Set Python wheel version tag dynamically

I'm trying to integrate building of a wheel file into a Bamboo plan. Ultimately, I'd like to tie part of the version tag of the .whl file to the Bamboo build number in someway, i.e. the pre-release for version 0 would be 0.dev1, 0.dev2, 0.dev3 for successive builds.

The old egg format used to allow the --tag_build option, which would allow you to specify a tag that is appended to the version parameter defined in the setup function in the setup.py file. The bdist_wheel command apparently doesn't have an equivalent option.

This dashed my hopes of running setup.py from a script, using the Bamboo build number variable. I'm looking for any other suggestions other than either converting the build script to Powershell, or generating setup.py on the fly each build.

The version tag in the wheel filename is just the package version number, defined by setup.py, and setup.py is a Python script with all the power of Python available to it. Thus, setup.py can simply set the version parameter of the setup() function based on the bamboo_buildNumber environment variable:

import os

version = whatever_the_version_would_be_otherwise
try:
    version += '.dev' + os.environ['bamboo_buildNumber']
except KeyError:  # bamboo_buildNumber isn't defined, so we're not running in Bamboo
    pass

setup(
    version = version,
    ...
)
