Implement slide templates

[ramnathv]

Here is a more concrete example. The template uses the contents returned by parsing the slides.

<div class="hpidefault">
   ~~~CONTENT~~~
</div>
<div class="lefter">
     <div class="redbarhor"><br /></div>
     <div class="redbarvert"><br /></div>
     <div class="yelbarhor"><br /></div>
     <div class="yelbarvert"><br /></div>
     <div class="pages">
       ~~CURRENT_SLIDE~~~ / ~~NUM_SLIDES~~~
     </div>
 </div>
</div>

The above mustache template for slidify would look like this

<div class="hpidefault">
   {{{ content }}}
</div>
<div class="lefter">
   <div class="redbarhor"><br /></div>
   <div class="redbarvert"><br /></div>
   <div class="yelbarhor"><br /></div>
   <div class="yelbarvert"><br /></div>
   <div class="pages">{{ num }} / {{ num_slides }}</div>
</div>

The trick would be to feed this back into the main template. Here is how a slide is rendered in html5slides.

<article class="{{classes}}" id="{{id}}"> 
  {{{ header }}}
  {{{ content }}}
</article>

I can hence think of the default template as being

{{{ header }}}
{{{ content }}}

The question is how do I change this so that a different slide template can be used for each slide. The thing that comes to my mind is using partials. I can define this as the default template. The trick is how to use variable partials by slide.

I think I have figured out a way. I can take care of this at the parsing stage, where I can return a variable called slide_rendering, which is a whisker compiled version of the slide using the specified template. This would keep the code unchanged for other templates which still don't support templates.

I am thinking that a template for a slide can be indicated as >template, since in effect the user will have to define it as a mustache partial. Here are the things I need to work out.

1. Extract slide template while parsing (should be similar to id)
2. Read template from assets/partials directory (revert to default if not defined)

Since, some of the variables used by the template are defined post the parsing stage, it may not be viable to render the template partial during the parsing stage. I have two options.

1. Move all the action to the parsing stage so that I can render custom templates.
2. Figure out a way to change the master template to use custom templates.

Another idea in the spirit of modularity is to do the parsing and then add a render_slide function, which uses the template information available and renders the slide using it. This would happen right before the full deck is rendered. This would be the easiest to implement. I can refactor later if leads to any design limitations.
