Subject: [ruby-core:46806] [ruby-trunk - Feature #6802] String#scan should have equivalent yielding MatchData


Issue #6802 has been updated by Eregon (Benoit Daloze).


=begin
You can use (({String#scan})) with the block form and (({$~})) (as well as other Regexp-related globals) for this:

    > text="x:1 y:12 ; x:33 y:2"
    > text.scan(/x:(?<x>\d+) y:(?<y>\d+)/) { p [$~[:x],$~[:y]] }
    ["1", "12"]
    ["33", "2"]

Please check your Regexp and give an example of (({text})) next time.

Feature #6802: String#scan should have equivalent yielding MatchData

Ruby should have method to obtain not an array of arrays but of MatchData objects. It can help in obtaining named groups:

pattern = /x: (?<x>\d+) y:(?<y>\d+)/
polygon = []
text.scan_for_pattern(pattern){|m| polygon << Point.new(m[:x], m[:y]) }

Not to break existing code we need unique name. Ideas? May be #each_match
