```


# API

```


## `udebug(code, opts)`

Remove [visionmedia/debug](https://github.com/visionmedia/debug) related code from `code` using AST.

<dl>
  <dt>
    <code>code</code> : <code>string</code>
  </dt>
  <dd>
    target code
  </dd>

  <dt>
    <code>opts.filepath</code> : <code>string</code>
  </dt>
  <dd>
    filepath to attach source map
  </dd>

  <dt>
    <code>opts.debug</code> : <code>boolean</code>
  </dt>
  <dd>
    attach source map or not
  </dd>
</dl>


# Example
```js
var udebug = require('udebug')

var code = [
  'var debug = require("debug"),',
  '    d     = debug("MYAPP")   ',
  '                             ',
  'function greet() {           ',
  '  d("#greet called")         ',
  '  return "hi"                ',
  '}                            '
].join('\n')

process.stdout.write(udebug(code, {filepath: 'a.js', debug: true}))
```

will output:

```js
function greet() {
    return 'hi';
}
