Hi Lars,
I commit many mistakes when I type, so I prefer recipes that can be
executed by just typing `C-x C-e' at the right places.
The delay is much longer on emacses with more packages loaded and more
functions defined.
If I try to run `M-x find-eev-quick-intro' by typing
M-x f i n d - e e v - q TAB RET
in an Emacs28 without -Q then the code in `execute-extended-command'
takes 10 seconds to display the message
You can run the command `find-eev-quick-intro' with `M-x -q-i'
and _ONLY THEN_ it shows the temporary buffer that
find-eev-quick-intro produces. You're right about this being
interruptible by typing a key - I didn't know that trick - but I'm
used to only choose what to type in those buffers after seeing their
contents, so I'll have retrain myself to type, say, <down>, on such
delays, and for me it's easier to just execute
(setq extended-command-suggest-shorter nil)
when I start to get bothered by such delays than to retrain myself, so
here's one user - me - and one use case - the one above - in which
this matters... =S
There is a recipe here:
https://lists.gnu.org/archive/html/help-gnu-emacs/2021-10/msg00261.html
its main line (plus something that I will explain soon) is:
(execute-extended-command--shorter "find-eev-quick-intro" "find-eev-qui")
(execute-extended-command--shorter "find-eev-quick-intro" "123456789012")
`execute-extended-command--shorter' only cares about the length of its
second argument, so using "find-eev-qui" in the second argument is
equivalent to using "123456789012".
The discussion about that bug is happening part here and part in
help-gnu-emacs. See:
https://lists.gnu.org/archive/html/help-gnu-emacs/2021-10/msg00280.html
Cheers,
E.
