浅谈VSCode配置LaTeX编辑器的方法

将以下代码放入设置区：

"latex-workshop.latex.tools": [
    {
        // 编译工具和命令
        "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%"
        ]
    }
],

LaTeX Workshop 默认的编译工具是 latexmk，大家根据需要修改所需的工具和命令，我不需要用到 latexmk，因此我把其修改为中文环境常用的 xelatex，大家根据需要自行修改。（感谢 @huan Yu ，将 tools 中的 %DOC%替换成%DOCFILE%就可以支持编译中文路径下的文件了）

"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"
        ]
    }],

要使用 pdflatex，只需在 tex 文档首加入以下代码：

%!TEX program = pdflatex

要使用 SumatraPDF 预览编译好的PDF文件，添加以下代码进入设置区。

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

图标，再点击你所想要使用的 Recipe 就可以编译了，如果用快捷键则默认使用第一条 Recipe 编译。单击右上角的放大镜按钮或按 Ctrl+Alt+v 打开 SumatraPDF 进行预览。

4. 配置正向和反向搜索

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

在PDF中双击即可反向搜索

不要清理生成的名字中带 synctex 的文件，否则就不能进行正向和反向搜索；

之前的文章中，我提到了从 VSCode 预览按钮启动 SumatraPDF 会无法反向搜索的问题，现在已经解决，解决方法是在反向搜索命令中添加

"resources\app\out\cli.js"

解决方案来源：

https://github.com/James-Yu/LaTeX-Workshop/issues/637#issuecomment-473145503

这个方法目前有个 bug，SumatraPDF 要从 VSCode 中打开才能进行反向搜索，单独打开的 SumatraPDF 在进行反向搜索时会跳转到 VSCode 的配置文件 cli.js。

6. 快捷键设置

在 VSCode 界面下按下 F1，键入“keyjson”，选择“打开键盘快捷方式(JSON)”，然后把以下代码放入：

{
    "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"},

这段代码的意义是将 Alt+s 绑定到正向搜索，将 Alt+b 绑定到使用默认 recipe 编译，将 Alt+t 绑定到终止编译，将 Alt+e 绑定到选择其他 recipe 编译，可以自行更换为适合自己的快捷键，只需修改“key”那一项即可。

7. 其他设置

• LaTeX Workshop 默认保存的时候自动编译，如果不喜欢这个设置，可以添加以下代码进入设置区：

"latex-workshop.latex.autoBuild.run": "never",

• 如果编译出错，插件会弹出两个很烦人的气泡，不喜欢的话可以在设置中添加以下代码：

"latex-workshop.message.error.show": false,"latex-workshop.message.warning.show": false,

注意：只需把以下代码放入设置区的方括号里，不要删去方括号，不要忘记替换软件的路径。
