Hi all,
I'm still getting the hang of org-mode, so the problem might be me :-)
That said, there seems to be a misfeature in the way org-mode archives
subtrees when using multiple #+ARCHIVE lines in one file.
Consider an org file _testofarchive.org that looks like:
#+ARCHIVE: ./_testofarchiveARCHIVE.org::* First
* First 2007
#+ARCHIVE: ./_testofarchiveARCHIVE.org::* Second
* Second 2007
#+ARCHIVE: ./_testofarchiveARCHIVE.org::* Third
* Third 2007
With point on the * Second 2007 headline, invoke C-c C-x C-s. After
the archiving, the file looks like
#+ARCHIVE: ./_testofarchiveARCHIVE.org::* First
* First 2007
#+ARCHIVE: ./_testofarchiveARCHIVE.org::* Second
* Third 2007
The problem is that the #+ARCHIVE line governing the * Second 2007
headline is left behind, and the one governing the * Third 2007
headline is taken away, not as desired. (What I would like to have
happen is that the * Second 2007 tree gets filed away, and the
following #+ARCHIVE line remains to affect future archiving of * Third
2007.)
As I understand org-mode, this is a consequence of taking a subtree of
level n to continue until a headline of level m, m <= n occurs or
EOF. But, unless I am missing something, I don't see how the multiple
#+ARCHIVE lines technique can be made to work with this definition,
short of including dummy level 1 headlines in the file to `protect'
the #+ARCHIVE lines. (I mean something like inserting
* To make org happy
#+ARCHIVE: ./_testofarchiveARCHIVE.org::* Third
between * Second 2007 and * Third 2007.)
Am I missing something about how these #+ARCHIVE lines are intended to
be used?
It seems to me that a possible fix would be to look at the end of any
subtree that is being archived, and leave behind an #+ARCHIVE line (or
perhaps uninterrupted block of #+ lines) that terminates the tree
being archived.
And, in case it seems like I am trying to do something daft, I'd like
to explain my aim briefly. I have a file teaching.org. Each course for
the coming term is a top-level headline with course name and term
details (e.g., * Intro to Phil 20072008). As I teach some of the same
courses in successive terms and academic years, I'd like my
teachingARCHIVE.org file to have top level headings for each course
title I teach and to send the archived subtrees of particular
offerings of a given course title to the appropriate heading in my
teachingARCHIVE.org. So, at the end of the year * Intro to Phil
20072008 would become a second level heading under * Intro to Phil,
and likewise for * Intro to Phil 20082009 should I teach that next year.
This isn't crucial (I can live without the archiving mechanism sorting
the course subtrees for me). But, I can't see how to use the #+ARCHIVE
lines as currently implemented.
Thanks and best,
Brian vdB

Hi all,
Sorry for the self-reply, but after posting I expanded the parameters
of my google search, and thought a follow-up worthwhile.
I posted woes regarding #+ARCHIVE lines getting archived or left
behind. And I suggested a dummy headline to ameliorate the problem:

In a thread from 2007-03 started by
<http://lists.gnu.org/archive/html/emacs-orgmode/2007-03/msg00084.html>
a similar problem was discussed regarding #+CATEGORY lines. Carsten
<http://lists.gnu.org/archive/html/emacs-orgmode/2007-03/msg00089.html>
said that what I called `dummy' headlines was one of two possible
work-arounds he could see. What didn't come up was the suggestion I made:

Now I am curious as to if this is unworkable. Carsten, if it is, would
you mind briefly sketching why? (Time permitting, of course.)

Hi Brian,
In principle the solution you propose is workable of course.
You are, in fact, not the first to think of this: for example
the file outline.el in Emacs 22 states:
;;; Todo:
;; - subtree-terminators
;; - better handle comments before function bodies (i.e. heading)
;; - don't bother hiding whitespace
This is an issue in many types of files that would like to use
outline to get a structured view on a file. For example
Programmers often write comments *before* a function definition.
I find it hard to envision a *clean* implementation, however.
Problems with this approach are:
- Lets say we say that comments before a headline so not belong
to the entry before it. Do they belong to the entry after it?
If I archive the entry after it, should I move the comment then?
- What if I have a normal entry with some text in there, and I decide to
comment it out, just temporarily. All of a sudden this text no longer
belongs to the entry, when I move the entry up or down, using
structure editing commands, how should I decide in a safe way what
comment does and what dow not belong to an entry?
The current outline implementation is at least clean in the sense
that it is totally predictable what will happen if you issue
certain commands.
I still believe that the best work-around it to have top-level
sections in your file, make the #+ARCHIVE lint the first line *inside*
the section, and then have your TODO items as level 2 entries below it.
If you are going to structure your document anyway in a way that
requires multiple archives, why not reflect this structure also
with top-level headlines?
- Carsten

Hi Carsten,
Thanks for taking the time to shed some light. I'm not surprised that
the line of attack I suggested has been considered before.

OK, I start to see why you are reluctant to change the current
behaviour. Thinking this through, I see a real risk of explosion of
special cases and that would indeed likely get ugly.

Well, that's what I am doing. I've a teaching.org where each course
for the coming year is a level 1 headline. When the year is over, I
want to archive each course level 1 headline as a level 2 subtree of a
level 1 headline in my teachingarchive.org. The thought is that as I
teach say Intro to Logic over the years, each iteration of the course
when active will be in my teaching.org. When the term is done, each
will course tree will get archived under a Intro to Logic level 1
heading in my archive file. So, the end result in the archive would be:
* Intro to Logic
** Intro to Logic Fall20072008
** Intro to Logic Fall20082009
* Intro to Philosophy
** Intro to Philosophy 20072008
** Intro to Philosophy 20082009
etc.
The only way I can see to do it with #+ARCHIVE lines would be to have
my teaching.org look like
* Heading setting ARCHIVE line for following tree
* Intro to Logic Fall20072008
* Heading setting ARCHIVE line for following tree
* Intro to Philosophy 20072008
etc.
That makes for ugly clutter, IMHO. (The problem is acute in my
intended case, as each level 1 heading needs its own ARCHIVE line.)
But, since the archiving will be done for the entire course tree and
at most twice a year, doing it by hand would be fine.
Thanks for shedding more light and for enduring the long posts :-)
Best,
Brian vdB

I would say that this only requires a litte creative restructuring,
and to give up the idea that in teaching.org, courses must be level 1.
In teaching.org:
* Intro to Logic
#+ARCHIVE: archive settings for logic
** Fall200072008
* Intro to Philosophy
#+ARCHIVE: settings for philosophy
** FALL20072008

Hi Carsten,
Sure that would work, if only I could get past the tunnel vision
induced by my first conception of how to structure things ;-)
Thanks for the discussion.

Man, that is beautifully said. Nothing to add.
I' ll put that on a sign above my desk.
