Description:
pythonexports 1.2.0
python-exports
The DRY alternative to __all__
Installation
To install the exports package, you can use
python-exports on PyPI:
pip install python-exports
Usage
>>> from exports import export
Now you can use it to add to __all__ as
function decorator
>>> @export
... def spam():
... ...
class decorator:
>>> @export
... class Ham:
... ...
by name:
>>> from functools import reduce as fold
>>> export('fold')
Behaviour
If the module has no __all__, it is created.
Otherwise, __all__ is converted to a list, and the export is appended.
Caveats
Exporting a function or class directly relies on the __name__ attribute,
so consider the following example:
>>> def eggs():
... ...
>>> fake_eggs = eggs
If we want to export fake_eggs, then this will not work:
>>> export(fake_eggs) # BAD: this will add `'eggs'` to `__all__`
In such cases, use the name instead:
>>> export('fake_eggs') # GOOD
You'll be safe if you either
decorate a function or a class directly with @export,
pass the name string when using plain export('...') calls.
