I'm trying to create a link that takes an elisp expression and evaluates it
in another buffer. Here's what I've come up with
1. C-c C-l
2. choose elisp:
3. In the mini buffer:
Link: elisp:(with-output-to-temp-buffer "scratch" (print 20))
Description: Print 20
Okay, this calls up the scratch buffer and prints out 20. But how would I
call up scratch and, say, change its mode to lisp with
(lisp-interaction-mode)? I can try:
Link: elisp:(with-output-to-temp-buffer "scratch" (eval
'(lisp-interaction-mode)))
but this only seems to change my active org file's org-mode to
lisp-interaction-mode. Not a pretty sight. My Messages says:
Execute "(with-output-to-temp-buffer "scratch" (eval
'(lisp-interaction-mode)))" as elisp? y
(with-output-to-temp-buffer "scratch" (eval '(lisp-interaction-mode))) =>
nil
But of course
[[elisp:(zone)][zone]]
is kinda exciting...
What am I doing wrong?

C-h f:
===
This construct makes buffer BUFNAME empty before running BODY.
It does not make the buffer current for BODY.
Instead it binds `standard-output' to that buffer, so that output
generated with `prin1' and similar functions in BODY goes into
the buffer.
===
Try with-current-buffer.

(eval '(x)) means (x).
