Top-level headers in org-sparse-tree

Top-level headers in org-sparse-tree

[Iris Jackson]

[-- Attachment #1.1: Type: text/plain, Size: 873 bytes --]

Hi,
I recently started using org mode and I really like it.  I have a single
file that contains all information about a project like TODOs, project
specs, user documentation, development notes, etc.  For example, the way I
generate the project specs is to first create a sparse tree matching on the
tag I assigned to the specs, then HTML exporting it.

The problem I encountered is that org-tags-sparse-tree shows top-level
headers even if they don't contain the selected tag.  Is there a simple way
to turn that off?  For example, if I have a top level section called "Bugs",
and it does not contain the "project spec" tag, then I don't want it to show
up in the result :-)

I think this functionality is controlled by org-make-tags-matcher on line
9382 of org.el (version 6.06b), but this function is too intimidating for me
to try to change it.

Please advise.  Thanks!

You can highlight the region you want to export then

M-x narrow-to-region

Do your export and then

M-x widen

to restrict what is included in the export.

Hope that helps.

does the manual at section: "Tag inheritance"
help you?:

------------------------------------------------------------------------
To limit tag inheritance to specific tags, or to turn it off entirely,
use the variable `org-use-tag-inheritance'.

   When a headline matches during a tags search while tag inheritance
is turned on, all the sublevels in the same tree will match as well(1).
The list of matches may then become very long.  If you only want to
see the first tags match in a subtree, configure the variable
`org-tags-match-list-sublevels'.

   ---------- Footnotes ----------

   (1) This is only true if the the search does not involve more
complex tests including properties (*note Property searches::).
-----------------------------------------------------------------------

cheers,
Giovanni

(setq org-show-hierarchy-above nil)

Hi Iris,

Org considers the version of the file with only top-levels shown as  
the most folded version and does not provide commands that will hide  
these.

If the sparse tree exposes an entry deep in the hierarchy, it will  
also show the entire headline hierarchy above it.  In another reply to  
your message, Giovanni has pointed out correctly that the variable org- 
show-hierarchy-above can be used to turn off this feature.  However,  
the top-level headlines are always excluded from this, they are always  
visible.  Maybe you have set up your file in a way that each project  
is a top-level headline?  A way out would then be to demote all these  
to level two under a top-level headline "Projects" or so.  If you then  
turn off `org-show-hierarchy-above', maybe you will get closer to the  
view you did expect.

I would also like to see org-sparse-tree filter top-level headlines by tags.
It seems strange that this behavior would not be consistent... is this a
bug?

Perhaps this can be changed by hooking in some elisp, following
org-sparse-tree…?
