f109396fe3 Prefer erc-target to erc-default-target
* etc/ERC-NEWS: Mention `erc-target' and new `erc-server-buffer-p'
alias.
* lisp/erc/erc-backend.el (erc-process-sentinel): Set `joined-p' slot
of `erc--target-channel' object to nil when applicable.
(erc-server-JOIN): Mark `erc--target-channel' object as being joined.
* lisp/erc/erc-common.el (erc--target-channel): Add `joined-p' slot.
Use hyphenated name so accessor function's name ends in "joined-p"
rather than "joinedp".  Note that this will always be nil when
disconnected.
(erc--target): Relocate here from erc.el.
(erc-target): New public API function to return the current buffer's
target as a string, even in channels that have been unjoined.
* lisp/erc/erc-networks.el (erc--default-target): Remove forward
declaration.
(erc-networks--id-reload): Use `erc-target' instead of
`erc--default-target' as predicate for visiting target buffers.
* lisp/erc/erc.el (erc-remove-channel-users): Set channel "joinedness"
to nil in `erc--target-channel' object, when applicable.
(erc--target): Move to erc-common.
(erc--default-target): Remove, replaced by new function `erc-target'.
(erc-query-buffer-p): Use `erc-target'.
(erc-after-connect): Revise doc string.
(erc-connection-established): Revise doc string and move
`erc-unhide-query-prompt' business before hook.
(erc--current-buffer-joined-p): Remove comment and use new `joined-p'
slot of `erc--target-channel' for determining "joinedness" of channel.
(erc-kill-buffer-function): Use `erc--target-channel-p' for detecting
whether the buffer is a channel buffer.
* test/lisp/erc/erc-networks-tests.el
(erc-networks--shrink-ids-and-buffer-names--hook-collapse-target):
Remove comment.
* test/lisp/erc/erc-scenarios-base-reuse-buffers.el
(erc-scenarios-common--base-reuse-buffers-channel-buffers):
Clarify assertion.
* test/lisp/erc/erc-tests.el (erc-with-all-buffers-of-server):
Replace `erc-default-recipients' with `erc--target'.
(erc--target-from-string): Update expected shape of
`erc--target-channel' struct with new `joined-p' slot.
(erc-message): Set `erc--target' in buffer "#chan".  (Bug#66578)

8cf66ab1e5 Rename erc-server-buffer-p
* lisp/erc/erc-log.el (erc-log-all-but-server-buffers): Use
`erc--server-buffer-p' instead of `erc-server-buffer-p'.  This
replacement is presumed to be relatively "safe" because this function
is unused in the code base and only appears in the doc string for the
option `erc-enable-logging'.
* lisp/erc/erc-match.el (erc-match-message): Leave comment proposing
that `erc--server-buffer-p' should be preferred to
`erc-server-buffer-p'.  Use preferred alias for `erc-server-buffer-p'.
* lisp/erc/erc-notify.el (erc-cmd-NOTIFY): Use preferred alias for
`erc-server-buffer-p', and leave FIXME comment.
* lisp/erc/erc-speedbar.el (erc-speedbar-buttons): Use
`erc--server-buffer-p' instead of `erc-server-buffer-p'.  The logic
here seems simple enough to justify a change, however the absence of
related bug reports is perhaps an argument against this.
* lisp/erc/erc-track.el (erc-track-modified-channels): Use preferred
alias for `erc-server-buffer-p' and leave comment noting possible bug.
* lisp/erc/erc.el (erc-once-with-server-event): Use
`erc--server-buffer-p' instead of `erc-server-buffer-p'.  This change
seems justified because the function sets local hooks that would
otherwise be ignored outside of a server buffer.
(erc-server-buffer-p, erc-server-or-unjoined-channel-buffer-p): Make
the former an obsolete alias for the latter.
(erc--server-buffer-p): New function to replace `erc-server-buffer-p'
internally in new code.  Unlike its predecessor, it returns nil in
parted and kicked channels.
(erc-open-server-buffer-p): Use `erc--server-buffer-p' instead of
`erc-server-buffer-p'.  Given the name and the doc string, breaking
the odd misuse of this function in parted buffers seems justified
because this is clearly a bug fix.  Also, all uses in-tree conform to
the intended behavior as documented.  And a cursory grep of all "erc-"
prefixed packages on MELPA reveals zero instances of this function.
Nor is it used in erbot.
(erc-get-buffer): Mention behavior in doc string regarding parted and
kicked-from channels.
(erc-cmd-GQUIT): Fix wrong-number-of-arguments bug in timer function.
(erc-default-target): Mention behavior regarding unjoined channels.
(erc-kill-query-buffers): Don't use `erc-server-buffer-p'.  This
replacement may break third-party code expecting to leave parted
channels behind, but it seems sane when considering only the lone
internal use in `erc-cmd-QUIT'.
; * test/lisp/erc/resources/join/network-id/foonet.eld: Timeouts.

bcebda5eec Respect user markers in erc-insert-timestamp-left
* lisp/erc/erc-stamp.el (erc-insert-timestamp-left): Convert to normal
function, a mere wrapper that defers to existing generic variants, in
order to dissuade users from adding their own methods, which could
complicate troubleshooting, etc.
(erc--insert-timestamp-left): Rename both methods using internal
double-hyphen convention.  In `erc-stamp--display-margin-mode'
implementation, don't displace third-party markers.
* test/lisp/erc/erc-scenarios-stamp.el: New file.  (Bug#60936)

47612514a9 Fix right-sided stamps commingling with erc-prompt
* lisp/erc/erc-stamp.el (erc-insert-timestamp-left-and-right): Fix bug
that saw the prompt being inserted after messages but just inside the
narrowed operating portion of the buffer, which meant remaining
modification hooks would see it upon visiting.  Thanks to Corwin Brust
for catching this.
* test/lisp/erc/erc-fill-tests.el (erc-fill-wrap--monospace): Use
custom `erc-prompt' function to guarantee invariants asserted by
`erc--assert-input-bounds' are preserved throughout.  (Bug#60936)

7ffc79690a Restore missing metadata props in erc-display-line
* etc/ERC-NEWS: Designate `erc-display-message' as the favored means
of inserting messages.
* lisp/erc/erc-fill.el (erc-fill-wrap): Skip any `unknown' `erc-msg'.
* lisp/erc/erc-stamp.el (erc-stamp--current-time): Use an existing
`erc-ts' text property, when present, for the current message time.
* lisp/erc/erc.el (erc-display-line-1, erc-insert-line): Update doc
string and declare the former an obsolete alias for the latter,
`erc-insert-line'.  Have `erc-log' label say `erc-display-message'
even though this function is actually `erc-insert-line'.
(erc-display-line): Convert to a thin wrapper around
`erc-display-message', and move its existing body to a new internal
function, `erc--route-insertion'.
(erc--route-insertion): Adopt former body of `erc-display-line', now a
convenience wrapper around `erc-display-message'.  Copy
`erc--msg-props' hash table when inserting a message in multiple
buffers.  At present, only `erc-server-QUIT' uses this facility, so
such a move shouldn't impact performance in any measurable way.  Also,
improve readability with at most one recursive call for the
fall-through case.
(erc--compose-text-properties, erc--merge-text-properties-p): Rename
former to latter to avoid confusion with `composition' property.
(erc-display-message): Update doc string.  Attempt to adapt a non-nil
TYPE parameter for use as the value of the `erc-msg' text property
before resorting to a value of `unknown'.  But only do this when
PARSED is nil, and MSG is a string.  Call `erc--route-insertion'
instead of `erc-display-line'.  Use new name for
`erc--compose-text-properties'.
(erc-put-text-property): Update name of variable
`erc--compose-text-properties'.
* test/lisp/erc/erc-networks-tests.el (erc-networks--set-name): Mock
`erc--route-insertion' instead of `erc-display-line'.
* test/lisp/erc/erc-scenarios-display-message.el: New file.
* test/lisp/erc/erc-tests.el (erc--route-insertion): New test.
* test/lisp/erc/resources/base/display-message/multibuf.eld: New test
data.

52af0a5fb9 Add command to refill buffer in erc-fill-wrap-mode
* lisp/erc/erc-fill.el (erc-fill-function, erc-fill-wrap-mode):
Mention new command `erc-fill-wrap-refill-buffer' in doc string.
(erc-fill--wrap-rejigger-last-message): New internal variable.
(erc-fill--wrap-rejigger-region, erc-fill-wrap-refill-buffer): New
command and helper function for fixing alignment issues that arise,
for example, from adjusting pixel-display widths of buffer text during
a session.
* test/lisp/erc/erc-fill-tests.el (erc-fill-tests--simulate-refill):
New function for approximating `erc-fill-wrap-refill-buffer'.
(erc-fill-wrap--merge): Assert refilling is idempotent.  (Bug#60936)

5e2be1e0ba Swap hook positions of erc-fill and erc-match-message
* etc/ERC-NEWS: Fix new order of reserved modify-hook members.
* lisp/erc/erc-fill.el: Increase depth of `erc-fill' in both modify
hooks from 40 to 60.
* lisp/erc/erc-match.el (erc-match-mode, erc-match-enable,
erc-match-disable): Use general module setup function
`erc-match--setup' for buffer-local modifications instead of calling
`erc-match--modify-invisibility-spec' directly.  Add and remove new
post-modify hook `erc-match--on-insert-post'.
(erc-hide-fools): Use `erc--msg-props' for communicating to
post-processing step for applying invisible props instead of doing so
immediately.
(erc-match--on-insert-post): New function to apply module-specific
`invisible' props.  Will likely be replaced by a general service to do
the same, perhaps provided by a future "erc-ignore"-like module.
(erc-match--modify-invisibility-spec, erc-match--setup): Rename former
to latter and only operate on current buffer.
* test/lisp/erc/erc-scenarios-match.el
(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
expected order of ERC-owned `invisible' prop members `match-fools' and
`timestamp'.
* test/lisp/erc/erc-tests.el (erc--essential-hook-ordering): Swap
expected order of `erc-fill' and `erc-add-timestamp' in both hooks.

c68dc7786f Manage some text props for ERC insertion-hook members
* etc/ERC-NEWS: Mention that ERC only adds the text property
`cursor-sensor-functions' when `erc-echo-timestamps' is enabled.  Also
mention that date stamps are now inserted as separate messages.
* lisp/erc/erc-fill.el (erc-fill): Look for text prop `erc-cmd'
instead of `erc-command' and use helper utility to do so.
(erc-fill-static): Skip date stamps because this fill style leaves
them flush left.
(erc-fill-wrap-mode, erc-fill-wrap-enable, erc-fill-wrap-disable):
Don't hook on the soon-to-be-removed function interface
`erc-stamp--insert-date-function' because date stamps are now separate
messages.
(erc-fill--wrap-continued-message-p): Restore accidentally discarded
doc string.  Derive context about current message from text props at
`point-min', and use updated property names and utility functions.
Abort when previous message is now hidden.
(erc-fill--wrap-stamp-insert-prefixed-date): Remove unused function,
originally meant to be new in ERC 5.6, and move logic for date-stamp
measuring portion directly to `erc-fill-wrap' itself.
(erc-fill--wrap-measure): New helper function.
(erc-fill-wrap): Use helper `erc-fill--wrap-measure' and incorporate
date-stamp detection and width measuring from removed helper.  Don't
dedent first word for messages of unknown origin, such as those
inserted by `erc-display-line' alone without prior preparation from
`erc-display-message'.
* lisp/erc/erc-goodies.el (erc-readonly-mode, erc-readonly-enable):
Set hook depth explicitly to 70.
* lisp/erc/erc-stamp.el (erc-timestamp-format-left): Mention that a
trailing newline is implicit if not provided and that users who don't
want date stamps should use `erc-timestamp-format-right' instead.
(erc-stamp-mode, erc-stamp-enable): Call `erc-stamp--setup' instead
of `erc-munge-invisibility-spec', and bump hook depth for
`erc-add-timestamp' to 70.
(erc-stamp--current-time): Use `erc-ts' instead of `erc-timestamp'
text property in doc string.
(erc-stamp--skip): New internal variable.
(erc-stamp--allow-unmanaged): New variable for legacy code to force
`erc-add-timestamps' to run when `erc--msg-props' is nil.
(erc-add-timestamp): Always run when `erc-stamp--allow-unmanaged' is
non-nil unless `erc-stamp--skip' is as well because the latter takes
precedence.  Don't add `erc-ts' text prop directly unless
`erc-stamp--allow-unmanaged is non-nil.  Instead, use the new
`erc--msg-props' facility to defer until after modification hooks.
Likewise, don't add `cursor-senor-functions' directly either unless
the same compatibility flag is enabled.  Instead, expect the latter to
be handled by a post-modify hook conditioned on the option
`erc-echo-timestamps'.
(erc-timestamp-last-inserted-left): Mention that the final trailing
newline specified in the format string no longer appears in the
recorded value.
(erc-stamp-prefix-log-filter): Use updated name for timestamp
property as well as helper utility for accessing it.
(erc-stamp--inherited-props): Add doc string.
(erc-insert-timestamp-right): Fix bug involving object cycle where
the time-stamp string would appear in its own `display' property.
(erc-stamp--insert-date-function, erc-stamp--insert-date-hook): Remove
unused internal function-valued interface variable and replace with
the latter, a normal hook.
(erc-stamp--date-format-end, erc-stamp--propertize-left-date-stamp):
New function and auxiliary variable to apply date stamp properties at
the post-modify stage.  Add text property `erc-stamp-type' to inserted
date stamps to help folks distinguish between them and other
left-sided stamps.
(erc-stamp--current-datestamp-left,
erc-stamp--format-date-stamp,
erc-stamp--insert-date-stamp-as-phony-message,
erc-stamp--lr-date-on-pre-modify): New functions and state variable to
help ERC treat date stamps as separate messages while working within
the established mechanism for processing inserted messages.  Shadow
`erc-stamp--invisible-property' when calling `erc-format-timestamp' in
order to prevent date stamps from inheriting other `invisible' props.
These date stamps are special in that they have no business being
hidden along with the current message.
(erc-insert-timestamp-left-and-right): On initial run in any buffer,
remember whether the date stamp needed newline massaging on insertion.
Move all business for inserting date stamps to post-modify hooks, but
run them forcibly if this is the very first date stamp in the current
buffer.  Also mention some specifics related to relevant text props in
the doc string.
(erc-format-timestamp): Don't add `invisible' prop to stamp unless
`erc-stamp--invisible-property' is non-nil.
(erc-stamp--csf-props-updated-p): New local variable.
(erc-munge-invisibility-spec): Restore `cursor-sensor-functions' text
property for existing messages when a user enables the option
mid-session.  Add and remove hooks for use with automatic timestamp
echoing.
(erc-stamp--add-csf-on-post-modify): New function to add
`cursor-sensor-functions' property on post-modify hooks.
(erc-stamp--setup): Perform some additional teardown.
(erc-stamp--on-clear-message): Look for text property `erc-ts' instead
of `erc-timestamp'.
(erc-echo-timestamp, erc--echo-ts-csf): Use utility to find time-stamp
text prop in current message.
(erc-stamp--update-saved-position, erc-stamp--reset-on-clear): Use
hook `erc-stamp--insert-date-hook' instead of excised function-valued
variable interface `erc-stamp--insert-date-function'.
* lisp/erc/erc-truncate.el (erc-truncate-buffer-to-size): Use internal
utility to find beginning of message.
* lisp/erc/erc.el (erc--msg-props, erc--msg-props-overrides): New
internal variables for initializing and conveying metadata-oriented
text properties among insert and send hooks.
(erc-insert-modify-hook): Mention reserved depth ranges for built-in
members in doc string.
(erc-send-action):  Use convenience variable to modifying text props
instead of awkwardly overriding `erc-insert-pre-hook'.
(erc--check-msg-prop, erc--get-inserted-msg-bounds,
erc--get-inserted-msg-prop, erc--with-inserted-msg,
erc--traverse-inserted): New utility functions and macros to help
modules find metadata and message-delimiting text props.
(erc-display-line-1): Ensure the first character of every message in
an ERC buffer has the `erc-msg' property, as well as any other props
in `erc--msg-props', when populated.
(erc--hide-message): Don't bother offsetting start of first message in
a buffer.
(erc--ranked-properties, erc--order-text-properties-from-hash): New
variable and function to convert `erc--msg-props' into a plist
suitable for `add-text-properties'.
(erc-display-message): Make doc string more informative.  Bind and
initialize `erc--msg-props' for use by all hooks.  Respect
`erc--msg-prop-overrides' when non-nil.  Don't add `erc-command'
property.  Instead, ensure `erc--msg-props' contains an `erc-cmd' item
when the parameter PARSED is non-nil.
(erc--own-property-names): Add `erc-stamp-type'.
(erc--get-speaker-bounds): Use helper to find message start.
(erc-process-ctcp-query, erc-send-current-line): Use convenience
variable to leverage framework for manipulating message metadata
instead of overriding `erc-insert-pre-hook'.
(erc-display-msg): Bind `erc--msg-props' for use by all send-related
hooks.  Add text props from table after `erc-send-post-hook'.
(erc-restore-text-properties): Improve doc string.
(erc--get-eq-comparable-cmd): Use `if-let' instead of `if-let*'.
* test/lisp/erc/erc-fill-tests.el (erc-fill-tests--insert-privmsg):
Make phony message more realistic.
(erc-fill-tests--wrap-populate): Shorten overlong line.
(erc-fill-tests--wrap-check-prefixes): Make test utility more vigilant
in asserting no gaps exist in `line-prefix' property interval.
(erc-fill-tests--compare): Compare text props on text-prop values that
are themselves strings.
* test/lisp/erc/erc-scenarios-log.el (erc-scenarios-log--clear-stamp):
Ensure `erc-stamp' is loaded.
* test/lisp/erc/erc-scenarios-match.el
(erc-scenarios-match--stamp-left-current-nick,
erc-scenarios-match--invisible-stamp): Use `default-value' for
`erc-insert-modify-hook' in ordering assertion.
(erc-scenarios-match--find-bol, erc-scenarios-match--find-eol): Remove
unused assertion helper functions.
(erc-scenarios-match--stamp-right-fools-invisible): Remove misplaced
ERT tag from function and use utility to find message bounds.
(erc-scenarios-match--stamp-right-fools-invisible): Use real utility
from main library to find message end.
(erc-scenarios-match--fill-wrap-stamp-dedented-p): New assertion
utility function.
(erc-scenarios-match--hide-fools/stamp-both/fill-wrap) New test.
(erc-scenarios-match--hide-fools/stamp-both/fill-wrap/speak): New
test.
(erc-scenarios-match--stamp-both-invisible-fill-static): Expect
`erc-cmd' at beginning of inserted message's filled line, even if the
line starts with white space.  Also, add new function parameter
`assert-ds', a callback to run when visiting the second date stamp,
which is followed by a hidden message.  In the test of the same name,
expect the date stamp's invisibility interval to begin at the newline
after the previous message and to not contain any existing
invisibility props, namely, those belonging to the subsequent hidden
"fools" message.  Also use shortened "metadata" text prop names.
(erc-scenarios-match--stamp-both-invisible-fill-static--nooffset):
Expect the date stamp's invisibility interval to match its field's
instead of starting and ending sooner.
* test/lisp/erc/erc-stamp-tests.el: Put well-known metadata prop at
the start of the message.
* test/lisp/erc/erc-tests.el (erc--refresh-prompt): Prevent modules
from mutating hooks.
(erc--order-text-properties-from-hash, erc--check-msg-prop): New
tests.

d46c016fbd Sort and dedupe when loading modules in erc-open
* doc/misc/erc.texi: Add new subheading "Module Loading" under the
"Modules" chapter.
* lisp/erc/erc.el (erc--sort-modules): New utility function to sort
and dedupe modules.
(erc-modules): In `custom-set' function, factor out collation into
separate utility `erc--sort-modules'.
(erc-update-modules): Call `erc--update-modules' with an argument, the
current value of `erc-modules'.
(erc--aberrant-modules): New variable, a list of symbols whose modules
ERC suspects of being incorrectly defined.
(erc--warn-about-aberrant-modules): New function to print an error
message and emit a warning prior to connecting when
`erc--aberrant-modules' is non-nil.
(erc--find-mode): Make heuristic more robust by always checking for a
mode activation command rather than just a state variable.  This fixes
a compatibility bug, new in 5.6, affecting third-party modules that
autoload module definitions instead of their corresponding
mode-activation commands.
(erc--update-modules): Add new positional argument `modules'.
(erc--setup-buffer-hook): Add new default member,
`erc--warn-about-aberrant-modules'.
(erc-open): Pass sorted `erc-modules' to `erc--update-modules'.
* test/lisp/erc/erc-tests.el (erc--sort-modules): New test.
(erc-tests--update-modules): New fixture.
(erc--update-modules): Remove and rework as three separate tests
dedicated to specific contexts.  The existing one had poor coverage
and was difficult, if not impossible, to follow.
(erc--update-modules/unknown, erc--update-modules/local,
erc--update-modules/realistic): New tests.  (Bug#57955)

9120d7a32e Honor nil values in erc--restore-initialize-priors
* lisp/erc/erc.el (erc--restore-initialize-priors): Don't produce
invalid "empty" `setq' form when parameter VARS contains defaults that
initialize to nil.  This function is mainly used by local modules,
which were first made usable in ERC 5.5 (bug#57955).
* test/lisp/erc/erc-tests.el (erc--restore-initialize-priors): Fix
expected expansion, which is now slightly leaner.  (Bug#60936)

328a985651 Skip post-minibuffer restore in erc-scrolltobottom-all
* etc/ERC-NEWS: Remove mention of `erc-scrolltobottom-relaxed' in
entry for module `scrolltobottom'.
* lisp/erc/erc-goodies.el (erc-input-line-position): Fix mention of
abandoned option `erc-scrolltobottom-relaxed'.
(erc-scrolltobottom-all): Subsume option `erc-scrolltobottom-relaxed'
by recognizing a third value state, `relaxed'.  A separate option
would make more sense if other options also depended on
`erc-scrolltobottom-all'.
(erc-scrolltobottom-relaxed): Remove redundant option, which was to be
new in ERC 5.6.
(erc-scrolltobottom-enable, erc-scrolltobottom-mode): Warn if user
attempts to enable `erc-scrolltobottom-all' on Emacs 27, which is not
supported.
(erc--scrolltobottom-relaxed-commands,
erc--scrolltobottom-post-force-commands,
erc--scrolltobottom-relaxed-skip-commands): Remove unused variables.
(erc--scrolltobottom-on-pre-command,
erc--scrolltobottom-on-pre-command-relaxed,
erc--scrolltobottom-on-post-command-relaxed): Remove unused functions.
(erc--scrolltobottom-on-post-command): Remove conditional branch for
dealing with a non-nil `erc--scrolltobottom-window-info'.
(erc--scrolltobottom-setup): Convert from generic to normal function
and remove setup and teardown for unused hooks.  Set variable
`read-minibuffer-restore-windows' locally when option
`erc-scrolltobottom-all' is non-nil.
(erc--scrolltobottom-on-pre-insert): Replace reference to subsumed
option `erc-scrolltobottom-relaxed' with new value `relaxed' for
existing option `erc-scrolltobottom-all'.
* test/lisp/erc/erc-scenarios-scrolltobottom-relaxed.el
(erc-scenarios-scrolltobottom--relaxed): Replace option

3979f83cd6 Inhibit slash commands in erc--input-review-functions
* lisp/erc/erc.el (erc--input-review-functions): Add new review
function `erc--inhibit-slash-cmd-insertion'.
(erc--check-prompt-input-functions): Move
`erc--check-prompt-input-for-multiline-command' above
`erc--check-prompt-input-for-multiline-blanks'.
(erc--inhibit-slash-cmd-insertion): New "review" function to suppress
insertion of prompt input for slash commands.  Doesn't affect "meta"
slash commands like /SAY.
(erc--send-input-lines): Don't bother checking whether message is a
command.  Instead, trust verdict handed down by message-prep and
review functions.  This opens the door to optional insertion for
debugging purposes or when echoing command lines in a shell-like
fashion.
* test/lisp/erc/erc-tests.el (erc-send-whitespace-lines): clean up

a3c6ed0e36 Improve erc-warn-about-blank-lines behavior
* etc/ERC-NEWS: Mention more detailed feedback when option
`erc-warn-about-blank-lines' is non-nil.
* lisp/erc/erc-common.el (erc--input-split): Add `abortp' slot to
allow a premature exit while validating prompt input.
* lisp/erc/erc.el (erc-warn-about-blank-lines): Clarify meaning of
"blank lines" in doc string, and mention interaction with
companion option `erc-send-whitespace-lines'.
(erc-inhibit-multiline-input): Fix inaccurate description in doc
string.
(erc--input-review-functions): Move
`erc--discard-trailing-multiline-nulls' to end of list, after
`erc--run-input-validation-checks' so that the latter doesn't have to
resplit the original input string in order to issue feedback.
(erc--blank-in-multiline-input-p): Remove unused internal function
originally slated to be part of ERC 5.6.
(erc--check-prompt-input-for-something): New trivial validation
function to check if the input is empty.
(erc--count-blank-lines): New function that tallies up the number of
blank and whitespace-only lines in the current input.  One downside of
this design is that this function's conclusions aren't shared with
`erc--discard-trailing-multiline-nulls', which must decide on its own
how many lines to strip.
(erc--check-prompt-explanation): New variable.
(erc--check-prompt-input-for-multiline-blanks): Rework significantly
to provide more informative messages and more sensible behavior for
common cases with respect to relevant option values.
(erc--check-prompt-input-functions): Add new validation function
`erc--check-prompt-for-something'.
(erc--run-input-validation-checks): Set `abortp' slot of
`erc--input-split' when hooks return a non-string, rather than
generate an unhelpful fallback message.  Also print a message when
the variable `erc--check-prompt-explanation' is non-nil.
(erc-send-current-line): When the `abortp' slot of the current
`erc--input-split' object is non-nil, forgo normal input processing.
This fixes a regression in 5.6-git, which previously emitted an error
message when it should have just exited the command.
(erc--discard-trailing-multiline-nulls): Always run, regardless of
`erc-send-whitespace-lines', and leave a blank line behind when
stripping a message consisting of only blank lines.
(erc--run-send-hooks): Always run hooks and surrounding logic rather
than only when hooks are populated.
* test/lisp/erc/erc-tests.el (erc--refresh-prompt): Add assertion and
use default value for `erc--input-review-functions'.
(erc-ring-previous-command): Use default value for
`erc--input-review-functions' and ensure `erc-current-nick' does not
error.
(erc--blank-in-multiline-input-p): Remove obsolete test.
(erc--check-prompt-input-functions): Update expected message.
(erc--discard-trailing-multiline-nulls, erc--count-blank-lines): New
tests.
(erc-tests--check-prompt-input--expect,
erc-tests--check-prompt-input-messages): New helper variables.
(erc--check-prompt-input-for-multiline-blanks,
erc--check-prompt-input-for-multiline-blanks/explanations): New tests.
(erc-send-whitespace-lines): Expect hook-processing logic to pad empty
lines instead of deferring to `erc-send-input-line-function'.

`pre-command-hook' from 91 to 80.
* lisp/erc/erc-goodies.el (erc-input-line-position): Mention secondary
role when new option `erc-scroll-to-bottom-relaxed' is non-nil.
(erc-scrolltobottom-all): New option that decides whether module
`scrolltobottom' affects all windows or just the selected one, as it
always has.
(erc-scrolltobottom-relaxed): New option to leave the prompt
stationary instead of forcing it to the bottom of the window.
(erc-scrolltobottom-mode, erc-scrolltobottom-enable,
erc-scrolltobottom-disable): Use `erc--scrolltobottom-setup' instead
of `erc-add-scroll-to-bottom' for adding and removing local hooks and
instead of ranging over buffers when removing them.  Also add and
remove new hook members when `erc-scrolltobottom-all' is non-nil.

`erc-possibly-scroll-to-bottom' that try to avoid scrolling repeatedly
for no reason.
(erc--scrolltobottom-on-pre-command-relaxed,
erc--scrolltobottom-on-post-command-relaxed): New commands to help
implement `erc-scroll-to-bottom-relaxed'.
(erc--scrolltobottom-at-prompt-minibuffer-active): New function to
scroll to bottom on window configuration changes when using the
minibuffer.
(erc--scrolltobottom-all): New function to scroll all windows
displaying the current buffer.
(erc-add-scroll-to-bottom): Deprecate this function because it is now
unused in the default client and trivial to implement otherwise.
(erc--scrolltobottom-setup): New generic function to perform teardown
as well as setup depending on the state of the module's mode variable.
Also add an implementation specifically for `erc-scrolltobottom-all'
that locally modifies different sets of hooks depending on
`erc-scrolltobottom-relaxed'.
(erc--scrolltobottom-on-pre-insert): New generic function that
remembers the last `window-start' and maybe the current screen line
before inserting a message, in order to restore it afterward.
(erc--scrolltobottom-confirm): New function, a replacement for
`erc-scroll-to-bottom' that returns non-nil when it's actually
recentered the window.  For now, used only when
`erc-scrolltobottom-all' is enabled.
(erc-move-to-prompt-setup): Add `erc-move-to-prompt' to
`pre-command-hook' at a depth of 70 in the current buffer.
(erc-keep-place-mode, erc-keep-place-enable): Change hook depth from 0
to 85.
(erc--keep-place-indicator-setup): Add overlay arrow `after-string' in
non-graphical settings in case users have time stamps or other content
occupying the left margin.
(erc-keep-place-indicator-mode, erc-keep-place-indicator-enable):
Change hook depth from 90 to 85 locally so as not to conflict with a
value of t, for append.
(erc--keep-place-indicator-on-global-module): Change hook depth from
90 to 85 locally.

(erc-echo-timestamp-format): Add additional Custom choice constants
and make the existing default one of them.

`erc-echo-timestamps' and function `erc-echo-timestamp'.
(erc-stamp-mode, erc-stamp-enable, erc-stamp-disable): Call
`erc-stamp--setup' instead of `erc-munge-invisibility-spec'.
(erc-stamp--current-time): Use `current-time' instead of

(erc-add-timestamp): Improve readability slightly, and change
`fboundp' to `functionp' to avoid signaling an error when the
variable's value is not a symbol.
(erc-munge-invisibility-spec): Perform teardown when boolean flag
options, like `erc-timestamp-intangible' and `erc-echo-timestamps' are
nil.

helper state variable to tell Emacs not to clear the current timestamp
message when navigating within the same IRC message.

* lisp/erc/erc.el (erc--parse-user-regexp-legacy,

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-speedbar--shutting-down-p): New flag variable to avoid recursive
calls to `dframe-close-frame' and friends.
(erc-nickbar-mode, erc-nickbar-enable, erc-nickbar-disable): Move
logic formerly performed by `speedbar-disable-update' to
`erc-speedbar--toggle-nicknames-sidebar'.  When disabling, guard
against recursive calls to `dframe-close-frame' and friends.
(erc-speedbar--get-timers): New utility function, also for use in

* 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-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.

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)

2716dd13ce Decouple keep-place-indicator from global ERC module
* etc/ERC-NEWS: Let users know that `keep-place-indicator' is a wholly
separate module from `keep-place'.
* lisp/erc/erc-goodies.el (erc-keep-place-indicator-setup): Perform
some housekeeping on `erc-keep-place-mode'.
(erc-keep-place-indicator-mode, erc-keep-place-indicator-enable,
erc-keep-place-indicator-disable): Take precautions to work around the
activation state of global module `keep-place', but no longer depend
on it.
(erc--keep-place-indicator-on-global-module): New function to ensure
`erc-keep-place' runs exactly once on `erc-insert-pre-hook',
regardless of whether module `keep-place' is active.

(erc-goodies-tests--assert-kp-indicator-on,
erc-goodies-tests--assert-kp-indicator-off,

logic and rename former to latter.
(erc-keep-place-indicator-mode--global): New test.  (Bug#59943)

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.

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-valued
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--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-close-nicknames-window): Add commands to close speedbar
window and toggle its cyclability.
(erc-speedbar--compose-nicks-face): Add helper for nicks integration.

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-bufbar-mode, erc-bufbar-enable, erc-bufbar-disable): New module
named `bufbar' 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.

rendering sidebar.
(erc-status-sidebar-kill):  Disable `erc-bufbar-mode' when active.
(erc-status-sidebar-click): Appeal to option
`erc-status-sidebar-display-action' for `pop-to-buffer' action.

erc-status-sidebar-recenter): Add commands to scroll and
recenter sidebar from a target buffer's window.
(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.  (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)

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-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

d45770e8d0 Optionally combine faces in erc-display-message
* etc/ERC-NEWS: Tell module authors that `erc-display-message' can now
combine faces.
* lisp/erc/erc-button.el (erc-button--display-error-notice-with-keys):
Ask `erc-display-message' to compose `erc-notice-face' and
`erc-error-face'.
* lisp/erc/erc-match.el (erc-hide-fools): Merge `invisible' prop
`erc-match' with existing, if present, and move body to helper for
hiding matched messages.
(erc-match--hide-message): New helper function to hide messages
regardless of match type.
* lisp/erc/erc-track.el: (erc-track-faces-priority-list): Note in doc
string that faces reserved for critical messages are always
prioritized.  Wrap :type declaration in macro helper to ensure
`erc-button' is loaded beforehand.  Otherwise calling `setopt' with
the option's default value fails.
(erc-track--attn-faces): Add new internal variable for faces that
should always appear in the mode line, at least in the default client.
(erc-track-modified-channels, erc-track-face-priority): Prepend
`erc-track--attn-faces' to `erc-track-faces-priority-list'.
* lisp/erc/erc.el (erc-send-action): Ask `erc-display-message' to
apply both `erc-input-face' and `erc-action-face' to messages.
(erc--compose-text-properties): New internal variable to act as flag
for altering behavior of `erc-put-text-property'.
(erc--merge-prop): New function copied from `erc-button-add-face' for
general internal use with any text property by all of ERC.
(erc-display-message-highlight): Set fallback face to
`erc-default-face' the symbol instead of the string.  For this to
break third-party code, callers would have to supply erroneous types
for nonexistent or undefined handlers and then explicitly check for
and depend on such misuse, which seems unlikely and therefore not
worth mentioning in etc/ERC-NEWS.
(erc-display-message): Explain how `type' param works when it's a
list.  Fix code in type-as-list branch so that it optionally combines
faces instead of clobbers them.
(erc-put-text-property): Unalias from `put-text-property', but fall
back to the latter unless caller wants to combine faces, in which case,
defer to `erc--merge-prop'.
* test/lisp/erc/erc-button-tests.el
(erc-button--display-error-notice-with-keys): Expect a combined "error
notice" face.  (Bug#64301)

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

4d6ed774fe Respect existing invisibility props in erc-stamp
* etc/ERC-NEWS: mention `erc-match-toggle-hidden-fools' and new
merging behavior when handling `invisible' text property.
* lisp/erc/erc-match.el (erc-hide-fools): change `invisible' property
to `erc-match' for all messages, not just those with offset bounds.
(erc-match--modify-invisibility-spec): Fix error in doc string.
(erc-match-toggle-hidden-fools): New command.
* lisp/erc/erc-stamp.el (erc-stamp--invisible-property): Add new
internal variable to hold existing `invisible' property merged with
the one registered by this module, the non-namespaced `timestamp'.
(erc-stamp--skip-when-invisible): Add new internal variable, an escape
hatch for pre-ERC-5.6 behavior in which timestamps were not applied at
all to invisible messages.  This led to strange-looking, uneven logs,
and it prevented other modules from offering toggle functionality for
invisibility-spec members registered to them.
(erc-add-timestamp): Merge with existing `invisible' property, when
present, instead of clobbering, but only when escape hatch
`erc-stamp--skip-when-invisible' is nil.
(erc-insert-timestamp-left, erc-format-timestamp): Use possibly merged
`invisible' prop value.  Don't bother with `isearch-open-invisible',
which only affects overlays.
(erc-insert-timestamp-right): Bind `buffer-invisibility-spec' to nil
when figuring `current-column'.  Apply `invisible' text prop to white
space around stamp.
* test/lisp/erc/erc-scenarios-match.el: Require `erc-fill' and
`erc-stamp'.
(erc-scenarios-match--invisible-stamp): Move common setup and core
assertions for some stamp and invisibility-related tests into a
fixture-like helper.
(erc-scenarios-match--stamp-left-fools-invisible): Fix temporarily
disabled test and use fixture.
(erc-scenarios-match--find-eol): New helper.
(erc-scenarios-match--stamp-right-fools-invisible,
erc-scenarios-match--stamp-right-invisible-fill-wrap,
erc-scenarios-match--stamp-both-invisible-fill-static): New tests.

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
function based on those in shell.el.
* test/lisp/erc/erc-dcc-tests.el
(erc-dcc-tests--erc-dcc-do-GET-command): Accept new `nuh' argument
representing message source/sender.
(erc-dcc-do-GET-command): Add tests for regression involving pipe
character.
* test/lisp/erc/erc-tests.el (erc--split-string-shell-cmd): New test.

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)

6ce957154b Redo erc-nickname-in-use-functions as a local module
* etc/ERC-NEWS: Mention new module `services-regain'.
* lisp/erc/erc-backend.el: Rename option.
* lisp/erc/erc-services.el (erc-services-regain-alist): Strategies for
regaining a lost nickname on reconnect.  This option, in addition to
the rest of these changes, is a redo of
`erc-nickname-in-use-functions' from commit 8c0c9826 "Add hook to
regain nickname in ERC", which originally stemmed from bug#62044.
(erc-services-retry-nick-on-connect, erc-services-issue-regain,
erc-services-issue-ghost-and-retry-nick): New function variants for
`erc-services-regain-alist.
(erc-services-regain-mode, erc-services-regain-enable,
erc-services-regain-disable): New local module to activate
nick-regaining behavior.
(erc--nickname-in-use-make-request): New method, a services-specific
implementation.
* lisp/erc/erc.el (erc--nickname-in-use-make-request): New generic
function to request alternate nick when first choice is rejected.
(erc-nickname-in-use): Call `erc--nickname-in-use-make-request' to
request alternate nick.
* test/lisp/erc/erc-scenarios-services-misc.el
(erc-scenarios-services-misc--reconnect-retry-nick): Adopt renamed
version of `erc-scenarios-base-renick-auto-regain'.
(erc-scenarios-services-misc--regain-command,
erc-scenarios-services-misc--ghost-and-retry-nick): New tests.
* test/lisp/erc/resources/services/regain/reconnect-retry-again.eld:
New test data file reusing existing blob c0529052 that once lived at
resources/base/renick/regain/normal-again.eld.
* test/lisp/erc/resources/services/regain/reconnect-retry.eld: New
test data file reusing existing blob 9f4df70e5 that once lived at
resources/base/renick/regain/normal.eld.
* test/lisp/erc/resources/services/regain/taken-ghost.eld: New test
data file.

99d74dcd45 Account for leading timestamps in erc-match
* lisp/erc/erc-match.el (erc-text-matched-hook): Mention that stamps
may be present in the narrowed buffer but absent from the message
parameter.
(erc-match--message): New function containing what was the body of
`erc-match-message' as if the latter were simply renamed.
(erc-match-message): Move body to `erc-match--message' and call it
with more aggressive narrowing.  This fixes a regression stemming from
d880a08f "Cement ordering of essential hook members in ERC".  Special
thanks to Libera.Chat user jrm for reporting this bug.  (Bug#60936)
* test/lisp/erc/erc-scenarios-match.el: New test file.

longer exists.

56e1922281 Revert "Add hook to regain nickname in ERC"
This reverts commit 8c0c982684.  The
functionality it introduced is likely being migrated to a
"regain"-specific local module to live in the library erc-services.el
alongside the existing `services' module.  Its scope will be expanded
to address common "regain" cases requiring NickServ.  This commit is
being reverted to prevent any confusion that might arise from users
encountering the old interface while the new one is being hashed out
on the tracker.

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-dcc-tests--erc-dcc-do-GET-command): Use helper to initialize
prompt and markers.
* test/lisp/erc/erc-networks-tests.el

erc-networks--rename-server-buffer--existing--reuse,
erc-networks--rename-server-buffer--existing--noreuse,

erc-networks--rename-server-buffer--existing--live,

initialize prompt and bounding markers.
* test/lisp/erc/erc-stamp-tests.el (erc-stamp-tests--insert-right):
Use `erc--initialize-markers' for setting up prompt.
* test/lisp/erc/erc-tests.el (erc--refresh-prompt): Adjust assertions

hook depth for `erc-button-add-buttons' from 90 to 30.
* lisp/erc/erc-fill.el (erc-fill-mode, erc-fill-enable): Change hook
depth for `erc-fill' from 0 to 40.

hook depth for `erc-match-message' from 90 to 60.

hook depth for `erc-add-timestamp' from 90 to 50.
* test/lisp/erc/erc-tests.el
(erc-tests--assert-printed-in-subprocess): Add fixture for testing a
form printed from a subprocess.
(erc--find-mode, erc--essential-hook-ordering): Use helper in existing
