This is a real newby question. I have a load of buffers in emacs and I
edit .emacs with some new cool macro or what ever. To get the new code
working I could close and restart emacs, but I will have to re-load
every buffer. Is there an easy way to either 1) get the new lisp code
working without closing and reopening, or 2) close and reopen and
still have all the same buffers available so I don't have to open
easch manually.

peace
Dave

my bad, forgot to hit 'g' (group reply)

C-x C-e right after the code.

Evaluate it in the *scratch* buffer.

Use desktop.el and/or session.el.

The load-file function evaluates all the elisp functions in a given
file.  To apply this to your cool macros, do

M-x load-file RET ~/.emacs

Whilst you work on your .emacs, it may be an idea to bind this to some
key

(global-set-key '[f2] (lambda () (load-file "~/.emacs")))

Another yet simpler solution would be only to evaluate the new cool
funtion or macro, e.g.

(defun my-cool-function ()
   ...)
        \
         \
      Place point behind the last closing paren and press `C-x C-e'.

| It is bound to C-x C-e.
| (eval-last-sexp EVAL-LAST-SEXP-ARG-INTERNAL)

Thanks guys for the pointers. By the way anyone know what Ernst Mach
is referring to at the end of Pete's email? (It clearly wasn't
evaluating LISP code).

Dave

C-x C-e runs the command eval-last-sexp

That's the simplest way: others are

M-x eval-buffer RET
M-x load-file RET ~/.emacs

Rerunning the entire file can cause problems.  Some code may not be 
idempotent - it does different things if you run it more than once.  An 
example would be code that appends.

Good point: I notice that when I run my .emacs after everything has
loaded, my colors change slightly.
