latex初学笔记
前言
近日，苦于word实在不会用的问题，我找到了一款免费的编辑神器——latex，虽然我现在还不太会用，有许多强大的功能还不知道，但我已经被我已知的少量latex功能震惊了。
安装
步骤一.在清华镜像开源站下载iso文件
步骤二.解压该文件后选择install-tl-windows.bat运行，或者选择install-tl-advanced.bat（这个可以自定义去掉一些不要的包）运行
步骤三.当然是选一个好的编译器啦~
编译器
我用的是gvim,再下载一个Vim-Latex插件。配置vimrc是一个非常痛苦的过程，这里就略去了。
这里展示一下效果：

basicstyle=\con, % the size of the fonts that are used for the code
breakatwhitespace=false, % sets if automatic breaks should only happen at whitespace
breaklines=true, % sets automatic line breaking
captionpos=b, % sets the caption-position to bottom
commentstyle=\ttfamily\color{lightgray},

deletekeywords={}, % if you want to delete keywords from the given language
escapeinside={}, % if you want to add LaTeX within your code
extendedchars=true, % lets you use non-ASCII characters; for 8-bits encodings only, does not work with UTF-8
% frame=single, % adds a frame around the code
keepspaces=true, % keeps spaces in text, useful for keeping indentation of code (possibly needs columns=flexible)
keywordstyle=\color{red}, % keyword style
language=C++, % the language of the code
morekeywords={}, % if you want to add more keywords to the set
numbers=left, % where to put the line-numbers; possible values are (none, left, right)
numbersep=5pt, % how far the line-numbers are from the code
numberstyle=\tiny\color{gray}, % the style that is used for the line-numbers
% rulecolor=\color{white}, % if not set, the frame-color may be changed on line-breaks within not-black text (e.g. comments (green here))
showspaces=false, % show spaces everywhere adding particular underscores; it overrides 'showstringspaces'
showstringspaces=false, % underline spaces within strings only
showtabs=false, % show tabs within strings adding particular underscores
stepnumber=1, % the step between two line-numbers. If it's 1, each line will be numbered
stringstyle=\color{Orange}, % string literal style
tabsize=2, % sets default tabsize to 2 spaces
title=\lstname % show the filename of files included with \lstinputlisting; also try caption instead of title

用latex写作业
疫情期间还可以用latex写网课的作业，都不用另外去买纸和笔了
写出来是不是非常漂亮呢？
