To make loading of extras/ addons simpler, and remove cruft from presentation html files, I created a new plugin src/plugins/extras/. If any of the extra addons (highlight.js, markdown.js, mathjax.js or mermaid.js) are added to the html file with a regular <script> tag, then this module will discover and know how to init the module for you, so it is not necessary to do that in html. If you're not using the extras, this plugin does nothing. Note that in the branch history where you are reading this commit, the extras/ directory doesn't actually exist yet, nor do the examples/ that use them. But they will hopefully join this branch soon.
Extras Plugin
The Extras plugin will initialize the optional addon plugins from extras/ directory, if they were loaded.
Generally, for an extras plugin to have been loaded, 2 things must have happened:
- The extras plugins must be present in extras/ directory, for example after
running
git submodule update - One or more extras plugins are added to the impress.js presentation (the HTML
file) by the author using a regular
<script>tag.
If one or more extras plugins were so added, this plugin will automatically
discover them and perform initialization (such as calling
mermaid.initialize()).
If no extras plugins are added to a presentation, this plugin does nothing.
Note that some extra plugins (like mathjax) initialize themselves immediately, and there's nothing to do here.
