Luar
====

[](#luar)

Luar is a Lua interpreter written in PHP.

Luar implements a reduced version of Lua and also packages some essential Lua libraries. As such Luar offers forward-compatibility with Lua with some minor caveats:

- The math/string libraries use PHP number/string handling; much of the edge-case behaviour has **not** been replicated (e.g. division by zero, integer overflow)
- Not all core functions and libraries are available, but a method is provided to inject your own
- Some language constructs are not implemented (e.g. variable attributes, go-to statements)

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

[](#installation)

```
composer require raudius/luar

```

Usage
-----

[](#usage)

For more details read [the documentation](docs/README.md).

```
$luar = new Luar();
$luar->assign('world', 'Moon');
$luar->assign('hello_world', function ($name='world') {
    return "Hello, $name!";
});

$program = '
    local greeting = hello_world(world)
    print(greeting)

    return greeting
';

$greeting = $luar->eval($program);
```
