keep intermediary tex from latex preview

keep intermediary tex from latex preview

[Edgar Lux]

Hello, this has possibly been asked before, but (OMFG) I haven't been able to find it (sorry). How can I keep the .tex file used to generate a latex preview from an Org buffer (or file)? (the closest that I got was =org-latex-logfiles-extensions=). I can usually see such file in =/tmp= if the preview fails. Thanks.

Org 9.4.6
Emacs 28.2 x86_64-pc-linux-gnu

In short no.
And we are also in the process of refactoring the preview system:
https://list.orgmode.org/orgmode/87lek2up0w.fsf@tec.tecosaur.net/

You may, however, try to narrow the buffer to the latex fragment of
interest and then export body to latex via C-c C-e dispatch.

Looks promising!
Is the functionality which I mentioned there as well? (get the .tex for the preview even in absence of error)

Currently, no. Could you elaborate on why you’re interested in this
functionality?

All the best,

When using xetex and dvisvgm, an equation like this:

    \(µp\)

will render as p (see attached file), most likely because my configuration is wrong. I don't know how I fixed it for another buffer, but then I restart and--without knowing what happened--the "no-µ" behaviour is back.  Also (I am not saying that I have a test case), some times the PDF is produced correctly, but the preview isn't. Also, in the past, I have noticed that the (failed) .tex for a (wrong) preview is slightly different. When the equation is definitely wrong, I get to see the .tex in =/tmp/=, but the Emacs + LaTeX configuration is so versatile that I get an output even if I type =\({µp\)= (which is a good feature in most cases). Right now, 

1. setting (setq org-latex-pdf-process '("cp %f /tmp/debug.tex"))
2. reloading Org (org-reload) and
3. creating a new Org buffer 
4. preview or export to PDF 

does not produce =/tmp/debug.tex=. I hope that I was able to describe my situation. Right now, I will look into =org-latex-packages-alist= again. I want to say that I appreciate Emacs and Org very much. Thank you.

By the way, using Ihor's suggestion, I was able to debug the issue. There is nothing wrong with my configuration. The issue is that the font cannot deal with that symbol, and LaTeX just skips it. Still, it would be convenient not to have to create a separate .tex to debug the preview. Thanks!

AFAIR, the new preview system will record possible issues with previews
and mark them appropriately in a tooltip.

Timothy, will it also be the case for LaTeX warnings?

I think currently we scan the stdout for error messages but not warnings.

Of course, this is an area that could be expanded in the future (and I hope will
be, it would be nice to have the errors in something like flymake rather than
tooltips IMO, it’s just too much extra work for now).

All the best,
Timothy

In this specific case, it was recognized as an error.  Here is an image
of the result and the tooltip message with the new LaTeX preview system.

I typed \(μp + 1\) because getting a screenshot of the tooltip with just
the rendered `p' was tricky.
