Hello, I brought up the topic of adding the DOTALL modifier to the Chrome V8 Engine here <https://groups.google.com/a/chromium.org/forum/#!topic/chromium-discuss/K9h0qB3Z3Gw> and was directed to es-discuss. I was curious about the practicality and the want for adding a DOTALL modifier to the ECMAScript standards in the future?
For those that don't know that DOTALL modifier is a regex modifier that allows the '.' symbol to match newlines as well. *Example regex:* /he[.*]?llo/ *Example search string 1: *hello *Example search string 2: *he llo The above regex will match the 1st search string but will not match the 2nd. In ECMAScript the only current way to make a match like that work is to use [\d\D] which will match everything including newlines, given below. *Current workaround regex: */he[\d\D]?llo/ The *s* modifier is the standard in most major languages except Javascript and Ruby. This will allow newline matching for the . symbol. The proposed regex is below: *Proposed new regex: */he[.*]?llo/s *Example search string: *he llo Let me know if there is any more information I can provide, or any questions you have. Thanks much, Jake
