markdown-it-mdbook

A markdown-it plugin that implements specific features of mdBook

Installation

npm install -D markdown-it-mdbook

Usage

// .vitepress/config.ts
import { defineConfig } from 'vitepress'
import { mdBookPlugin } from 'markdown-it-mdbook'

export default defineConfig({
  markdown: {
    config(md) {
      md.use(mdBookPlugin)
    }
  }
  // ...your configurations
})

The plugin supports the book.toml file, it will be used to configure the mdBook plugin.

Currently, the plugin unsupport to parse the book.toml file directly, you can use the smol-toml to parse toml file and pass the result to the plugin.

For example, you can configure a hidden prefix for a specific language:

const bookOptions = {
  output: {
    html: {
      code: {
        hidelines: { python: "~" }, // Use the `~` as the hidden prefix for Python.
      },
    },
  },
};

md.use(mdBookPlugin, bookOptions)

Including files

If you want to use the including-files feature, you must specify the cwd option in the env parameter when calling the md.render.

Example:

md.render('{{# file.rs}}', { cwd: 'filepath/dir' })

You can also provide a path for resolving the reference file via the getRelatedPath function.

Using Vitepress as an example:

import { type MarkdownEnv } from "vitepress";

export default {
  // ...your other configurations
  markdown: {
    config(md) {
      md.use(mdBookPlugin, {
        getRelatedPath: (env: MarkdownEnv) => {
          const { realPath, path: _path } = env;
          return path.dirname(realPath ?? _path);
        },
      });
    },
  },
}

The cwd will be used to resolve the path of the reference file.

If render content without including-files feature, you can ignore it.

Roadmap

• Hiding code lines
• Rust Playground
• Rust code block attributes
• Including files
• Including portions of a file
• Including a file but initially hiding all except specified lines
• Inserting runnable Rust files
• Controlling page title
• HTML classes provided by mdBook

The features listed above can be viewed in mdBook

Note: The feature list above is not in release order.
