I'd like to make changes to ~/.emacs.d/init.el that change my key bindings for clojure/cider mode and re-evaluate these changes without having to quit/restart emacs. This would make it easy to iteratively test new keybindings.
I mention clojure/cider specifically, but I haven't gotten this to work with modes other than emacs-lisp mode (i.e. org mode).
To reevaluate the entire init file type M-x eval-buffer in a buffer visiting it, or M-: (load-file user-init-file) to reload without visiting it.
However, if your intention is to iteratively add new keybindings or code to your running Emacs session I recommend not to evaluate the entire buffer but instead use C-M-x (aka eval-defun) to evaluate only the current function or top-level definition or M-x eval-region to evaluate selected code.
