[ruby-dev:44851] [ruby-trunk - Feature #5606] String#each_match(regexp)

ruby-dev #44851
Issue #5606 has been updated by Yui NARUSE.
String#scan ではダメな理由を、ユースケースを添えて示す必要があると思います。
----------------------------------------
Feature #5606: String#each_match(regexp)
http://redmine.ruby-lang.org/issues/5606
Author: Tomoaki Nishiyama
Status: Open
Priority: Low

Category:
Target version:
文字列上の正規表現に一致する場所のoffsetを順に処理できるような
イテレータが欲しかったのですが、
ざっと検索すると1996年
http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-list/1206
の昔から話はあり、
http://stackoverflow.com/questions/6804557/how-do-i-get-the-match-data-for-all-occurrences-of-a-ruby-regular-expression-in
全くないという事はなくて、それなりに需要がありそうです。
class String
def each_match(pattern, offset=0)
while(m = self.match(pattern, offset))
offset = m.begin(0)+1
yield m
end
end
end
いかがしょうか？
対称にはRegexp#each_matchもですが、、
