Return_bang 1.0 Released

Ruby
1

return_bang version 1.0 has been released!

return_bang implements non-local exits from methods. Use return_bang to
exit
back to a processing loop from deeply nested code, or just to confound
your
enemies and your friends! What could possibly go wrong?

== Features

  • Implements non-local exits for methods
  • Nestable
  • Named and stack-based exit points, go exactly where you need to be
  • Ignores pesky ensure blocks for when you really, really need to return

== Synopsis

require ‘return_bang/everywhere’

def some_method
deeply_nested
# never reached
end

def deeply_nested
return!
end

return_here do
some_method
end

resumes here

== Install

sudo gem install return_bang

Where is this different from the builtin catch/throw mechanism?

It skips all ensure clauses in the call stack; throw() does not.
