Go/Golang package for parsing user agent strings

Package ua.New(userAgent string) function parses browser’s and bot’s user agents strings and determins:

  • User agent name and version (Chrome, Firefox, Googlebot, etc.)
  • Operating system name and version (Windows, Android, iOS etc.)
  • Device type (mobile, desktop, tablet, bot)
  • Device name if available (iPhone, iPad, Huawei VNS-L21)
  • URL provided by the bot (http://www.google.com/bot.html etc.)

Still need some work on detecting Android device names.
