Hi List,
is there any way to make Emacs print "^J" instead of "\n" with
(print-escape-newlines t)?
If not, how can I replace the newlines in a string with the string "^J"?

cheers,

Ok, forget the second part of the question, thats easy ... I forgot
somehow.
But I would still be interested in the first part.

I think you would need to modify the following part of src/print.c:
if (c == '\n' && print_escape_newlines)
{
PRINTCHAR ('\\');
PRINTCHAR ('n');
}
(not sure how to tell PRINTCHAR to print ^J) and recompile Emacs.

I see, although thats probably a bit too low-level for me. But thanks
for the hint, it motivated me to finally download the Emacs sources, the
C code seems to be quite readable - even when not knowing much about C
at all.
