Ruby version of preg_match_all?

I’m having a hard time finding a way of archiving the functionality of
PHP’s preg_match_all[1] in Ruby. Am I just not looking in the right
places? I have a string like “SomethingCool SomethingWild Something
AnotherCool” and want to use a regular expression, like /(\w+Cool)/, to
get all the *Cool words back in an array ([“SomethingCool”,
“AnotherCool”]).

I guess String#scan will do it:

  "SomethingCool SomethingWild".scan(/(\w+Cool)/)

Regards,

Try String#scan:

“SomethingCool SomethingWild Something AnotherCool”.scan(/\b(\S+Cool)\b/)

Hi,

I’m having a hard time finding a way of archiving the functionality of
PHP’s preg_match_all[1] in Ruby. Am I just not looking in the right
places? I have a string like “SomethingCool SomethingWild Something
AnotherCool” and want to use a regular expression, like /(\w+Cool)/, to

String#scan might be what you’re looking for:

“cool wild anothercool”.scan(/\b\w*cool\b/)
[“cool”, “anothercool”]

Hope this helps,

Bill
