Please avoid using passive tense as much as possible (in the last
sentence).

Also, I think it's accepted practice to use nil as the value which
disables a periodic feature.

(Not that I understand why this particular message needs to be
customizable.)

Thanks.

Because the messages by cpp.el is so frequent that it often competes
with other useful information. I've added some explanation in the
docstring.

The attachment is a new version.

Yes, but we have lots of similar messages in other places.  A search
for a call to 'message' that displays "SOMETHING...done" turns up more
than 270 hits.  Why is this particular package being singled out?

Also, what useful information does it conceal?  Can you show a use
case where this happens?

> I've added some explanation in the docstring.

That should not be necessary, such explanations should be in comments
and commit log messages.

Thanks.

It was not me who singled out this particular package; it was singled
out before, with the frequency hard coded to be 1 second. I just made it
more flexible and correct a misused plain `message'.

I've never seen how these information can be useful (ideally I would say
concealing all these cpp-progress-message unless some debug option is
turned on), but I'm probably not qualified enough to make such
assertion.

One annoying case is that I've set up to show the syntax error at point,
but the "Parsing...done" message frequently comes in the way before I
can read the message.

I'm okay with accepting this for the master branch, but the patch
needs some more work to fix the following issues:

 . The first line of each doc string should be a complete sentence.
 . The doc string of cpp-progress-message should mention
   cpp-message-min-time-interval.
 . The defcustom you are adding should have a :version tag.
 . The calculation in cpp-progress-message should be fixed to
   calculate the time difference between the current time and the time
   of the previous progress message, and compare that with the value
   of cpp-message-min-time-interval.  The old code just looked at the
   2nd member of the list returned by current-time, but that is no
   longer TRT when you need to compare the time difference, because
   that member can go back to zero.  You need to use time-subtract.
 . Last, but not least: please include ChangeLog-style commit log
   message for the changes.

Thanks.

Allow users to customize the maximum frequency that
`cpp-progress-message' prints messages.

	* progmodes/cpp.el (cpp-message-min-time-interval)
	(cpp-progress-message): Add variable
	`cpp-message-min-time-interval' to indicate the minimum time
	interval in seconds that `cpp-progress-message' prints messages.

	* progmodes/cpp.el (cpp-progress-time): Initialize to '(0 0 0 0) instead of
	0 and improve the documentation.

	* progmodes/cpp.el (cpp-highlight-buffer): Use
	`cpp-progress-message' instead of `message'.


Thanks.

Thanks, but there are still left-overs:

This should be one line, so the sentence should be shorter to fit.  If
you drop the redundant "Indicate the" part, it will come close.

> -(defvar cpp-progress-time 0)
> -;; Last time we issued a progress message.

You could leave it at 0, no need to have a list here.

This should be a single line.  Once again, please drop the uneeded
"Indicate" part.

The first sentence of the doc string should take only one line.

Thanks, updated.



Allow users to customize the maximum frequency that `cpp-progress-message' prints messages.

* progmodes/cpp.el (cpp-message-min-time-interval)
(cpp-progress-message): Add variable
`cpp-message-min-time-interval' to indicate the minimum time
interval in seconds that `cpp-progress-message' prints messages.

* progmodes/cpp.el (cpp-progress-time): Improve the documentation.

* progmodes/cpp.el (cpp-highlight-buffer): Use
`cpp-progress-message' instead of `message' to print messages.
