Foehn is a development framework designed for developers building custom themes and plugins. It uses PHP 8 attributes to automatically discover and register various site components, which organizes code and reduces boilerplate setup.

• Attribute-Based Auto-Discovery: Define hooks, custom post types, taxonomies, ACF blocks, and REST API routes using PHP attributes. The framework automatically finds and registers these classes, eliminating the need for manual function calls in a central file.
• Structured Component Development: Build features like ACF blocks and Gutenberg blocks as dedicated classes. These classes support dependency injection, typed data transfer objects (DTOs) for template context, and clear separation of logic, fields, and rendering.
• Template and Context Management: Use context providers to inject specific data into templates and template controllers to manage rendering logic. This provides a structured way to prepare data for views without cluttering template files.
• Integrated Development Tools: Includes WP-CLI commands for generating code scaffolds like blocks and post types, and for managing the auto-discovery cache. This speeds up development and maintains consistency across projects.
• Modern PHP Foundation: Built for PHP 8.5+ and integrates with the Tempest framework for its dependency injection container, promoting a clean, object-oriented architecture for site development.
