Quickstart
==========

.. teaser-begin

A Python module for `semantic versioning`_. Simplifies comparing versions.

.. teaser-end

.. note::

This project works for Python 3.7 and greater only. If you are
   looking for a compatible version for Python 2, use the
   maintenance branch |MAINT|_.

The last version of semver which supports Python 2.7 to 3.5 will be
   2.x.y However, keep in mind, the major 2 release is frozen: no new
   features nor backports will be integrated.

We recommend to upgrade your workflow to Python 3 to gain support,
   bugfixes, and new features.

.. |MAINT| replace:: ``maint/v2``
.. _MAINT: https://github.com/python-semver/python-semver/tree/maint/v2

The module follows the ``MAJOR.MINOR.PATCH`` style:

* ``MAJOR`` version when you make incompatible API changes,
* ``MINOR`` version when you add functionality in a backwards compatible manner, and
* ``PATCH`` version when you make backwards compatible bug fixes.

Additional labels for pre-release and build metadata are supported.

To import this library, use:

.. code-block:: python

>>> import semver

Working with the library is quite straightforward. To turn a version string into the
different parts, use the ``semver.Version.parse`` function:

.. code-block:: python

>>> ver = semver.Version.parse('1.2.3-pre.2+build.4')
    >>> ver.major
    1
    >>> ver.minor
    2
    >>> ver.patch
    3
    >>> ver.prerelease
    'pre.2'
    >>> ver.build
    'build.4'

To raise parts of a version, there are a couple of functions available for
you. The function ``semver.Version.bump_major`` leaves the original object untouched, but
returns a new ``semver.Version`` instance with the raised major part:

.. code-block:: python

>>> ver = semver.Version.parse("3.4.5")
    >>> ver.bump_major()
    Version(major=4, minor=0, patch=0, prerelease=None, build=None)

It is allowed to concatenate different "bump functions":

.. code-block:: python

>>> ver.bump_major().bump_minor()
    Version(major=4, minor=1, patch=0, prerelease=None, build=None)

To compare two versions, semver provides the ``semver.compare`` function.
The return value indicates the relationship between the first and second
version:

.. code-block:: python

>>> 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

There are other functions to discover. Read on!
