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b96cac025db4031319c29e1eb68f19d6和2cdea26b4c3988e37d674b56660962a7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 $HOME/.vscode/extensions/dbankier.vscode-instant-markdown-0.1.0/node_modules/instant-markdown-d 进入 instant-markdown 插件的目录。
打开 index.html,在93f0f5c25f18dab9d176bd4f6de5d30e标签内添加以下代码:
<script type="text/x-mathjax-config"> MathJax.Hub.Config({tex2jax: {inlineMath: [['$','$'], ['\\(','\\)']]}}); </script> <script type="text/javascript" async src="https://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS_CHTML"> </script>
在
socket.on('newContent', function(newHTML) { document.querySelector(".markdown-body").innerHTML = newHTML;
后加入一行
MathJax.Hub.Queue(["Typeset",MathJax.Hub]);
既:
<script> var socket = io.connect('http://localhost:8090/'); socket.on('connect', function () { socket.on('newContent', function(newHTML) { document.querySelector(".markdown-body").innerHTML = newHTML; + MathJax.Hub.Queue(["Typeset",MathJax.Hub]); }); socket.on('die', function(newHTML) { window.open('', '_self', ''); window.close(); var firefoxWarning = "<h1>Oops!</h1>" + "<h3>Firefox doesn'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>
4 . 保存,关闭网页,重启VS Code,万事大吉。
