Re: Tracing what is loading

[Michael Heerdegen]

Please note that there already _is_ a message for every file loaded. But
because the *Messages* buffer only shows the last 50 (or so) messages,
you can't see them because starting up causes quite more messages.

Indeed all you need is `load-history'. Due to the internal structure of
lists, the last item belongs to the first load file and vice versa, so you
must read it bottom up.

I have written a command which only shows the files, in the right order:

(defun list-load-files () (interactive)
  (with-current-buffer
      (get-buffer-create "*Load History*")
    (erase-buffer)
    (insert (format "%s" "Load History\n============\n\n"))
    (mapc
     (lambda (x) (insert (format "%s\n" (car x))))
     (reverse load-history))
    (pop-to-buffer (current-buffer))))

You can eval it with M-:. Call it with M-x list-load-files.

The listing should cover all lisp files ever loaded after startup.
