Hello,

I have a couple questions about TODO items, cookies and export. I am
unable to find anything the manual that seems relevant. Please see the
attached.

TIA,
Leo

I would like to be able to remove the =TODO= cookies, =[1/2]= and =[0/1]=, on export.
How can I do that?

This is because
 *** DONE :B_block:
is actually parsed as a heading with DONE todo keyword and title
":B_block:". Tag is not recognized.

We probably need to fix it, though I am not sure. It is one of the edge
cases about Org parser.

For cookies, just use stat:nil in OPTIONS. See "13.2 Export Settings"
section of the manual.

Ok. I have become addicted to using TODO tags to organize composition of
beamer slides. I often have untitled blocks in the slides, in order to
control the pacing of the presentation.

Thanks for that. I am not sure how I missed it.

Anyhow, it does not work correctly for subtree export (or I am not
understanding something). The title still includes the cookie. See the
attached.

The =DONE= tag and =[1/2]= cookie should be filtered out by
=stat:nil=. Thanks, Ihor.

However, the title is still mangled when exporting just this heading using =C-c C-e C-s l P= on the heading.

With =ox-beamer=, =TODO= markers mangle the output. That looks like a bug to me.
Ihor says this is an edge case.

Marking the subtree with `C-c @' before export does result in the cookie
being removed from the title.

Is there an easy explanation why marking the subtree matters? I.e. why
do

C-c @ C-c C-e C-s l P

and

C-c C-e C-s l P

work differently?

I understand. Just need to figure out the best way to alter the syntax.
We should be careful with such things.

That was a rather interesting edge case that triggered a bug in
org-element.el.

Fixed, on main. It was a core function, so I did not risk bugfix.
