Subject: bug#65620: void function edebug-after
Date: Wed, 30 Aug 2023 12:57:29 +0000 [thread overview]
Message-ID: <ZO88uT-KzimjHKaC@ACM> (raw)
Hello, Emacs.
On a recent master branch Emacs:
(i) emacs -Q
(ii) Insert the following into *scratch*:
(defmacro hash-if (condition then-form &rest else-forms)
"A conditional compilation macro analogous to C's #if.
Evaluate CONDITION at macro-expansion time. If it is non-nil,
expand the macro to THEN-FORM. Otherwise expand it to ELSE-FORMS
enclosed in a `progn' form. ELSE-FORMS may be empty."
(declare (indent 2)
(debug (form sexp &rest sexp)))
(if (eval condition lexical-binding)
then-form
(cons 'progn else-forms)))
(defun foo (bar)
(hash-if (< emacs-major-version 19)
(car bar)
(cons bar bar)))
(iii) Evaluate hash-if by putting point after it and doing C-x C-e.
(iv) Attempt to instrument foo for edebug by putting point inside foo and
doing C-u C-M-x. This throws the error: "Ignoring macroexpansion
error: (void-function edebug-after)". This attempt to evaluate
edebug-after is a bug.
