Hi list

when running the following code

#+header: :file "absolute-distance.pdf"
#+header: :results file drawer :exports results :fit yes :border 0cm
#+header: :headers '("\\usepackage{tikz}")
#+begin_src latex
   \usetikzlibrary{positioning}
   \begin{tikzpicture}
     \node[circle,fill,label=above:$P_1$,node font=\Large] (point1) at 
(0,0) {};
     \node[circle,fill,label=above:$P_2$,node font=\Large] (point2) at 
(3,0) {};
     \draw[latex-latex] (point1) -- (point2);
   \end{tikzpicture}
#+end_src

everything runs fine and a pdf file gets produced. But when I change the 
file header to "absolute-distance.svg" an error occurs and no output 
gets produced. Find attached the tex file and the log of the compilation.

What is the problem here, why is it defining "\pgfsysdriver" in the 
preamble of the tex document. I thought it is converting the produced 
pdf file with imagemagick (or inkscape?) to svg?

Thanks for any clarification.

Cheers Reza

P.S:

My workaround consist in producing a pdf file and convert it with a 
":post pdftosvg(file=*this*)" header call to svg. This is the post block

#+name: pdftosvg
#+begin_src shell :var file="" :exports none :results output
   pdf2svg ${file:7:-2} ${file:7:-5}"svg" && echo 
"[[file:"${file:7:-5}"svg]]"
#+end_src

but it feels a little hacky and cumbersome and it would be nice to 
produce directly svg

I've deleted a group-closing symbol because it seems to be
spurious, as in `$x}$'. But perhaps the } is legitimate and
you forgot something else, as in `\hbox{$x}'. In such cases
the way to recover is to insert both the forgotten and the
deleted material, e.g., by typing `I$}'.

Confirmed.

svg generation takes a completely different code branch compared to pdf
in ox-latex.el. I am not sure why. Hopefully, someone more familiar with
ox-latex and LaTeX in general can chime in.

Just found this in the source [1], maybe it is already fixed?

AFAIU, the news entry is about LaTeX export (ox-latex.el). Here, we are
talking about LaTeX babel backend, which is a different implementation
(ob-latex.el).

In any case, I can reproduce on the latest main.

why is this handled differently, should it at least use part of the same 
infrastructure?
It seems to be a bug then...

It is a part of the same infrastructure, but the LaTeX templates for
html/pdf/svg/tiks export are different for some reason. There is even a
TODO comment in the code saying that things should better be unified. Alas.

Patches improving the situation are always welcome.

Where would I put combined code for ox-latex.el and ob-latex.el?

I do not think that ob-latex code has much to add into ox-latex.
What I was referring to is the giant `cond' form in
org-babel-execute:latex, which produces different LaTeX templates
depending on the output file extension.

The ob-latex templates should probably remain specific to ob-latex since
they are tailored to produce (usually one-page) documents from short
LaTeX snippets.

Yes of course, sorry I confused stuff, the TODO item was referring to 
producing PDF vs SVG not ob-latex vs ox-latex

By setting

     (setq org-babel-latex-preamble (lambda (_) 
"\\documentclass[preview]{standalone}\n")

the tikz file svg generation does run fine. Obviously the part

     \\def\\pgfsysdriver{pgfsys-tex4ht.def}

inside `org-babel-latex-preamble` does not play well with the svg 
generation.


When having a look at the code inside ob-latex.el I also encountered a 
few stuff which made me wondering:

1. png generation is done with the preview code inside org.el 
(org-create-formula-image), there is also a perfectly fine svg preview 
function but this does not get used for the svg extension which does the 
svg conversion without any external tools like inkscape (see 
https://github.com/bzg/org-mode/blob/main/lisp/ob-latex.el#L156 and 
https://github.com/bzg/org-mode/blob/main/lisp/org.el#L3181)

2. there is a tikz extension switch which does insert the code verbatim, 
which in my opinion does create a whole bunch of problems (backend 
dependency issues). Not to mention that it also mimics behaviour which 
is reserved for the header :results (see 
https://github.com/bzg/org-mode/blob/main/lisp/ob-latex.el#L177).

3. there is a html extension switch with an unclear purpose to me (in 
what scenario would you want to produce an html file?). It also has some 
strange (and contradicting) checking if an svg or an html file got 
produced. As far as I can tell this code never gets executed and is 
therefore pointless (see 
https://github.com/bzg/org-mode/blob/main/lisp/ob-latex.el#L181).

4. the whole pdf generation looks like duplicate code which is already 
done in other parts of the code base (ox-latex.el and for the svg 
extension) it ais also not using the variable org-babel-latex-begin-env 
and org-babel-latex-end-env (see 
https://github.com/bzg/org-mode/blob/main/lisp/ob-latex.el#L225).

I don't want to criticize anyone, I just want to find answers for in my 
opinion some strange decisions.

My propositions for refactoring is:

1. use the svg preview code for svg generation (and therefore ditching 
the whole imagemagick headers)

2. remove the whole tikz generation completely

3. remove the whole html generation completely

4. try to merge pdf generation with org.el and ox-latex.el or 
incorporating it into he preview code and 
org-preview-latex-process-alist (this is probably a whole project of it own)

WDYT?

Best,
Reza

Hi, I had this very same question to produce svg from latex src blocks.

First, consider this example :
#+HEADER: :file test1.png
#+HEADER: :exports results
#+HEADER: :results output silent graphics file
#+HEADER: :fit yes :noweb yes :headers '("\\usepackage{tikz}" "\\usetikzlibrary{backgrounds}")
#+begin_src latex
\begin{tikzpicture}[background rectangle/.style={fill=olive!30}, show background rectangle]
\draw[->] (-3,0) -- (-2,0) arc[radius=0.5cm,start angle=-180,end angle=0] (-1,0) -- (1,0) arc[radius=0.5cm,start angle=180,end angle=0] (2,0) -- (3,0);
\filldraw (-1.5,0) circle[radius=1mm];
\filldraw (1.5,0) circle[radius=3mm];
\end{tikzpicture}
#+end_src

When I run it, it does create a test1.png but, it is in fact a svg file
!! This is because, as you noticed, the `org-create-formula-image`
relies on `org-preview-latex-default-process` which is set to 'dvisvgm.
If you set it to 'dvipng, it creates again a regular png file.

Then, I changed the line :
((and (string-suffix-p ".png" out-file) (not imagemagick))
into
((and (or (string-suffix-p ".png" out-file) (string-suffix-p ".svg" out-file)) (not imagemagick))

so that I can correctly create a svg file when I want to and, to create
a real png file (or jpg one), I add the following line to the header :
#+HEADER: :imagemagick yes :iminoptions -density 600

There is also another way to create a svg file with `htlatex` with :

         ((and (string= "svg" extension)
	       (executable-find org-babel-latex-htlatex))
	  ;; TODO: this is a very different way of generating the
	  ;; frame latex document than in the pdf case.  Ideally, both
	  ;; would be unified.  This would prevent bugs creeping in
	  ;; such as the one fixed on Aug 16 2014 whereby :headers was
	  ;; not included in the SVG/HTML case.
	  (with-temp-file tex-file
	    (insert (concat
		     "\\documentclass[preview]{standalone}
\\def\\pgfsysdriver{pgfsys-dvisvgm4ht.def}
"
		     (mapconcat (lambda (pkg)
				  (concat "\\usepackage" pkg))
				org-babel-latex-htlatex-packages
				"\n")
		     (if headers
			 (concat "\n"
				 (if (listp headers)
				     (mapconcat #'identity headers "\n")
				   headers) "\n")
		       "")
		     "\\begin{document}"
		     body
		     "\\end{document}")))
	  (when (file-exists-p out-file) (delete-file out-file))
	  (let ((default-directory (file-name-directory tex-file)))
	    (shell-command (format "%s %s" org-babel-latex-htlatex tex-file)))
	  (cond
	   ((file-exists-p (concat (file-name-sans-extension tex-file) "0x.svg"))
	    (if (string-suffix-p ".svg" out-file)
		(progn
		  (shell-command "pwd")
		  (shell-command (format "mv %s %s"
					 (concat (file-name-sans-extension tex-file) "0x.svg")
					 out-file)))
	      (error "SVG file produced but HTML file requested")))
	   ((file-exists-p (concat (file-name-sans-extension tex-file) ".html"))
	    (if (string-suffix-p ".html" out-file)
		(shell-command "mv %s %s"
			       (concat (file-name-sans-extension tex-file)
				       ".html")
			       out-file)
	      (error "HTML file produced but SVG file requested")))))

you will notice that this is a copy-paste from the html generation with
two major differences :
- for svg generation, do not use the driver
\\def\\pgfsysdriver{pgfsys-tex4ht.def}
but rather
\\def\\pgfsysdriver{pgfsys-dvisvgm4ht.def}
which handles better fonts and probably many other things
- the svg file produced to not have the same format with this driver
  ("0x.svg")

That would be great to reimplement ob-latex.el, at least correct the
first curious behavior when you end up with a svg file although you
wanted a png one.

Hope this helps.

This, and many other oddities are likely related to the fact that org.el
preview code is more up-to-date, while ob-latex have not been changed,
including its assumptions about org.el's LaTeX preview.

I suspect that some features in org.el were implemented
separately, but did not get integrated with ob-latex.

Could you please elaborate?

Well. We do not remove existing features unless there is strong
justifications. See https://bzg.fr/en/the-software-maintainers-pledge/

As for the contradicting checking, it is likely a classic copy-paste
error when html and svg branches of the code got split.

Again, I am not sure here. It is a very old code. My best guess is that
it was developer prior to ox-latex.

The best hint I can provide is
https://orgmode.org/worg/org-contrib/babel/languages/ob-doc-LaTeX.html
that should document some details of the logic.

Criticism is welcome as long as it is aiming to improve Org. No worries.

If you want to dig further, I can also suggest to use git blame and dig
into mailing list messages from Eric Schulte, the original author of
ob-latex.

Note that imagemagick argument does more than you may expect. For
example, one can apply various image effects on the generated file via
imagemagick:

https://orgmode.org/worg/org-contrib/babel/languages/ob-doc-LaTeX.html
>> :imagemagick
>> When not nil the source block is processed to pdf and the pdf is converted with ImageMagick to whatever is given as :file. Thus, the format is not limited to png.
>> :iminoptions
>> This is passed to ImageMagick before the pdf file.
>> :imoutoptions
>> This is passed to ImageMagick before the output file.

That said, I do agree that re-using svg preview generation sounds like
an improvement. But we need to be careful not to remove the existing
functionality.

> 2. remove the whole tikz generation completely
>
> 3. remove the whole html generation completely

I did not see justification why we need to do it other than lack of
ideas why they are useful. For now, I do not think that removing
tikz/html generation is a good idea.

According to
https://orgmode.org/worg/org-contrib/babel/languages/ob-doc-LaTeX.html,
tikz generation can be useful during LaTeX export.

This sounds like a very good idea. I'd merge the preview code from
org.el into ob-latex.

> WDYT?

Improving ob-latex is most welcome. I think that the first step is
incremental refactor. Let's not remove features until we have less
tangled code that is easier to understand.

I've been using the attached patch for the last few years and I've meaning to send it here/start a discussion about ob-latex.el since I used it pretty much daily to write tikz figures in org mode. So I'm glad to see this discussion has been started!

I've found it to be incredibly productive to use babel to develop tikz diagrams as I can make come changes and quickly `org-ctrl-c-ctrl-c` to render them in the same buffer.

I think when I made this patch I had been caught by some of the quirks of the svg export. For example, sometimes I would have some latex equation which I use ~org-latex-preview~ on as I was writing it, but then it would fail to render as mathjax upon html export since I would use some latex package that isn't available under mathjax. So by using ob-latex I could easily fix this by using the ~:file .svg~ header and get a nice html export. However due to the different way of assembling the ~.tex~ file sometimes ~org-latex-preview~ would work but ob-latex wouldn't. I think my use case may be fairly common and so I think ob-latex really should be updated so svg uses the ~org-latex-preview~ code. o

Also I think the ~.tikz~ extension doesn't really make any sense since one really can but arbitrary tex code in such a block, and I think that's why I renamed it in my patch. However I'm now realizing that this evaluation method probably doesn't make much since `:tangle` will already do this, with the added benefit of handling noweb references correctly. So perhaps this should be removed and document using tangling in lieu of ~:file *.tikz~?

This sounds reasonable, but we must not remove it just yet. Instead, we
need to support .tex extension _and_ .tikz extension as backwards
compatibility. For .tikz extension we may also display a warning that it
is obsolete.

Removing this defcustom will be a regression. Maybe we can instead
append it to org-latex-packages-alist? Note that {color} and {tikz} are
not loaded by default in `org-format-latex-header'.

(concat "a" nil "b") is perfectly acceptable. There is no need to supply
empty strings as `concat' arguments.
Can simply use (when fit ...)

I note that `org-export-get-environment' will be ran inside a temporary
file. It means that Org buffer LaTeX export settings for the source
buffer will not affect the return value. I assume that it is
intentional. If so, it is worth adding a comment about it into the code.

This is removing a non-private function. Even though this function is
nothing but trivial, we still cannot remove it without notice.
