Hello,
When doing C-h v magit*section-map TAB, the corresponding completion
list is shown. Is there an equivalent function which would accept
such a wild card and return the same list? E.g.
(var-symbols "magit*section-map")
Regards,
Alexander

(defun get-regexp-vars (regexp)
(let ((vars '()))
(mapatoms (lambda (a) (when (and (boundp a)
(string-match regexp (symbol-name a)) )
(push a vars) )))
vars))
;; some testing
(length (get-regexp-vars "gnus-.*")) ; 1109
(length (get-regexp-vars "w3m-.*")) ; 445

The function used internally by the completion engine is
completion-all-completions.
