Global rescue and logging exceptions in Sinatra

How do I specify a global rescue in case of an exception, and if you use Sinatra for an API or application, how do you handle logging?

I had trouble getting this working out of the box in my dev environment - to get it to work, I had to set show_exceptions to false in my sinatra config. 

class BaseApp < Sinatra::Base

  configure { set :show_exceptions, false }

  error do |err|
    raise "Error: #{err}"
  end

end

This setting, when set to true, enables error pages that show backtrace and environment information when an unhanded exception occurs, but I could only fire custom errors by disabling it.

404s can be handled with the help of the not_found method like eg:

not_found do
  'Site does not exist.'
end

500s can be handled by calling the error method with a block, eg:

error do
  "Application error. Pls try later."
end

The details of the error can be accessed via the sinatra.error in request.env like so:

error do
  'An error occured: ' + request.env['sinatra.error'].message
end
