oswhich 0.1.0

oswhich

This package allows for cross-platform implementations on-the-go with a very sugary decorator syntax. It works also for classes, its methods and properties. Although, development is still incipient so feel free to open an issue on the bug tracker.

Examples

from oswhich import linux, macosx, windows, solaris

@linux
def f(x):
    return 2 * x

@macosx
def f(x):
    return x ** 2

@windows
def f(x):
    return x + 2

>>> f(3) # in Linux
6
>>> f(3) # in MacOSx
9
>>> f(3) # in Windows
5
>>> f(3) # in Solaris
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
RuntimeError: Sorry, function `f` was not implemented for your platform. 

Advanced usage

You may define your own definition selector. Internally, OsWhich relies on platform.system() to select current platform. If OsWhich.__init__ takes a string as parameter, it just compares it with platform.system()'s output. If you pass a callable to the constructor, you are allowed to do whatever you want, as long as this function follows the signature foo(system: str) -> bool.

from oswhich import OsWhich

mysystem = OsWhich(foo)

@mysystem
def f(x):
    return -x
