This file helps distutils-based projects manage their version number by just
|
|
creating version-control tags.
|
|
|
|
For developers who work from a VCS-generated tree (e.g. 'git clone' etc),
|
|
each 'setup.py version', 'setup.py build', 'setup.py sdist' will compute a
|
|
version number by asking your version-control tool about the current
|
|
checkout. The version number will be written into a generated _version.py
|
|
file of your choosing, where it can be included by your __init__.py
|
|
|
|
For users who work from a VCS-generated tarball (e.g. 'git archive'), it will
|
|
compute a version number by looking at the name of the directory created when
|
|
te tarball is unpacked. This conventionally includes both the name of the
|
|
project and a version number.
|
|
|
|
For users who work from a tarball built by 'setup.py sdist', it will get a
|
|
version number from a previously-generated _version.py file.
|
|
|
|
As a result, loading code directly from the source tree will not result in a
|
|
real version. If you want real versions from VCS trees (where you frequently
|
|
update from the upstream repository, or do new development), you will need to
|
|
do a 'setup.py version' after each update, and load code from the build/
|
|
directory.
|
|
|
|
You need to provide this code with a few configuration values:
|
|
|
|
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. 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
|
|
update_files' 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.
|
|
|
|
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'.
|
|
|
|
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.
|
|
|
|
parentdir_prefix: a 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 use it:
|
|
|
|
1: include this file in the top level of your project
|
|
2: make the following changes to the top of your setup.py:
|
|
import versioneer
|
|
versioneer.versionfile_source = 'src/myproject/_version.py'
|
|
versioneer.versionfile_build = 'myproject/_version.py'
|
|
versioneer.tag_prefix = '' # tags are like 1.2.0
|
|
versioneer.parentdir_prefix = 'myproject-' # dirname like 'myproject-1.2.0'
|
|
3: add the following arguments to the setup() call in your setup.py:
|
|
version=versioneer.get_version(),
|
|
cmdclass=versioneer.get_cmdclass(),
|
|
4: run 'setup.py update_files', which will create _version.py, and will
|
|
append the following to your __init__.py:
|
|
from _version import __version__
|
|
5: modify your MANIFEST.in to include versioneer.py
|
|
6: add both versioneer.py and the generated _version.py to your VCS
