The following (still strictly experimental) version of automatic
help-echo display eliminates the main obnoxiousness of the original
version. In the original version, you could be asked a question in
the minibuffer, have to think about the answer, and suddenly the
question disappears for some useless help-echo. The following version
prevents that. It will only display the help-echo if the minibuffer
is empty or contains "Quit". So, if you have "Mark set" in the echo
area, you have to do C-g or otherwise clear the echo area (say by
moving point) to get the help-echo. Seems better than to miss an
important message, if not paying attention, by having it overridden by
help-echo. Anyway, I wound up finding the original version unbearable
in actual use. I found the one below much better.
===File ~/newhelp-timer.el==================================
(defun print-local-help (&optional timer)
"Display help related text or overlay properties.
This displays a short help message in the echo area, namely the
value of the `short-help' text or overlay property at point. If
there is no `short-help' property at point, but there is a
`help-echo' property whose value is a string, then that is
printed instead.
The timer argument is meant for use in `run-with-idle-timer' and
prevents display of a message in case there is no help."
(interactive)
(let ((short (get-char-property (point) 'short-help))
(echo (get-char-property (point) 'help-echo)))
(cond (short (message "%s" short))
((stringp echo) (message "%s" echo))
((not timer) (message "No local help at point")))))
(defvar delay 1)
(defvar local-help-timer nil)
(unless local-help-timer
(setq local-help-timer
(run-with-idle-timer delay t #'maybe-display-help)))
(defun maybe-display-help ()
(unless (and (current-message)
(not (string= (current-message) "Quit")))
(print-local-help t)))
(defun cancel-echo ()
(interactive)
(cancel-timer local-help-timer)
(setq local-help-timer nil))
(global-set-key "\C-h\C-l" 'print-local-help)
