UAParser

A user-agent parser for Erlang, based on the process used by ferd's useragent. Currently, this library supports:

• Browser Identification
  • MSIE, Firefox, Chrome, Opera, and many others
  • Version identification for a majority of support browsers
• Operating System Identification
  • Windows, Mac OS X, Android, IOS, "Linux", WebOS, and others.
  • Version Identification for the following:
    • Windows
    • Android
    • WebOS
    • iOS
    • Mac OS X

The process used has proven to be significantly more efficient than libraries which rely upon long lists of regular expressions, all the while losing little with respect to accuracy.

Usage

Simply call the function uaparser:parse/1 with the user-agent as its argument, as follows:

Erlang R16B03 (erts-5.10.4) [source] [64-bit] [smp:4:4] [async-threads:10] [hipe] [kernel-poll:false]

Eshell V5.10.4  (abort with ^G)
1> uaparser:parse("Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; Trident/5.0; SLCC1; .NET CLR 2.0.50727; InfoPath.1; .NET CLR 3.5.30729; WinTSI 08.02.2010; .NET CLR 3.0.30729; .NET4.0C; BRI/1)").
[{browser,[{name,<<"internet explorer 7">>},
           {family,ie},
           {manufacturer,microsoft},
           {type,web_browser},
           {renderer,trident},
           {version,<<"7.0">>},
           {version_details,[{major,7},{minor,0}]}]},
 {os,[{name,<<"windows vista">>},
      {family,windows},
      {manufacturer,microsoft},
      {type,computer},
      {version,<<"6.0">>},
      {version_details,[{major,6},{minor,0}]}]}]

You will receive nested proplists back containing extracted information on both the browser and the operating system.
