Ruby: regex scanning in a case statement

22 May 2012

Here’s a handy ruby snippet that might come in handy one day.

When the regex matches (input should end with “ today”), you can directly grab the matched value using the special $1 variable.

case input
when /(.*)\stoday$/i then
  puts "Today: #{$1}"
end

I think you can see how you can bend this to your own needs.
