Stef, In keeping with print==developer, display==user, the idea of the developer representation is to quote the text so that it looks like the literal syntax. At least that is what I have always thought it was about. Does that help? Bill Wilhelm K.

the contained element ) does not make too much sense to me. stef On Jan 16, 2009, at 8:44 PM, Bill Schwab wrote:

Stef,

I suspect that Object Arts would favor #printOn:delimiter:. They would also probably have a #displayOn:delimeter: method. Their approach is that one 'displays' for users and 'prints' for developers; they generally don't much like #as* methods, with the exception of true conversion methods (such as #asOrderedCollection, etc.). #displayOn: is used my morphic, which will cause me some hassles some time soon.

FWIW.

stephane.ducasse@inria.fr 1/16/2009 12:55:53 PM >>> Hi all

I would like to have your point of view on the following: on the class collection there are two methods

asStringOn: aStream delimiter: delimString asStringOn: aStream delimiter: delimString last: lastDelimString

printOn: aStream delimiter: delimString printOn: aStream delimiter: delimString last: lastDelimString

which are nearly doing the same. I suggest to remove the printOn: version

since it prints: '1'', ''2'' & ''3'. while asString '1, 2 & 3'

I do not see any use of the printOn version and there is no sender (except tests that I will remove :).
