Hi, I've been trying to have a similar example working for hours, specifically I was trying to follow https://orgmode.org/worg/org-contrib/babel/languages/ob-doc-LaTeX.html
Could you provide more context because if I run emacs -Q here, with the example provided by OP, and type C-c C-c, I just get "no org-babel execute function for latex!".
So I guess it might have required a little more work than what I've just described.
Here is the setting I've used:
This in my dot-emacs.org file:
#+begin_src emacs-lisp
(with-eval-after-load 'org
(add-to-list 'org-latex-packages-alist '("" "stmaryrd" t))
(add-to-list 'org-latex-packages-alist '("" "tikz-cd" t))
(add-to-list 'org-latex-packages-alist '("" "amscd" t))
(add-to-list 'org-latex-packages-alist '("" "mathtools" t))
(add-to-list 'org-latex-packages-alist '("" "unicode-math" t))
;; (add-to-list 'org-latex-packages-alist '("" "breqn" t))
(add-to-list 'org-latex-packages-alist '("" "thisisastupidtestfile" t))
(setq org-latex-create-formula-image-program 'dvisvgm) ;; probably only this line is relevant with the matter at hand
(setq org-format-latex-options
(plist-put org-format-latex-options :scale 0.80)))
#+end_src
With this, when I put the following in some org file and type C-c C-x C-l I immediately get a org-latex-preview of the tikz snippet:
\begin{tikzpicture} %
\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=1mm];
\end{tikzpicture}
Now If I use the following and type C-c C-c, I never get anything in multiple ways:
Note that I've also tried with imagemagick...
#+name: test_plot_png
#+header: :exports results :file test.svg
#+header: :dvisvgm yes
#+header: :fit yes :noweb yes :headers '("\\usepackage{tikz}")
#+begin_src latex :file test.svg
\begin{tikzpicture} %
\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=1mm];
\end{tikzpicture}
#+end_src
Many times a pdf is generated in the /tmp/ directory but that pdf is gibberish. When I go from the latex file to the pdf using pdflatex, only gibberish pdf is generated, no relation with the image that should be generated.
If instead I use lualatex, the pdf is correctly generated.
Anyway, I've been experimenting for hours, and I have no idea how to have the thing working.
I also used that code someone gave me:
#+begin_src emacs-lisp
(set-variable 'org-preview-latex-process-alist
'((dvipng :programs ; Was here originally.
("latex" "dvipng")
:description "dvi > png" :message "you need to install the programs: latex and dvipng." :image-input-type "dvi" :image-output-type "png" :image-size-adjust
(1.0 . 1.0)
:latex-compiler
("latex -interaction nonstopmode -output-directory %o %f")
:image-converter
("dvipng -D %D -T tight -o %O %f"))
(dvisvgm :programs ; Was here originally.
("latex" "dvisvgm")
:description "dvi > svg" :message "you need to install the programs: latex and dvisvgm." :image-input-type "dvi" :image-output-type "svg" :image-size-adjust
(1.7 . 1.5)
:latex-compiler
("latex -interaction nonstopmode -output-directory %o %f")
:image-converter
("dvisvgm %f -n -b min -c %S -o %O"))
(imagemagick :programs ; The recommended "new" way.
("latex" "convert")
:description "pdf > png" :message "you need to install the programs: latex and imagemagick." :image-input-type "pdf" :image-output-type "png" :image-size-adjust
(1.0 . 1.0)
:latex-compiler
("lualatex -interaction nonstopmode -output-directory %o %f")
:image-converter
("convert -density %D -trim -antialias %f -quality 100 %O"))))
#+end_src
No luck at all there neither.
BTW, when I do C-c C-c on the OP example, after having evaluated
#+begin_src emacs-lisp
(org-babel-do-load-languages
'org-babel-load-languages
'((latex . t)))
#+end_src
No pdf, no output, only an empty latex file generated in /tmp
Bottom line, I'd really like to know how this hole thing is supposed to work.
org-preview latex working perfectly fine though.
Note: The reason I want to have this working is that I want to export to html. Plain latex formula are displayed very very well using mathjax. But TiKz things are not working.
So even though I've got a near wysiwyg in emacs, I can't have that exported to html.
What I'd like to have is plain latex formulas exported to mathjax and tikz diagrams exported using the SVG image.
Initially my setting wasn't even using imagemagick, only dvisvgm.
Also it seems we have three ways to do the exact same thing:
org-latex-preview which works perfectly with minimal effort on my box,
the C-c C-c thing,
and the org-html-export-to-html thing.
Each using independent workflow. Though probably not completely independent though.
My emacs is master from a month ago.
Cheers,
Chris
