With Emacs 27.2, I want to generate a list of stuff with em-
bedded Emacs Lisp scripts to work on it. The Emacs Lisp
scripts have newlines as string literals in them.
When I evaluate:
| #+BEGIN_SRC elisp :results raw :var number-of-lines=1
| (mapconcat
| (lambda (i)
| (concat
| (org-link-make-string (concat "elisp:" (prin1-to-string `(message "Hello, World %d!\n" ,i))) (format "Test #1.%d" i))
| "\n"))
| (number-sequence 1 number-of-lines)
| "")
| #+END_SRC
for the first time with C-c C-c, I get:
| #+RESULTS:
| [[elisp:(message "Hello, World %d!
| " 1)][Test #1.1]]
which, if shown in org-mode, is and works exactly correct.
(When I rerun C-C C-c, I get:
| #+RESULTS:
| [[elisp:(message "Hello, World %d!
| " 1)][Test #1.1]]
| " 1)][Test #1.1]]
which is not correct, but does not bother me much.)
When I evalute:
| #+BEGIN_SRC elisp :results raw :var number-of-lines=10
| (mapconcat
| (lambda (i)
| (concat
| (org-link-make-string (concat "elisp:" (prin1-to-string `(message "Hello, World %d!\n" ,i))) (format "Test #1.%d" i))
| "\n"))
| (number-sequence 1 number-of-lines)
| "")
| #+END_SRC
I get:
| #+RESULTS:
| [[elisp:(message "Hello, World %d!
| " 1)][Test #1.1]]
| [[elisp:(message "Hello, World %d!
| " 2)][Test #1.2]]
| [[elisp:(message "Hello, World %d!
| " 3)][Test #1.3]]
| [[elisp:(message "Hello, World %d!
| " 4)][Test #1.4]]
| [[elisp:(message "Hello, World %d!
| " 5)][Test #1.5]]
| [[elisp:(message "Hello, World %d!
| " 6)][Test #1.6]]
| [[elisp:(message "Hello, World %d!
| " 7)][Test #1.7]]
| [[elisp:(message "Hello, World %d!
| " 8)][Test #1.8]]
| [[elisp:(message "Hello, World %d!
| " 9)][Test #1.9]]
| [[elisp:(message "Hello, World %d!
| " 10)][Test #1.10]]
where the last link ("Test #1.10") is not recognized by
org-mode and not clickable.
My guess is that org-link-make-string should escape new-
lines, but does not, and the org-mode parser is liberal
enough to "fix" some links, but not all.

(Sidenote: The issue can be worked around by replacing "\n"
with (make-string 1 10).)

What if you escape the \n, i.e. \\n?

Then org-mode's display is correct, but the message call
will not output a newline, but a backslash and an "n" :-).
