### sourceMap

Type: `boolean`  
Default: `false`

Generates a source map (nodes should contain positions in `loc` property). Note, that an object instead of string is returned in that case.

```js
var ast = csstree.parse('.test { color: red }', {
    filename: 'my.css',
    positions: true
});

var result = csstree.generate(ast, { sourceMap: true });
// { css: '.test{color:red}', map: SourceMapGenerator {} }
```

### decorator

Type: `function`  
Default: none

A function that a handlers used by a generator. TBD
