晚上睡觉前我会固定地做下面一系列的事情：检查每日待办，写总结，记录习惯。这些事情都是在emacs中进行，存放在不同的文件中。我发现每次当我做其中一件时，都要反应一下需要打开什么文件，这就很烦。本着不让大脑在重复的事情上增加思考的原则，想到了实现“将一系列固定工作流自动化执行”的想法，这便有了autoflow.el。

使用

使用 define-autoflow 宏定义一个自动流程。该宏的第一个参数是流程的名字，剩下的参数需要提供一系列的函数。M-x autoflow-start 命令选择事先定义好的一个流程后开始执行，每做完一件事情，继续 M-x autoflow-start，直到整个工作流结束。

比如下面定义了一个我每晚睡前总结的工作流:

(define-autoflow "summary routine"
  (para-daily-page-today) ;; 1.检查今日计划
  (para-find-habit) ;; 2.记录习惯完成情况
  (para-find-summary)) ;; 3.写今日总结
