Using versiontools is very easy. Just follow those steps to do it.
Put this code your package’s __init__.py or in your main module:
__version__ = (1, 2, 3, 'final', 0) # replace with your project version
You will need to keep a copy of versiontools_support.py file in your source tree. This file will be needed by your users that don’t have versiontools to still be able to run setup.py to install your package.
You will need to update (or create) MANIFEST.in to ensure that each source distribution you make with setup.py sdist will ship a copy of the support file. All that you have to do is to append this line to your MANIFEST.in:
include versiontools_support.py
Edit your setup.py to have code that looks like this:
import versiontools_support
setup(
version = ":versiontools:your_package",
)
The trick here is to use a magic value for version keyword. The format of that magic value is:
":versiontools:" - a magic string that versiontools matches
your_package - name of your package or module to import
":" - colon separating package from identifier (optional)
identifier - Object to import from your_package. (optional)
Can be omitted if equal to __version__.
This will make versiontools use versiontools.format_version() on whatever your_package.__version__ contains. Since your __version__ is a tuple as described above you’ll get a correctly formatted version identifier.
This code will ensure that:
While you are working on the next version of your project you should make sure that releaselevel is set to "dev". This will (if you have proper vcs integration in place) allow you to get the most benefit.
Each time you make a release (with setup.py sdist or any bdist commands) make sure to change the releaselevel to something other than "dev". You can use the following strings:
