Usage
=====

[](#usage)

Regex-Builder allows you to build regular expressions in a fluent object-oriented way.

The following example shows how to build a regular expression.

```
$pattern = new \Flexic\RegexBuilder\Pattern();

$pattern->add(
    new \Flexic\RegexBuilder\Expr\Group([
        new \Flexic\RegexBuilder\Expr\LookAround\Ahead(
            new \Flexic\RegexBuilder\Expr\Enclosed(
                new \Flexic\RegexBuilder\Expr\Literal(''),
            ),
        ),
        new \Flexic\RegexBuilder\Expr\Enclosed(
            new \Flexic\RegexBuilder\Expr\Option([
                new \Flexic\RegexBuilder\Expr\Marker\AnyWord(),
                new \Flexic\RegexBuilder\Expr\Marker\AnyNonWord(),
            ]),
        ),
        new \Flexic\RegexBuilder\Expr\LookAround\Follow(
            new \Flexic\RegexBuilder\Expr\Literal(''),
        ),
    ]),
);
```

Patterns build with Regex-Builder can be converted to a string representation of a regular expression.

```
$pattern->toString(); // returns: '(?=(\))(\w|\W)(?
