versionedfunction

Sometimes you want to be able to dynamically call different versions of a function.

• testing alternatives against each other
• runtime "always on" support for versions code changes

Example

from versionedfunction import versionedfunction, versionedcontext


class Foo():
    @versionedfunction
    def algo(self):
        return 0

    @algo.version
    def algo1(self):
        return 1

    @algo.version
    @algo.default
    def algo2(self):
        return 2


foo = Foo()

# the default is algo2
assert foo.algo() == 2

with versionedcontext(Foo.algo):
    # choose Foo.algo
    assert foo.algo() == 0

@versionedcontext(Foo.algo1)
def some_method():
    assert foo.algo() == 1

Installing

$ pip install versionedfunction

The source code is currently hosted on GitHub at https://github.com/GistLabs/versionedfunction and published in PyPI at https://pypi.org/project/versionedfunction/

The versioning scheme currently used is {major}.{minor}.{auto build number} from git rev-list --count HEAD.

We recommend picking a version like:

versionedfunction = "^0.9"
