By setting `print-circle' to `t', printing Lisp Object with recursive or repetitive list should be displayed as #N= and #N# syntax. However, it seems this is not true when printing lisp objects within hash tables (which become possible in Emacs 23.1.50.) Following is an example. Is it possible to display the repetitive lisp object within printed hash tables by #N= and #N# syntax, when `print-circle' is set to `t'? I notify this behavior as a bug, but it may not be so. I apologize in that case. (let ((print-circle t) (x (list 10 20)) (y (make-hash-table))) (insert (format "%S\n" (list x x))) (puthash 1 x y) (puthash 2 x y) (insert (format "%S\n" y)) (setcar x 3) (insert (format "%S\n" y))) Result: > (#1=(10 20) #1#) > #s(hash-table size 65 test eql rehash-size 1.5 rehash-threshold 0.8 > data (1 (10 20) 2 (10 20))) > #s(hash-table size 65 test eql rehash-size 1.5 rehash-threshold 0.8 > data (1 (3 20) 2 (3 20))) nil Cordially Yours, -- --------------------------------------------------------------------- 　KAWABATA, Taichi　　　E-mail: kawabata.taichi@gmail.com From monnier@faina.iro.umontreal.ca Mon Nov 30 13:08:41 2009 Received: (at 5082-done) by emacsbugs.donarmstrong.com; 30 Nov 2009 21:08:41 +0000 X-Spam-Checker-Version: SpamAssassin 3.2.5-bugs.debian.org_2005_01_02 (2008-06-10) on rzlab.ucr.edu X-Spam-Level: X-Spam-Bayes: score:0.5 Bayes not run. spammytokens:Tokens not available. hammytokens:Tokens not available.
