Hello all,
In this very minimal example,
#+begin_src org
,#+select_tags: wanted
,* headline :notwanted:
some text
,** subhead :wanted:
more text
#+end_src
exporting exports the whole tree under /headline/. I can see why but it
is arguably the wrong thing to do. If /notwanted/ hasn't been selected,
I would have assumed that all the contents under that headline would be
ignored during export.
My problem is that I want to export a document where certain headlines
(but not all) are included *and* within these, some subheadlines are
also included but not all. I would be specifying one or two tags for
selection depending on the specific export case.
I can achieve what I want by commenting and uncommenting headlines but
this is very clumsy and error-prone for my use case.
I guess I simply want to confirm that the above noted behaviour is
indeed what is expected from org. If so, I will find a work-around.
Thanks,
eric

Based on the docstrings for org-export-select-tags and
org-export-exclude-tags, this looks expected.
It does not look possible to exclude a heading and include a subheading
under it. It is possible to include a heading and exclude some
subheadings though you need a wanted tag in the parent, and notwanted
tags in the subtrees, and to declare the exclude tags.
#+EXCLUDE_TAGS: notwanted
I am surprised you can use comment like this. It looks to me like
commenting a tree makes all the subtrees in it not export too.
I could see somehow an org-export-before-processing-hook function that
deletes headlines and content you do not want, but it will mess with the
outline, e.g. if you delete "* headline" but leave "** subhead".
I thought I would be able to comment headlines with a hook function like
this, but I could not get it to work. Maybe it is a local problem though.

I think I was unclear. My confusion is that a tree (rooted at a top
level headline) that I do not want exported is nevertheless exported if
a subtree within that tree has a "selected" tag. I would have thought
the higher level heading would take precedence.

Yes, it is. Again, I obviously didn't explain myself well. I have
resorted to commenting out whole trees (rooted at headlines) to avoid
them being exported because a sub-tree has the selected tag.
In any case, I have found a workaround by inverting my tag usage.
thanks,
eric

This does not sound right to me.
This org file:
#+BEGIN_SRC org
,#+select_tags: wanted
,#+exclude_tags: notwanted
,* headline :notwanted:
some text
,** subhead 1
,** subhead2 :wanted:
more text
#+END_SRC
should not have any thing to export.
In contrast:
#+BEGIN_SRC org
,#+select_tags: wanted
,#+exclude_tags: notwanted
,* headline :wanted:
some text
,** subhead 1
,** subhead2 :notwanted:
more text
#+END_SRC
will export headline and subhead1.
At least, that is what I see.

Yes, and it works. However, if I don't explicitly specify "notwanted"
as excluded, the whole file is exported. I guess I don't understand the
meaning of "select_tags": I would like this to specify those trees to be
exported only if the given tags are present. I would expect the
behaviour to be the same whether I specify excluded tags or not when
selected tags are given, other than exclusion of subtrees within
selected trees.
But I guess my understanding is completely wrong. And re-reading the
documentation doesn't make things clearer for me. There seems to be a
gap between selected and excluded tags which is, to me, ambiguous. If
nothing is specified for either, the documentation implies default
values (:export: and :noexport: respectively). However, the behaviour
is not consistent with this as, if I do not specify any selected or
excluded tags, the default behaviour is to export everything.
I guess I could look at the code to see what the underlying logic really
is. For another day, when I have some time -- it's start of term and
I'm doing the headless chicken impression getting material ready for the
students.
Anyway, with the proper combination of both select and exclude tags, I
have managed to get what I want.
Thanks,
eric

This is what select tags do, but the tree starts at top-level. Any tree
that _contains_ a select tag is exported as a whole. See
`org-export--selected-trees'.
You want to use select tags to get parts of trees, i.e. sub-trees. For
example,
* H1
* H2
** SH1 :wanted:
** SH2
*** SSH1 :wanted:
would become morally equivalent to
* SH1 :wanted:
* SSH1 :wanted:
This is not possible.
I had a patch for that, but I never got to apply it because it seemed
very hackish. Also, you can do the same in a hook, where a function
would delete any entry not tagged "wanted" prior to export.

Yes.

But I don't. What I had expected is that if the tree is not selected at
the top level, then it should not be selected at all regardless of
sub-tree heading tags. However, if a sub-tree has a selected task, the
whole tree is selected. I expected nothing.
But this is fine. I now understand the behaviour and can achieve what I
want with careful combinations of tags.
Thanks,
eric
