Slide Show Plugin

This plugin converts a topic with headings into a slideshow.

Introduction

There is already a defacto standard for presentations, why this plugin? This plugin makes sense for organizations that do already have lots of content in TWiki: 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 the other presentation program, but the markup of TWiki and other plugins like TWiki:Plugins/ChartPlugin, TWiki:Plugins/GaugePlugin, TWiki:Plugins/SpreadSheetPlugin, TWiki:Plugins/TWikiDrawPlugin 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 is shown in the usual TWiki rendering, representing the outline of the slideshow. This mode is useful to print 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 like paragraphs, bullets, tables and images.
    • Hint: Make sure to keep each slide short enough so that you do not need to scroll to see all text of a slide during the presentation.
    • Note: You can use any heading level you like, but use the same 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 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
    %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:
