Subject: bug#36066: 27.0.50; Error for C-h f in help-fns--first-release
Date: Mon, 03 Jun 2019 04:09:40 +0200 [thread overview]
Message-ID: <87tvd7to63.fsf@web.de> (raw)
Hello,
for some functions I can't show *Help* with C-h f because I get an error
like this:
Debugger entered--Lisp error: (wrong-type-argument integer-or-marker-p nil)
add-text-properties(nil nil (button (t) category #:help-news-button help-args nil) nil)
make-text-button(nil nil type help-news help-args nil)
help-fns--first-release(my-edebug-setup-hook-fun)
help-fns--mention-first-release(my-edebug-setup-hook-fun)
run-hook-with-args(help-fns--mention-first-release my-edebug-setup-hook-fun)
describe-function-1(my-edebug-setup-hook-fun)
describe-function(my-edebug-setup-hook-fun)
Seems the variable "first" is never set and ends up nil, thus the error.
It often happens to functions in my init file FWIW.
BTW, the calculation/heuristic also seems not very clever in some cases.
E.g. in emacs -Q I define
(defun f () nil)
C-h f f
f is a Lisp closure.
(f)
Probably introduced at or before Emacs version 1.6.
(defun test () nil)
C-h f test
test is a Lisp closure.
(test)
Probably introduced at or before Emacs version 15.
Etc. Shouldn't it be obvious to Emacs that I defined the functions?
TIA,
Michael
