自动生成文章永久链接

Ghlerrix2022/07/22blogblog

因为两个主题在文章目录的管理有些许区别,自动生成文章永久链接分为两个版本，一个对应Vdoing主题，一个对应reco。

自动生成文章永久链接，不仅仅会自动生成permalink，还会同时根据所在子目录自动生成categories和tags。其实Vdoing主题本身是有自动生成frontMatter功能的，但是需要在dev或者build的时候生效，但是我们所有的编译交予gihub的自动工作流程，因此我写了这个脚本在执行deploy的时候生成frontMatter.

Vdoing版本

该版本会同时生成author信息，需在代码开头自己设定
