(This bug could just as well be titled "Make ERC look more like
standalone clients," although that's perhaps a bit clickbaity.)


Hi,

Newcomers to ERC are occasionally dumbfounded by the absence of a
certain pair of IRC essentials, namely, a "window list" and a "nicknames
list." But what even existing users may not know is that ERC already has
both; they just don't quite work the way folks coming from other clients
might expect. This patch aims to address that as if it were a problem.

What's being proposed here is the addition of two new modules built
entirely on functionality already offered by their host libraries,
erc-status-sidebar.el and erc-speedbar.el. What's different is these
additions flirt with something somewhat verboten in ERC, and that's
changing existing defaults for non-security reasons (in this case,
chiefly for unifying UX [1]). Beyond that, these changes also hard-wire
potentially offensive choices into some of these defaults while trying
in earnest to ensure old behavior remains accessible. For example, one
module assumes no one with a non-nil `erc-header-line-format' has any
use for modes and topics in a side window. Other baked in preferences
include the nixing of all throwback icons [2] and the showing of
disconnected buffers in a muted face. The list goes on but is open for
discussion, as always.

Another consideration here is of course naming [3]. I've gone ahead and
dubbed the speedbar module 'nickbar' as a bit of an homage to its roots.
`nicklist' wasn't available because a popular module of that name was
once part of ERC, and people still use it today. For status-sidebar, I
went with `bufbar', in part for consistency but also because the
would-be canonical "status-sidebar" is already taken by the side
window's buffer for its major mode. We might also consider going with
the slightly pedestrian `buflist', which is already used by at least one
other IRC client for referring to this feature.

Lastly, I'd like to stress that these modules (thankfully) won't be
loaded by default, which means you'll need to add `bufbar' and `nickbar'
to `erc-modules' when trying them out. Note that this patch set
currently depends on bug#63569 [3], whose changes need applying
beforehand.

Thanks!


[1] My justifications for taking such liberties are at best anecdotal,
    based mostly on personal impressions of prevailing usage patterns
    and the perceived motivations behind them. A few examples:

    a. The relative newness of erc-status-sidebar.el, its lack of an
       associated module, and its absence from ERC's Custom menu all
       point to its defaults being somewhat more free for the changing.
       The speedbar integration likewise lacks a module, and its
       graphical-only nature means its set of users currently excludes
       anyone using ERC from a terminal. (Less expected fallout from the
       proposed churn, IOW.)

    b. Both libraries provide an always-open side window (or, in
       speedbar's case, frame), which imposes a specific layout on the
       user, something that's relatively rare in Emacs outside of
       IDE-style modes. Compare this to something like ibuffer for
       listing buffers or a hypothetical /NAMES buffer, which, if based
       on `tabulated-list-mode', would make for a more familiar means of
       reviewing channel members. The point here is that devoted users
       likely aren't messing with erc-status-sidebar or erc-speedbar in
       droves, preferring more Emacsy alternatives instead.

    c. Newcomers can't be bothered with an overly involved setup if it
       requires carefully exploring options before trying. But they're
       perfectly willing to copy/paste gobs of configuration or even
       mindlessly follow a minutes long Customize itinerary, so long as
       the promise of emerging with something resembling their present
       idea of what makes an IRC client remains within reach. By
       introducing these modules "preconfigured," I'm positing that
       these preconceived notions typically include a reactive window
       list and/or nick list. That said, my hope is that these users
       will eventually gravitate toward the more Emacs-native way of
       doing things, at which point these modules will have served their
       primary purpose (of acting as bait).

[2] My reason for 86'ing the icons outright in the speedbar's new
    "window mode" is consistency. I figure anyone who wants the vanilla
    experience wants it in full and thus also wants a separate frame.
    That said, I suppose we could add a knob for tweaking this (or any
    of the other hard-coded choices mentioned), but IMO doing that
    unprovoked just contributes to "options sprawl."

[3] FWIW, all module names in contention flout our supposed policy of
    preferring those that align with host libraries and the features
    they `provide'.

* lisp/erc/erc-common.el (erc--module-toggle-prefix-arg): Add internal
variable for preserving the `arg' passed to a module's minor-mode
toggle, which was previously discarded.  Doing this lets modules that
are more interactive in nature overload their mode toggles with
alternate behaviors.
(define-erc-module): Bind `erc--module-toggle-prefix-arg' to the `arg'
parameter, which is normally defined inside a `define-minor-mode' body
form.
* test/lisp/erc/erc-tests.el (define-erc-module--global,
define-erc-module--local): Expect activation body to be wrapped by a
let form binding `erc--module-toggle-prefix-arg'.

Subject: [PATCH 3/5] [5.6] Add preset styles to erc-status-sidebar

* lisp/erc/erc-networks.el (erc-networks--rename-server-buffer): Store
`erc-networks--id' in process object's plist.
* lisp/erc/erc-status-sidebar.el (erc-status-sidebar): Change parent
from `convenience' to `erc'.
(erc-status-sidebar-channel-format):
Mention in doc string that it depends on new option
`erc-status-sidebar-style'.
(erc-status-sidebar-highlight-active-buffer): New option to control
whether the current window's target is highlighted in the status bar.
(erc-status-sidebar-style): New option to determine whether servers
and queries also appear in the sidebar.
(erc-status-sidebar-click-display-action,
erc-status-sidebar-singular): New options.
(erc-status-sidebar-get-window): Consider
`erc-status-sidebar-singular'.
(erc-status-sidebar-open): Fix toggle functionality that somehow fell
through the cracks after the adoption of the package into ERC proper.
(erc-buflist-mode, erc-buflist-enable, erc-buflist-disable): New
module named `buflist' instead of `sidebar', which is more easily
confusable with `speedbar'.  The preferred name, `status-sidebar' was
unavailable because its minor-mode would have been
`erc-status-sidebar-mode', which is already taken by the major mode
used for status-bar buffers themselves.
(erc-status-sidebar-toggle): Ignore `erc-status-sidebar-singular'.
(erc-status-sidebar--trimpat, erc-status-sidebar--prechan): Add helper
vars for new sorting function, allowing it to honor the existing
interface, which only expects one argument.
(erc-status-sidebar-prefer-target-as-name): New function for
determining buffer name, preferring targets for target buffers.
(erc-status-sidebar-get-channame): Use internal API to help determine
name of buffer in sidebar.
(erc-status-sidebar-prefer-target-as-name,
erc-status-sidebar--show-disconnected,
erc-status-sidebar-all-target-buffers,
erc-status-sidebar-default-allsort): Add new naming and sorting
functions and associated helper functions and variables.
(erc-status-sidebar--active-marker,
erc-status-sidebar--set-active-line): New variable and function for
highlighting the active target in the status bar.
(erc-status-sidebar-default-insert,
erc-status-sidebar-pad-hierarchy): New functions for visiting various
stages of buffer modification when rendering sidebar.
(erc-status-sidebar-click): Appeal to option
`erc-status-sidebar-display-action' for `pop-to-buffer' action.
(erc-status-sidebar-scroll-up, erc-status-sidebar-scroll-down,
erc-status-sidebar-recenter): Add commands to scroll and
recenter sidebar from a target buffer's window.
(erc-status-sidebar-refresh): Consider presets and new options when
rendering sidebar.  Disable `erc-buflist-mode' when active.
(erc-status-sidebar-set-window-preserve-size): Ignore
`erc-status-sidebar-singular'.
(erc-status-sidebar-mode): Make non-interactive to avoid confusion
when folks run "M-x erc-status-sidebar-mode" expecting a module
toggle.
* test/lisp/erc/erc-scenarios-status-sidebar.el: New file.
* test/lisp/erc/resources/base/gapless-connect/foonet.eld: Fix wrong
manifest for channel and extend PASS timeout.

Subject: [PATCH 4/5] [5.6] Add erc-status-sidebar integration to erc-speedbar

* lisp/erc/erc-speedbar.el: Require `erc-button' atop file and don't
bother loading `dframe', which `speedbar' handles for us.
(erc-speedbar-hide-mode-topic): New option determining whether to hide
the mode and topic.
(erc-speedbar-my-nick-face): New option for determining face to use
when displaying user's current nick.
(erc-speedbar-browser): Call `erc-install-speedbar-variables'
explicitly and remove top-level `with-eval-after-load'.
(erc-speedbar-insert-target): Add parenthesized channel count after
channel name in server and channel views.
(erc-speedbar-expand-channel): Hide mode and topic depending on option
`erc-speedbar-hide-mode-topic' and pass buffer to
`erc-speedbar-insert-user'.
(erc-speedbar--nick-face-function): New internal function-interface
variable.
(erc-speedbar--highlight-self-and-ops): New function to serve as
default value for `erc-speedbar--nick-face-function'.
(erc-speedbar--on-click): Dispatch `erc-nick-popup' after trimming
status chars.
(erc-speedbar-insert-user): Revise doc string.  Call
`erc-speedbar--nick-face-function' to determine face.  Change
token for both expansion and on-click text props.  Assign
`erc-speedbar--on-click' as the mouse handler for nick items.
(erc-speedbar-emulated-sidebar-width): New option to control width
of nicknames list window.
(erc-speedbar): Mention `erc-nickbar-mode' in group doc string.
(erc-speedbar--buffer-options): Variable to override options locally
in speedbar buffer.
(erc-speedbar--hidden-speedbar-frame): Add variable to hold original
`speedbar-frame' before spoofing by setting to selected frame
containing window showing ERC buffer.
(erc-speedbar--dframe-controlled) Add function to overwrite
`speedbar-frame-mode' as `dframe-controlled' in speedbar buffer.
(erc-speedbar--emulate-sidebar-set-window-preserve-size,
erc-speedbar--status-sidebar-mode--unhook): Add function
to ensure status sidebar is showing correctly and helper to
unregister from hook on teardown.
(erc-speedbar--emulate-sidebar): Add function to
control sidebar nicknames setup.
(erc-speedbar--toggle-nicknames-sidebar): Add toggle function
for sidebar or speedbar.
(erc-speedbar--ensure): Add helper function to show speedbar if its
hidden or create one if none exists.
(erc-nickbar-mode, erc-nickbar-enable, erc-nickbar-disable):
Add new module.
(erc-speedbar-toggle-nicknames-window-lock,
erc-speedbar-close-nicknames-window): Add commands to close speedbar
window and toggle its cyclability.
(erc-speedbar--compose-nicks-face): Add helper for nicks integration.
* test/lisp/erc/erc-scenarios-status-sidebar.el
(erc-scenarios-status-sidebar--nickbar): New test, unfortunately only
runs in terminals.

+** ERC's status-sidebar now has an accompanying module.
+Users can now add 'bufbar' to 'erc-modules' to achieve the same effect
+as toggling 'erc-status-sidebar-open' manually at the start of an IRC
+session.  The module has also been outfitted to show channels and
+queries under their respective servers by default.  To avoid
+confusion, the major mode used for the sidebar buffer itself,
+'erc-status-sidebar-mode', is no longer available interactively.
+
+** A new spin on a classic integration in erc-speedbar.
+Add 'nickbar' to 'erc-modules' to spawn a dynamically updating side
+window listing all the users in any target buffer.  It's powered by
+the same speedbar.el integration you've always known, except this
+one's optionally accessible from the keyboard, just like any other
+side window.  Hit '<RET>' over a nick to spawn a "/QUERY" or a
+"Lastlog" (Occur) session.  See 'erc-nickbar-mode' for more.

 ** The option 'erc-timestamp-use-align-to' is more versatile.
 While this option has always offered to right-align stamps via the
 'display' text property, it's now more effective at doing so when set
