Thus, items containing special characters, like "boo[m]" or "lol.fun.dad", tend to be ineffective. Worse, invalid regexps containing things like unmatched brackets create errors in the process filter. Something else not included that perhaps should be is a clearer indication that items added interactively can match any substring in a candidate without regard for boundaries. It may also be worth contrasting this with what's ultimately highlighted. For example, if you "M-x erc-add-pal RET bo RET", then "" (minus the brackets) will be highlighted. Compare this to keywords, where only the matched portion appears in a designated face. Documentation aside, it might also be nice to retain a means of interactively adding a regexp verbatim (IOW, the old behavior minus the unhelpful completion list). Perhaps this can be done via universal argument. BTW, the individual who originally brought this to our attention on Libera also mused about a command for jumping between keywords, so I've included something sketchy to that effect. However, it suffers from an intermittent issue that I can't yet reproduce reliably: basically, when first invoked, it sometimes makes Emacs unresponsive for a few seconds. If I can't manage to tame it, I'll just drop it from this patch set. Lastly, these changes (as presented) uphold the proud ERC tradition of mutating custom options on behalf of a user. If this is truly objectionable, then I can switch to network-local analogs instead. However, such a move may adversely affect third-party code, given that this module's been around in roughly the same form for some 20 odd years. Thanks, J.P. P.S. This bug is not (yet) associated with any planned ERC release.
