Thanks, pushed to `emacs-29`.

Thanks, pushed to `master`.

Indeed, hereby closing it as well.

Yes (it's easy to undo, in any case if it proves to be a mistake).

Subject: 29.0.50; elisp-completion-at-point don't complete local variables
 when using setq
Date: Sun, 16 Oct 2022 01:25:28 +0800

elisp-completion-at-point will not complete local variables when using setq.

Tested with emacs -Q, latest Emacs master

Steps to Reproduce:

Snippet a:
(let (foo foo-foo bar bar-bar)
  (setq foo))
               ^

^ marked cursor position.

When pressing C-M-i (completion-at-point), no local variable completion will be provided.

And I found out it was related with elisp--local-variables and macroexpand-all:


Debug snippet:

Snippet b:

(let ((macroexpand-advice (lambda (expander form &rest args)
                            (condition-case nil
                                (apply expander form args)
                              (error form)
                              ))))
  (unwind-protect
      (progn
        (advice-add 'macroexpand :around macroexpand-advice)
        (macroexpand-all
         '(setq elisp--witness--lisp)))
    (advice-remove 'macroexpand macroexpand-advice)))

Return value in Emacs 29.0.50: 

(signal 'wrong-number-of-arguments
        '(setq 1))


I also tested those two steps on Emacs 28.2, released version 
with emacs -Q,

and with following system-configuration-features:
"ACL GMP GNUTLS JSON LIBXML2 MODULES NOTIFY 
KQUEUE NS PDUMPER THREADS TOOLKIT_SCROLL_BARS ZLIB”

completion-at-point worked normally in Snippet a.

Return value of Snippet b is:

(setq elisp--witness--lisp)
