is there a ruby one-line “return if x”?

Question

have a ton of places I need to add

if this_flag
  return
end

can that be done on one line with ruby?

Answer 1

Some additions to Jörg W Mittag's good answer:

x && return
x and return
if x then return end

I do not actually recommend the first two forms: however, the above examples are all valid productions. I personally prefer to avoid return in general -- most grammar constructs in Ruby are usable expressions.

Happy coding.
