Hi all,
I'm trying to get an elisp object (more specifically a list) from the minibuffer, using the function edit-and-eval-command, as documented in
http://www.gnu.org/software/emacs/manual/html_mono/elisp.html#Object-from-Minibuffer
For example say I first evaluate:
(setq wildcard '("*.c" "*.h" "*.v"))
Next I am trying to do something like:
(setq newwildcard (edit-and-eval-command "Enter an expression: " (format "%s" wildcard))
but it does not achieves what I really want, which is to provide as initial argument a valid lisp list [e.g. '("*.c" "*.h" "*.v")] so no error is generated if the user simply hits [Enter]. The above generates double quotes and misses the single quote, which causes the problem.
Can anyone give me some insight to do this properly ?
Many thanks,
David.

Do not pass a string as the COMMAND argument to edit-and-eval-command.
(edit-and-eval-command "Edit and eval: " '(quote ("*.c" "*.h" "*.v")))
or equivalently
(edit-and-eval-command "Edit and eval: " (quote '("*.c" "*.h" "*.v")))
