+ +``` + +## Performance + +The new system provides significant performance improvements: + +- **Template compilation**: Twig compiles templates to optimized PHP code +- **Intelligent caching**: Only recompiles when source templates change +- **Memory efficiency**: Reduced memory usage compared to legacy system +- **Faster rendering**: Compiled templates execute faster than interpreted ones + +## Future Enhancements + +Planned improvements include: + +1. **Template inheritance**: Use Twig's `{% extends %}` for better template organization +2. **Macro system**: Reusable template components +3. **Advanced filters**: More built-in filters for common operations +4. **IDE support**: Better syntax highlighting and auto-completion +5. **Asset management**: Integration with modern asset pipelines + +## Conclusion + +The new Template system provides a modern, powerful foundation while preserving complete backward compatibility. Developers can continue using existing code while gradually adopting new features as needed. \ No newline at end of file diff --git a/src/Template/Template.php b/src/Template/Template.php new file mode 100644 index 000000000..590ebafed --- /dev/null +++ b/src/Template/Template.php @@ -0,0 +1,472 @@ + [ + 0 => [] + ] + ]; + + public array $vars = []; + public array $files = []; + public array $files_cache = []; + public array $files_cache2 = []; + public string $root = ''; + public string $cachedir = ''; + public string $tpldir = ''; + public string $tpldef = 'default'; + public int $use_cache = 1; + public string $tpl = ''; + public string $cur_tpl = ''; + public array $replace = []; + public string $preparse = ''; + public string $postparse = ''; + public array $style_config = []; + public array $lang = []; + public array $uncompiled_code = []; + + /** + * Private constructor for singleton pattern + */ + private function __construct(string $root = '.') + { + global $lang; + + // Initialize backward compatibility properties + $this->vars =& $this->_tpldata['.'][0]; + $this->tpldir = TEMPLATES_DIR; + $this->root = $root; + $this->tpl = basename($root); + $this->lang =& $lang; + $this->use_cache = config()->get('xs_use_cache'); + $this->cachedir = CACHE_DIR .
