+;;; json-snatcher.el --- Grabs the path to JSON values in a JSON file -*- lexical-binding: t -*-
+
+;; Copyright (C) 2013 Sterling Graham 
+
+;; Author: Sterling Graham 
+;; URL: http://github.com/sterlingg/json-snatcher
+;; Package-Version: 20150511.2047
+;; Version: 1.0
+;; Package-Requires: ((emacs "24"))
+
+;; This file is not part of GNU Emacs.
+
+;;; Commentary:
+;;
+;; Well this was my first excursion into ELisp programmming.  It didn't go too badly once
+;; I fiddled around with a bunch of the functions.
+;;
+;; The process of getting the path to a JSON value at point starts with
+;; a call to the jsons-print-path function.
+;;
+;; It works by parsing the current buffer into a list of parse tree nodes
+;; if the buffer hasn't already been parsed in the current Emacs session.
+;; While parsing, the region occupied by the node is recorded into the
+;; jsons-parsed-regions hash table as a list.The list contains the location
+;; of the first character occupied by the node, the location of the last
+;; character occupied, and the path to the node.  The parse tree is also stored
+;; in the jsons-parsed list for possible future use.
+;;
+;; Once the buffer has been parsed, the node at point is looked up in the
+;; jsons-curr-region list, which is the list of regions described in the
+;; previous paragraph for the current buffer.  If point is not in one of these
+;; interval ranges nil is returned, otherwise the path to the value is returned
+;; in the form [] for objects, and [] for arrays.
+;; eg: ['value1'][0]['value2'] gets the array at with name value1, then gets the
+;; 0th element of the array (another object), then gets the value at 'value2'.
+;;
+
+;;; Installation:
+;;
+;; IMPORTANT: Works ONLY in Emacs 24 due to the use of the lexical-binding variable.
+;;
+;; To install add the json-snatcher.el file to your load-path, and
+;; add the following lines to your .emacs file:
+;;(require 'json-snatcher)
+;; (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)
+;;
+;; This binds the key to snatch the path to the JSON value to C-c C-g only
+;; when either JS mode, or JS2 mode is active on a buffer ending with
+;; the .json extension.
