之前一直使用 RTM 服务接受任务到期提醒。

terminal - todo.txt - remind - (awesome WM 提醒)

                                    (iOS/Android 提醒)
  1. 除了 todo.txt 还需要额外维护一个 remind 文件
  2. remember the milk 服务按年收费，属于长期投入

最近发现一个 todo.txt 增强版，以及一个 pushover 服务。结合两者可以实现：

terminal - todo.txt
               \
                https://pushover.net
                        \
                        (iOS/Android 提醒)

  1. todo.txt 易用性实用性美观性得到极大改善

     m:marker and m:(a marker with spaces), especially

 A:2012-04-01 ... Z:2012-01-01 prioritize on date.
 d:2012-12-12 deprioritize after date.
 a:42         "also, <a href>" related to task number. No action on do and trash.
 a:(gg foo)   explicit search URL for the browse action.
 l:42         unidirectionally linked to task number, which becomes done (but not
              trashed) recursively.
              There is no marker for bidirectional linking; if you want to mark
              one task done when another is done and vice versa, they are
              probably duplicates, and one of them should be deleted.
              Alternatively, cross-link them separately: todo.sh dup link 42 43
 k:42         kill task number, which is trashed when this task is done.
 j:42         bidirectionally joined / contradependent with task number;
              when one is done, the other(s) are trashed recursively.
 j:goal       joined to goal; when this is done, other tasks with the same goal
              are trashed.
 t:2010-10-10 future task becomes due on the date, created via todo.sh schedule
 u:2011-12-01 do-until, ultimate, latest due date until the task should have been
              done.
 w:42         waiting for task number, created via todo.sh wait ITEM# for 42
 w:Gina       waiting for person / event, created via todo.sh wait ITEM# Gina
 x:42         trash as a duplicate of task 42; useful as an alternative to
              todo.sh dup del when editing in other clients.
 x:2011-12-01 trash on date.
 z:2011-12-01 do-until-then-trash, ultimate, latest due date; after it, the task
              is trashed.

  2. pushover 服务免费，客户端安装时一次性收费(￥30)

todo.txt (增强版)并没有默认支持 pushover，找了一个简易版 todo.txt 的插件并改造了一下：
