Blocks: mdBook Preprocessor for Bootstrap Components

Blocks is an open-source preprocessor for mdbook aimed at integrating Bootstrap components into your mdbook projects. It introduces a custom markdown syntax to include Blocks-specific tags which are converted into Bootstrap-compliant HTML components during the mdbook build process.

Features

• Custom Markdown Syntax: Allows the embedding of Bootstrap components using a simple, readable syntax.
• Integration with mdbook: Designed to operate seamlessly within the mdbook ecosystem.
• Modular Design: Supports the easy addition of new Bootstrap components into the Blocks components library
• Developer Tools: Includes a Visual Studio Code extension for live markdown previewing.

Using Blocks

The Blocks custom markdown syntax is designed to easily incorporate Bootstrap components into mdbook projects. It builds on standard markdown syntax with additional features for declaring components.

To use Blocks, simply wrap your Bootstrap component declarations within [blocks-<component>] tags in your markdown files:

[blocks-card]
title: "Greetings!"
caption: "This is an example of a Blocks card component."
image: "./assets/blocks-watermark.png"
button: "Learn More"
link: "components/cards.md"
[/blocks-card]

Components are specified using tags for the Bootstrap element and attributes for the component's content and settings. Blocks also supports standard markdown within these attributes for enriched text capabilities.

For a detailed list of available components, see the Blocks Component Library.

Visual Studio Code Extension

The Blocks Visual Studio Code extension provides a live preview feature, making it easier to visualize how your markdown will look once transformed into Bootstrap components.
