	if (issues.length > 0) {
		issues.forEach(function (issue) {
			fancyLog(colors.cyan('[gulp-htmllint] ') + colors.white(filepath + ' [' + issue.line + ',' + issue.column + ']: ') + colors.red('(' + issue.code + ') ' + issue.msg));

### Options

#### options.config

### Custom Reporter

The custom reporter is a function which accepts 2 parameters: filepath and an array of issues as returned by the htmlling-plugin.

## Results

Add the property htmllint to the file object, which is available to streams that follow the htmllint stream. The property htmllint has the following format:

```js
{
	"success": false, // or true for passing htmllint successfully
	"issues": [] // an array of issues as returned by htmllint
}
```
