Handles navigation menu building from config and page frontmatter. Supports incremental menu building with caching, i18n localization, and active state tracking. Menus are built during content discovery and cached for template access. Key Concepts: Menu sources: Config definitions, page frontmatter, section structure Incremental caching: Menu cache invalidation on content changes i18n menus: Localized menu variants per language Active state: Current page and active trail tracking Related Modules: bengal.core.menu: Menu data structures (MenuItem, MenuBuilder) bengal.core.site: Site container that holds menus bengal.rendering.template_functions.navigation: Template access to menus See Also: bengal/orchestration/menu.py: MenuOrchestrator for menu building logic View source 1 Class Classes MenuOrchestrator Orchestrates navigation menu building with incremental caching. Handles menu building from config … 8 Caret Right Orchestrates navigation menu building with incremental caching. Handles menu building from config definitions, page frontmatter, and section structure. Supports incremental menu building by caching menus when config and menu-related pages are unchanged. Creation: Direct instantiation: MenuOrchestrator(site) Created by BuildOrchestrator during build Requires Site instance with pages and config populated Attributes Name Type Description site — Site instance containing menu configuration and pages _menu_cache_key — Cache key for incremental menu building Relationships — Uses: MenuBuilder for menu construction - Uses: MenuItem for menu item representation - Used by: BuildOrchestrator for menu building phase - Updates: site.menu with built menus Thread Safety: Not thread-safe. Should be used from single thread during build. Methods 2 build Build all menus from config and page frontmatter. With incremental building: -… 2 bool Caret Right def build(self, changed_pages: set[Path] | None = None, config_changed: bool = False) -> bool Build all menus from config and page frontmatter. With incremental building: If config unchanged AND no pages with menu frontmatter changed Skip rebuild and reuse cached menus Parameters 2 changed_pages set[Path] | None Set of paths for pages that changed (for incremental builds) config_changed bool Whether config file changed (forces rebuild) Returns bool — True if menus were rebuilt, False if cached menus reused Called during site.build() after content discovery. mark_active Mark active menu items for the current page being rendered. Called during rende… 1 None Caret Right def mark_active(self, current_page: Page) -> None Mark active menu items for the current page being rendered. Called during rendering for each page. Parameters 1 current_page Page Page currently being rendered Internal Methods 6 Caret Right __init__ Initialize menu orchestrator. 1 None Caret Right def __init__(self, site: Site) Initialize menu orchestrator. Parameters 1 site Site Site instance containing menu configuration _can_skip_rebuild Check if menu rebuild can be skipped (incremental optimization). Menus need re… 1 bool Caret Right def _can_skip_rebuild(self, changed_pages: set[Path]) -> bool Check if menu rebuild can be skipped (incremental optimization). Menus need rebuild only if: Config changed (menu definitions) Pages with 'menu' frontmatter changed Parameters 1 changed_pages set[Path] Set of changed page paths Returns bool — True if rebuild can be skipped (menus unchanged) _compute_menu_cache_key Compute cache key for current menu configuration. Key includes: - Menu config … 0 str Caret Right def _compute_menu_cache_key(self) -> str Compute cache key for current menu configuration. Key includes: Menu config from bengal.toml List of pages with menu frontmatter and their menu data Dev params (repo_url) Dev section names (api, cli) that affect dev menu bundling Returns str — SHA256 hash of menu-related data _build_auto_menu_with_dev_bundling Build auto-discovered menu with dev assets bundled into dropdown. This is the … 0 list[dict[str, Any]] Caret Right def _build_auto_menu_with_dev_bundling(self) -> list[dict[str, Any]] Build auto-discovered menu with dev assets bundled into dropdown. This is the single source of truth for auto menu generation. Integrates section discovery, dev bundling, and menu structure in one place. Returns list[dict[str, Any]] — List of menu item dicts ready for MenuBuilder (with deduplication) _find_section_by_name Find a section by its name/slug. 1 Any | None Caret Right def _find_section_by_name(self, section_name: str) -> Any | None Find a section by its name/slug. Parameters 1 section_name str Section name to find (e.g., 'api', 'cli') Returns Any | None — Section object if found, None otherwise _build_full Build all menus from scratch. 0 bool Caret Right def _build_full(self) -> bool Build all menus from scratch. Returns bool — True (menus were rebuilt) ← Previous incremental Next → orchestration List © 2025 Bengal ᓚᘏᗢ window.BENGAL_LAZY_ASSETS = { tabulator: '/bengal/assets/js/tabulator.min.js', dataTable: '/bengal/assets/js/data-table.js', mermaidToolbar: '/bengal/assets/js/mermaid-toolbar.9de5abba.js', mermaidTheme: '/bengal/assets/js/mermaid-theme.344822c5.js', graphMinimap: '/bengal/assets/js/graph-minimap.cc7e42e3.js', graphContextual: '/bengal/assets/js/graph-contextual.440e59c6.js' }; window.BENGAL_ICONS = { close: '/bengal/assets/icons/close.911d4fe1.svg', enlarge: '/bengal/assets/icons/enlarge.652035e5.svg', copy: '/bengal/assets/icons/copy.3d56e945.svg', 'download-svg': '/bengal/assets/icons/download.04f07e1b.svg', 'download-png': '/bengal/assets/icons/image.c34dfd40.svg', 'zoom-in': '/bengal/assets/icons/zoom-in.237b4a83.svg', 'zoom-out': '/bengal/assets/icons/zoom-out.38857c77.svg', reset: '/bengal/assets/icons/reset.d26dba29.svg' }; Arrow Up X -------------------------------------------------------------------------------- Metadata: - Author: lbliii - Word Count: 1605 - Reading Time: 8 minutes
