Usage

To use, simply inherit from ~ctorrepr.CtorRepr then implement its ~ctorrepr.CtorRepr._collect_repr_args() to match your existing __init__() method:

>>> from ctorrepr import CtorRepr
>>> class X(CtorRepr):
...     def __init__(self, x1='x1', x2='x2', *poargs, **kwargs):
...         super().__init__(*poargs, **kwargs)
...         self.x1 = x1
...         self.x2 = x2
...     def _collect_repr_args(self, poargs, kwargs):
...         super()._collect_repr_args(poargs, kwargs)
...         poargs[:0] = self.x1, self.x2
>>> class Y(CtorRepr):
...     def __init__(self, *y, **kwargs):
...         super().__init__(**kwargs)
...         self.y = y          # completely consumes positional args
...     def _collect_repr_args(self, poargs, kwargs):
...         super()._collect_repr_args(poargs, kwargs)
...         poargs[:0] = self.y
>>> class Z(CtorRepr):
...     def __init__(self, *poargs, zk='zk', **kwargs):
...         super().__init__(*poargs, **kwargs)
...         self.zk = zk
...     def _collect_repr_args(self, poargs, kwargs):
...         super()._collect_repr_args(poargs, kwargs)
...         kwargs.update(zk=self.zk)
>>> class W(X, Y, Z):
...     def __str__(self):
...         return repr(self)
>>> print(' '.join(t.__name__ for t in W.mro()))
W X Y Z CtorRepr object
>>> print(W())
W('x1', 'x2', zk='zk')
>>> print(W(24))
W(24, 'x2', zk='zk')
>>> w = W(24, 25, 'y1', 'y2')
>>> w.y
('y1', 'y2')
>>> print(w)
W(24, 25, 'y1', 'y2', zk='zk')
>>> print(W(zk=100))
W('x1', 'x2', zk=100)
