Slide Show Plugin

%SHORTDESCRIPTION%

Introduction

There is already a de facto standard for presentations, so why this plugin? This plugin makes sense for organizations that already have lots of content in Foswiki: It is easy to create a web based presentation that contains many links to related content. The plugin does not try to compete with the bells and whistles of other presentation programs. However, the markup of Foswiki and other plugins such as Foswiki:Extensions/ChartPlugin, Foswiki:Extensions/GaugePlugin, Foswiki:Extensions/SpreadSheetPlugin, Foswiki:Extensions/JHotDrawPlugin can be used to create appealing presentations.

Any topic with headings can be converted into a slideshow. Each slide starts with a "---++" heading. There are two modes to view a topic:

• Normal topic view mode: Headings and text are shown in the usual Foswiki rendering, representing the outline of the slideshow. This mode is useful for printing handouts.

• Presentation mode: Each heading with text is shown as a slide; the format is based on a slide template. Navigation buttons are added to go to the "First", "Previous", and "Next" slide. Slide navigation is quick because it is done with anchor jumps to the same page.

You can start the presentation by clicking on the "Start presentation" button.

Syntax rules

How to create a slideshow

• Start with %SLIDESHOWSTART%
  • Use the optional template parameter to specify your own slide template topic, e.g. %SLIDESHOWSTART{ template="MyOwnSlideTemplate" }%
• Create the slides. Start each slide with a "---++" heading and add text such as paragraphs, bullets, tables and images.
  • Hint: Make sure to keep each slide short enough that you do not need to scroll to see all text of a slide during the presentation.
  • Note: You can use any heading levels you like, but use the same levels for all slides.
• End your slideshow with %SLIDESHOWEND%

How to create your own slide template

To create your own template topic, copy the "Default Slide Template" section below into your own slide template topic and customize it to your needs. It can be activated as the default template in the plugin's TEMPLATE setting, or per slideshow with the %SLIDESHOWSTART{ template="MyOwnSlideTemplate" }% setting.

• Use a DIV or an HTML table that defines a slide. For example, create one row for the slide title, another one for the slide text.
• These keywords can be used:

  Keyword	What it means
  %SLIDETITLE%	The heading of the slide
  %SLIDETEXT%	The text of the slide
  %SLIDECOMMENT%	The comment of the slide (optional; appended to slide of missing)
  %SLIDENUM%	The current slide number
  %SLIDEMAX%	The last slide number

  * And for navigation buttons:

  %SLIDENAV%	The navigation buttons for "First", "Previous", "Next" slide
  %SLIDENAVALL%	The navigation buttons for "First", "Previous", "Next", "Last" slide
  %SLIDENAVFIRST%	The navigation button for "First slide"
  %SLIDENAVPREV%	The navigation button for "Previous slide"
  %SLIDENAVNEXT%	The navigation button for "Next slide"
  %SLIDENAVLAST%	The navigation button for "Last slide"

• Only text between %STARTINCLUDE% and %STOPINCLUDE% is used for the template.

Example

This is a short example of a slideshow. You should see a "Start presentation" button if this plugin is installed:
