json_merger/indicators.js

Merge JSON with indicators such as @override, @match, @delete and @insert to tell the processor how to merge the files.

var indicators = {
	// root indicators
	EXTENDS: '@extends',

	// used for array, append to end, prepend to beginning, or insert at index:
	APPEND: '@append',
	PREPEND: '@prepend',
	INSERT: '@insert',

	// @move is the same as @insert but used with @match
	MOVE: '@move',

	// Used with match so that we can match primitives:
	//   To match the c value in this array (index 2): ["a", "b", "c"] use @match: "[@value=c]"
	ATTR_VALUE: '@value',

	// Remap value og the object to whats in @value (usefull for appending / prepending to arrays)
	VALUE: '@value',
	OVERRIDE: '@override',
	COMMENT: '@comment',
	ID: '@id',
	DELETE: '@delete',
	MATCH: '@match'
