This little script allow you to "preview" your internal links, using the TippyJS Library, ala Wikipedia hovering, or like in Obsidian, for a material mkdocs wiki.

Its allow :

• Pop-hover footnote ;
• Link directly a preview of a part of the text using an anchor (title)
• Preview the entire file

Note : Link a particular part of the text doesn't work (ie it doesn't support Obsidian block-id). You need to link a title or a footnote.

Some preview :

First, you need to add wiki_hover.js & tippy.css in your assets (assets/js & assets/css) and edit your mkdocs.yml according :

extra_javascript:
  - assets/js/wiki_hover.js
extra_css:
  - assets/css/tippy.css

The second steps is to override your main.html. For more information about overriding template, check the material Mkdocs documentation.

So, you need :

1. To create an overrides folder
2. Add it to your mkdocs.yml in theme[custom_dir] as follow :

   theme:
   	name: 'material'
   	# keep the other things here !
       custom_dir: overrides

3. Create a main.html in overrides, with adding this contents :

{% extends "base.html" %}

{% block extrahead %}
  <script src="https://unpkg.com/@popperjs/core@2/dist/umd/popper.min.js"></script>
  <script src="https://unpkg.com/tippy.js@6/dist/tippy-bundle.umd.js"></script>
  <link rel="stylesheet" href="https://unpkg.com/tippy.js@6/animations/scale-subtle.css"/>
  <link rel="stylesheet" href="https://unpkg.com/tippy.js@6/themes/translucent.css"/>
{% endblock %}

Now, normally, your good !
