utility lib to generate python package version infos from mercurial tags
Project description
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:
try to directly ask hg for the tag/distance
try to infer it from the .hg_archival.txt file
try to use the cache file if it exists
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 usage doesn’t yet support cachefile.
