dougm / json-snatcher

Get the path to a JSON element in Emacs.

#json-snatcher.el

Say you're looking through a large JSON file, and see a value that you want to extract programmatically. This Emacs extension will allow you to snatch the path to this value.

Available on MELPA at http://melpa.milkbox.net/#/json-snatcher .

Installation

First include the package

(require 'json-snatcher)

Then add the following lines to your .emacs file, which sets a hotkey when editing JSON files in either js or js2 mode

(defun js-mode-bindings ()
"Sets a hotkey for using the json-snatcher plugin"
	 (when (string-match  "\\.json$" (buffer-name))
        (local-set-key (kbd "C-c C-g") 'jsons-print-path)))
(add-hook 'js-mode-hook 'js-mode-bindings)
(add-hook 'js2-mode-hook 'js-mode-bindings)
