UseragentParser is a library to detect useful information contained within the Useragent Header transmitted by modern web clients.

require 'useragent_parser'
ua = UseragentParser.parse('Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_6_4; en-US) AppleWebKit/525.13 (KHTML, like Gecko) Chrome/8.0.552.237 Safari/525.13')

This will return a hash containing the following keys:

family - The browser family v1 - The major browser version v2 - The minor browser version v3 - The patch level of the browser os_family - The operating system os_v1 - The major operating system version os_v2 - The minor operating system version os_v3 - The patch level of the operating system

In the case that the family or os_family is unknown, 'Other' will be returned. The version components will return nil in the case that the respective version level in undetectable.

This is a port of the Python ua-parser library.
