Hi
I've created an ordered collection of strings. I'd like to paste each element of the ordered collection together into one long string that contains all of the elements of the ordered collection.
So given this: | col | col := OrderedCollection with: 'asdf' with: '1234' with: 'aaaa'.
I'd like to end up with this:
'asdf1234aaaa'
I've come up with this: | col | col := OrderedCollection with: 'asdf' with: '1234' with: 'aaaa'. String streamContents: [:stream | col do: [:i | stream print: i]]
but that gives: '''asdf''''1234''''aaaa'''
What else should I do? Thanks
Paul
Try output := col inject: '' into: [:a :b | a,b].
And check out the terse guide to Squeak:
http://wiki.squeak.org/squeak/5699.
I can never remember the format for inject, but got it right somehow this time!

Use nextPutAll: instead of print:.

You could use the SplitJoin package.
http://www.squeaksource.com/SplitJoin.html
'' join: (OrderedCollection with: 'asdf' with: '1234' with: 'aaaa') --
'asdf1234aaaa'
