Read-Eval-Print Loop (REPL) for PHP
===================================

[](#read-eval-print-loop-repl-for-php)

GreenCape REPL is a simple Read-Eval-Print Loop (REPL) written in PHP. It can be combined with arbitrary evaluators for the Eval step.

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

[](#installation)

```
composer require greencape/repl
```

Usage
-----

[](#usage)

Create an Evaluator implementing the `GreenCape\REPL\EvaluatorInterface` and pass it to the REPL:

```
use GreenCape\REPL\EvaluatorInterface;
use GreenCape\REPL\ReadEvalPrintLoop;

class MyEvaluator implements EvaluatorInterface
{
    public function init(): void {}
    public function exit(): void {}
    public function eval(string $input): string
    {
        // Handle the input and return the result
        return $result;
    }
}

$evaluator = new MyEvaluator();
$repl      = new ReadEvalPrintLoop($evaluator);

$repl->run();
```

With `init()` and `exit()` you can implement a setup and teardown for the REPL.

The loop will read your input after a '> ' prompt' and send it to the `eval()` method of the Evaluator. The result will be printed to the console. You can enter multi line input by ending each line with a backslash. Continuation lines are indicated by a '>> ' prompt.

To terminate the loop, enter `exit`.
