twigphp/Twig
This system is a modernized PHP template engine that provides a modular architecture for rendering and managing templates. It offers a comprehensive suite of extensions for internationalization, string manipulation, HTML/CSS processing, and caching, alongside a robust security model for sandboxed rendering. The codebase has been refact to use PHP 8 attributes for extension registration, generator-based compilation for memory efficiency, and a new expression parser for improved maintainability.

About this page
- The description of this project is derived from its own commit history, not from its README.
- The score is its highest published measurement, taken on 2 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
- Measured at commit 7793b6153f — the exact code this score is about.
- Scored under rubric rubric-2026.08.18. Score the same commit under that rubric and you get the same number.
