LaTeX learning

Happy LaTeXing!

LateX 本地配置参考文章：

Windows: sublime + sumatraPDF：

Shortkey	Function
`Ctrl`+`L`, then `J`	forward search
double click	reverse search
`Ctrl`+`L`, then `Backspace`	clear tmp files
`Ctrl`+`K`, then `Ctrl`+`B`	open/close sidebar

Windows: VSCode + sumtraPDF

Shortkey	Function
`Ctrl`+`Alt`+`J`	forward search
double click	reverse search
`Ctrl`+`Alt`+`C`	clear tmp files
`Ctrl`+`Alt`+`V`	open and view the pdf

Bug

If I open VSCode and SumatraPDF (doesn't from VSCode), the inverse search works perfectly. But if I open SumatraPDF from VSCode (use Ctrl+Alt+V), the inverse search can't work. So tricky! The Solution is as followed.

You can not just change the option setting through SumatraPDF application GUI. You must modify the SumatraPDF-settings.txt file in the installation directory following the guide in LaTeX-Workshop wiki.

SumatraPDF inverse search did not work well for VSCode.exe/VSCodium.exe

Roadmap¶

Learning $\LaTeX$ begins from reading Overleaf's comprehensive documents.

YouTuber creation： LaTeX Cheat Sheet

The TeXbook -- Donald E. Knuth. Some people have said that it's a little hard to get through this book, but when I tried reading it, I found it much eaiser to appreciate than any other documents or books I've read. Because he tell the low-level mechanisms in simple terms which makes me feel comfortable.

Tricks¶

In terminal, like

texdoc symbols command pops up The Comprehensive $\LaTeX$ Symbol List document.

texdoc latexcheat command pops up a two-pages cheatsheet.

LaTeX syntax tips¶

math code

inline mathdisplay math

内置功能：$ ... $, $ ... $ , \begin{math} ... \end{math}

内置功能： \[ ... \], $$ ... $$, \begin{displaymath} ... \end{displaymath}

amsmath package提供：

\begin{equation*} ... \end{equation*}, \begin{equation} ... \end{equation}(编号)
\begin{align*} ... \end{align*}, \begin{align} ... \end{align}(编号)

✨ equation仅支持单行公式；align支持多行公式，可以通过&指定对齐位置，但是每行都有编号。

✨ pairs of dollar sign is no longer recommended: Why use \[...\] in place of $$...$$?

实现多行公式，但只有一个编号：

\begin{equation}
  \begin{aligned}
    a &= b + c \\
    &= d + e + f \\
  \end{aligned}
\end{equation}

fonts¶

typeface = family	manual setup command	application	remark
serif (roman)	`\setmainfont`	正文字体	mostly in the `article`
sans serif	`\setsansfont`	标题/强调, like `\section`,`\title`	by default `beamer` uses the sans serif font throughout the document.
typewriter (monospace)	`\setmonofont`	代码	/

Mathmatical symbols fonts¶

\mathcal: calligraphic. 通常用来表示集合、函数空间等. $\LaTeX{}$默认支持，无需external package.

\[ \mathcal{A}, \mathcal{B}, \mathcal{C}, \mathcal{D}, \mathcal{E}, \mathcal{F}, \mathcal{G}, \mathcal{H}, \mathcal{I}, \mathcal{J}, \mathcal{K}, \mathcal{L}, \mathcal{M}, \mathcal{N}, \mathcal{O}, \mathcal{P}, \mathcal{Q}, \mathcal{R}, \mathcal{S}, \mathcal{T}, \mathcal{U}, \mathcal{V}, \mathcal{W}, \mathcal{X}, \mathcal{Y}, \mathcal{Z} \]

\mathcal{A}, \mathcal{B}, \mathcal{C}...

\mathbb: blackboard bold. 通常用于表示常见的数学集合，例如实数集$\mathbb{R}$、整数集$\mathbb{Z}$、自然数集$\mathbb{N}$等. 在preamble中需要加载 amsfonts 或 amssymb 包来支持.

\[ \mathbb{A}, \mathbb{B}, \mathbb{C}, \mathbb{D}, \mathbb{E}, \mathbb{F}, \mathbb{G}, \mathbb{H}, \mathbb{I}, \mathbb{J}, \mathbb{K}, \mathbb{L}, \mathbb{M}, \mathbb{N}, \mathbb{O}, \mathbb{P}, \mathbb{Q}, \mathbb{R}, \mathbb{S}, \mathbb{T}, \mathbb{U}, \mathbb{V}, \mathbb{W}, \mathbb{X}, \mathbb{Y}, \mathbb{Z} \]

\mathbb{A}, \mathbb{B}, \mathbb{C}...

Package management¶

preamble

\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{graphicx}
\graphicspath{{figures/}}
\usepackage{float}
\usepackage{geometry}
\geometry{margin=1in}
\usepackage{hyperref}

Edit Tips¶

LaTeX中常见的空格命令

命令	名称	宽度（近似）	典型用途
`\,`	小空格 thin space	1/6 em¹	单位符号，公式中的轻微间距
`␣`	普通空格	1 em	文本中的常规空格（可能被忽略）
`\␣`	强制空格	1 em	确保不被忽略的空格
`\:`	中空格 medium space	2/9 em	数学模式中的中等间隔
`\;`	大空格 thick space	5/18 em	数学模式中的较大间隔
`~`	不可换行空格	1 em	保证词组不分开（如"Fig.~1"）
`\quad`	1 em 空格	1 em	较大的固定间隔（如分割文本）
`\qquad`	2 em 空格	2 em	更大的固定间隔
`\hspace{长度}`	自定义空格	任意指定	精确控制间距（如`\hspace{5pt}`）

Caution¶

The $\LaTeX$ engine converts multiple consecutive line breaks into \par. An Empty line is used for writing convenience, but the effect is equivalent.

An em (from em quadrat) is a unit in the field of typography, equal to the currently specified point size. It corresponds to the body height of the typeface. For example, one em in a 16-point typeface is 16 points. Therefore, this unit is the same for all typefaces at a given point size. ↩
