Question

Does anybody know what’s the newline delimiter for a string in smalltalk?

I’m trying to split a string in separate lines, but I cannot figure out what’s the newline character in smalltalk.

ie.

string := 'smalltalk is 
           a lot of fun.
           ok, it's not.'

I need to split it in:
line1: smalltalk is
line2: a lot of fun.
line3: ok, it's not.

I can split a line based on any letter or symbol, but I can’t figure out what the newline delimter is.

OK here is how I’m splitting the string based on commas, but I cannot do it based on a new line.

Answer 1

The newline delimiter is typically the carriage return, i.e., Character cr, or as others mentioned, in a string, String cr. If you wanted to support all standard newline formats, just include both standard delimiters, for example:

string := 'smalltalk is
a lot of fun.'.

string findTokens: String cr, String lf.

Since you now mention you’re using VisualWorks, the above won’t work unless you have the “squeak-accessing” category loaded (which you probably won’t unless you’re using Seaside). You could use a regular expression match instead:

'foo
bar' allRegexMatches: '[^', (String with: Character cr), ']+'
