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

2
3
4
5
6
7
8
9
10
11
12
13
14
15

19
20
21
22
23
24
25
26
27
28
29
30

"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

2
3

"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

   1 2 3 4 5 6 7 8 9

   "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

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

   {"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：

1

"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
