Reload .emacs

Reload .emacs

[Henrik Austad]

Hi all!

I'm configuring my emacs22.1, and I catch myself restarting emacs (quit and start) for every change. 
Are there any ways of just reloading the .emacs-file without restarting emacs? 

I've googled for 'emacs reload config' and variants thereof, but I'm not finding a useful guide. 

If there are places I *should* have read before bugging you with these kind of questions, please let me 
know - I don't mean to annoy you! :-)

thanks

Not really. An init file can do other things than some other Elisp  
file. Elisp libraries or files can get loaded/reloaded depending on  
variables set/reset/unset ...

BTW, what do you mean with "I'm configuring my emacs22.1?"

How about eval-buffer?

,----[ C-h f eval-buffer RET ]
| eval-buffer is an interactive built-in function in `C source code'.
| (eval-buffer &optional BUFFER PRINTFLAG FILENAME UNIBYTE DO-ALLOW-PRINT)
| 
| Execute the current buffer as Lisp code.
| Programs can pass two arguments, BUFFER and PRINTFLAG.
| BUFFER is the buffer to evaluate (nil means use current buffer).
| PRINTFLAG controls printing of output:
| A value of nil means discard it; anything else is stream for print.
| 
| If the optional third argument FILENAME is non-nil,
| it specifies the file name to use for `load-history'.
| The optional fourth argument UNIBYTE specifies `load-convert-to-unibyte'
| for this invocation.
| 
| The optional fifth argument DO-ALLOW-PRINT, if non-nil, specifies that
| `print' and related functions should work normally even if PRINTFLAG is nil.
| 
| This function preserves the position of point.

Or even eval-last-sexp.  That's what I use all the time, if I have
made one change in .emacs, I place the cursor after the changed
definition or whatever and hit C-x C-e.

You can manually evaluate the additions you make.  Go to the closing
parenthesis of each expression and type "C-x C-e".

Alternately, if you've done a lot of work, you can highlight the
region and do "M-x eval-region RET" to evaluate it, or if you've
changed the whole buffer you can do "M-x eval-buffer RET", but I
wouldn't generally advise that for reloading the init file because
there might be things in there that'll toggle, which could mess
things up for you.

Then you should probably fix your setup.  Some examples:

Instead of...
  (foo-bar-mode);; toggle foo-bar mode
use...
  (foo-bar-mode 1);; enable foo-bar mode

Use `add-to-list' instead of `push'.  Etc.

Is there a specific reason why you need to reload the whole file? 

I usually just make changes in the file and put cursor at the end of the sexp
and hit C-x C-e to eval it.

I'm writing a more general reply since I've gotten a lot of answers and 
input, thank you all!

I'm now using C-x C-e to eval the expression, and that was (even though 
I didn'n know it) exactly what I needed.

Again, thank you for all you help!
