setuptools_scm-1.15.7-py2.7.egg-info
Metadata-Version: 1.1 Name: setuptools-scm Version: 1.15.7 Summary: the blessed package to manage your versions by scm tags Home-page: https://github.com/pypa/setuptools_scm/ Author: Ronny Pfannschmidt Author-email: opensource@ronnypfannschmidt.de License: MIT Description: setuptools_scm =============== :code:`setuptools_scm` handles managing your python package versions in scm metadata instead of declaring them as the version argument or in a scm managed file. It also handles file finders for the supported scm's. .. image:: https://travis-ci.org/pypa/setuptools_scm.svg?branch=master :target: https://travis-ci.org/pypa/setuptools_scm Setup.py usage -------------- To use setuptools_scm just modify your project's setup.py file like this: 1. Add :code:`'setuptools_scm'` to the :code:`setup_requires` parameter 2. Add the :code:`use_scm_version` parameter and set it to ``True`` E.g.: .. code:: python from setuptools import setup setup( ..., use_scm_version=True, setup_requires=['setuptools_scm'], ..., ) Arguments to ``get_version()`` (see below) may be passed as a dictionary to ``use_scm_version``. For example: .. code:: python from setuptools import setup setup( ..., use_scm_version = {"root": "..", "relative_to": __file__}, setup_requires=['setuptools_scm'], ..., ) 3. Access the version number in your package via :code:`pkg_resources` E.g. (`PEP-0396 <https://www.python.org/dev/peps/pep-0396>`_): .. code:: python from pkg_resources import get_distribution, DistributionNotFound try: __version__ = get_distribution(__name__).version except DistributionNotFound: # package is not installed pass Programmatic usage ------------------ In order to use ``setuptools_scm`` from code that is one directory deeper than the project's root, you can use: .. code:: python from setuptools_scm import get_version version = get_version(root='..', relative_to=__file__) See `setup.py Usage`_ above for how to use this within setup.py. Usage from sphinx ----------------- It is discouraged to use setuptools_scm from sphinx itself, instead use ``pkg_resources`` after editable/real installation: .. code:: python from pkg_resources import get_distribution release = get_distribution('myproject').version # for example take major/minor version = '.'.join(release.split('.')[:2]) The underlying reason is, that services like readthedocs sometimes change the workingdirectory for good reasons and using the installed metadata prevents using needless volatile data there. Notable Plugins ---------------- `setuptools_scm_git_archive <https://pypi.python.org/pypi/setuptools_scm_git_archive>`_ provides partial support for obtaining versions from git archives that belong to tagged versions. The only reason for not including it in setuptools-scm itself is git/github not supporting sufficient metadata for untagged/followup commits, which is preventing a consistent UX. Default versioning scheme -------------------------- In the standard configuration setuptools_scm takes a look at 3 things: 1. latest tag (with a version number) 2. the distance to this tag (e.g. number of revisions since latest tag) 3. workdir state (e.g. uncommitted changes since latest tag) and uses roughly the following logic to render the version: :code:`no distance and clean`: :code:`{tag}` :code:`distance and clean`: :code:`{next_version}.dev{distance}+{scm letter}{revision hash}` :code:`no distance and not clean`: :code:`{tag}+dYYYMMMDD` :code:`distance and not clean`: :code:`{next_version}.dev{distance}+{scm letter}{revision hash}.dYYYMMMDD` The next version is calculated by adding ``1`` to the last numeric component of the tag. For git projects, the version relies on `git describe <https://git-scm.com/docs/git-describe>`_, so you will see an additional ``g`` prepended to the ``{revision hash}``. Semantic Versioning (SemVer) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Due to the default behavior it's necessary to always include a patch version (the ``3`` in ``1.2.3``), or else the automatic guessing will increment the wrong part of the semver (e.g. tag ``2.0`` results in ``2.1.devX`` instead of ``2.0.1.devX``). So please make sure to tag accordingly. .. note:: Future versions of setuptools_scm will switch to `SemVer <http://semver.org/>`_ by default hiding the the old behavior as an configurable option. Builtin mechanisms for obtaining version numbers -------------------------------------------------- 1. the scm itself (git/hg) 2. :code:`.hg_archival` files (mercurial archives) 3. PKG-INFO .. note:: git archives are not supported due to git shortcomings Configuration Parameters ------------------------------ In order to configure the way ``use_scm_version`` works you can provide a mapping with options instead of simple boolean value. The Currently supported configuration keys are: :root: cwd relative path to use for finding the scm root, defaults to :code:`.` :version_scheme: configures how the local version number is constructed. either an entrypoint name or a callable :local_scheme: configures how the local component of the version is constructed either an entrypoint name or a callable :write_to: declares a text file or python file which is replaced with a file containing the current version. its ideal or creating a version.py file within the package .. warning:: only :code:`*.py` and :code:`*.txt` have builtin templates, for other extensions it is necessary to provide a :code:`write_to_template` :write_to_template: a newstyle format string thats given the current version as the :code:`version` keyword argument for formatting :relative_to: a file from which root may be resolved. typically called by a script or module that is not in the root of the repository to direct setuptools_scm to the root of the repository by supplying ``__file__``. :parse: a function that will be used instead of the discovered scm for parsing the version, use with caution, this is a expert function and you should be closely familiar with the setuptools_scm internals to use it To use setuptools_scm in other Python code you can use the ``get_version`` function: .. code:: python from setuptools_scm import get_version my_version = get_version() It optionally accepts the keys of the ``use_scm_version`` parameter as keyword arguments. Environment Variables --------------------- :SETUPTOOLS_SCM_PRETEND_VERSION: when defined and not empty, its used as the primary source for the version number in which case it will be a unparsed string Extending setuptools_scm ------------------------ setuptools_scm ships with a few setuptools entrypoints based hooks to extend its default capabilities. Adding a new SCM ~~~~~~~~~~~~~~~~ setuptools_scm provides 2 entrypoints for adding new SCMs ``setuptools_scm.parse_scm`` A function used to parse the metadata of the current workdir using the name of the control directory/file of your SCM as the entrypoint's name. E.g. for the built-in entrypoint for git the entrypoint is named :code:`.git` and references :code:`'setuptools_scm.git:parse'`. The return value MUST be a :code:`setuptools.version.ScmVersion` instance created by the function :code:`setuptools_scm.version:meta`. ``setuptools_scm.files_command`` Either a string containing a shell command that prints all SCM managed files in its current working directory or a callable, that given a pathname will return that list. Also use then name of your SCM control directory as name of the entrypoint. Version number construction ~~~~~~~~~~~~~~~~~~~~~~~~~~~ ``setuptools_scm.version_scheme`` Configures how the version number is constructed given a :code:`setuptools.version.ScmVersion` instance and should return a string representing the version. Available implementations: :guess-next-dev: automatically guesses the next development version (default) :post-release: generates post release versions (adds :code:`postN`) ``setuptools_scm.local_scheme`` Configures how the local part of a version is rendered given a :code:`setuptools.version.ScmVersion` instance and should return a string representing the local version. Available implementations: :node-and-date: adds the node on dev versions and the date on dirty workdir (default) :dirty-tag: adds :code:`+dirty` if the current workdir has changes Importing in setup.py ~~~~~~~~~~~~~~~~~~~~~ To support usage in :code:`setup.py` passing a callable into use_scm_version is supported. Within that callable, setuptools_scm is available for import. The callable must return the configuration. .. code:: python def myversion(): from setuptools_scm.version import dirty_tag def clean_scheme(version): return dirty_tag(version) if version.dirty else '+clean' return {'local_scheme': clean_scheme} Code of Conduct --------------- Everyone interacting in the setuptools_scm project's codebases, issue trackers, chat rooms, and mailing lists is expected to follow the `PyPA Code of Conduct`_. .. _PyPA Code of Conduct: https://www.pypa.io/en/latest/code-of-conduct/ Platform: UNKNOWN Classifier: Development Status :: 4 - Beta Classifier: Intended Audience :: Developers Classifier: License :: OSI Approved :: MIT License Classifier: Programming Language :: Python Classifier: Programming Language :: Python :: 3 Classifier: Programming Language :: Python :: 2.6 Classifier: Programming Language :: Python :: 2.7 Classifier: Programming Language :: Python :: 3.3 Classifier: Programming Language :: Python :: 3.4 Classifier: Programming Language :: Python :: 3.5 Classifier: Programming Language :: Python :: 3.6 Classifier: Topic :: Software Development :: Libraries Classifier: Topic :: Software Development :: Version Control Classifier: Topic :: System :: Software Distribution Classifier: Topic :: Utilities
