Code.Movie plugin for reveal.js

Integrate animated, syntax highlighted code from Code.Movie into your reveal.js presentations!

What this does

This plugin makes Reveal.js handle each animation keyframe like a fragment. You can navigate through an animated code sample using arrow keys or a remote, just like you would navigate through slides or regular fragments.

How to use

You can install the library as @codemovie/code-movie-reveal-plugin from NPM, download the latest release from GitHub or just grab either index.esm.js or index.js from the source code.

Then create a Reveal.js slide deck and import the plugin just like any other reveal.js plugin:

<!-- Using the plugin as a module -->
<script src="dist/reveal.js"></script>
<script type="module">
  import { CodeMovie } from "./plugin/code-movie/index.esm.js";
  Reveal.initialize({
    hash: true,
    plugins: [CodeMovie]
  });
</script>

<!-- Using the module as a plain script -->
<script src="dist/reveal.js"></script>
<script src="plugin/code-movie/index.esm.js"></script>
<script>
  Reveal.initialize({
    hash: true,
    plugins: [CodeMovie]
  });
</script>

Then either export your Code.Movie project to HTML or get an embed code. Add the exported HTML or the embed code to a slide:

<!-- A slide with the HTML export of a Code.Movie project -->
<section>
  <code-movie-runtime keyframes="0 1 2 3 4 5">
    <!-- Exported HTML content -->
  </code-movie-runtime>
</section>

And that's basically it! You can tweak details like the font size by setting the appropriate attributes on either the <code-movie-runtime> element or the <script> element containing the runtime code.

<!-- Setting the font size on an HTML export -->
<section>
  <code-movie-runtime keyframes="0 1 2 3 4 5" style="font-size:0.375em">
    <!-- Exported HTML content -->
  </code-movie-runtime>
</section>

The plugin bundles the <code-movie-runtime> element, so everything should work out of the box.

How this works

This plugin adds an invisible fragment for each keyframe or each <code-movie-runtime> in the presentation and performs a bit of event handling to tie the animation's state to the current fragment. It is extremely simple and basic :)
