Subject: Feature request and patch - blocked TODO to say BLOCKED
Date: Thu, 1 Jan 2009 17:53:57 -0500 (EST) [thread overview]
Message-ID: <1131.66.30.178.137.1230850437.squirrel@mail.panix.com> (raw)
In-Reply-To: <20090101170227.C707734803@mail2.panix.com>
Motivating incident: I had a todo-type item that contained no tasks
itself, directly, but linked to other tasks. I arranged it this way
in order that those other tasks could be placed neatly in a hierarchy
and not appear as "TODO" in two places. I used the org-depend.el
BLOCKER code to manage this situation. BTW, it works nicely.
But when a task is blocked, the heading is left with no "TODO" marking
at all. That's not so bad for sibling tasks, because there's one
right above it that says "TODO" (or something). But for distant-link
style tasks, IMO it gives a misleading impression that there is
nothing to do.
I request the following:
* Object: One TODO workflow keyword set that relates specially to
"BLOCKER". It would be something like (sequence "BLOCKED" "|"
"UNBLOCKED").
* Behavior: When a C-c C-t change to a heading is blocked, instead of
doing nothing, mark the heading with the first entry in the
blockage workflow keyword set.
* Behavior: Also do so when there is a blocked C-c C-t change to any
heading whose TODO mark is in a state in the blockage workflow
keyword set.
* Behavior: Ordinarily don't offer the blockage workflow keyword set
for C-c C-t and related commands.
I append a patch which does this.
The change mostly affects org.el, because allowing new TODO keywords
requires org.el to know about them, at least in computing some regular
expressions. It was also a lot neater to let org-todo react to
blocked transitions than to try to make `org-depend-block-todo' do it,
which also avoided `org-todo' indirectly calling itself.
Summary of changes
Added 3 variables:
* org-todo-use-blockage-keywords-p :: whether to use this
* org-todo-blockage-keywords :: configurable keywords
* org-blockage-keywords-1 :: internal
Encapsulated part of `org-set-regexps-and-options' as
`org-set-todo-constants'. I had to because it needed to be called
twice, once for normal keywords and once with a flag for blockage
keywords. I used encap-sexp to do it automatically (it's on my site,
http://panix.com/~tehom/my-code/), so no code changed, and I kept that
comment aligned with the regexp.
Made `org-set-regexps-and-options' also process
`org-todo-blockage-keywords'.
Changed the behavior of org-todo and org-depend-block-todo as described
above.
