How can I reload .emacs after changing it?

Question

How can I get Emacs to reload all my definitions that I have updated in .emacs without restarting Emacs?

Answer 1

You can set key-binding for emacs like this

;; reload emacs configuration
(defun reload-init-file ()
  (interactive)
  (load-file "~/.emacs"))

(global-set-key (kbd "C-c r") 'reload-init-file) 

Hope this will help!
