如何使用VSCode编写Latex？

概要

先安装texlive,然后安装VSCode.
我这里步骤是全的，但说的不那么细。
只介绍VSCode中的配置方法。

VSCode配置步骤

1. 安装LaTex Workshop插件

2. 配置Latex编译环境

将下列配置粘入settings.json文件中。

}

3. 下载安装SumatraPDF

SumatraPDF官网链接

而后在settings.json中加入下列配置文件（注意修改第4行和第11行路径）

"latex-workshop.view.pdf.external.viewer.args": [
            "%PDF%"
        ],
    "latex-workshop.view.pdf.external.synctex.command": "C:/Users/dell/AppData/Local/SumatraPDF/SumatraPDF.exe", // 注意修改路径
    "latex-workshop.view.pdf.external.synctex.args": [
            "-forward-search",
            "%TEX%",
            "%LINE%",
            "-reuse-instance",
            "-inverse-search",
            "\"C:/Users/dell/AppData/Local/Programs/Microsoft VS Code/Code.exe\" \"C:/Users/dell/AppData/Local/Programs/Microsoft VS Code/resources/app/out/cli.js\" -r -g \"%f:%l\"", // 注意修改路径
            "%PDF%"
        ]
