* etc/ERC-NEWS: Let users know that `keep-place-indicator' is a wholly
separate module from `keep-place'.
* lisp/erc/erc-goodies.el (erc-keep-place-indicator-setup): Perform
some housekeeping on `erc-keep-place-mode'.
(erc-keep-place-indicator-mode, erc-keep-place-indicator-enable,
erc-keep-place-indicator-disable): Take precautions to work around the
activation state of global module `keep-place', but no longer depend
on it.
(erc--keep-place-indicator-on-global-module): New function to ensure
`erc-keep-place' runs exactly once on `erc-insert-pre-hook',
regardless of whether module `keep-place' is active.
* test/lisp/erc/erc-goodies-tests.el
(erc-goodies-tests--assert-kp-indicator-on,
erc-goodies-tests--assert-kp-indicator-off,
erc-goodies-tests--kp-indicator-populate,
erc-goodies-tests--keep-place-indicator): New helper functions.
(erc-keep-place-indicator-mode,
erc-keep-place-indicator-mode--no-global): Factor out some common
logic and rename former to latter.
(erc-keep-place-indicator-mode--global): New test. (Bug#59943)
* lisp/erc/erc-goodies.el (erc-scroll-to-bottom): Only `recenter' when
the selected window's buffer is current. Previously, the module
`scrolltobottom' signaled an "Error in `post-command-hook'" when a
user clicked a channel indicator in the mode line from a window
showing another ERC buffer.
* lisp/erc/erc-track.el (erc-track--switch-fallback-blockers): New
internal variable used by `erc-track--switch-buffer' in deciding
whether to set `erc-track-last-non-erc-buffer' to the current buffer.
(erc-track--switch-buffer): Consult list of `buffer-match-p'
conditions in `erc-track--switch-fallback-blockers' to decide whether
to set `erc-track-last-non-erc-buffer' to the current buffer.
(Bug#63595)
* lisp/erc/erc-goodies.el (erc-scrolltobottom-enable,
erc-scrolltobottom-mode): Prefer `erc-buffer-do' to
`erc-buffer-filter'.
(erc-move-to-prompt-mode, erc-move-to-prompt-enable): Prefer
`erc-buffer-do' to `erc-buffer-filter'.
* lisp/erc/erc-imenu.el (erc-imenu-mode, erc-imenu-enable): Prefer
`erc-buffer-do' to `erc-buffer-filter'.
* lisp/erc/erc-match.el (erc-match-enable, erc-match-mode): Prefer
`erc-buffer-do' to `erc-buffer-filter'.
* lisp/erc/erc-stamp.el (erc-stamp-mode, erc-stamp-enable): Prefer
`erc-buffer-do' to `erc-buffer-filter'.
* lisp/erc/erc.el (erc-buffer-filter): Improve doc string.
(erc-buffer-do): Add alias for new code to prefer when calling
`erc-buffer-filter' for effect. Do this because continually having to
refer back to the doc strings and implementations of the latter as
well as `erc-buffer-p', `erc-buffer-list', and co. is unproductive.
(erc-buffer-list): Use `always' as fallback predicate.
* lisp/erc/erc-goodies.el (erc-scrolltobottom-mode,
erc-scrolltobottom-enable, erc-move-to-prompt-mode,
erc-move-to-prompt-enable): Guard setup procedure behind
`erc--updating-modules-p'.
* lisp/erc/erc-imenu.el (erc-imenu-mode, erc-imenu-enable,
erc-imenu-disable): Don't run setup when `erc--updating-modules-p' is
non-nil. Also, don't restrict teardown to buffers of the same
process.
* lisp/erc/erc-match.el (erc-match-mode, erc-match-enable): Run
major-mode hook member immediately outside of `erc-update-modules' in
`erc-open'.
* lisp/erc/erc-spelling.el (erc-spelling-mode, erc-spelling-enable):
Only conditionally run setup immediately.
* lisp/erc/erc-stamp.el (erc-stamp-mode, erc-stamp-enable,
erc-stamp-disable): Run setup hook immediately. Don't forget to
kill local vars in all ERC buffers during teardown.
* lisp/erc/erc.el (erc--updating-modules-p): New variable that global
modules can use to provide their `erc-mode-hook'-deferred code on
demand while shielding it from running during early ERC buffer
initialization.
(erc-open): Make `erc--updating-modules-p' non-nil while activating
global modules. (Bug#60936)
* lisp/erc/erc-common.el (erc--input-split): Suppress warning for
obsolete variable `erc-send-this' in init form.
* lisp/erc/erc-goodies.el (erc--keep-place-indicator-setup): Use macro
`erc--restore-initialize-priors' to preserve last session's indicator
position, if any.
(erc-keep-place-indicator-mode, erc-keep-place-indicator-enable): Use
convenience function to show missing-dependency notice.
* lisp/erc/erc-sasl.el (erc-sasl-auth-source-password-as-host): Merge
redundant `when' forms for clarity.
(erc-sasl--init): Remove unused function.
(erc-sasl-mode, erc-sasl-enable): Use helper to restore
`erc-sasl--options', essentially inlining the body of the now defunct
`erc-sasl--init'.
* lisp/erc/erc.el (erc--restore-initialize-priors): New macro to help
local modules and mode hooks prefer existing state over initializing
anew.
(erc--warn-once-before-connect): Add helper function to display
an "error notice" just after module setup.
(erc-accidental-paste-threshold-seconds) Improve doc string.
* test/lisp/erc/erc-goodies-tests.el
(erc-controls-highlight--examples, erc-controls-highlight--inverse,
erc-controls-highlight--motd, erc-keep-place-indicator-mode): Remove
feature check. For the latter, also start fake process and shadow
`erc-connect-pre-hook'.
* test/lisp/erc/erc-tests.el (erc--restore-initialize-priors): New
test. Also see test/lisp/erc/erc-scenarios-base-local-modules.el for
a more realistic exercising of this functionality. (Bug#60936)
* etc/ERC-NEWS: Mention revised role of `erc-pre-send-functions'
relative to line splitting.
* lisp/erc/erc-common.el (erc-input): Add new slot `refoldp' to allow
`erc-pre-send-functions' members to indicate that splitting should
occur a second time after all members have had their say.
(erc--input-split): Specify some defaults for overridden slots and
explicitly declare some types for good measure.
* lisp/erc/erc-goodies.el (erc-noncommands-mode,
erc-noncommands-enable, erc-noncommands-disable): Replace
`erc-pre-send-functions' with `erc--input-review-functions'.
* lisp/erc/erc-ring.el (erc-ring-enable, erc-ring-disable,
erc-ring-mode): Subscribe to `erc--input-review-functions' instead of
`erc-pre-send-functions' for `erc--add-to-input-ring'.
* lisp/erc/erc.el (erc-pre-send-functions): Note some nuances
regarding line splitting in doc string and note that a new slot is
available.
(erc--pre-send-split-functions, erc--input-review-functions): Rename
former to latter, while also obsoleting. Remove large comment. Add
new default member `erc--run-input-validation-checks'.
(erc-send-modify-hook): Replace the obsolete `erc-send-pre-hook' and
`erc-send-this' with `erc-pre-send-functions' in doc string.
(erc--check-prompt-input-for-excess-lines): Don't trim trailing
blanks. Rework to also report overages in characters as well as
lines.
(erc--run-input-validation-hooks): New function to adapt an
`erc--input-split' object to `erc--check-prompt-input-functions'.
(erc-send-current-line): Run `erc--input-review-functions' in place of
the validation hooks they've subsumed. Call `erc--send-input-lines'
instead of the now retired but not deprecated `erc-send-input'.
(erc--run-send-hooks, erc--send-input-lines): New functions that
together form an alternate version of `erc-send-input'. They operate
on input linewise but make accommodations for older interfaces.
* test/lisp/erc/erc-tests.el (erc-ring-previous-command): Replace
`erc-pre-send-functions' with `erc--input-review-functions'.
(erc-tests--with-process-input-spy): Shadow
`erc--input-review-functions'.
(erc-check-prompt-input-for-excess-lines): Don't expect trailing
blanks to be trimmed.
(erc--run-send-hooks): New test. (Bug#62947)
* 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.)
* 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.)
* doc/misc/erc.texi: Mention local modules in Modules chapter.
* etc/ERC-NEWS: Mention changes to `erc-update-modules'.
* lisp/erc/erc.el (erc-migrate-modules): Add some missing mappings.
(erc-modules): When a user removes a module, disable it and kill its
local variable in all ERC buffers.
(erc-update-modules): Move body of `erc-update-modules' to new
internal function.
(erc--update-modules): Add new function, a renamed and slightly
modified version of `erc-update-modules'. Specifically, change return
value from nil to a list of minor-mode commands for local modules.
Use `custom-variable-p' to detect flavor.
(erc--merge-local-modes): Add helper for finding local modules
already active as minor modes in an ERC buffer.
(erc-open): Replace `erc-update-modules' with `erc--update-modules'.
Defer enabling of local modules via `erc--update-modules' until after
buffer is initialized with other local vars. Also defer major-mode
hooks so they can detect things like whether the buffer is a server or
target buffer. Also ensure local module setup code can detect when
`erc-open' was called with a non-nil `erc--server-reconnecting'.
* lisp/erc/erc-common.el (erc--module-name-migrations,
erc--features-to-modules, erc--modules-to-features): Add alists of
old-to-new module names to support module-name migrations.
(erc--assemble-toggle): Add new helper for constructing mode toggles,
like `erc-sasl-enable'.
(define-erc-modules): Defer to `erc--assemble-toggle' to create toggle
commands.
(erc--normalize-module-symbol): Add helper for `erc-migrate-modules'.
* lisp/erc/erc-goodies.el: Require cl-lib.
* test/lisp/erc/erc-tests.el (erc-migrate-modules,
erc--update-modules): Add rudimentary unit tests asserting correct
module-name mappings.
(erc--merge-local-modes): Add test for helper.
(define-erc-module--global, define-erc-module--local): Add tests
asserting module-creation macro. (Bug#57955.)
* lisp/erc/erc-dcc.el (erc-dcc-member): Remove XEmacs compat code.
* lisp/erc/erc-goodies.el (erc-move-to-prompt-setup): Doc fix;
remove spurious reference to XEmacs; this is needed also for
Emacs.
Also remove various redundant `:group` arguments.
* lisp/erc/erc-backend.el (define-erc-response-handler): Move `declare`
after the docstring.
* lisp/erc/erc-capab.el: Use lexical-binding.
(erc-capab-identify-activate): Simplify with `member`.
* lisp/erc/erc-dcc.el (erc-dcc): Move before erc-dcc-mode definition,
which refers to it.
(erc-dcc-chat-accept): Remove unused vars `nick` and `buffer`.
* lisp/erc/erc-imenu.el: Use lexical-binding.
(erc-create-imenu-index): Remove unused var `prev-pos`.
* lisp/erc/erc-match.el: Use lexical-binding.
(erc-match-message): Remove unused var `old-pt`.
(erc-match-message): Strength-reduce `eval` to `symbol-value`.
* lisp/erc/erc-page.el: Use lexical-binding.
(erc-page): Move Custom group before `erg-page-mode` which refers to it.
* lisp/erc/erc-replace.el: Use lexical-binding.
(erc-replace-insert): Use `functionp`.
* lisp/erc/erc-status-sidebar.el: Use lexical-binding.
(erc-status-sidebar-open): Remove unused var `sidebar-window`.
* lisp/erc/erc.el: Fix header to use the customary 3 semi-colons.
(erc-fill-column): Declare variable.
* lisp/erc/erc-autoaway.el: Use lexical-binding.
* lisp/erc/erc-ezbounce.el: Use lexical-binding.
* lisp/erc/erc-fill.el: Use lexical-binding.
* lisp/erc/erc-goodies.el: Use lexical-binding.
* lisp/erc/erc-ibuffer.el: Use lexical-binding.
* lisp/erc/erc-identd.el: Use lexical-binding.
* lisp/erc/erc-join.el: Use lexical-binding.
* lisp/erc/erc-lang.el: Use lexical-binding.
* lisp/erc/erc-log.el: Use lexical-binding.
* lisp/erc/erc-menu.el: Use lexical-binding.
* lisp/erc/erc-netsplit.el: Use lexical-binding.
* lisp/erc/erc-networks.el: Use lexical-binding.
* lisp/erc/erc-pcomplete.el: Use lexical-binding.
* lisp/erc/erc-ring.el: Use lexical-binding.
* lisp/erc/erc-speedbar.el: Use lexical-binding.
* lisp/erc/erc-spelling.el: Use lexical-binding.
* lisp/erc/erc-truncate.el: Use lexical-binding.
* lisp/erc/erc-xdcc.el: Use lexical-binding.
* lisp/erc/erc-goodies.el (erc-italic-face): New face for italic text.
(erc-controls-interpret), (erc-controls-highlight): Add `italicp'.
(erc-controls-remove-regexp),
(erc-controls-highlight-regexp): Handle C-] for italic.
(erc-controls-propertize): Add `italicp' argument and use it to
conditionally propertize text with the new `erc-italic-face'.
* etc/NEWS: Announce italic text support.
* lisp/erc/erc-goodies.el (erc-possibly-scroll-to-bottom): New
function.
(scrolltobottom): Add to erc-insert-done-hook.
* lisp/erc/erc.el (erc-insert-done-hook): New hook (bug#11697).
(erc-display-line-1): Use it.
* lisp/erc/erc-ring.el (erc-add-to-input-ring):
* lisp/erc/erc-goodies.el (erc-send-distinguish-noncommands): Pass
in a erc-input structure instead of a simple string.
* lisp/erc/erc.el (erc-pre-send-functions): Document the new
argument to the filter functions.
(erc-send-input): Use the new structure to allow the filter
functions to alter all three things: The string, whether to insert
the string, and whether to send the string.
* lisp/erc/erc-goodies.el (noncommands): Use
erc-pre-send-functions instead of the hook.
(erc-send-distinguish-noncommands): Adjust function to new interface.
* lisp/erc/erc-ring.el (ring): Ditto.
(erc-add-to-input-ring): Ditto.
* lisp/erc/erc.el (erc-send-this): Really make obsolete.
(erc-pre-send-functions): Change to a list of functions to allow
erc-goodies and erc-ring to work as before.
Restore lines saying "Maintainer: emacs-devel@gnu.org" when there is
no special maintainer for a file. Although this wasn't documented
it was common practice and removing the lines didn't have consensus.
* lisp/erc/erc-goodies.el (erc-keep-place): Allow erc
keep-place to continue working with
switch-to-buffer-preserve-window-point set to t, the new default.
Copyright-paperwork-exempt: yes
Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.
