Re: [O] minimal testing setup for pdf export?

2019-08-30 Thread Tim Cross


To be a little precise, Org mode PDF documents created using the default
Latex classes are not going to meet minimal accessibility standards. The
extent to which they can be accessed using accessibility software will
depend largely on the structure of the underlying PDF. I have not
investigated other workflows for generating PDFs from org (for example,
what happens if you go to some other intermediate format, like HTML or
markdown etc) and then to PDF using a different tool to generate the
final PDF. Likewise, I don't know if some of the TeX pdf generators are
better than others (this is partly why it gets complicated - there are
multiple workflows to generate PDFs from Latex). There are people
working on additional latex packages to address this accessibility
requirement. However, either they are only at experimental status or
require significant configuration and setup or require the author to
manually add additional data, making them inappropriate for org-mode.

With PDFs, the level of accessibility does depend a lot on the structure
of the underlying document. Even PDFs without full tagging can be
reasonably accessible if the structure of the data in the PDF is
straight-forward i.e. not lots of tables, multi-column, lots
of footnotes and internal references etc. If the data flow in the
document is reasonably 'linear', then it isn't too bad. If the document
has lots of embedded postscript or any image like data, that will not be
accessible and will not be tagged adequately. Likewise, I've found stuff
generated in math mode is typically inaccessible.

The various text extraction tools, like pdftotext are able to extract
the text. However, because it cannot determine the structure with any
accuracy, it can tend to be somewhat jumbled and have a bit of
'garbage'. Again, how good/bad this is depends on the underlying PDF
structure.

You might find the following links useful -

https://www.tug.org/twg/accessibility/

https://tug.org/pipermail/accessibility/2016q4/05.html

You might be able to improve the accessibility of PDFs generated from
Latex by adding some of the (mostly experimental) additional packages to
your Org mode setup. However, this will probably have some unfortunate
side effects or corner cases (which is why I don't just recommend adding
these packages as defaults in org itself).

There has been an item on my todo list to experiment with this stuff for
a long time, but I just never seem to get that far down the list. If you
do find some configurations which help make the PDFs more accessible, I
would be happy to try adding them to my setup for further testing. We
may find some additional packages which improve the situation and don't
have unacceptable impact on general org performance and stability. I'm
confident that if we can demonstrate this, having these additions added
to org-mode defaults would be possible.

Okay, orgmode pdf files will be inaccessible for the foreseeable future.
 Has anyone had any luck extracting text however mangled from one of
these with pdftotext or similar tools?  If that's not possible that will
be another good thing to know.

I think the main thing which needs to be in the PDF is structure
'tagging'. Unfortunately, making truly accessible PDFs is the one area
I've found where the 'TeX suite is weak. I was tracking some discussions
about this on  the various TeX and Latex lists and it seems that to add
the necessary information needed to create accessible PDFs requires a
major redesign of TeX internals.

It has been a while since I looked at this, but I do believe there are
some add-on latex packages which can help a bit, but creating PDFs which
meet minimal accessibility requirement tests is currently not possible.

IIRC the speech-disabling feature is not part of the PDF spec. This is
somethinhg added by Adobe (along with other DRM support). This is no
'switch' so to speak in plain PDF documents as the PDF spec predates
considerations like TTS or even accessibility.

most of the books sold on google play books are speech-disabled by
publishers.  The adobe accessibility site has speech-enabled
accessibility examples.  I think it's a matter of a single control that
is either enabled or disabled.  Oh, the IRS has speech-enabled pdf tax
forms anyone can download.  I nearly forgot about that one.  The 1099R
form is a short one so it ought to be pretty quick to find the setting
in one of those forms.

Not sure that org mode can do anything about, since it's LaTeX that produces
the PDF. That said, I'm not sure what needs to be done: what's the difference
between a speech-enabled PDF and a non-speech-enabled one?

It would be helpful if when pdf get exported from orgmode they have

Thank you so much for the detailed instructions. I had a moment this
morning so I updated Emacs, rebooted my laptop, and started to follow your
instructions as closely as possible... and I can no longer reproduce my
problem. I feel like I should be happier than I am! I wonder if perhaps
there was some kind of strange path problem caused by a software update
that I didn't pay attention to.

In any case, I am as always grateful for the efforts of people on this list
-- I learned at least a little bit about latex export and feel that I might
finally be getting a little closer to where I need to be.

Meanwhile, if the issue shows up again I'll be sure to check back in.

Thanks!

Did this get solved? It kind of bothers me to think it hasn't. I also
think this is a case where erring on the side of overwhelming details
would help a lot. Could you start from the beginning with the exact
process using emacs -Q, post the full output of *Messages* and *Org
PDF LaTeX Output*? Like in the above, you post the output of $PWD, but
not what the *Messages* buffer contained from John's code. Maybe they
are the same, maybe they are different, but we can't tell.

Example:
$ cd ~/
$ emacs -Q

M-x org-version
Org mode version 9.1.9 (release_9.1.9-65-g5e4542 @
/usr/share/emacs/26.2/lisp/org/)

C-x C-f pdf-test.org

File contents:
* foo


C-x C-s
C-c C-e l p

$ ls ~/
pdf-test.org
pdf-test.pdf
pdf-test.tex

Alternatively, insert the code from John Kitchin:

Wrote /home/jwhendy/pdf-text.org
org-babel-exp process emacs-lisp at position 8...
Saving file /home/jwhendy/pdf-text.tex...
Wrote /home/jwhendy/pdf-text.tex
Processing LaTeX file pdf-text.tex...
Building pdf-text.tex. Called from /home/jwhendy/
org-compile-file: File "/home/jwhendy/pdf-text.pdf" wasn’t produced.
See "*Org PDF LaTeX Output*" for details

I still don't feel I understand the full nature of your working
directory, what does and doesn't get saved in that directory, etc. I'd
love to help, but am not able to replicate for you!

Thanks,
John

For me, with "emacs -Q", this reliably returns the path from which I
started emacs.

huh.  that was kinda cool... but the value of default-directory seems to be
correct.  However, this helped a bit:

#+BEGIN_SRC emacs-lisp
(shell-command-to-string "echo $PWD")

#+END_SRC

Not sure what's going on here, but this value is the same in a regular
emacs and  "emacs -Q".  is this normal?

 So pdflatex is called and found. Then pdflatex can't find empty.tex.
 That looks like pdflatex is called in another directory than where
 empty.tex resides. How that could happen, no idea.

Re: [O] minimal testing setup for pdf export?

2019-08-27 Thread John Kitchin
that does suggest that pdflatex is getting called somewhere else.

Maybe you can edebug the export function and check the value of
default-directory to see where it is getting called.

You could also try this

#+BEGIN_SRC emacs-lisp
(defun my-build (quoted-tex-file)
  (message "Building %s. Called from %s" quoted-tex-file default-directory))

(setq org-latex-pdf-process 'my-build)
#+END_SRC

It won't build the pdf, but it will tell you in the messages where it was
called from. It might help figure out what is happening.

However, empty.tex is clearly present.  Latex and pdflatex are both in my

Maybe this is a problem with pdflatex?

I blank file is an MWE. It is highly unlikely Org is producing something
