Title: Unable to create key binding.

Title: Unable to create key binding.

*Title: Unable to create key binding.*

Hello All:

Below is the code for node.js REPL ( see below ).

I was not able to use the key bindings.

I got “Undefined … “ response from emacs.


 However, I was able to run commands like this:

M-x run-js and M-x js-send-last-sexp


 When I ran command, C-h b, I see these key bindings:

C-c & C-s yas-insert-snippet


 C-c C-r comint-show-output

C-c C-s comint-write-output


 Questions:

Q1: from command, C-h b, kkey bindings list as shown above, what is the
difference between

C-c & C-s and C-c C-s ?


 Q2: Are the existing key bindings conflict with the key bindings show in
code below?


 Q3: What to do now?


 ;;================= Node.js REPL ==============

; Lifted from
http://howardabrams.com/projects/dot-files/emacs-javascript.html

;Server JS with Node.js

;Use js-comint, but hook it up with node.js:


 ; Use require instead of autoload

(require 'js-comint)

;(autoload 'js-comint "js-comint"

; "Hooking JavaScript interpreter up to the JS Files." t nil)


 (setenv "NODE_NO_READLINE" "1") ;; Turn off fancy node prompt

;; Use node as our repl

(setq inferior-js-program-command "node")


 ;According to these instructions ( iink to nodejs.org ), we set the
NODE_NO_READLINE variable.

;Need some prompt configuration for the REPL:


 (setq inferior-js-mode-hook

(lambda ()

;; We like nice colors

(ansi-color-for-comint-mode-on)

;; Deal with some prompt nonsense

(add-to-list

'comint-preoutput-filter-functions

(lambda (output)

(replace-regexp-in-string "\033\\[[0-9]+[GK]" "" output)

(replace-regexp-in-string ".*1G.*3G" ">" output)

(replace-regexp-in-string ">" "> " output)))))


 ;Start the JavaScript node REPL with: run-js Set up some helpful keyboard
instructions:

;; Unable to make key binding work

(add-hook 'js2-mode-hook

(lambda ()

(local-set-key (kbd "\C-c\C-c") 'js-send-buffer)

(local-set-key (kbd "\C-c\C-r") 'js-send-region)

(local-set-key (kbd "\C-c\C-s") 'js-send-last-sexp)

(local-set-key (kbd "\C-c\C-z") 'run-js)))

;================ end of Node.js REPL setup =============


Thank you & Cheers,

For the former, you must press Control and type c, type &, press Control
and type s, while for the later, you just press Control and type c, and
press Control and type s.

You should better ask this question to emacs itself!
For example, in this buffer:

    (some (lambda (key) (key-binding key))
          (list (kbd "\C-c\C-c") (kbd "\C-c\C-r")
                (kbd "\C-c\C-s") (kbd "\C-c\C-z")))
    --> message-send-and-exit

Whatever you want.  Key binding are up to the user to customize just
like she wants!
