2020年6月2日 更新：
Markdown Preview Enhanced 这个插件非常垃圾，BUG 满天飞，所以我建议改用 Instant Markdown。
定位文件："C:\Users\pluveto\.vscode\extensions\dbankier.vscode-instant-markdown-1.4.4\index.html"
如下增加：
<script src="//cdn.bootcss.com/mathjax/2.7.0/MathJax.js?config=TeX-AMS-MML_HTMLorMML"></script>
<script type="text/x-mathjax-config">
MathJax.Hub.Config({
showProcessingMessages: false,
messageStyle: "none",
extensions: ["tex2jax.js","TeX/mediawiki-texvc.js","TeX/noUndefined.js", "TeX/autoload-all.js", "TeX/AMSmath.js", "TeX/AMSsymbols.js"],
jax: ["input/TeX", "output/output/HTML-CSS"],
tex2jax: {
inlineMath: [ ['$','$'], ["\(","\)"] ],
displayMath: [ ['$$','$$'], ["\[","\]"] ],
skipTags: ['script', 'noscript', 'style', 'textarea', 'code'],
ignoreClass:"comment-content"
},
"HTML-CSS": {
availableFonts: ["STIX","TeX"],
showMathMenu: false
}
});
MathJax.Hub.Queue(["Typeset",MathJax.Hub]);
</script>本以为装个插件就完事了，没想到这都有坑，只好写这一篇水文记录一下。
首先安装插件：
- Markdown Preview Enhanced
- 用于 Markdown预览
- Math Snippets
- 用于快速输入表达式
- tencent-cloud-cos-upload-image
- 用来上传图片到腾讯云
然后你会发现 Markdown 不支持 Snippets，也就是没有任何代码提示。解决方法：
按 F1，打开用户设置（Open User Settings），找到一个编辑 settings.json 的入口，向配置文件追加：
"[markdown]": {
"editor.quickSuggestions": true
},追加在第一级花括号下面：
之后要把数学渲染引擎改为 Mathjax。还是在用户设置，不废话了。
以及：
"editor.suggest.snippetsPreventQuickSuggestions": true然而这样之后，Mathjax 并不会渲染。查看 html 可以发现控制台报错。我自己摸索出了解决方法：
编辑 C:\Users\USERNAME\.mume\mathjax_config.js 改为
module.exports = {
showProcessingMessages: false,
messageStyle: "none",
extensions: ["tex2jax.js", "TeX/mediawiki-texvc.js", "TeX/noUndefined.js", "TeX/autoload-all.js", "TeX/AMSmath.js", "TeX/AMSsymbols.js"],
jax: ["input/TeX", ".../../output/HTML-CSS"],
tex2jax: {
inlineMath: [['$', '$'], ["\(", "\)"]],
displayMath: [['$$', '$$'], ["\[", "\]"]],
skipTags: ['script', 'noscript', 'style', 'textarea', 'code'],
ignoreClass: "comment-content"
},
"HTML-CSS": {
availableFonts: ["STIX", "TeX"],
showMathMenu: false
}
}我提交了 issue，不知道能不能解决。
COS 配置，下面供参考：
{
// 地区，在COS对象存储中bucket对应的地域
"tencentCOSUpload.region": "",
// secretId，在 https://console.cloud.tencent.com/cam/capi 中获取
"tencentCOSUpload.secretId": "",
// secretKey，在 https://console.cloud.tencent.com/cam/capi 中获取
"tencentCOSUpload.secretKey": "",
// 输入你的bucket名称，如 a-1250000000
"tencentCOSUpload.bucket": "",
// remotePath，您的存储目录，例如要把文件存在 http://${你的域名}/images/png 这个目录下，则这里填写images/png。默认为空，即存储在根路径下
"tencentCOSUpload.remotePath": "",
// 存储桶是否为公有可访问，如为私有，且希望上传后的url带签名，则设置为false，默认是 true
"tencentCOSUpload.isPublic": "true",
// 签名有效期，单位为妙，isPublic设置为 false 时有效
"tencentCOSUpload.duration": "31536000",
// 自定义域名，原来替换引用的默认COS域名，无特殊需求可不用修改
"tencentCOSUpload.domain": "",
// 临时目录，默认 /tmp/.tencentCOSUpload，无特殊需求可不用修改
"tencentCOSUpload.localPath": "/tmp/.tencentCOSUpload"
}功能速查
图片上传
- 使用 ctrl+ alt + p (Windows) / cmd + opt + p (Mac), 粘贴板里面的图片会直接上传至cos
- 使用 ctrl+ alt + o (Windows) / cmd + opt + o (Mac), 选择本地文件上传至cos
