Question

Is there a way to decorate a function in Ruby as it’s done in Python? That is, have something execute at the beginning (and end?) of each function.

Answer 1

If by function you mean closure, you could use a block:

def foo
  puts 'before code'

  yield

  puts 'after code'
end

foo { puts 'here is the code' }
