Generic programming library for Python

Project description

Generic programming library for Python

Build Status Maintainability Test Coverage Documentation Status Code style: black

Generic is a library for Generic programming, also known as Multiple dispatch.

The Generic library supports:

  • multi-dispatch: like functools.singledispatch, but for more than one parameter
  • multi-methods: multi-dispatch, but for methods
  • event dispatching: based on a hierarchical event structure (event objects)

You can read documentation hosted at excellent project. Development takes place on github.



  • Updated documentation on Readthedocs
  • Fix multimethod.otherwise clause


  • Ported the code to Python 3.7, Python 2 is no longer supported
  • Multimethods now have their own module
  • The interface now mimics functools.singledispatch:
    • the when method has been renamed to register
    • overriding of methods is no longer possible


  • Minor fixes in distribution.


  • Event management with event inheritance support.


  • Methods with multidispatch by object type and positional arguments.
  • Override multifunctions with override method.


  • Registry with simple and type axes.
  • Functions with multidispatch by positional arguments.
