What to do if vscode latex cannot be previewed

vscode latex无法预览怎么办?

在VS Code下实时预览Markdown和LATEX

相关推荐:vscode教程

这几天预习期末考试,打算找个方便的文本编辑器记笔记。刚安装了VS Code,用起来觉得挺顺手的,本身还可以实时预览Markdown,就打算直接用它了。

然而Markdown原生并不支持LATEX,打公式只能用如等html tag凑活将就,费时又费力。去VS Marketplace看了一下儿,发现有一款叫Instant Markdown的插件可以用实时把markdown源文件送到浏览器并render预览效果。虽然原生也不支持LATEX,但是可以改嘛!亲自动手丰衣足食,何乐而不为。

心乐之,果断安装。装完随手打开一个.md文件,发现这个插件已经自动用默认浏览器打开了一个网页,render出效果。自己动手改了改这个插件,加上MathJax Library,就已经可以render出Markdown中的LATEX了。步骤如下:

首先在终端/命令提示符下 cd $HOME/.vscode/extensions/dbankier.vscode-instant-markdown-0.1.0/node_modules/instant-markdown-d 进入 instant-markdown 插件的目录。

打开 index.html,在标签内添加以下代码:

 <script type="text/x-mathjax-config">
  MathJax.Hub.Config({tex2jax: {inlineMath: [[&#39;$&#39;,&#39;$&#39;], [&#39;\\(&#39;,&#39;\\)&#39;]]}});
  </script>
  <script type="text/javascript" async
    src="https://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS_CHTML">
  </script>
Copy after login

socket.on(&#39;newContent&#39;, function(newHTML) {
  document.querySelector(".markdown-body").innerHTML = newHTML;
Copy after login

后加入一行

MathJax.Hub.Queue(["Typeset",MathJax.Hub]);
Copy after login

既:

<script>
    var socket = io.connect(&#39;http://localhost:8090/&#39;);
    socket.on(&#39;connect&#39;, function () {
      socket.on(&#39;newContent&#39;, function(newHTML) {
        document.querySelector(".markdown-body").innerHTML = newHTML;
+        MathJax.Hub.Queue([&quot;Typeset&quot;,MathJax.Hub]);
      });
      socket.on(&#39;die&#39;, function(newHTML) {
        window.open(&#39;&#39;, &#39;_self&#39;, &#39;&#39;);
        window.close();
        var firefoxWarning =
        "<h1>Oops!</h1>" +
        "<h3>Firefox doesn&#39;t allow windows to self-close.</h3>" +
        "<h3>If you want the preview window to close automatically like in other browsers, go to about:config and set dom.allow_scripts_to_close_windows to true.</h3>"
        document.body.innerHTML = firefoxWarning;
      });
    });
  </script>
Copy after login

4 . 保存,关闭网页,重启VS Code,万事大吉。
