reloading emacs

reloading emacs

[Jim Hurley]

Hello,

Was just wondering how I could tie the reloading of 
.emacs to a function key. This seems desirable to
quickly check changes I make to the file.

Thanks.

For this purpose, I have this on my .emacs:

(global-set-key [f2] 'eval-buffer)

(defun reload-dot-emacs ()
  "Reload the .emacs file."
  (interactive)
  (load "~/.emacs"))

(global-set-key ... 'reload-dot-emacs)

There are possible improvements that could be made; for instance, if the
.emacs file is currently in a buffer, and it's not saved out, the command
could ask whether to save it first.

If you do this, be aware that loading .emacs again is not the
equivalent of starting a fresh emacs, especially if you add things to
load-path, or simply remove a setq of a defvar-ed variable.  Also,
existing buffers and variables not mentioned by .emacs will survive,
etc.  

For your question, look into load-file or eval-buffer or (perhaps most
relevant) eval-current-buffer.

Use add-to-list to prevent adding elements more than once.

(global-set-key [f9] (lambda (&rest args) (interactive) (load "~/.emacs")))

Do not adjust your mind, there is a fault in reality.

Even that will not remove whatever was "add-to-list"ed in the previous
incarnation of .emacs, though.

Not a big deal, but I think my basic point stands.

True.

Agreed, my followup was just minor comment.
