter.py_initialize before doing anything else.

The API docs can be built with "make doc", or you can find them at:
