Reg: Clever Registries and Lookups

Reg is a Python library that provides generic function support to Python. It help you build powerful registration and configuration APIs for your application, library or framework.

Documentation.

CHANGES

0.8 (2014-08-28)

  • Added a @reg.classgeneric. This is like @reg.generic, but the first argument is treated as a class, not as an instance. This makes it possible to replace @classmethod with a generic function too.
  • Fix documentation on running documentation tests. For some reason this did not work properly anymore without running sphinxpython explicitly.
  • Optimization: improve performance of generic function calls by employing lookup_mapply instead of general mapply, as we only care about passing in the lookup argument when it’s defined, and any other arguments should work as before. Also added a perf.py which is a simple generic function timing script.

0.7 (2014-06-17)

  • Python 2.6 compatibility. (Ivo van der Wijk)
  • Class maps (and thus generic function lookup) now works with old style classes as well.
  • Marked as production/stable now in setup.py.

0.6 (2014-04-08)

  • Removed unused code from mapply.py.
  • Typo fix in API docs.

0.5 (2014-01-21)

  • Make reg.ANY public. Used for predicates that match any value.

0.4 (2014-01-14)

  • arginfo has been totally rewritten and is now part of the public API of reg.

0.3 (2014-01-06)

  • Experimental Python 3.3 support thanks to the future module.

0.2 (2013-12-19)

  • If a generic function implementation defines a lookup argument that argument will be the lookup used to call it.
  • Added reg.mapply(). This allows you to call things with more keyword arguments than it accepts, ignoring those extra keyword args.
  • A function that returns None is not assumed to fail, so no fallback to the original generic function is triggered anymore.
  • An optional precalc facility is made available on Matcher to avoid some recalculation.
  • Implement a specific PredicateMatcher that matches a value on predicate.

0.1 (2013-10-28)

  • Initial public release.
