Catch all exceptions in your Ruby program

Just put your code between begin and rescue statements and print the error. An example:


ree-1.8.7-head :010 > begin
ree-1.8.7-head :011 > Testing.new
ree-1.8.7-head :012?> rescue Exception => msg
ree-1.8.7-head :013?> puts "Something went wrong ("+msg+")"
ree-1.8.7-head :014?> end
Something went wrong (uninitialized constant Testing)
=> nil

You can boot your application between begin and rescue and you will be able to print the error, perform an action, send an email in the rescue begin section:

begin
 MyApp.run!
rescue Exception => msg
 puts "Something went wrong ("+msg+")"
end
