Would it be possible to use latexmk or rubber or one of the other
"intelligent" LaTeX compilers?  That /should/ automatically make the
compilation as short as possible.

Hi Leo,

In general, one would communicate with a subprocess through its input
and output, and to do that in elisp please see (elisp) Input to
Processes.

Hello,

Thank you for pointing me in the right direction. I've created another 
init file just for async-export, and not only have I got it to work, but 
it's also quite a lot faster than it used to be.


All that remains now is to find a way to re-write my function. My 
knowledge of elisp if fairly limited, and I don't see how to communicate 
with the background process other than by writing the value of my 
toggle-variable to a file. I guess I could also make a modularise 
async-init.el and control which module is loaded from the main init.el.


At any rate, thank you for your prompt reply.

Best,

The background process doesn't use whatever configuration is loaded in
current Emacs. Instead it loads a configuration file. See
`org-export-async-init-file'.

You may also use local variables in your document, or switch async
configuration files.

The background process doesn't use whatever configuration is loaded in
current Emacs. Instead it loads a configuration file. See

[O] Bug: Modifying org-latex-pdf-process doesn't modify the async export behaviour

[Leo Vivier]

Hi,

I've encountered an issue trying to write a function to toggle between 
two org-latex-pdf-process states (short & long). The function works as 
intended when using synchronous export (the PDF is created with the 
appropriate number of steps), but it doesn't work with asynchronous 
export (org-latex-pdf-process isn't grabbed past the first run).


Here's my function:
# --
(defvar zaeph/org-latex-pdf-process-mode)
(defun zaeph/toggle-org-latex-pdf-process ()
  "Toggle the number of steps in the xelatex PDF process."
  (interactive)
  (if (or (not (bound-and-true-p zaeph/org-latex-pdf-process-mode))
  (string= zaeph/org-latex-pdf-process-mode "short"))
  (progn (setq org-latex-pdf-process '("xelatex -shell-escape\
-interaction 
nonstopmode\
-output-directory 
%o %f"

   "biber %b"
   "xelatex -shell-escape\
-interaction 
nonstopmode\
-output-directory 
%o %f"

   "xelatex -shell-escape\
-interaction 
nonstopmode\
-output-directory 
%o %f")

   zaeph/org-latex-pdf-process-mode 'long)
 (message "XeLaTeX process mode: Long"))
(progn (setq org-latex-pdf-process '("xelatex -shell-escape\
  -interaction nonstopmode\
  -output-directory %o %f")
 zaeph/org-latex-pdf-process-mode 'short)
   (message "XeLaTeX process mode: Short"
(zaeph/toggle-org-latex-pdf-process)
# --

I've tried appending (org-reload) to my function, but it didn't work.
I've also tried modifying org-latex-pdf-process on a fresh emacs session 
prior to any async export, and I can confirm that it grabs the latest 
state of org-latex-pdf-process. I'd surmise that async export has a 
process running in the background, but I don't know how to force it to 
reload.


Would you have any idea?

Thanks.
