Question

I have a long string formatted like a log entry and am looking to get several captures from it and store them in different variables.

I know Ruby stores the first 9 captures into the variables $1…$9, does it also store other captures in $10…$99?

If not what would be a simple way to do this?

Answer 1

Yes, it does.

"a2c4d7l4l0j4h9h7".gsub(/(\w)(\d)(\w)(\d)(\w)(\d)(\w)(\d)(\w)(\d)(\w)(\d)(\w)(\d)(\w)(\d)/) do
  $12
end
#=> "4"
