Is "logger" some function that exists in Emacs, or should I simply make it? (defun rcd/emacs-lisp-log (log) "Allows functions to log their usage" (let* ((function (second (backtrace-frame 5 nil))) (timestamp (format-time-string "%Y-%m-%d-%H:%M:%S")) (log (format "%s %s %s\n" timestamp function log)) (save-silently t)) (with-temp-buffer (insert log) (append-to-file (point-min) (point-max) *emacs-lisp-log*)))) (defun rcd-space () (interactive) (rcd/emacs-lisp-log "SPACE") (self-insert-command 1 32)) Then I made global-set-key SPC to rcd-space and now I log each SPACE as *emacs-lisp-log* is like ~/tmp/lisp.log. Typing is not obstracted. It is useful for self supervision.
