Hello, has anyone created a survey of Python Object Systems? The two I am aware
of are:
- elk https://github.com/frasertweedale/elk
- Traits http://code.enthought.com/projects/traits/
Here's the ones from my talk at Pycon 2005
(http://www.vrplumber.com/programming/descriptors-pycon2005.pdf):
OpenGLContext/PyVRML97
http://bazaar.launchpad.net/~mcfletch/pyvrml97/trunk/files
Observable, auto-coercing data properties w/ Numeric/numpy array
support, defaults
BasicProperty (now largely abandoned):
http://bazaar.launchpad.net/~mcfletch/basicproperty/trunk/files
Again, observable auto-coercing typed properties, defaults,
introspection
Zope2
FieldProperty, DublinCore, Validation, Observability
PEAK
Defaults, delegation, implicit feature loading
Traits
Delegation, typing, validation, defaults, Observability, introspection
PyObjc, ctypes, JythonC, IronPython
Function-like things with lots of metadata
There's also a listing of the other tasks for which descriptors/object
systems were expected to show up at the time, if you look for Python +
that key-word you'll likely find a few dozen more "object systems" out
there. You'll also likely find about a thousand metaclasses these days.
HTH,
Mike
