I guess this is not what you want. It's supposed to be used for reading FILE into VAR. In practice I didn't use them since these were better suited ... (defun file-to-string (file) "A string with the contents of FILE."

Okay, but how do you check if it's an expression? Also take a look at this, one should have a cache function and a function to store arbitrary data and datastructures and the corresponding to load seam-/losslessly into the same Lisp datastructures all tho these are not the same/unaware of the ones that was used (refered to) when saving ... ;;; -*- lexical-binding: t -*- ;; ;; this file: ;; https://dataswamp.org/~incal/emacs-init/cache.el (let ((cache-file (format "%svar/data-cache.el" user-emacs-directory))) (defun save-char-table () (with-temp-buffer (insert "(setq standard-display-table\n\n") (prin1 standard-display-table (current-buffer)) (insert "\n\n)") (write-file cache-file) )) (declare-function save-char-table nil) (defun load-char-table () (when (file-exists-p cache-file) (load-file cache-file) )) (declare-function load-char-table nil) ) (defun set-replacement-char-table () (unless (load-char-table) (let ((tbl standard-display-table)) ;; WARNING, ugly code ahead!
