Related to the read-onliness of the IELM prompt:
M-x ielm =>
* Welcome to IELM *** Type (describe-mode) for help.
ELISP>
C-c C-c =>
Process ielm interrupt
M-x ielm =>
*** Welcome to IELM *** Type (describe-mode) for help.
with no prompt, and a message: "Text is read-only".
A way to fix it is with the attached patch, which:
- wraps the insertion of the header on a
(let ((inhibit-read-only t))
...)
- adds a call to (goto-char (point-max)) at the end of `ielm',
because, as it stands, `inferior-emacs-lisp-mode' can not change the
point when invoked from inside the *ielm* buffer (as happens while
restarting the ielm process).
Personally, I think it'd be better to just do
(when (= (point-min) (point-max))
;; Add a silly header
(insert ielm-header)
...)
and *not* insert the header when restarting the process, just when the
*ielm* buffer is created the first time around.
Opinions?
