Re: [Pharo-users] can I do this with a stream or a format

Maybe this is a better way to build what you want. String streamContents: [:stream | gifts do: [:each | stream nextPutAll: each ] separatedBy: [ stream nextPut: $,; space ] ] Esteban A. Maringolo On Thu, May 16, 2019 at 4:21 PM Roelof Wobben <r.wobben@home.nl> wrote:

Hello,

Im testing all my solutions with critiz and can solve almost all problems,

Only this one I cannot figure out.

I have this code

(gifts allButLast inject: '' into: [ :str :each | str , each , ', ' ]) , 'and ' , gifts last ]

and critiz says I should use a stream .

How can I make this work ?
