Usage:

script/plugin install git://github.com/brynary/rack-bug.git

config/environments/development.rb

config.middleware.use "Rack::Bug"

add bookmarklet to browser

open http://RAILS_APP/rack_bug/bookmarklet.html

Notes:

To use rack-bug with hoptoad, you need to stub hoptoad from trying to serialize the environment variables that rack-bug uses like so:

HoptoadNotifier.configure do |config| config.environment_filters << 'rack-bug.*' end
