ScriptLite C Extension
======================

[](#scriptlite-c-extension)

> **Mirror repository** — this repo is automatically mirrored from [aheinze/ScriptLite](https://github.com/aheinze/ScriptLite) for PHP PIE installation. All development, issues, and pull requests happen in the [main repository](https://github.com/aheinze/ScriptLite).

High-performance PHP extension for the [ScriptLite](https://github.com/aheinze/ScriptLite) ECMAScript interpreter. Replaces the PHP bytecode VM with a C implementation using computed-goto dispatch, delivering ~180x speedup.

The extension ships with a native C parser only (no PHP parser fallback), so no Composer autoloader or external PHP parser runtime is required at runtime.

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

[](#installation)

### Via PHP PIE (recommended)

[](#via-php-pie-recommended)

```
pie install aheinze/scriptlite-ext
```

### Manual build

[](#manual-build)

Prerequisites: PHP 8.3+ dev headers, `phpize`, C11 compiler, `libpcre2-dev`, `make`.

```
phpize
./configure --enable-scriptlite
make -j"$(nproc)"
make install
```

Then enable:

```
extension=scriptlite
```

Verify
------

[](#verify)

```
php -r "var_dump(extension_loaded('scriptlite'));"
# bool(true)

php -r "echo (new ScriptLiteExt\Engine())->eval('1 + 2');"
# 3
```

Usage
-----

[](#usage)

### Standalone (no PHP library needed)

[](#standalone-no-php-library-needed)

```
$engine = new ScriptLiteExt\Engine();
$result = $engine->eval('Math.max(1, 2, 3)');
echo $result; // 3
```

### With ScriptLite PHP library

[](#with-scriptlite-php-library)

When installed alongside `aheinze/ScriptLite`, the PHP `Engine` class automatically delegates to the C extension — no code changes needed.

```
$engine = new ScriptLite\Engine();
$result = $engine->eval('Math.max(1, 2, 3)'); // uses C extension transparently
```
