Alert info is missing :data, preventing links to messages working about ol-emacs-slack

[ag91]

right, sorry! I forgot to mention that emacs-slack needed an edit: ag91/emacs-slack@1f2ae6c

Could you try to define the following function and try again?

(defun slack-message-notify-alert (message room team)
  (if (slack-message-notify-p message room team)
      (let ((team-name (oref team name))
            (room-name (slack-room-name room team))
            (text (with-temp-buffer
                    (goto-char (point-min))
                    (insert (slack-message-to-alert message team))
                    (slack-buffer-buttonize-link)
                    (buffer-substring-no-properties (point-min)
                                                    (point-max))))
            (user-name (slack-message-sender-name message team)))
        (if (and (eq alert-default-style 'notifier)
                 (slack-im-p room)
                 (or (eq (aref text 0) ?\[)
                     (eq (aref text 0) ?\{)
                     (eq (aref text 0) ?\<)
                     (eq (aref text 0) ?\()))
            (setq text (concat "\\" text)))
        (alert (if (slack-im-p room) text (format "%s: %s" user-name text))
               :icon slack-alert-icon
               :title (if (slack-im-p room)
                          (funcall slack-message-im-notification-title-format-function
                                   team-name room-name (slack-thread-message-p message))
                        (funcall slack-message-notification-title-format-function
                                 team-name room-name (slack-thread-message-p message)))
               :category 'slack))))
               :category 'slack
               :data (list
                      :team-id (slack-team-id team)
                      :room-id (oref room id)
                      :room-name (slack-room-name room team)
                      :team-name (oref team name)
                      :ts (slack-ts message)
                      :formatted-ts (ts-format "[%H:%m]" (ts-now)))))))
