Re: [Pharo-users] how to convert this with a stream

      Hi Roelof

The block [] should be (). What's happening is that the block is being added to outcome which will then print itself out.

Cheers

Hello

Could be , im confused now

I tried this :

outcome
        add: 'Team                           | MP |  W |  D |  L |  P'.
    outcome
        add: [ String
                streamContents: [ :s |
                    TeamStatusSorted
                        do: [ :each |
                            s << each name.
                            s << String cr ] ] ].
    ^ outcome

but  get now a output of the header and then the code.

Hi Roelof
I think you meant
  String streamContents:
and not
  Array streamContents:

Hello,
I have a SortedCollection of teams.
Now I need to convert this to a line like this :
'Allegoric Alaskans             |  1 |  1 |  0 |  0 |  3'
I tried it with this :
outcome := Array
        streamContents: [ :s |
            TeamStatusSorted
                do: [ :each |
                    s << each name.
                    s << String cr ] ].
    ^ outcome
or String streamContents but it will not give me the right answer,
So please some hints how I can make this work.
