Use git repo data (latest tag, current commit hash, etc) for building a version number according to PEP 440.

Features:

• Can be installed & configured through both setup.py and PEP 518's pyproject.toml
• Does not require to change source code of the project
• Tag-, file-, and callback-based versioning schemas are supported
• Templates for tag, dev and dirty versions are separated
• Templates support a lot of substitutions including git and environment information
• Well-documented

See comparison between setuptools-git-versioning and other tools.

Limitations:

• Currently the only supported VCS is Git
• Only Git v2 is supported
• Only Setuptools build backend is supported (no Poetry & others)
• Currently does not support automatic exporting of package version to a file for runtime use (but you can use setuptools-git-versioning > file redirect instead)

See https://setuptools-git-versioning.readthedocs.io/en/stable/

Just add setuptools-git-versioning to build-sytem section of your pyproject.toml, add a section tool.setuptools-git-versioning with config options, and mark the project version as dynamic.

[build-system]
requires = [ "setuptools>=41", "wheel", "setuptools-git-versioning>=3.0,<4", ]
build-backend = "setuptools.build_meta"

[tool.setuptools-git-versioning]
enabled = true

[project]
dynamic = ["version"]

And check the package version generated (see command help):

$ python -m setuptools_git_versioning
0.0.1

# or

$ setuptools-git-versioning
0.0.1

When add a git tag:

$ git add .
$ git commit -m "Test tagged"
$ git tag 1.2.3

And now version is based on git tag:

$ setuptools-git-versioning
1.2.3

$ echo 1 > uncommitted.change
$ git add .
$ setuptools-git-versioning
1.2.3.post0+git.d2bc6516.dirty

$ git commit -m "Test committed"
$ setuptools-git-versioning
1.2.3.post1+git.d452190b

Just add setuptools-git-versioning to setup_requires argument of setuptools.setup function call, and then add new argument setuptools_git_versioning with config options:

import setuptools

setuptools.setup(
    ...,
    setuptools_git_versioning={
        "enabled": True,
    },
    setup_requires=["setuptools-git-versioning>=3.0,<4"],
)

Commands are the same as above, plus python -m setup.py returns the same version.
