Marp is a simple (Github-flavored) Markdown editor for building PDF presentations.
The program opens with a mostly blank interface: an empty pane on the left, an empty frame on the right and a simple menu.
Type starting in the left-hand pane, though, and it begins to make more sense. Whatever you enter appears in the right-hand pane as a preview of the slide.
The text and slides are formatted by an extended version of Markdown, a simple markup language. To make text italic you surround it with *asterisks*; use two and it becomes **bold**; dashes are used to create bulleted lists (- one, - two, - three); [inline links are easy](https://www.google.com); and you get the idea.
The program doesn't make much effort to help beginners. You might automatically select some text and press Ctrl+B to style it, for instance, and that would be easy for the program to detect and convert, but-- it doesn't. There's no support for the usual text styling keyboard shortcuts at all.
Other elements are more obvious, like the drag and drop support for images, and there's an example presentation to walk you through some of the basics.
More experienced users will appreciate the ability to include equations, set an image as a background, insert footers and page numbers, apply themes and more.
When you're done, the presentation can be exported as a PDF, ready for sharing with the world.
Version 0.0.10 is a bug fix release. (Changelog)
Marp is an interesting way to create simple presentations, but you'll need to be very familiar with Markdown to get anywhere, and even then it only supports basic layouts.
