# astw
walk the ast
[](http://ci.testling.com/substack/astw)
[](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)
Return a `walk()` function from the source string or ast object `src`.
## 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
```
