[Pharo-users] OrderedCollection get all lines

Hi, I would like to reproduce the grep command in Pharo. To do it I wanted to get the content of a stream and transform it to an OrderedCollection (to use matchesRegex: on it). First of all, is there an easier way to do it? In a second time, is there a method to get the content of a Stream as an OrderedCollection ? (nextLine exists so I could use it to get my OrderedCollection but is there an easier way?)
