			# ESLint Scope

			ESLint Scope is the [ECMAScript](http://www.ecma-international.org/publications/standards/Ecma-262.htm) scope analyzer used in ESLint. It is a fork of [escope](http://github.com/estools/escope).

			## Usage

			Install:

			```
			npm i eslint-scope --save
			```

			Example:

			```js
			var eslintScope = require('eslint-scope');
			var espree = require('espree');
			var estraverse = require('estraverse');

			var ast = espree.parse(code);
			var scopeManager = eslintScope.analyze(ast);

			var currentScope = scopeManager.acquire(ast); // global scope

			estraverse.traverse(ast, {
			enter: function(node, parent) {
			// do stuff

			if (/Function/.test(node.type)) {
			currentScope = scopeManager.acquire(node); // get current function scope
			}
			},
			leave: function(node, parent) {
			if (/Function/.test(node.type)) {
			currentScope = currentScope.upper; // set to parent scope
			}

			// do stuff
			}
			});
			```
