1.正向索引

在VScode setting.json中添加如下代码，注意将路径替换为自己的SumatraPDF路径和VScode路径。

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

2.反向索引

打开SumatraPDF，点击 选项>>设置>>高级选项,将配置改为如下。

InverseSearchCmdLine = code"C:/Users/Rorschach/AppData/Local/Programs/Microsoft VS Code/Code.exe" "C:/Users/Rorschach/AppData/Local/Programs/Microsoft VS Code/resources/app/out/cli.js" --ms-enable-electron-run-as-node -gr "%f":"%l"
EnableTeXEnhancements = true

注意：如果设置了自动清除的命令，需将.synctex.gz文件注释掉，.synctex.gz文件是Latex转发到外部查看器时的辅助分件，删除将无法正常反向索引。
