chide 3.0.0

Quickstart

Say we have two classes that each require two parameters in order to be instantiated:

from dataclasses import dataclass

@dataclass
class ClassOne:
  x: int
  y: int

@dataclass
class ClassTwo:
  a: int
  b: ClassOne

We can set up a registry of sample values as follows:

from chide import Collection

samples = Collection({
    ClassOne: {'x': 1, 'y': 2},
    ClassTwo: {'a': 1, 'b': ClassOne},
})

Now we can quickly make sample objects:

>>> samples.make(ClassOne)
ClassOne(x=1, y=2)

We can provide our own overrides if we want:

>>> samples.make(ClassOne, y=3)
ClassOne(x=1, y=3)

We can also create nested trees of objects:

>>> samples.make(ClassTwo)
ClassTwo(a=1, b=ClassOne(x=1, y=2))
