hgdistver 0.15

utility lib to generate python package version infos from mercurial tags

This module is a simple drop-in to support setup.py in mercurial based projects.

Alternatively it can be a setup time requirement.

Its supposed to generate version numbers from mercurials meta-data. It tries to use the current tag and falls back to the next reachable tagged ancestor and using the distance to it as .post marker.

It uses 4 strategies to archive its task:

1. try to directly ask hg for the tag/distance

2. try to infer it from the .hg_archival.txt file

3. try to use the cache file if it exists

4. try to read the version from the ‘PKG-INFO’ file sdists contain (this is a nasty abuse)

The most simple usage is:

from setuptools import setup
from hgdistver import get_version
setup(
    ...,
    version=get_version(),
    ...,
)

get_version takes the optional argument cachefile, which causes it to store the version info in a python script instead of abusing PKG-INFO from a sdist.

The setup requirement usage is:

from setuptools import setup
setup(
    ...,
    get_version_from_hg=True,
    setup_requires=['hgdistver'],
    ...,
)

The requirement uses the setup argument cache_hg_version_to instead of cachefile.
