 1 | # OrangeX4's HyperSnips
 2 | 
 3 | You can use it in vscode instead of vim like
 4 | https://castel.dev/post/lecture-notes-1/#fractions
 5 | 
 6 | Use it via vscode extension https://marketplace.visualstudio.com/items?itemName=OrangeX4.hsnips
 7 | 
 8 | Specially, it support **math environment**! It only goes into effect in `$...$`, `$$...$$`, etc...
 9 | 
10 | For example:
11 | 
12 | ```
13 | (1+2)/    --->    \frac{1+2}{}
14 | ```
15 | 
16 | The snippets is adapted from https://zhuanlan.zhihu.com/p/199268436.
17 | 
18 | 需要和 [HyperSnips for Math](https://marketplace.visualstudio.com/items?itemName=OrangeX4.hsnips) 插件配套使用.
19 | 
20 | **安装完成后**, 按下快捷键 `Ctrl + Shift + P`, 输入命令 `Open Snippets Directory`, 就可以打开一个文件夹. 在 **该文件夹** 新建一个文件 `markdown.hsnips`, 并将 [OrangeX4's hsnips](https://github.com/OrangeX4/OrangeX4-HyperSnips/blob/main/markdown.hsnips) 里面的内容输入进去, 保存, 就可以使用了.
