A few thoughts ...
(1) Having a WBS (work breakdown structure) coding may provide sufficient dependencies between the tasks. Child task depends on parents. Sibling task depends on earlier tasks.
(2) WBS coding could be simple one word dotted numbers ...
(3) The todo.txt clients can display the task properly sorted and indented. And possibly make the sort permanent in the todo.txt file.

This is a can of worms.The dependencies themselves are not a problem, but what lies next can be challenging. For example, you might want to think about:- Can one task depend on multiple other tasks?- Is dependency circularity allowed? Probably not.- Can you easily determine whether a task is blocked? Probably not, because it will involve walking a chain of dependent tasks to the end.- Can you easily identify blocking tasks? Not easily because it involves looking at the reverse relationship - if "1" depends on "2", then "2" is blocking "1", but "2" contains no metadata to that effect. This also involves walking the chain.- Dependencies imply that a tool can then be used to determine things like critical path.- Can a task depend on a project? Vice versa?Nice job with 2.9 everyone!

This works just fine to organize your project where:
Having some fancy plugin to indent and auto-complete one task seems like overkill when you could use a sort and solve this without adding any complexity.On Wed, Apr 11, 2012 at 3:33 AM, Danilo Zanatta <dan.zanatta@...> wrote:

capture a task that can't be completed right now because some other task
is blocking it, I'll either add it directly to tickler.txt ("todo.sh
addto tickler.txt task...") if I'm at my computer, or add it to todo.txt
via the Android client and move it later, typically during my end of day
As tickler tasks become unblocked, I move them back to todo.txt.

as long as you avoid auto-archiving, direct edits, and let the CLI do the
archiving (the Android client isn't able to do that yet, anyway), you can use
the task number, provided that you adapt it when archiving.

wait, unwait, listblockers, lswait, blockerview, depview
and hooks into do and archive actions. It's probably best described by one of my
I don't use it extensively (I currently have 7 blocked tasks out of 400), but it

trumps extensibility (except for the CLI). It would be difficult to keep all
implementations of an extension compatible, anyway. So, any such extension
requires you to chiefly use the CLI.
