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 -import os, sys, re -from distutils.core import Command -from distutils.command.sdist import sdist as _sdist -from distutils.command.build import build as _build +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. -versionfile_source = None -versionfile_build = None -tag_prefix = None -parentdir_prefix = None +### Upgrading from 0.11 to 0.12 -VCS = "git" -IN_LONG_VERSION_PY = False +Nothing special. +### Upgrading from 0.10 to 0.11 -LONG_VERSION_PY = ''' -IN_LONG_VERSION_PY = True +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.
