RevealJS SVG fragment presenter

SVG fragment builds for reveal.js

Basic use case

make an SVG (maybe in inkscape)
- save it someplace reveal.js can find it (maybe next to your presentation)
- figure out how to identify them (maybe use named layers)
in reveal.js/index.html
- add reveal-svg-fragment.js as a dependency
- in a <section> of reveal.js markup
  - add data-svg-fragment="<url of the someplace>" to something, e.g. a div
  - add some things with class="fragment" inside that thing
    - add title="<a selector>" to those things
      - [*|label=<a label>] is good
      - for more about selectors, check out the W3C page

Example

Let's assume I made an SVG in Inkscape, and saved it next to my index.html. It has three layers: base, fragment1 and fragment2.

<html>
  ...
  <section>
    <div data-svg-fragment="figure.svg#[*|label=base]">
      <a class="fragment" href="[*|label=fragment1]"></a>
      <a class="fragment" href="[*|label=fragment2]"></a>
    </div>
  </section>
  ...
  <script>
    ...
    Reveal.initialize({
      dependencies: [
        ...
        {
          // maybe you put this in `plugins`
          src: 'reveal-svg-fragment.js',
          condition: function(){
            return !!document.querySelector( '[data-svg-fragment]' );
          }
          // Additional options
          // defaults to using already-loaded version, or CDN
          //d3: "./d3.min.js",
          // use a different attribute for your fragment selector
          //selector: "title",
        }
        ...
      ]
    ...
    }
    ...
  </script>
  ...
</html>

LIMITATIONS

won't work in Chrome against file://
- workarounds:
  - dropbox
  - sharepoint
  - confluence
  - gist
  - python -m SimpleHTTPServer
probably won't work in IE
- wontfix
