[O] Export visible part of tree to latex

[John MacCallum]

Hi all,

I have an org file with this structure:

* head                                                                          
                                   
** topic 1                                                           :topic:    
                                   
*** foo                                                                         
                                   
**** some foo                                                           :foo:   
                                   
*** bar                                                                         
                                   
**** some bar                                                           :bar:   
                                   
** topic 2                                                                      
                                   
*** foo                                                                         
                                   
**** some other foo                                                     :foo:   
                                   
*** bar                                                                         
                                   
**** some other bar                                                     :bar:

and I would like to collect all entries with the tag foo and export them to a 
latex file.  I have the variable org-show-hierarchy-above set to nil, so f I 
run C-c \ "foo", I get this:

* head...                                                                       
                                   
**** some foo                                                           
:foo:...                                   
**** some other foo                                                     
:foo:...  

which is exactly what I would like to export.  But when I go to export using 
C-c C-e v l, the resulting latex file doesn't contain any of the entries below 
the top ("head") level:

The html export does work as expected, however, and produces a nice bulleted 
list of entries tagged "foo".  Also, the latex export works fine if I use it to 
export the entire file instead of just the visible portion.

As an alternative, I tried creating a project by setting the 
org-publish-project-alist variable like this:

(setq org-publish-project-alist                                                 
                                   
        '(("foo"                                                                
                                   
                :base-directory "~/toys/org"                                    
                                   
                :base-extension "org"                                           
                                   
                :publishing-directory "~/toys/org"                              
                                   
                :publishing-function org-publish-org-to-pdf                     
                                   
                :section-numbers nil                                            
                                   
                :select-tags ("foo")                                            
                                   
                :include ("org.org")))) 

and exported using C-c C-e X "foo", which works ok, but the value of the 
variable org-show-hierarchy-above is not respected, so I end up with a latex 
file that has the entire hierarchy above the foo-tagged entries, which is not 
what I want.

If someone could point me in the right direction, I'd really appreciate it.

Also, I'm using GNU Emacs 24.50.1 from the git repository built a few weeks 
ago, and the latest org-mode from git built yesterday.

Thanks in advance,
JM
