Register handler for unhandled exceptions

Question

Is it possible to define an exception handler for any unhandled exceptions? Wrapping all the code in the begin / rescue / end block seems messy.

Answer 1

How about using at_exit? It should be called even when an exception occurs, and you can write the last exception using $!

Here is an example:

at_exit { puts "Last exception: (#{$!.inspect})" puts "Backtrace: \n#{ $@ }" puts "Exiting..." } puts "my app..." raise "Exception!"
