`string-words'

[Emanuel Berg]

I've been writing some Elisp, some of it turned up all-Emacs.

Maybe it already exists in Emacs or ELPA, if so I'd be happy
to use that instead. Are there any options?

If not, this is a candidate for a string library.

;;; -*- lexical-binding: t -*-

(defun string-words (str &optional no-sort keep-case)
  (or keep-case (setq str (downcase str)))
  (let ((words (split-string str "[[:space:]()]+" t "[[:punct:]]+")))
    (if no-sort
        words
      (sort words) )))
