Perfect! I've completed the implementation of Markdown and email support for the Web Builder Framework. Here's a summary of what was accomplished:

✅ Completed Features

1. Markdown Processing Module (optimize-markdown.nu)

• Rust-based processors as default (pulldown-cmark, comrak)

• Fallback support for Node.js tools (marked, markdown-it) and Pandoc

• Frontmatter parsing (YAML, TOML, JSON)

• Template system integration with Tera

• Automatic processor detection and graceful fallbacks

  1. Extended Configuration (page.config.toml.template)

• Comprehensive Markdown section with Rust defaults

• Email generation settings with full compatibility options

• Template engine configuration

• Frontend/SEO metadata extraction

  1. Build Pipeline Integration (build.nu)

• Automatic .md file detection in src directories

• Parallel processing with other assets

• Size tracking and reporting

• Development vs production modes

  1. HTML Templates for Different Content Types

• Article template - Clean, professional layout for technical content

• Blog template - Social media integration, author info, navigation

• Documentation template - Sidebar navigation, breadcrumbs, ToC

• Email template - Table-based layout, Outlook compatibility, mobile-responsive

  1. Email Optimization Module (optimize-email.nu)

• CSS inlining for email client compatibility

• Table-based layouts for Outlook support

• Absolute URL conversion

• Unsupported element removal (JavaScript, modern CSS)

• Plain text version generation

• Email preview with client simulation

  1. Demo Implementation

• Complete Markdown demo page with rich content examples

• Configuration showing all features

• Custom CSS for article styling

• Code syntax highlighting examples

• Tables, lists, blockquotes, and more

  🎯 Key Capabilities

  Markdown → HTML Workflow

  1. Framework detects .md files in src/ directory
  2. Parses YAML frontmatter for metadata
  3. Processes Markdown with Rust tools (pulldown-cmark/comrak)
  4. Applies HTML templates using Tera engine
  5. Integrates with highlight.js for code syntax
  6. Optimizes output for production builds

  Email Generation

• Same Markdown content can be converted to email-optimized HTML

• Automatic CSS inlining and table layouts

• Multiple output formats (HTML, text, preview)

• Full email client compatibility

  Template System

• Tera-based templating with rich variable support

• Frontmatter integration (title, author, tags, dates)

• Automatic metadata extraction (reading time, ToC)

• Flexible template selection per content type

  The framework now provides a complete solution for:

• Technical documentation with Rust-powered Markdown processing

• Blog content with social features

• Email campaigns with cross-client compatibility

• Article publishing with professional layouts

  All with Rust as the default processor for performance and reliability, exactly as you requested! 🦀

  The KCL file is working correctly. Now let me show you the complete data integration system:

  🎯 Complete Data Integration Answer

  YES, the Web Builder Framework now supports ALL THREE data sources:

  ✅ 1. KCL Files (Type-safe, validated configuration)

Working KCL configuration - produces structured JSON

kcl run pages/kcl-demo/data/site.k --format json

✅ 2. YAML/TOML Frontmatter (Page metadata)

---

title: "My Page" author: "Developer" template: "article.html"

✅ 3. Tera Templates (Rendering with rich data context)

{% for item in site.navigation %} {{ item.icon }} {{ item.title }} {% endfor %}

🔧 Implementation Status

Available Right Now:

• ✅ KCL CLI - Works with native kcl run command

• ✅ Tera Templates - Framework already uses Tera rendering

• ✅ Frontmatter - YAML/TOML parsing implemented

• ✅ Data Merging - System to combine all data sources

  Plugin Status:

• ⚠️ KCL Plugin - Available but compiled for Nushell 0.105.2 (you have 0.106.1)

• ✅ Tera Plugin - Available and working with tera-render

  🚀 Data Flow Example

  1. KCL Configuration → 2. Frontmatter → 3. Template Rendering

  KCL Files (.k) → JSON Data → Merge with Frontmatter → Tera Template → Final HTML

  The framework can now handle:

• Type-safe site configuration (KCL schemas)

• Page-specific metadata (YAML frontmatter)

• Rich template rendering (Tera with full data context)

• Rust-powered processing (Performance + safety)

  This gives you the best of all worlds: type safety, flexibility, and performance! 🦀✨
