README

Stub compilation and file generation utilities for building CLI tools and code generators.

📖 Full Documentation | 🐛 Report Issues

✨ Features

• StubCompiler — Replace placeholders in stub templates with dynamic values
• FileWriter — Write files safely with automatic directory creation
• Generator Base — Abstract base class for building custom generators
• Context-Aware Compilation — Built-in support for plugin context tokens

📋 Requirements

🚀 Installation

composer require wpdiggerstudio/wpzylos-cli-core

📖 Quick Start

Basic Stub Compilation

use WPZylos\Framework\Cli\Core\StubCompiler;
use WPZylos\Framework\Cli\Core\FileWriter;

// Create compiler with stubs directory
$compiler = new StubCompiler('/path/to/stubs');

// Compile a stub with replacements
$content = $compiler->compile('controller', [
    'namespace' => 'MyPlugin\\Http\\Controllers',
    'class'     => 'Product',
    'view'      => 'products',
]);

// Write to file
$writer = new FileWriter();
$writer->write('/path/to/ProductController.php', $content);

Plugin Context Compilation

// Compile with plugin-specific tokens
$content = $compiler->compileForPlugin(
    'controller',
    slug: 'my-plugin',
    prefix: 'myplugin_',
    textDomain: 'my-plugin',
    namespace: 'MyPlugin',
    extra: ['class' => 'Product', 'view' => 'products']
);

🏗️ Core Components

StubCompiler

Compiles stub templates by replacing {{token}} placeholders with values.

$compiler = new StubCompiler('/path/to/stubs');

// Set default replacements (applied to all compilations)
$compiler->setDefaults([
    'namespace' => 'MyPlugin',
    'textDomain' => 'my-plugin',
]);

// Compile with additional replacements
$content = $compiler->compile('controller', [
    'class' => 'UserController',
]);

// Get available stub names
$stubs = $compiler->getAvailable(); // ['controller', 'migration', 'request']

Methods:

FileWriter

Safe file writing with automatic directory creation.

$writer = new FileWriter(overwrite: false, dirPermissions: 0755);

// Write file (throws if exists and overwrite is false)
$writer->write('/path/to/File.php', $content);

// Write only if file doesn't exist
$written = $writer->writeIfNotExists('/path/to/File.php', $content);

// Enable overwrite mode
$writer->setOverwrite(true);

Methods:

Generator (Abstract)

Base class for building custom file generators.

use WPZylos\Framework\Cli\Core\Generator;

class ControllerGenerator extends Generator
{
    public function generate(string $name, array $options = []): array
    {
        $className = $this->toClassName($name);

        $content = $this->compiler->compile('controller', [
            'class' => $className,
            'namespace' => $options['namespace'] ?? 'App\\Controllers',
        ]);

        $path = $this->getOutputPath($name);
        $this->writer->write($path, $content);

        return [$path];
    }

    protected function getStubName(): string
    {
        return 'controller';
    }

    protected function getOutputPath(string $name): string
    {
        return $this->basePath . '/app/Http/Controllers/' . $this->toClassName($name) . 'Controller.php';
    }
}

Helper Methods:

📝 Creating Stubs

Stubs are template files with .stub extension using {{token}} placeholders:

<?php
// stubs/service.stub

namespace {{namespace}}\Services;

class {{class}}Service
{
    public function __construct()
    {
        // Service for {{slug}}
    }
}

Common Tokens:

🧪 Testing

# Run all tests
composer test

# Run with coverage
./vendor/bin/phpunit --coverage-html coverage/

🔒 Security

When generating files from user input:

// ✅ Validate class names
$name = preg_replace('/[^a-zA-Z0-9_]/', '', $input);

// ✅ Validate paths
$realPath = realpath($targetDir);
if (!str_starts_with($outputPath, $realPath)) {
    throw new \InvalidArgumentException('Invalid path');
}
