你在准备一场演讲的时候，脑海可能会先被图文并茂、形象华丽的演示图稿所占据。诚然，没有人会否认一份生动形象的演讲稿所带来的积极作用。然而，并非所有的演讲都需要TED Talk的质量。更多时候，演讲稿只为传达特定的信息。 而这个，使用文本信息足以完成。在这种情况下，你的时间可以更好的花在信息的搜集和核实上面，而不是在谷歌图片搜索（Google Image）上寻找好看的图片。

在Linux的世界里，有几个不同的方式供你选择来做演讲。比如带有大量多媒体展示、视觉冲击效果极佳的[Impress.js][1]，专为LaTex用户提供的Beamer，等等。而如果你苦于寻找一种简单的方式来创建并且展示文本演示稿，[mdp][2] 就能帮你实现。

### 什么是Mdp？ ###

mdp是Linux下一款基于ncurses的命令行演示工具。我喜欢mdp在于它对[markdown][3]的支持，使得我很容易以熟悉的markdown格式来创建幻灯片。自然，它还可以很轻松地用HTML格式来发布幻灯片。另一个好处是它支持UTF-8字符编码，这让非英语字符（如希腊或西里尔字母）的展示也变得很方便。

mdp的依赖需求很少（如 ncursesw），这使得安装非常简单。

安装mdp完毕，你可以使用你喜欢的文本编辑器来轻松创建一个演示稿。如果你熟悉markdown的话，很快就可以驾驭mdp。而对于那些不熟悉markdown的人来说，学习mdp最好的方式就是从一个实例着手。

### 在命令行中展示演示稿 ###
|
|
|
|
|
|
|
|
|
|
|
|
当你把以上代码保存为slide.md的文本文件后，你可以运行以下命令来展示演示稿：
|
|
|
|
|
|
|
|
|
|
|
|
$ mdp slide.md
|
|
|
|
|
|
|
2015-02-09 21:58:12 +08:00
|
|
|
|
你可以通过按键 回车/空格/下翻页/向下光标键 (下一张幻灯)、回退/上翻页/向上光标键 (上一张幻灯)、Home (幻灯首页)、 End (幻灯末页)或者 数字N (第N页幻灯)来操作你的演示稿。
|
2015-02-09 20:58:29 +08:00
|
|
|
|
|
|
|
|
|
|
演示稿的标题将在每页幻灯的顶部展示，而你的名字和页码则会出现在幻灯的底部。
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
这是嵌套列表和多层次标题的实例效果。
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
这是代码片段和内联代码的实例效果。
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
这是嵌套引用的实例效果。

### 总结 ###
|
|
|
|
|
|
|
|
|
|
|
|
在本教程中，我演示了在命令行中如何使用mdp来创建并且展示一个演示稿。mdp的markdown兼容性让我们省去了学习其它新格式的麻烦，这相对于另一种名为[tpp][5]的演示工具来说是一个优势。拘于mdp的局限性，它可能无法作为你的默认演示工具。但是，值得肯定的是它一定能在某个场合下派上用场。你觉得mdp怎么样呢？你还喜欢其它的什么东西吗？
