Schmobile

A mobile user agent detection Rack middleware. It provides Rack::Request#is_mobile?

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:

Schmobile::UserAgents.add_user_agent_pattern("wibble")
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 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 Schmobile, :redirect_to => "/mobile"

It supports string interpolation for dynamic destinations:

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