multi line text in the margins

multi line text in the margins

[cage]

Hi!

I am exploring the margin feature of Emacs. I tried to write some text
with a line break character inside, adding a text property like that:

(list :display (list '(margin margin-right) "foo\nbar"))


But the line break character is printed as "^J" instead to be interpreted.

Now i wonder if there is a way to split text in lines on the margin.

Any idea?

Thanks in advance!
C.

You can't.  This is not supported (and will cause complications if we
did try supporting it, because margin text of line N could get in the
way of margin text of lines N+1, N+2, ...

Thanks for you answer, I think  you even anticipated my next question:
if would be possible to make Emacs fits text between the margin's ends
(something like visual-line-mode). ;-D
