Lazy project definitions

Lazy project definitions

[Bernt Hansen]

Hi,

I've been using the definition that all LEVEL 2 tasks are projects for a
long time.  Recently I tried switching to explicitly marked projects
using a :project: tag (or PROJECT keyword) but I really dislike having
to manually mark projects in my task lists.

A project for me is basically any LEVEL 2 task that has one or more
subtasks.

I would like to define my org stuck projects as LEVEL=2/!-DONE-CANCELLED
with an added skipping function that does not consider level 2 tasks if
they have no children.  I can't figure out how to make this work in the
org-agenda-custom-commands using the skipping function but I think it
should be possible.

My goal here is to add 2 custom agenda commands:
  p - show me projects (level 2 tasks not completed with children)
  o - show me other (non-project) tasks (level 2 tasks without children)

I don't want the 'o' - other tasks listed in my stuck projects view
since these are really one-task items and are not a project by my
simplistic definition above.

I've been using everything as a project that is defined at LEVEL 2 for
ages and that works really well for me -- except I want to stop spending
any time dealing with simple (non-project) tasks when looking for next
tasks and stuck projects.  Sure I could manually mark my tasks as
projects but I don't think that should really be necessary for what I
want to do here... and if it could just say a LEVEL 2 task with children
is a project it would work automagically for me without any additional
input.

For simple non-project tasks I don't need to mark them as NEXT to make
them unstuck -- they aren't projects to begin with and I can have
a convenient way to view all of these simple non-project commands in the
agenda using the 'o' custom command.

Is there a way to this?

Thanks,
Bernt

Hi Bernt,

I guess you can use the regexp options, both in the stuck projects,  
and in a skipping condition for an agenda custom command.

In the stuck project definition, adding "^\\*\\{3,\\}" as the 4th  
element should exclude anything that has level 3 or up in the subtree.

for the agenda commands,

    (org-skip-subtree-if 'regexp "\\*\\{3,\\}")

or so should take care of it, am I right?

Re: Lazy project definitions

[Bernt Hansen]

This works:

 ("p" "Projects" tags-todo "LEVEL=2/!-DONE-CANCELLED"
  ((org-agenda-skip-function
    '(org-agenda-skip-subtree-if 'notregexp "^\\*\\{3,\\}"))))
 ("o" "Other (non-project tasks)" tags "LEVEL=2/!-DONE-CANCELLED"
  ((org-agenda-skip-function
    '(org-agenda-skip-subtree-if 'regexp "^\\*\\{3,\\}"))))


Awesome!

Thanks Carsten!

I don't think this will work.  The regexp matches all tasks with level 3
or higher subtrees ... which is all projects so all projects are
considered unstuck.

I need to be able to somehow say a project is not stuck if it doesn't
have a level 3 task (ie. no children) because it's not a project in this
case.

Is there a way to do that?

Bernt

You are right.  Ahh, I wish we had the power of Perl
regular expressions in Emacs.  It would be sooo easy then.
No, I don't see a good way here.

Maybe the best is to completely write your own skipper here.  This
is actually not too hard, see the Appendix A7 for an example.

Thanks for the pointer to the manual.  I've been beating my head against
the wall for hours on this now.  I tried the example from the manual and
have similar results to the description below.

Here's what I came up with as my skip function

,----
| (defun bh/skip-non-stuck-projects ()
|   "Skip trees that are not projects"
|   (let* ((subtree-end (save-excursion (org-end-of-subtree t)))
| 	 (is-project (save-excursion (re-search-forward "^\\*\\{3,\\}" subtree-end t)))
| 	 (has-next (save-excursion (re-search-forward "^\\*\\** NEXT " subtree-end t))))
|     (if (and is-project (not has-next))
| 	nil ; a stuck project, has subtasks but no next task
|       subtree-end)))
`----

and my custom agenda command is 'x' for testing

,----
|  ("x" "Stuck Projects" tags-todo "LEVEL=2-REFILE/!-DONE-CANCELLED"
|   ((org-agenda-skip-function
|     (bh/skip-non-stuck-projects)))))
`----

but this doesn't work at all like I expect.  I lost a bunch of time when
I had the 'stuck projects' selection instead of tags-todo -- it seems
the skip function doesn't do anything useful with the stuck-projects
setting.

My returned list of tasks is still incorrect -- it contains level 2
tasks with no children.  Sometimes it throws an error -- depending on
what buffer is displayed and where (point) is when I run C-c a x.

In this mail buffer I get

so either I'm doing something fundamentally wrong here or there's a bug
somewhere.

Any suggestions are most welcome.  I can't wait to get this new setup to
work! :)

The custom command (and the skip function) works for me when written as
follows:

--8<---------------cut here---------------start------------->8---
(setq org-agenda-custom-commands
      '(("x" "Stuck Projects" tags "LEVEL=2-REFILE/-DONE-CANCELLED"
	 ((org-agenda-skip-function 'bh/skip-non-stuck-projects)))))
--8<---------------cut here---------------end--------------->8---

I made a couple of changes: (a) I quoted the function name and (b) I
changed tags-todo to tags and removed the exclamation point. Both
tags-todo and the exclamation point limited the results to entries with
active states, whereas (if I understand correctly) you are interested in
all level 2 headings.

When I tested the command/skip function on the following tree, only the
first 2nd level entry (** Testing) showed up in the agenda. Is this the
desired result?

--8<---------------cut here---------------start------------->8---
* Example
** Testing
*** Nothing
** Testing two
*** NEXT A todo
** Testing three
--8<---------------cut here---------------end--------------->8---

Best,
Matt

Thanks for this Matt!!  This seems to do exactly what I want.  I had a
bunch of misfires trying to set this up using the example from the
manual but I didn't want 'todo' as the selection criteria since I can't
match LEVEL=2 with that and I assumed that I could use any of the
Choice: values in the custom agenda commands when using a skipping
function.

I'm off to play with this new setup.

Bernt
