今天看到这个，TermNote。

ruby 来写和演示类似 ppt 的文档。

require 'termnote'

include TermNote

show.add chapter title: "Hello, World"
show.add code language: "Ruby", source: <<-SOURCE
  puts "Hello, world!"
SOURCE
show.start

Or via a .yaml file:

---
type: chapter
title: Hello, World
subtitle: By Kurtis
---
type: code
source: |
  puts "Hello, world!"
