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 `$1` variable.
|
||
|
|
|
||
|
|
:::ruby
|
||
|
|
case input
|
||
|
|
when /(.*)\stoday$/i then
|
||
|
|
puts "Today: #{$1}"
|
||
|
|
end
|
||
|
|
|
||
|
|
I think you can see how you can bend this to your own needs.
