URL External Open LLM text Copy Copy LLM text Share with AI Ask Claude Ask ChatGPT Ask Gemini Ask Copilot Module rendering.template_functions.icons Template functions for rendering SVG icons. Provides optimized icon rendering functions for use in Jinja2 templates. Icons are pre-loaded at registration time and rendered output is cached by (name, size, css_class, aria_label) to minimize per-render overhead. Performance: All icons pre-loaded at template engine initialization (~86 icons, ~50KB) Rendered SVG cached by parameters (typical hit rate: >95%) Regex processing only on cache miss Zero file I/O during template rendering View source 8 Functions Functions _get_icons_directory Get the icons directory from the default theme. 0 Path Caret Right def _get_icons_directory() -> Path Get the icons directory from the default theme. Returns Path _preload_all_icons Pre-load all icons into memory at startup. Called once during template engine initialization. Load… 0 None Caret Right def _preload_all_icons() -> None Pre-load all icons into memory at startup. Called once during template engine initialization. Loads all SVG files from the icons directory into the _preloaded_icons cache. _escape_attr Escape HTML attribute value. 1 str Caret Right def _escape_attr(value: str) -> str Escape HTML attribute value. Parameters 1 Name Type Default Description value str — Returns str _render_icon_cached Render an icon with LRU caching for repeated calls. The cache key is (name, size, css_class, aria_… 4 str Caret Right def _render_icon_cached(name: str, size: int, css_class: str, aria_label: str) -> str Render an icon with LRU caching for repeated calls. The cache key is (name, size, css_class, aria_label). This captures the vast majority of repeated icon renders (e.g., navigation icons appear on every page with the same parameters). Parameters 4 Name Type Default Description name str — Icon name (already mapped through ICON_MAP) size int — Icon size in pixels css_class str — Additional CSS classes aria_label str — Accessibility label Returns str — Rendered SVG HTML string, or empty string if icon not found icon Render an SVG icon for use in templates. Uses pre-loaded icons and LRU caching for optimal perform… 4 Markup Caret Right def icon(name: str, size: int = 24, css_class: str = '', aria_label: str = '') -> Markup Render an SVG icon for use in templates. Uses pre-loaded icons and LRU caching for optimal performance. Icons are loaded once at startup and rendered output is cached by (name, size, css_class, aria_label) to minimize repeated work. Icon name mapping priority: theme.yaml aliases (if theme config available) ICON_MAP (fallback for backwards compatibility) Parameters 4 Name Type Default Description name str — Icon name (e.g., "search", "menu", "close", "arrow-up") size int 24 Icon size in pixels (default: 24) css_class str '' Additional CSS classes aria_label str '' Accessibility label (if empty, uses aria-hidden) Returns Markup — Markup object containing inline SVG HTML, or empty Markup if icon not found register Register icon template functions and pre-load all icons. Pre-loads all SVG icons into memory at re… 2 None Caret Right def register(env: Environment, site: Site) -> None Register icon template functions and pre-load all icons. Pre-loads all SVG icons into memory at registration time for optimal render performance. Icons are typically ~50KB total. Parameters 2 Name Type Default Description env Environment — Jinja2 environment site Site — Site instance (stored for theme config access) get_icon_cache_stats Get icon cache statistics for debugging/profiling. 0 dict[str, int] Caret Right def get_icon_cache_stats() -> dict[str, int] Get icon cache statistics for debugging/profiling. Returns dict[str, int] — Dictionary with cache hit/miss information clear_icon_cache Clear the icon render cache. Useful for testing or when icons are modified during development. 0 None Caret Right def clear_icon_cache() -> None Clear the icon render cache. Useful for testing or when icons are modified during development. ← Previous i18n Next → images 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: 1507 - Reading Time: 8 minutes
