bug#63569: 30.0.50; ERC 5.6: Add automatic nickname highlighting to ERC

[J.P.]

Tags: patch
Severity: wishlist

Hi people,

Highlighting nicknames belonging to predetermined categories, like
"fools" or "pals," has long been part of ERC's repertoire. And doing the
same for any number of arbitrary buckets has long been on the wishlist.
Of the various third-party renditions floating around, the most
featureful is likely erc-hl-nicks by David Leatherman. I know I'm hardly
alone in feeling that folding this package or one like it into ERC
proper would be a welcome inclusion indeed, in part because the same
sentiment has been echoed widely in #emacs and beyond for years. To that
end, some months ago, Emacs' own Stefan K. reached out to David on
GitHub, entreating as much [1]. So far, that ticket has gone unanswered
(as has another, more recent effort by Corwin over email).

In any event, I'd like to find a way to move ahead with this, possibly
by replicating (most of) hl-nicks' functionality. Attached is a
quasi-"clean-roomed" (hopefully not too cynical) knockoff/POC for your
booing pleasure. Of course, if anyone has a problem with the degree of
perceived similitude, by all means, please say so. In general, this take
aims to be simpler and more tightly integrated with ERC's other
libraries, although both qualities would likely have manifested
naturally had we been able to officially procure the genuine article
(which of course I'd still be into).

Thanks,
J.P.
