* lisp/gnus/nnselect.el (nnselect-push-info): Restrict updating of
marked articles to those whose headers have been retrieved, taking
care to handle 'tuples.
* lisp/gnus/nnselect.el (nnselect-push-info): The current list of read
articles should be computed from the summary buffer local variables,
not from the group info.
* lisp/gnus/nnselect.el (nnselect-push-info): Don't try to propagate
info to component groups if gnus-newsgroup-selection is nil.
* lisp/gnus/nnselect.el (nnselect-request-update-info): Don't update
the nnselect group info if gnus-newsgroup-selection is nil.
* lisp/gnus/gnus-group.el (gnus-group-get-new-news-this-group):
* lisp/gnus/gnus-group.el (gnus-get-unread-articles-in-group): Update
the current value of the active range since it might have changed.
* lisp/progmodes/project.el (project-prefixed-buffer-name):
Use project-name to calculate prefixed buffer name (bug#62548).
(project-compilation-buffer-name-function): Update doc.
Simplify function and now also consider individual parameter
documentation strings, which typescript-language-server seems to
provide.
* lisp/progmodes/eglot.el (eglot--sig-info): Rework.
* lisp/erc/erc.el (erc-reuse-frames): Add alternate value to favor
existing frames already displaying buffers from the same connection.
(erc--setup-buffer-first-window, erc--display-buffer-use-some-frame):
Add helpers to support 'display' variant of `erc-resuse-frames'
* test/lisp/erc/erc-tests.el (erc-tests--run-in-term,
erc-tests--servars, erc-reuse-frames, erc-tests--erc-reuse-frames,
erc-tests--erc-reuse-frames--t, erc-resuse-frames--t,
erc-tests--erc-reuse-frames--displayed-single,
erc-reuse-frames--displayed-single, erc-tests--assert-server-split,
erc-tests--erc-reuse-frames--displayed-double,
erc-reuse-frames--displayed-double,
erc-tests--erc-reuse-frames--displayed-full,
erc-reuse-frames--displayed-full): Add test case and supporting
fixtures. (Bug#55540.)
* lisp/erc/erc-common.el: (erc-with-server-buffer): Modify slightly to
use `buffer-local-value' when possible.
* test/lisp/erc/erc-services-tests.el
(erc-services-tests--auth-source-plstore-standard-entries,
erc-services-tests--auth-source-plstore-standard-secrets): Remove
unused variables.
(erc-services-tests--auth-source-plstore-standard-announced): Add new
var to hold common plstore document.
(erc--auth-source-search--plstore-standard,
erc--auth-source-search--plstore-announced,
erc--auth-source-search--plstore-overrides): Use string literals for
text-document content.
(erc-services-tests--auth-source-json-standard-entries): Remove unused
variable.
(erc-services-tests--auth-source-json-standard-announced): Add new
variable.
(erc--auth-source-search--json-standard,
erc--auth-source-search--json-announced,
erc--auth-source-search--json-overrides): Use string literals for
text-document content.
(erc-services-tests--secrets-search-items): Add new helper function.
(erc--auth-source-search--secrets-standard,
erc--auth-source-search--secrets-announced,
erc--auth-source-search--secrets-overrides): Use helper to mock
`secrets-search-items' instead of misleading lambda.
* lisp/erc/erc-tests.el (erc-with-server-buffer): Add test.
* lisp/erc/erc-button.el (erc-button-mode, erc-button-enable): Warn if
`erc-button-alist' contains deprecated FORM field in `nicknames'
entry.
(erc-button-alist): Discourage arbitrary sexp form for third item of
entries and offer more useful bounds-modifying function in its place.
Mention that anything other than `erc-button-buttonize-nicks' is
deprecated as the FORM field in a `nicknames' entry. Bump
package-version even though this doesn't introduce a visible change in
the default value.
(erc-button--maybe-warn-arbitrary-sexp): Add helper for validating
third `erc-button-alist' field.
(erc-button--check-nicknames-entry): Add helper to check for
deprecated items in `erc-button-alist'.
(erc-button--preserve-bounds): Add function to serve as default value
for `erc-button--modify-nick-function).
(erc-button--modify-nick-function): Add new variable to hold a
function that filters nickname bounds when buttonizing.
(erc-button--phantom-users, erc-button--add-phantom-speaker,
erc-button--phantom-users-mode): Add new internal minor mode for
treating unseen speakers of PRIVMSGs as known members of the server
for things like coloring nicks during buffer playback.
(erc-button--get-user-from-speaker-naive): Add temporary utility
function to scrape nick from speaker in narrowed buffer. This will be
replaced by an account-aware version in next major ERC release.
(erc-button-add-nickname-buttons): Accommodate function variant for
"form" field of `erc-button-alist' entries. Minor optimizations.
This function will likely become the primary juncture for applying
text properties that support nickname-related user-intelligence
features.
(erc-button-add-buttons-1): Show warning when arbitrary sexp for third
"form" field encountered. Accommodate binary function instead.
(erc-button--substitute-command-keys-in-region): Add helper function
for applying key substitutions in ERC warning messages.
(erc-button--display-error-notice-with-keys): Add new helper function
for displaying ad hoc warnings that possibly require key substitution.
(erc-button--display-error-notice-with-keys-and-warn): Add variant of
`erc-button--display-error-notice-with-keys' that also emits warnings.
* lisp/erc/erc-networks.el (erc-networks--ensure-announced,
erc-networks--on-MOTD-end): Use new key-substitutions helper from
erc-button.
* test/lisp/erc/erc-tests.el
(erc-button--display-error-notice-with-keys): New test.
* test/lisp/erc/resources/base/assoc/bouncer-history/foonet.eld: Add
unknown speaker in channel for phantom store to handle. Currently
requires manual intervention to leverage. (Bug#60933.)
* lisp/erc/erc-fill.el (erc-fill-function): Add new value
`erc-fill-wrap'.
(erc-fill-static-center): Extend meaning of option to also affect
`erc-wrap-mode'.
(erc-fill--wrap-value, erc-fill--wrap-visual-keys): New variables to
support new local module.
(erc-fill-wrap-visual-keys): New option to control how and where
`visual-line-mode' keys are active.
(erc-fill-wrap-merge): Add option for omitting a speaker's name if
they just now spoke. Enabled by default.
(erc-fill--wrap-move): New helper function for fill-wrap movement
commands.
(erc-fill--wrap-kill-line, erc-fill--wrap-beginning-of-line,
erc-fill--wrap-end-of-line): New movement commands.
(erc-fill-wrap-cycle-visual-movement): New command to cycle local
copy of `erc-fill-wrap-visual-keys'.
(erc-fill-wrap-mode-map): New keymap based on `visual-line-mode-map'.
(erc-fill--make-module-dependency-msg): Helper for
`erc-fill-wrap-enable'.
(erc-fill-wrap-mode, erc-fill-wrap-enable, erc-fill-wrap-disable): New
local module.
(erc-fill--wrap-length-function): Internal interface in the form of a
function variable for other modules to control the fill-wrap overhang.
(erc-fill--wrap-last-msg, erc-fill--wrap-max-lull,
erc-fill--wrap-continued-message-p): Add items to support hiding of
redundant speaker names in consecutive messages.
(erc-fill--wrap-stamp-insert-prefixed-date): New function to add
`line-prefix' property to inserted date stamp.
(erc-fill-wrap): New function implementing the
`erc-fill-function' (behavioral) interface.
(erc-fill--wrap-fix): New, possibly temporary function for other
modules to fix misalignment caused by fill-wrap.
(erc-fill-wrap-nudge, erc-fill--wrap-nudge): New command and helper
for growing and shrinking visual fill prefix.
* test/lisp/erc/erc-fill-tests.el: New file. (Bug#60936.)
* test/lisp/erc/resources/fill/snapshots/merge-01-start.eld: New file.
* test/lisp/erc/resources/fill/snapshots/merge-02-right.eld: New file.
* test/lisp/erc/resources/fill/snapshots/monospace-01-start.eld: New file.
* test/lisp/erc/resources/fill/snapshots/monospace-02-right.eld: New file.
* test/lisp/erc/resources/fill/snapshots/monospace-03-left.eld: New file.
* test/lisp/erc/resources/fill/snapshots/monospace-04-reset.eld: New file.
* lisp/erc/erc-match.el (erc-match-mode, erc-match-enable,
erc-match-disable): Arrange for possibly adding or removing
`erc-match' from `buffer-invisibility-spec'.
(erc-match--hide-fools-offset-bounds): Add new variable to serve as
switch for activating invisibility on a modified interval that's
offset toward `point-min' by one character.
(erc-hide-fools): Optionally offset start and end of invisible region
by minus one.
(erc-match--modify-invisibility-spec): New housekeeping function to
set up and tear down offset spec. (Bug#60936.)
* lisp/erc/erc-fill.el (erc-fill-mode, erc-fill-enable,
erc-fill-disable): Use API to create these.
(erc-fill-static): Save restriction instead of caller's match
data. (Bug#60936.)
* lisp/erc/erc-log.el (erc-log-filter-function): Add new value
`erc-stamp-prefix-log-filter'.
* lisp/erc/erc-stamp.el (erc-timestamp-use-align-to): Enhance meaning
of option to accept numeric value for dynamically aligned right-hand
stamps. Use `graphic-display-p' to determine default value even
though, as stated in the manual, terminal Emacs also supports the
"space" display spec.
(erc-stamp-right-margin-width): New option to determine width of right
margin when `erc-stamp--display-margin-mode' is active or
`erc-timestamp-use-align-to' is set to `margin'.
(erc-stamp--display-margin-force): Add new helper function for
`erc-stamp--display-margin-mode'.
(erc-stamp--adjust-right-margin): New function to adjust width of
right margin.
(erc-stamp-prefix-log-filter): New value for `erc-log-filter-function'
compatible with modules that activate
`erc-stamp--display-margin-mode'.
(erc-stamp--display-margin-mode): Add internal minor mode to help
other modules quickly ensure left-right, display-prop-oriented stamps
are showing correctly. Does not support left-hand-only stamps.
(erc-insert-aligned): Deprecate function and remove from primary
client code path.
(erc-stamp--inherited-props): Add internal constant to hold properties
that should be inherited from any stamp-bearing message being
inserted.
(erc-insert-timestamp-right): Account for new display-related values
of `erc-timestamp-use-align-to'.
* test/lisp/erc/erc-stamp-tests.el (erc-timestamp-use-align-to--nil,
erc-timestamp-use-align-to--t): Adjust spacing for new default
right-hand stamp, `erc-format-timestamp', which lacks a leading space.
(erc-timestamp-use-align-to--integer,
erc-timestamp-use-align-to--margin): New tests. (Bug#60936.)
* lisp/erc/erc-stamp.el (erc-timestamp-format-right): Deprecate option
and change meaning of its nil value to fall through to
`erc-timestamp-format'. Do this to allow modules to predict what the
right-hand stamp's final width will be. This also saves
`erc-insert-timestamp-left-and-right' from calling
`erc-format-timestamp' again for every inserted message.
(erc-stamp-mode, erc-stamp-enable, erc-stamp-disable): Add
`erc-stamp--recover-on-reconnect' to `erc-mode-hook'.
(erc-stamp--recover-on-reconnect): Add function to reuse last values
of `erc-timestamp-last-inserted' and friends to avoid reprinting
stamps when reconnecting.
(erc-stamp--current-time): Add new generic function and method to
return current time. Default to calling `erc-current-time'. Also add
new internal variable of the same name to hold time value used to
construct formatted stamps passed to `erc-insert-timestamp-function'.
(erc-add-timestamp): Bind `erc-stamp--current-time' when calling
`erc-insert-timestamp-function'.
(erc-stamp--insert-date-function): New variable for modules to tweak
date-insertion.
(erc-insert-timestamp-left-and-right): Use STRING parameter and favor
it over the now deprecated `erc-timestamp-format-right' to avoid
formatting twice. Also extract current time from the variable
`erc-stamp--current-time' for similar reasons. And defer to
`erc-stamp--insert-date-function' to insert left stamp. (Bug#60936.)
(erc-stamp--tz): New internal variable.
(erc-format-timestamp): Pass `erc-stamp--tz' as time-zone to
`format-time-string'.
* lisp/erc/erc-stamp.el (erc-add-timestamp): Add new text property
`erc-timestamp' to store lisp time object formerly ensconced in a
closure. Instead of creating a new lambda for the cursor-sensor
function of each message in a buffer, leave a gap between messages to
trip the sensor function. The motivation behind this change is to
allow third parties access to valuable timestamp data already stored
by ERC anyway. Of secondary importance is discouraging the reliance
on those lambdas as a means of detecting message bounds. The gap now
serves a similar purpose. Basically, the final character in a
message, a newline, will not have a timestamp or a sensor function.
In the rare instance the stamps module isn't loaded, the new
`erc-command' property can be used for this purpose instead. Also,
instead of looking for the `invisible' text property at point, which
is normally `point-max' and thus outside the accessible portion of the
buffer, look at the beginning of the inserted message. This allows
hook members running before this function to opt out of timestamps by
marking a message as invisible.
(erc-echo-timestamp): Make interactive and show timestamps even when
the variable `erc-echo-timestamps' is nil.
(erc--echo-ts-csf): Add new function to serve as value of
cursor-sensor function text properties.
* test/lisp/erc/erc-stamp-tests.el: New file. (Bug#60936.)
* lisp/erc/erc.el (erc-display-message): Replace `rear-sticky' text
property, which has been around since 2002, with a more useful
`erc-command' property. It records the current IRC command as a
symbol or a number, in the case of numerics.
(erc--own-property-names, erc--remove-text-properties) Add variable
and internal helper function for filtering values returned by
`filter-buffer-substring-function'.
(erc-display-prompt): Make the `field' text property more meaningful
to aid in searching, although this makes the `erc-prompt' property
somewhat redundant.
(erc-put-text-property, erc-list): Alias these to subr functions.
(erc-restore-text-properties): Don't forget tags when restoring.
(erc--get-eq-comparable-cmd): New function to extract commands for use
as more easily searchable text-property values. (Bug#60936.)
* lisp/erc/erc.el (erc--initialize-markers): New helper to ensure
prompt and its associated markers are set up correctly.
(erc-open): When determining whether a session is a logical
continuation, leverage the work already performed by the
`erc-networks' library to that effect. Its verdicts are based on
network context and thus reliable even when a user dials anew from an
entry-point, which is not a simple reconnection because the user
expects a clean slate for everything except an existing buffer's
messages, meaning `erc--server-reconnecting' will be nil and
local-module state variables need resetting. Also remove the check
for `erc-reuse-buffers' and instead trust that `erc-get-buffer-create'
always does the right thing. Replace all code involving marker and
prompt setup by deferring to a new helper, `erc--initialize markers'.
* test/lisp/erc/erc-scenarios-base-local-module-modes.el: New file.
* test/lisp/erc/erc-scenarios-base-local-modules.el
(erc-scenarios-base-local-modules--mode-persistence): Move test to
separate file to help with parallel "-j" runs.
* test/lisp/erc/erc-tests.el (erc-tests--send-prep): Replace
redundant prompt-setup code.
(erc--initialize-markers): New test. (Bug#60936.)
* lisp/erc/erc.el (erc--assert-input-bounds): Add possibly temporary
helper function to sync `process-mark' to `erc-insert-marker' in
server buffer.
(erc-display-line-1): Expect `erc-insert-marker' to always be
initialized. Assert some essential invariants regarding insert
markers.
(erc-send-current-line): Delete typed input but not the prompt.
(erc-display-msg): Rework slightly to respect existing markers.
* test/lisp/erc/erc-dcc-tests.el
(erc-dcc-tests--dcc-handle-ctcp-send): Set insert marker.
* test/lisp/erc/erc-networks-tests.el
(erc-networks--rename-server-buffer--existing-live): Initialize
markers to appease `erc--assert-input-bounds'.
* test/lisp/erc/erc-tests.el (erc-ring-previous-command): Fix sloppy
mock. (Bug#60936.)
* lisp/erc/erc-goodies.el (erc-keep-place-indicator-style,
erc-keep-place-indicator-buffer-type,
erc-keep-place-indicator-follow): New options for anchoring kept place
visually.
(erc-keep-place-indicator-line, erc-keep-place-indicator-arrow): New
faces.
(erc--keep-place-indicator-overlay): New internal variable.
(erc--keep-place-indicator-on-window-configuration-change): New
function to subscribe to `window-configuration-change-hook' and maybe
update kept-place indicator.
(erc--keep-place-indicator-setup): New function to initialize buffer
for local module `keep-place-indicator'.
(erc-keep-place-indicator-mode, erc-keep-place-indicator-enable,
erc-keep-place-indicator-disable): New local ERC module. Depends on
"parent" module `keep-place'. Like `fill-wrap', this is (for now)
also deliberately left out of the widget menu for `erc-modules'.
(erc-keep-place-move, erc-keep-place-goto): Add new commands for
manually updating and jumping to keep-place indicator.
(erc-keep-place): Move `erc--keep-place-overlay' when applicable.
* test/lisp/erc/erc-goodies-tests.el (erc-keep-place-indicator-mode):
Add test.
(Bug#59943.)
* doc/misc/erc.texi: Update statement about availability of `:user'
keyword param when entry points called interactively.
* lisp/erc/erc/compat.el: Don't require `url-parse' when compiling.
Add forward declaration for `url-type'.
* lisp/erc/erc.el: Don't require `url-parse' when compiling. Add
forward declarations for accessors of `url' struct from `url-parse'
library.
(erc-select-read-args): Allow optionally calling entry points with a
prefix arg to access params `user' and `:full-name'.
(erc-tls): Update doc string.
* test/lisp/erc/erc-tests.el (erc-select-read-args): Add test for
extra args. (Bug#60428.)
* lisp/erc/erc.el (erc-buffer-display, erc-receive-query-display):
Add aliases for `erc-join-buffer' and `erc-auto-query'.
(erc-interactive-display): Add new option to control display of server
buffers during interactive entry-point invocations.
(erc-select-read-args): Pass `erc-interactive-display' to entry
points.
* test/lisp/erc/erc-tests.el (erc-select-read-args): Expect
buffer-display values from `erc-interactive-display'.
(erc-tls, erc--interactive): Also check `erc-join-buffer' in
environment when `erc-open' called. (Bug#60428.)
* lisp/erc/erc.el (erc--warn-unencrypted): Remove unused internal
function.
(erc-select-read-args): Offer to use TLS when user runs M-x erc and
opts for default server and port or provides the well-known IANA TLS
port or enters an ircs:// URL at the server prompt. For the last two,
do this immediately instead of calling `erc-tls' interactively and
imposing a review of just-chosen values. Also remove error warnings
and ensure `erc-tls' still works by setting
`erc-server-connect-function' to `erc-open-tls-stream' when
appropriate. Include the word "URL" in server prompt.
(erc--with-entrypoint-environment): Add new macro for empowering an
entry point's interactive form to bind special variables in their
command's body without shadowing them in the lambda list.
(erc, erc-tls): Add internal keyword argument for interactive use, but
don't make it `keywordp' or advertise its presence. Also use new
helper macro, `erc--with-entrypoint-environment', to temporarily bind
special vars given by interactive helper `erc-select-read-args'.
* test/lisp/erc/erc-tests.el (erc--with-entrypoint-environment): Add
new test.
(erc-select-read-args): Modify return values to expect additional
internal keyword argument where appropriate.
(erc-tls): Make assertions about environment.
(erc--interactive): New test. (Bug#60428.)
* lisp/erc/erc-track.el (erc-track--switch-buffer): If the chosen
buffer has been killed, remove it from `erc-modified-channels-alist'
and try again.
* test/lisp/erc/erc-scenarios-misc.el
(erc-scenarios-base-kill-server-track): New test. (Bug#60560.)
* lisp/erc/erc-common.el (erc--fill-module-docstring): Add helper to
fill doc strings.
(erc--assemble-toggle, define-erc-module): Use helper to fill doc
string.
* test/lisp/erc/erc-tests.el (define-minor-mode--global,
define-minor-mode--local): Adjust expected output for generated doc
strings. (Bug#60935.)
* lisp/erc/erc-common.el: (erc--inside-mode-toggle-p): Add global var
to inhibit mode toggles from being run by `erc-update-modules'. It
must be non-nil inside custom-set functions for mode toggles created
by `define-erc-module'.
(erc--favor-changed-reverted-modules-state): Add new helper to show a
"SET" Custom state for `erc-modules' except when reverting to the
default value because \"STANDARD\" always takes precedence, as
explained somewhat in bug#12864.
(erc--assemble-toggle): Don't modify `erc-modules' when run from
custom-set function.
(erc--neuter-custom-variable-state): Add new function to serve as a
phony getter that deceives Customize into thinking the variable is
always set to its standard value. The justification for this is that
toggling a module's minor mode in Customize has never worked and has
only sewn confusion in new users. Without this hack, mode widgets
show a state of "CHANGED outside Customize", which alone is probably
preferable, except that they all end up toggled open, bringing them
unwanted attention and distracting the user.
(erc--tick-module-checkbox): Add helper to toggle the appropriate
checkbox in the `erc-modules' widget when a user interactively toggles
a minor-mode state variable.
(erc--prepare-custom-module-type): Create spec for minor-mode Custom
`:type', deferring various aspects until module-definition time.
(define-erc-module): Add `:get' and `:type' keywords to be passed to
`defcustom' definition for global modules.
* lisp/erc/erc.el (erc-modules): Inhibit `erc-update-modules' when run
from a minor-mode toggle's custom-set function.
* test/lisp/erc/erc-tests.el (define-erc-module--global,
define-erc-module--local): Update `erc-modules' mutations with
`erc--inside-mode-toggle-p' guard conditions. (Bug#60935.)
* lisp/erc/erc-capab.el: Add property crutch to help ERC find module's
Custom group.
* lisp/erc/erc-common.el (erc--find-group): Add new function, a helper
for finding an existing ERC module's Custom group based on
`define-erc-module' params. Prefer `group-documentation' as a
sentinel over symbol properties owned by Customize because they might
not be present if the group isn't yet associated with any custom
variables.
(define-erc-module): Set `:group' keyword value more accurately,
falling back to `erc' when no associated group has been defined.
* test/lisp/erc/erc-tests.el (erc--find-group, erc--find-group--real):
New tests.
(define-erc-module--global, define-erc-module--local): Expect the
`:group' keyword to be the unevaluated `erc--find-group'
form. (Bug#60935.)
* lisp/erc/erc-goodies.el: Don't add Imenu hooks to `erc-mode-hook' at
top level. Remove autoload for `erc-create-imenu-index' because it
already exists in the `erc-imenu' library.
(erc-imenu-setup): Move to the erc-imenu library.
* lisp/erc/erc-imenu.el (erc-unfill-notice): Allow modifications to
read-only text. Thanks to Yusef Aslam for reporting this bug.
(erc-imenu-setup): Move here from goodies.
(erc-imenu--create-index-function): New helper var to hold previous
local value of `imenu-create-index-function'. Perhaps advice should
be used instead, but a cursory search of the Emacs code base reveals
no such usage.
(erc-imenu-mode, erc-imenu-enable, erc-imenu-disable): Create "new"
ERC module for Imenu integration.
* lisp/erc/erc.el (erc-modules): Add `imenu' to default value and
create widget menu item. Update package-version.
* test/lisp/erc/erc-tests.el (erc-tests--modules): Add
`imenu'. (Bug#60954)
* lisp/erc/erc-goodies.el (erc-spoiler-face): Add new face.
(erc--controls-additional-colors): Add remaining 16-99 colors.
(erc-get-bg-color-face, erc-get-fg-color-face): Look up extended
colors in table.
(erc-controls-remove-regexp, erc-controls-highlight-regexp): Convert
to `rx' forms and move above first use to eliminate intra-file forward
declarations.
(erc-controls-propertize): Support spoilers.
* test/lisp/erc/erc-goodies-tests.el: New file. (Bug#60954.)
* lisp/erc/erc-button.el (erc-button-mode, erc-button-enable,
erc-button-disable): Replace call to `erc-button-setup' with one to
`erc--modify-local-map'. This means `erc-button-setup' is now dead
code from a client perspective.
* lisp/erc/erc-goodies.el (erc-irccontrols-enable,
erc-irccontrols-disable, erc-irccontrols-mode): Bind
`erc-toggle-interpret-controls' in module definition so it's only
available when the module is active.
* lisp/erc/erc-log.el (erc-log-mode, erc-log-enable, erc-log-disable):
Move top-level `define-key' into module definition.
* lisp/erc/erc-match.el (erc-match-mode, erc-match-enable,
erc-match-disable): Move top-level `define-key' into module
definition.
* lisp/erc/erc.el (erc-mode-map): Remove C-c C-c binding for
`erc-toggle-interpret-controls'.
(erc--modify-local-map): Add helper for global modules to use when
modifying `erc-mode-map'.
* test/lisp/erc/erc-tests.el (erc--modify-local-map): Add test.
Ensure modifications to `erc-mode-map' on loading `erc' and via
`erc-mode-hook' still work. (Bug#60954.)
* lisp/erc/erc-goodies.el: Obviate the need for forward declarations
by requiring `erc'. Add minor-mode autoloads for `scrolltobottom',
`readonly', `move-to-prompt', `keep-place', `noncommands',
`irccontrols', `smiley', and `unmorse'. Add Local variables footer
with `generated-autoload-file'.
(erc-controls-strip): Autoload this function.
* lisp/erc/erc-ibuffer.el: Require `erc-goodies' for
`erc-control-interpret'. The justification for the blanket `require'
is this module isn't a member of `erc-modules' by default.
* lisp/erc/erc-page.el: (erc-ctcp-query-PAGE): Require `erc-goodies'
and put forward declaration for `erc-control-interpret' atop file.
* lisp/erc/erc-speedbar.el: Require `erc-goodies' for the same reason
as erc-ibuffer.el.
* lisp/erc/erc.el: Remove `require' for `erc-goodies' at end of file
and `pp' at top of file because `pp-to-string' is autoloaded on Emacs
27. Also remove `require's for `thingatpt', `time-date', and
`iso8601'. They're all used sparingly and the latter two have only
been around for one major release, so their removal likely won't cause
much churn. And `thingatpt' already has a call-site `require', so the
top-level one is redundant, but autoload `word-at-point' anyway for
the benefit of third-party libraries like `hl-nicks'. Also wrap local
loaddefs `require' call in `eval-and-compile'.
(erc--read-time-period): Require dependencies. (Bug#60954.)
* lisp/erc/erc-common.el (erc--features-to-modules,
erc--modules-to-features, erc--module-name-migrations): Remove unused
internal functions.
(erc--normalize-module-symbol): Make aware of new migration scheme
based on symbol properties.
* lisp/erc/erc-page.el: Add autoload cookie for module migration.
* lisp/erc/erc-pcomplete.el: Add autoload cookies for module
migration.
* lisp/erc/erc-services.el: Add autoload cookie for module migration.
* lisp/erc/erc-sound.el: Add autoload cookie for module migration.
* lisp/erc/erc-stamp.el: Add autoload cookie for module migration.
* lisp/erc/erc.el (erc-modules): Reorder default value, sorted by
`string<' so that Customize does not consider the value to have been
edited. Remove non-existent module `hecomplete' from lineup and swap
a couple more to maintain sorted order. Change `:initialize' function
to tag all symbols for built-in modules with an `erc--module'
property. In the `:set' function, ensure third-party modules appear
after the sorted and normalized built-ins, but in user-defined order.
Do this to prevent all modules, built-ins included, from ending up as
populated form fields for the "other" checkbox in the Customize
interface.
(erc--find-mode): Add helper function for `erc--update-modules'.
(erc--update-modules): Always resolve module names and only
conditionally attempt to require corresponding features.
* test/lisp/erc/erc-tests.el (erc-tests--modules): Add manifest for
asserting built-in modules and features. This is easier to verify
visually than looking at the custom-type set for `erc-modules'.
(erc-modules--initialize): New test.
(erc-modules--internal-property): Add test.
(erc--normalize-module-symbol): New test.
(erc--find-mode): New test.
(erc--update-modules) Adapt to new paradigm and make more
comprehensive. (Bug#60954.)
* lisp/erc/erc-backend: (erc--get-isupport-entry): Replace call to
`erc-compat--with-memoization' with the built-in `with-memoization'.
* lisp/erc/erc-compat.el: (erc-compat-function, erc-compat-call): Add
new macros from Compat 29.1.2.0.
(erc-compat--with-memoization): Remove because it's now provided by
Compat. (Bug#60954.)
* lisp/erc/erc.el (erc-channel-p): Favor "CHANTYPES" ISUPPORT item
before falling back to well known prefixes.
* test/lisp/erc/erc-tests.el (erc-channel-p): Add test. Arbitrarily
bundled with bug#60954.
* lisp/erc/erc-backend.el (erc-server-reconnect-timeout): Mention
`erc-nickname-in-use-functions' in doc string.
* lisp/erc/erc.el (erc-nickname-in-use-functions,
erc-regain-nick-on-connect): Add abnormal hook and possible value to
handle stale connections preventing a desired nick from being reissued
by the server. Follows directly from bug#62044.
(erc-nickname-in-use): Call `erc-nickname-in-use-functions'.
* test/lisp/erc/erc-scenarios-base-renick.el
(erc-scenarios-base-renick-auto-regain): New test.
* test/lisp/erc/resources/base/renick/regain/normal-again.eld: New file.
* test/lisp/erc/resources/base/renick/regain/normal.eld: New file.
* lisp/erc/erc-backend.el (erc-server-reconnect-timeout): Replace
questionable claim with recommendation for alternate value when
experiencing nick rejections.
(erc-server-reconnect-function): Add new, somewhat experimental value
`erc-server-delayed-check-reconnect'.
(erc--server-connect-function): Add variable for process-dialing
monitor, a function.
(erc--server-propagate-failed-connection): Add function to serve as
default monitor to run on process creation and maybe execute failure
handlers.
(erc-server-connect): Run `erc--server-connect-function' for async
processes one second after creation.
(erc--server-reconnect-timeout, erc--server-reconnect-timeout-check,
erc--server-reconnect-timeout-scale-function,
erc--server-reconnect-timeout-double): Add supporting variables and
functions for `erc-server-delayed-check-reconnect'.
(erc-server-delayed-check-reconnect): Add possible alternate value for
option `erc-server-reconnect-function' that only attempts to reconnect
after hearing back from the server.
(erc-schedule-reconnect): Ensure previous `erc-server-process' is
deleted.
* test/lisp/erc/erc-scenarios-base-auto-recon.el: New file.
* test/lisp/erc/resources/base/reconnect/just-eof.eld: New file.
* test/lisp/erc/resources/base/reconnect/just-ping.eld: New file.
* test/lisp/erc/resources/base/reconnect/ping-pong.eld: New file.
* test/lisp/erc/resources/base/reconnect/unexpected-disconnect.eld:
New file.
* test/lisp/erc/resources/erc-scenarios-common.el
(erc-scenarios-common--make-bindings): Shadow
`timer-list'. (Bug#62044.)
* lisp/erc/erc-backend.el (erc-server-402, erc-server-402-functions):
Add new response handler and hook.
* lisp/erc/erc.el (erc-cmd-MOTD): New function to shield erc-network
from handling post-connection MOTD replies. Thanks to Emanuel Berg
for reporting this (bug#62151).
(erc-message-english-s402): Define new ERR_NOSUCHSERVER message
template.
* test/lisp/erc/erc-scenarios-base-misc-regressions.el: New file.
* test/lisp/erc/resources/base/commands/motd.eld: New file.
* lisp/erc/erc-dcc.el (erc-cmd-DCC): Tokenize raw input line but also
accommodate legacy invocation.
(pcomplete/erc-mode/DCC): Quote file names when suggesting. Account
for double-hyphen "end-of-options"-like separator.
(erc-dcc-do-GET-command): Simplify signature, subsuming NICK in
variadic args, now ARGS instead of FILE, which changes the arity
from (2 . many) to (1 . many). Explain usage in doc string. Honor an
optional separator, "--", if present. (Bug#62444.)
* test/lisp/erc/erc-dcc-tests.el (erc-dcc-do-GET-command): Call new
parameterized helper with various flag/file combinations.
(erc-dcc-tests--erc-dcc-do-GET-command): New fixture function.
(pcomplete/erc-mode/DCC--get-quoted,
pcomplete/erc-mode/DCC--get-sep): New tests.
* lisp/erc/erc-compat.el (erc-compat--28-split-string-shell-command,
erc-compat--split-string-shell-command): New functions introduced in
Emacs 28 for splitting pcomplete input.
* lisp/erc/erc-dcc.el (erc-cmd-DCC): Elect to tokenize line specially.
(erc-dcc--cmd-help): Add help handler. (Bug#62444.)
* lisp/erc/erc.el (erc-cmd-HELP): Change signature by adding &rest
parameter. Look for symbol property `erc--cmd-help' and, if found,
assume it's a function and call it with &rest args after attempting to
autoload the primary command symbol. (Bug#62444.)
* lisp/erc/erc.el: Update main Version header and bump required Compat
to latest release in Package-Requires header. Also update entry in
`customize-package-emacs-version-alist', mapping ERC 5.6 to Emacs
30.1.
(erc-version): Move to 5.6-git.
The documentation of each signature was rarely rendered because of
obsolete logic that skipped MarkupContent objects.
The new function follows the principle that echo are gets as little as
possible, while the *eldoc* buffer gets as much as possible (except,
for the individual parameter documentation, as I couldn't find a
single server that uses it).
Tested with clangd, pylsp, jdtls, gopls, rust-analyzer, zls.
* lisp/progmodes/eglot.el (eglot--sig-info): Simplify.
Move the warning about unused return values from calls to
side-effect-free functions from the source-level optimiser to the code
generator, where it can be unified with the special-purpose warning
about unused values from `mapcar`. This change also cures spurious
duplicate warnings about the same code, makes the warnings amenable to
suppression through `with-suppressed-warnings`, and now warns about
some unused values that weren't caught before.
* lisp/emacs-lisp/byte-opt.el (byte-optimize-form-code-walker):
Move warning away from here.
* lisp/emacs-lisp/byte-run.el (with-suppressed-warnings):
* lisp/emacs-lisp/bytecomp.el (byte-compile-warnings):
Doc string updates.
(byte-compile-form): Put the new warnings here.
(byte-compile-normal-call): Move mapcar warning away from here.
* lisp/emacs-lisp/bytecomp.el (byte-compile-ignore):
Compile args to `ignore` for value to avoid unused-value warnings, and
then discard the generated values immediately thereafter. Mostly this
does not affect the generated code but in rare cases it might result
in slightly worse code.
* test/lisp/emacs-lisp/bytecomp-tests.el
(bytecomp-test--with-suppressed-warnings): Adapt test.
