This is a tool for managing a recorded version number in distutils-based
|
|
python projects. 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 0.15
|
|
|
|
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.
