Hello,

I wonder if it is possible in Pharo to divide a string in lets say part of 3. so this : 'abcdefgh'

would be 'abc def gh`

Do you really want a single string with spaces inserted or do you want a collection of substrings, each three characters (or less, for the last one)?

I need a single string with spaces inserted. So maybe I have formulate my question wrong. Very difficult if English is not your mother language and you were bad at school in languages a very very long ago.

I didn't previously know of a method to do this, but I "guessed" what you needed might be related to "grouping", so I did... 'abcd' inspect. then in the Meta tab, starting at Collection, filtered on.... group* and worked up the hierarchy discovering #groupsOf:atATimeDo: in SequenceableCollection, which guesswork found could work like this... ``` input := 'abcdefghijk'. stream := String streamContents: [:s | input groupsOf: 3 atATimeDo: [ :group | s nextPutAll: group; nextPutAll: ' ']]. stream contents inspect. ``` One of the skills a new programmer needs to develop is to make those educated "guesses" and know where/how to test them. So I learnt a new method today. thx. cheers -ben
