Which Browser adds a few helper methods to a rack request so you can write cleaner browser-related logic.
For example, the age old battle against IE 5 & 6 can be handled like so:
stylesheet_link_tag "ie" if request.ie_lt7?
And for a nice browser warning:
- if request.ie6?
IE6 makes the internet suck.
- elsif request.ie5?
You've got to be kidding me.
Or in your rails controller, decide which layout:
render :layout => request.mobile? ? 'mobile' : 'application'
Here's some other popular helpers:
request.ie?
request.ie6?
request.ie_lt6?
request.ie_gte7?
request.mobile?
request.ipad?
request.ipod?
request.iphone?
request.mobile_safari?
request.blackberry?
As usual, just use the gem install command:
(sudo) gem install which_browser
Or add which_browser as a gem in your Gemfile:
gem 'which_browser', '>= 0.2.3'
Then run bundle install
Tests can be run with:
git clone git://github.com/citrus/which_browser.git
cd which_browser
bundle
bundle exec rake
There is also a sinatra app in test/dummy for a demo and real-life testing. Install sinatra (gem install sinatra) if you don't have it, then run:
cd which_browser
ruby test/dummy/app.rb
Now open your browser to http://localhost:4567 and fiddle with your user agent.
