mdBook-pagetoc

A page table of contents for mdBook

What is this?

On 23rd June, I opened an issue for mdBook to add a table of contents for individual pages here. After some time, I noticed that there had been no response to the issue and decided to do something about it.

I don't know Rust and have very little experience in web development, but could not stand to not have this features any longer.

A sample of it in action can be viewed here.

How do I use it?

1. Copy these files to the theme directory in your mdBook.

   • theme/pagetoc.js, which handles the scrolling and clicking for the table of contents

   • theme/pagetoc.css which handles the styling

   • theme/index.hbs, which updates <main>

     <main>
         <div class="content-wrap">
             {{{ content }}}
         </div>
         <div class="sidetoc">
             <nav class="pagetoc"></nav>
         </div>
     </main>

2. Add the following to your book.toml file:

[output.html]
additional-css = ["theme/pagetoc.css"]
additional-js = ["theme/pagetoc.js"]

1. If you're still stuck, don't worry - this entire repository is an example of it working in action!
