Dear maintainers,
I have written a small patch for 'time.el'. It adds a face to the
date+time of 'M-x display-time-mode'.
Should I install this on 'master'? Any changes to make to it?
All the best,
Protesilaos (or simply "Prot")

This entry is IMO too long for such a simple and minor change. Just
saying something like
** New face 'display-time-time-and-date-indicator'.
This is used for displaying the time and date components of
'display-time-mode'.
should be enough.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
"Face for `display-time-format'."
Thanks.

Thank you for the feedback! I made the changes and installed the patch.
Closing the bug now.

Thatʼs a very repetitive name. How about just
`display-time-indicator-face' (although I have a vague memory of there
being a guideline to not end faces in -face)

Indeed, the name is awkard. I also remember that use of "-face" is
discouraged, but could not find the resource for it.
My initial idea was to use "display-time-face", which would also be
symmetric with "display-time-mail-face". Note though that the latter is
defined as a 'defcustom', so I wasn't sure what the right approach is.

I canʼt find anything in the elisp manual. But I do note that all the
font-lock faces end in '-face'

`defface' defined faces are customizable, so I donʼt think it matters.

Okay. Any thoughts on renaming the face to 'display-time-face'? Maybe
some other name is better?

Iʼm bad at naming at the best of times. 'display-time-face' sounds
fine to me (or even 'display-time' if we obey the edict in the elisp
manual).

Please don't end the face's name with "-face". I suggest
display-time-date-and-time instead.

It's mentioned in the description of defface (C-h S defface).

I was going to say the same thing. Perhaps
it should _also_ be said in the doc string
(but that's already a bit long, and it has
a link to the Elisp manual doc). IMO that
would help.
___
As for the face name: This face is intended
(only) for the mode-line, no? That's more
important (besides respecting the guideline)
than including "-face" in the name.
Maybe something like `mode-line-datetime'?
Standard faces used generally in the mode-line
have that prefix `mode-line-'. Other faces
used in the mode-line (e.g. for different
modes) typically have "mode-line" as suffix
or infix.
mode-line
mode-line-buffer-id
mode-line-emphasis
mode-line-highlight
mode-line-inactive
compilation-mode-line-exit
compilation-mode-line-fail
compilation-mode-line-run
