vm-browserify
=============
Emulate node's vm module for the browser.
example
=======
Just write some client-side javascript:
``` js
var vm = require('vm');
$(function () {
var res = vm.runInNewContext('a + 5', { a : 100 });
$('#res').text(res);
});
```
compile it with [browserify](http://github.com/substack/node-browserify):
```
browserify entry.js -o bundle.js
```
then whip up some html:
``` html
result =
```
and when you load the page you should see:
```
result = 105
```
methods
=======
vm.runInNewContext(code, context={})
------------------------------------
Evaluate some `code` in a new iframe with a `context`.
Contexts are like wrapping your code in a `with()` except slightly less terrible
because the code is sandboxed into a new iframe.
browser compatability
=====================
All modern browsers are supported.
If you have a [browserling](http://browserling.com) account,
from the testling/ directory just do:
```
$ ./test.sh substack@gmail.com
Enter host password for user 'substack@gmail.com':
chrome/17.0:
vmRunInNewContext ................................. 5/5
iexplore/9.0:
vmRunInNewContext ................................. 5/5
firefox/10.0:
vmRunInNewContext ................................. 5/5
safari/5.1:
vmRunInNewContext ................................. 5/5
opera/11.6:
vmRunInNewContext ................................. 5/5
total ............................................... 25/25
```
In IE8 and IE7, running `vm.runInNewContext()` more than once can cause the
browsers to hang for some reason. Otherwise they work too.
install
=======
This module is depended upon by browserify, so you should just be able to
`require('vm')` and it will just work. However if you want to use this module
directly you can install it with [npm](http://npmjs.org):
```
npm install vm-browserify
```
