* etc/ERC-NEWS: Add entry explaining removal of automatic `intangible'
propertizing of t-valued `invisible' messages.
* lisp/erc/erc.el (erc--insert-invisible-as-intangible-p): New flag
variable, a temporary escape hatch to regain pre-5.6 behavior
involving the modification of certain `invisible' messages.
(erc--insert-line): Gate unfavorable behavior behind
`erc--insert-invisible-as-intangible-p' flag. Add comment clarifying
deferred initialization of `insert-position', which was part of the
many changes introduced as part of bug#60936.
* lisp/erc/erc-fill.el (erc-fill--wrap-rejigger-region): Call
`erc--get-inserted-msg-end' instead of `erc--get-inserted-msg-bounds'
with `end' arg.
* lisp/erc/erc-truncate.el (erc-truncate-buffer-to-size): Call
`erc--get-inserted-msg-beg' with `point' instead of
`erc--get-inserted-msg-bounds' with `beg' arg.
* lisp/erc/erc.el (erc--get-inserted-msg-beg-at,
erc--get-inserted-msg-end-at): New macros.
(erc--get-inserted-msg-beg, erc--get-inserted-msg-end): New functions.
(erc--get-inserted-msg-bounds): Convert to function with different
signature, and refactor. This was introduced for the yet unreleased
5.6 (Emacs 30) by bug#60936.
(erc--get-inserted-msg-prop): Use `erc--get-inserted-msg-beg' instead
of `erc--get-inserted-msg-bounds' with `beg' arg.
(erc--delete-inserted-message): Update call site of
`erc--get-inserted-msg-bounds' to match new signature.
(erc-cmd-CLEAR): Use `erc--get-inserted-msg-beg' instead of
`erc--get-inserted-msg-bounds' with `beg' arg.
* test/lisp/erc/erc-scenarios-match.el
(erc-scenarios-match--stamp-right-fools-invisible): Call
`erc--get-inserted-msg-end' instead of `erc--get-inserted-msg-bounds'.
* test/lisp/erc/erc-tests.el (erc-tests--get-inserted-msg-setup,
erc-tests--assert-get-inserted-msg,
erc-tests--assert-get-inserted-msg/basic,
erc-tests--assert-get-inserted-msg/stamp,
erc-tests--assert-get-inserted-msg-readonly-with): New helper
functions.
(erc--get-inserted-msg-beg/basic, erc--get-inserted-msg-beg/readonly,
erc--get-inserted-msg-beg/stamp,
erc--get-inserted-msg-beg/readonly/stamp,
erc--get-inserted-msg-end/basic, erc--get-inserted-msg-end/stamp,

erc--get-inserted-msg-end/readonly/stamp,
erc--get-inserted-msg-bounds/readonly,
erc--get-inserted-msg-bounds/stamp,
erc--get-inserted-msg-bounds/readonly/stamp): New tests.
(erc--get-inserted-msg-bounds, erc--get-inserted-msg-bounds/basic):
Move `beg' and `end' cases to separate test variants and rename former
to latter.
* doc/misc/erc.texi (auth-source): Add new "Troubleshooting"
subsection.
* lisp/erc/erc.el (erc-open): Initialize markers before determining
session parameters. Otherwise, functions that rely on
`erc-inset-marker' being non-nil, like `erc-check-text-conversion',
may fail during auth-source lookups.
(erc-auth-source-search): When non-interactive, ask the user whether
to continue connecting anyway. (Bug#67978)
* lisp/erc/erc-button.el (erc-button--display-error-notice-with-keys):
Currently, internal "error notices" do not have timestamps. However,
this causes alignment issues for non-`fill-wrap' users of left-sided
stamps. The heuristic used by this change for detecting such stamps
is weak and prone to false negatives.
* lisp/erc/erc-log.el (erc-log-mode, erc-log-enable): Set explicit
depth for `erc--pre-clear-functions' to 50.
(erc-save-buffer-in-logs): Fix partial regression in which redundant
text would appear in logs that have undergone truncation via an
interactive call to this command when the deprecated option
`erc-truncate-on-save' is non-nil.
* lisp/erc/erc-stamp.el (erc-stamp-mode, erc-stamp-enable): Set
depth for `erc--pre-clear-functions' to 40.
(erc-stamp--reset-on-clear): Only add `erc-stamp--insert-date-hook'
when `erc-stamp--date-mode' is active.
* lisp/erc/erc.el (erc-cmd-CLEAR): Rework to honor but improve upon
the old behavior when called from lisp. Do this by attempting to find
the beginning of the current message and excluding it from the
truncated portion of the buffer. A NEWS entry describing this
behavior already exists for 5.6.
* test/lisp/erc/erc-scenarios-log.el
(erc-scenarios-log--save-buffer-in-logs/truncate-on-save): New test.
These changes originate from bug#60936.
* lisp/erc/erc-button.el
(erc-button--display-error-notice-with-keys-and-warn): Use
`erc--lwarn' so the warnings buffer is overridable for testing.
* lisp/erc/erc-sasl.el (erc-sasl-mode, erc-sasl-enable): Signal an
`error' instead of calling `erc-error', which continues execution. In
this special case, the session cannot continue initializing, since
connection registration can't reasonably be expected to complete
successfully.
(erc-sasl--destroy): Don't run `erc-quit-hook', and issue a warning of
level `:error' to get users' attention instead of calling `ding'.
* lisp/erc/erc-speedbar.el
(erc-speedbar--emulate-sidebar-set-window-preserve-size): Don't set
window parameters. Doing this basically made
`erc-speedbar-toggle-nicknames-window-lock' unusable.
(erc-speedbar--toggle-nicknames-sidebar): Manually unlock the window
after toggling.
(erc-nickbar-mode, erc-nickbar-enable, erc-nickbar-disable): Don't
`ding' when called in a non-ERC buffer, and make sure to call
`erc-speedbar--ensure' from an ERC buffer. Also, don't disable
minor-mode var when speedbar buffer doesn't exist because that doesn't
ensure it'll be created the next time around, and users may count on
the activation state remaining consistent.
(erc-speedbar-toggle-nicknames-window-lock): Make usable from lisp
with explicit numeric arg.
* lisp/erc/erc-status-sidebar.el (erc-bufbar-mode, erc-bufbar-enable):
Only create the side window from an erc-mode buffer to ensure the
ratio is preserved when burying the current buffer, e.g., with
`custom-buffer-done'.
* lisp/erc/erc.el (erc--warnings-buffer-name, erc--lwarn): New
function, an analog of `lwarn', that allows for overriding the
warnings buffer with the new variable `erc--warnings-buffer-name'.
(erc-cmd-SERVER): Add comment.
* test/lisp/erc/erc-scenarios-sasl.el
(erc-scenarios-sasl--plain-fail): Expect warning instead of error.
* test/lisp/erc/erc-scenarios-status-sidebar.el
(erc-scenarios-status-sidebar--bufbar): Refresh when interactive as
well.
* test/lisp/erc/resources/sasl/plain-failed.eld: Expect EOF instead of
"CAP END". (Bug#63595)
* lisp/erc/erc-backend.el (erc-server-PRIVMSG): Don't set string
intended for insertion to the undefined return value of
`erc-process-ctcp-reply' and `erc-process-ctcp-query'. Rework control
flow slightly for clarity.
* lisp/erc/erc.el (erc-process-ctcp-reply): Bind
`erc--msg-prop-overrides' and populate with `erc--ctcp' and `erc--cmd'
"msg props" for the benefit of `erc-display-message' calls made by
the various CTCP reply handlers. (Bug#67677)
* lisp/erc/erc-networks.el: Lose some unneeded forward declarations.
* lisp/erc/erc.el (erc-open-socks-tls-stream): Don't conflate SOCKS
with TOR by mentioning a ".onion" address for the `host' parameter.
* test/lisp/erc/erc-tests.el
(erc--check-prompt-input-for-multiline-blanks): Extend timeout.
* lisp/erc/erc-button.el (erc-button--nick): Add `face-cache' slot.
(erc-button-add-nickname-buttons): Pass `erc-button--nick' object, if
created', as the boolean NICK-P parameter when calling
`erc-button-add-button'. Keeping the latter function ignorant of
`erc-button--nick' is of course preferable, but some coordination is
now required to convey and use the "face cache". We can introduce an
abstraction, like a local variable, if this becomes an issue.
(erc-button-add-button): Use `erc--merge-prop' instead of
`erc-button-add-face' to apply button faces. Hold off on deprecating
the latter because it provides unique functionality for nesting faces.
Also, consult NICK-P if it's an `erc-button--nick' object for the
various overriding faces it knows about.
* lisp/erc/erc-nicks.el (erc-nicks-track-faces): New option.
(erc-nicks--get-face): Make generated face `:inherit' from
`erc-nicks-backing-face'.
(erc-nicks--highlight): Just return the generated face instead of
combining it with `erc-nicks-backing-face'.
(erc-nicks--highlight-button): Set the `face-cache' slot of the
`erc-button--nick' object when `track' is loaded and initialized.
(erc-nicks-mode, erc-nicks-enable, erc-nicks-disable): Add and remove
`track' integration.
(erc-nicks--reject-uninterned-faces): New function to remove faces
created by `nicks' from buttonized speakers and mentions. Conform
to `erc-track--face-reject-function' interface.
(erc-nicks--ourps, erc-nicks--check-normals): New function and helper
for `erc-track--alt-normals-function' interface.
(erc-nicks--setup-track-integration): New function.
(erc-nicks--remember-face-for-track): New function to cache
nick faces owned by this module.
* lisp/erc/erc.el (erc--merge-prop): Add new optional parameter
`cache-fn', and when non-nil, call it, assigning the returned value to
that of the merged property.
* test/lisp/erc/erc-nicks-tests.el (erc-nicks-list-faces): Skip
the "Inherit: " button. (Bug#67767)
* etc/ERC-NEWS: Mention name change.
* lisp/erc/erc-backend.el (erc-process-sentinel): Don't create an
empty `erc-channel-users' hash table in server buffers. This is
arguably a bug fix as well as a minor breaking change.
* lisp/erc/erc-common.el (erc-get-channel-user,
erc-get-channel-member): Rename and alias former to latter.
* lisp/erc/erc.el (erc-channel-users, erc-channel-members): Rename
former to latter. The old name invited much confusion because the
table's values are not mere `erc-channel-user' instances but cons
cells that include them and their corresponding server users.
* etc/ERC-NEWS: Mention change even though the API remains
undisturbed.
* lisp/erc/erc-common.el (erc-channel-user): "Encode" status prefix
slots `voice', `halfop', `op', `admin', and `owner' as single `status'
slot. Add backward-compatible constructor. Although the old layout
was overly sparse, since the vast majority of users have no membership
status at all, the point here is not to trade time for space but
rather to improve human readability of ERC buffer substrings
containing text props that reference `erc-channel-user' objects.
* lisp/erc/erc.el (erc--define-channel-user-status-compat-getter):
Helper macro for declaring compat-oriented "getters" for status-prefix
slots of `erc-channel-user'.
(erc-channel-user-voice, erc-channel-user-halfop, erc-channel-user-op,
erc-channel-user-admin, erc-channel-user-owner): Add compat getters.
These are not new functions. They were previously defined by the
`erc-channel-user' `cl-defstruct' in erc-common.el.
(erc--update-cusr-status-if-changed): New helper macro to make
`erc-update-current-channel-member' more readable.
(erc-update-current-channel-member): Collapse some overly verbose
"unrolled" forms using helper macro and more compact expressions.
* test/lisp/erc/erc-tests.el (erc-channel-user): New test.
* doc/misc/erc.texi: Replace option `erc-format-nick-function' with
`erc-show-speaker-membership-status'.
* etc/ERC-NEWS: Mention shift to template-based speaker formatting.
Also mention in-buffer STATUSMSG support and various name changes and
new formatting-related options.
* lisp/erc/erc-backend.el (erc-format-privmessage): Remove forward
declaration.
(erc--determine-speaker-message-format-args): Add forward declaration.
(erc--statusmsg-target): New utility function for detecting whether
the current target is status-prefixed.
(erc-current-message-catalog): Move here from lisp/erc/erc.el.
(erc--message-speaker-catalog): New variable.
(erc--speaker-status-prefix-wanted-p): New variable specifically for
the function `erc-format-@nick' to signal it wants status-prefixes
prepended to the displayed nick.
(erc-server-PRIVMSG): Initialize `let'-bound value of
`erc--msg-prop-overrides' to a dummy `erc--tmp' property with a null
value that `erc-display-message' will "strip" before calling its
hooks. Move away from the rather blunt symbol `msg' as a useful value
for `erc--msg'. Instead, allow `erc-display-message' to assign the
most appropriate value based on context. Also, bind the variable
`erc-current-message-catalog' to whatever the buffer's
`erc--message-speaker-catalog' happens to be. Future internal modules
can set this to alternative catalogs as needed. Additionally, detect
STATUSMSG prefixes on targets and inform the formatting logic of the
verdict. Lastly, and most importantly, use the function
`erc--determine-speaker-message-format-args' instead of
`erc-format-privmessage' for message formatting. Pass along the
returned "catalog key" and spec parameters to `erc-display-message'.
However, for NOTICEs, continue to render the string, as before, for
the two "echo notice" hooks.
* lisp/erc/erc-common.el (erc--ctcp-response): New "subsclass" of
`erc-response' for smuggling extra information to CTCP query handlers
in a mostly backwards-compatible way. The same approach could be
taken with the "echo notice" hooks mentioned above.
* lisp/erc/erc-dcc.el (erc-dcc-chat-filter): Add `erc--spkr' and
`erc--speaker' properties even though these chat buffers are not
`erc-mode' buffers.
* lisp/erc/erc-fill.el (erc-fill--wrap-last-msg,
erc-fill--wrap-max-lull): Add doc strings.
(erc-fill--wrap-continued-message-p): Rework to look for `erc--spkr'-
`erc--msg' combinations as indicators of speaker continuity.
(erc-fill--wrap-rejigger-region): Remove reference to the no longer
relevant `erc-stamp-type'. Instead, use the `erc--msg' property
combined with the `erc-timestamp' field to detect date stamps because
all are currently left-sided.
* lisp/erc/erc-stamp.el (erc-stamp--propertize-left-date-stamp): Don't
add superfluous `erc-stamp-type' property.
* lisp/erc/erc.el (erc--msg-props): Revise purpose and meaning of
`erc--msg' by removing possible value `msg', which was previously
meant to indicate that a message had a "speaker". Instead, rely on
the separate `erc--spkr' property to convey this information, with
`erc--msg' now expressing a "type" or "role".
(erc--use-language-catalog-for-ctcp-action-p): New variable, a
compatibility switch to help transition from the `ACTION' entry of the
language catalog to the `ctcp-action' family of entries in the new
`-speaker' catalog.
(erc--ensure-spkr-prop): Update to include any passed-in environmental
overrides.
(erc--send-action-display): Restore pre-5.6 behavior when
compatibility flag enabled. Otherwise, use new `-speaker' catalog for
formatting inserted message.
(erc--send-message-external): Overhaul to behave more faithfully in
mimicking a line submitted at the prompt of the current target buffer.
(erc--own-property-names): Remove `erc-stamp-type'.
(erc-ensure-target-buffer-on-privmsg): Add new choice variant for old
default behavior and change meaning of default to mean "except for
STATUSMSGs". This option is newly revived for ERC 5.6.
(erc--message-speaker-statusmsg, erc--message-speaker-statusmsg-input,
erc--message-speaker-input, erc--message-speaker-input-chan-privmsg,
erc--message-speaker-input-chan-notice,

erc--message-speaker-ctcp-action,
erc--message-speaker-ctcp-action-input,
erc--message-speaker-ctcp-action-statusmsg,
erc--message-speaker-ctcp-action-statusmsg-input): New variables for
new `speaker' format-template catalog.
(erc--speakerize-nick): New helper function.
(erc--determine-speaker-message-format-args): New function to find the
appropriate format key from various contextual parameters. Could
become the default of a function-valued variable for internal use.
(erc-show-speaker-membership-status): New option.
(erc-format-nick-function, erc-speaker-from-channel-member-function):
Declare former as an obsolete alias for the latter, and redefine
purpose slightly.
(erc-format-nick-function, erc-determine-speaker-from-user): Rename
former to latter and obsolete the old name.
(erc-format-nick, erc-determine-speaker-from-user): Rename former to
latter and obsolete old name.
(erc-format-@nick): Deprecate and adapt for use with new
template-based formatting paradigm.
(erc-format-my-nick): Move `erc-speaker' text prop toward head of
list, meaning it will end up beneath `font-lock-face' in the final
output.
(erc--format-speaker-input-message): New function to replace
`erc-format-my-nick' in-tree.
(erc-process-ctcp-query): Don't bind `erc--msg' to `msg'. Instead,
rely on `erc-display-message' to set it to the current template key.
(erc-ctcp-query-ACTION): Prefer using formatting template, but attempt
to simulate pre-5.6 behavior when compatibility flag enabled.
(erc-display-msg): Use `erc--format-speaker-input-message' instead of
`erc-format-my-nick'. Ignore `erc--msg-prop-overrides' with null
values.
(erc-current-message-catalog): Move to erc-backend.el.
* test/lisp/erc/erc-scenarios-base-statusmsg.el: New file.
* test/lisp/erc/erc-scenarios-stamp.el
(erc-scenarios-stamp--left/display-margin-mode): Expect format catalog
key instead of unhelpful `msg' as value of `erc--msg' prop.
* test/lisp/erc/erc-tests.el (erc-message): Render format template in
mock function and expect string in assertions.
(erc-tests--format-privmessage): New function, a helper for the
following test.
(erc-format-privmessage, erc--determine-speaker-message-format-args):
Rename former to latter and suppress deprecation warning.
(erc--determine-speaker-message-format-args/queries,
erc--determine-speaker-message-format-args/queries-as-channel): New
tests.
(erc-tests--format-my-nick): New helper function for the following
test.
(erc--format-speaker-input-message): New test.
* test/lisp/erc/resources/base/display-message/statusmsg.eld: New
file. (Bug#67677)
; * test/lisp/erc/resources/fill/snapshots/merge-wrap-01.eld: Update.
; * test/lisp/erc/resources/fill/snapshots/merge-wrap-indicator-post-01.eld:
; Update.
; * test/lisp/erc/resources/fill/snapshots/merge-wrap-indicator-pre-01.eld:
; Update.
* etc/ERC-NEWS: Mention combined face ordering for "/me" messages.
* lisp/erc/erc-backend.el (erc-server-PRIVMSG): Bind
`erc--msg-prop-overrides' for the extent of this function's execution,
which means a large amount of code will see this variable as being
non-nil. However, no calls to `erc-display-message' or
`erc-display-msg' should occur other than the one handling the final
insertion. Code needing to influence the current message's "msg
props" can push new pairs onto this value, which will override any
existing collisions.
* lisp/erc/erc-fill.el (erc-fill): Switch to `erc--spkr' as sentinel
property.
(erc-fill--wrap-continued-message-p): Look for `erc--spkr' property
instead of `erc-speaker'.
* lisp/erc/erc.el (erc--msg-props): Mention `erc--spkr' in doc.
(erc--send-action-perform-ctcp): Add `erc--spkr' property. Fix bug in
which `erc-my-nick-face' appeared below `erc-input-face' in the
speaker portion.
(erc--ensure-spkr-prop): New helper function to propagate speaker
metadata.
(erc--ranked-properties): Add `erc--spkr', `erc--ctcp', and
`erc--ephemeral'.
(erc-display-message): Use default hash table size when initializing.
Remove unnecessary assignment of `msg' to `erc--msg' for PRIVMSG and
NOTICE commands. Bind `string' below `erc--msg-props' so that
implementers of the function form of the `erc-format-message'
templating interface can read and write the current context's "msg
props".
(erc--own-property-names): Add all `erc--msg-props' props by
subsumation.
(erc--get-speaker-bounds): Use `erc--spkr' instead of `erc--msg' as a
sentinel to detect a chat message guaranteed to have an `erc--speaker'
text-property interval.
(erc-format-privmessage, erc-format-my-nick, erc-ctcp-query-ACTION):
Add `erc--spkr' to `erc--msg-prop-overrides' when available.
* test/lisp/erc/erc-fill-tests.el: (erc-fill-tests--insert-privmsg):
Bind `erc--msg-prop-overrides'.
(erc-fill-tests--compare): Require environment variable value to match
current test name exactly when saving snapshots. Add `erc--msg-props'
individually to white list.
* test/lisp/erc/erc-tests.el (erc--order-text-properties-from-hash):
Include `erc--spkr'. (Bug#60936) (Bug#67677)

; * test/lisp/erc/resources/fill/snapshots/stamps-left-01.eld: Update.
* lisp/erc/erc-backend.el (erc-server-PRIVMSG): Don't bother running
`erc-ignored-user-p' and `erc-ignored-reply-p' when their associated
options are null. The option `erc-ignore-list' is buffer-local when
set, and `erc-ignored-user-p' looks for it in the server buffer.
Moreover, all functions that set it, like `erc-cmd-IGNORE' and
`erc-cmd-UNIGNORE', do so in the server buffer. And the response
handler in question only runs in server buffers, so this shouldn't
break anything. Also, remove stray call to reassign trailing response
contents.
* lisp/erc/erc-common.el (erc-get-server-user): Rearrange so
`erc-with-server-buffer' doesn't have to switch to the server buffer
because `erc-downcase' can run in channels as well.
* lisp/erc/erc.el (erc-ignored-user-p): Add comment. (Bug#67677)
* etc/ERC-NEWS: Mention renaming of `erc-get-user-mode-prefix'.
* lisp/erc/erc-speedbar.el (erc-speedbar-insert-user): Use
`erc-get-channel-membership-prefix' so that nicks in the nickbar can
have prefixes beyond just those for "voice" and "op".
* lisp/erc/erc.el (erc-get-user-mode-prefix,
erc-get-channel-membership-prefix): Rename former to latter because
"user mode" suggests the function somehow involves user modes, but it
exclusively concerns channel modes. Also, overload the only parameter
in order to avoid redundantly looking up `erc-channel-user' object
with every predicate call. In the near future, ERC will likely need
to offer an alternate version of this function that returns multiple
prefixes instead of just one.
(erc-format-@nick): Actually use the `channel-data' parameter.
(erc-format-my-nick, erc--format-channel-status-prefix): Use new name
for function `erc-get-user-mode-prefix'. (Bug#63595) (Bug#67677)
* lisp/erc/erc.el (erc--check-prompt-input-for-running-process):
Resolve dissonance between content of ancient `user-error' message and
condition that triggered it by favoring the former because it's
supported by the underlying mechanism, which revolves around the
`process-not-needed' symbol property.
* test/lisp/erc/erc-tests.el (erc--check-prompt-input-functions):
Revise expected output for error assertion. (Bug#66073, originally
from bug#54536, and included for discussion in bug#67677)
* lisp/erc/erc-backend.el (erc-server-396, erc-server-396-functions):
Define response handler for 396 numeric. For now, always display the
message in the active buffer rather than bother with something like
`erc-once-with-server-event' to try and suss out when this is a
response to something client-initiated, like a /VHOST. Do this
despite most users probably wanting the message to appear in the
server buffer alone when the response is server-initiated. The
`labeled-response' extension will hopefully make dealing with such
matters less of a crapshoot.
* lisp/erc/erc.el (erc--parse-user-regexp-pedantic): Tweak slightly to
allow null groups and favor host.
(erc--parse-user-regexp-legacy, erc--parse-user-regexp): Remove the
first variable but preserve its value as that of the second.
(erc--parse-nuh): New function. The behavior is nuanced and complex
and so not easily described in a doc string.
(erc-message-english-396): Define format template for 396 response.
* test/lisp/erc/erc-scenarios-misc-commands.el
(erc-scenarios-misc-commands--VHOST): New test.
* test/lisp/erc/erc-tests.el (erc-parse-user): Move "pedantic" section
to new test.
(erc--parse-nuh): New test.
* test/lisp/erc/resources/commands/vhost.eld: New test data file.
(Bug#67677)
* etc/ERC-NEWS: Fix entry regarding `erc-input-refoldp'.
* lisp/erc/erc-common.el (erc-input): Remove `refoldp' slot, which was
to be new in 5.6, in order to reduce churn in the extremely unlikely
event that third-party code uses the read-syntax of these objects or
ones subclassed from it for some other purpose, outside of
`erc-pre-send-functions'.
(erc--input-split) Add `refoldp' slot here instead.
* lisp/erc/erc.el (erc-pre-send-functions): Amend doc string to stress
that `refoldp' is not a real slot.
(erc--input-ensure-hook-context, erc-input-refoldp): New function, an
impostor accessor for the nonexistent `refoldp' slot of `erc-input',
and a helper function for asserting a valid context at runtime.
(erc--run-send-hooks): Don't copy over `refoldp' from the
`erc--input-lines' object to the working `erc-insert' object. Check
the insertion context's `erc--input-split' object instead of the
hook's `erc-insert' object when deciding whether to resplit.
* test/lisp/erc/erc-tests.el: Adjust test environment to satisfy
assertion. (Bug#62947)
* lisp/erc/erc-common.el (erc--doarray): Add macro for mapping over
arrays. ERC has the uncommon requirement of having to repeatedly
traverse strings that contain flags for advertised server features.
It doesn't make sense to translate these meanings into enums or
dynamically generate variables for each flag. Hash tables and lists
require additional setup and aren't as compact to inspect.
* lisp/erc/erc-dcc.el (erc-dcc-handle-ctcp-send): Use `string-search'
instead of `seq-contains-p' even though performance doesn't matter
here.
* lisp/erc/erc.el (erc--channel-mode-types): Use `erc--doarray'
instead of `dolist'.
(erc--process-channel-modes): Use `erc--doarray' instead of `dolist',
and don't create a string from current char until needed.
(erc--parse-user-modes): Use `erc--doarray' instead of `dolist'.
* test/lisp/erc/erc-tests.el (erc--doarray): New test. (Bug#67677)
* lisp/erc/erc-backend.el (erc-log-p): Remove declaration entirely.
(erc-server-reconnect): Move declaration for `erc-reuse-buffers' here.
(erc-process-sentinel-1): Move `erc-kill-server-buffer-on-quit'
declaration here.
(erc--conceal-prompt): Move `erc-prompt-hidden' declaration here.
(erc-server-INVITE): Move `erc-invitation' declaration here.
(erc-server-PART): Move `erc-kill-buffer-on-part' declaration here.
(erc-server-PRIVMSG): Move declarations for `erc-minibuffer-ignored',
`erc-receive-query-display', `erc-receive-query-display-defer',
`erc--cmem-from-nick-function', `erc-format-nick-function', and
`erc-format-query-as-channel-p' here.
(erc-server-401): Move `erc-whowas-on-nosuchnick' declaration here.
(erc-server-475): Move `erc--called-as-input-p' and
`erc-prompt-for-channel-key' declarations here.
* lisp/erc/erc-common.el (erc-log-p): Remove declaration for
`erc-log-p' and replace with actual definition.
(erc-log-aux): Move `erc-dbuf' declaration from top level into
function body.
* lisp/erc/erc-fill.el (erc-fill--wrap-continued-message-p): Note in
the doc string that this function produces side effects.
* lisp/erc/erc-networks.el (erc-determine-network,
erc-networks--copy-server-buffer-functions): Move some variable
declarations to function body.
(erc-settings, erc-get): Deprecate for now and explain why in doc
strings. We could deprecate them unconditionally, but they never
provided usable code, and their names are short and valuable.
* lisp/erc/erc.el (tabbar--local-hlf, motif-version-string,
gtk-version-string): Prefer moving these single-serving declarations
to function bodies, if only to make closures from this library less
cluttered when debugging. This should also help avoid stray
declarations.
(erc-hooks, erc-timer-hook): Revise doc strings.
(erc-log-p): Move definition to erc-common.el.
(erc-cmd-SV): Mimic `emacs-version' and stick with `featurep', here in
combination with special-variable declarations, instead of `boundp' or
similar.
(erc-header-line-uses-tabbar-p): Explain that this has nothing to do
with `tab-bar'.
(erc-update-mode-line-buffer): Only assign when bound. This has been
verified to work with version 2.0 on EmacsWiki.
* test/lisp/erc/erc-scenarios-base-reconnect.el: Timeouts.
* test/lisp/erc/erc-scenarios-base-renick.el: Timeouts.
* test/lisp/erc/resources/join/network-id/foonet-again.eld: Timeouts.
* etc/ERC-NEWS: Mention convenience macro being preferred means of
defining message templates. Mention renaming of `notify' formatting
templates.
* lisp/erc/erc-common.el (erc--define-catalog,
erc-define-message-format-catalog): New macro and internal variant to
replace `erc-define-catalog-entry'. The internal variant allows us to
defer reindenting existing definitions until meaningfully edited.

(erc-message-english-netsplit, erc-message-english-netjoin,
erc-message-english-netjoin-done, erc-message-english-netsplit-none,
erc-message-english-netsplit-wholeft): Define at top level using
`defvar'.
* lisp/erc/erc-notify.el (erc-notify-install-message-catalogs):
Deprecate, and rename all format templates with hyphens instead of
underscores.
(erc-notify-timer, erc-notify-JOIN, erc-notify-NICK, erc-notify-QUIT):
Use hyphenated template names.
(erc-cmd-NOTIFY): Use hyphenated template names. Load the module when
necessary and emit a warning. Otherwise, people who discover this
autoloaded command without being aware of the module's existence may
think it's "broken".
(pcomplete/erc-mode/NOTIFY): Replace top-level autoload with `require'
in function body. Include `erc-notify-list' in list of completions,
which makes removal easier if you don't share any channels with a
person, and they're not in `erc-server-users'. A better long-term
solution might be to WHOIS folks we're unsure about when they're
listed in a 303.
(erc-message-english-notify_current, erc-message-english-notify_list,
erc-message-english-notify_on, erc-message-english-notify_off): Define
at top level using `defvar'. Replace nonstandard underscores with
hyphens. Alias obsolete names.

level using `defvar'.
* lisp/erc/erc-sasl.el (erc-message-english-s902,

* lisp/erc/erc-sound.el (erc-message-english-CTCP-SOUND): Define using
`defvar'.
* lisp/erc/erc.el (erc--make-message-variable-name): New function to
replace `erc-make-message-variable-name' internally, where most uses
previously checked whether the returned variable was bound. This
helper now does that conditionally, when asked.
(erc-make-message-variable-name): Defer to internal variant,
`erc--make-message-variable-name'.
(erc-define-catalog-entry, erc-define-catalog): Deprecate.
(erc-retrieve-catalog-entry): Refactor to favor
`default-toplevel-value' of `erc-current-message-catalog' before
falling back to `english'. Not doing this was arguably a bug.

erc-tests-pp-propertized-parts, erc--make-message-variable-name,
erc-retrieve-catalog-entry): New tests along with utility functions
and a convenience command for manipulating catalogs. (Bug#67677)
* lisp/erc/erc.el (erc--initialize-markers): Commit 0d6c8d41ab "Use
overlay instead of text prop to hide ERC's prompt" introduced a bug
that caused the prompt to remain hidden upon reconnecting because the
stashed overlay would get clobbered by ERC's major-mode setup.
Binding its old value while unhiding fixes the issue.
* test/lisp/erc/erc-tests.el (erc-hide-prompt): Don't permanently set
the default value of `erc-hide-prompt'.
* test/lisp/erc/resources/erc-scenarios-common.el
(erc-scenarios-common--join-network-id): Add assertions for prompt
hiding and unhiding on reconnect. (Bug#51082)
* etc/ERC-NEWS: Add entry for `erc-prompt-format'.
* lisp/erc/erc-compat.el (erc-compat--defer-format-spec-in-buffer):
New macro to wrap `format-spec' specification values in functions that
run in the current buffer and fall back to the empty string.
* lisp/erc/erc.el (erc-prompt): Add predefined Custom choice for
function type in `erc-prompt-format'.
(erc--prompt-format-face-example): New "pre-propertized" value for
option `erc-prompt-format'.
(erc-prompt-format): New companion option for `erc-prompt' choice
`erc-prompt-format'. New function of the same name to perform format
substitutions and serve as a Custom choice value for `erc-prompt'.
Based on work and ideas originally proposed by Stefan Kangas.
(erc--away-indicator, erc-away-status-indicator,
erc--format-away-indicator): New formatting function and helper
variables for displaying short away status.
(erc--user-modes-indicator): New variable.
(erc--format-user-modes): New function.
(erc--format-channel-status-prefix): New function.
(erc--format-modes): New function.
* test/lisp/erc/erc-scenarios-prompt-format.el: New file. (Bug#51082)
Co-authored-by: Stefan Kangas <stefankangas@gmail.com>
* lisp/erc/erc.el (erc--merge-prop-behind-p): New variable to be
dynamically bound around rare calls to `erc--merge-props' when the
latter should append to the end of existing list-valued text
properties.
(erc--inhibit-prompt-display-property-p): New variable to be non-nil
in buffers where an active module needs to reserve all uses of the
`display' text property in the prompt region for itself.
(erc--prompt-properties): Collect all common prompt properties in one
place for code reuse and maintenance purposes.
(erc--refresh-prompt-continue, erc--refresh-prompt-continue-request):
New function and state variable for custom `erc-prompt' functions to
indicate to ERC that they need the prompt to be refreshed in all
buffers and not just the current one.
(erc--refresh-prompt): Merge `erc-prompt-face' behind any applied by a
customized `erc-prompt' function value. Crucially, don't inherit
properties at the beginning of the prompt because doing so may clobber
any added by a custom `erc-prompt' function. Instead, apply known
properties from `erc-display-prompt' manually. Integrate
`erc--refresh-prompt-continue' logic.
(erc--merge-prop): Recognize flag to activate `append' behavior in
which new prop values are appended to the tail of existing ones rather
than consed in front. This functionality could be extended to
arbitrary splices as well.
(erc-display-prompt): Use common text properties defined elsewhere.
* test/lisp/erc/erc-tests.el (erc--merge-prop): Add assertion for
`erc--merge-prop-behind-p' non-nil behavior. (Bug#51082)
* etc/ERC-NEWS: Add entry for more expansive "%m" in header line.
* lisp/erc/erc-common.el (erc--channel-mode-types): New slot
`shortargs' for caching truncated mode args.
* lisp/erc/erc.el (erc--mode-line-chanmodes-arg-len): New internal
variable for adjusting the truncation length of channel-mode arguments
as they appear in the header line.
(erc--mode-line-mode-string): New variable for caching the relevant
"modestring", if any, in ERC buffers.
(erc--process-channel-modes): Don't associate args with group 4/D,
which are all nullary modes. This fixes a bug in which arguments were
associated with the wrong letters. Also, set cached mode string for
channel.
(erc--user-modes): Simplify slightly by removing likely useless
variant for overloaded arg AS-TYPE. This function is new in ERC 5.6.
(erc--channel-modes): New function. A higher-level getter for
current channel mode representation to complement `erc--user-modes'.
(erc--parse-user-modes): Set `erc--mode-line-mode-string in server
buffers.
(erc--handle-channel-mode): Change model to associate modes of type A
with a running plus/minus tally of state changes since joining the
channel.
(erc-update-mode-line-buffer): Use cached verbose representation of
channel or user modes instead of calling `erc-format-channel-modes'.
* test/lisp/erc/erc-tests.el (erc--update-channel-modes): Update to
reflect new running tally associations for type A modes.
(erc--channel-modes): New test.
(erc--user-modes): Update to reflect parameter simplification.
(Bug#67220)
* etc/ERC-NEWS: Mention shift toward CHANMODES ISUPPORT parameter for
dictating MODE parsing behavior.
* lisp/erc/erc-backend.el (erc--init-channel-modes, erc--update-modes,
erc-set-modes, erc-update-modes): Forward declarations, the last two
being removals.
(erc-server-MODE, erc-server-221): Use `erc--update-modes' instead of
`erc-update-modes'.
(erc-server-324): Use `erc--init-channel-modes' instead of
`erc-set-modes'.
* lisp/erc/erc-common.el (erc--channel-mode-types): New struct for
stashing processed \"CHANMODES\" data for the current server.
* lisp/erc/erc.el (erc-channel-modes): Fix doc string.
(erc-set-initial-user-mode): Display a local notice when requesting
redundant user MODE operations.
(erc-set-modes, erc-parse-modes, erc-update-modes): Deprecate for
reasons explained in associated ERC-NEWS entry.
(erc--update-membership-prefix): New function, a helper for specifying
arguments to the rather unruly `erc-update-current-channel-member'.
(erc--channel-modes): New variable to record channel-mode state in a
hash table.
(erc--channel-mode-types): New variable and getter to stash
and retrieve server-local instance of the struct of the same name.
(erc--process-channel-modes): New function to parse channel-mode
changes, dispatch handlers for unary modes, and update the local
variables `erc-channel-modes' and `erc--channel-modes'.
(erc--user-modes): New local variable for remembering user modes per
server. New function of the same name, a "getter" for the variable.
(erc--parse-user-modes): New function to parse user modes only.
(erc--update-user-modes): New function to update and sort
`erc--user-modes'.
(erc--update-channel-modes): New function to replace much of
`erc-update-modes', currently a thin wrapper around
`erc--process-channel-modes' to ensure it updates status prefixes.
(erc--update-modes): New function to call appropriate mode-updating
function for the current buffer.
(erc--init-channel-modes): New function to update channel mode letters
without status prefixes.
(erc--handle-channel-mode): New generic function, a placeholder for an
eventual API to handle specific "unary" mode letters, meaning those
that specify a single parameter for setting or unsetting.
(erc-update-channel-limit): Update doc string and answer question
posed by ancient comment.
(erc-message-english-user-mode-redundant-add,
erc-message-english-user-mode-redundant-drop): New English catalog
messages.
* test/lisp/erc/erc-scenarios-base-chan-modes.el: New file.
* test/lisp/erc/erc-tests.el (erc-parse-modes,
erc--update-channel-modes, erc--update-user-modes, erc--user-modes,
erc--parse-user-modes): New tests.
* test/lisp/erc/resources/base/modes/chan-changed.eld: New test data
file. (Bug#67220)
* lisp/erc/erc-common.el (erc--parsed-prefix): New struct to help with
tasks that depends on the advertised "PREFIX" parameter.
* lisp/erc/erc.el (erc-parse-prefix): Rework slightly for readability.
(erc--parsed-prefix): New variable and function of the same name for
caching the reversed result of `erc-parse-prefix' locally per server.
(erc-channel-receive-names): Use value stored in `erc--parsed-prefix'.
* test/lisp/erc/erc-tests.el (erc-with-server-buffer): Only activate
spy around actual test case forms.
(erc--parse-prefix): New test. (Bug#67220)
* lisp/erc/erc.el (erc-cmd-SQUERY): Set symbol property
`do-not-parse-args' to t so additional command-line arguments aren't
parsed but rather included as part of the function's lone (raw) LINE
parameter. (Bug#67209)
Copyright-paperwork-exempt: yes
* doc/misc/erc.texi: Add entry for `command-indicator' to Modules
chapter.
* etc/ERC-NEWS: Mention new module `command-indicator'.
* lisp/erc/erc-goodies.el (erc-noncommands-list): Replace the
nonexistent `erc-cmd-SMV' with function `erc-cmd-SAY'.
(erc-noncommands-mode, erc-noncommands-enable,
erc-noncommands-disable): Deprecate this module because it's a no-op.
(erc-command-indicator-face, erc-command-indicator): Migrate from main
library.
(erc-command-indicator-mode, erc-command-indicator-enable,
erc-command-indicator-disable): New module to take the spiritual place
of `noncommands'.
(erc-command-indicator): Move function here from main library, along
with option namesake mentioned above.
(erc-command-indicator-toggle-hidden): New command to toggle echoed
command-line visibility.
(erc--command-indicator-permit-insertion): New function.
(erc--command-indicator-display): New function, a slightly revised
version of the old `erc-display-command' from the main library. Its
only call site was removed back in d1036d288d "backport: erc
bugfixes". However, references were left behind to associated assets,
like `erc-command-indicator', etc. The function was later commented
out in 0c599ee2e2 "* lisp/erc/erc.el: Use `run-hook-with-args` for
`erc-pre-send-functions`", and then removed by a63ed6f78a "Remove
duplicate ERC prompt on reconnect".
* lisp/erc/erc-match.el (erc-match-toggle-hidden-fools): Use new
non-module-specific name for `erc-match--toggle-hidden'.
(erc-match--toggle-hidden): Move to main library for shared use by
other modules.
* lisp/erc/erc.el (erc-hide-prompt): Leave note explaining updated
role.
(erc-command-indicator): Move option and function of same name to
erc-goodies.
(erc-command-indicator-face): Move to erc-goodies.
(erc-modules): Remove module `noncommands' from standard value and
Custom set. Add `command-indicator' to set.
(erc--toggle-hidden): "New" function, a rebranded version of the
utility `erc-match--toggle-hidden' from erc-match.
(erc--send-input-lines): Accommodate modules wanting alternate
insertion functions.
(erc-load-irc-script-lines): Account for `erc-command-indicator' no
longer being defined in this library.
* test/lisp/erc/erc-scenarios-base-send-message.el
(erc-scenarios-base-send-message--command-indicator): New test.
* test/lisp/erc/erc-tests.el (erc-tests--modules): Remove
deprecated module `noncommands' from manifest. (Bug#67031)
* lisp/erc/erc.el (erc--msg-props): Reformat doc string to improve
readability.
(erc-send-current-line): Don't bind `erc--msg-prop-overrides' because
doing so affects all scoped calls to `erc-display-message' made by
slash commands, etc. and makes handling overly complex and error
prone.
(erc-display-msg): Set `erc-msg' property to `msg' instead of `self'
because the only legitimate use of this function is for inserting
"echoed" prompt input. (Bug#60936 and Bug#67031)
* lisp/erc/erc.el (erc--allow-empty-outgoing-lines-p): New internal
variable.
(erc-send-input-line, erc--run-send-hooks): Don't pad output when
`erc--allow-empty-outgoing-lines-p' is non-nil. (Bug#67031)
* lisp/erc/erc.el (erc--send-action-function): New function-valued
variable for locally advising `erc-send-action' so that built-in
modules can elect to handle insertion and sending themselves.
(erc-send-action): Defer to `erc--send-action-function'.
(erc--send-action-perform-ctcp): Isolate the message-sending business
for CTCP ACTIONs that used to reside in `erc-send-action'.
(erc--send-action-display): Isolate the message-insertion business
formerly residing in `erc-send-action' for more granular use. Fix a
minor bug involving inserted representations of CTCP ACTIONs not
having `erc-my-nick-face' applied to the speaker.
(erc--send-action): Perform the same displaying and sending of CTCP
ACTION messages formerly handled by `erc-send-action', but display
messages before sending them.
(erc--current-line-input-split): New variable bound to the post-review
`erc--input-split' object for the extent of display processing. This
mainly benefits slash-command handlers and the utility functions they
employ, such as `erc-send-message'.
(erc-cmd-SAY): Defer to `erc--send-message'.
(erc--send-message-nested-function): New function-valued variable
supporting an internal interface for influencing how
`erc-send-message' inserts and sends prompt input. Some handlers for
slash commands, like /SV, use `erc-send-message' to perform their own
insertion and sending, which is normally the domain of
`erc-send-current-line'. When this happens, modules can't easily
leverage the normal hook-based API to do things like suppress
insertion but allow sending or vice-versa. This variable provides an
internal seam for modules to exert such influence.
(erc-send-message): Behave specially when called by the default
interactive client via `erc-send-current-line' and friends.
(erc--send-message-external): New function to house the former body of
`erc-send-message', for third-party code needing to apply the
traditional behavior.
(erc--send-message-nested): New function for turning arbitrary text,
such as replacement prompt input, into outgoing message text by doing
things like ensuring "send" hooks run and invariants for prompt
markers are preserved.
(erc--make-input-split): New helper function for creating a standard
`erc--input-split' object from a string. This is arguably less
confusing than adding another constructor to the struct definition.
(erc-send-current-line): Bind `erc--current-line-input-split' when
dispatching prompt-input handlers. Use helper `erc--make-input-split'
to initialize working `erc--input-split' state object.
(erc--run-send-hooks): Honor existing `refoldp' slot from
`erc--input-split' object.
(erc--send-input-lines): Convert to generic function to allow modules
control over fundamental insertion and sending operations, which is
necessary for next-generation features, like multiline messages.
(erc-modes): Don't output non-modules. That is, only list actual
modules created via `define-erc-module', and `quote' members of the
resulting list.
* test/lisp/erc/erc-scenarios-base-send-message.el: New test file.
* test/lisp/erc/resources/base/send-message/noncommands.eld: New data
file. (Bug#67031)
* lisp/erc/erc-backend.el (erc--server-propagate-failed-connection):
Include leading three-asterisk notice prefix when reporting process
exit status, and set the `erc-msg' text property to `notice-error'.
(erc-schedule-reconnect): Include leading notice prefix when inserting
`reconnecting' message.
* lisp/erc/erc.el (erc-process-input-line, erc-cmd-PART,
erc-cmd-TOPIC): Display `no-target' messages as "error notices".
(erc-message-english-disconnected,
erc-message-english-disconnected-noreconnect): Hard-code standard
value of `erc-notice-prefix' into message text for consistency during
formatting and insertion.
* test/lisp/erc/erc-tests.el (erc--refresh-prompt): Expect notice
prefix before `no-target' message. (Bug#67031)
* lisp/erc/erc-stamp.el
(erc-stamp--insert-date-stamp-as-phony-message): Ensure existing
user markers aren't displaced by date-stamp insertion.
* lisp/erc/erc.el (erc--insert-line-function): New function-valued
variable for overriding `insert'.
(erc-insert-line): Call `erc--insert-line-function', when non-nil, to
insert line specially.
* test/lisp/erc/erc-scenarios-stamp.el
(erc-scenarios-stamp--on-insert-modify): New assertion helper
function.
(erc-scenarios-stamp--date-mode/left-and-right): New test.
(Bug#60936)
* lisp/erc/erc.el (erc--get-inserted-msg-bounds): Account for
`previous-single-property-change' returning a position adjacent to
that with an actual changed value. The prior attempt at addressing
this was insufficient.
* test/lisp/erc/erc-tests.el (erc--get-inserted-msg-bounds): New test.
; * test/lisp/erc/resources/base/local-modules/second.eld: Timeout.
; * test/lisp/erc/resources/base/local-modules/third.eld: Timeout.
* lisp/erc/erc-fill.el (erc-fill--spaced-commands): Remove unused
internal variable originally intended for ERC 5.6.
(erc-fill): Check for `erc-msg' being `msg', which carries the same
meaning as `erc-cmd' being `PRIVMSG' or `NOTICE', except that inserted
outgoing messages now no longer normally have an `erc-cmd' property.
(erc-fill-wrap-mode, erc-fill-wrap-disable): Kill
`erc-fill--wrap-last-msg'.
(erc-fill--wrap-max-lull): Convert from buffer-local to normal
variable.
(erc-fill--wrap-continued-message-p): Rework slightly to guard against
resetting the "last speaker" marker when the `erc-ephemeral' text
property is present. This tells insert- and send-related hook members
to pretend the current message doesn't exist when performing stateful
operations. That is, modules should expect the message being inserted
to possibly disappear or be replaced. Also, look for `erc-msg' being
`msg' instead of `erc-cmd' being `PRIVMSG', and fix bug involving only
checking `erc-ctcp' in the current message.
* lisp/erc/erc-stamp.el (erc-add-timestamp): Don't insert timestamps
when the `erc-ephemeral' text property is present.
* lisp/erc/erc.el (erc--msg-props): Add doc string explaining the
purpose of this variable and the various text properties most commonly
present in its value.
(erc--msg-prop-overrides): Add doc string.
(erc-send-action): Don't set `erc-cmd' prop on outgoing CTCP ACTIONs.
(erc-display-message): Reverse overrides to prefer items toward the
front of the alist.
(erc-process-ctcp-query): Include existing overrides from environs.
(erc-send-current-line): Include existing overrides from environs.
(erc-display-msg): Fix doc string and reverse overrides.
* test/lisp/erc/erc-fill-tests.el (erc-fill-tests--insert-privmsg):
Remove stray comment.
(erc-fill-tests--save-p): Set value from environment variable.
(erc-fill-tests--compare): Limit writing snapshots to one test at a
time.
(erc-fill-wrap--merge-action): Fix expected output for non-action
messages that follow action messages. These were previously merged
but escaped detection.
* test/lisp/erc/resources/fill/snapshots/merge-wrap-01.eld: Update.
(Bug#60936)
* lisp/erc/erc-stamp.el (erc-stamp--propertize-left-date-stamp): Run
`erc-stamp--insert-date-hook' separately here instead of via
`erc-insert-modify-hook'.
(erc-stamp--insert-date-stamp-as-phony-message): Don't include value
of `erc-stamp--insert-date-hook' in let-bound `erc-insert-modify-hook'
because its members can run twice if buffer-local. Remove
`erc-send-modify-hook' because it only runs via `erc-display-msg'.
Shadow "pre" and "done" hooks because they don't expect to run in a
narrowed buffer. Call getter for `erc-stamp--current-time'.
(erc-stamp--lr-date-on-pre-modify,
erc-insert-timestamp-left-and-right): Use function form of
`erc-stamp--current-time' for determining current time stamp.
* lisp/erc/erc.el (erc--get-inserted-msg-bounds): Fix off-by-one like
thinko.
(erc--traverse-inserted): Create temporary marker when END is a buffer
position so that insertions and deletions are accounted for in
the terminating condition.
(erc--delete-inserted-message): New function.
* test/lisp/erc/erc-tests.el (erc--delete-inserted-message): New test.
(erc--update-modules/unknown): Improve readability slightly.
* test/lisp/erc/resources/erc-d/erc-d-t.el (erc-d-t-make-expecter):
Indicate assertion flavor in error message. (Bug#60936)
* 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)
* 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.
(Bug#66578)
* 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.
; * test/lisp/erc/resources/fill/snapshots/merge-01-start.eld: Update.
; * test/lisp/erc/resources/fill/snapshots/merge-02-right.eld: Update.
; * test/lisp/erc/resources/fill/snapshots/merge-wrap-01.eld: Update.

; * test/lisp/erc/resources/fill/snapshots/stamps-left-01.eld: Update.
(Bug#60936)
* 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.

(Bug#60936)
* lisp/erc/erc.el (erc--remove-from-prop-value-list): New function for
removing `invisible' and `face' prop members cleanly.
* test/lisp/erc/erc-tests.el (erc--remove-from-prop-value-list,
erc--remove-from-prop-value-list/many): New tests. (Bug#60936)
* etc/ERC-NEWS: Add entry for `erc-remove-parsed-property'.
* lisp/erc/erc.el (erc-remove-parsed-property): Deprecate option
because the potential for inadvertent self harm outweighs the
potential benefits. Additionally, replicating this functionality via
hooks is trivial.
(erc-display-line-1): Remove quasi-deprecated `tags' property because
the preferred format for `erc-response.tags' has changed, and ERC has
never supported IRCv3 tags.
* lisp/erc/erc-backend.el (erc-server-JOIN): Let `erc-display-message'
handle formatting instead of baking out a string. The text ultimately
inserted remains unchanged, but forwarding the original `format-spec'
arguments now has the side effect of influencing text properties, which
conveys richer meaning for modules to act upon when doing things like
deciding whether to hide a given message.
* lisp/erc/erc.el (erc-cmd-IGNORE, erc-cmd-UNIGNORE,
erc--unignore-user, erc-cmd-IDLE, erc-cmd-BANLIST, erc-cmd-MASSUNBAN):
Use `erc-display-message' with `notice' for the TYPE parameter instead
of composing `erc-make-notice' and `erc-display-line'.
* 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)
