I'd like to match a regex and get the position in the string of the match
For example,
"AustinTexasDallasTexas".match_with_posn /(Texas)/
I'd like match_with_posn
to return something like: [6, 17]
where 6 and 17 are the start positions for both instances of the word Texas.
Is there anything like this?
Using Ruby 1.8.6+, you can do this:
require 'enumerator' #Only for 1.8.6, newer versions should not need this.
s = "AustinTexasDallasTexas"
positions = s.enum_for(:scan, /Texas/).map { Regexp.last_match.begin(0) }
This will create an array with:
=> [6, 17]
