# Miniver [![license: CC0-1.0](https://img.shields.io/pypi/l/miniver.svg)][cc0] [![PyPI version](https://img.shields.io/pypi/v/miniver.svg)][pypi] [![CI status](https://github.com/jbweston/miniver/workflows/test/badge.svg)][ci] **Like [versioneer][versioneer], but smaller** Miniver is a **mini**mal **ver**sioning tool that serves the same purpose as [Versioneer][versioneer], except that it only works with Git and multiplatform support is still experimental. #### Why would I use this? If you are developing a Python package inside a Git repository and want to get the version directly from Git tags, rather than hard-coding version strings everywhere. This is the same problem that Versioneer solves, but Miniver is less than 200 lines of code, whereas Versioneer is over 2000. The tradeoff is that Miniver only works with Git and Python 3.5 (or above). Support for Python 2 is not a goal, as Python 2 is fast approaching its end of life (2020), and we want to encourage people to use Python 3! That being said, Christian Marquardt has a [fork that also works with Python 2](https://github.com/cmarquardt/miniver2) [versioneer]: https://github.com/warner/python-versioneer [cc0]: http://creativecommons.org/publicdomain/zero/1.0/ [pypi]: https://pypi.org/project/miniver/ [ci]: https://github.com/jbweston/miniver/actions?query=workflow%3Atest ## Usage The simplest way to use Miniver is to run the following in your project root: ``` curl https://raw.githubusercontent.com/jbweston/miniver/master/bin/miniver | python - install ``` This will grab the latest files from GitHub and set up Miniver for your project. ### I get an `unknown` version! The version is reported as `unknown` (plus the current git hash) when there are no valid tags in the git history. You should create an [*annotated tag*](https://git-scm.com/book/en/v2/Git-Basics-Tagging) so that Miniver reports a reasonable version. If your project uses *unannotated tags* for versioning (though this is not the [recommended way](https://stackoverflow.com/questions/11514075/what-is-the-difference-between-an-annotated-and-unannotated-tag)) then you'll need to run the following in order to modify Miniver's behaviour: ``` curl https://raw.githubusercontent.com/jbweston/miniver/master/unannotated-tags.patch | patch /_version.py ``` ### I don't want to type that URL every time I use this You can `pip install miniver`, which will give you the `miniver` command. Then you can simply run the following from your project root to use Miniver: ``` miniver install ``` ### Can I use this without executing random code from the internet? Sure! Copy `miniver/_version.py` and `miniver/_static_version.py` from this repository into your package directory, then copy the following snippets into the appropriate files: ```python # Your package's __init__.py from ._version import __version__ del _version ``` ```python # Your project's setup.py # Loads _version.py module without importing the whole package. def get_version_and_cmdclass(package_name): import os from importlib.util import module_from_spec, spec_from_file_location spec = spec_from_file_location('version', os.path.join(package_name, '_version.py')) module = module_from_spec(spec) spec.loader.exec_module(module) return module.__version__, module.cmdclass version, cmdclass = get_version_and_cmdclass('my_package') setup( name='my_package', version=version, cmdclass=cmdclass, ) ``` ``` # Your project's .gitattributes my_package/_static_version.py export-subst ``` replacing `'my_package'` in the above with the name of your package (this should be the same as the name of the directory into which you copied the contents of `miniver`).
