Is there any change I can disable the lispy key bindings about lispy HOT 5 CLOSED

Its a void variable probably because you're attempting to set the key before the mode is loaded. You should double check that lispy is loaded before trying to define the key in the map.

from lispy.

OK, eval-after-load solved this Debugger entered--Lisp error: problem.

But the real problem is I cannot disable a key binding defined in lispy.

I have to quote my real problem.

lispy-newline-and-indent-plain basically do nothing but newline-and-indent, the thing is I made a defun in my .emacs to make RET more powerful, so the (define-key map (kbd "RET") 'lispy-newline-and-indent-plain) in lispy.el is in conflict with my RET.

and

And there is another function called lispy-move-end-of-line, but I got a more powerful customized C-e, I really need to disable lispy-move-end-of-line.

I believe there are more examples like these two.

So as I said in #30, since you use a lot of lispy-xx to replace the default bindings, I hope you can give us the abilities to disable them if we want, but I tries many ways, I cannot disable a single key binding defined in lispy.

If there is no way I can disable key binding of lispy without touching lispy.el, you should modify lispy package, check out rebox2

from lispy.

The simplest way to redefine bindings is like this:

(require 'lispy)
(define-key lispy-mode-map (kbd "RET") 'newline-and-indent)

Here's the actual approach that I'm using (requires use-package package):

(use-package lispy
    :load-path "~/git/lispy"
    :init
    (progn
      (define-key lispy-mode-map (kbd "φ") 'lispy-parens)
      (define-key lispy-mode-map (kbd "σ") 'lispy-braces)
      (define-key lispy-mode-map (kbd "ρ") 'lispy-brackets)
      (define-key lispy-mode-map (kbd "θ") 'lispy-quotes)
      (define-key lispy-mode-map (kbd "C-φ") 'lispy-parens-down)
      (define-key lispy-mode-map (kbd "χ") 'lispy-out-forward)
      (define-key lispy-mode-map "π" 'lispy-ace-char)
      (define-key lispy-mode-map "κ" 'lispy-ace-paren)
      (define-key lispy-mode-map (kbd "C-M-a") 'lispy-beginning-of-defun)
      (define-key lispy-mode-map (kbd "C-x C-j") 'lispy-debug-step-in)
      (define-key lispy-mode-map (kbd "C-8") nil)
      (define-key lispy-mode-map (kbd "C-9") nil)))

from lispy.

To disable a binding of lispy-mode and have the global one take over,
do this:

(define-key lispy-mode-map (kbd "RET") nil)

from lispy.

I know why I failed to disable the RET in lispy, because I disable it in

 (add-hook 'emacs-lisp-mode-hook 
      (lambda () 
           '(progn 
                (lispy-mode 1)
                (define-key lispy-mode-map (kbd "RET") nil))))

it will fail, or in

(eval-after-load "lispy-mode"
    '(define-key lispy-mode-map (kbd "RET") nil))

it should be "lispy" not "lispy-mode".
