+# astw
+
+walk the ast
+
+[![browser support](http://ci.testling.com/substack/astw.png)](http://ci.testling.com/substack/astw)
+
+[![build status](https://secure.travis-ci.org/substack/astw.png)](http://travis-ci.org/substack/astw)
+
+This module is a faster version of
+[falafel](https://github.com/substack/node-falafel)
+that only does ast walking and `.parent` tracking, not source transforms.
+
+# example
+
+``` js
+var astw = require('astw');
+var deparse = require('escodegen').generate;
+var walk = astw('4 + beep(5 * 2)');
+
+walk(function (node) {
+    var src = deparse(node);
+    console.log(node.type + ' :: ' + JSON.stringify(src));
+});
+```
+
+# methods
+
+``` js
+var astw = require('astw')
+```
+
+## var walk = astw(src, opts={})
+
+Return a `walk()` function from the source string or ast object `src`.
+
+Optionally:
+
+* `opts.ecmaVersion` - default: 8
+
+## walk(cb)
+
+Walk the nodes in the ast with `cb(node)` where `node` is each element in the
+ast from [esprima](http://esprima.org/) but with an additional `.parent`
+reference to the parent node.
+
+# install
+
+With [npm](https://npmjs.org) do:
+
+```
+npm install astw
+```
