【笔记】Hexo过滤器的执行顺序

发表于 更新于 阅读次数：

前言

Hexo常用过滤器的执行顺序

测试程序

  • after_init->post_permalink->before_post_render->after_post_render->before_generate->after_generate->before_exit

before_generate和after_generate在运行过程中会随着文章内容的改变而反复执行
before_post_render、after_post_render、count_post_permalink会执行不止一次，由文章的数量决定执行的次数
本篇没有介绍到但是官方文档提及的过滤器有（因为我没看懂😂）：template_locals、new_post_path、after_render、server_middleware
