Moose-like object system for Python
import elk class Point(elk.Elk): x = elk.ElkAttribute(mode='rw', type=int) y = elk.ElkAttribute(mode='rw', type=int) def clear(self): self.x = 0 self.y = 0 class Point3D(Point): z = elk.ElkAttribute(mode='rw', type=int) @elk.after('clear') def clear_z(self): self.z = 0
What is Elk?
- attribute delegation
- default attribute values
- lazy attribute initialisation
- read-only attributes
- required attributes
- attribute type constraints
- method modifiers
Elk is written in pure Python and there are no dependencies beyond the standard library.
How does Elk differ from Moose?
Moose has many features that are not (yet) implemented in Elk.
While Elk tries to faithfully implement Moose paradigms and patterns in Python, it uses Python idioms and language features as much as possible. There are also some differences in terminology in order to be consistent with Python terminology or idioms.
There is not yet a namespace for Elk extensions, nor any convenient mechanism for extending it.
