VS Code+Sumatra PDF正反向搜索

简介

重新装机后，在配置VS Code和LaTeX的环境后，问题卡在了正反向搜索这边，简单记录下。

综合参考以下链接：

• VS Code + Tex Live + SumatraPDF配置LaTeX反向搜索（持续更新）
• 解决SumatraPDF 在VS Code上反向搜索失效
• Sumatra PDF反向搜索的问题记录 (texlive+vscode)

正向

在安装LaTeX Workshop后，打开VS Code的settings.json

左边是只读，右边是编辑，在右边写入设置就可以了

首先是配置基本的命令参数，常用的就是这三种

"latex-workshop.latex.tools": [
    {
        "name": "xelatex",
        "command": "xelatex",
        "args": [
            "-synctex=1",
            "-interaction=nonstopmode",
            "-file-line-error",
            "-pdf",
            "%DOCFILE%"
        ]
    },
    {
        "name": "pdflatex",
        "command": "pdflatex",
        "args": [
            "-synctex=1",
            "-interaction=nonstopmode",
            "-file-line-error",
            "%DOCFILE%"
        ]
    },
    {
        "name": "bibtex",
        "command": "bibtex",
        "args": [
            "%DOCFILE%"
        ]
    }
],

然后是由上述基本命令引出的编译链

"latex-workshop.latex.recipes": [
    {
        "name": "xelatex",
        "tools": [
            "xelatex"
        ]
    },
    {
        "name": "pdflatex",
        "tools": [
            "pdflatex"
        ]
    },
    {
        "name": "xe->bib->xe->xe",
        "tools": [
            "xelatex",
            "bibtex",
            "xelatex",
            "xelatex"
        ]
    },
    {
        "name": "pdf->bib->pdf->pdf",
        "tools": [
            "pdflatex",
            "bibtex",
            "pdflatex",
            "pdflatex"
        ]
    }
],

接着配置外部PDF阅读器

"latex-workshop.view.pdf.viewer": "external",
"latex-workshop.view.pdf.ref.viewer": "external",
"latex-workshop.view.pdf.external.viewer.command": "C:/Users/AppData/Local/SumatraPDF/SumatraPDF.exe",

接下来才是正向搜索：

1. 首先保证.gz不会被删除

2. 同样地，在settings.json写入配置

   "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",
       "%PDF%"
   ],

有人在latex-workshop.view.pdf.external.synctex.args加入反向搜索的命令，但其实不会起作用，反向搜索只要在Sumatra PDF中设置就可以了

1. 设置正向搜索等快捷键，打开keybindings.json

   {
          "key": "alt+s",
          "command": "latex-workshop.synctex",
          "when": "editorTextFocus && !isMac"
      },
      {
          "key": "alt+b",
          "command": "latex-workshop.build",
          "when": "editorTextFocus && !isMac"
      },
      {
          "key": "alt+t",
          "command": "latex-workshop.kill",
          "when": "editorTextFocus && !isMac"
      },
      {
          "key": "alt+e",
          "command": "latex-workshop.recipes"
      },

这样就可以通过alt+s来正向搜索

反向

在Sumatra PDF的设置->选项中，设置反向搜索命令：

"C:\Users\AppData\Local\Programs\Microsoft VS Code\Code.exe" "C:\Users\AppData\Local\Programs\Microsoft VS Code\resources\app\out\cli.js" --ms-enable-electron-run-as-node -r -g "%f":"%l"

• 第一个参数是VS Code的所在位置
• 第二个参数的cli.js和第三个参数的--ms-enable-electron-run-as-node是避免VS Code使用子进程打开Sumatra PDF后，Sumatra PDF无法反向搜索的情况
