Which Browser

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.
