Template Functions Bengal provides 80+ template functions and filters organized by category. Functions vs Filters Bengal provides filters (transform values) and functions (standalone operations). Filters use the pipe operator: {{ text | upper }} {{ pages |> where('draft', false) |> sort_by('date') }} Functions are called directly: {{ get_page('docs/about') }} {{ get_data('data/config.json') }} {{ ref('docs/getting-started') }} Tip Tip Quick rule: Transform a value? Use a filter (|). Perform an operation? Use a function (direct call). See Template Functions Reference for complete explanation. Function Categories Category Examples Use For Collection where, sort_by, group_by, limit Querying and filtering pages Navigation get_section, get_breadcrumbs, get_nav_tree Building navigation Linking ref, doc, anchor, relref Cross-references Text truncatewords, slugify, markdownify Text transformations Date time_ago, days_ago, date_iso Date formatting i18n t, current_lang, locale_date Internationalization Quick Examples Filter Pages {% let posts = site.pages |> where('type', 'blog') |> where('draft', false) |> sort_by('date', reverse=true) |> limit(10) %} Build Navigation {% let docs = get_section('docs') %} {% let crumbs = get_breadcrumbs(page) %} Cross-Reference {{ ref('docs/getting-started') }} {{ ref('docs/api', 'API Reference') }} Info Seealso Template Functions Reference — Complete documentation with all parameters and examples Theme Variables Reference — Available template variables (page, site, section) Kida Syntax — Kida template engine syntax
