Custom todo-like thing in agenda?

[Marcin Borkowski]

Hi all,

I was wondering whether something like this is possible.  (Well, I'm
pretty sure it is, what I don't know whether I'm competent enough to
pull it off...)  I'd like to be able to create a special agenda view
(or block in a "normal" agenda, this shouldn't make much difference,
since I may use block agenda instead of the usual C-c a a), in which
the lines would behave much like TODOs, with the exception that their
source would not be an Org file, but something else.  In my case, it
would be a web todo-like service, with the possibility of extracting
info (like the deadline and such) using some command-line curl
invocation.  Then, I could (rather easily, I guess) write some Elisp
to parse this info, and (here the hard part - at least for me -
begins) somehow insert it in the agenda buffer.

Of course, I could also just generate an "intermediate", temporary org
file, using curl -> parsing -> buffer -> save and include it in the
agenda.  This would most probably speed up the process of generating
the agenda (which is a plus).  However, I'd like another
functionality: I'd like to have the `t' command to send some
information to the web service I'm using.

Where should I start?  Is there anything even remotely similar to what
I'm trying to achieve so that I could analyze its source, for
instance?  Is the "intermediate org file" idea a reasonable one (the
more I think about it, the more I like it)?

If I decide to go the "intermediate-file" way, where could I hook into
the agenda generation, so that it is e.g. created only once each day
(to save time) or on explicit demand (this part is easy, I guess -
just some command to create it and a key in org-agenda-mode-map...)?
Should I advise org-agenda or is there some hook run *before* agenda
generation?  Should I advise org-todo?  (Just looking at its source
made my head spin...)  Should I use some hooks for the todo behavior I
described?  (I found org-trigger-hook and
org-after-todo-state-change-hook; frankly, I don't really get why both
are there...

Sorry for being a bit vague - this is still a concept in a preliminary
stage, and it's 4:07 am here;)...

Best,

This seems interesting for sure.

I don't have more knowledge than you on such a topic; however, if I had
to really look into that, I'd start by taking a look at the following:

- `org-debbugs.el' package from Michael Albinus

- Bugzilla integration from John Wiegley
  (see https://gist.github.com/jwiegley/472120)

HTH -- and please publish any step you make!

Best regards,
  Seb

One possible idea would be to check out org-weather-metno
from https://github.com/ruediger/weather-metno-el
