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