Regular Expressions，缩写为 Regex 或 Regexp

regex-matter

https://github.com/bubkoo/hexo-filter-fenced-code/issues/3

var rFenceCode = /(\s*)(`{3,}|~{3,}) *(.*) *\n?([\s\S]+?)\s*(\2)(\n+|$)/g;

regex	解释
(\s*)(`{3,} \| ~{3,})	``` 或者 ~~~
`(.)`	至少 1 个空格+至少 1 个任意字符
`*\n?`	至少 1 个空格+可有可无换行错误原因就是此,我习惯 trim 行尾的空格,所以无法正常匹配

regex-多对多替换

我在切换图床时想实现如下 多对多替换 的需求

vscode-批量替换

一

Screenshot_20210313_171408_tv.danmaku.bili
-> Screenshot20210313171408

Screenshot_\d+_\d+_tv.danmaku.bili`
-> Screenshot\d+\d+

二

匹配下面内容

categories:
  - experience
  - shell
tags:
  - experience
  - shell

categories:*tags:
行不通, 其中间含有 \n
categories:\n((.)±(.)+\n)+tags:\n((.)±(.)+\n)+

尽短匹配

比如上面一大段, 想要匹配出来每段 D:\Scoop...;, 用 D:\\Scoop.+; 的匹配结果为一大段:
