-;; Pretty-print tries during edebug
+;; Pretty-print tries during edebug
-;; Note:
-;; -----
-
-;; We advise the `edebug-prin1' and `edebug-prin1-to-string' functions
-;; (actually, aliases) so that they pring "#<trie>" instead of the full
-;; print form for tries.
+;; We use `cedet-edebug-add-print-override' from cedet-edebug.el to make
+;; edebug print "#<trie>" instead of the full print form for
+;; tries. (This is cleaner than using aliases or advice.)
;;
;; This is because, if left to its own devices, edebug hangs for ages
;; whilst printing large tries, and you either have to wait for a *very*
;; long time for it to finish, or kill Emacs entirely. (Even C-g C-g
-;; fails!)
-;;
-;; Since the print form of a trie is practically incomprehensible
-;; anyway, we don't lose much by doing this. If you *really* want to
-;; print tries in full whilst edebugging, despite this warning, disable
-;; the advice.
-;;
-;; FIXME: Should use `cedet-edebug-prin1-extensions' instead of advice
-;; when `cedet-edebug' is loaded, though I believe this still
-;; works in that case.
