* doc/misc/erc.texi: Replace option `erc-format-nick-function' with `erc-show-speaker-membership-status'. * etc/ERC-NEWS: Mention shift to template-based speaker formatting. Also mention in-buffer STATUSMSG support and various name changes and new formatting-related options. * lisp/erc/erc-backend.el (erc-format-privmessage): Remove forward declaration. (erc--determine-speaker-message-format-args): Add forward declaration. (erc--statusmsg-target): New utility function for detecting whether the current target is status-prefixed. (erc-current-message-catalog): Move here from lisp/erc/erc.el. (erc--message-speaker-catalog): New variable. (erc--speaker-status-prefix-wanted-p): New variable specifically for the function `erc-format-@nick' to signal it wants status-prefixes prepended to the displayed nick. (erc-server-PRIVMSG): Initialize `let'-bound value of `erc--msg-prop-overrides' to a dummy `erc--tmp' property with a null value that `erc-display-message' will "strip" before calling its hooks. Move away from the rather blunt symbol `msg' as a useful value for `erc--msg'. Instead, allow `erc-display-message' to assign the most appropriate value based on context. Also, bind the variable `erc-current-message-catalog' to whatever the buffer's `erc--message-speaker-catalog' happens to be. Future internal modules can set this to alternative catalogs as needed. Additionally, detect STATUSMSG prefixes on targets and inform the formatting logic of the verdict. Lastly, and most importantly, use the function `erc--determine-speaker-message-format-args' instead of `erc-format-privmessage' for message formatting. Pass along the returned "catalog key" and spec parameters to `erc-display-message'. However, for NOTICEs, continue to render the string, as before, for the two "echo notice" hooks. * lisp/erc/erc-common.el (erc--ctcp-response): New "subsclass" of `erc-response' for smuggling extra information to CTCP query handlers in a mostly backwards-compatible way. The same approach could be taken with the "echo notice" hooks mentioned above. * lisp/erc/erc-dcc.el (erc-dcc-chat-filter): Add `erc--spkr' and `erc--speaker' properties even though these chat buffers are not `erc-mode' buffers. * lisp/erc/erc-fill.el (erc-fill--wrap-last-msg, erc-fill--wrap-max-lull): Add doc strings. (erc-fill--wrap-continued-message-p): Rework to look for `erc--spkr'- `erc--msg' combinations as indicators of speaker continuity. (erc-fill--wrap-rejigger-region): Remove reference to the no longer relevant `erc-stamp-type'. Instead, use the `erc--msg' property combined with the `erc-timestamp' field to detect date stamps because all are currently left-sided. * lisp/erc/erc-stamp.el (erc-stamp--propertize-left-date-stamp): Don't add superfluous `erc-stamp-type' property. * lisp/erc/erc.el (erc--msg-props): Revise purpose and meaning of `erc--msg' by removing possible value `msg', which was previously meant to indicate that a message had a "speaker". Instead, rely on the separate `erc--spkr' property to convey this information, with `erc--msg' now expressing a "type" or "role". (erc--use-language-catalog-for-ctcp-action-p): New variable, a compatibility switch to help transition from the `ACTION' entry of the language catalog to the `ctcp-action' family of entries in the new `-speaker' catalog. (erc--ensure-spkr-prop): Update to include any passed-in environmental overrides. (erc--send-action-display): Restore pre-5.6 behavior when compatibility flag enabled. Otherwise, use new `-speaker' catalog for formatting inserted message. (erc--send-message-external): Overhaul to behave more faithfully in mimicking a line submitted at the prompt of the current target buffer. (erc--own-property-names): Remove `erc-stamp-type'. (erc-ensure-target-buffer-on-privmsg): Add new choice variant for old default behavior and change meaning of default to mean "except for STATUSMSGs". This option is newly revived for ERC 5.6. (erc--message-speaker-statusmsg, erc--message-speaker-statusmsg-input, erc--message-speaker-input, erc--message-speaker-input-chan-privmsg, erc--message-speaker-input-chan-notice, erc--message-speaker-input-query-privmsg, erc--message-speaker-input-query-notice, erc--message-speaker-chan-privmsg, erc--message-speaker-query-privmsg, erc--message-speaker-chan-notice, erc--message-speaker-query-notice, erc--message-speaker-ctcp-action, erc--message-speaker-ctcp-action-input, erc--message-speaker-ctcp-action-statusmsg, erc--message-speaker-ctcp-action-statusmsg-input): New variables for new `speaker' format-template catalog. (erc--speakerize-nick): New helper function. (erc--determine-speaker-message-format-args): New function to find the appropriate format key from various contextual parameters. Could become the default of a function-valued variable for internal use. (erc-show-speaker-membership-status): New option. (erc-format-nick-function, erc-speaker-from-channel-member-function): Declare former as an obsolete alias for the latter, and redefine purpose slightly. (erc-format-nick-function, erc-determine-speaker-from-user): Rename former to latter and obsolete the old name. (erc-format-nick, erc-determine-speaker-from-user): Rename former to latter and obsolete old name. (erc-format-@nick): Deprecate and adapt for use with new template-based formatting paradigm. (erc-format-my-nick): Move `erc-speaker' text prop toward head of list, meaning it will end up beneath `font-lock-face' in the final output. (erc--format-speaker-input-message): New function to replace `erc-format-my-nick' in-tree. (erc-process-ctcp-query): Don't bind `erc--msg' to `msg'. Instead, rely on `erc-display-message' to set it to the current template key. (erc-ctcp-query-ACTION): Prefer using formatting template, but attempt to simulate pre-5.6 behavior when compatibility flag enabled. (erc-display-msg): Use `erc--format-speaker-input-message' instead of `erc-format-my-nick'. Ignore `erc--msg-prop-overrides' with null values. (erc-current-message-catalog): Move to erc-backend.el. * test/lisp/erc/erc-scenarios-base-statusmsg.el: New file. * test/lisp/erc/erc-scenarios-stamp.el (erc-scenarios-stamp--left/display-margin-mode): Expect format catalog key instead of unhelpful `msg' as value of `erc--msg' prop. * test/lisp/erc/erc-tests.el (erc-message): Render format template in mock function and expect string in assertions. (erc-tests--format-privmessage): New function, a helper for the following test. (erc-format-privmessage, erc--determine-speaker-message-format-args): Rename former to latter and suppress deprecation warning. (erc--determine-speaker-message-format-args/queries, erc--determine-speaker-message-format-args/queries-as-channel): New tests. (erc-tests--format-my-nick): New helper function for the following test. (erc--format-speaker-input-message): New test. * test/lisp/erc/resources/base/display-message/statusmsg.eld: New file. (Bug#67677) ; * test/lisp/erc/resources/fill/snapshots/merge-wrap-01.eld: Update. ; * test/lisp/erc/resources/fill/snapshots/merge-wrap-indicator-post-01.eld: ; Update. ; * test/lisp/erc/resources/fill/snapshots/merge-wrap-indicator-pre-01.eld: ; Update. |
