How to display a newly created ERC buffer.
This determines ERC's baseline, "catch-all" buffer-display
behavior. It takes a backseat to more specific options, like
erc-interactive-display, erc-auto-reconnect-display, and
erc-receive-query-display.
The available choices are:
window - in another window,
window-noselect - in another window, but don't select that one,
frame - in another frame,
bury - bury it in a new buffer,
buffer - in place of the current buffer,
DISPLAY-FUNCTION - a display-buffer-like function
Here, DISPLAY-FUNCTION should accept a buffer and an ACTION of
the kind described by the Info node (elisp) Choosing Window.
At times, ERC may add hints about the calling context to the
ACTION's alist. Keys are symbols such as user options, like
erc-buffer-display, or module minor modes, like
erc-autojoin-mode(var)/erc-autojoin-mode(fun). Values are non-nil constants specific to
each. For this particular option, possible values include the
symbols
JOIN, PRIVMSG, NOTICE, erc, and erc-tls.
The first three signify IRC commands received from the server and
the rest entry-point commands responsible for the connection.
When dealing with the latter two, users may prefer to set this
option to bury and instead call DISPLAY-FUNCTION directly
on (server) buffers returned by these entry points because the
context leading to their creation is plainly obvious. For
additional details, see the Info node (erc) display-buffer.
Note that when the selected window already shows the current
buffer, ERC pretends this option's value is bury unless the
variable erc-skip-displaying-selected-window-buffer is nil or
the value of this option is DISPLAY-FUNCTION.
