versionbump (GitHub) is a Python library and utility for bumping version number of semantic versioning (SemVer).
You tells it what the current version is, then it will search for that in a list of files to bump the number:
$ versionbump -c 1.0.0 minor setup.py 1.1.0
You could bump major, minor, and patch. If you don’t give at least one file, it simply echoes out the bumped version, for example:
$ versionbump -c 1.1.0 major 2.0.0
If it can’t find the current version number in files to bump, then it will raise an error, so the user can investigate:
$ versionbump -c 3.4.5 patch setup.py [snip] ValueError: Version not in file.
You can also use it as library for programmatic interface via versionbump.VersionBump and versionbump.FileBump.
For examples, from its README:
from versionbump import VersionBump vb = VersionBump('2.0.1') vb.bump() ## default value: 'patch' print vb.get() ## 2.0.2 print vb.get('patch') ## 2 from versionbump import FileBump fo = open('version.txt', 'r+') fb = FileBump(fo, '2.0.1') vb.bump() ## default value: 'patch', writes to file print vb.get() ## 2.0.2 print vb.get('patch') ## 2
versionbump is written by Fabian Kochem under the MIT License, currently version 1.0.0 (2014-04-05). There is also an alternative bumpversion by Filip Noetzel, which is more configurable and can work with VCS, doing tasks like committing and creating tag for you.
