sh-todo: A minimal todo-list manager written in POSIX shell

sh-todo is my take on the minimal, command-line task manager. It allows you to add, view and complete tasks. It also supports marking tasks with a label/tag/project/context (whatever you want to call it) and filtering the effect of the supported commands to apply to only tasks with that label.
Completed tasks are marked with a completion date and appended to a log of completed tasks kept in a separate file. They remain visible in your todo list until you choose to clear them.

To install just put the todo, todone and todone-archive scripts to somewhere in your $PATH and copy sh-todo to ~/.sh-todo, editing it to your tastes. sh-todo has no external dependencies beyond a POSIX-compliant shell.

Quick start/usage

For the following examples, you'll have to use your imagination and view --text-- as strike-through. Output uses the ANSI escape sequence for strike-through by default, which will be rendered by your terminal if it supports it.

Add a task (note, no need to enclose it in quotes):

$ todo update gogdl to take account changes to gog login @hacking @evening
$ todo make appointment with doctor for next Monday @chore

View task list:

$ todo
• update gogdl to take account changes to gog login [@hacking @evening]
• make appointment with doctor for next Monday [@chore]

Complete a task (just give a substring that will match, optionally limit match to given @labels):

$ todone make appointment
• --make appointment with doctor for next Monday [@chore] (2012-07-25 16:53)--

View task list again:

$ todo
• update gogdl to take account changes to gog login [@hacking @evening]
• --make appointment with doctor for next Monday [@chore] (2012-07-25 16:53)--

Take a look at the file containing the todo list (editing with a text editor is encouraged):

$ cat path/to/my/todolist
TODO update gogdl to take account changes to gog login [@hacking @evening]
DONE make appointment with doctor for next Monday [@chore] (2012-07-25 16:53)

View tasks with a given label:

$ todo @hacking
• update gogdl to take account changes to gog login [@hacking @evening]

Remove completed todo items from main todo list:

$ todone-archive
• --make appointment with doctor for next Monday [@chore] (2012-07-25 16:53)--

Configuration

Look in sh-todo - it should be self-explanatory. You just need to set up $TODO_F and $TODONE_F which are where your current todo list and list of previously completed tasks are kept. Storing these files in a Dropbox or Ubuntu One folder is useful for syncing between multiple machines.

Questions/problems

How can I re-order tasks/delete without completing/edit existing tasks etc etc?

Just open your todo list in your favourite text editor. If you're a vim user, you'll likely find it helpful to set bindings such as these to assist in re-ordering.

How can I review recently completed tasks?

The todone file format is readable enough that tac /path/to/my/todone | less may be sufficient, or for a more neatly-formatted solution use todone-view which will group completed tasks in to the days they were completed, and supports filtering by the given labels.

What is the extras/ directory?

This directory holds scripts which may have any combination of the following properties: experimental, reliant on non-POSIX tools or languages, or implementing a feature that is unlikely to be widely useful. Contributions welcome.

I can't see any visual difference between completed and uncompleted tasks

Unfortunately the strike-through ANSI escape sequence is not supported in many terminal emulators (in fact, gnome-terminal seems to be about the only one). I have a suggested alternative escape sequence to use you can enable in ~/.sh-todo, which displays completed items in grey.
