merb_hoptoad_notifier
---------------------------------------------
This is merb plugin for exception notification with hoptoad. It should work with
any merb app that's based on merb 1.0 and higher
This plugin: https://github.com/atmos/merb_hoptoad_notifier/tree/master
The original: https://github.com/thoughtbot/hoptoad_notifier/tree/master
NOTE: I don't maintain this anymore, if you want exception notification in merb
please try out the rack plugin, https://github.com/atmos/rack_hoptoad
Usage:
1) Get your api key for your app from hoptoadapp.com
2) Add the api key to config/hoptoad.yml with a similar syntax as the following
---
:development: &defaults
  :api_key: ZOMGLOLROFLMAO
:rake:
  <<: *defaults
:test:
  <<: *defaults
:production:
  :api_key: UBERSECRETSHIT
3) Require hoptoad in init.rb
require 'merb_hoptoad_notifier'
4) Add the following method to your Exceptions controller.  Depending on your merb version you'll need to use the 
exceptions,standard_error, or internal_server error as the action name.  Kinda weak, but the API changed a lot in 0.9.x
class Exceptions < Merb::Controller
  if %w( staging production ).include?(Merb.env)
    def standard_error
      HoptoadNotifier.notify_hoptoad(request, session)
      render
    end
  end
end
5) Restart the server, trigger an error(in staging or prod) and check that it arrived at hoptoad :)
Filtersing your post environment
--------------------------------
If you have environmental variables set in your ruby process that should not be sent to hoptoad,
there's a mechanism for filtering those attributes now.  Throw something like this in 
config/init.rb
Merb::BootLoader.after_app_loads do
  HoptoadNotifier.environment_filters = %w(^AWS ^EC2 SECRET PRIVATE KEY)
end
Each of these words will be compiled into a regex so you should be able to use anchors if needed.
