line-feed or carriage-return

I have this method in my old Smalltalk,
and wanted to implement it in Dolphin,
at the class Stream.

nextLine
"Answer a String consisting of the characters of
the receiver up to the next line delimiter
(line-feed or carriage-return line-feed)."
| line |
line := self upTo: Lf.
line size > 0 ifTrue: [
(line at: line size) == Cr
ifTrue: [^line copyFrom: 1 to: line size - 1]].
^line

--> Error: undeclared 'Lf'
is coming

Can you help me,
what line-feed Lf and carriage-return Cr is in Dolphin?

Or is there an equal method for nextline in Dolphin?

Thank you,
Katjana

Katjana,

Use the class side methods in the Character class

Lf == Character lf
Cr == Character cr

Character lf and Character cr.

Sure, it's called nextLine; BTW it is defined in the
ReadStream protocol and it is part with the ANSI
Smalltalk standard. You'll find nextLine in any mayor
Smalltalk implementation.
