The main focus will be those aspects impacting ERC 5.6 and how they integrate with the upstream display-buffer facility provided by window.el. In a sense, this is a spiritual successor to bug#51753: ERC switches to channel buffer on reconnect and will inherit the outstanding display-related portions of bug#60428: 30.0.50; ERC >5.5: Make M-x erc a more welcoming entry point the most recent being this proposal: > This bug's original patch set tried to walk back an austere aspect of > bug#51753's changes that lumped interactive buffer creation in with > protocol driven creation.

However, as pointed out by Corwin on > Libera, this did not account for interactive /JOINs. > > The attached patch aims to address this oversight as well as simplify > the display-options picture a bit further by consolidating the roles of > `erc-interactive-display' and `erc-query-display'.

This patch also adds an interface > for other such commands to use for detecting when they're being called > from the command line. Despite this, I'm still rather unsure about merging our ancient display options. Aliasing `erc-interactive-display' to `erc-query-display' seems sane because the latter only appears once, in an interactive command. A more daring and arguably more meaningful move would be to repurpose `erc-auto-query' (newly aliased to `erc-receive-query-display') as something like a more general `erc-receive-display', which could cover display handling for anything protocol driven (i.e., "non-interactive"). Among the reasons to abstain might be 1. it would necessarily involve redefining the meaning of the option's nil value to mean "fall back to erc-join-buffer" instead of "print to the server buffer instead," which has no available alternative 2. it invites an initial security risk (reminiscent of bug#51753) or at least a service interruption For the first point, redefining the nil value is probably justified in theory because all other values only concern themselves with where a buffer is displayed, not where messages are routed for printing or whether buffers are even created, which is the province of dedicated switches (see note below re `erc-query-on-unjoined-chan-privmsg'). So I guess this really comes down to whether providing an alternative companion option and noting it in the doc string is an acceptable trade off. Point two is more challenging but could perhaps be addressed by a one-off warning requiring a click-through, before which `erc-join-buffer' (now `erc-buffer-display') would remain in effect. There's also the matter of assigning Custom groups for these options. It'd be "nice" if we could tag these with multiple groups rather than confine them to exclusive ownership. They're currently spread over `erc-buffers', `erc-query', and `erc-display'. All seem to have valid claims when you consider their respective constituencies. It's also been casually suggested that we might consider deferring to `erc-setup-buffer' in areas not directly involved in message handling, such as in erc-sidebar, to allow the options in question to influence how buffers are displayed more generally. Not sure I have an opinion on this quite yet, but if anyone else does, please share. Lastly, I've tacked on another patch that's somewhat related in the buffer-creation (but not so much -display) sense. It concerns the restoration of the option `erc-query-on-unjoined-chan-privmsg', which was orphaned in 5.5 (by me) both out of ignorance and an abundance of caution. Thanks.

Jason Park" Date: Mon, 10 Apr 2023 17:58:05 -0700 Subject: [PATCH 2/2] [5.6] Extend erc-interactive-display to cover /JOINs * lisp/erc/erc.el (erc-buffer-display, erc-join-buffer): Swap alias and aliased so that the favored name, `erc-buffer-display', appears in the definition and in the Customize menu. (erc-query-display, erc-interactive-display): Make the former an alias for the latter because their roles were functionally redundant and thus confusing. Inherit the default value from `erc-query-display' because users are more familiar with the pop-up window behavior than a single-window replacement. (erc--called-as-input-p): New variable for "slash" commands, like `erc-cmd-FOO', to detect whether they're being called "interactively" as a result of input given at ERC's prompt. (erc-process-input-line): Bind `erc--called-as-input-p' when running slash commands. (erc-cmd-JOIN): When called interactively, schedule a callback to wrap the response handler and control how new buffers are thus displayed. * test/lisp/erc/erc-scenarios-base-buffer-display.el: New file. * test/lisp/erc/erc-scenarios-base-reconnect.el (erc-scenarios-common--base-reconnect-options, ert-deftest erc-scenarios-base-reconnect-options--buffer, erc-scenarios-base-reconnect-options--default): Move to new file erc-scenarios-base-buffer-display.el and rename. * test/lisp/erc/erc-tests.el (erc-process-input-line, erc-select-read-args, erc-tls, erc--interactive): Change expected default value of `erc-interactive-display' from `buffer' to `window'.
