Python User Agents
==================

``user_agents`` is a Python library that provides an easy way to identify/detect devices like mobile
phones, tablets and their capabilities by parsing (browser/HTTP) user agent strings. The goal is to reliably detect whether:

* User agent is a mobile, tablet or PC based device
* User agent has touch capabilities (has touch screen)

``user_agents`` relies on the excellent `ua-parser <https://github.com/tobie/ua-parser>`_ to do the
actual parsing of the raw user agent string.


Installation
============

.. image:: https://secure.travis-ci.org/selwin/python-user-agents.png

``user-agents`` is hosted on `PyPI <http://pypi.python.org/pypi/user-agents/>`_ and can be installed as such::

    pip install pyyaml ua-parser user-agents

Alternatively, you can also get the latest source code from
`Github`_ and install it manually.

Usage
=====

Various basic information that can help you identify visitors can be accessed `browser`, `device`
and `os` attributes. For example:

.. code-block:: python

    from user_agents import parse

    # iPhone's user agent string
    ua_string = 'Mozilla/5.0 (iPhone; CPU iPhone OS 5_1 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Version/5.1 Mobile/9B179 Safari/7534.48.3'
    user_agent = parse(ua_string)

    # Accessing user agent's browser attributes
    user_agent.browser  # returns Browser(family=u'Mobile Safari', version=(5, 1), version_string='5.1')
    user_agent.browser.family  # returns 'Mobile Safari'
    user_agent.browser.version  # returns (5, 1)
    user_agent.browser.version_string   # returns '5.1'
    
    # Accessing user agent's operating system properties
    user_agent.os  # returns OperatingSystem(family=u'iOS', version=(5, 1), version_string='5.1')
    user_agent.os.family  # returns 'iOS'
    user_agent.os.version  # returns (5, 1)
    user_agent.os.version_string  # returns '5.1'
    
    # Accessing user agent's device properties
    user_agent.device  # returns Device(family=u'iPhone', brand=u'Apple', model=u'iPhone')
    user_agent.device.family  # returns 'iPhone'
    user_agent.device.brand # returns 'Apple'
    user_agent.device.model # returns 'iPhone'

    # Viewing a pretty string version
    str(user_agent) # returns "iPhone / iOS 5.1 / Mobile Safari 5.1"


``user_agents`` also expose a few other more "sophisticated" attributes that are derived from one or
more basic attributes defined above. As for now, these attributes should correctly identify
popular platforms/devices, pull requests to support smaller ones are always welcome.

Currently these attributes are supported:

* ``is_mobile``: whether user agent is identified as a mobile phone (iPhone, Android phones, Blackberry, Windows Phone devices etc)
* ``is_tablet``: whether user agent is identified as a tablet device (iPad, Kindle Fire, Nexus 7 etc)
* ``is_pc``: whether user agent is identified to be running a traditional "desktop" OS (Windows, OS X, Linux)
* ``is_touch_capable``: whether user agent has touch capabilities
* ``is_bot``: whether user agent is a search engine crawler/spider


For example:

.. code-block:: python

    from user_agents import parse

    # Let's start from an old, non touch Blackberry device
    ua_string = 'BlackBerry9700/5.0.0.862 Profile/MIDP-2.1 Configuration/CLDC-1.1 VendorID/331 UNTRUSTED/1.0 3gpp-gba'
    user_agent = parse(ua_string)
    user_agent.is_mobile # returns True
    user_agent.is_tablet # returns False
    user_agent.is_touch_capable # returns False
    user_agent.is_pc # returns False
    user_agent.is_bot # returns False
    str(user_agent) # returns "BlackBerry 9700 / BlackBerry OS 5 / BlackBerry 9700"

    # Now a Samsung Galaxy S3
    ua_string = 'Mozilla/5.0 (Linux; U; Android 4.0.4; en-gb; GT-I9300 Build/IMM76D) AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0 Mobile Safari/534.30'
    user_agent = parse(ua_string)
    user_agent.is_mobile # returns True
    user_agent.is_tablet # returns False
    user_agent.is_touch_capable # returns True
    user_agent.is_pc # returns False
    user_agent.is_bot # returns False
    str(user_agent) # returns "Samsung GT-I9300 / Android 4.0.4 / Android 4.0.4"

    # iPad's user agent string
    ua_string = 'Mozilla/5.0(iPad; U; CPU iPhone OS 3_2 like Mac OS X; en-us) AppleWebKit/531.21.10 (KHTML, like Gecko) Version/4.0.4 Mobile/7B314 Safari/531.21.10'
    user_agent = parse(ua_string)
    user_agent.is_mobile # returns False
    user_agent.is_tablet # returns True
    user_agent.is_touch_capable # returns True
    user_agent.is_pc # returns False
    user_agent.is_bot # returns False
    str(user_agent) # returns "iPad / iOS 3.2 / Mobile Safari 4.0.4"

    # Kindle Fire's user agent string
    ua_string = 'Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_6_3; en-us; Silk/1.1.0-80) AppleWebKit/533.16 (KHTML, like Gecko) Version/5.0 Safari/533.16 Silk-Accelerated=true'
    user_agent = parse(ua_string)
    user_agent.is_mobile # returns False
    user_agent.is_tablet # returns True
    user_agent.is_touch_capable # returns True
    user_agent.is_pc # returns False
    user_agent.is_bot # returns False
    str(user_agent) # returns "Kindle / Android / Amazon Silk 1.1.0-80"

    # Touch capable Windows 8 device
    ua_string = 'Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; Trident/6.0; Touch)'
    user_agent = parse(ua_string)
    user_agent.is_mobile # returns False
    user_agent.is_tablet # returns False
    user_agent.is_touch_capable # returns True
    user_agent.is_pc # returns True
    user_agent.is_bot # returns False
    str(user_agent) # returns "PC / Windows 8 / IE 10"
