[BUG] htmlp and latexp

[BUG] htmlp and latexp

[Dan Davison]

Commit ed6d6760268 removed variables htmlp and latexp from
`org-export-preprocess-string'. Nothing wrong with that, but I think it
has broken export for those using org-special-blocks, which contains

#+begin_src emacs-lisp
(defvar htmlp)
(defvar latexp)
(defun org-special-blocks-make-special-cookies ()
  "Adds special cookies when #+begin_foo and #+end_foo tokens are
seen.  This is run after a few special cases are taken care of."
  (when (or htmlp latexp)
    (goto-char (point-min))
...
#+end_src

I think because those defvars lack a second argument, the variable is
not actually defined, i.e. they're not equivalent to (defvar htmlp nil).

IIuc htmlp and latexp occur occasionally in org code as somewhat
unofficial ways to test "am I in the middle of export?".

They also occur in org-exp-blocks, but in deprecated code, so not a
priority to fix.

Confirmed. Exporting the following example stops with a void-variable 
error in org-special-blocks-make-special-cookies.

--------------------

Some text.

#+begin_sidebar
   Some details left out of the main text.
#+end_sidebar

(Incidentally -- org-special-blocks.el still says it's "not currently 
part of GNU Emacs", but as of Org-mode 7.4 it is, isn't it?)

It's not yet part of GNU Emacs but it will be soon.

Fixed thanks.

Now there is a uniform and official (!) way of getting the backend the
user is currently exporting to: 

  (eq backend 'html)

I fixed them there too.

I was about to make a temporary fix but I see Bastien's just fixed
it. Bastien -- should we give that `backend' variable a name within the
org-* namespace (and maybe defvar it in org.el?) so that it is a more
respectable way to test for "am I doing export now?"? (This issue just
came up in a separate babel thread).

backend is dynamically scoped, so I think there is no need to defvar it
in org.el -- only in org-*-blocks.el, to avoid compilation warnings.

Let me know if you think otherwise.

But it's a good idea to rename it to org-export-backend.  Can you do it?

Hi Bastien,

I was thinking that if it were defvard in org.el, say as

(defvar org-export-current-backend nil)

then any code could use (null org-export-current-backend) to test
whether org is currently exporting or not. Otherwise, the code has to be
certain that it has been called during export if it is going to access
the variable.

For example, babel code can get called both during interactive
evaluation with C-c C-c, and also during export. It might be helpful for
that code to be able to inspect the value of org-export-current-backend
to see what the current context is.

I confirm you this has been fixed 1 or 2 days ago. Just git pull, and you're
gone.

Have you tried recent head?  
Enable stacktrace: M-x toggle-debug-on-error
Also include M-x org-version?

Re: Re: [BUG] htmlp and latexp

[Jeff Horn]

I'm still encountering this bug.

Org-mode version 7.4 (release_7.4.418.g373c)

This looks like an old release, which is odd. I'm using Eric Schulte's
starter kit, and anyway just switched to the org master branch and
pulled down the latest commits. 'make clean', 'make info', and 'make
lisp/org-install.el' were my next steps.

Is it right to take the last 6 chars and search for a commit through
the web interface? It isn't turning up anything, and that string is
starting look familiar to me.

What about M-x org-reload? Or restarting emacs?

M-x org-reload RET (or C-c C-x !)

There is no "htmlp" string in the code anymore, so any bug raising it
tells that there is "htmlp" somewhere in your own snippets.

Could you check that?

Hi, Jeff,

Check if you've got an old version of org-special-blocks somewhere on 
your loadpath. I did, and it kept me running in circles for a bit.

I agree this would be a good idea.  If you have time, please send a

Thanks to Andreas, Christian, Bastien, and Nick. I didn't know about
org-reload, so that bit is handy. Faster than restarting emacs.

This bug is gone now. My backtrace also indicated org-ex-bibtex.el was
the culprit for me.

Here's a patch. I note that Eric S pointed out in a separate thread that
org-current-export-file can be used for a similar purpose.

Incidentally, I would suggest that org-current-export-file and
org-current-export-dir are renamed so that they are within the
org-export-* namespace. There are other areas of Org where I think the
naming should be standardised, notably in org-src.el: the distinction
between org-src-* and org-edit-src-* is unclear IMO. I think this is
kind of important, because in learning emacs one does makes use of these
namespace conventions, e.g. C-h v <initial-letters> TAB. How much change
would there be if we demanded that *all* variables defined in org-foo.el
are named within the org-foo-* namespace?

Thanks a lot for the patch.  I applied a generalized version of it,
using `org-export-current-backend' whenever possible - see last git
repository.

Now one can use `org-export-current-backend' anytime during export
to check the current export backend.

This also reduces the amount of variable we need to pass to the
function.  I've been through the functions which had a "backend"
variable and I think it's safe to always dismiss such a variable
and use `org-export-current-backend'.

Best,

I'm not sure this is Eric's task,

git blame lisp/org-src.el | cut -d' ' -f 3 | sort | uniq -c
    352 Davison
    434 Dominik
      3 Guerry
      9 Rooke
      9 Schulte
      5 Sperber

but Carsten may have a view. I also want to change the customize group of a
lot of those
variables: a lot of the org-src-* and org-edit-src-* variables are filed
in Customize under

Org Structure -> Org Edit Structure

which has to be one of the least intuitive things in the whole of Org!

There's a question of whether we have an Org Src customize group in
addition to the Babel customize group, and how we keep them distinct. In
fact, that may be what has prevented this from being sorted out thus
far.

Any work in this area would be great -- thanks for putting a stab on
