bug#66410: 28.2; Symbol’s function definition is void: command-query

[Paul Stansell]

[-- Attachment #1: Type: text/plain, Size: 15877 bytes --]

Hello,

The following command is given as an example on
https://www.gnu.org/software/emacs/manual/html_node/emacs/Disabling.html

  (command-query
   'end-of-buffer
   "Do you really want to go to the end of the buffer?")

However, when I try it in my emacs init.el get this error

  load-with-code-conversion: Symbol's function definition is void:
command-query

Thanks,

Paul

This online manual is for Emacs version 29.1 (as you can see if you
click the "Contents" link at the top of that page),

and `command-query' was first added to Emacs in version 29.1,

but you are evidently using Emacs 28.2, that's why it doesn't know
`command-query'.  But the definition is short:

(defun command-query (command query &optional verbose)
  "Make executing COMMAND issue QUERY to the user.
This will, by default, use `y-or-n-p', but if VERBOSE,
`yes-or-no-p' is used instead."
  (put command 'disabled
       (list 'query (not (not verbose)) query)))

so you could add it to your init file before the above use of it.  (But
if you later update to Emacs 29.1 or later, you should then remove the
definition from your init file.)

I'd use this:

(when (< emacs-major-version 29)
  (defun command-query (command query &optional verbose)
    "Make executing COMMAND issue QUERY to the user.
This will, by default, use `y-or-n-p', but if VERBOSE,
`yes-or-no-p' is used instead."
    (put command 'disabled
         (list 'query (not (not verbose)) query))))

I don't see a bug here, so I'm closing this now.  Thanks.

Hello Stefan and Stephen,

I'm very sorry that I didn't notice the version differences.  Thanks very
much for your advice on how I can get the functionality.
