Subject: Re: removing #'s From: Erik Naggum <email@example.com> Date: 1997/12/02 Newsgroups: comp.lang.lisp Message-ID: <firstname.lastname@example.org> * Kamal Nazar | Can anyone lend a hand ..... | | I have a program that formats its input to produce output lists. | However, the output contains #'s - I will explain ... | REQUIRED OUTPUT ( ((00) (01) (01)) ( (00) (11) (...))) | ACTUAL OUTPUT ( ( #1=(00) (01) (01) ) ( #1# (01) (...)))) | | i.e. Lisp uses these hashes as a shorthand label, | I want the ouput expressed without using this notation - | can anyone tell me what I'm doing wrong, or how to turn off | this behavior ?? your Lisp is trying to produce output that can be read back and produce a result that is as close to the object written out as possible. a number of printer variables control this behavior, but in your case, *print-circle*, if non-nil, causes the Lisp printer to remember which objects it has previously printed and label them. (setq *print-circle* nil) will cause the printer to output the objects without any such attempts. (it's called *print-circle* because the labels are mostly useful when printing circular structures.) #\Erik -- if you think this year is "97", _you_ are not "year 2000 compliant". see http://sourcery.naggum.no/emacs/ for GNU Emacs 20-related material.
