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.
