Source Code

;; Defined in /usr/src/emacs/lisp/gnus/gnus-topic.el.gz
(defun gnus-topic-sort-topic (topic func reverse)
  ;; Each topic only lists the name of the group, while
  ;; the sort predicates expect group infos as inputs.
  ;; So we first transform the group names into infos,
  ;; then sort, and then transform back into group names.

          (mapcar #'gnus-info-group
                  (sort (mapcar #'gnus-get-info (cdr topic)) func)))
  ;; Do the reversal, if necessary.
