The goal is to remove the tedious and error-prone "update -the embedded version string" step from your release process. Making a new -release should be as easy as recording a new tag in your version-control -system, and maybe making new tarballs. - - -## Quick Install - -* `pip install versioneer` to somewhere to your $PATH -* add a `[versioneer]` section to your setup.cfg (see below) -* run `versioneer install` in your source tree, commit the results - -## Version Identifiers - -Source trees come from a variety of places: - -* a version-control system checkout (mostly used by developers) -* a nightly tarball, produced by build automation -* a snapshot tarball, produced by a web-based VCS browser, like github's -  "tarball from tag" feature -* a release tarball, produced by "setup.py sdist", distributed through PyPI - -Within each source tree, the version identifier (either a string or a number, -this tool is format-agnostic) can come from a variety of places: - -* ask the VCS tool itself, e.g. "git describe" (for checkouts), which knows -  about recent "tags" and an absolute revision-id -* the name of the directory into which the tarball was unpacked -* an expanded VCS keyword ($Id$, etc) -* a `_version.py` created by some earlier build step - -For released software, the version identifier is closely related to a VCS -tag. Some projects use tag names that include more than just the version -string (e.g. "myproject-1.2" instead of just "1.2"), in which case the tool -needs to strip the tag prefix to extract the version identifier. For -unreleased software (between tags), the version identifier should provide -enough information to help developers recreate the same tree, while also -giving them an idea of roughly how old the tree is (after version 1.2, before -version 1.3). Many VCS systems can report a description that captures this, -for example `git describe --tags --dirty --always` reports things like -"0.7-1-g574ab98-dirty" to indicate that the checkout is one revision past the -0.7 tag, has a unique revision id of "574ab98", and is "dirty" (it has -uncommitted changes. - -The version identifier is used for multiple purposes: - -* to allow the module to self-identify its version: `myproject.__version__` -* to choose a name and prefix for a 'setup.py sdist' tarball - -## Theory of Operation - -Versioneer works by adding a special `_version.py` file into your source -tree, where your `__init__.py` can import it. This `_version.py` knows how to -dynamically ask the VCS tool for version information at import time. - -`_version.py` also contains `$Revision$` markers, and the installation -process marks `_version.py` to have this marker rewritten with a tag name -during the `git archive` command. As a result, generated tarballs will -contain enough information to get the proper version. - -To allow `setup.py` to compute a version too, a `versioneer.py` is added to -the top level of your source tree, next to `setup.py` and the `setup.cfg` -that configures it. This overrides several distutils/setuptools commands to -compute the version when invoked, and changes `setup.py build` and `setup.py -sdist` to replace `_version.py` with a small static file that contains just -the generated version data. - -## Installation - -First, decide on values for the following configuration variables: - -* `VCS`: the version control system you use. Currently accepts "git". - -* `style`: the style of version string to be produced. See "Styles" below for -  details. Defaults to "pep440", which looks like -  `TAG[+DISTANCE.gSHORTHASH[.dirty]]`. - -* `versionfile_source`: - -  A project-relative pathname into which the generated version strings should -  be written. This is usually a `_version.py` next to your project's main -  `__init__.py` file, so it can be imported at runtime. If your project uses -  `src/myproject/__init__.py`, this should be `src/myproject/_version.py`. -  This file should be checked in to your VCS as usual: the copy created below -  by `setup.py setup_versioneer` will include code that parses expanded VCS -  keywords in generated tarballs. The 'build' and 'sdist' commands will -  replace it with a copy that has just the calculated version string. - -  This must be set even if your project does not have any modules (and will -  therefore never import `_version.py`), since "setup.py sdist" -based trees -  still need somewhere to record the pre-calculated version strings. Anywhere -  in the source tree should do. If there is a `__init__.py` next to your -  `_version.py`, the `setup.py setup_versioneer` command (described below) -  will append some `__version__`-setting assignments, if they aren't already -  present. - -* `versionfile_build`: - -  Like `versionfile_source`, but relative to the build directory instead of -  the source directory. These will differ when your setup.py uses -  'package_dir='. If you have `package_dir={'myproject': 'src/myproject'}`, -  then you will probably have `versionfile_build='myproject/_version.py'` and -  `versionfile_source='src/myproject/_version.py'`. - -  If this is set to None, then `setup.py build` will not attempt to rewrite -  any `_version.py` in the built tree. If your project does not have any -  libraries (e.g. if it only builds a script), then you should use -  `versionfile_build = None`. To actually use the computed version string, -  your `setup.py` will need to override `distutils.command.build_scripts` -  with a subclass that explicitly inserts a copy of -  `versioneer.get_version()` into your script file. See -  `test/demoapp-script-only/setup.py` for an example. - -* `tag_prefix`: - -  a string, like 'PROJECTNAME-', which appears at the start of all VCS tags. -  If your tags look like 'myproject-1.2.0', then you should use -  tag_prefix='myproject-'. If you use unprefixed tags like '1.2.0', this -  should be an empty string, using either `tag_prefix=` or `tag_prefix=''`. - -* `parentdir_prefix`: - -  a optional string, frequently the same as tag_prefix, which appears at the -  start of all unpacked tarball filenames. If your tarball unpacks into -  'myproject-1.2.0', this should be 'myproject-'. To disable this feature, -  just omit the field from your `setup.cfg`. - -This tool provides one script, named `versioneer`. That script has one mode, -"install", which writes a copy of `versioneer.py` into the current directory -and runs `versioneer.py setup` to finish the installation. - -To versioneer-enable your project: - -* 1: Modify your `setup.cfg`, adding a section named `[versioneer]` and -  populating it with the configuration values you decided earlier (note that -  the option names are not case-sensitive): - -  ```` -  [versioneer] -  VCS = git -  style = pep440 -  versionfile_source = src/myproject/_version.py -  versionfile_build = myproject/_version.py -  tag_prefix = -  parentdir_prefix = myproject- -  ```` - -* 2: Run `versioneer install`. This will do the following: - -  * copy `versioneer.py` into the top of your source tree -  * create `_version.py` in the right place (`versionfile_source`) -  * modify your `__init__.py` (if one exists next to `_version.py`) to define -    `__version__` (by calling a function from `_version.py`) -  * modify your `MANIFEST.in` to include both `versioneer.py` and the -    generated `_version.py` in sdist tarballs - -  `versioneer install` will complain about any problems it finds with your -  `setup.py` or `setup.cfg`. Run it multiple times until you have fixed all -  the problems. - -* 3: add a `import versioneer` to your setup.py, and add the following -  arguments to the setup() call: - -        version=versioneer.get_version(), -        cmdclass=versioneer.get_cmdclass(), - -* 4: commit these changes to your VCS. To make sure you won't forget, -  `versioneer install` will mark everything it touched for addition using -  `git add`. Don't forget to add `setup.py` and `setup.cfg` too. - -## Post-Installation Usage - -Once established, all uses of your tree from a VCS checkout should get the -current version string. All generated tarballs should include an embedded -version string (so users who unpack them will not need a VCS tool installed). - -If you distribute your project through PyPI, then the release process should -boil down to two steps: - -* 1: git tag 1.0 -* 2: python setup.py register sdist upload - -If you distribute it through github (i.e. users use github to generate -tarballs with `git archive`), the process is: - -* 1: git tag 1.0 -* 2: git push; git push --tags - -Versioneer will report "0+untagged.NUMCOMMITS.gHASH" until your tree has at -least one tag in its history. - -## Version-String Flavors - -Code which uses Versioneer can learn about its version string at runtime by -importing `_version` from your main `__init__.py` file and running the -`get_versions()` function. From the "outside" (e.g. in `setup.py`), you can -import the top-level `versioneer.py` and run `get_versions()`. - -Both functions return a dictionary with different flavors of version -information: - -* `['version']`: A condensed version string, rendered using the selected -  style. This is the most commonly used value for the project's version -  string. The default "pep440" style yields strings like `0.11`, -  `0.11+2.g1076c97`, or `0.11+2.g1076c97.dirty`. See the "Styles" section -  below for alternative styles. - -* `['full-revisionid']`: detailed revision identifier. For Git, this is the -  full SHA1 commit id, e.g. "1076c978a8d3cfc70f408fe5974aa6c092c949ac". - -* `['dirty']`: a boolean, True if the tree has uncommitted changes. Note that -  this is only accurate if run in a VCS checkout, otherwise it is likely to -  be False or None - -* `['error']`: if the version string could not be computed, this will be set -  to a string describing the problem, otherwise it will be None. It may be -  useful to throw an exception in setup.py if this is set, to avoid e.g. -  creating tarballs with a version string of "unknown". - -Some variants are more useful than others. Including `full-revisionid` in a -bug report should allow developers to reconstruct the exact code being tested -(or indicate the presence of local changes that should be shared with the -developers). `version` is suitable for display in an "about" box or a CLI -`--version` output: it can be easily compared against release notes and lists -of bugs fixed in various releases. - -The installer adds the following text to your `__init__.py` to place a basic -version in `YOURPROJECT.__version__`: - -    from ._version import get_versions -    __version__ = get_versions()['version'] -    del get_versions - -## Styles - -The setup.cfg `style=` configuration controls how the VCS information is -rendered into a version string. - -The default style, "pep440", produces a PEP440-compliant string, equal to the -un-prefixed tag name for actual releases, and containing an additional "local -version" section with more detail for in-between builds. For Git, this is -TAG[+DISTANCE.gHEX[.dirty]] , using information from `git describe --tags ---dirty --always`. For example "0.11+2.g1076c97.dirty" indicates that the -tree is like the "1076c97" commit but has uncommitted changes (".dirty"), and -that this commit is two revisions ("+2") beyond the "0.11" tag. For released -software (exactly equal to a known tag), the identifier will only contain the -stripped tag, e.g. "0.11". - -Other styles are available. See details.md in the Versioneer source tree for -descriptions. - -## Debugging - -Versioneer tries to avoid fatal errors: if something goes wrong, it will tend -to return a version of "0+unknown". To investigate the problem, run `setup.py -version`, which will run the version-lookup code in a verbose mode, and will -display the full contents of `get_versions()` (including the `error` string, -which may help identify what went wrong). - -## Updating Versioneer - -To upgrade your project to a new release of Versioneer, do the following: - -* install the new Versioneer (`pip install -U versioneer` or equivalent) -* edit `setup.cfg`, if necessary, to include any new configuration settings -  indicated by the release notes -* re-run `versioneer install` in your source tree, to replace -  `SRC/_version.py` -* commit any changed files - -### Upgrading to 0.16 - -Nothing special. - -### Upgrading to 0.15 - -Starting with this version, Versioneer is configured with a `[versioneer]` -section in your `setup.cfg` file. Earlier versions required the `setup.py` to -set attributes on the `versioneer` module immediately after import. The new -version will refuse to run (raising an exception during import) until you -have provided the necessary `setup.cfg` section. - -In addition, the Versioneer package provides an executable named -`versioneer`, and the installation process is driven by running `versioneer -install`. In 0.14 and earlier, the executable was named -`versioneer-installer` and was run without an argument. - -### Upgrading to 0.14 - -0.14 changes the format of the version string. 0.13 and earlier used -hyphen-separated strings like "0.11-2-g1076c97-dirty". 0.14 and beyond use a -plus-separated "local version" section strings, with dot-separated -components, like "0.11+2.g1076c97". PEP440-strict tools did not like the old -format, but should be ok with the new one. - -### Upgrading from 0.11 to 0.12 - -Nothing special. - -### Upgrading from 0.10 to 0.11 - -You must add a `versioneer.VCS = "git"` to your `setup.py` before re-running -`setup.py setup_versioneer`. This will enable the use of additional -version-control systems (SVN, etc) in the future. - -## Future Directions - -This tool is designed to make it easily extended to other version-control -systems: all VCS-specific components are in separate directories like -src/git/ . The top-level `versioneer.py` script is assembled from these -components by running make-versioneer.py . In the future, make-versioneer.py -will take a VCS name as an argument, and will construct a version of -`versioneer.py` that is specific to the given VCS. It might also take the -configuration arguments that are currently provided manually during -installation by editing setup.py . Alternatively, it might go the other -direction and include code from all supported VCS systems, reducing the -number of intermediate scripts. - - -## License - -To make Versioneer easier to embed, all its code is dedicated to the public -domain.
