Markdown converter

Converts Markdown to a React element. It is based on markdown-it but extends the renderer to provide the following features.

Features

Syntax highlight

This converter uses highlight.js for code block syntax highlighting. To keep the JavaScript bundle file size small, this plugin also includes a custom slide transform which looks for language names in code fences:

```html
<div>HTML</div>
```

Only the highlight definitions for the detected languages are included.

Slide title links

When linking to another slide (via ID (recommended) or slide number), you can omit the link text: [](#/intro). In that case, the title of slide will be used as link text.

Shared links / URLs

The markdown converter uses the references config option passed (by default) to exerslide. This allows you do keep URLs in a single file and use them across multiple slides. All you need to do is use the name / key of the URL.

Example:

references.yml

markdown-it: https://github.com/markdown-it/markdown-it

slide.md

My [markdown parser][markdown-it].

Configuration

You can add plugins to the markdown parser by setting the markdown-converter option of the exerslide config. This is supposed to be a function that gets passed an instance of the markdown parser.

Example:

js/presentation.js

present({
  // ...
  'markdown-converter': function(md) {
    md.use(somePlugin);
  },
});
