This file is about changes in ERC, the powerful, modular, and
extensible IRC (Internet Relay Chat) client distributed with
GNU Emacs since Emacs version 22.1.
* Changes in ERC 5.6
** Module 'keep-place' has a more decorative cousin.
Remember your place in ERC buffers a bit more easily with the help of
a configurable, visible indicator. Optionally sync the indicator to
any progress made while you haven't yet caught up to the live stream.
See options 'erc-keep-place-indicator-style' and friends, and try M-x
keep-place-indicator-mode to see it in action.
** Module 'fill' offers an adaptive style based on 'visual-line-mode'.
This style dynamically wraps messages to a window's width while
mimicking the "hanging indent" look of 'erc-fill-static'. It also
provides some movement and editing commands to optionally tame the
less familiar aspects of 'visual-line' behavior. An interactive
helper called 'erc-fill-wrap-nudge' makes easy work of adjusting the
overhang on the fly. Set 'erc-fill-function' to 'erc-fill-wrap' to
get started.
** A module for nickname highlighting has joined ERC.
Automatic nickname coloring has come to ERC core. Users familiar with
'erc-hl-nicks', from which this module directly descends, will already
be familiar with its suite of handy options. By default, each
nickname in an ERC session receives a unique face with a unique (or
uniformly dealt) foreground color. Add 'nicks' to 'erc-modules' to
get started.
** A unified interactive entry point.
New users are often dismayed to discover that M-x ERC doesn't connect
to its default network, Libera.Chat, over TLS. Though perhaps a
decade overdue, this is no longer the case. Other UX improvements in
this area aim to make the process of connecting interactively slightly
more streamlined and less repetitive, even for veteran users.
Allow custom display-buffer actions in ERC * doc/misc/erc.texi: Add new section under "Integrations" chapter describing `display-buffer' Custom function choice for ERC's many buffer-display options. * etc/ERC-NEWS: Mention new function variant for all buffer-display options. * lisp/erc/erc-backend.el: Add forward declaration for `erc--called-as-input-p' and `erc--display-context'. (erc--server-reconnect-display-timer, erc--server-last-reconnect-display-reset): Use new name for option `erc-reconnect-display', now `erc-auto-reconnect-display'. (erc--server-determine-join-display-context): New generic function to determine value of `erc--display-context' during JOINs. (erc-server-JOIN, erc-server-PRIVMSG): Set `erc--display-context' to a symbol for the handler's IRC command, like `JOIN', for the benefit of custom `display-buffer'-like functions running in `erc-setup-buffer'. (erc-server-471, erc-server-471-functions, erc-server-473, erc-server-473-functions): New handlers for JOIN rejections. Also remove 471 and 473 from comment at bottom of file. (erc-server-475): Bind `erc--called-as-input-p' so that `erc-cmd-JOIN' sets `erc-interactive-display' context. * lisp/erc/erc-join.el (erc-autojoin-mode, erc-autojoin-enable, erc-autojoin-disable): Kill local variable `erc-join--requested-channels'. Add and remove `erc-join--remove-requested-channels' to/from various server-handler hooks for JOIN rejection numerics. (erc-join--requested-channels): New local variable to remember channels we've attempted to JOIN this session that haven't yet been confirmed by the server. (erc-join--remove-requested-channel): New JOIN rejection handler to stop tracking channel in `erc-join--requested-channels'. (erc--server-determine-join-display-context): module-specific implementation of generic function for `erc-autojoin-mode'. (erc-autojoin--join): Remember channels slated for JOIN'ing. * lisp/erc/erc.el (erc--buffer-display-choices): New helper constant for defining common `:type' for all buffer-display options. (erc-buffer-display, erc-interactive-display, erc-auto-reconnect-display, erc-receive-query-display): Use helper `erc--buffer-display-choices' for defining `:type', which includes a new choice for a `display-buffer'-like function. (erc-reconnect-display, erc-auto-reconnect-display): Alias former to latter, now the preferred name. (erc-reconnect-timeout, erc-auto-reconnect-timeout): Change name from former to latter. This option is new in ERC 5.6. (erc-reconnect-display-server-buffers): New option. (erc-buffer-do): Revise doc string. (erc--display-context): New variable, an alist of "context tokens" to be forwarded as the "action alist" to `erc-buffer-display' functions. (erc-skip-displaying-selected-window-buffer): New variable, deprecated at birth, to act as an escape hatch for folks who don't want to skip the displaying of buffers already showing in the selected window. (erc--display-buffer-overriding-action): Local variable allowing modules to influence the displaying of new ERC buffers independently of user options. (erc-setup-buffer): Do nothing when the selected window already shows current buffer unless user has provided a custom display function. Accommodate new Custom choice function values, like `display-buffer' and `pop-to-buffer'. (erc-open): Run `erc-setup-buffer' when option `erc-reconnect-display-server-buffers' is non-nil, even for existing server buffers. Bind `display-buffer-overriding-action' to the value of `erc--display-buffer-overriding-action' around calls to `erc-setup-buffer'. (erc-select-read-args): Add `erc--display-context' to environment. (erc, erc-tls): Bind `erc--display-context' around calls to `erc-select-read-args' and main body. (erc-cmd-JOIN, erc-cmd-QUERY, erc--cmd-reconnect, erc-handle-irc-url): Add item for `erc-interactive-display' to `erc--display-context'. (erc-connection-established): Update name of `erc-reconnect-display-timeout' to `erc-auto-reconnect-display-timeout'. (erc-message-english-s471, erc-message-english-s473): New variables, format templates for JOIN rejection messages. * test/lisp/erc/erc-scenarios-base-buffer-display.el (erc-scenarios-base-buffer-display--defwin-recbury-intbuf, erc-scenarios-base-buffer-display--defwino-recbury-intbuf, erc-scenarios-base-buffer-display--count-reset-timeout): Use preferred name `erc-auto-reconnect-display' for `erc-reconnect-display'. * test/lisp/erc/erc-scenarios-join-display-context.el: New file. * test/lisp/erc/erc-tests.el (erc--initialize-markers): Fix unrealistic call to `erc-open'. (erc-setup-buffer--custom-action): New test. (erc-select-read-args, erc-tls, erc--interactive, erc-server-select): Expect new environment binding for `erc--display-context'. * test/lisp/erc/resources/join/buffer-display/mode-context.eld: New file.

** Revised buffer-display handling.
A point of friction for new users and one only just introduced with
ERC 5.5 has been the lack of visual feedback when first connecting via
Extend erc-interactive-display to cover /JOINs * lisp/erc/erc.el (erc-display): Mention that buffer-related display options live in the customization group `erc-buffers'. (erc-buffer-display, erc-join-buffer): Swap alias and aliased so that the favored name, `erc-buffer-display', appears in the definition and in the Customize menu. Also note related buffer-display options in the doc string. (erc-query-display, erc-interactive-display): Make the former an alias of the latter, new in ERC 5.6, because their roles were functionally redundant and thus confusing. Inherit the default value from `erc-query-display' because users are more familiar with the pop-up window behavior than a single-window replacement. (erc-reconnect-display): Use preferred name for cross-referencing fallback option `erc-buffer-display' in doc string, and explain how /reconnect handling differs. (erc--setup-buffer-hook): Add new internal hook for modules that operate on windows and frames, such as erc-speedbar and erc-status-sidebar. (erc-open): Run `erc--setup-buffer-hook' after `erc-setup-buffer' so hook members know their code isn't tied to `erc-setup-buffer' itself, which may be used in other contexts, but rather to a new ERC buffer on which some display-related action has just been performed. (erc--called-as-input-p): New variable for "slash" commands, like `erc-cmd-FOO', to detect whether they're being called "interactively" as a result of input given at ERC's prompt. (erc-process-input-line): Bind `erc--called-as-input-p' when running slash commands. (erc-cmd-JOIN): When called interactively, schedule a callback to wrap the response handler and control how new buffers are thus displayed. (erc-cmd-QUERY): Use preferred alias for `erc-query-display'. * test/lisp/erc/erc-scenarios-base-buffer-display.el: (erc-scenarios-base-buffer-display--interactive-default): New test. * test/lisp/erc/erc-tests.el (erc-process-input-line, erc-select-read-args, erc-tls, erc--interactive): Change expected default value of `erc-interactive-display' from `buffer' to `window'.

M-x erc or when issuing a "/JOIN" command at the prompt. As explained
below, in the news for 5.5, the discovery of a security issue led to
most new ERC buffers being "buried" on creation. On further
reflection, this was judged to have been an overcorrection in the case
of interactive invocations, hence the borrowing of an old option,
'erc-query-display', and the bestowing of a new alias,
'erc-interactive-display', which better describes its expanded role as
a more general buffer-display knob for interactive commands ("/QUERY"
still among them).
Accompanying this addition are "display"-suffixed aliases for related
options 'erc-join-buffer' and 'erc-auto-query', which users have
reported as being difficult to discover and remember. When the latter
option (now known as 'erc-receive-query-display') is nil, ERC uses
'erc-join-buffer' in its place, much like it does for
'erc-interactive-display'. The old nil behavior can still be gotten
Allow custom display-buffer actions in ERC * doc/misc/erc.texi: Add new section under "Integrations" chapter describing `display-buffer' Custom function choice for ERC's many buffer-display options. * etc/ERC-NEWS: Mention new function variant for all buffer-display options. * lisp/erc/erc-backend.el: Add forward declaration for `erc--called-as-input-p' and `erc--display-context'. (erc--server-reconnect-display-timer, erc--server-last-reconnect-display-reset): Use new name for option `erc-reconnect-display', now `erc-auto-reconnect-display'. (erc--server-determine-join-display-context): New generic function to determine value of `erc--display-context' during JOINs. (erc-server-JOIN, erc-server-PRIVMSG): Set `erc--display-context' to a symbol for the handler's IRC command, like `JOIN', for the benefit of custom `display-buffer'-like functions running in `erc-setup-buffer'. (erc-server-471, erc-server-471-functions, erc-server-473, erc-server-473-functions): New handlers for JOIN rejections. Also remove 471 and 473 from comment at bottom of file. (erc-server-475): Bind `erc--called-as-input-p' so that `erc-cmd-JOIN' sets `erc-interactive-display' context. * lisp/erc/erc-join.el (erc-autojoin-mode, erc-autojoin-enable, erc-autojoin-disable): Kill local variable `erc-join--requested-channels'. Add and remove `erc-join--remove-requested-channels' to/from various server-handler hooks for JOIN rejection numerics. (erc-join--requested-channels): New local variable to remember channels we've attempted to JOIN this session that haven't yet been confirmed by the server. (erc-join--remove-requested-channel): New JOIN rejection handler to stop tracking channel in `erc-join--requested-channels'. (erc--server-determine-join-display-context): module-specific implementation of generic function for `erc-autojoin-mode'. (erc-autojoin--join): Remember channels slated for JOIN'ing. * lisp/erc/erc.el (erc--buffer-display-choices): New helper constant for defining common `:type' for all buffer-display options. (erc-buffer-display, erc-interactive-display, erc-auto-reconnect-display, erc-receive-query-display): Use helper `erc--buffer-display-choices' for defining `:type', which includes a new choice for a `display-buffer'-like function. (erc-reconnect-display, erc-auto-reconnect-display): Alias former to latter, now the preferred name. (erc-reconnect-timeout, erc-auto-reconnect-timeout): Change name from former to latter. This option is new in ERC 5.6. (erc-reconnect-display-server-buffers): New option. (erc-buffer-do): Revise doc string. (erc--display-context): New variable, an alist of "context tokens" to be forwarded as the "action alist" to `erc-buffer-display' functions. (erc-skip-displaying-selected-window-buffer): New variable, deprecated at birth, to act as an escape hatch for folks who don't want to skip the displaying of buffers already showing in the selected window. (erc--display-buffer-overriding-action): Local variable allowing modules to influence the displaying of new ERC buffers independently of user options. (erc-setup-buffer): Do nothing when the selected window already shows current buffer unless user has provided a custom display function. Accommodate new Custom choice function values, like `display-buffer' and `pop-to-buffer'. (erc-open): Run `erc-setup-buffer' when option `erc-reconnect-display-server-buffers' is non-nil, even for existing server buffers.

via the new compatibility flag 'erc-receive-query-display-defer'. The
relatively new option 'erc-reconnect-display' has likewise been
renamed, this time for clarity, to 'erc-auto-reconnect-display'.
This release also introduces a few subtleties affecting the display of
new or reassociated buffers. One involves buffers that already occupy
the selected window. ERC now treats these as deserving of an implicit
'bury'. An escape hatch for this and most other baked-in behaviors is
now available in the form of a new type variant recognized by all such
options. That is, users can now specify their own function to
exercise full control over nearly all buffer-display related
decisions. See the newly expanded doc strings of 'erc-buffer-display'
and friends, as well as Info node '(erc) display-buffer', for details.
** Setting a module's mode variable via Customize earns a warning.
Trying and failing to activate a module via its minor mode's Custom
widget has been an age-old annoyance for new users. Previously
ineffective, this method now actually works, but it also admonishes
users to edit the 'erc-modules' widget instead.
** ERC's status-sidebar has gained an accompanying module.
Users can now add 'bufbar' to 'erc-modules' to achieve the same effect
as toggling 'erc-status-sidebar-open' manually at the start of an IRC
session. The module has also been outfitted to show channels and
queries under their servers by default. To avoid confusion, the major
mode for the actual sidebar buffer itself, 'erc-status-sidebar-mode',
is no longer available interactively.
** A new spin on a classic integration in erc-speedbar.
Add 'nickbar' to 'erc-modules' to spawn a dynamically updating side
window listing all the users in any target buffer. It's powered by
the same speedbar.el integration you've always known, except this
one's optionally accessible from the keyboard, just like any other
side window. Hit '<RET>' over a nick to spawn a "/QUERY" or a
"Lastlog" (Occur) session. See 'erc-nickbar-mode' for more.
** The option 'erc-timestamp-use-align-to' is more versatile.
While this option has always offered to right-align stamps via the
'display' text property, it's now more effective at doing so when set
Make erc-fill-wrap work with left-sided stamps * etc/ERC-NEWS: Remove all mention of option `erc-timestamp-align-to' supporting a value of `margin', which has been abandoned. Do mention leading white space before stamps now having stamp-related properties. * lisp/erc/erc-backend.el (erc--reveal-prompt, erc--conceal-prompt): New generic functions with default implementations factored out from `erc--unhide-prompt' and `erc--hide-prompt'. (erc--prompt-hidden-p): New internal predicate function. (erc--unhide-prompt): Defer to `erc--reveal-prompt', and set `erc-prompt' text property to t. (erc--hide-prompt): Defer to `erc--conceal-prompt', and set `erc-prompt' text property to `hidden'. * lisp/erc/erc-compat.el (erc-compat--29-browse-url-irc): Don't use `function-equal'. * lisp/erc/erc-fill.el (erc-fill-wrap-margin-width, erc-fill-wrap-margin-side): New options to control side and initial width of `fill-wrap' margin. (erc-fill--wrap-beginning-of-line): Fix bug involving non-string valued `display' props. (erc-fill-wrap-toggle-truncate-lines): New command to re-enable `visual-line-mode' when toggling off `truncate-lines'. (erc-fill-wrap-mode-map): Remap `toggle-truncate-lines' to `erc-fill-wrap-toggle-truncate-lines'. (erc-fill-wrap-mode, erc-fill-wrap-enable, erc-fill-wrap-disable): Update doc string, persist a few local vars, and conditionally set `erc-stamp--margin-left-p'. When deactivating, disable `visual-line-mode' first. (erc-fill--wrap-continued-message-p): Use `erc-speaker' instead of heuristics when comparing nicks between consecutive messages. (erc-fill-wrap-nudge): Update doc string and account for left-sided stamps. (erc-timestamp-offset): Add comment regarding conditional guard based on function-valued option. * lisp/erc/erc-stamp.el (erc-timestamp-use-align-to): Remove value variant `margin', which was originally intended to be new in ERC 5.6. This functionality was all but useless without the internal minor mode `erc-stamp--display-margin-mode' active. (erc-stamp-right-margin-width): Remove unused option new in 5.6. (erc-stamp--display-margin-force): Remove unused function. (erc-stamp--margin-width, erc-stamp--margin-left-p): New internal variables. (erc-stamp--init-margins-on-connect): New function for initializing mode-managed margin after connecting. (erc-stamp--adjust-right-margin, erc-stamp--adjust-margin): Rename function to latter and accommodate left-hand stamps. (erc-stamp--inherited-props): Move definition higher up in same file. (erc-stamp--display-margin-mode): Update function name, and adjust setup and teardown to accommodate left-handed stamps. Don't add advice around `erc-insert-timestamp-function'. (erc-stamp--last-prompt, erc-stamp--display-prompt-in-left-margin): New function and helper var to convert a normal inserted prompt so that it appears in the left margin. (erc-stamp--refresh-left-margin-prompt): Helper for other modules to quickly refresh prompt outside of insert hooks. (erc--reveal-prompt, erc--conceal-prompt): New implementations for when `erc-stamp--display-margin-mode' is active. (erc-insert-timestamp-left): Convert to generic function and provide implementation for `erc-stamp--display-margin-mode'. (erc-stamp--omit-properties-on-folded-lines): New variable, an escape hatch for propertizing white space before right-side stamps folded over onto another line. (erc-insert-timestamp-right): Don't expect `erc-timestamp-align-to' to ever be the symbol `margin'. Move handling for that case to one contingent on the internal minor mode `erc-stamp--display-margin-mode' being active. Add text properties preceding stamps that occupy a line by their lonesome. See related news entry for rationale. This is arguably a breaking change. * lisp/erc/erc.el (erc--refresh-prompt-hook): New hook variable for modules to adjust prompt properties whenever it's refreshed. (erc--refresh-prompt): Fix bug in which user-defined prompt functions failed to hide when quitting in server buffers. Run new hook `erc--refresh-prompt-hook'. (erc-display-prompt): Add comment noting that the text property `erc-prompt' now actually matters: it's t while a session is running and `hidden' when disconnected. * test/lisp/erc/erc-fill-tests.el (erc-fill--left-hand-stamps): New test. * test/lisp/erc/erc-stamp-tests.el (erc-stamp-tests--use-align-to--nil, erc-stamp-tests--use-align-to--t): New functions forged from old test bodies to allow optionally asserting pre-5.6 behavior regarding leading white space on right-hand stamps that exist on their own line. (erc-timestamp-use-align-to--nil, erc-timestamp-use-align-to--t): Parameterize with compatibility flag. (erc-timestamp-use-align-to--margin, erc-stamp--display-margin-mode--right): Rename test to latter. * test/lisp/erc/erc-tests.el (erc-hide-prompt): Add some assertions for new possible value of `erc-prompt' text property. * test/lisp/erc/resources/fill/snapshots/stamps-left-01.eld: New test data file. (Bug#60936)

to a number indicating an offset from the right edge. Users of the
'log' module may want to customize 'erc-log-filter-function' to
'erc-stamp-prefix-log-filter' to avoid ragged right-hand stamps
appearing in their saved logs.
** Awkward entry point 'erc-server-select' improved but deprecated.
The alternate entry point 'erc-server-select' has mainly served to
confuse users in more recent years because it requires certain
options, like 'erc-nick', to be configured ahead of time, and it
doesn't support TLS. Its main selling point, historically, has been
interactive completion based on the option 'erc-server-alist', which
is a table of networks, servers, and ports. But most of the option's
400-odd entries are sadly defunct or otherwise outdated. And, these
days, most networks promote a well known load-balancing end point over
individual servers anyway. Regardless, the command has now been
improved to prompt for the same slate of parameters sought by
'erc-tls'. Similarly, 'erc-server-alist' entries now support a fifth
member in TLS ports (though this option too has been deprecated). If
you feel these deprecations rash or unwarranted, please file a bug
report and petition the maintainers for a reprieve.
** Smarter reconnect handling for users on the move.
ERC now offers a new, experimental reconnect strategy in the function
'erc-server-delayed-check-reconnect', which tests for underlying
Redo erc-nickname-in-use-functions as a local module * etc/ERC-NEWS: Mention new module `services-regain'. * lisp/erc/erc-backend.el: Rename option. * lisp/erc/erc-services.el (erc-services-regain-alist): Strategies for regaining a lost nickname on reconnect. This option, in addition to the rest of these changes, is a redo of `erc-nickname-in-use-functions' from commit 8c0c9826 "Add hook to regain nickname in ERC", which originally stemmed from bug#62044. (erc-services-retry-nick-on-connect, erc-services-issue-regain, erc-services-issue-ghost-and-retry-nick): New function variants for `erc-services-regain-alist. (erc-services-regain-mode, erc-services-regain-enable, erc-services-regain-disable): New local module to activate nick-regaining behavior. (erc--nickname-in-use-make-request): New method, a services-specific implementation. * lisp/erc/erc.el (erc--nickname-in-use-make-request): New generic function to request alternate nick when first choice is rejected. (erc-nickname-in-use): Call `erc--nickname-in-use-make-request' to request alternate nick. * test/lisp/erc/erc-scenarios-services-misc.el (erc-scenarios-services-misc--reconnect-retry-nick): Adopt renamed version of `erc-scenarios-base-renick-auto-regain'. (erc-scenarios-services-misc--regain-command, erc-scenarios-services-misc--ghost-and-retry-nick): New tests. * test/lisp/erc/resources/services/regain/reconnect-retry-again.eld: New test data file reusing existing blob c0529052 that once lived at resources/base/renick/regain/normal-again.eld. * test/lisp/erc/resources/services/regain/reconnect-retry.eld: New test data file reusing existing blob 9f4df70e5 that once lived at resources/base/renick/regain/normal.eld. * test/lisp/erc/resources/services/regain/taken-ghost.eld: New test data file. * test/lisp/erc/resources/services/regain/taken-regain.eld New test data file.

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

easily determining what right-sided stamps would look like before
insertion, which is knowledge needed for certain UI decisions. The
way ERC has chosen to address this is imperfect and boils down to
asking users who've customized this option to switch to
'erc-timestamp-format' instead. If you're affected by this and feel
that some other solution, like automatic migration, is justified,
please make that known on the bug list.
** 'erc-button-alist' and 'erc-nick-popup-alist' have evolved slightly.
It's no secret that the 'buttons' module treats potential nicknames
specially. This is perhaps most evident in its treatment of the
'nicknames' entry in 'erc-button-alist'. Indeed, to simplify ERC's
move to next-gen "rich UI" extensions, this special treatment is being
canonized. From here on out, this entry will no longer appear in the
option's default value but will instead be applied implicitly so long
as the option 'erc-button-buttonize-nicks' is non-nil, which it is by
default. Relatedly, the option 'erc-nick-popup-alist' now favors
functions, which ERC calls non-interactively, over arbitrary
s-expressions, which ERC will continue to honor. Although the default
lineup remains functionally equivalent, its members have all been
updated accordingly.
** Option 'erc-query-on-unjoined-chan-privmsg' restored and renamed.
This option was accidentally removed from the default client in ERC
5.5 and was thus prevented from influencing PRIVMSG routing. It's now
been restored with a slightly revised role contingent on a few
assumptions explained in its doc string. For clarity, it has been
renamed 'erc-ensure-target-buffer-on-privmsg'.
Skip post-minibuffer restore in erc-scrolltobottom-all * etc/ERC-NEWS: Remove mention of `erc-scrolltobottom-relaxed' in entry for module `scrolltobottom'. * lisp/erc/erc-goodies.el (erc-input-line-position): Fix mention of abandoned option `erc-scrolltobottom-relaxed'. (erc-scrolltobottom-all): Subsume option `erc-scrolltobottom-relaxed' by recognizing a third value state, `relaxed'. A separate option would make more sense if other options also depended on `erc-scrolltobottom-all'. (erc-scrolltobottom-relaxed): Remove redundant option, which was to be new in ERC 5.6. (erc-scrolltobottom-enable, erc-scrolltobottom-mode): Warn if user attempts to enable `erc-scrolltobottom-all' on Emacs 27, which is not supported. (erc--scrolltobottom-relaxed-commands, erc--scrolltobottom-post-force-commands, erc--scrolltobottom-relaxed-skip-commands): Remove unused variables. (erc--scrolltobottom-on-pre-command, erc--scrolltobottom-on-pre-command-relaxed, erc--scrolltobottom-on-post-command-relaxed): Remove unused functions. (erc--scrolltobottom-on-post-command): Remove conditional branch for dealing with a non-nil `erc--scrolltobottom-window-info'. (erc--scrolltobottom-setup): Convert from generic to normal function and remove setup and teardown for unused hooks. Set variable `read-minibuffer-restore-windows' locally when option `erc-scrolltobottom-all' is non-nil. (erc--scrolltobottom-on-pre-insert): Replace reference to subsumed option `erc-scrolltobottom-relaxed' with new value `relaxed' for existing option `erc-scrolltobottom-all'. * test/lisp/erc/erc-scenarios-scrolltobottom-relaxed.el (erc-scenarios-scrolltobottom--relaxed): Replace option `erc-scrolltobottom-relaxed' with new value `relaxed' for `erc-scrolltobottom-all'.

** Module 'scrolltobottom' now optionally more aggressive.
Enabling the experimental option 'erc-scrolltobottom-all' makes ERC
more vigilant about staking down the input area in all ERC windows.
And the option's 'relaxed' variant makes ERC's prompt stationary
wherever it happens to reside instead of forcing it to the bottom of a
window, meaning new input appears above the prompt, scrolling existing
messages upward to compensate.
Consider all windows in erc-scrolltobottom-mode * etc/ERC-NEWS: Add entry for option `erc-scrolltobottom-all', and mention explicit hook-depth intervals reserved by ERC. * lisp/erc/erc-backend.el (erc--hide-prompt): Change hook depth on `pre-command-hook' from 91 to 80. * lisp/erc/erc-goodies.el (erc-input-line-position): Mention secondary role when new option `erc-scroll-to-bottom-relaxed' is non-nil. (erc-scrolltobottom-all): New option that decides whether module `scrolltobottom' affects all windows or just the selected one, as it always has. (erc-scrolltobottom-relaxed): New option to leave the prompt stationary instead of forcing it to the bottom of the window. (erc-scrolltobottom-mode, erc-scrolltobottom-enable, erc-scrolltobottom-disable): Use `erc--scrolltobottom-setup' instead of `erc-add-scroll-to-bottom' for adding and removing local hooks and instead of ranging over buffers when removing them. Also add and remove new hook members when `erc-scrolltobottom-all' is non-nil. (erc--scrolltobottom-relaxed-commands, erc--scrolltobottom-window-info, erc--scrolltobottom-post-force-commands, erc--scrolltobottom-relaxed-skip-commands): New internal variables. (erc--scrolltobottom-on-pre-command erc--scrolltobottom-on-post-command): New functions resembling `erc-possibly-scroll-to-bottom' that try to avoid scrolling repeatedly for no reason. (erc--scrolltobottom-on-pre-command-relaxed, erc--scrolltobottom-on-post-command-relaxed): New commands to help implement `erc-scroll-to-bottom-relaxed'. (erc--scrolltobottom-at-prompt-minibuffer-active): New function to scroll to bottom on window configuration changes when using the minibuffer. (erc--scrolltobottom-all): New function to scroll all windows displaying the current buffer. (erc-add-scroll-to-bottom): Deprecate this function because it is now unused in the default client and trivial to implement otherwise. (erc--scrolltobottom-setup): New generic function to perform teardown as well as setup depending on the state of the module's mode variable. Also add an implementation specifically for `erc-scrolltobottom-all' that locally modifies different sets of hooks depending on `erc-scrolltobottom-relaxed'. (erc--scrolltobottom-on-pre-insert): New generic function that remembers the last `window-start' and maybe the current screen line before inserting a message, in order to restore it afterward. (erc--scrolltobottom-confirm): New function, a replacement for `erc-scroll-to-bottom' that returns non-nil when it's actually recentered the window. For now, used only when `erc-scrolltobottom-all' is enabled. (erc-move-to-prompt-setup): Add `erc-move-to-prompt' to `pre-command-hook' at a depth of 70 in the current buffer. (erc-keep-place-mode, erc-keep-place-enable): Change hook depth from 0 to 85. (erc--keep-place-indicator-setup): Add overlay arrow `after-string' in non-graphical settings in case users have time stamps or other content occupying the left margin. (erc-keep-place-indicator-mode, erc-keep-place-indicator-enable): Change hook depth from 90 to 85 locally so as not to conflict with a value of t, for append. (erc--keep-place-indicator-on-global-module): Change hook depth from 90 to 85 locally. * test/lisp/erc/erc-scenarios-scrolltobottom-relaxed.el: New file. * test/lisp/erc/erc-scenarios-scrolltobottom.el: New file. * test/lisp/erc/resources/erc-scenarios-common.el (erc-scenarios-common--term-size, erc-scenarios-common--run-in-term, erc-scenarios-common-interactive-debug-term-p, erc-scenarios-common-with-noninteractive-in-term): New test macro and supporting helper function and variables to facilitate running scenario-based tests in an inferior Emacs, in term-mode. (erc-scenarios-common--at-win-end-p, erc-scenarios-common--above-win-end-p, erc-scenarios-common--prompt-past-win-end-p, erc-scenarios-common--recenter-top-bottom-around, erc-scenarios-common--recenter-top-bottom, erc-scenarios-scrolltobottom--normal): New test fixture and assertion helper functions. * test/lisp/erc/resources/scrolltobottom/help.eld: New file.

Add text props for CTCP messages and speakers in ERC * etc/ERC-NEWS: Mention reduction in boldness of `erc-notice-face' and `erc-action-face'. * lisp/erc/erc-fill.el (erc-fill-spaced-commands, erc-fill--spaced-commands): Rename former to latter and demote from user option to internal variable. (erc-fill): Change `erc-fill-spaced-commands' to `erc-fill--spaced-commands'. (erc-fill--wrap-continued-message-p): Use more precise `erc-ctcp' text prop instead of face-based heuristic to detect CTCP ACTION message. (erc-fill--wrap-action-dedent-p): New variable to toggle whether `line-prefix' is applied to CTCP ACTION messages. This exists less to accommodate user preferences and more for third-party code that assumes the first non-whitespace span in every message is a nick. (erc-fill-wrap): Look for `erc-speaker' property before falling back on word at point. Use `erc-ctcp' to detect CTCP ACTION messages. * lisp/erc/erc.el (erc-notice-face, erc-action-face): Prefer weight of `semi-bold' when available so that buttonization is at least somewhat perceptible in notices and action messages. (erc-send-action): Ensure nickname passed to `erc-display-message' has `erc-speaker' property and `erc-ctcp' ACTION property. (erc--own-property-names): Add `erc-speaker' to lineup. (erc-format-privmessage): Don't clobber `erc-nick-prefix-face'. That is, retain face applied to a leading stretch of characters in the `nick' parameter, but continue to discard trailing faces. (erc-format-my-nick, erc-ctcp-query-ACTION): Add new text property `erc-speaker' to the nick portion of the formatted speaker label. Do this to assist modules, like `button' and `match', that currently re-parse speakers in inserted messages. (erc-process-ctcp-query): Add `erc-ctcp' property to entire message before insertion hooks see it. * test/lisp/erc/erc-fill-tests.el (erc-fill-tests--compare): Warn about certain unreliable comparisons if generalizing helper for use by other modules. * test/lisp/erc/erc-tests.el (erc-tests--equal-including-properties): New helper compat macro. (erc-format-privmessage): New test. (Bug#64301)
2023-06-25 01:33:20 +00:00
** Subtle changes in two fundamental faces.
Users of the default theme may notice that 'erc-action-face' and
'erc-notice-face' now appear slightly less bold on systems supporting
a weight of 'semi-bold'. This was done to make buttons detectable and
to spare users from resorting to tweaking these faces, or options like
'erc-notice-highlight-type', just to achieve this effect.
Preserve prompt in erc-cmd-CLEAR * etc/ERC-NEWS: Mention behavioral changes to functionality provided by the `truncate' and `log' modules and also the "/CLEAR" command. * lisp/erc/erc-log.el (erc-truncate-buffer-on-save): Deprecate option because three's a crowd, and ERC already has a dedicated module as well as a slash command for this purpose. And although this commit restores functionality, this option has been unusable since at least the release of ERC 5.5, with no known complaints received thus far. Also, the doc string of `erc-save-buffer-in-logs' makes no mention of this feature WRT interactive invocations or otherwise. (erc-log-mode, erc-log-enable, erc-log-disable): Subscribe to new internal hook `erc--pre-clear-functions'. (erc-log--save-in-progress-p): New variable to help restore `erc-truncate-buffer-on-save' and promote code reuse. (erc-logging-enabled): Guard with `erc-log--saved-in-progress-p'. (erc-save-buffer-in-logs): Overload `buffer' parameter to allow various hooks to supply a non-buffer as well. Warn when people use `erc-truncate-buffer-on-save', which is now deprecated. * lisp/erc/erc-stamp.el (erc-stamp-mode, erc-stamp-enable, erc-stamp-disable): Subscribe to `erc--pre-clear-functions'. (erc-stamp--update-saved-position): New function for updating last-logged marker on `erc-stamp--insert-date-function'. (erc-stamp--reset-on-clear): New function to forget last inserted stamps when truncating. * lisp/erc/erc-truncate.el (erc-truncate-mode, erc-truncate-enable, erc-truncate-disable): Use `erc-insert-done-hook' instead of `erc-insert-post-hook', as implicitly suggested by an ancient comment, which ponders whether truncating the buffer at the insertion phase may be harmful to other hook members. (erc-truncate-buffer-to-size): Set truncation boundary at message break instead of line break. Run `erc--pre-clear-functions'. (erc-truncate-buffer): Save excursion. This should probably be handled by `erc-truncate-buffer-to-size' instead, but that's likelier to cause breakage in third-party code. * lisp/erc/erc.el (erc--pre-clear-functions): New internal hook. (erc-cmd-CLEAR): Run `erc--pre-clear-functions' before clearing, and don't blow away prompt. The latter was a regression caused by 05f6fdb9e78 "Preserve ERC prompt and its bounding markers". * test/lisp/erc/erc-scenarios-log.el: New file. (Bug#60936)
2023-05-29 04:16:39 +00:00
** Improved interplay between buffer truncation and message logging.
While most of these improvements are subtle, some affect everyday use.
For example, users of the 'truncate' module may notice that truncation
now happens between messages rather than arbitrary lines. And those
with the default 'erc-insert-timestamp-left-and-right' for their
'erc-insert-timestamp-function' will see date stamps reprinted after
every "/CLEAR" but omitted from any logs. One notable casualty of
these changes has been the deprecation of the ancient option
'erc-truncate-buffer-on-save'. Users of the 'log' module can achieve
the same effect by issuing a "/CLEAR" at the prompt.
** The 'truncate' module no longer enables logging automatically.
Users expecting 'truncate' to perform logging based on the option
'erc-enable-logging' need to instead add 'log' to 'erc-modules' for
continued integration. With the existing design, merely loading the
library 'erc-log' caused 'truncate' to start writing logs, possibly
against a user's wishes.
Add optional timezone param to erc-echo-timestamp * etc/ERC-NEWS: Move `erc-echo-timestamp' from misc section to own entry, and mention option `erc-echo-timestamp-zone'. * lisp/erc/erc-stamp.el (erc-echo-timestamps): Mention that some finagling is required if enabling this option after activating the module. (erc-echo-timestamp-format): Add additional Custom choice constants and make the existing default one of them. (erc-echo-timestamp-zone): New option to specify timezone for option `erc-echo-timestamps' and function `erc-echo-timestamp'. (erc-stamp-mode, erc-stamp-enable, erc-stamp-disable): Call `erc-stamp--setup' instead of `erc-munge-invisibility-spec'. (erc-stamp--current-time): Use `current-time' instead of `erc-current-time'. (erc-add-timestamp): Improve readability slightly, and change `fboundp' to `functionp' to avoid signaling an error when the variable's value is not a symbol. (erc-munge-invisibility-spec): Perform teardown when boolean flag options, like `erc-timestamp-intangible' and `erc-echo-timestamps' are nil. (erc-stamp--setup): Call `erc-munge-invisibility-spec', possibly binding timestamp options to nil to force a tear down). (erc-stamp--last-stamp, erc-stamp--on-clear-message): New function and helper state variable to tell Emacs not to clear the current timestamp message when navigating within the same IRC message. (erc-echo-timestamp): Add optional `zone' parameter, to be passed directly to `format-time-string', when non-interactive, and massaged sensibly otherwise. Set the local variable `erc-stamp--last-stamp'. * test/lisp/erc/erc-stamp-tests.el (erc-echo-timestamp): New test. (Bug#60936)
2023-08-31 06:15:22 +00:00
** The function 'erc-echo-timestamp' is now a command.
The option 'erc-echo-timestamps' (plural) has always enabled the
contextual printing of timestamps to the echo area when moving between
messages in an ERC buffer. Similar functionality is now available on
demand by invoking the newly interactive function 'erc-echo-timestamp'
atop any message. The new companion option 'erc-echo-timestamp-zone'
determines the default timezone when not specified with a prefix
argument.
** Option 'erc-remove-parsed-property' deprecated.
This option's nil behavior serves no practical purpose yet has the
potential to degrade the user experience by competing for space with
forthcoming features powered by next generation extensions. Anyone
with a legitimate use for this option likely also possesses the
knowledge to rig up a suitable analog with minimal effort. That said,
the road to removal is long.
Improve erc-warn-about-blank-lines behavior * etc/ERC-NEWS: Mention more detailed feedback when option `erc-warn-about-blank-lines' is non-nil. * lisp/erc/erc-common.el (erc--input-split): Add `abortp' slot to allow a premature exit while validating prompt input. * lisp/erc/erc.el (erc-warn-about-blank-lines): Clarify meaning of "blank lines" in doc string, and mention interaction with companion option `erc-send-whitespace-lines'. (erc-inhibit-multiline-input): Fix inaccurate description in doc string. (erc--input-review-functions): Move `erc--discard-trailing-multiline-nulls' to end of list, after `erc--run-input-validation-checks' so that the latter doesn't have to resplit the original input string in order to issue feedback. (erc--blank-in-multiline-input-p): Remove unused internal function originally slated to be part of ERC 5.6. (erc--check-prompt-input-for-something): New trivial validation function to check if the input is empty. (erc--count-blank-lines): New function that tallies up the number of blank and whitespace-only lines in the current input. One downside of this design is that this function's conclusions aren't shared with `erc--discard-trailing-multiline-nulls', which must decide on its own how many lines to strip. (erc--check-prompt-explanation): New variable. (erc--check-prompt-input-for-multiline-blanks): Rework significantly to provide more informative messages and more sensible behavior for common cases with respect to relevant option values. (erc--check-prompt-input-functions): Add new validation function `erc--check-prompt-for-something'. (erc--run-input-validation-checks): Set `abortp' slot of `erc--input-split' when hooks return a non-string, rather than generate an unhelpful fallback message. Also print a message when the variable `erc--check-prompt-explanation' is non-nil. (erc-send-current-line): When the `abortp' slot of the current `erc--input-split' object is non-nil, forgo normal input processing. This fixes a regression in 5.6-git, which previously emitted an error message when it should have just exited the command. (erc--discard-trailing-multiline-nulls): Always run, regardless of `erc-send-whitespace-lines', and leave a blank line behind when stripping a message consisting of only blank lines. (erc--run-send-hooks): Always run hooks and surrounding logic rather than only when hooks are populated. * test/lisp/erc/erc-tests.el (erc--refresh-prompt): Add assertion and use default value for `erc--input-review-functions'. (erc-ring-previous-command): Use default value for `erc--input-review-functions' and ensure `erc-current-nick' does not error. (erc--blank-in-multiline-input-p): Remove obsolete test. (erc--check-prompt-input-functions): Update expected message. (erc--discard-trailing-multiline-nulls, erc--count-blank-lines): New tests. (erc-tests--check-prompt-input--expect, erc-tests--check-prompt-input-messages): New helper variables. (erc--check-prompt-input-for-multiline-blanks, erc--check-prompt-input-for-multiline-blanks/explanations): New tests. (erc-send-whitespace-lines): Expect hook-processing logic to pad empty lines instead of deferring to `erc-send-input-line-function'. (Bug#66073)

Enabled by default, this option now produces more useful feedback
whenever ERC rejects prompt input containing whitespace-only lines.
When paired with option 'erc-send-whitespace-lines', ERC echoes a
tally of blank lines padded and trailing blanks culled.
** Miscellaneous UX changes.
Some minor quality-of-life niceties have finally made their way to
Add optional timezone param to erc-echo-timestamp * etc/ERC-NEWS: Move `erc-echo-timestamp' from misc section to own entry, and mention option `erc-echo-timestamp-zone'. * lisp/erc/erc-stamp.el (erc-echo-timestamps): Mention that some finagling is required if enabling this option after activating the module. (erc-echo-timestamp-format): Add additional Custom choice constants and make the existing default one of them. (erc-echo-timestamp-zone): New option to specify timezone for option `erc-echo-timestamps' and function `erc-echo-timestamp'. (erc-stamp-mode, erc-stamp-enable, erc-stamp-disable): Call `erc-stamp--setup' instead of `erc-munge-invisibility-spec'. (erc-stamp--current-time): Use `current-time' instead of `erc-current-time'. (erc-add-timestamp): Improve readability slightly, and change `fboundp' to `functionp' to avoid signaling an error when the variable's value is not a symbol. (erc-munge-invisibility-spec): Perform teardown when boolean flag options, like `erc-timestamp-intangible' and `erc-echo-timestamps' are nil. (erc-stamp--setup): Call `erc-munge-invisibility-spec', possibly binding timestamp options to nil to force a tear down). (erc-stamp--last-stamp, erc-stamp--on-clear-message): New function and helper state variable to tell Emacs not to clear the current timestamp message when navigating within the same IRC message. (erc-echo-timestamp): Add optional `zone' parameter, to be passed directly to `format-time-string', when non-interactive, and massaged sensibly otherwise. Set the local variable `erc-stamp--last-stamp'. * test/lisp/erc/erc-stamp-tests.el (erc-echo-timestamp): New test. (Bug#60936)

ERC. For example, fool visibility has become togglable with the new
Respect existing invisibility props in erc-stamp * etc/ERC-NEWS: mention `erc-match-toggle-hidden-fools' and new merging behavior when handling `invisible' text property. * lisp/erc/erc-match.el (erc-hide-fools): change `invisible' property to `erc-match' for all messages, not just those with offset bounds. (erc-match--modify-invisibility-spec): Fix error in doc string. (erc-match-toggle-hidden-fools): New command. * lisp/erc/erc-stamp.el (erc-stamp--invisible-property): Add new internal variable to hold existing `invisible' property merged with the one registered by this module, the non-namespaced `timestamp'. (erc-stamp--skip-when-invisible): Add new internal variable, an escape hatch for pre-ERC-5.6 behavior in which timestamps were not applied at all to invisible messages. This led to strange-looking, uneven logs, and it prevented other modules from offering toggle functionality for invisibility-spec members registered to them. (erc-add-timestamp): Merge with existing `invisible' property, when present, instead of clobbering, but only when escape hatch `erc-stamp--skip-when-invisible' is nil. (erc-insert-timestamp-left, erc-format-timestamp): Use possibly merged `invisible' prop value. Don't bother with `isearch-open-invisible', which only affects overlays. (erc-insert-timestamp-right): Bind `buffer-invisibility-spec' to nil when figuring `current-column'. Apply `invisible' text prop to white space around stamp. * test/lisp/erc/erc-scenarios-match.el: Require `erc-fill' and `erc-stamp'. (erc-scenarios-match--invisible-stamp): Move common setup and core assertions for some stamp and invisibility-related tests into a fixture-like helper. (erc-scenarios-match--stamp-left-fools-invisible): Fix temporarily disabled test and use fixture. (erc-scenarios-match--find-eol): New helper. (erc-scenarios-match--stamp-right-fools-invisible, erc-scenarios-match--stamp-right-invisible-fill-wrap, erc-scenarios-match--stamp-both-invisible-fill-static): New tests. (Bug#64301)

command 'erc-match-toggle-hidden-fools'. The 'button' module's
'erc-button-previous' now moves to the beginning instead of the end of
buttons. A new command, 'erc-news', can be invoked to visit this very
file. And the 'irccontrols' module now supports additional colors and
special handling for "spoilers" (hidden text).
** Changes in the library API.
*** Some top-level dependencies have been removed.
The library 'erc-goodies' is no longer loaded by ERC's main library.
This was done to further cement the move toward a unidirectional
dependency flow begun in 5.5. Additionally, a few barely used and
newly introduced dependencies are now lazily loaded, which may upset
some third-party code. The first of these is 'pp' because its
'pp-to-string' is autoloaded in all supported ERC versions. Also gone
are 'thingatpt', 'time-date', and 'iso8601'. All were used ultra
sparingly, and the latter two have only been around for one minor
release cycle, so their removal hopefully won't cause much churn.
*** Some ERC-applied text properties have changed.
Chiefly, 'rear-sticky' has been replaced by 'erc-command', which
records the IRC command (or numeric) associated with a message. Less
impactfully, the value of the 'field' property for ERC's prompt has
changed from 't' to the more useful 'erc-prompt', although the
Make erc-fill-wrap work with left-sided stamps * etc/ERC-NEWS: Remove all mention of option `erc-timestamp-align-to' supporting a value of `margin', which has been abandoned. Do mention leading white space before stamps now having stamp-related properties. * lisp/erc/erc-backend.el (erc--reveal-prompt, erc--conceal-prompt): New generic functions with default implementations factored out from `erc--unhide-prompt' and `erc--hide-prompt'. (erc--prompt-hidden-p): New internal predicate function. (erc--unhide-prompt): Defer to `erc--reveal-prompt', and set `erc-prompt' text property to t. (erc--hide-prompt): Defer to `erc--conceal-prompt', and set `erc-prompt' text property to `hidden'. * lisp/erc/erc-compat.el (erc-compat--29-browse-url-irc): Don't use `function-equal'. * lisp/erc/erc-fill.el (erc-fill-wrap-margin-width, erc-fill-wrap-margin-side): New options to control side and initial width of `fill-wrap' margin. (erc-fill--wrap-beginning-of-line): Fix bug involving non-string valued `display' props. (erc-fill-wrap-toggle-truncate-lines): New command to re-enable `visual-line-mode' when toggling off `truncate-lines'. (erc-fill-wrap-mode-map): Remap `toggle-truncate-lines' to `erc-fill-wrap-toggle-truncate-lines'. (erc-fill-wrap-mode, erc-fill-wrap-enable, erc-fill-wrap-disable): Update doc string, persist a few local vars, and conditionally set `erc-stamp--margin-left-p'. When deactivating, disable `visual-line-mode' first. (erc-fill--wrap-continued-message-p): Use `erc-speaker' instead of heuristics when comparing nicks between consecutive messages. (erc-fill-wrap-nudge): Update doc string and account for left-sided stamps. (erc-timestamp-offset): Add comment regarding conditional guard based on function-valued option. * lisp/erc/erc-stamp.el (erc-timestamp-use-align-to): Remove value variant `margin', which was originally intended to be new in ERC 5.6. This functionality was all but useless without the internal minor mode `erc-stamp--display-margin-mode' active. (erc-stamp-right-margin-width): Remove unused option new in 5.6. (erc-stamp--display-margin-force): Remove unused function. (erc-stamp--margin-width, erc-stamp--margin-left-p): New internal variables. (erc-stamp--init-margins-on-connect): New function for initializing mode-managed margin after connecting. (erc-stamp--adjust-right-margin, erc-stamp--adjust-margin): Rename function to latter and accommodate left-hand stamps. (erc-stamp--inherited-props): Move definition higher up in same file. (erc-stamp--display-margin-mode): Update function name, and adjust setup and teardown to accommodate left-handed stamps. Don't add advice around `erc-insert-timestamp-function'. (erc-stamp--last-prompt, erc-stamp--display-prompt-in-left-margin): New function and helper var to convert a normal inserted prompt so that it appears in the left margin. (erc-stamp--refresh-left-margin-prompt): Helper for other modules to quickly refresh prompt outside of insert hooks. (erc--reveal-prompt, erc--conceal-prompt): New implementations for when `erc-stamp--display-margin-mode' is active. (erc-insert-timestamp-left): Convert to generic function and provide implementation for `erc-stamp--display-margin-mode'. (erc-stamp--omit-properties-on-folded-lines): New variable, an escape hatch for propertizing white space before right-side stamps folded over onto another line. (erc-insert-timestamp-right): Don't expect `erc-timestamp-align-to' to ever be the symbol `margin'. Move handling for that case to one contingent on the internal minor mode `erc-stamp--display-margin-mode' being active. Add text properties preceding stamps that occupy a line by their lonesome. See related news entry for rationale. This is arguably a breaking change. * lisp/erc/erc.el (erc--refresh-prompt-hook): New hook variable for modules to adjust prompt properties whenever it's refreshed. (erc--refresh-prompt): Fix bug in which user-defined prompt functions failed to hide when quitting in server buffers. Run new hook `erc--refresh-prompt-hook'. (erc-display-prompt): Add comment noting that the text property `erc-prompt' now actually matters: it's t while a session is running and `hidden' when disconnected. * test/lisp/erc/erc-fill-tests.el (erc-fill--left-hand-stamps): New test. * test/lisp/erc/erc-stamp-tests.el (erc-stamp-tests--use-align-to--nil, erc-stamp-tests--use-align-to--t): New functions forged from old test bodies to allow optionally asserting pre-5.6 behavior regarding leading white space on right-hand stamps that exist on their own line. (erc-timestamp-use-align-to--nil, erc-timestamp-use-align-to--t): Parameterize with compatibility flag. (erc-timestamp-use-align-to--margin, erc-stamp--display-margin-mode--right): Rename test to latter. * test/lisp/erc/erc-tests.el (erc-hide-prompt): Add some assertions for new possible value of `erc-prompt' text property. * test/lisp/erc/resources/fill/snapshots/stamps-left-01.eld: New test data file. (Bug#60936)

property of the same name has been retained and now has a value of
'hidden' when disconnected.
*** Members of insert- and send-related hooks have been reordered.
Built-in and third-party modules rely on certain hooks for adjusting
incoming and outgoing messages upon insertion. And some modules only
want to do so after others have done their damage. Traditionally,
Consider all windows in erc-scrolltobottom-mode * etc/ERC-NEWS: Add entry for option `erc-scrolltobottom-all', and mention explicit hook-depth intervals reserved by ERC. * lisp/erc/erc-backend.el (erc--hide-prompt): Change hook depth on `pre-command-hook' from 91 to 80. * lisp/erc/erc-goodies.el (erc-input-line-position): Mention secondary role when new option `erc-scroll-to-bottom-relaxed' is non-nil. (erc-scrolltobottom-all): New option that decides whether module `scrolltobottom' affects all windows or just the selected one, as it always has. (erc-scrolltobottom-relaxed): New option to leave the prompt stationary instead of forcing it to the bottom of the window. (erc-scrolltobottom-mode, erc-scrolltobottom-enable, erc-scrolltobottom-disable): Use `erc--scrolltobottom-setup' instead of `erc-add-scroll-to-bottom' for adding and removing local hooks and instead of ranging over buffers when removing them. Also add and remove new hook members when `erc-scrolltobottom-all' is non-nil. (erc--scrolltobottom-relaxed-commands, erc--scrolltobottom-window-info, erc--scrolltobottom-post-force-commands, erc--scrolltobottom-relaxed-skip-commands): New internal variables. (erc--scrolltobottom-on-pre-command erc--scrolltobottom-on-post-command): New functions resembling `erc-possibly-scroll-to-bottom' that try to avoid scrolling repeatedly for no reason. (erc--scrolltobottom-on-pre-command-relaxed, erc--scrolltobottom-on-post-command-relaxed): New commands to help implement `erc-scroll-to-bottom-relaxed'. (erc--scrolltobottom-at-prompt-minibuffer-active): New function to scroll to bottom on window configuration changes when using the minibuffer. (erc--scrolltobottom-all): New function to scroll all windows displaying the current buffer. (erc-add-scroll-to-bottom): Deprecate this function because it is now unused in the default client and trivial to implement otherwise. (erc--scrolltobottom-setup): New generic function to perform teardown as well as setup depending on the state of the module's mode variable. Also add an implementation specifically for `erc-scrolltobottom-all' that locally modifies different sets of hooks depending on `erc-scrolltobottom-relaxed'. (erc--scrolltobottom-on-pre-insert): New generic function that remembers the last `window-start' and maybe the current screen line before inserting a message, in order to restore it afterward. (erc--scrolltobottom-confirm): New function, a replacement for `erc-scroll-to-bottom' that returns non-nil when it's actually recentered the window. For now, used only when `erc-scrolltobottom-all' is enabled. (erc-move-to-prompt-setup): Add `erc-move-to-prompt' to `pre-command-hook' at a depth of 70 in the current buffer.

(erc--keep-place-indicator-setup): Add overlay arrow `after-string' in non-graphical settings in case users have time stamps or other content occupying the left margin. (erc-keep-place-indicator-mode, erc-keep-place-indicator-enable): Change hook depth from 90 to 85 locally so as not to conflict with a value of t, for append.

this has required various hacks and finagling to achieve. And while
this release makes an effort to load modules in a more consistent
order, that alone isn't enough to ensure similar predictability among
essential members of important hooks.
Luckily, ERC now leverages a feature introduced in Emacs 27, "hook
depth," to secure the positions of a few key members of
'erc-insert-modify-hook' and 'erc-send-modify-hook'. So far, this
includes the functions 'erc-button-add-buttons', 'erc-match-message',
'erc-fill', and 'erc-add-timestamp', which now appear in that order,
when present, at depths beginning at 20 and ending below 80. Of most
interest to module authors is the new relative positioning of the
first three, which have been rotated leftward with respect to their
previous places in recent ERC versions (fill, button, match ,stamp).

ERC also provisionally reserves the same depth interval for
'erc-insert-pre-hook' and possibly other, similar hooks, but will

in new code.

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'.

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'.

*** A singular entry point for inserting messages.
Displaying "local" messages, like help text and interactive-command
feedback, in ERC buffers has never been straightforward. As such,
ancient patterns, like the pairing of preformatted "notice" text with
ERC's oldest insertion function, 'erc-display-line', still appear
quite frequently in the wild despite having been largely phased out of
ERC's own code base in 2002. That this example has endured makes some
sense because it's probably seen as less cumbersome than fiddling with
the more powerful and complicated 'erc-display-message'.
The latest twist in this saga comes with this release, in which a
healthy bit of "pre-insertion" business has taken up residence in
'erc-display-message'. While this would seem to put antiquated
patterns, like the above mentioned 'erc-make-notice' combo, at risk of
having messages ignored or subject to degraded treatment by built-in
modules, an adaptive measure has been introduced that recasts
'erc-display-line' as a thin wrapper around 'erc-display-message'.
And though nothing of the sort has been done for the lower-level
'erc-display-line-1' (now an obsolete alias for 'erc-insert-line'),
some last-ditch fallback code is in place to ensure baseline
functionality. As always, if you find these developments disturbing,
please say so on the tracker.
*** ERC now manages timestamp-related properties a bit differently.
Manage some text props for ERC insertion-hook members * etc/ERC-NEWS: Mention that ERC only adds the text property `cursor-sensor-functions' when `erc-echo-timestamps' is enabled. Also mention that date stamps are now inserted as separate messages. * lisp/erc/erc-fill.el (erc-fill): Look for text prop `erc-cmd' instead of `erc-command' and use helper utility to do so. (erc-fill-static): Skip date stamps because this fill style leaves them flush left. (erc-fill-wrap-mode, erc-fill-wrap-enable, erc-fill-wrap-disable): Don't hook on the soon-to-be-removed function interface `erc-stamp--insert-date-function' because date stamps are now separate messages. (erc-fill--wrap-continued-message-p): Restore accidentally discarded doc string. Derive context about current message from text props at `point-min', and use updated property names and utility functions. Abort when previous message is now hidden. (erc-fill--wrap-stamp-insert-prefixed-date): Remove unused function, originally meant to be new in ERC 5.6, and move logic for date-stamp measuring portion directly to `erc-fill-wrap' itself. (erc-fill--wrap-measure): New helper function. (erc-fill-wrap): Use helper `erc-fill--wrap-measure' and incorporate date-stamp detection and width measuring from removed helper. Don't dedent first word for messages of unknown origin, such as those inserted by `erc-display-line' alone without prior preparation from `erc-display-message'. * lisp/erc/erc-goodies.el (erc-readonly-mode, erc-readonly-enable): Set hook depth explicitly to 70. * lisp/erc/erc-stamp.el (erc-timestamp-format-left): Mention that a trailing newline is implicit if not provided and that users who don't want date stamps should use `erc-timestamp-format-right' instead. (erc-stamp-mode, erc-stamp-enable): Call `erc-stamp--setup' instead of `erc-munge-invisibility-spec', and bump hook depth for `erc-add-timestamp' to 70. (erc-stamp--current-time): Use `erc-ts' instead of `erc-timestamp' text property in doc string. (erc-stamp--skip): New internal variable. (erc-stamp--allow-unmanaged): New variable for legacy code to force `erc-add-timestamps' to run when `erc--msg-props' is nil. (erc-add-timestamp): Always run when `erc-stamp--allow-unmanaged' is non-nil unless `erc-stamp--skip' is as well because the latter takes precedence. Don't add `erc-ts' text prop directly unless `erc-stamp--allow-unmanaged is non-nil. Instead, use the new `erc--msg-props' facility to defer until after modification hooks. Likewise, don't add `cursor-senor-functions' directly either unless the same compatibility flag is enabled. Instead, expect the latter to be handled by a post-modify hook conditioned on the option `erc-echo-timestamps'. (erc-timestamp-last-inserted-left): Mention that the final trailing newline specified in the format string no longer appears in the recorded value. (erc-stamp-prefix-log-filter): Use updated name for timestamp property as well as helper utility for accessing it. (erc-stamp--inherited-props): Add doc string. (erc-insert-timestamp-right): Fix bug involving object cycle where the time-stamp string would appear in its own `display' property. (erc-stamp--insert-date-function, erc-stamp--insert-date-hook): Remove unused internal function-valued interface variable and replace with the latter, a normal hook. (erc-stamp--date-format-end, erc-stamp--propertize-left-date-stamp): New function and auxiliary variable to apply date stamp properties at the post-modify stage. Add text property `erc-stamp-type' to inserted date stamps to help folks distinguish between them and other left-sided stamps. (erc-stamp--current-datestamp-left, erc-stamp--format-date-stamp, erc-stamp--insert-date-stamp-as-phony-message, erc-stamp--lr-date-on-pre-modify): New functions and state variable to help ERC treat date stamps as separate messages while working within the established mechanism for processing inserted messages. Shadow `erc-stamp--invisible-property' when calling `erc-format-timestamp' in order to prevent date stamps from inheriting other `invisible' props. These date stamps are special in that they have no business being hidden along with the current message. (erc-insert-timestamp-left-and-right): On initial run in any buffer, remember whether the date stamp needed newline massaging on insertion.

module init. And when present, the property's value no longer
contains unique closures and thus no longer proves effective for
Manage some text props for ERC insertion-hook members * etc/ERC-NEWS: Mention that ERC only adds the text property `cursor-sensor-functions' when `erc-echo-timestamps' is enabled. Also mention that date stamps are now inserted as separate messages. * lisp/erc/erc-fill.el (erc-fill): Look for text prop `erc-cmd' instead of `erc-command' and use helper utility to do so. (erc-fill-static): Skip date stamps because this fill style leaves them flush left. (erc-fill-wrap-mode, erc-fill-wrap-enable, erc-fill-wrap-disable): Don't hook on the soon-to-be-removed function interface `erc-stamp--insert-date-function' because date stamps are now separate messages. (erc-fill--wrap-continued-message-p): Restore accidentally discarded doc string. Derive context about current message from text props at `point-min', and use updated property names and utility functions. Abort when previous message is now hidden. (erc-fill--wrap-stamp-insert-prefixed-date): Remove unused function, originally meant to be new in ERC 5.6, and move logic for date-stamp measuring portion directly to `erc-fill-wrap' itself. (erc-fill--wrap-measure): New helper function. (erc-fill-wrap): Use helper `erc-fill--wrap-measure' and incorporate date-stamp detection and width measuring from removed helper. Don't dedent first word for messages of unknown origin, such as those inserted by `erc-display-line' alone without prior preparation from `erc-display-message'. * lisp/erc/erc-goodies.el (erc-readonly-mode, erc-readonly-enable): Set hook depth explicitly to 70. * lisp/erc/erc-stamp.el (erc-timestamp-format-left): Mention that a trailing newline is implicit if not provided and that users who don't want date stamps should use `erc-timestamp-format-right' instead. (erc-stamp-mode, erc-stamp-enable): Call `erc-stamp--setup' instead of `erc-munge-invisibility-spec', and bump hook depth for `erc-add-timestamp' to 70. (erc-stamp--current-time): Use `erc-ts' instead of `erc-timestamp' text property in doc string. (erc-stamp--skip): New internal variable. (erc-stamp--allow-unmanaged): New variable for legacy code to force `erc-add-timestamps' to run when `erc--msg-props' is nil. (erc-add-timestamp): Always run when `erc-stamp--allow-unmanaged' is non-nil unless `erc-stamp--skip' is as well because the latter takes precedence. Don't add `erc-ts' text prop directly unless `erc-stamp--allow-unmanaged is non-nil. Instead, use the new `erc--msg-props' facility to defer until after modification hooks. Likewise, don't add `cursor-senor-functions' directly either unless the same compatibility flag is enabled. Instead, expect the latter to be handled by a post-modify hook conditioned on the option `erc-echo-timestamps'. (erc-timestamp-last-inserted-left): Mention that the final trailing newline specified in the format string no longer appears in the recorded value.

(erc-stamp--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.

traversing inserted messages. For now, ERC only provides an internal
means of visiting messages, but a public interface is forthcoming.
Also affecting the 'stamp' module is the deprecation of the function
'erc-insert-aligned' and its removal from client code. Additionally,
the module now merges its 'invisible' property with existing ones and
includes all white space around stamps when doing so.
This "propertizing" of surrounding white space also extends to all
'stamp'-applied properties, like 'field', in all intervening space
between message text and timestamps. Technically, this constitutes a

(erc-timestamp-offset): Add comment regarding conditional guard based on function-valued option. * lisp/erc/erc-stamp.el (erc-timestamp-use-align-to): Remove value variant `margin', which was originally intended to be new in ERC 5.6. This functionality was all but useless without the internal minor mode `erc-stamp--display-margin-mode' active. (erc-stamp-right-margin-width): Remove unused option new in 5.6. (erc-stamp--display-margin-force): Remove unused function. (erc-stamp--margin-width, erc-stamp--margin-left-p): New internal variables.

(erc-insert-timestamp-right): Don't expect `erc-timestamp-align-to' to ever be the symbol `margin'. Move handling for that case to one contingent on the internal minor mode `erc-stamp--display-margin-mode' being active. Add text properties preceding stamps that occupy a line by their lonesome. See related news entry for rationale. This is arguably a breaking change. * lisp/erc/erc.el (erc--refresh-prompt-hook): New hook variable for modules to adjust prompt properties whenever it's refreshed. (erc--refresh-prompt): Fix bug in which user-defined prompt functions failed to hide when quitting in server buffers. Run new hook `erc--refresh-prompt-hook'. (erc-display-prompt): Add comment noting that the text property `erc-prompt' now actually matters: it's t while a session is running and `hidden' when disconnected. * test/lisp/erc/erc-fill-tests.el (erc-fill--left-hand-stamps): New test. * test/lisp/erc/erc-stamp-tests.el (erc-stamp-tests--use-align-to--nil, erc-stamp-tests--use-align-to--t): New functions forged from old test bodies to allow optionally asserting pre-5.6 behavior regarding leading white space on right-hand stamps that exist on their own line.

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.

*** Date stamps are independent messages.
ERC now inserts "date stamps" generated from the option
'erc-timestamp-format-left' as separate, standalone messages. (This
only matters if 'erc-insert-timestamp-function' is set to its default
value of 'erc-insert-timestamp-left-and-right'.) ERC's near-term UI
goals require exposing these stamps to existing code designed to
operate on complete messages. For example, users likely expect date
stamps to be togglable with 'erc-toggle-timestamps' while also being
immune to hiding from commands like 'erc-match-toggle-hidden-fools'.
Before this change, meeting such expectations demanded brittle
heuristics that checked for the presence of these stamps in the
leading portion of message bodies as well as special casing to act on
these areas without inflicting collateral damage. It may also be
worth noting that as consequence of these changes, the internally
managed variable 'erc-timestamp-last-inserted-left' no longer records
the final trailing newline in 'erc-timestamp-format-left'.
*** The role of a module's Custom group is now more clearly defined.
Associating built-in modules with Custom groups and provided library
features has improved. More specifically, a module's group now enjoys
the singular purpose of determining where the module's minor mode
variable lives in the Customize interface. And although ERC is now
slightly more adept at linking these entities, third-parties are still
encouraged to keep a module's name aligned with its group's as well as
the provided feature of its containing library, if only for the usual
reasons of namespace hygiene and discoverability.
*** ERC supports arbitrary CHANTYPES.
Specifically, channels can be prefixed with any predesignated
character, mainly to afford more flexibility to specialty services,
like bridges to other protocols.
*** 'erc-cmd-HELP' recognizes subcommands.
Some IRC "slash" commands are hierarchical and require users to
specify a subcommand to actually carry out anything of consequence.
Built-in modules can now provide more detailed help for a particular
subcommand by telling ERC to defer to a specialized handler.
*** Longtime quasi modules made proper.
The 'fill' module is now defined by 'define-erc-module'. The same
goes for ERC's imenu integration, which has 'imenu' now appearing in
the default value of 'erc-modules'.
Improve ERC's internal invisibility API * etc/ERC-NEWS: Mention that line endings have moved from the end to the beginning of hidden messages. * lisp/erc/erc-fill.el (erc-fill--wrap-ensure-dependencies): Warn when users have `erc-legacy-invisible-bounds-p' enabled, and force it to its default value of nil in the current buffer. (erc-fill-wrap-mode, erc-fill-wrap-enable): Move business involving compat variable for enabling legacy hidden-message behavior to helper. * lisp/erc/erc-match.el (erc-match--hide-fools-offset-bounds): Move internal variable from to main library file and rename to `erc-legacy-invisible-bounds-p'. Also make obsolete and flip semantics so a non-nil value enables the traditional behavior. (erc-match--hide-message): Move to main library file and rename to `erc--hide-message'. Add a property-value parameter instead of hard-coding to `erc-match'. Also, condition behavior on renamed compatibility flag `erc-legacy-invisible-bounds-p'. (erc-hide-fools): Call `erc--hide-message' with own value for `invisible' property specifically for fools. That is, use `match-fools' rather than `erc-match' or `erc-match-fools' to save room when visually inspecting. This retains the module name as a prefix to hopefully minimize collisions with invisibility spec members owned by non-ERC minor modes. The `timestamp' spec member owned by erc-stamp likewise lacks a namespace prefix, but its feature/group affiliation is self-evident. (erc-match--modify-invisibility-spec): Use toggle command non-interactively for adding and removing invisibility spec member. (erc-match-toggle-hidden-fools): Add explicit override argument and defer to general helper for actually modifying spec. (erc-match--toggle-hidden): New helper for toggling invisibility spec. * lisp/erc/erc.el (erc--merge-prop): If new value is a list, prepend onto existing. Add note about possible space optimization. (erc-legacy-invisible-bounds-p): New obsolete compat variable to enable traditional pre-5.6 invisibility interval on hidden messages. Replaces `erc-match--hide-fools-offset-bounds-p' but has an inverted meaning. The new default value of nil means invisibility covers a shifted interval consisting of the message body plus the line ending immediately preceding it. (erc--hide-message): New function, formerly `erc-match--hide-message' from erc-match.el introduced in ERC 5.6. * test/lisp/erc/erc-scenarios-match.el: (erc-scenarios-match--invisible-stamp): Fix comment and use API function in interactive convenience setup. (erc-scenarios-match--find-bol): New test helper. (erc-scenarios-match--find-eol): Fix bug affecting interactive use. (erc-scenarios-match--stamp-left-fools-invisible, erc-scenarios-match--stamp-right-fools-invisible, erc-scenarios-match--stamp-right-invisible-fill-wrap, erc-scenarios-match--stamp-both-invisible-fill-static): Update `invisible' property from `erc-match' to `match-fools'. (erc-scenarios-match--stamp-right-fools-invisible, erc-scenarios-match--stamp-both-invisible-fill-static): Move test body to function of same name for use in multiple cases. (erc-scenarios-match--stamp-right-fools-invisible--nooffset, erc-scenarios-match--stamp-both-invisible-fill-static--nooffset): New test variants asserting proper hiding with old pre-5.6 invisibility interval. * test/lisp/erc/erc-tests.el (erc-tests--equal-including-properties): Relocate macro higher in same file. (erc--merge-prop): New test. (Bug#64301)

*** Hidden messages contain a preceding rather than trailing newline.
ERC has traditionally only offered to hide messages involving fools,
but plans are to make hiding more powerful. Anyone depending on the
existing behavior should be aware that hidden messages now start and
end one character earlier, so that hidden line endings precede rather
than follow accompanying text. However, an escape hatch is available
in the variable 'erc-legacy-invisible-bounds-p'. It reinstates the
old behavior, which is unsupported by newer modules and features.
Optionally combine faces in erc-display-message * etc/ERC-NEWS: Tell module authors that `erc-display-message' can now combine faces. * lisp/erc/erc-button.el (erc-button--display-error-notice-with-keys): Ask `erc-display-message' to compose `erc-notice-face' and `erc-error-face'. * lisp/erc/erc-match.el (erc-hide-fools): Merge `invisible' prop `erc-match' with existing, if present, and move body to helper for hiding matched messages. (erc-match--hide-message): New helper function to hide messages regardless of match type. * lisp/erc/erc-track.el: (erc-track-faces-priority-list): Note in doc string that faces reserved for critical messages are always prioritized. Wrap :type declaration in macro helper to ensure `erc-button' is loaded beforehand. Otherwise calling `setopt' with the option's default value fails. (erc-track--attn-faces): Add new internal variable for faces that should always appear in the mode line, at least in the default client. (erc-track-modified-channels, erc-track-face-priority): Prepend `erc-track--attn-faces' to `erc-track-faces-priority-list'. * lisp/erc/erc.el (erc-send-action): Ask `erc-display-message' to apply both `erc-input-face' and `erc-action-face' to messages. (erc--compose-text-properties): New internal variable to act as flag for altering behavior of `erc-put-text-property'. (erc--merge-prop): New function copied from `erc-button-add-face' for general internal use with any text property by all of ERC. (erc-display-message-highlight): Set fallback face to `erc-default-face' the symbol instead of the string. For this to break third-party code, callers would have to supply erroneous types for nonexistent or undefined handlers and then explicitly check for and depend on such misuse, which seems unlikely and therefore not worth mentioning in etc/ERC-NEWS. (erc-display-message): Explain how `type' param works when it's a list. Fix code in type-as-list branch so that it optionally combines faces instead of clobbers them. (erc-put-text-property): Unalias from `put-text-property', but fall back to the latter unless caller wants to combine faces, in which case, defer to `erc--merge-prop'. * test/lisp/erc/erc-button-tests.el (erc-button--display-error-notice-with-keys): Expect a combined "error notice" face. (Bug#64301)
2023-06-25 01:33:20 +00:00
*** 'erc-display-message' optionally combines faces.
Users may notice that ERC now inserts some important error messages in
a combination of 'erc-error-face' and 'erc-notice-face'. This is
merely a consequence of 'erc-display-message' getting smarter about
how it treats face properties when its 'type' parameter is a list that
starts with t. Originally, ERC's authors intended to display both
server-originating and ERC-generated errors in this style, but that
intent was never realized. Though now possible, the effect has been
limited to special errors involving usage and internal state. For
third-party code, the key takeaway is that more 'font-lock-face'
properties encountered in the wild may be combinations of faces rather
than lone ones.
*** 'erc-pre-send-functions' visits prompt input post-split.
ERC now adjusts input lines to fall within allowed length limits
before showing hook members the result. For compatibility,
third-party code can request that the final input be adjusted again
prior to being sent. See doc string for details.
Preprocess prompt input linewise in ERC * etc/ERC-NEWS: Mention revised role of `erc-pre-send-functions' relative to line splitting. * lisp/erc/erc-common.el (erc-input): Add new slot `refoldp' to allow `erc-pre-send-functions' members to indicate that splitting should occur a second time after all members have had their say. (erc--input-split): Specify some defaults for overridden slots and explicitly declare some types for good measure. * lisp/erc/erc-goodies.el (erc-noncommands-mode, erc-noncommands-enable, erc-noncommands-disable): Replace `erc-pre-send-functions' with `erc--input-review-functions'. * lisp/erc/erc-ring.el (erc-ring-enable, erc-ring-disable, erc-ring-mode): Subscribe to `erc--input-review-functions' instead of `erc-pre-send-functions' for `erc--add-to-input-ring'. * lisp/erc/erc.el (erc-pre-send-functions): Note some nuances regarding line splitting in doc string and note that a new slot is available. (erc--pre-send-split-functions, erc--input-review-functions): Rename former to latter, while also obsoleting. Remove large comment. Add new default member `erc--run-input-validation-checks'. (erc-send-modify-hook): Replace the obsolete `erc-send-pre-hook' and `erc-send-this' with `erc-pre-send-functions' in doc string. (erc--check-prompt-input-for-excess-lines): Don't trim trailing blanks. Rework to also report overages in characters as well as lines. (erc--run-input-validation-hooks): New function to adapt an `erc--input-split' object to `erc--check-prompt-input-functions'. (erc-send-current-line): Run `erc--input-review-functions' in place of the validation hooks they've subsumed. Call `erc--send-input-lines' instead of the now retired but not deprecated `erc-send-input'. (erc--run-send-hooks, erc--send-input-lines): New functions that together form an alternate version of `erc-send-input'. They operate on input linewise but make accommodations for older interfaces. * test/lisp/erc/erc-tests.el (erc-ring-previous-command): Replace `erc-pre-send-functions' with `erc--input-review-functions'. (erc-tests--with-process-input-spy): Shadow `erc--input-review-functions'. (erc-check-prompt-input-for-excess-lines): Don't expect trailing blanks to be trimmed. (erc--run-send-hooks): New test.

*** ERC's prompt survives the insertion of user input and messages.
Previously, ERC's prompt and its input marker disappeared while
running hooks during message insertion, and the position of its
"insert marker" (ERC's per-buffer process mark) was inconsistent
during these spells. To make insertion handling more predictable in
preparation for incorporating various protocol extensions, the prompt
and its bounding markers have become perennial fixtures.
To effect this change, small behavioral differences in message
insertion have been adopted. Crucially, 'erc-insert-marker' now has
an "insertion type" of t, and 'erc-display-line-1' now calls 'insert'
instead of 'insert-before-markers. This allows user code running on
'erc-insert-modify-hook' and 'erc-insert-post-hook' to leave its own
markers at the actual insertion point instead of resorting to
workarounds. Message insertion for outgoing messages, in
'erc-display-msg', remains as before. In rare cases, these changes
may mean third-party code needs tweaking, for example, requiring the
use of 'insert-before-markers' instead of 'insert'. As always, users
feeling unduly inconvenienced by these changes are encouraged to voice
their concerns on the bug list.
Prefer erc-target to erc-default-target * etc/ERC-NEWS: Mention `erc-target' and new `erc-server-buffer-p' alias. * lisp/erc/erc-backend.el (erc-process-sentinel): Set `joined-p' slot of `erc--target-channel' object to nil when applicable. (erc-server-JOIN): Mark `erc--target-channel' object as being joined. * lisp/erc/erc-common.el (erc--target-channel): Add `joined-p' slot. Use hyphenated name so accessor function's name ends in "joined-p" rather than "joinedp". Note that this will always be nil when disconnected. (erc--target): Relocate here from erc.el. (erc-target): New public API function to return the current buffer's target as a string, even in channels that have been unjoined. * lisp/erc/erc-networks.el (erc--default-target): Remove forward declaration. (erc-networks--id-reload): Use `erc-target' instead of `erc--default-target' as predicate for visiting target buffers. * lisp/erc/erc.el (erc-remove-channel-users): Set channel "joinedness" to nil in `erc--target-channel' object, when applicable.

*** Introducing new ways to detect ERC buffer types.
The old standby 'erc-default-target' has served ERC well for over two
decades. But a lesser known gotcha affecting its use has always
haunted an unlucky few, that is, the function has always returned
non-nil in "unjoined" channel buffers (those that the client has
parted with or been kicked from). While perhaps not itself a major
footgun, recessive pitfalls rooted in this subtlety continue to affect
dependent functions, like 'erc-get-buffer'.
To discourage misuse of 'erc-default-target', ERC 5.6 offers an
alternative in the function 'erc-target', which is identical to the
former except for its disregard for "joinedness." As a related bonus,
the dependent function 'erc-server-buffer-p' is being rebranded as
'erc-server-or-unjoined-channel-buffer-p'. Unfortunately, this
release lacks a similar solution for detecting "joinedness" directly,
but users can turn to 'xor'-ing 'erc-default-target' and 'erc-target'
as a makeshift kludge.
*** Miscellaneous changes
Simplify erc-button movement commands * etc/ERC-NEWS: Mention TAB being bound to new command `erc-tab' and `erc-previous-button' now stopping at the start of buttons. * lisp/erc/erc-button.el (erc-button-mode, erc-button-enable, erc-button-disable): Add and remove `erc-button-next' to `erc--tab-functions' hook, which is tantamount to binding the command in the read-only area of an ERC buffer. (erc-button-next-function): Deprecate and remove from client code path because this module doesn't concern itself with prompt input and thus no longer needs to conform to the `completion-at-point-functions' interface. (erc-button--prev-next-predicate-functions): New variable, a hook to determine whether to continue searching for a button. Other modules should utilize this as needed. (erc-button--end-of-button-p): Add function to serve as default value for `erc-button--continue-predicate'. (erc--button-next): Add generalized button-movement function. (erc-button-next, erc-button-previous): Make `erc-button-previous' behave more predictably by having it land at the beginning of buttons. And remove roundabout appeal to HOF in `erc-button-next'. (erc-button-previous-of-nick): New command to jump to previous appearance of nick at point. * lisp/erc/erc-fill.el (erc-fill-wrap, erc-fill-wrap-enable, erc-fill-wrap-disable): Add and remove merge-related hookee from `erc-button--prev-next-predicate-functions'. (erc-fill--wrap-merged-button-p): New function to detect redundant speakers. * lisp/erc/erc.el (erc-complete-functions): Quote TAB in doc string. (erc-mode-map): Bind `erc-tab' to TAB. (erc--tab-functions, erc-tab): Add new command and hook to serve as unified dispatch for TAB-related operations. It calls `c-a-p' in the input area and defers to module code in the read-only message area. * test/lisp/erc/erc-button-tests.el: New file. * test/lisp/erc/erc-fill-tests.el (erc-fill-tests--wrap-populate): Run finalizer for transient keymap timer. * test/lisp/erc/erc-tests.el (erc-button--display-error-notice-with-keys): Move to new dedicated test file for erc-button and fix expected behavior of `erc-button-previous'. (Bug#62834)
2023-04-11 00:58:05 +00:00
Two helper macros from GNU ELPA's Compat library are now available to
third-party modules as 'erc-compat-call' and 'erc-compat-function'.
In 'erc-button-alist', 'Info-goto-node' has been supplanted by plain
old 'info', and the "<URL:...>" entry has been removed because it was
more or less redundant. In all ERC buffers, the "<TAB>" key is now
bound to a new command, 'erc-tab', that calls 'completion-at-point'
inside the input area and otherwise dispatches module-specific
commands, like 'erc-button-next'.
* Changes in ERC 5.5
** Smarter buffer naming for withstanding collisions.
ERC buffers now remain tied to their logical network contexts, even
while offline. These associations can survive regional server changes
and the intercession of proxies. As has long been practiced in other
areas of Emacs, "uniquified" buffer renaming prevents collisions
between buffers of different contexts. ERC's approach prioritizes
predictability over economy, favoring fully qualified suffixes without
elided or omitted components. Potential avenues for confusion remain
but will die out with the adoption of emerging protocol extensions.
** Option 'erc-rename-buffers' deprecated.
The promises made by its old "on" state are now fully realized and
enabled permanently by default. Its old behavior when disabled has
been preserved and will remain available (with warnings) for years to
come.
** Option 'erc-reuse-buffers' deprecated.
This ancient option has been a constant source of confusion, as
exhibited most recently when its "disabled" meaning was partially
inverted. Introduced in ERC 5.4 (Emacs 28.1), this regression saw
existing channel buffers transparently reassociated instead of created
anew. The pre-5.4 "disabled" behavior has been restored and will
remain accessible for the foreseeable future, warts and all (e.g.,
with its often superfluous "/DIALED-HOST" suffixing always present).
** The 'networks' module is now quasi-required.
The 'networks' module is now all but required for everyday interactive
use. A default member of 'erc-modules' since ERC 5.3, 'networks' has
grown increasingly integral to core client operations over the years.
From now on, only the most essential operations will be officially
supported in its absence, and users will see a warning upon invoking
an entry point, like 'erc-tls', when that's the case.
On a related note, the function 'erc-network' now always returns
non-nil in buffers created by a successfully established IRC
connection, even after that connection has been closed. This was done
to aid the overall effort to improve buffer association.

** Tighter auth-source integration.
The days of hit-and-miss auth-source queries are hopefully behind us.
With the overhaul of the services module temporarily shelved and the
transition to SASL-based authentication still underway, users may feel
left in the lurch to endure yet another release cycle of backtick
hell. For some, auth-source may provide a workaround in the form of

2022-11-30 06:53:44 +00:00
A new module, 'erc-sasl', now ships with ERC. See Info node "(erc)
SASL" in the manual for details.
** Username argument for entry-point commands.
Commands 'erc' and 'erc-tls' now accept a ':user' keyword argument,
which, when present, becomes the first argument passed to the "USER"
IRC command. The traditional way of setting this globally, via
'erc-email-userid', is still honored.
** Changes to display options for new ERC buffers.
The default value for the option 'erc-join-buffer', which determines
how new buffers are displayed, has been changed to 'bury' for security
reasons. Although the old value of 'buffer' is still accessible,
along with its original behavior, users wanting a safer alternative
can now opt for an improved 'window-noselect' instead. It still
offers the same pronounced visual cue when connecting and joining but
now avoids any hijacking of the active window as well.
Beyond this, additional flexibility is now available for controlling
the behavior of newly created target buffers during reconnection.
See the option 'erc-reconnect-display' for more.
** Improved handling of multiline prompt input.
This means better detection and handling of intervening and trailing
blanks when 'erc-send-whitespace-lines' is active. New options have
also been added for warning when input spans multiple lines. Although
off by default, new users are encouraged to enable them. See options
'erc-inhibit-multiline-input' and 'erc-ask-about-multiline-input'.
** URL handling has improved.
Clicking on 'irc://' and 'ircs://' links elsewhere in Emacs now does
the right thing most of the time. However, for security reasons,
users are now prompted to confirm connection parameters prior to lift

off. See the new '(erc) Integrations' section in the Info manual for
details.
** ERC's major-mode hook now runs slightly later.
The function 'erc-open' now delays running 'erc-mode-hook' until ERC's
prompt and its bounding markers and many essential local variables
have been initialized. Those essentials include the familiar
'erc-default-recipients', 'erc-server-users', and 'erc-network', as
well as the various "session" variables, like 'erc-session-connector'.
ERC activates "local modules" immediately afterward, just before
running 'erc-connect-pre-hook', which is still useful for gaining a
full accounting of what's been set.
In similar news, 'erc-open' no longer calls 'erc-update-modules'.
However, it still activates modules in a similar fashion, meaning,
among other things, global-module setup still occurs before major-mode
activation (something that's here to stay for compatibility reasons).
** Miscellaneous behavioral changes impacting the user experience.
A bug has been fixed that saw prompts being mangled, doubled, or
erased in server buffers upon disconnection. Instead, input prompts
now collapse into an alternate form designated by the option
'erc-prompt-hidden'. Behavior differs for query and channel buffers
but can be fine-tuned via the repurposed, formerly abandoned option
'erc-hide-prompt'.
Another fix-turned-feature involves certain commands provided by the
'erc-match' module, such as 'erc-add-keyword', 'erc-add-pal', and
others, which now optionally offer to 'regexp-quote' the current
input. The old behavior, if desired, can still be had via the new
option 'erc-match-quote-when-adding'.
In 5.4, support for using network symbols as keys was added for
'erc-autojoin-channels-alist'. This has been extended to include
explicit symbols passed to 'erc-tls' and 'erc' as so-called
network-context identifiers via a new ':id' keyword. The latter
carries wider significance beyond autojoin and can be used for
unequivocally identifying a connection in a human-readable way.
A number of UX-centric bug fixes accompany this release. For example,
spaces are now possible in server passwords, and users of the Soju
bouncer should no longer see outgoing messages pile up during periods
of heavy traffic. See the Emacs change log for the full complement.
Support local ERC modules in erc-mode buffers * doc/misc/erc.texi: Mention local modules in Modules chapter. * etc/ERC-NEWS: Mention changes to `erc-update-modules'. * lisp/erc/erc.el (erc-migrate-modules): Add some missing mappings. (erc-modules): When a user removes a module, disable it and kill its local variable in all ERC buffers. (erc-update-modules): Move body of `erc-update-modules' to new internal function. (erc--update-modules): Add new function, a renamed and slightly modified version of `erc-update-modules'. Specifically, change return value from nil to a list of minor-mode commands for local modules. Use `custom-variable-p' to detect flavor. (erc--merge-local-modes): Add helper for finding local modules already active as minor modes in an ERC buffer. (erc-open): Replace `erc-update-modules' with `erc--update-modules'. Defer enabling of local modules via `erc--update-modules' until after buffer is initialized with other local vars. Also defer major-mode hooks so they can detect things like whether the buffer is a server or target buffer. Also ensure local module setup code can detect when `erc-open' was called with a non-nil `erc--server-reconnecting'. * lisp/erc/erc-common.el (erc--module-name-migrations, erc--features-to-modules, erc--modules-to-features): Add alists of old-to-new module names to support module-name migrations. (erc--assemble-toggle): Add new helper for constructing mode toggles, like `erc-sasl-enable'. (define-erc-modules): Defer to `erc--assemble-toggle' to create toggle commands. (erc--normalize-module-symbol): Add helper for `erc-migrate-modules'. * 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.)
2021-07-12 10:44:28 +00:00
** Miscellaneous behavioral changes in the library API.
A number of core macros and other definitions have been moved to a new
file called erc-common.el. This was done to help mitigate various
complications arising from the mutual dependency between 'erc' and
'erc-backend'.
Also on the maintainability front, ERC now relies on the Compat
library from GNU ELPA to supply forward compatibility shims for users
running older versions of Emacs. The required Compat version resides
atop ERC's main library file, in the 'Package-Requires' header.
Third-party modules should benefit automatically from its adoption.
In an effort to help further tame ERC's complexity, the variable
'erc-default-recipients' is now expected to hold but a single target.
As a consequence, functions like 'erc-add-default-channel' that
imagine an alternate, aspirational model of buffer-target relations
have been deprecated. For specifics, see entries in Emacs'
ChangeLog.4 from around June 30, 2022.
A number of less consequential deprecations also debut in this
release. For example, the function 'erc-auto-query' was deemed too
difficult to understand, behavior wise, and has thus been stricken
from the client code path with no public replacement. Although likely
uncontroversial, such changes may still spell disruption for some. If
you find yourself among them and in need of explanations, please see
related entries in the change log and discussions on the bug tracker.
Although this release is light on API features, some groundwork has
been laid for what may become a new breed of ERC module, namely,
"connection-local" (or simply "local") modules. This marks a small
but crucial step forward toward a more flexible and granular revamping
of ERC's long touted extensibility. See the Info node "(erc) Local
Modules" for details.
Lastly, a few internal variables have been introduced that could just
as well have been made public, possibly as user options. Likewise for
some internal functions. As always, users needing such functionality
officially exposed are encouraged to write to emacs-erc@gnu.org.
* Changes in ERC 5.4.1
** No user-visible changes since ERC 5.4, but a few tweaks in some ERC
file headers and the ERC manual in order to successfully build ERC for
GNU ELPA. (See below for the news item of ERC now being distributed
on GNU ELPA in addition to its continued inclusion in GNU Emacs core.)
* Changes in ERC 5.4
** Starting with Emacs 28.1 and ERC 5.4, ERC NEWS are added here again.
After ERC 5.3, since November 2012, ERC's NEWS items were added in the
main Emacs NEWS file, and users were referred to there. Now, starting
with Emacs 28.1 and ERC 5.4, which mark ERC's release to GNU ELPA, ERC
NEWS have been moved to this file again, so that we can include a NEWS
file consisting only of ERC changes in ERC's package on GNU ELPA.
The NEWS entries for ERC changes in Emacs 28.1 have been moved from
the main Emacs NEWS file to here. For ERC NEWS entries corresponding
to Emacs versions before 28, to avoid modifying the NEWS file for all
of those releases, the ERC NEWS entries have only been copied below,
and the NEWS.* files were left intact.
** ERC is now available on GNU ELPA.
Starting with ERC 5.4, in addition to being distributed with GNU Emacs
itself, ERC is also included in GNU ELPA, allowing users to enjoy the
improvements of newer ERC versions on older Emacs versions as well.
ERC's package page on GNU ELPA: https://elpa.gnu.org/packages/erc.html
** New option 'erc-rename-buffers'.
** New faces 'erc-my-nick-prefix-face' and 'erc-nick-prefix-face'.
** 'erc-format-@nick' displays all user modes instead of only op and voice.
** The display of irc commands in the current buffer has been disabled.
** 'erc-version' now follows the Emacs version.
** ERC can now hide message types by network or channel.
'erc-hide-list' will hide all messages of the specified type, while
'erc-network-hide-list' and 'erc-channel-hide-list' will only hide the
specified message types for the respective specified targets.
** Reconnection is now asynchronous.
** Nick completion is now case-insensitive again after inadvertently
being made case-sensitive in Emacs 24.2.
** New variable 'erc-default-port-tls' used to connect to TLS IRC
servers.
** New hook 'erc-insert-done-hook'.
This hook is called after strings have been inserted into the buffer,
and is free to alter point and window configurations, as it's not
called from inside a 'save-excursion', as opposed to 'erc-insert-post-hook'.
** 'erc-button-google-url' has been renamed to 'erc-button-search-url'
and its value has been changed to Duck Duck Go.
** 'erc-send-pre-hook' and 'erc-send-this' have been obsoleted.
The user option to use instead to alter text to be sent is now
'erc-pre-send-functions'.
** Improve matching/highlighting of nicknames.
Open and close parenthesis and apostrophe are not considered valid
nick characters anymore, matching the given grammar in RFC 2812
section 2.3.1. This enables correct matching and highlighting of
nicks when they are surrounded by parentheses, like "(nick)", and when
adjacent to an apostrophe, like "nick's".
** Set 'erc-button-url-regexp' to 'browse-url-button-regexp'
which better handles surrounding pair of parentheses.
** New function 'erc-switch-to-buffer-other-window'
which is like 'erc-switch-to-buffer', but opens the buffer in another
window.
** New function 'erc-track-switch-buffer-other-window'
which is like 'erc-track-switch-buffer', but opens the buffer in
another window.
** NickServ passwords can now be retrieved from auth-source.
The 'erc-use-auth-source-for-nickserv-password' user option enables
querying auth-source for NickServ passwords. To enable this, add the
following to your init file:
(setq erc-use-auth-source-for-nickserv-password t)
** NickServ identification now prompts for password last.
When 'erc-prompt-for-nickserv-password' is non-nil, the user used to
be unconditionally prompted interactively for a password, regardless
of the value of 'erc-nickserv-passwords', which was effectively
ignored (same for the new
'erc-use-auth-source-for-nickserv-password'). This limitation is now
lifted, and the user is interactively prompted last, after the other
identification methods have run.
** The '/ignore' command will now ask for a timeout to stop ignoring the user.
Allowed inputs are seconds or ISO8601-like periods like "1h" or "4h30m".
** ERC now recognizes 'C-]' for italic text.
Italic text is displayed in the new 'erc-italic-face'.
** erc-match.el now supports 'message' highlight type (not including the nick).
The 'erc-current-nick-highlight-type', 'erc-pal-highlight-type',
'erc-fool-highlight-type', 'erc-keyword-highlight-type', and
'erc-dangerous-host-highlight-type' user options now support a
'message' type for highlighting the entire message but not the
sender's nick.
** erc-status-sidebar.el is now part of ERC.
The 'erc-status-sidebar' package which provides a HexChat-like
activity overview sidebar for joined IRC channels is now part of ERC.
** erc-tls now supports specifying a TLS client certificate.
The 'erc-tls' function has been updated to allow specifying a TLS
client certificate for authentication, as an alternative to NickServ
password-based authentication. This is referred to as "CertFP" (short
for Certificate Fingerprint) by several IRC networks. See the Info
node "(erc) Connecting" in the ERC manual for more details and
examples on how to specify and use TLS client certificates with
'erc-tls'.
** Update IRC-related references to point to Libera.Chat.
The Free Software Foundation and the GNU Project have moved their
official IRC channels from the Freenode network to Libera.Chat.
For the original announcement and the follow-up update, including
more details, see:
https://lists.gnu.org/archive/html/info-gnu/2021-06/msg00005.html
https://lists.gnu.org/archive/html/info-gnu/2021-06/msg00007.html
Given the relocation of GNU and FSF's official IRC channels, as well
as #emacs and various other Emacs-themed channels (see the link below)
to Libera.Chat, IRC-related references in the Emacs repository have
now been updated to point to Libera.Chat.
https://lists.gnu.org/archive/html/info-gnu-emacs/2021-06/msg00000.html
** Add 'erc-track-select-mode-line-face' (obsoletes 'erc-track-find-face').
The 'erc-track-find-face' function of the erc-track module has been
declared obsolete and rewritten as 'erc-track-select-mode-line-face',
with different expected arguments (the current and old faces are now
separated) and clearer documentation.
** Add '/opme' and '/deopme' convenience commands.
The new '/opme' convenience command asks ChanServ to set the operator
status for the current nick in the current channel, and '/deopme'
unsets it.
** Add '/wii' convenience command for whois with idle time.
The new '/wii' convenience command calls the '/whois' command with the
given nick as both arguments, which is useful for displaying the whois
information for the nick along with idle time, even if the nick is on
a different server than the one the current user is connected to.
Using the given nick itself instead of the server it is connected to
is not standardized, but is widely supported across IRC networks.
2012-11-08 04:19:38 +00:00
** Add 'erc-bug' command for reporting ERC bugs.
The new 'erc-bug' command prompts for a subject, and passes it on to
'report-emacs-bug' along with the current ERC version, and adds the
ERC mailing list in Cc.
2007-09-08 03:07:09 +00:00
* Changes in ERC 5.3
** New function `erc-tls' is to be used for connecting to a server via TLS.
It requires the tls.el library.
** The function `erc-ssl' will now always use ssl.el, even in the version
of ERC that comes with Emacs.
2007-09-08 03:07:09 +00:00
2007-10-29 01:00:33 +00:00
** Type `C-u' before `C-c C-j' to prompt for a channel key
`erc-join-channel' now accepts a prefix-argument to prompt for the key
when channels are protected by keywords.
** ERC will now automatically determine which nick prefixes are valid
when joining a server.
** Figure out which directory contains startup files when looking for
.erc.el. For Emacs this is usually ~/.emacs.d, and for XEmacs this is
usually ~/.xemacs.
** Fix bug with view-mode when running erc-toggle-debug-irc-protocol.
** Permit several commands to be run even when the server connection is dead.
This includes /CLEAR, /COUNTRY, /HELP, /LASTLOG, /QUIT, /GQUIT,
/RECONNECT, /SERVER, and /SET.
** Make /RECONNECT work better when the server connection is dead.
Also, handle case where the server buffer has been killed.
** Better handle interaction with /RECONNECT and indefinite reconnect
attempts. Display message which tells the user that they can stop the
reconnect attempts by killing the server buffer.
** New option `erc-reuse-frames' determines whether new frames are always
created. It defaults to not creating a new frame for an ERC buffer if
there is already a window displaying it. This only has an effect when
the `erc-join-buffer' option is set to 'frame.
** New command /ME'S handles the case where someone types "/me's" in an
ERC buffer. It concatenates the text " 's" to the beginning of the
input and then sends the result like a normal /ME command.
** Fix bug where some messages were being sent to the server too soon.
In the past, this may have resulted in strange problems like seeing
the connection attempt stall, which may have especially affected
spotty or traffic-shaped connections.
** Handle 307 (nick has identified) responses from the server.
** Display a less-confusing message if the connection attempt fails.
** On a tty, make sure that notices are displayed in blue rather than pink.
** By default, open query buffers that are initiated by others in a new
unselected window. This may be changed by customizing the
`erc-auto-query' option. This should make ERC more friendly to new
users.
** New option `erc-query-display' indicates how to display a query buffer
that is made using the /QUERY command. The default is to display the
query in a new selected window.
** By default, display network name rather than server name in the modeline.
This should ERC use less space in the modeline. To get the old
behavior back, set `erc-mode-line-format' to "%s %a".
** New option `erc-remove-parsed-property' determines whether to remove
the 'erc-parsed property. This should save some memory in channels
with large amounts of text on screen. It is enabled by default.
** Modules newly enabled by default
*** move-to-prompt: Move to the prompt when typing text.
*** networks: Provide data about IRC networks.
** New formatting variables allowed in `erc-format-network':
*** `%N': the name of the network.
*** `%S': much like %s, but let the network name trump the server name.
** Compatibility with old releases
*** In `erc-server-coding-system' and `erc-coding-system-for-target', pass
the `target' argument as the first and only argument to the function
named by these options.
*** In `erc-track-faces-priority-list', permit list entries to be lists of
faces. This can be used to differentiate between, for example,
buttons in default text and buttons in notices.
*** The `erc-assert' function has been removed in favor of using `assert'
from cl-macs.el.
*** If your application uses the 'erc-parsed text property outside of
the insert hooks, you will need to set `erc-remove-parsed-property'
to nil.
2007-09-08 03:07:09 +00:00
** Changes and additions to modules
*** BBDB (erc-bbdb.el)
**** Work around bug in XEmacs 21.4 that causes an error to be thrown when
the first argument to `run-at-time' is nil.
*** Button (erc-button.el)
**** Recognize parentheses that are part of URLs.
**** When in a channel, only buttonize nicks from that channel.
*** DCC support (erc-dcc.el)
**** Turn this into the "dcc" module for ERC, so that it can be more
easily enabled.
**** New option `erc-dcc-listen-host' determines which IP address to listen
on for outside connection attempts.
**** New option `erc-dcc-public-host' determines which IP address to advertise
when sending a file. This is useful for people who are on a local
subnet. Together, these two options replace the `erc-dcc-host'
option.
**** New option `erc-dcc-receive-cache' indicates how much of a received
file to store in an Emacs buffer before flushing it to disk. The
default is 0.5 MB.
**** Save only parts of received files in buffers, writing repeatedly to
disk after we get at least `erc-dcc-receive-cache' bytes. This allows
users to receive very large files without running out of memory.
**** Rename `erc-verbose-dcc' option to `erc-dcc-verbose' and also
default it to nil.
**** Fix edge case in erc-dcc-send-sentinel.
**** If client confirms too much, then display byte count and kill the
file buffer.
*** Goodies (erc-goodies.el)
**** New module move-to-prompt causes the point to be moved to the prompt
if a user tries to type elsewhere in the buffer, and then inserts
their keystrokes after the prompt. It is enabled by default.
**** New module keep-place keeps your place in unvisited ERC buffers
when new messages arrive.
**** Enable scroll-to-bottom in all ERC buffers when the module is enabled,
rather than having the user do it manually.
**** Fix bug with buffer ordering and scroll-to-bottom module.
**** In the unmorse module, handle the morse code style that has "/ " at
the end of every letter.
*** Identd (erc-identd.el)
**** Fix bad behavior when closing the identd process.
*** Channel lists (erc-list.el)
**** Replace the old module with a rewritten one, so that we can include
it with Emacs. The old version of erc-list.el has been renamed to
erc-list-old.el, and is available as the list-old module.
The new version does not yet have support for XEmacs.
**** Don't display lots of output in the server buffer when running /LIST.
*** Logging (erc-log.el)
**** Permit the `erc-log-channels-directory' option to be set to a function
name. This makes it easier to write custom functions that determine
where log files should be placed.
**** New option `erc-log-filter-function' specifies the function to call
for filtering text before writing it to a log file. By default, no
filtering is performed.
*** Networks (erc-networks.el)
**** Turn this into the "networks" module for ERC, so that it can be more
easily enabled. Enable it by default.
**** Add support for Rizon.
*** Internet services / Nickserv (erc-services.el)
**** New hook option `erc-nickserv-identified-hook' is run after NickServ
acknowledges a successful identification.
**** Add support for the GRnet and Rizon networks.
*** Timestamps (erc-stamp.el)
**** By default, place timestamps on both the left and the right.
The left timestamps appear once a day, and the right timestamps appear
once a minute when new messages arrive. To change this, customize the
`erc-insert-timestamp-function' and
`erc-insert-away-timestamp-function' options.
2007-09-08 03:07:09 +00:00
*** Channel tracking (erc-track.el)
**** If `erc-track-position-in-mode-line' is set to nil, the tracking
information won't be shown in the mode line, which is a change from
the previous behavior of showing it "After all other information".
If this variable is set to t, then the information will be added to
the very end of the mode line.
**** New option `erc-track-remove-disconnected-buffers' controls whether
buffers associated with a server that is disconnected should be
removed from the modified buffers list. The default is to keep them
in the list.
**** New hook option `erc-track-list-changed-hook' is run whenever the
contents of the modified channels list changes. It is useful for
people who use a separate mechanism to provide notification of channel
activity.
**** The `erc-track-switch-direction' option now can be set to the value
'importance. If set to this value, ERC will switch to channels in
order of importance, which is determined by the position of the
channel's face in `erc-track-faces-priority-list'.
**** Activate erc-track-minor-mode earlier in the connection process.
**** Don't track buttons in notices.
**** Get a rough idea for which channels are currently active by
switching between several normal conversation faces in the modeline.
This behavior can be modified by changing the new
`erc-track-faces-normal-list' option.
**** Ignore display of who set the default channel topic and listing of
users on the current channel. Customize the `erc-track-exclude-types'
option to indicate the types of messages to exclude. These two
message types are "333" and "353", respectively.
*** Support for acting as an XDCC file-server (erc-xdcc.el)
**** Turn this into the "xdcc" module for ERC, so that it can be more
easily enabled.
2007-09-08 03:07:09 +00:00
* Changes in ERC 5.2
** M-x erc RET now starts ERC.
`erc-select' has been changed to `erc'. `erc-select' still remains as
an alias of `erc'. Likewise, `erc-select-ssl' has been renamed to
`erc-ssl' with `erc-select-ssl' as its alias. The function that was
known as `erc' is now `erc-open'.
** Open query buffers by default when private messages are received.
The default value of `erc-auto-query' has been changed to 'bury.
** New command: /RECONNECT
This command tries to reconnect to the current IRC server exactly
once. It does not work in server buffers (throws an error before the
command is run), but works in query and channel buffers.
** In MS-DOS environments, look for _ercrc.el rather than .ercrc.el.
** Fix buggy interaction with multi-tty Emacs.
** After running /QUIT, make sure that the IRC process is killed within
4 seconds. Freenode, in particular, needs this at times.
** If the IRC process has not responded to our PINGs within a certain
time, kill it and restart the connection. See
`erc-server-auto-reconnect', `erc-server-reconnect-attempts',
`erc-server-reconnect-timeout', `erc-server-send-ping-interval', and
`erc-server-send-ping-timeout' to fine-tune ERC's behavior.
** Avoid getting into an infinite connection loop.
Previously, this could happen if your nick was banned, you were using
Tor, incorrect information was entered, or the connection was bad.
** Make ban messages less confusing.
** Restore the point correctly when reconnecting to an IRC server.
** Make /IGNORE and /UNIGNORE prompt to determine whether their
argument is a user or a regexp. This results in less-confusing
behavior when trying to ignore someone who has a bracket in their
nick.
** Make the default port "6667" rather than "ircd", because some
operating systems don't know what port "ircd" maps to.
** Fix several bugs in erc-iswitchb (C-c C-b).
** Clean up internal documentation.
Special thanks go to Juanma Barranquero for the thorough vetting of
ERC's internal documentation.
** Display a more informative message when a module is not found.
** Fix a bug where paths were being colored like IRC commands.
** In the customize interface for `erc-modules', add the name of the module.
This makes it easier to find modules by name.
** erc-server-send-ping-interval: Change to use a default of 30 seconds.
** Some files which are included with the release of ERC 5.2 will not
appear in the version of ERC that is bundled with Emacs 22. These
extras files may be found at:
o https://ftp.gnu.org/gnu/erc/erc-5.2-extras.tar.gz, or
o https://ftp.gnu.org/gnu/erc/erc-5.2-extras.zip.
** Renamed files
Several files were renamed so as to make them distinct to users of the
MS-DOS operating system.
o erc-autojoin.el -> erc-join.el
o erc-complete.el -> erc-hecomplete.el
o erc-nickserv.el -> erc-services.el
o ChangeLog.NNNN -> ChangeLog.NN
** Header line changes
*** Remove "[IRC]" from the header line.
*** Add the %l format character to `erc-header-line-format',
*** Document how to remove the header line.
Namely: (setq erc-header-line-format nil).
** New options
*** erc-server-reconnect-attempts: Determines the number of
reconnection attempts that ERC will make per server.
*** erc-server-reconnect-timeout: Determines the amount of time,
in seconds, that ERC will wait between successive reconnect attempts.
*** erc-server-send-ping-timeout: Determines when to consider a connection
stalled and restart it. The default is after 120 seconds.
*** erc-system-name: Determines the system name to use when logging in.
The default is to figure this out by calling `system-name'.
** New face: `erc-my-nick-face'
This helps make it easier to distinguish messages sent by yourself
from messages sent by other users when the value of the variable
`erc-show-my-nick' is non-nil.
** Namespace changes
*** New macro: `erc-with-server-buffer'
Switches to the current ERC server buffer and runs some code. If no
server buffer is available, return nil. This is a useful way to
access variables in the server buffer.
*** New function: `erc-open-server-buffer-p'
Returns non-nil if the given buffer is an ERC server buffer that has
an open IRC process.
*** New function: `erc-format-lag-time'
Returns the estimated lag time to server, `erc-server-lag'.
*** Renamed items
o `erc-server-setup-periodical-server-ping' is now
`erc-server-setup-periodical-ping'
o `erc-away-p' is now `erc-away-time'
** Changes to the ERC manual
*** New section: Sample Session.
Describes a sample ERC session for connecting to the #emacs channel on
Freenode. Also mention the #erc channel.
*** New section: Special Features.
Describes some of the special features of ERC.
*** Getting Started: Mention ~/.emacs.d/.ercrc.el and the Customize
interface.
*** Development: Mention ErcDevelopment page on emacswiki.org.
*** Tips and Tricks: Remove empty section for now.
*** Options: Mention how to see available ERC options.
*** Sample Configuration: Add an example of how to configure ERC.
** New modules
*** Autoaway (erc-autoaway.el)
**** Make this much more reliable.
**** Avoid duplicate messages when coming back from being away.
**** Fix bug where autoaway was enabled just by loading the file.
*** BBDB (erc-bbdb.el)
**** Display information on how to cancel merging of info or how to
create a new John Doe record.
**** Make it so that information from /whois continues to come in, even
while prompting for a record to merge.
**** Make hitting C-g correctly abort merging the record.
*** Capab identify (erc-capab.el)
Mark users who haven't identified to NickServ on servers supporting
CAPAB IDENTIFY-MSG.
** Changes and additions to modules
*** Button (erc-button.el)
**** Make <backtab> go to the previous button.
*** Channel tracking (erc-track.el)
**** Use mouse-face and help-echo for channel names in the mode-line.
This helps people using a mouse know that they are buttons and can be
clicked on.
**** Fix issue where C-c C-SPC could conflict with user-defined keybindings.
This is accomplished by moving these bindings to their own global
minor mode. Now the default is to check whether the user has bound
something to C-c C-SPC or C-c C-@. If they have, prompt them about
whether to really override that binding. This also has the effect of
preventing ERC from clobbering rcirc's keybinding, unless this is
desired. See `erc-track-enable-keybindings' for more details.
**** New option: erc-track-enable-keybindings.
Determine whether or not to enable the C-c C-SPC and C-c C-@
keybindings. The default is to ask whether to do this if a binding to
these keys already exists. It can also be set to t or nil to always
bind or never bind, respectively.
**** Remove `track-when-inactive' module.
See `erc-track-when-inactive' for further details.
**** New option: erc-track-when-inactive.
This option replaces the track-when-inactive module. Set it to
non-nil to track activity even in visible buffers when inactive. The
default is nil.
**** Remove the `track-modified-channels' alias for the `track' module.
*** DCC support (erc-dcc.el)
**** Add Usage section to Commentary.
**** Fix a bug in the server message output.
*** Filling (erc-fill.el)
**** Fix bug involving messages that start with one or more blank lines.
*** Identd (erc-identd.el)
**** New option `erc-identd-port'
Specifies the port to use if none is given as an argument to
`erc-identd-start'. This is placed in the new customization group
`erc-identd'.
**** New function: `erc-identd-quickstart'
Ignores any arguments and calls `erc-identd-start'.
*** Channel lists (erc-list.el)
**** Enable by default, except in the version of ERC bundled with Emacs 22.
*** Logging (erc-log.el)
**** Make sure filenames are safe to use before writing to them.
**** Save all log buffers when exiting Emacs.
**** erc-generate-log-file-name-function: Add option for
`erc-generate-log-file-name-network', which is a new function that
uses the network name rather than the server name when possible.
*** Menu (erc-menu.el)
**** Name the menu "ERC" instead of "IRC" to avoid confusion with rcirc
and other clients.
**** Make this into a proper module and load it by default.
**** Add "Current channel" submenu.
*** Networks (erc-networks.el)
**** Add support for Ars OpenIRC, LinuxChix, and OFTC networks.
**** Escape periods in Konfido.Net and Kewl.Org.
*** Internet services / Nickserv (erc-nickserv.el)
**** Add new 'both method for the `erc-nickserv-identify-mode' option
and make it the default. This tries to do the right thing both when a
known nickserv message exists for an IRC network, and when it does
not.
**** Support nickserv authentication on OFTC, Azzurra, Ars, and QuakeNet.
**** Support authentication on BitlBee.
**** Make source code easier to understand by using accessor functions.
*** Sound support (erc-sound.el)
**** Make this work with both Emacs 21 and Emacs 22.
*** Timestamps (erc-stamp.el)
**** Exclude the newline from the erc-timestamp field.
**** New function: `erc-toggle-timestamps'.
Toggles display of timestamps.
* Changes in ERC 5.1.4
** Make find-function and find-variable work in Emacs 22 for
names that are constructed by `define-erc-module'.
** Fix bug introduced in ERC 5.1.3 that caused messages to go the
wrong buffer.
** Changes and additions to modules
*** Highlighting (erc-match.el)
**** Don't activate view-mode.
*** Logging (erc-log.el)
**** When this module is activated, make sure logging is enabled on
already-opened buffers. Ditto for disabling logging when the module
is deactivated.
**** Fix some errors that occur when exiting Emacs without first
quitting open IRC servers.
* Changes in ERC 5.1.3
** Fix use of /quote command with no initial whitespace.
** Make it possible to customize the colorization of the header line.
The `erc-header-line' face is used to color the header line.
The `erc-header-line-face-method' determines the method to use when
colorizing the header line.
** Add the new function `erc-handle-irc-url', which is a suitable
candidate to use for `url-irc-function'. This permits some
integration of url.el and ERC.
** Fix several errors that occur when server or channel buffers are killed
prematurely.
** Fix toggling of flood control.
** Match the patterns in `erc-encoding-coding-alist' as regexps,
instead of verbatim text. Also, match case-insensitively.
** The /SMV command has been removed, since we no longer have
meaningful module-specific version information.
** Fix a "(stringp nil)" error that can happen when doing /PART.
** Use a better example in the `erc-part-reason-various-alist'
documentation.
** When using `erc-quit-reason-various' and `erc-part-reason-various'
and no matches are found, default to using the ERC version string
rather than "nil".
** Add the `list' and `page' modules to the `erc-modules' customize
interface.
** Changes to the ERC manual
*** Update the list of available modules.
*** Revise information about releases and development.
*** Provide a simpler example in the "Getting Started" chapter.
*** Fully document how to connect to an IRC server in the new
"Connecting" chapter.
** Changes and additions to modules
*** Autoaway (erc-autoaway.el)
**** Rename the `erc-autoaway-use-emacs-idle' option to
`erc-autoaway-idle-method'.
**** Add support for autoaway based on user idle time.
This is now the default.
**** If you set the AWAY status yourself, erc-autoaway will not
interfere by un-setting AWAY prematurely.
**** If you are set away while visiting a non-ERC buffer,
erc-autoaway used to fail in bringing the user back. This is now
fixed.
*** BBDB (erc-bbdb.el)
**** Add new option `erc-bbdb-electric-p', which determines whether
to make the BBDB buffer electric. This defaults to not electric.
*** Button (erc-button.el)
**** Use <backtab> instead of <C-tab> for `erc-button-previous'.
*** Identd (erc-identd.el)
**** Fix a bug that involves starting the identd server.
**** Make this work with Emacs 22.
**** Provide a real ERC module named `identd'.
**** Don't create an extra buffer for the identd process.
*** Channel lists (erc-list.el)
**** Enable by default, except in the version of ERC bundled with Emacs 22.
*** Logging (erc-log.el)
**** By default, don't insert old logs when opening an ERC buffer.
This may be changed by customizing `erc-log-insert-log-on-open'.
**** New option `erc-log-write-after-send' determines whether the
log file will be written to after every sent message. The default is
not to do this.
**** New option `erc-log-write-after-insert' determines whether the
log file will be written to when new text is added to a logged ERC
buffer. The default is not to do this. With this option and the
previous option, logging should no longer slow down ERC as much.
**** Default to saving buffers and queries on quit.
This may be changed by customizing the `erc-save-buffer-on-quit' and
`erc-save-queries-on-quit' options, respectively.
**** Only perform logging when the `logging' module is added to
`erc-modules'. This prevents logging from being activated just by
loading the erc-log.el file, and makes logging act like other ERC
modules.
*** Programmable completion (erc-pcomplete.el)
**** Don't complete the user's current nickname.
* Changes in ERC 5.1.2
** Fix compiler errors in erc-autojoin.el and erc-dcc.el.
** Move to end of prompt when ERC reconnects to a server.
** Changes and additions to modules
*** Spell-checking (erc-spelling.el)
**** Don't spell-check nicks or words that are prefixed with '/'.
**** Remove flyspell properties from words we shouldn't spell-check.
**** Fix an issue that caused the ispell process to reload every time
we switch to an ERC buffer.
*** Timestamps (erc-stamp.el)
**** Fix an inconsistency in calculating width of right timestamps.
**** Rename option `erc-timestamp-right-align-by-pixel' to
`erc-timestamp-use-align-to'. This controls whether to use the more
fail-proof method of aligning right timestamps, as mentioned below.
**** Fix a right timestamp spacing problem that used to occur when
erc-stamp.el was byte-compiled. Now that this is fixed, it is safe to
use the method that aligns right timestamps perfectly in Emacs22 with
X. If the current version of Emacs doesn't support this method, use
the simpler method, which is prone to alignment issues for math
symbols and other variable-width text.
A side effect of using this new method is that there will only be one
space before a right timestamp in any saved logs. If this is
unacceptable, set `erc-timestamp-use-align-to' to nil.
* Changes in ERC 5.1.1
** Fix a requirement on cl.el.
** Use tls.el for SSL connections, rather than ssl.el.
** Changes and additions to modules
*** ibuffer integration (erc-ibuffer.el)
**** Update this to work with the version of ibuffer.el that comes with
recent Emacs variants.
*** Old completion (erc-complete.el)
**** Fix a few errors.
*** Speedbar (erc-speedbar.el)
**** Make this work with the version of speedbar.el that comes with
recent Emacs variants.
*** Timestamps (erc-stamp.el)
**** By default, use a more failsafe method of displaying right timestamps.
To get right timestamps to align perfectly in Emacs22 using X, set the
new `erc-timestamp-right-align-by-pixel' option to non-nil.
*** Viper compatibility (erc-viper.el)
**** Since most of these changes are now merged into Emacs22, detect
whether we need these changes and install them only if necessary.
* Changes in ERC 5.1
** Improve XEmacs compatibility.
** Namespace changes
*** Now ERC doesn't use global variable space.
Renamed all variables that didn't start with "erc-".
o `away' is now `erc-away'

o `quitting' is now `erc-server-quitting'
*** Remove the `with-erc-channel-buffer' function.
** Bugfixes
*** Don't inadvertently destroy face properties.
*** Load erc scripts in a safer way.
*** Don't insert a timestamp if text at point is invisible.
*** Don't hide messages from those in `erc-fools' by default.
Color their nicks instead.
*** Use a more foolproof method of encoding and decoding strings
before sending to a channel.

o `erc-process' is now `erc-server-process'
o `erc-ping-handler' is now `erc-server-send-ping-handler'
o `erc-ping-interval' is now `erc-server-send-ping-interval'
*** Renamed some functions

`erc-server-setup-periodical-server-ping'
o `erc-split-command is now `erc-split-line'
*** New options
o erc-server-flood-margin, erc-server-flood-penalty: New options
that allow tweaking of flood control.
o erc-split-line-length: The maximum line length of a single
message.
*** New variables
o erc-server-flood-last-message, erc-server-flood-queue,
erc-server-flood-timer: Flood control.
o erc-server-processing-p: Indicate when we're currently processing
a message.
*** Remove some options
o `erc-flood-limit'
o `erc-flood-limit2'
** New customization group `erc-server' for dealing with IRC servers.
** ERC can now be installed by doing `make install' from the command line.
** ERC now has a manual in erc.texi.
Type `make doc' to generate HTML and Info versions of it.
** ERC no longer depends on cl.el.
Only the macros in cl-macs.el are used.
** Fix an edge case when quitting as new messages come in.
** Make flood protection toggle-able as on/off, removing the 'strict option.
** If possible, re-use channel buffers when reconnecting to a server.
** Text in ERC buffers is now read-only by default.
2011-11-15 07:55:13 +00:00
To get the previous behavior,
** Changes and additions to modules
*** Auto-join (erc-autojoin.el)
**** Recognize the Azzurra server.
*** BBDB (erc-bbdb.el)
**** When the user types /WHOIS, ask for a record to merge to.
**** Store the displayed name of a BitlBee contact.
The new `erc-bbdb-bitlbee-name-field' option specifies the field to use
to store this information.
**** Don't prompt for a name on /JOIN or /NICK.
*** Button (erc-button.el)
**** Fix customization of `erc-button-alist'
**** New option `erc-button-nickname-face' determines the face to use
when coloring ERC nicknames.
*** Channel tracking (erc-track.el)
**** Remove channels from the modified channels list if not currently
connected. This should remove residue from the mode line after
quitting ERC.
**** Recognize buttonized text
*** Highlighting (erc-match.el)
**** Highlight current nickname by default.
**** Added the option of beeping when certain matches occur.
Add `erc-beep-on-match' to `erc-text-matched-hook' to enable
beeping. Set the new variable `erc-beep-match-types' which match
types that make beeps.
*** Nicklist (erc-nicklist.el)
**** Fix a couple of errors.
**** Make sure a stray mouse click doesn't trigger an error.
**** Insert icons from the /images directory next to nicks.
This indicates their away status. The location is customizable via
the new `erc-nicklist-icons-directory' option.
If you do not want these icons, set `erc-nicklist-use-icons' to nil.
*** Nickserv identification (erc-nickserv.el)
**** Recognize Azzurra and OFTC networks.
*** Old completion (erc-complete.el)
**** Disable by default.
*** Programmable completion (erc-pcomplete.el)
**** Enable by default.
*** Timestamps (erc-stamp.el)
**** On Emacs22, align right timestamps perfectly, even if variable-width
characters are used. If we aren't using Emacs22, move text farther
away from the right margin when variable-width characters are used.
It is considered better to misalign the stamp by a bit than to go past
the right margin.
**** Enable by default
** New modules
*** Spell-checking (erc-spelling.el)
**** Use flyspell in ERC.
*** Viper compatibility (erc-viper.el)
**** Helps ERC work correctly in viper-mode.
* Changes in ERC 5.0.4
** Fix a problem with undo in channels.
* Changes in ERC 5.0.3
** Fix typo in the `ctcp-request-to' entry of the English catalog.
** Debugging with edegug has been made easier in all of the
erc-with-* and with-erc* macros.
** Non-ASCII character sets should be better supported when sending
and processing messages.
** A load failure with erc-autoaway.el and Emacs21 has been fixed.
** A few XEmacs warnings were fixed.
** Changes and additions to modules
*** Backend (erc-backend.el)
**** Move the check for hidden messages into `erc-display-message'
so there isn't so much replicated code.
**** Add `definition-name' property to constructed symbols so that
`find-function' and `find-variable' will be able to locate them.
**** Make sure logs are inserted info the correct channel buffers.
There was previously an error when using `erc-insert-log-on-open' in
combination with autojoin to multiple channels.
*** Button (erc-button.el)
**** The layering of `erc-button-face' on other faces in ERC buffers
has been improved.
*** Channel tracking (erc-track.el)
**** Use optimal amount of whitespace around modified channels
indicator. Previously, there was an additional unnecessary space.
**** Fix an error that occurred when unchecked buffers existed when
invoking /QUIT.
* Changes in ERC 5.0.2
** If a channel key is required for a certain channel, ERC will prompt
for one if `erc-prompt-for-channel-key' is non-nil.
** ERC doesn't try to reconnect if the network connection is refused
when using `open-network-stream-nowait' as the `erc-connect-function'.
** Messages from multiple servers will not go to the currently active
buffer. The messages from each server will be contained in the most
recently active channel/server buffer that corresponds with the
server.
** Some text messages were cleaned up slightly.
** Button faces should no longer "cover" other faces.
** Made some XEmacs compatibility fixes.
** Nicknames containing a backslash are now correctly highlighted as
current-nick and buttonized as nicks.
** `erc-server-select' doesn't offer networks without servers as a
choice anymore.
** Non-ASCII character support has been improved.
** Changes and additions to modules
*** Menu (erc-menu.el)
**** You can now save logs and truncate buffers from the menu-bar.
* Changes in ERC 5.0.1
** Narrowing in ERC buffers no longer causes formatting errors.
** The BBDB module now loads correctly when customizing `erc-modules'.
** The value of `erc-button-face' is now respected.
** Fixed a bug which caused a read-only error during connection.
** Server buffers are now tracked correctly.
This means that `erc-track-priority-faces-only', `erc-track-exclude',
and `erc-track-exclude-types' now work with server buffers.
* Changes in ERC 5.0
** Channel members are now stored as a hash-table.
`erc-server-users' and `erc-channel-users' are now hash-tables, rather
than alists. This significantly increases performance, especially in
large channels. Each channel member is stored as an `erc-server-user'
struct, with additional information about the channels they are on
stored in an `erc-channel-user' struct. Code using old alist-style
channel members needs to be updated to work with hash-tables.
This new code also removes the need for erc-members.el, which has been
removed.
** The way ERC deals with input from the server has changed.
All server response code is now in a new file, erc-backend.el. There
should be no real user visible changes. There are, however, a few
major changes for implementers, and module writers:
*** The PARSED response that all handlers get called with is
no longer a vector, but an `erc-response' struct.
This means LESS MAGIC NUMBERS in the ERC source code, but a few
changes in how you get at parsed responses.
The sender is accessed via `erc-response.sender'.
The command is accessed via `erc-response.command'.
The arguments to the command (everything after the command and
before the colon) are accessed via `erc-response.command-args'.
This is a /list/ of arguments in the order they appear in the
unparsed response.
The contents of the response is accessed via
`erc-response.contents'.
Should, for some reason, you want to do something with the
/unparsed/ response, you can get it via `erc-response.unparsed'.
*** The `erc-server-hook-list' mechanism is gone.
All server response handlers should be defined with
`define-erc-response-handler'. This defines functions and
corresponding hook variables.
The mapping of server commands to hook variables is no longer
2016-11-04 21:50:09 +00:00
done via `erc-event-to-hook', but through an #'equal hash table,
`erc-server-responses'. In order to find a hook you do:
(erc-get-hook command)
See the docstring of `define-erc-response-handler' for more
information.
*** ALL hook variables have been renamed.
In accordance with recommendations in the Emacs Lisp manual,
the hook variables are no longer called `erc-server-FOO-hook',
but rather `erc-server-FOO-functions'. This is to indicate
that the functions they call take arguments.
All the modules in ERC have been updated to reflect this change,
but external module authors should beware.
** The values of `erc-mode-line-format' and `erc-header-line-format'
are now defined as strings to be formatted using `format-spec'.
`erc-mode-line-format' does not replace the whole mode-line anymore,
only `mode-line-buffer-identification' is set. This way, personal
mode-line configurations are not modified and all key bindings work as
expected. The process status (connecting, closed) is now shown in
`mode-line-process'.
** Customization of ERC variables has been made easier. Variables
have been split into more groups for better organization.
** New variables
o `erc-send-whitespace-lines' - Set this to send lines even if they
are empty.
o `erc-manual-set-nick-on-bad-nick-p' - If the nickname you chose is
already taken or not allowed, your nick is not changed and you can
try again manually if this is non-nil.
o `erc-mode-line-away-status-format' - You can now set what is shown
in the mode-line when you are away.
o `erc-header-line-uses-help-echo-p' - The header-line now uses the
help-echo property. You can set this to nil to disable it.
o `erc-format-query-as-channel-p' - Set this to nil to have messages
in the query buffer formatted like private messages.
o `erc-show-channel-key-p' - The channel key is now shown with the
other channel modes in the header line. Set this to nil if you
want it hidden.
o `erc-prompt-for-channel-key' - Set this if you want to be prompted
for the channel key (channel's mode is +k) when you call
`erc-join-channel' interactively.
o `erc-kill-server-buffer-on-quit' - If non-nil, kill the server
buffer automatically when you quit.
** New hooks
o `erc-join-hook' - Called when you join a channel.
o `erc-kick-hook' - Called when you are kicked from a channel. The
channel's buffer is sent as an argument to functions called from
this hook.
o `erc-nick-changed-functions' - Whenever your nickname changes
successfully, the functions in this hook are run with the
arguments NEW-NICK and OLD-NICK.
** New command /WHOAMI - Do a /WHOIS on your current nickname.
** The key binding for changing channel modes is now C-c C-o.
** Removed variables
o `erc-echo-notices-in-minibuffer-flag' and
`erc-echo-notices-in-current-buffer' - You should use
`erc-echo-notice-hook' and `erc-echo-notice-always-hook' instead.
o `erc-prompt-interactive-input' has been removed (commented out)
because nickname completion does not work with it.
o All INFO buffer-related variables and functions have been removed.
** You can now disable modules by setting `erc-modules' with the
customization interface.
** Changes and additions to modules
*** Autoaway (erc-autoaway.el)
**** New variable `erc-autoaway-no-auto-back-regexp' - Add text which,
when you type anything matching it, will not automatically discard
your away status when `erc-auto-discard-away' is non-nil.
*** Filling (erc-fill.el)
**** New variable `erc-fill-variable-maximum-indentation' - Don't
indent more than this many characters when indenting a message from a
user with a long nickname.
*** Goodies (erc-goodies.el)
**** Miscellaneous small modules have been moved from erc.el.
The functions erc-add-scroll-to-bottom, erc-make-read-only,
erc-send-distinguish-noncommands, erc-interpret-controls, erc-unmorse,
erc-smiley, and erc-occur, which were defined in the main erc.el file
have been moved to erc-goodies.el and have mostly been translated to
the modules scrolltobottom, readonly, noncommands, irccontrols, smiley
and unmorse.
**** New variables
o `erc-input-line-position' - The line number to use with
`erc-scroll-to-bottom'.
o `erc-beep-p' - Beep if there is a \C-g control character in a
message.
*** Channel lists (erc-list.el)
**** New variable `erc-chanlist-highlight-face' - A face used for
highlighting the current line.
*** Highlighting (erc-match.el)
**** `erc-current-nick-highlight-type' has new options: 'keyword and
'nick-or-keyword.
*** Menu (erc-menu.el)
**** The `IRC' menu is now automatically added to `erc-mode' buffers.
*** Networks (erc-nets.el)
**** The functions for determining current network are in this file.
There were a couple of functions spread about in different files which
each had a different way of determining the current network. The
methods have been combined, and the big list of known networks
(`erc-networks-alist') is being put to use. You can access the
network's name by calling the new function `erc-network'. This
returns the name of the current network as a symbol or 'Unknown if it
could not determine which network it is.
*** Nicklist (erc-nicklist.el)
**** ERC has a new way of displaying nicknames in a channel.
The new file erc-nicklist.el defines a new command `erc-nicklist'
which pops up a small Emacs window showing the nicknames of all
members of the current channel. The implementation is not complete
and is rather proof-of-concept for now. The result is something a bit
like erc-speedbar, but not quite as invasive, and doesn't require use
of a new frame.
*** Internet services / Nickserv (erc-nickserv.el)
**** Network detection is now taken care of by erc-nets.el.
The function `erc-current-network' is deprecated, use `erc-network'
instead. The variable `erc-networks' has been removed, use
`erc-networks-alist'. The network symbols used in
`erc-nickserv-alist' now match those in `erc-networks-alist'.
**** New variable `erc-nickserv-identify-mode' - Choose which method
to use for automatic identification: you can wait for Nickserv to ask
you to identify (the default), or send an identify message
automatically after you change your nickname.
*** Speedbar (erc-speedbar.el)
**** New variable `erc-speedbar-sort-users-type' - Sort users in a
channel by activity, alphabetically, or not at all.
*** Timestamps (erc-stamp.el)
**** `erc-timestamp-only-if-changed-flag' now works when
`erc-insert-timestamp-function' is set to 'erc-insert-timestamp-left.
**** New variable `erc-timestamp-intangible' - Set this to nil if
timestamps should not have the 'intangible property.
*** Channel tracking (erc-track.el)
**** Using faces to indicate channel activity in the modeline now works
in XEmacs.
**** New variables
o `erc-track-priority-faces-only' - Ignore changes in a channel
unless there is a face from the `erc-track-faces-priority-list' in
the message.
o `erc-track-exclude-server-buffer' - Ignore changes in the server
buffer.
o `erc-track-position-in-mode-line' - Set the position in the
mode-line where modified channels are shown (only works in GNU
Emacs versions above 21.3).
* Changes in ERC 4.0
** The module system has again changed a lot. You can now customize
the variable `erc-modules' and define once and for all which
extension modules you want to use. This unfortunately may require
2011-11-20 02:29:42 +00:00
you to change your current erc initialization code a bit, if you
2011-11-15 07:55:13 +00:00
have some existing customizations. On the other hand, this change
makes the configuration of extension modules a lot easier for new
users. In theory, you should be able to configure all aspects of
ERC by using the customize interface, you should no longer really
need to write Lisp code for trivial customizations.
By default, the following modules are now loaded: (pcomplete
netsplit fill track ring button autojoin)
Please use M-x customize-variable RET erc-modules RET to change the
default if it does not suite your needs.
** THe symbol used in `erc-nickserv-passwords' for debian.org IRC servers
(formerly called OpenProjects, now FreeNode) has changed from
openprojects to freenode. You may need to update your configuration
for a successful automatic nickserv identification.
* Changes in ERC 3.0.cvs.20030119
** New module erc-dcc:
This finally implements DCC. It requires server sockets to fully work
in both directions. This feature is currently only available in Emacs
21.3.50 (CVS). Here is a short list of what should work though.
** Compatibility:
* Emacs 21.2, DCC get, and accepting DCC chat offers.
* XEmacs 21, Only accepting DCC chat offers.
** erc is switching to global-minor-modes for activation of submodules.
This allows you to customize such a mode and get automatic loading of
the module. No longer putting a lot of require statements in .emacs.
At least this is the long-term plan, not all modules are converted yet.
** The most important user visible change is that you now need to activate
erc-completion-mode, to get TAB completion. The new completion code
is based on pcomplete. To get the old code, manually load
erc-complete and bind TAB to erc-complete in erc-mode-map.
To activate completion on startup, put (erc-completion-mode 1) in your
.emacs file.
Same applies to timestamps. You no longer need to (require
'erc-stamp), you can customize the variable `erc-timestamp-mode', and
the rest should be automatic.
