There are implementations in C and Rust. You can track their development at the following links:


The spec is not finalized and anything can change at this point.


Special characters

You can also use % to act as a comment, since it’s also a comment in LaTeX. Be careful not to start a new slide by accident though.

An Example

^ \documentclass{beamer}[12pt]
^ \title{beam}
^ \author{Dennis Chen}


# Introduction

~ What is beam?
- beam is a file format to write presentations with
- beam is a program that converts beam files into beamer

~ Why?
beam does for beamer what Markdown does for HTML
- beamer takes far too long to write.
- We only need a subset of beamer's features

# Features

~ Frametitles
Use the ``~'' character to set the frametitle.

~ Bullet points
- You've already seen it in this presentation.
- Bullet points invoke the ``itemize'' environment.

~ Block
> How to make a block
> This symbol makes a block.

~ Exampleblock
< How to make an exampleblock
< This symbol makes an exampleblock.

~ Alertblock
! How to make an alertblock
! This symbol makes an alertblock.

~ Images
Use the ``\@'' character to set a background image.


You can also use the ``\*'' characater to include an image in the slide.

# Miscellaneous

~ Stylization
beam should be written in all lowercase, even at the start of a sentence.
