ef4a3c2a6d ; Fix example in display-buffer section of ERC manual
* doc/misc/erc.texi: Fix `display-buffer-alist' example and mention
that it's only meant for users of Emacs 29 and above.
* test/lisp/erc/erc-tests.el (erc-setup-buffer--custom-action): Add
simplistic test case for example in manual.

e1b8dbe9ea ; Allow alternate ert-info text in ERC test utility
* test/lisp/erc/erc-tests.el
(erc-tests--assert-printed-in-subprocess): Don't insist that arguments
to the Emacs "-load" invocation option be actual disk files.
* test/lisp/erc/resources/erc-d/erc-d-t.el
(erc-d-t--wait-message-prefix, erc-d-t-wait-for, erc-d-t-ensure-for):
Add and use new variable to make `ert-info' message prefix adjustable.
The immediate use for this is to make it easier to distinguish between
consecutive assertions in which the first waits for a condition and
the second ensures it holds for some duration.
* test/lisp/erc/resources/erc-d/erc-d-u.el
(erc-d-u--read-exchange-default): Skip killed buffers.
* test/lisp/erc/resources/erc-d/erc-d.el: Typo.

c96a626dce Allow login to contain NUH delimiters in erc-parse-user
* lisp/erc/erc.el (erc--parse-user-regexp-legacy,
erc--parse-user-regexp-pedantic): New constants.  The first is the
original pattern that matches across line endings.  The second
disallows multiline strings and interprets excess delimiting
characters as part of the middle, "user" component as per RFC1459.
The latter distinction is largely academic because most servers reject
such logins anyway, but bridges to other protocols and future
extensions may need to exploit this for novel uses.
(erc--parse-user-regexp): New variable, currently set to
`erc--parse-user-regexp-legacy'.
(erc-parse-user): Keep original pattern as default, but do so
indirectly via `erc--parse-user-regexp'.
* test/lisp/erc/erc-tests.el (erc-parse-user): New test.

75b3fb3cb4 Ignore erc-response objects in error-notice helper
* lisp/erc/erc-button.el (erc-button--display-error-notice-with-keys):
Remove `parsed' `erc-response' positional parameter, and don't pass it
to `erc-display-message' because the latter adds text properties
derived from such an object.  These properties can confuse other code
operating on an inserted error-notice message into thinking it
originated from the server.
* lisp/erc/erc-common.el (erc--with-dependent-type-match): Make macro
more readable.
* lisp/erc/erc-networks.el (erc-networks--set-name,
erc-networks--ensure-announced, erc-networks-on-MOTD-end): Remove
`erc-response' objects from inserted error-notices.
* test/lisp/erc/erc-button-tests.el
(erc-button--display-error-notice-with-keys): Add assertions for
overloaded first parameter.
* test/lisp/erc/erc-tests.el (erc--with-dependent-type-match): Update
expected expansion.

af547c4bbe Improve ERC's internal invisibility API
* etc/ERC-NEWS: Mention that line endings have moved from the end to
the beginning of hidden messages.
* lisp/erc/erc-fill.el (erc-fill--wrap-ensure-dependencies): Warn when
users have `erc-legacy-invisible-bounds-p' enabled, and force it to
its default value of nil in the current buffer.
(erc-fill-wrap-mode, erc-fill-wrap-enable): Move business involving
compat variable for enabling legacy hidden-message behavior to helper.
* lisp/erc/erc-match.el (erc-match--hide-fools-offset-bounds): Move
internal variable from to main library file and rename to
`erc-legacy-invisible-bounds-p'.  Also make obsolete and flip
semantics so a non-nil value enables the traditional behavior.
(erc-match--hide-message): Move to main library file and rename to
`erc--hide-message'.  Add a property-value parameter instead of
hard-coding to `erc-match'.  Also, condition behavior on renamed
compatibility flag `erc-legacy-invisible-bounds-p'.
(erc-hide-fools): Call `erc--hide-message' with own value for
`invisible' property specifically for fools.  That is, use
`match-fools' rather than `erc-match' or `erc-match-fools' to save
room when visually inspecting.  This retains the module name as a
prefix to hopefully minimize collisions with invisibility spec members
owned by non-ERC minor modes.  The `timestamp' spec member owned by
erc-stamp likewise lacks a namespace prefix, but its feature/group
affiliation is self-evident.
(erc-match--modify-invisibility-spec): Use toggle command
non-interactively for adding and removing invisibility spec member.
(erc-match-toggle-hidden-fools): Add explicit override argument and
defer to general helper for actually modifying spec.
(erc-match--toggle-hidden): New helper for toggling invisibility
spec.
* lisp/erc/erc.el (erc--merge-prop): If new value is a list, prepend
onto existing.  Add note about possible space optimization.
(erc-legacy-invisible-bounds-p): New obsolete compat variable to
enable traditional pre-5.6 invisibility interval on hidden messages.
Replaces `erc-match--hide-fools-offset-bounds-p' but has an inverted
meaning.  The new default value of nil means invisibility covers a
shifted interval consisting of the message body plus the line ending
immediately preceding it.
(erc--hide-message): New function, formerly `erc-match--hide-message'
from erc-match.el introduced in ERC 5.6.
* test/lisp/erc/erc-scenarios-match.el:
(erc-scenarios-match--invisible-stamp): Fix comment and use API
function in interactive convenience setup.
(erc-scenarios-match--find-bol): New test helper.
(erc-scenarios-match--find-eol): Fix bug affecting interactive use.
(erc-scenarios-match--stamp-left-fools-invisible,
erc-scenarios-match--stamp-right-fools-invisible,
erc-scenarios-match--stamp-right-invisible-fill-wrap,
erc-scenarios-match--stamp-both-invisible-fill-static): Update
`invisible' property from `erc-match' to `match-fools'.
(erc-scenarios-match--stamp-right-fools-invisible,
erc-scenarios-match--stamp-both-invisible-fill-static): Move test
body to function of same name for use in multiple cases.
(erc-scenarios-match--stamp-right-fools-invisible--nooffset,
erc-scenarios-match--stamp-both-invisible-fill-static--nooffset): New
test variants asserting proper hiding with old pre-5.6 invisibility
interval.
* test/lisp/erc/erc-tests.el (erc-tests--equal-including-properties):
Relocate macro higher in same file.
(erc--merge-prop): New test.  (Bug#64301)

63d8b2a59a Make erc-fill-wrap work with left-sided stamps
* etc/ERC-NEWS: Remove all mention of option `erc-timestamp-align-to'
supporting a value of `margin', which has been abandoned.  Do mention
leading white space before stamps now having stamp-related properties.
* lisp/erc/erc-backend.el (erc--reveal-prompt, erc--conceal-prompt):
New generic functions with default implementations factored out from
`erc--unhide-prompt' and `erc--hide-prompt'.
(erc--prompt-hidden-p): New internal predicate function.
(erc--unhide-prompt): Defer to `erc--reveal-prompt', and set
`erc-prompt' text property to t.
(erc--hide-prompt): Defer to `erc--conceal-prompt', and set
`erc-prompt' text property to `hidden'.
* lisp/erc/erc-compat.el (erc-compat--29-browse-url-irc): Don't
use `function-equal'.
* lisp/erc/erc-fill.el (erc-fill-wrap-margin-width,
erc-fill-wrap-margin-side): New options to control side and initial
width of `fill-wrap' margin.
(erc-fill--wrap-beginning-of-line): Fix bug involving non-string
valued `display' props.
(erc-fill-wrap-toggle-truncate-lines): New command to re-enable
`visual-line-mode' when toggling off `truncate-lines'.
(erc-fill-wrap-mode-map): Remap `toggle-truncate-lines' to
`erc-fill-wrap-toggle-truncate-lines'.
(erc-fill-wrap-mode, erc-fill-wrap-enable, erc-fill-wrap-disable):
Update doc string, persist a few local vars, and conditionally set
`erc-stamp--margin-left-p'.  When deactivating, disable
`visual-line-mode' first.
(erc-fill--wrap-continued-message-p): Use `erc-speaker' instead of
heuristics when comparing nicks between consecutive messages.
(erc-fill-wrap-nudge): Update doc string and account for left-sided
stamps.
(erc-timestamp-offset): Add comment regarding conditional guard based
on function-valued option.
* lisp/erc/erc-stamp.el (erc-timestamp-use-align-to): Remove value
variant `margin', which was originally intended to be new in ERC 5.6.
This functionality was all but useless without the internal minor mode
`erc-stamp--display-margin-mode' active.
(erc-stamp-right-margin-width): Remove unused option new in 5.6.
(erc-stamp--display-margin-force): Remove unused function.
(erc-stamp--margin-width, erc-stamp--margin-left-p): New internal
variables.
(erc-stamp--init-margins-on-connect): New function for initializing
mode-managed margin after connecting.
(erc-stamp--adjust-right-margin, erc-stamp--adjust-margin): Rename
function to latter and accommodate left-hand stamps.
(erc-stamp--inherited-props): Move definition higher up in same file.
(erc-stamp--display-margin-mode): Update function name, and adjust
setup and teardown to accommodate left-handed stamps.  Don't add
advice around `erc-insert-timestamp-function'.
(erc-stamp--last-prompt, erc-stamp--display-prompt-in-left-margin):
New function and helper var to convert a normal inserted prompt so
that it appears in the left margin.
(erc-stamp--refresh-left-margin-prompt): Helper for other modules to
quickly refresh prompt outside of insert hooks.
(erc--reveal-prompt, erc--conceal-prompt): New implementations for
when `erc-stamp--display-margin-mode' is active.
(erc-insert-timestamp-left): Convert to generic function and provide
implementation for `erc-stamp--display-margin-mode'.
(erc-stamp--omit-properties-on-folded-lines): New variable, an escape
hatch for propertizing white space before right-side stamps folded
over onto another line.
(erc-insert-timestamp-right): Don't expect `erc-timestamp-align-to' to
ever be the symbol `margin'.  Move handling for that case to one
contingent on the internal minor mode `erc-stamp--display-margin-mode'
being active.  Add text properties preceding stamps that occupy a line
by their lonesome.  See related news entry for rationale.  This is
arguably a breaking change.
* lisp/erc/erc.el (erc--refresh-prompt-hook): New hook variable for
modules to adjust prompt properties whenever it's refreshed.
(erc--refresh-prompt): Fix bug in which user-defined prompt functions
failed to hide when quitting in server buffers.  Run new hook
`erc--refresh-prompt-hook'.
(erc-display-prompt): Add comment noting that the text property
`erc-prompt' now actually matters: it's t while a session is running
and `hidden' when disconnected.
* test/lisp/erc/erc-fill-tests.el (erc-fill--left-hand-stamps): New
test.
* test/lisp/erc/erc-stamp-tests.el
(erc-stamp-tests--use-align-to--nil,
erc-stamp-tests--use-align-to--t): New functions forged from old test
bodies to allow optionally asserting pre-5.6 behavior regarding
leading white space on right-hand stamps that exist on their own line.
(erc-timestamp-use-align-to--nil, erc-timestamp-use-align-to--t):
Parameterize with compatibility flag.
(erc-timestamp-use-align-to--margin,
erc-stamp--display-margin-mode--right): Rename test to latter.
* test/lisp/erc/erc-tests.el (erc-hide-prompt): Add some assertions
for new possible value of `erc-prompt' text property.
* test/lisp/erc/resources/fill/snapshots/stamps-left-01.eld: New test
data file.  (Bug#60936)

08515350fa Add mini modules bufbar and nickbar to ERC
* doc/misc/erc.texi: Add `bufbar' and `nickbar' to known modules.
Also add `keep-place', which was missing, and remove `bbdb', which is
not part of ERC.  Add new section "Auxiliary Modules" for listing
experimental modules or those typically managed by some other feature.
* erc/ERC-NEWS: Mention new mini modules for libraries
erc-status-sidebar.el and erc-speedbar.el.
* lisp/erc/erc.el (erc-modules): Add `bufbar' and `nickbar' to
selection of offered modules.
* test/lisp/erc/erc-tests.el (erc-tests--modules): Add `bufbar' and
`nickbar'.  (Bug#63595)

30fe8703e6 Allow ERC's module toggles access to the prefix arg
* 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'.  (Bug#63595)

9bdc5c6204 Add module for colorizing nicknames to ERC
* doc/misc/erc.texi: Add `nicks' to module lineup.
* etc/ERC-NEWS: Mention new module `nicks'.
* lisp/erc/erc-nicks.el: New file.
* lisp/erc/erc.el: (erc-modules): Add `nicks'.
* test/lisp/erc/erc-nicks-tests.el: New file.
* test/lisp/erc/erc-tests (erc-tests--modules): Add `nicks' to
inventory of available modules.  (Bug#63569)

b354b3a53b Allow custom display-buffer actions in ERC
* doc/misc/erc.texi: Add new section under "Integrations" chapter
describing `display-buffer' Custom function choice for ERC's many
buffer-display options.
* etc/ERC-NEWS: Mention new function variant for all buffer-display
options.
* lisp/erc/erc-backend.el: Add forward declaration for
`erc--called-as-input-p' and `erc--display-context'.
(erc--server-reconnect-display-timer,
erc--server-last-reconnect-display-reset): Use new name for option
`erc-reconnect-display', now `erc-auto-reconnect-display'.
(erc--server-determine-join-display-context): New generic function to
determine value of `erc--display-context' during JOINs.
(erc-server-JOIN, erc-server-PRIVMSG): Set `erc--display-context' to a
symbol for the handler's IRC command, like `JOIN', for the benefit of
custom `display-buffer'-like functions running in `erc-setup-buffer'.
(erc-server-471, erc-server-471-functions, erc-server-473,
erc-server-473-functions): New handlers for JOIN rejections.  Also
remove 471 and 473 from comment at bottom of file.
(erc-server-475): Bind `erc--called-as-input-p' so that `erc-cmd-JOIN'
sets `erc-interactive-display' context.
* lisp/erc/erc-join.el (erc-autojoin-mode, erc-autojoin-enable,
erc-autojoin-disable): Kill local variable
`erc-join--requested-channels'.  Add and remove
`erc-join--remove-requested-channels' to/from various server-handler
hooks for JOIN rejection numerics.
(erc-join--requested-channels): New local variable to remember
channels we've attempted to JOIN this session that haven't yet been
confirmed by the server.
(erc-join--remove-requested-channel): New JOIN rejection handler to
stop tracking channel in `erc-join--requested-channels'.
(erc--server-determine-join-display-context): module-specific
implementation of generic function for `erc-autojoin-mode'.
(erc-autojoin--join): Remember channels slated for JOIN'ing.
* lisp/erc/erc.el (erc--buffer-display-choices): New helper constant
for defining common `:type' for all buffer-display options.
(erc-buffer-display, erc-interactive-display,
erc-auto-reconnect-display, erc-receive-query-display): Use helper
`erc--buffer-display-choices' for defining `:type', which
includes a new choice for a `display-buffer'-like function.
(erc-reconnect-display, erc-auto-reconnect-display): Alias former to
latter, now the preferred name.
(erc-reconnect-timeout, erc-auto-reconnect-timeout): Change name from
former to latter.  This option is new in ERC 5.6.
(erc-reconnect-display-server-buffers): New option.
(erc-buffer-do): Revise doc string.
(erc--display-context): New variable, an alist of "context tokens" to
be forwarded as the "action alist" to `erc-buffer-display' functions.
(erc-skip-displaying-selected-window-buffer): New variable, deprecated
at birth, to act as an escape hatch for folks who don't want to skip
the displaying of buffers already showing in the selected window.
(erc--display-buffer-overriding-action): Local variable allowing
modules to influence the displaying of new ERC buffers independently
of user options.
(erc-setup-buffer): Do nothing when the selected window already shows
current buffer unless user has provided a custom display function.
Accommodate new Custom choice function values, like `display-buffer'
and `pop-to-buffer'.
(erc-open): Run `erc-setup-buffer' when option
`erc-reconnect-display-server-buffers' is non-nil, even for existing
server buffers.  Bind `display-buffer-overriding-action' to the value
of `erc--display-buffer-overriding-action' around calls to
`erc-setup-buffer'.
(erc-select-read-args): Add `erc--display-context' to environment.
(erc, erc-tls): Bind `erc--display-context' around calls to
`erc-select-read-args' and main body.

format templates for JOIN rejection messages.
* test/lisp/erc/erc-scenarios-base-buffer-display.el
(erc-scenarios-base-buffer-display--defwin-recbury-intbuf,
erc-scenarios-base-buffer-display--defwino-recbury-intbuf,
erc-scenarios-base-buffer-display--count-reset-timeout): Use preferred
name `erc-auto-reconnect-display' for `erc-reconnect-display'.

* test/lisp/erc/erc-tests.el (erc--initialize-markers): Fix
unrealistic call to `erc-open'.
(erc-setup-buffer--custom-action): New test.
(erc-select-read-args, erc-tls, erc--interactive, erc-server-select):
Expect new environment binding for `erc--display-context'.

6a96b86268 Add text props for CTCP messages and speakers in ERC
* etc/ERC-NEWS: Mention reduction in boldness of `erc-notice-face' and
`erc-action-face'.
* lisp/erc/erc-fill.el (erc-fill-spaced-commands,
erc-fill--spaced-commands): Rename former to latter and demote from
user option to internal variable.
(erc-fill): Change `erc-fill-spaced-commands' to
`erc-fill--spaced-commands'.
(erc-fill--wrap-continued-message-p): Use more precise `erc-ctcp' text
prop instead of face-based heuristic to detect CTCP ACTION message.
(erc-fill--wrap-action-dedent-p): New variable to toggle whether
`line-prefix' is applied to CTCP ACTION messages.  This exists less
to accommodate user preferences and more for third-party code that
assumes the first non-whitespace span in every message is a nick.
(erc-fill-wrap): Look for `erc-speaker' property before falling back
on word at point.  Use `erc-ctcp' to detect CTCP ACTION messages.
* lisp/erc/erc.el (erc-notice-face, erc-action-face): Prefer weight of
`semi-bold' when available so that buttonization is at least somewhat
perceptible in notices and action messages.
(erc-send-action): Ensure nickname passed to `erc-display-message' has
`erc-speaker' property and `erc-ctcp' ACTION property.
(erc--own-property-names): Add `erc-speaker' to lineup.
(erc-format-privmessage): Don't clobber `erc-nick-prefix-face'.  That
is, retain face applied to a leading stretch of characters in the
`nick' parameter, but continue to discard trailing faces.
(erc-format-my-nick, erc-ctcp-query-ACTION): Add new text property
`erc-speaker' to the nick portion of the formatted speaker label.  Do
this to assist modules, like `button' and `match', that currently
re-parse speakers in inserted messages.
(erc-process-ctcp-query): Add `erc-ctcp' property to entire message
before insertion hooks see it.
* test/lisp/erc/erc-fill-tests.el (erc-fill-tests--compare): Warn
about certain unreliable comparisons if generalizing helper for use by
other modules.
* test/lisp/erc/erc-tests.el (erc-tests--equal-including-properties):
New helper compat macro.
(erc-format-privmessage): New test.  (Bug#64301)

4f3d036957 Simplify erc-button-add-nickname-buttons
* lisp/erc/erc-button.el (erc-button--nick): Remove `face' slot, which
was set to `erc-button-face' by default.  It's ignored when the button
is a nick and thus useless and misleading.
(erc-button-add-nickname-buttons): Rework and reflow for readability.
Don't bind or set `erc-button' face because it's ignored when dealing
with nicks.  Don't return the value of face options when calling a
`form' function because they can be nil in practice even though their
Custom type specs do not say so.
* lisp/erc/erc-common.el (erc--with-dependent-type-match): Add helper
macro for Custom :type defs that incur warnings from `setopt' due to
some missing dependency.  This occurs when specifying a :type of
`face' instead of `symbol' and the option's default value includes
faces from another library that hasn't been loaded.
* lisp/erc/erc.el (erc--get-speaker-bounds): New helper function to
retrieve bounds of a speaker label when present.
* test/lisp/erc/erc-tests.el (erc--with-dependent-type-match): Add
test.  (Bug#64301)

96785a8037 Deprecate erc-server-alist and erc-server-select
* etc/ERC-NEWS: Announce deprecation of `erc-server-alist' and
`erc-server-select'.
* lisp/erc/erc-networks.el: Comment out call to `erc-get' at end of
file.
(erc-server-alist) Change shape to accommodate a fifth member: TLS
ports.  Add default TLS ports for Libera.Chat and OFTC.  Deprecate
option.
(erc-ports-list): Overload for internal use to accept a number instead
of a list, but don't advertise this fact.
(erc-networks--server-select): Convert `erc-server-select' into a
function that performs the same prompting but returns a full URL or a
host name instead of calling `erc'.
(erc-server-select): Move to erc.el.
* lisp/erc/erc.el (erc--prompt-for-server-functions): New variable to
allow callers of `erc-select-read-args' to affect how server-prompting
is handled without adding additional params.
(erc-select-read-args): Defer to `erc--prompt-for-server-function'
when non-nil.
(erc-server-select): New transplanted function, a deprecated, now
TSL-aware version of the old quirky entry point from erc-networks.el.
Reimplemented as a simple wrapper for `erc'.
* test/lisp/erc/erc-networks-tests.el (erc-ports-list): New test.
* test/lisp/erc/erc-tests.el (erc-server-select): New test.

* lisp/erc/erc-compat.el (erc-compat--28-split-string-shell-command,
erc-compat--split-string-shell-command): Remove unused function and
macro.
* lisp/erc/erc-dcc.el (erc-cmd-DCC): Use own arg-parsing function.
* lisp/erc/erc.el (erc--shell-parse-regexp,
erc--split-string-shell-cmd): New regexp constant and arg-parsing

d0325e2309 Revert "Account for leading timestamps in erc-match"
This reverts commit 99d74dcd45 but keeps
the test file test/lisp/erc/erc-scenarios-match.el.  It also
implements a partial alternative solution by undoing the reordering of
insert hooks owned by the `stamp' and `match' modules.  The initial
reordering stems from d880a08f "Cement ordering of essential hook
members in ERC" and was intended to address the problem of timestamps
not being hidden in matched "fool" messages.  However, a more
comprehensive solution is being pursued as part of bug#64301.  The
following changes differ from those in a pure revert.

* erc/ERC-NEWS: Fix erroneous claim about relative hook ordering
pre-5.6.
* lisp/erc/erc-match.el (erc-match-mode, erc-match-enable): Lower hook
depth of `erc-match-message' in `erc-insert-modify-hook' from 60 to
50.
(erc-text-matched-hook): Retain cleaned-up portion of revised doc
string instead of reverting completely.
* lisp/erc/erc-stamp.el (erc-stamp-mode, erc-stamp-enable): Raise
depth of `erc-add-timestamp' in `erc-insert-modify-hook' and
`erc-send-modify-hook' from 50 to 60.
* test/lisp/erc/erc-scenarios-match.el
(erc-scenarios-match--stamp-left-current-nick
erc-scenarios-match--stamp-left-fools-invisible): Temporarily disable
the latter and fix expected hook ordering.
* test/lisp/erc/erc-tests.el (erc--essential-hook-ordering): Fix
expected order of default insert hooks.  (Bug#60936)

2daa71f932 Don't insert prompt input before markers in ERC
* etc/ERC-NEWS: Update entry in 5.6 section announcing a persistent
prompt.
* lisp/erc/erc-dcc.el (erc-dcc-chat-setup): Use helper
`erc--initialize-markers' to set up prompt.
* lisp/erc/erc.el (erc--initialize-markers): Change
`erc-insert-marker' type to t.  Do this to spare modules that want to
remember the current message location from resorting to workarounds,
like leaving a marker one char before the end of a message, which is
not foolproof.
(erc--refresh-prompt): Temporarily change type of `erc-insert-marker'
when inserting prompt.
(erc-display-line-1): Insert incoming message normally instead of
forcing before markers, thus respecting markers left by third parties.
Strictly speaking, this is a breaking change.
(erc-display-msg): Insert normally instead of calling
`insert-before-markers', which was a regression introduced by 05f6fdb9
"Preserve ERC prompt and its bounding markers".
* test/lisp/erc/erc-dcc-tests.el
(erc-dcc-tests--dcc-handle-ctcp-send,

`erc--restore-initialize-priors' to preserve last session's indicator
position, if any.
(erc-keep-place-indicator-mode, erc-keep-place-indicator-enable): Use
convenience function to show missing-dependency notice.
* lisp/erc/erc-sasl.el (erc-sasl-auth-source-password-as-host): Merge
redundant `when' forms for clarity.
(erc-sasl--init): Remove unused function.
(erc-sasl-mode, erc-sasl-enable): Use helper to restore
`erc-sasl--options', essentially inlining the body of the now defunct
`erc-sasl--init'.
* lisp/erc/erc.el (erc--restore-initialize-priors): New macro to help
local modules and mode hooks prefer existing state over initializing
anew.
(erc--warn-once-before-connect): Add helper function to display
an "error notice" just after module setup.
(erc-accidental-paste-threshold-seconds) Improve doc string.
* test/lisp/erc/erc-goodies-tests.el
(erc-controls-highlight--examples, erc-controls-highlight--inverse,
erc-controls-highlight--motd, erc-keep-place-indicator-mode): Remove
feature check.  For the latter, also start fake process and shadow
`erc-connect-pre-hook'.
* test/lisp/erc/erc-tests.el (erc--restore-initialize-priors): New
test.  Also see test/lisp/erc/erc-scenarios-base-local-modules.el for
a more realistic exercising of this functionality.  (Bug#60936)

35dd1ade7f Preprocess prompt input linewise in ERC
* etc/ERC-NEWS: Mention revised role of `erc-pre-send-functions'
relative to line splitting.
* lisp/erc/erc-common.el (erc-input): Add new slot `refoldp' to allow
`erc-pre-send-functions' members to indicate that splitting should
occur a second time after all members have had their say.
(erc--input-split): Specify some defaults for overridden slots and
explicitly declare some types for good measure.
* lisp/erc/erc-goodies.el (erc-noncommands-mode,
erc-noncommands-enable, erc-noncommands-disable): Replace
`erc-pre-send-functions' with `erc--input-review-functions'.
* lisp/erc/erc-ring.el (erc-ring-enable, erc-ring-disable,
erc-ring-mode): Subscribe to `erc--input-review-functions' instead of
`erc-pre-send-functions' for `erc--add-to-input-ring'.
* lisp/erc/erc.el (erc-pre-send-functions): Note some nuances
regarding line splitting in doc string and note that a new slot is
available.
(erc--pre-send-split-functions, erc--input-review-functions): Rename
former to latter, while also obsoleting.  Remove large comment.  Add
new default member `erc--run-input-validation-checks'.
(erc-send-modify-hook): Replace the obsolete `erc-send-pre-hook' and
`erc-send-this' with `erc-pre-send-functions' in doc string.
(erc--check-prompt-input-for-excess-lines): Don't trim trailing
blanks.  Rework to also report overages in characters as well as
lines.
(erc--run-input-validation-hooks): New function to adapt an
`erc--input-split' object to `erc--check-prompt-input-functions'.
(erc-send-current-line): Run `erc--input-review-functions' in place of
the validation hooks they've subsumed.  Call `erc--send-input-lines'
instead of the now retired but not deprecated `erc-send-input'.
(erc--run-send-hooks, erc--send-input-lines): New functions that
together form an alternate version of `erc-send-input'.  They operate
on input linewise but make accommodations for older interfaces.
* test/lisp/erc/erc-tests.el (erc-ring-previous-command): Replace
`erc-pre-send-functions' with `erc--input-review-functions'.
(erc-tests--with-process-input-spy): Shadow
`erc--input-review-functions'.
(erc-check-prompt-input-for-excess-lines): Don't expect trailing
blanks to be trimmed.

* lisp/erc/erc-backend.el (erc--reject-unbreakable-lines): New
variable, an escape hatch for somewhat regaining pre-5.6
line-splitting behavior.
(erc--split-line): New utility function that doesn't rely on
column-oriented filling.
* lisp/erc/erc.el (erc--pre-send-split-functions): Append
`erc--split-lines' to value.
(erc--split-lines): New function to re-split current selection of
lines.
(erc-send-input): Hard-code line preparation instead of calling
`erc--pre-send-split-functions', in order to bake in traditional
behavior before move to "pre-splitting".
* test/lisp/erc/erc-scenarios-base-split-line.el: New file.
* test/lisp/erc/erc-tests.el (erc--split-line): New test.
(erc-send-current-line): Don't expect a flood argument when
interpreting a command because it's not passed along to the command's
handler.  This was previously misleading because it assigned undue
significance to something that had no bearing on the fate of a
command.
* test/lisp/erc/resources/base/flood/ascii.eld: New file.
* test/lisp/erc/resources/base/flood/koi8-r.eld: New file.

1630656770 Don't send multiline commands as messages in ERC
* lisp/erc/erc.el (erc-command-regexp): Relocate from further down in
same file.
(erc--check-prompt-input-for-multiline-command): Reject slash commands
containing multiple lines during input validation and before running
additional hooks.
(erc--discard-trailing-multiline-nulls): Don't mark input that begins
with a possible "slash command" as constituting a plain message just
because it has a trailing newline.  It's relatively easy to add a
newline by accident, which can result in the unintended sharing of a
command line.  Also, ERC already has a /SAY command that allows a user
to send a message starting a literal command.
* test/lisp/erc/erc-tests.el (erc-send-whitespace-lines): Fix test to
expect validation error when non-blank lines follow a slash command.

b0d761be0f Restore module var toggles in ERC's Custom buffers
* lisp/erc/erc-common.el (erc--neuter-custom-variable-state): Remove
function.  ERC famously toggles global minor-mode vars during normal
operations, which adds noise to its customization buffers because
`customize-variable-state' always sees an activated module's mode
variable as having "CHANGED".  To suppress this annoyance, a
workaround was employed that used a dishonest `:get' function to
simply return the "saved value," when present.  While this improved
the Customize experience, it also misled users, which likely wasn't
justified.
(erc--make-show-me-widget): Add helper to avoid forward declarations.
(erc--prepare-custom-module-type): Don't deprive users of a working
minor-mode toggle.
(erc--find-feature): New function to guess the feature of a module's
containing library.
(define-erc-module): Remove `:get' keyword.  Specify `:require'
instead, whose value may be nil.  Users who currently have mode vars
in their `custom-file' won't be impacted by this addition because
those `custom-set-variables' entries will still lack a REQUEST list
and hence won't incur a startup penalty.  And new users intent on
using the toggle will hopefully do so with the knowledge they're
opting in to requiring ERC on startup, which is not the case if they
follow the recommended practice of using `erc-modules' instead.
(erc-with-server-buffer): Inline `erc-server-buffer'.
* test/lisp/erc/erc-tests.el (erc-process-input-line): Use helper.
(define-erc-module--global): Change expected expansion.  (Bug#60935)

2e18ba6302 Simplify erc-button movement commands
* etc/ERC-NEWS: Mention TAB being bound to new command `erc-tab' and
`erc-previous-button' now stopping at the start of buttons.
* lisp/erc/erc-button.el (erc-button-mode, erc-button-enable,
erc-button-disable): Add and remove `erc-button-next' to
`erc--tab-functions' hook, which is tantamount to binding the command
in the read-only area of an ERC buffer.
(erc-button-next-function): Deprecate and remove from client code path
because this module doesn't concern itself with prompt input and thus
no longer needs to conform to the `completion-at-point-functions'
interface.
(erc-button--prev-next-predicate-functions): New variable, a hook to
determine whether to continue searching for a button.  Other modules
should utilize this as needed.
(erc-button--end-of-button-p): Add function to serve as default value
for `erc-button--continue-predicate'.
(erc--button-next): Add generalized button-movement function.
(erc-button-next, erc-button-previous): Make `erc-button-previous'
behave more predictably by having it land at the beginning of buttons.
And remove roundabout appeal to HOF in `erc-button-next'.
(erc-button-previous-of-nick): New command to jump to previous
appearance of nick at point.
* lisp/erc/erc-fill.el (erc-fill-wrap, erc-fill-wrap-enable,
erc-fill-wrap-disable): Add and remove merge-related hookee from
`erc-button--prev-next-predicate-functions'.
(erc-fill--wrap-merged-button-p): New function to detect redundant
speakers.
* lisp/erc/erc.el (erc-complete-functions): Quote TAB in doc string.
(erc-mode-map): Bind `erc-tab' to TAB.
(erc--tab-functions, erc-tab): Add new command and hook to serve as
unified dispatch for TAB-related operations.  It calls `c-a-p' in the
input area and defers to module code in the read-only message area.
* test/lisp/erc/erc-button-tests.el: New file.
* test/lisp/erc/erc-fill-tests.el (erc-fill-tests--wrap-populate): Run
finalizer for transient keymap timer.
* test/lisp/erc/erc-tests.el
(erc-button--display-error-notice-with-keys): Move to new dedicated
test file for erc-button and fix expected behavior of
`erc-button-previous'.  (Bug#62834)

5de90fa961 Extend erc-interactive-display to cover /JOINs
* lisp/erc/erc.el (erc-display): Mention that buffer-related display
options live in the customization group `erc-buffers'.
(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.  Also note related buffer-display options in
the doc string.
(erc-query-display, erc-interactive-display): Make the former an alias
of the latter, new in ERC 5.6, 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-reconnect-display): Use preferred name for cross-referencing
fallback option `erc-buffer-display' in doc string, and explain how
/reconnect handling differs.
(erc--setup-buffer-hook): Add new internal hook for modules that
operate on windows and frames, such as erc-speedbar and
erc-status-sidebar.
(erc-open): Run `erc--setup-buffer-hook' after `erc-setup-buffer' so
hook members know their code isn't tied to `erc-setup-buffer' itself,
which may be used in other contexts, but rather to a new ERC buffer on
which some display-related action has just been performed.
(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.
(erc-cmd-QUERY): Use preferred alias for `erc-query-display'.
* test/lisp/erc/erc-scenarios-base-buffer-display.el:
(erc-scenarios-base-buffer-display--interactive-default): New test.
* test/lisp/erc/erc-tests.el (erc-process-input-line,

default value of `erc-interactive-display' from `buffer' to
`window'.  (Bug#62833)

* lisp/erc/erc-button.el (erc-button-mode, erc-button-enable): Warn if
`erc-button-alist' contains deprecated FORM field in `nicknames'
entry.
(erc-button-alist): Discourage arbitrary sexp form for third item of
entries and offer more useful bounds-modifying function in its place.
Mention that anything other than `erc-button-buttonize-nicks' is
deprecated as the FORM field in a `nicknames' entry.  Bump
package-version even though this doesn't introduce a visible change in
the default value.
(erc-button--maybe-warn-arbitrary-sexp): Add helper for validating
third `erc-button-alist' field.
(erc-button--check-nicknames-entry): Add helper to check for
deprecated items in `erc-button-alist'.
(erc-button--preserve-bounds): Add function to serve as default value
for `erc-button--modify-nick-function).
(erc-button--modify-nick-function): Add new variable to hold a
function that filters nickname bounds when buttonizing.
(erc-button--phantom-users, erc-button--add-phantom-speaker,
erc-button--phantom-users-mode): Add new internal minor mode for
treating unseen speakers of PRIVMSGs as known members of the server
for things like coloring nicks during buffer playback.
(erc-button--get-user-from-speaker-naive): Add temporary utility
function to scrape nick from speaker in narrowed buffer.  This will be
replaced by an account-aware version in next major ERC release.
(erc-button-add-nickname-buttons): Accommodate function variant for
"form" field of `erc-button-alist' entries.  Minor optimizations.
This function will likely become the primary juncture for applying
text properties that support nickname-related user-intelligence
features.
(erc-button-add-buttons-1): Show warning when arbitrary sexp for third
"form" field encountered.  Accommodate binary function instead.
(erc-button--substitute-command-keys-in-region): Add helper function
for applying key substitutions in ERC warning messages.
(erc-button--display-error-notice-with-keys): Add new helper function
for displaying ad hoc warnings that possibly require key substitution.
(erc-button--display-error-notice-with-keys-and-warn): Add variant of
`erc-button--display-error-notice-with-keys' that also emits warnings.

d5435a0d82 Refactor marker initialization in erc-open
* lisp/erc/erc.el (erc--initialize-markers): New helper to ensure
prompt and its associated markers are set up correctly.
(erc-open): When determining whether a session is a logical
continuation, leverage the work already performed by the
`erc-networks' library to that effect.  Its verdicts are based on
network context and thus reliable even when a user dials anew from an
entry-point, which is not a simple reconnection because the user
expects a clean slate for everything except an existing buffer's
messages, meaning `erc--server-reconnecting' will be nil and
local-module state variables need resetting.  Also remove the check
for `erc-reuse-buffers' and instead trust that `erc-get-buffer-create'
always does the right thing.  Replace all code involving marker and
prompt setup by deferring to a new helper, `erc--initialize markers'.
* test/lisp/erc/erc-scenarios-base-local-module-modes.el: New file.

ba7fe88b78 Optionally prompt for more ERC entry-point params
* doc/misc/erc.texi: Update statement about availability of `:user'
keyword param when entry points called interactively.
* lisp/erc/erc/compat.el: Don't require `url-parse' when compiling.
Add forward declaration for `url-type'.
* lisp/erc/erc.el: Don't require `url-parse' when compiling.  Add
forward declarations for accessors of `url' struct from `url-parse'
library.
(erc-select-read-args): Allow optionally calling entry points with a
prefix arg to access params `user' and `:full-name'.
(erc-tls): Update doc string.
* test/lisp/erc/erc-tests.el (erc-select-read-args): Add test for
extra args.  (Bug#60428.)

(erc-interactive-display): Add new option to control display of server
buffers during interactive entry-point invocations.
(erc-select-read-args): Pass `erc-interactive-display' to entry
points.
* test/lisp/erc/erc-tests.el (erc-select-read-args): Expect
buffer-display values from `erc-interactive-display'.

0f7fc5cfdf Be smarter about switching to TLS from M-x erc
* lisp/erc/erc.el (erc--warn-unencrypted): Remove unused internal
function.
(erc-select-read-args): Offer to use TLS when user runs M-x erc and
opts for default server and port or provides the well-known IANA TLS
port or enters an ircs:// URL at the server prompt.  For the last two,
do this immediately instead of calling `erc-tls' interactively and
imposing a review of just-chosen values.  Also remove error warnings
and ensure `erc-tls' still works by setting
`erc-server-connect-function' to `erc-open-tls-stream' when
appropriate.  Include the word "URL" in server prompt.
(erc--with-entrypoint-environment): Add new macro for empowering an
entry point's interactive form to bind special variables in their
command's body without shadowing them in the lambda list.
(erc, erc-tls): Add internal keyword argument for interactive use, but
don't make it `keywordp' or advertise its presence.  Also use new
helper macro, `erc--with-entrypoint-environment', to temporarily bind
special vars given by interactive helper `erc-select-read-args'.
* test/lisp/erc/erc-tests.el (erc--with-entrypoint-environment): Add
new test.
(erc-select-read-args): Modify return values to expect additional
internal keyword argument where appropriate.
(erc-tls): Make assertions about environment.

9c65ac7365 Warn when customizing minor-mode vars for ERC modules
* lisp/erc/erc-common.el: (erc--inside-mode-toggle-p): Add global var
to inhibit mode toggles from being run by `erc-update-modules'.  It
must be non-nil inside custom-set functions for mode toggles created
by `define-erc-module'.
(erc--favor-changed-reverted-modules-state): Add new helper to show a
"SET" Custom state for `erc-modules' except when reverting to the
default value because \"STANDARD\" always takes precedence, as
explained somewhat in bug#12864.
(erc--assemble-toggle): Don't modify `erc-modules' when run from
custom-set function.
(erc--neuter-custom-variable-state): Add new function to serve as a
phony getter that deceives Customize into thinking the variable is
always set to its standard value.  The justification for this is that
toggling a module's minor mode in Customize has never worked and has
only sewn confusion in new users.  Without this hack, mode widgets
show a state of "CHANGED outside Customize", which alone is probably
preferable, except that they all end up toggled open, bringing them
unwanted attention and distracting the user.
(erc--tick-module-checkbox): Add helper to toggle the appropriate
checkbox in the `erc-modules' widget when a user interactively toggles
a minor-mode state variable.
(erc--prepare-custom-module-type): Create spec for minor-mode Custom
`:type', deferring various aspects until module-definition time.
(define-erc-module): Add `:get' and `:type' keywords to be passed to
`defcustom' definition for global modules.
* lisp/erc/erc.el (erc-modules): Inhibit `erc-update-modules' when run
from a minor-mode toggle's custom-set function.
* test/lisp/erc/erc-tests.el (define-erc-module--global,
define-erc-module--local): Update `erc-modules' mutations with
`erc--inside-mode-toggle-p' guard conditions.  (Bug#60935.)

0d3ccdbde4 Don't associate ERC modules with undefined groups
* lisp/erc/erc-capab.el: Add property crutch to help ERC find module's
Custom group.
* lisp/erc/erc-common.el (erc--find-group): Add new function, a helper
for finding an existing ERC module's Custom group based on
`define-erc-module' params.  Prefer `group-documentation' as a
sentinel over symbol properties owned by Customize because they might
not be present if the group isn't yet associated with any custom
variables.
(define-erc-module): Set `:group' keyword value more accurately,
falling back to `erc' when no associated group has been defined.
* test/lisp/erc/erc-tests.el (erc--find-group, erc--find-group--real):
New tests.
(define-erc-module--global, define-erc-module--local): Expect the
`:group' keyword to be the unevaluated `erc--find-group'
form.  (Bug#60935.)

2d876a4ca9 Convert ERC's Imenu integration into proper module
* lisp/erc/erc-goodies.el: Don't add Imenu hooks to `erc-mode-hook' at
top level.  Remove autoload for `erc-create-imenu-index' because it
already exists in the `erc-imenu' library.
(erc-imenu-setup): Move to the erc-imenu library.
* lisp/erc/erc-imenu.el (erc-unfill-notice): Allow modifications to
read-only text.  Thanks to Yusef Aslam for reporting this bug.
(erc-imenu-setup): Move here from goodies.
(erc-imenu--create-index-function): New helper var to hold previous
local value of `imenu-create-index-function'.  Perhaps advice should
be used instead, but a cursory search of the Emacs code base reveals
no such usage.
(erc-imenu-mode, erc-imenu-enable, erc-imenu-disable): Create "new"
ERC module for Imenu integration.
* lisp/erc/erc.el (erc-modules): Add `imenu' to default value and
create widget menu item.  Update package-version.
* test/lisp/erc/erc-tests.el (erc-tests--modules): Add
`imenu'.  (Bug#60954)

9aa2806fdc Modify erc-mode-map in module definitions
* lisp/erc/erc-button.el (erc-button-mode, erc-button-enable,
erc-button-disable): Replace call to `erc-button-setup' with one to
`erc--modify-local-map'.  This means `erc-button-setup' is now dead
code from a client perspective.
* lisp/erc/erc-goodies.el (erc-irccontrols-enable,
erc-irccontrols-disable, erc-irccontrols-mode): Bind
`erc-toggle-interpret-controls' in module definition so it's only
available when the module is active.
* lisp/erc/erc-log.el (erc-log-mode, erc-log-enable, erc-log-disable):
Move top-level `define-key' into module definition.
* lisp/erc/erc-match.el (erc-match-mode, erc-match-enable,
erc-match-disable): Move top-level `define-key' into module
definition.
* lisp/erc/erc.el (erc-mode-map): Remove C-c C-c binding for
`erc-toggle-interpret-controls'.
(erc--modify-local-map): Add helper for global modules to use when
modifying `erc-mode-map'.
* test/lisp/erc/erc-tests.el (erc--modify-local-map): Add test.
Ensure modifications to `erc-mode-map' on loading `erc' and via
`erc-mode-hook' still work.  (Bug#60954.)

3d81ecf0a9 Leverage loaddefs for migrating ERC modules
* lisp/erc/erc-common.el (erc--features-to-modules,
erc--modules-to-features, erc--module-name-migrations): Remove unused
internal functions.
(erc--normalize-module-symbol): Make aware of new migration scheme
based on symbol properties.
* lisp/erc/erc-page.el: Add autoload cookie for module migration.
* lisp/erc/erc-pcomplete.el: Add autoload cookies for module
migration.
* lisp/erc/erc-services.el: Add autoload cookie for module migration.
* lisp/erc/erc-sound.el: Add autoload cookie for module migration.
* lisp/erc/erc-stamp.el: Add autoload cookie for module migration.
* lisp/erc/erc.el (erc-modules): Reorder default value, sorted by
`string<' so that Customize does not consider the value to have been
edited.  Remove non-existent module `hecomplete' from lineup and swap
a couple more to maintain sorted order.  Change `:initialize' function
to tag all symbols for built-in modules with an `erc--module'
property.  In the `:set' function, ensure third-party modules appear
after the sorted and normalized built-ins, but in user-defined order.
Do this to prevent all modules, built-ins included, from ending up as
populated form fields for the "other" checkbox in the Customize
interface.
(erc--find-mode): Add helper function for `erc--update-modules'.
(erc--update-modules): Always resolve module names and only
conditionally attempt to require corresponding features.
* test/lisp/erc/erc-tests.el (erc-tests--modules): Add manifest for
asserting built-in modules and features.  This is easier to verify
visually than looking at the custom-type set for `erc-modules'.
(erc-modules--initialize): New test.
(erc-modules--internal-property): Add test.
(erc--normalize-module-symbol): New test.
(erc--find-mode): New test.
(erc--update-modules) Adapt to new paradigm and make more
comprehensive.  (Bug#60954.)

db7096a532 Yield to erc-move-to-prompt before unhiding prompt
* lisp/erc/erc-backend.el (erc--hide-prompt): Change hook depth from 0
to 91 to allow the `move-to-prompt' module to do its thing.  This
feature was added by bug#54826 and first appeared in Emacs 29.
* lisp/erc/erc-common.el (erc-server-user): Remove erroneous comment.
The `buffers' field is a list of buffers.
* test/lisp/erc/erc-tests.el (erc-hide-prompt): Use `erc--target'
instead of `erc-default-recipients' because this is new code.

183e749270 Don't preserve non-module minor modes in erc-open
* lisp/erc/erc-common.el (define-erc-module): Add symbol property
`erc-module' to minor modes defined as part of a module.
* lisp/erc/erc.el (erc--merge-local-modes): Be more conservative when
persisting local minor-mode state across ERC sessions.  User and
third-party modes that were not defined via `define-erc-modules'
should be left alone.
(erc-open): Run major-mode hooks and enable minor modes after prompt
has been set up.  This ensures that module-setup code can access a
fully initialized `erc-input-marker'.
* test/lisp/erc/erc-tests.el (erc--merge-local-modes): Add mocks for
`erc-module' symbol property and a test case covering some foreign ERC
mode.
(define-erc-module--global, define-erc-module--local): Expect the
`erc-module' symbol property to be defined for mode symbols and
aliases.  (Bug#60784.)

ff35ac9dfa Fix default-port regression in erc-select-read-args
* lisp/erc/erc.el (erc--warn-unencrypted): New function, likely
temporary, to warn new users connecting interactively to the default
server, "irc.libara.chat", via the default non-TLS port, 6667.
(erc-select-read-args): Remove stray code from incomplete feature
introduced by bug#56514.  Ensure connecting always works with default
port, which is non-TLS.  Respect `erc-prompt-for-password' when user
pastes URL containing password component into "server" prompt.  Maybe
add `erc--warn-unencrypted' as one-off hook for impending connection.
* test/lisp/erc/erc-tests.el (erc-select-read-args): Always expect
password prompt and sometimes a non-TLS port when `erc' called
interactively.  (Bug#60428.)

interactive code should be an uppercase "P".

interval.
* lisp/erc/erc.el (erc-casemapping--rfc1459-strict,
erc--casemapping-rfc1459): Make these case tables instead of
translation tables.  The functions in case-table.el modify the
standard syntax table, but that doesn't seem to make sense here,
right?
* test/lisp/erc/erc-tests.el (erc-downcase): Add cases showing

(erc--debug-irc-protocol-mask-secrets): Add variable to indicate
whether to mask passwords in debug logs.
(erc--mask-secrets): New function to swap masked secret with question
marks in debug logs.
(erc-log-irc-protocol): Conditionally mask secrets when
`erc--debug-irc-protocol-mask-secrets' is non-nil.
(erc--auth-source-search): Don't unwrap secret from function before
returning.
(erc-server-join-channel, erc-login): Use `erc--unfun'.

Support local ERC modules in erc-mode buffers
* doc/misc/erc.texi: Mention local modules in Modules chapter.

* etc/ERC-NEWS: Mention changes to `erc-update-modules'.

* lisp/erc/erc.el (erc-migrate-modules): Add some missing mappings.
(erc-modules): When a user removes a module, disable it and kill its
local variable in all ERC buffers.
(erc-update-modules): Move body of `erc-update-modules' to new
internal function.
(erc--update-modules): Add new function, a renamed and slightly
modified version of `erc-update-modules'.  Specifically, change return
value from nil to a list of minor-mode commands for local modules.
Use `custom-variable-p' to detect flavor.
(erc--merge-local-modes): Add helper for finding local modules
already active as minor modes in an ERC buffer.
(erc-open): Replace `erc-update-modules' with `erc--update-modules'.
Defer enabling of local modules via `erc--update-modules' until after
buffer is initialized with other local vars.  Also defer major-mode
hooks so they can detect things like whether the buffer is a server or
target buffer.  Also ensure local module setup code can detect when
`erc-open' was called with a non-nil `erc--server-reconnecting'.

* lisp/erc/erc-common.el (erc--module-name-migrations,
erc--features-to-modules, erc--modules-to-features): Add alists of
old-to-new module names to support module-name migrations.
(erc--assemble-toggle): Add new helper for constructing mode toggles,
like `erc-sasl-enable'.
(define-erc-modules): Defer to `erc--assemble-toggle' to create toggle
commands.
(erc--normalize-module-symbol): Add helper for `erc-migrate-modules'.
