+
+Detect global variables in JavaScript using acorn
+
+[Get supported acorn-globals with the Tidelift Subscription](https://tidelift.com/subscription/pkg/npm-acorn_globals?utm_source=npm-acorn-globals&utm_medium=referral&utm_campaign=readme)
+
+[![Build Status](https://img.shields.io/travis/ForbesLindesay/acorn-globals/master.svg)](https://travis-ci.org/ForbesLindesay/acorn-globals)
+[![Dependency Status](https://img.shields.io/david/ForbesLindesay/acorn-globals.svg)](https://david-dm.org/ForbesLindesay/acorn-globals)
+[![NPM version](https://img.shields.io/npm/v/acorn-globals.svg)](https://www.npmjs.org/package/acorn-globals)
+
+## Installation
+
+    npm install acorn-globals
+
+## Usage
+
+detect.js
+
+```js
+var fs = require('fs');
+var detect = require('acorn-globals');
+
+var src = fs.readFileSync(__dirname + '/input.js', 'utf8');
+
+var scope = detect(src);
+console.dir(scope);
+```
+
+input.js
+
+```js
+var x = 5;
+var y = 3, z = 2;
+
+w.foo();
+w = 2;
+
+RAWR=444;
+RAWR.foo();
+
+BLARG=3;
+
+foo(function () {
+    var BAR = 3;
+    process.nextTick(function (ZZZZZZZZZZZZ) {
+        console.log('beep boop');
+        var xyz = 4;
+        x += 10;
+        x.zzzzzz;
+        ZZZ=6;
+    });
+    function doom () {
+    }
+    ZZZ.foo();
+
+});
+
+console.log(xyz);
+```
+
+output:
+
+```
+$ node example/detect.js
+[ { name: 'BLARG', nodes: [ [Object] ] },
+  { name: 'RAWR', nodes: [ [Object], [Object] ] },
+  { name: 'ZZZ', nodes: [ [Object], [Object] ] },
+  { name: 'console', nodes: [ [Object], [Object] ] },
+  { name: 'foo', nodes: [ [Object] ] },
+  { name: 'process', nodes: [ [Object] ] },
+  { name: 'w', nodes: [ [Object], [Object] ] },
+  { name: 'xyz', nodes: [ [Object] ] } ]
