From: F. Jason Park Date: Sat, 2 Sep 2023 20:43:22 +0000 (-0700) Subject: Tidy up ERC's internal text-property API X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=9acd8c8e530dda326ae5bf852c2437fdcde4e8cc;p=emacs.git Tidy up ERC's internal text-property API * lisp/erc/erc-fill.el (erc-fill--spaced-commands): Remove unused internal variable originally intended for ERC 5.6. (erc-fill): Check for `erc-msg' being `msg', which carries the same meaning as `erc-cmd' being `PRIVMSG' or `NOTICE', except that inserted outgoing messages now no longer normally have an `erc-cmd' property. (erc-fill-wrap-mode, erc-fill-wrap-disable): Kill `erc-fill--wrap-last-msg'. (erc-fill--wrap-max-lull): Convert from buffer-local to normal variable. (erc-fill--wrap-continued-message-p): Rework slightly to guard against resetting the "last speaker" marker when the `erc-ephemeral' text property is present. This tells insert- and send-related hook members to pretend the current message doesn't exist when performing stateful operations. That is, modules should expect the message being inserted to possibly disappear or be replaced. Also, look for `erc-msg' being `msg' instead of `erc-cmd' being `PRIVMSG', and fix bug involving only checking `erc-ctcp' in the current message. * lisp/erc/erc-stamp.el (erc-add-timestamp): Don't insert timestamps when the `erc-ephemeral' text property is present. * lisp/erc/erc.el (erc--msg-props): Add doc string explaining the purpose of this variable and the various text properties most commonly present in its value. (erc--msg-prop-overrides): Add doc string. (erc-send-action): Don't set `erc-cmd' prop on outgoing CTCP ACTIONs. (erc-display-message): Reverse overrides to prefer items toward the front of the alist. (erc-process-ctcp-query): Include existing overrides from environs. (erc-send-current-line): Include existing overrides from environs. (erc-display-msg): Fix doc string and reverse overrides. * test/lisp/erc/erc-fill-tests.el (erc-fill-tests--insert-privmsg): Remove stray comment. (erc-fill-tests--save-p): Set value from environment variable. (erc-fill-tests--compare): Limit writing snapshots to one test at a time. (erc-fill-wrap--merge-action): Fix expected output for non-action messages that follow action messages. These were previously merged but escaped detection. * test/lisp/erc/resources/fill/snapshots/merge-wrap-01.eld: Update.
