Systopia Symfony ExpressionLanguage Extension
=============================================

[](#systopia-symfony-expressionlanguage-extension)

This is an extension for [Symfony's ExpressionLanguage component](https://symfony.com/doc/current/components/expression_language.html). It provides the functions [date\_create](./src/FunctionProvider/DateCreateExpressionFunctionProvider.php)and [map](./src/FunctionProvider/MapExpressionFunctionProvider.php) as well as different [PHP functions](./src/FunctionProvider/PhpFunctionsFunctionProvider.php). For simplified use all those functions are available in the class [SystopiaExpressionLanguage](./src/SystopiaExpressionLanguage.php).

`date_create` Function
----------------------

[](#date_create-function)

The `date_create` function creates an object of type `\DateTimeImmutable` by using the default constructor.

Example:

```
$expressionLanguage = new SystopiaExpressionLanguage();
$dateTime = $expressionLanguage->evaluate('date_create("2000-01-02 03:04:05")');
```

`map` Function
--------------

[](#map-function)

The function `map` allows to apply an expression to the values of an array (actually any iterable). Each pair of key and value are provided as variables named `key` and `value` to the expression.

Example:

```
$array = [
    'x' => (object) ['a' => 1, 'b' => 2],
    'y' => (object) ['a' => 3, 'b' => 4],
];

$expressionLanguage = new SystopiaExpressionLanguage();
$mapped = $expressionLanguage->evaluate(
    'map(array, "key ~ \": \" ~ (value.a + value.b)")',
     ['array' => $array]
);

var_dump($mapped);
```

Output:

```
array(2) {
  [0]=>
  string(4) "x: 3"
  [1]=>
  string(4) "y: 7"
}

```
