branch: master
commit 3f1ce47fe7eb4809bfa9ef035caae748c3c5d729
Author: F. Jason Park <jp@neverwas.me>
Commit: F. Jason Park <jp@neverwas.me>

    ; Add face customization to ERC's sample config
    
    * doc/misc/erc.texi (Sample Configuration): Move `erc-modules' twiddling
    from a `use-package' :config section to a :custom section.  In the past,
    this would sometimes provoke module-loading issues, but it seems to work
    fine on Emacs 30, even with repeated eval'ing of the `use-package' form.
    This sample config is meant for users running the latest release anyhow.
    Also add a new `use-package' block for `erc-match' showing how to
    customize a face using inheritance.  Add a corresponding section further
    down showing the same via Customize.

+Try customizing another face, this time with inheritance.  ERC's match
+module highlights your nick whenever someone mentions you in
+conversation.  However, some users don't like that this face differs
+from the one in your own messages.  Let's change that.  Type @kbd{M-x
+customize-group @key{RET} erc-faces @key{RET}}.  Either search for the
+word ``Current'' or type @kbd{M-x customize-face @key{RET}
+erc-current-nick-face @key{RET}}.  Untick @samp{Weight} and
+@samp{Foreground}, then click the ``Show All Attributes'' button below
+them.  Navigate down to the @samp{Inherit} box, tick it, hit
+@samp{[INS]}, and type @code{erc-my-nick-face} in the @samp{Face} field.
+Hit @kbd{C-x C-s} to save.

 ERC users tend to be picky about the mode line.  If you find that
 you'd rather not see changes when people join and leave channels,
 customize the option @code{erc-track-faces-priority-list}.  When
