S9 is a tool written in Ruby

• Converts Markdown into a web presentation
• Requires FullerScreen
• https://addons.mozilla.org/en-US/firefox/addon/4650
• See http://slideshow.rubyforge.org/

...but not so excited about Ruby

Let's do the same in Sputnik

(But kudos to S9 for showing us the way!)

1. Look at the HTML generated by S9
2. Turn it into a Cosmo template
3. Save it to http://sputnik.freewisdom.org/en/_templates_for_s9
   • set "prototype" to "@Lua_Config"

The only complicated part is the $do_slides:

$do_slides[=[
 <div class='slide'>
  <h1>$heading</h1>
  $content
 </div>
]=]

We'll also need an "action".

It's simple: most of the work is done by markdown

module(..., package.seeall)

actions = {}
actions.slides = function(node, request, sputnik)
   require"markdown"
   local delim = "@@@@@@@@@@"
   local html = ("\n"..node.markup.transform(node.content).."<h2>"):gsub("<h2>", "\n"..delim.."\n<h2>").."\n"..delim
   return cosmo.f(node.templates.SLIDESHOW){
      title = node.title,
      do_slides = function()
                     for heading, content in html:gmatch("\n<h2>(.-)</h2>(.-)\n"..delim) do
                        cosmo.yield{heading=heading, content=content}
                     end
                  end
   }
end

Save this to ~/sputnik/share/lua/5.1/sputnik/actions/s9.lua

Let's make a node "Slideshow_Demo". (Yes, this one.)

1. Put the markdown-formatted presentation in the body.
   • Use H2 (##) as slide titles
2. Set templates to _templates_for_s9
3. Set actions to slides="s9.slides"

Save.

Check that Slideshow_Demo displays fine. Then try "Slideshow_Demo.slides".

(Remember that you need "FullerScreen" - https://addons.mozilla.org/en-US/firefox/addon/4650)

Note that it's still a wiki

Wikilinks work as long as we append ".slides to them"

For example: Slideshow Demo 2

To do: no way to link to specific slides

We can also create a prototype

(Handy if we'll be making many slideshows).

1. Create a node "@Slideshow"
2. Set templates to _templates_for_s9
3. Set actions to slides="s9.slides"

Then create new slideshow nodes by just setting prototype to `@Slideshow'
