The erc-nicks module does not respect erc-pal-face and erc-fool-face
when assigning a face for a nick, specifically when a user writes a
message that includes a nick of a pal or fool, leading to the faces
being different in the nick tag (<your_nick>) and the message
(ex. "your_nick: hi").
Reproduction config:
(use-package erc
:defer t
:config
(custom-set-faces
`(erc-pal-face ((t (:foreground "red")))))
(setopt erc-modules
(seq-union '(nicks) erc-modules))
:custom
(erc-nicks-colors '("yellow"))
(erc-pals '("trev")))
In the above config, you will notice that "<trev>" will be red, but when
someone mentions "trev" in a message, the nick will be yellow (instead
of red).
Attached is a proposed patch. Feedback needed and welcome!

Subject: [PATCH] Make erc-nicks respect pal and fool faces
The erc-nicks colors should not highlight over a nick that is a pal or a
fool.
This change checks if the nick is a pal or a fool and uses the respective face
in erc-nicks--face-table from there on out.

Thanks for the bug report. The good news is I can definitely reproduce
this. :)
But whether it's a bug and how to go about addressing it is a bit more
involved, I'm afraid. As luck would have it, this issue or something
similar actually comes up every now and again but not so much in the
context of `nicks' (or `erc-highlight-nicks' before it).
Anyway, as you may have noticed, the `nicks' module formally depends on
the `button' module and a new (5.6+) `button'-provided interface:
`erc-button--modify-nick-function'. IMO, this coupling is an acceptable
trade-off because `nicks' can piggyback on the token scanning that
`button' provides. The `button' module itself runs its code at depth 30
on `erc-insert-modify-hook', which is earlier than the `match' module's
50. This means it applies its faces _before_ `match' ever touches them.
What probably threw you off in perhaps thinking `match' had a say before
`nicks' was the presence of useless faces from `match' in the default
value of the option `erc-nicks-skip-faces'. That's indeed my bad: they
shouldn't be there at all (and a patch to fix this would be most
welcome). To that end, I'd much prefer we kept `nicks' and `match' as
loosely coupled as possible for the sake of long-term maintainability,
although I'm sure your current proposal is quite effective from a purely
pragmatic POV.
FWIW, the way `match' has always "worked" is that each category ("fool",
"keyword", etc.) has an accompanying "match type," like `keyword',
`nick', `message', etc., configured by an option like
`erc-current-nick-highlight-type'. However, unlike the "current-nick"
and "keyword" categories, "pal" and "fool" don't offer an equivalent of
`nick-or-keyword' or `keyword' for their corresponding highlight
options. This accounts for the undesirable behavior you observe (why
mentions aren't ever highlighted).
It likely won't surprise you to hear that expanding the match-type
selection of "fool" and "pal" to full parity with those of the other
categories has actually been suggested many times over in the past. In
fact, ISTR at least one patch/gist thingy floating around somewhere on
the wiki webs that purports to tackle this.
In terms of approaches, I think a more "modern" solution would address
this task by mimicking the way `nicks' modifies message text (but only
when `button' is loaded or slated to be via membership in
`erc-modules'). That is, it'd apply its faces indirectly by hooking into
`erc-button--modify-nick-function'. However, such an approach would also
likely involve more surgery (possibly a full refactor of
`erc-match-message'). And without adequate test coverage, I'd be
reticent to go that route. (BTW, the entire `match' module is severely
under-covered, so anything to remedy the situation would also be
welcome.)
As for a more traditional, non-`button' approach: I might be amenable to
a super minimal patch so long as it leaves a very light footprint. A
rough plan would be something like:
1. Add `keyword' and `nick-or-keyword' to highlight-type options for
fools and pals.
2. Ensure the "-p" predicates for fools and pals consider the entire
message. IIRC, only one of them does.
3. In, `erc-match-message', either modify the `keyword' case in the
giant `cond' or add a new one for non-"current-nick" `keyword' and
`nick-or-keyword' types to search and replace all pals and fools in
the message body (possibly including the speaker tag, for the
`nicks-or-keyword' variant).
(I'm probably missing something, but you get the idea.) If you're
willing to try this, I can help with benchmarking and adding tests. No
pressure though, obviously. Also, I very much appreciate all code
contributions, even those we don't end up using.

~~~~~~~~~~~~~~~~
Actually, when I said I could reproduce the bug, I only meant WRT pals
and fools. This last face is used for so-called "input" messages, which
are outgoing messages taken from input at the prompt (which you probably
already knew). If you're saying `nicks' _should_ highlight your own
speaker tags (or should optionally do so), please explain.
Thanks.

I see now. I did notice the depths being different but couldn't really
grok what was going on at the moment and went for more of a "hack it
till it works" approach.

I did notice this and tinkered with it, but didn't really find anything
significant when removing the pal and fool faces from it.
Thanks for the detailed explanation. I did go through with the
"traditional" approach of adding 'nick-or-keyword, but sadly gave up.
Honestly, the more I looked at ERC, the more I realized that I don't
want pals to be highlighted at all. This makes my first patch irrelevant
since the whole idea is to use one single face color every time a nick
appears (similar to weechat's nick highlighting). The same goes for a
fool, who may appear dimmed, but when someone else mentions the fool you
will see their nick as the color that erc-nicks assigns.

This is again about consistency with seeing your own nick within
brackets (<your_nick>) and in messages that other people send (when
erc-current-nick-highlight-type is 'nick-or-keyword).
Not sure what to do! I think we can just close this bug for now.

Actually, I think I steered you wrong with that outline thingy
(apologies if that led to a wild goose chase). As you've rightly
observed, the only implementation of `nick-or-keyword' is for
"current-nick", and it behaves rather unintuitively (the one for
"keyword" is a no-op). From the doc:
`nick-or-keyword' - highlight the nick of the user who typed your
nickname, or all instances of the current nickname
if there was no sending user
Anyway, mimicking that behavior for "fool" and "pal" obviously won't do.
I think we'd instead want a new variant, something like a `keyword-all'
to highlight all occurrences of a given nick, whether they be in a
speaker tag, an opening address "mention: ", or otherwise.

I believe what I said above applies here too re the either/or
proposition imposed by the "match types" currently on offer.

Hm, I guess I was confused by the `erc-my-nick-face' in
((equal nick (erc-current-nick)) 'erc-my-nick-face))))
because that concerns the face your speaker tag appears in when you
submit a comment at the prompt. Confusingly, it's actually unrelated to
`erc-current-nick-face', which is the face your mentions appear in after
being treated by `match' (or, as noted above, the face your mentioners
appear in with match types `nick-or-keyword' and `nick').
To avoid such confusion in the future, I think we should supplement
those non-namespaced faces in erc-match.el with preferred aliases, like
`erc-match-current-nick' (new faces aren't supposed to be suffixed with
"-face", I've learned).
Anyway, FWIW, there are actually existing, though perhaps somewhat
roundabout ways to force all occurrences of your nick to use the same
face (if that's ultimately what you're after):
With `match':
(use-package erc
:custom
(erc-modules `(nicks ,@erc-modules)))
(use-package erc-match
:custom-face
(erc-current-nick-face ((t ( :weight unspecified
:foreground unspecified
:inherit erc-my-nick-face)))))
Without `match':
(use-package erc
:custom
(erc-modules `(nicks ,@(remq 'match erc-modules))))
(use-package erc-nicks
:custom-face
(erc-nicks-trev@Libera.Chat-face
((t (:inherit (erc-button-nick-default-face
erc-my-nick-face))))))
Perhaps one of these should go in the manual's Sample Config.
> Not sure what to do! I think we can just close this bug for now.
I've gone ahead and done that, but feel free to continue discussing
should anything related arise (though you may have to unarchive the bug
beforehand if weeks go by). Cheers.
