:mod:`mozversion` --- Get application information
=================================================

`mozversion <https://github.com/mozilla/mozbase/tree/master/mozversion>`_
provides version information such as the application name and the changesets
that it has been built from. This is commonly used in reporting or for
conditional logic based on the application under test.

Note that mozversion can report the version of remote devices (e.g. Firefox OS)
but it requires the :mod:`mozdevice` dependency in that case. You can require it
along with mozversion by using the extra *device* dependency:

.. code-block:: bash

  pip install mozversion[device]


API Usage
---------

.. automodule:: mozversion
    :members: get_version

Examples
````````

Firefox::

    import mozversion

    version = mozversion.get_version(binary='/path/to/firefox-bin')
    for (key, value) in sorted(version.items()):
        if value:
            print '%s: %s' % (key, value)

Firefox for Android::

    version = mozversion.get_version(binary='path/to/firefox.apk')
    print version['application_changeset'] # gets hg revision of build

FirefoxOS::

    version = mozversion.get_version(sources='path/to/sources.xml', dm_type='adb')
    print version['gaia_changeset'] # gets gaia git revision

Command Line Usage
