Thank you for your suggestion. They both however breaks up words.
if the text is
"hello how are you today" and the width is set to 6, I want it to become
"hello how are you today"
and not
"hello how ar e you t oday"
Sorry...

Ok, that was what I thought initially. In that case however, I think that sprintf("%/-*s", length, s) will do. Maybe (s / length)*"\n"+"\n" is the simpler approach then.

Adding as well as removing spaces is not desired. The string must remain unchanged other than it having newlines inserted, so
"1 2 3 4" converted to a col width of 1 would become exactly the same as
"1\n \n2\n \n3\n \n4\n"
Does this answer your question?

I am still not quite sure right now what kind of behaviour you would like to have. Please tell me if I got it right: You want no skipping of spaces _but_ linebreaks between words? So adding spaces is ok but skipping is bad?
I am asking because your initial example was different (fixed field size much smaller than words, etc).

What if I _want_ my text to indent? Now it's not possible (not

I could write my own function, but I still think it's faulty

end up at the beginning od a line must be removed because the
line
must start with text. otherwise the line would be indented.

without
removing spaces where linebreaks are introduced.
