schmobile

A mobile user agent detection Rack middleware. It does this by providing #is_mobile? to Rack::Request

Forcing mobile mode

You can force toggle mobile mode by sending is_mobile=true and is_mobile=false as parameters in the request URL. This setting will be stored in the session for subsequent requests. This entirely overrides the user agent detection.

User agent detection

You can add/remove user agents like so:

Rack::Schmobile::UserAgents.add_user_agent_pattern("wibble")
Rack::Schmobile::UserAgents.remove_user_agent_pattern("ipad")

Filters

The outcome of the request.is_mobile? call is the product of a series of filters getting evaluated against the request. You can manipulate the Rack::Schmobile::Filters::CHAIN array to alter if a request is deemed mobile or not. Add your own filter to bypass the check depending on e.g. location or request format.

Redirecting

It can be configured to return the user to an explicit destination:

use Rack::Schmobile, :redirect_to => "/mobile"

It supports string interpolation for dynamic destinations:

use Rack::Schmobile, :redirect_to => "/mobile/#!/{{path}}"

Finally the middleware provides a request level method to determine if the client is a mobile device

Rack::Request#is_mobile?

Rolling out

use Rack::Schmobile, :redirect_to => "/mobile", :if => Proc.new { |request| request.host =~ /staging/ }

Check out the latest master to make sure the feature hasn’t been implemented or the bug hasn’t been fixed yet
Check out the issue tracker to make sure someone already hasn’t requested it and/or contributed it
Fork the project
Start a feature/bugfix branch
Commit and push until you are happy with your contribution
Make sure to add tests for it. This is important so I don’t break it in a future version unintentionally.
Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
