Plugin for the [XP Compiler](https://github.com/xp-framework/compiler/) which adds an `~` infix operator to the PHP language.

Examples
--------

[](#examples)

The pattern operator treats the following expression as a regular expression and returns the matches it generates:

```
if ($greeting ~ '/^H[ea]llo/') {
  // Matches!
}

if ($matches= $greeting ~ '/^H[ea]llo/') {
  // Work with $matches
}
```

The pattern is passed to [preg\_match](https://www.php.net/preg_match), so the above is equivalent of writing the following:

```
if (preg_match($greeting, '/^H[ea]llo/')) {
  // Matches!
}

if (preg_match($greeting, '/^H[ea]llo/', $matches)) {
  // Work with $matches
}
```

Installation
------------

[](#installation)

After installing the XP Compiler into your project, also include this plugin.

```
$ composer require xp-framework/compiler
# ...

$ composer require xp-lang/php-pattern-operator
# ...
```

No further action is required.
