关于Markdown的一些学习笔记

**关于Markdown的一些学习笔记**
一直利用markdown进行博客的文档编写，一方面是因为不需要特别注重排版，另一方面是十分的方便。最近突发奇想的认为，如果能运用到平时的作业或课程中，会不会也是极大的提高效率的一大方式呢?
## Markdown装成pdf格式
在网上查了相关的资料，总结起来有：
1.Markdown编辑器自带的转换pdf功能
此功能比较方便，且能确保格式正确；但是目前这个功能一般都是付费使用的。
2.转换成html格式后，再利用浏览器的另存为pdf生成pdf，但这种方法生成的pdf和所使用的浏览器自带格式相关，可能存在一些错误，所以需要注意一下。
3.利用pandoc
pandoc一直被评为“瑞士军刀”，因为在很多格式面前都有很大的作用；但是此方法更适合应用在linux系统上，此外在针对中文编码上需要先安装latex才可以。
4.在线转换pdf
这里介绍一个比较好的转换网址，可将md文件格式转换成pdf的[网站](http://www.mdtr2pdf.com/index_en.html)，转换效果笔者认为还算不错的。

Markdown制作ppt

平时制作PPT都是找到一个PPT模板，然后进行修改；往往找一个模板要考虑他的背景和动画效果；但如果时间很紧的话，这样显得不是特别的解决之道。如果熟悉Markdown的话，可以利用Marp这个编辑器，选择自己喜欢的ppt背景并生成pdf；在制作ppt上感觉速度还是较快的。Marp源代码在这里；而具体的release版本在这里。

这里放出marp的一个模板

Directives

Marp's Markdown has extended directives to affect slides.

Insert HTML comment as below:

<!-- {directive_name}: {value} -->

<!--
{first_directive_name}:  {value}
{second_directive_name}: {value}
...
-->

---

Global Directives

$theme

Changes the theme of all the slides in the deck. You can also change from View -> Theme menu.

<!-- $theme: gaia -->

Theme name	Value	Directive
Default	default	<!-- $theme: default -->
Gaia	gaia	<!-- $theme: gaia -->

---

$width / $height

Changes width and height of all the slides.

You can use units: px (default), cm, mm, in, pt, and pc.

<!-- $width: 12in -->

$size

Changes slide size by presets.

Presets: 4:3, 16:9, A0-A8, B0-B8 and suffix of -portrait.

<!-- $size: 16:9 -->

---

Page Directives

The page directive would apply to the current page and the following pages.

You should insert it at the top to apply it to all slides.

page_number

Set true to show page number on slides. See lower right!

<!-- page_number: true -->

---

template

Set to use template of theme.

The template directive just enables that using theme supports templates.

<!--
$theme: gaia
template: invert
-->

Example: Set "invert" template of Gaia theme.

---

footer

Add a footer to the current slide and all of the following slides

<!-- footer: This is a footer -->

Example: Adds "This is a footer" in the bottom of each slide

---

prerender

Pre-renders a slide, which can prevent issues with very large background images.

<!-- prerender: true -->

---

Pro Tips

Apply page directive to current slide only

Page directive can be selectively applied to the current slide by prefixing the page directive with *.

<!-- *page_number: false -->
<!-- *template: invert -->

---

Slide background Images

You can set an image as a slide background.

![bg](mybackground.png)

Options can be provided after bg, for example ![bg original](path).

Options include:

• original to include the image without any effects
• x% to include the image at x percent of the slide size

Include multiple![bg](path) tags to stack background images horizontally.

Maths Typesetting

Mathematics is typeset using the KaTeX package. Use $ for inline maths, such as \(ax^2+bc+c\), and $$ for block maths:

\[I_{xx}=\int\int_Ry^2f(x,y)\cdot{}dydx
\]

This is inline: $ax^2+bx+c$, and this is block:

$$I_{xx}=\int\int_Ry^2f(x,y)\cdot{}dydx$$
