From: Gemini Lasswell <gazally <at> runbox.com> To: bug-gnu-emacs <at> gnu.org Subject: 26.0.50; Error when using Edebug on a function that uses :documentation Date: Sun, 23 Oct 2016 08:28:22 -0700
Edebug gives an error when you try to debug any function which uses :documentation to create its docstring. To reproduce: 1. Start Emacs (with -Q if you like) and enter the following code into *scratch*: ;;; -*- lexical-binding: t -*- (defun make-animal (species noise) (lambda () (:documentation (format "I'm a %s." species)) (message "%s" noise))) (defalias 'kermit (make-animal "frog" "ribbit")) (message "Kermit says %s" (documentation 'kermit t)) (kermit) 2. M-x edebug-all-defs RET 3. M-x eval-buffer RET 4. g Result: "Kermit says nil" is written to Messages, and execution stops with the error "Symbol’s function definition is void: :documentation". This bug happens not only with lambda but also defun, defmacro, defmethod, pcase-lambda, cl-defun, etc. In GNU Emacs 26.0.50.10 (x86_64-apple-darwin15.6.0, NS appkit-1404.47 Version 10.11.6 (Build 15G1004)) of 2016-10-22 built on rainbow.local Repository revision: f577b8efec324afc80aa4308efbfa40dcce30bbf Windowing system distributor 'Apple', version 10.3.1404 Recent messages: Edebugging all definitions is on.
