Rack::Olark

Middleware which inserts Olark JavaScript embed code before in HTML served by Rack.

In config.ru, or wherever else you mount middleware:

use Rack::Olark, id: '1234-567-89-0123'

All non-special options given to Rack::Olark are passed through as JavaScript in the following manner:

olark.configure('key', value);

There are two special options: id and paths.

id is your Olark Site-ID, and the middleware won't allow your app to boot without it.

paths decides which of your routes will display the Olark chat box. It accepts an array of routes, with the leading slash (/) included. paths defaults to empty array ([]), causing Olark to be embedded for every route. As of version 0.0.4, routes in paths can also be described with a Regexp. Non-Regexp paths entries will be handled using:

/^#{Regexp.escape('/my/path')}$/

Example of usage with options:

use Rack::Olark, {
  :id                          => '1234-567-89-0123',
  :paths                       => ['/', '/aboutus'],
  'features.attention_grabber' => true,
}

Note that in order to use custom Olark JavaScript options, you may have to revert to hashrocket syntax, as they tend to contain characters Ruby doesn't like in symbols.
