Browser

Do some browser detection with Ruby. Includes ActionController integration.

Installation

gem install browser

Usage

require "rubygems"
require "browser"

browser = Browser.new(:ua => "some string", :accept_language => "en-us")
browser.safari?
browser.opera?
browser.mobile?
browser.firefox?
browser.ie?
browser.ie6?        # this goes up to 9
browser.capable?    # supports some CSS 3
browser.platform    # return :mac, :windows, :linux or :other
browser.mac?
browser.windows?
browser.linux?
browser.meta        # an array with several attributes
browser.to_s        # the meta info joined by space

See the tests for more examples.

Rails integration

Just add it to the Gemfile or ‘environment.rb`, depending of your Rails version.

gem "browser"         #=> Rails 3
config.gem "browser"  #=> Rails 2

This adds a helper method called ‘browser`, that inspects your current user agent.

<% if browser.ie6? %>
  <p class="disclaimer">Your're running an older IE version. Please update it!</p>
<% end %>
