Usage

This module provides just couple of functions, main of which are:

.. code-block:: python

>>> import semver
>>> semver.compare("1.0.0", "2.0.0")
-1
>>> semver.compare("2.0.0", "1.0.0")
1
>>> semver.compare("2.0.0", "2.0.0")
0
>>> semver.match("2.0.0", ">=1.0.0")
True
>>> semver.match("1.0.0", ">1.0.0")
False
>>> semver.format_version(3, 4, 5, 'pre.2', 'build.4')
'3.4.5-pre.2+build.4'
>>> version_parts = semver.parse("3.4.5-pre.2+build.4")
>>> version_parts == {
...     'major': 3, 'minor': 4, 'patch': 5,
...     'prerelease': 'pre.2', 'build': 'build.4'}
True
>>> version_info = semver.parse_version_info("3.4.5-pre.2+build.4")
>>> version_info
VersionInfo(major=3, minor=4, patch=5, prerelease='pre.2', build='build.4')
>>> version_info.major
3
>>> version_info > (1, 0)
True
>>> version_info < (3, 5)
True
>>> semver.bump_major("3.4.5")
'4.0.0'
>>> semver.bump_minor("3.4.5")
'3.5.0'
>>> semver.bump_patch("3.4.5")
'3.4.6'
>>> semver.max_ver("1.0.0", "2.0.0")
'2.0.0'
>>> semver.min_ver("1.0.0", "2.0.0")
'1.0.0'

Installation

For Python 2:

.. code-block:: bash

pip install semver

For Python 3:

.. code-block:: bash

pip3 install semver

How to Contribute

When you make changes to the code please run the tests before pushing your code to your fork and opening a pull request_:

.. code-block:: bash

python setup.py test

We use py.test_ and tox_ to run tests against all supported Python versions. All test dependencies are resolved automatically, apart from virtualenv, which for the moment you still may have to install manually:

.. code-block:: bash

pip install "virtualenv<14.0.0"  # <14.0.0 needed for Python 3.2 only

You can use the clean command to remove build and test files and folders:

.. code-block:: bash

python setup.py clean
