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'
>>> 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
