It is closer in style to this shell script and Unix tool parsing which does the same thing: $ str=$(printf '616e6f6e796d6f75732d6c616d626461' | sed 's,..,\\x&,g') $ printf '%b\n' "$str" anonymous-lambda Anyway I added it to my hex.el file with a reference to your post on the gnu.emacs.devel archives, see URL below. ;;; -*- lexical-binding: t -*- ;; ;; this file: ;; https://dataswamp.org/~incal/emacs-init/hex.el ;; ;; original code: ;; https://stackoverflow.com/a/12007656 ;; https://lists.gnu.org/archive/html/emacs-devel/2023-12/msg00947.html (require 'cl-lib) (defun decode-hex-2 (str) (replace-regexp-in-string ".."
