PresentAPL -1-

PresentAPL is a Dyalog class.
It takes a Markdown file as input
It uses MarkAPL to parse the Markdown.
It creates a slide show from the Markdown.
It uses HTML5, CSS and a bit of JavaScript to achieve that.
All it needs is a modern browser.

PresentAPL -2-

Creates a slide show (or presentation) from a Markdown file.
Uses the MarkAPL class (parser) for the conversion.
See the Markdown file this presentation was created from as a template.
There is a file Example.md available discussing all formatting options.
There is an EXE available and a class script.
In order to use the EXE you don't even need Dyalog APL.

One can use all the stuff supported by MarkAPL: paragraphs, lists, code blocks, tables, images, blockquotes, horizontal rulers, in-line markup (bold, italic, APL code, ~~deleted~~…) and more.

This is a paragraph with in-line mark-up that shows in print view only. The blank lines above and underneath this paragraph are essential. Only then are the two <div>s recognized as two rather than one HTML block, and only then is anything between the two <div>s interpreted as Markdown.

Advantages

Single stand-alone HTML file.
It's just HTML5, CSS and a bit of JavaScript.
Open Source.
Simple and easy to use.
Allows testing code expressions used in a presentation.

Disadvantages

No animations other than animated GIFs.

Workflow

Create a presentation by editing a Markdown file. AboutPresentAPL.md is an excellent starting point
Drag the *.md file onto PresentAPL.exe
View the resulting HTML file - your presentation.

Keyboard shortcuts

The following keys are used to control a PresentAPL presentation:

Key	Comment
<PgDn>	Show the next slide
<PgUp>	Show previous slide
<Home>	First slide
<End>	Last slide
Cursor-right	Show next item
Cursor-left	Hide current item
M	Toggle mouse navigation (default=off)
S	Toggle status bar visibility
P	For “Print”: shows all slides at once including any `<div>`s of the class “handout”.

Incremental

All elements are always incremental.
That means that by pressing <CursorRight> just one element at a time is revealed.
If you don't want this just press <PgDn> - this shows a whole slide at once.

Misc

I like to know when the last topic on a slide has been revealed.

The bottom-left corner shows an arrow as long as not all items are revealed.
