Re: [Newbies] String construction and replacement

No, actually no. But the background to my question (which I didn't mention since it doesn't belong to this list) is that I was dealing with a Seaside issue in which one string's newlines came back with CR+LF (carriage return and line feed) and under other conditions it came back as having LF+LF. I wanted to construct a String for these exact sequences and do the appropriate replacement (that is replace all LF+LF ocurrences for CR+LF). I am very glad that in Smalltalk it's possible to write a string-literal like you did (with a newline in-between). 2009/2/2 Ken G.

Is there something wrong with just doing: string := 'Hello There'. ? Ken G.

To all whom I wrote that I found it strange that there was no class method to construct a String from an array... I was wrong! I debugged Randal's suggestion of using "as: String" and the result that "newFrom: aCollection" is called. So, the solution could also be: string := String newFrom: {$H.$I.Character cr. $T.$H.$E.$R.$E}. Of course, to make it completely portable you could also use two ways that have been suggested: add every character into an OrderedCollection and use that, or use a standard array-literal and manually #put: the carriage-return afterwards.
