Remove unintended `Beobles\` namespace prefix from View engine by Copilot · Pull Request #6 · beobles/php-template-engine

Copilot · 2026-06-03T00:23:29Z

The namespace migration introduced an unintended Beobles\ prefix in the template engine classes. This PR aligns all affected references back to the repository’s namespace convention (Core\View\...) to restore consistent class resolution.

Namespace normalization across source
- Replaced Beobles\Core\View\... with Core\View\... in src/Core/View/** namespaces and imports.
- Updated generated compiled-template header namespace/imports in Compiler::generateHeader() to emit Core\View\Compiled.
Autoload alignment
- Updated the PSR-4 prefix in autoload.php from Beobles\Core\View\ to Core\View\.
Usage/docs consistency
- Updated consumer-facing references (example and README) to import Core\View\Engine.

// Before
use Beobles\Core\View\Engine;

// After
use Core\View\Engine;

Original prompt

🚀 Professional Template Rendering - Remove eval(), Implement File-Based Compilation

Problema Atual

Seu Renderer usa eval() - inseguro, lento, não debugável, unprofessional.

// ❌ ERRADO (eval):
eval('?>' . $compiledCode);

Solução: Twig/Laravel Pattern

Como funciona em Twig/Laravel:

Compilar template → PHP válido
Escrever em arquivo no cache directory
Include com namespace isolado (não eval)
Versionamento & invalidação inteligentes
Stack traces corretos para debugging

Estrutura de Cache

cache/
├── 5a8f3d2e1c4b9f7a.php          # Compiled template
├── 5a8f3d2e1c4b9f7a.meta         # Metadata (path, hash, deps)
└── manifest.json                  # Version tracking

Arquivo Compilado Exemplo

<?php
// cache/5a8f3d2e1c4b9f7a.php

namespace Core\View\Compiled;

use Core\View\Engine;

/**
 * Compiled from: templates/Home/Home.html
 * Compiled at: 2026-06-02 21:19:23
 * Hash: sha256:abc123...
 */
class TemplateAbc123 
{
    public function render(array $data = [], Engine $engine = null): string
    {
        $output = '';
        
        // Inject scope
        foreach ($data as $__name => $__value) {
            $$__name = $__value;
        }
        
        $output .= '<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>';
        $output .= $engine->escape($title ?? "", 'html');
        $output .= '</title>
</head>
<body>
    
</body>
</html>';
        
        return $output;
    }
}

Invocação

// Renderer apenas faz include + method call
$class = require $cacheFile; // Returns class path
$template = new $class();
return $template->render($data, $engine);

Implementação Completa

1. CompiledTemplate Base Class

<?php
// src/Core/View/CompiledTemplate.php

namespace Core\View;

abstract class CompiledTemplate
{
    abstract public function render(array $data = [], Engine $engine = null): string;
    
    protected function escape(mixed $value, string $context = 'html'): string
    {
        if ($engine === null) {
            return (string)$value;
        }
        return $engine->escape($value, $context);
    }
}

2. Compiler - Generate Class-Based Code

<?php
// src/Core/View/Compiler.php

namespace Core\View;

class Compiler
{
    private string $className;
    private string $sourceFile;
    
    public function compile(array $nodes, string $sourceFile = ''): string
    {
        $this->sourceFile = $sourceFile;
        $this->className = 'Template' . hash('crc32', $sourceFile);
        
        $code = $this->generateHeader();
        $code .= $this->generateClassStart();
        $code .= $this->generateRenderMethod($nodes);
        $code .= $this->generateClassEnd();
        
        return $code;
    }
    
    private function generateHeader(): string
    {
        return <<<'PHP'
<?php

namespace Core\View\Compiled;

use Core\View\Engine;
use Core\View\CompiledTemplate;

/**
 * Auto-generated compiled template
 * Source: {source}
 * Generated: {date}
 */
PHP . sprintf(
            "\n * Source: %s\n * Generated: %s\n */\n\n",
            $this->sourceFile,
            date('Y-m-d H:i:s')
        );
    }
    
    private function generateClassStart(): string
    {
        return <<<PHP
class {$this->className} extends CompiledTemplate
{
    private Engine \$__engine;
    
    public function render(array \$data = [], Engine \$engine = null): string
    {
        \$this->__engine = \$engine;
        \$output = '';
        
        // Inject data into scope
        extract(\$data, EXTR_SKIP);
        
PHP;
    }
    
    private function generateRenderMethod(array $nodes): string
    {
        $code = '';
        
        foreach ($nodes as $node) {
            $code .= $this->compileNode($node);
        }
        
        return $code;
    }
    
    private function generateClassEnd(): string
    {
        return <<<'PHP'

        return $output;
    }
}

PHP;
    }
    
    private function compileNode(object $node): string
    {
        $class = (new \ReflectionClass($node))->getShortName();
        
        return match ($class) {
            'TextNode' => $this->compileText($node),
            'ExpressionNode' => $this->compileExpression($node),
            'RawNode' => $this->compileRaw($node),
            'ComponentNode' => $this->compileComponent($node),
            'IfNode' => $this->compileIf($node),
            'ForeachNode' => $this->compileForeach($node),
            'BlockNode' => $this->compileBlock($node),
            default => ''
        };
    }
    
    private function compileText(object $node): string
    {
        $escaped = addslashes($node->value);
        return "\$output .= '{$escaped}';\n";
    }
    
    private function compileExpression(object $node): string
    {
        $expr = $this->transformExpression($node->value);
   ...
