LaTeX fragments not being generated due to extra * in tikz env

LaTeX fragments not being generated due to extra * in tikz env

[10cadr]

[-- Attachment #1: Type: text/plain, Size: 551 bytes --]

I was trying out the new option tex:dvipng. The HTML result was a image
with the tikz code.

Turns out, debugging and telling the fragment processor not to delete the
files, what org generates for the tikz fragment is:

\begin{tikzpicture*}

Removing the astherisk would make it work without any workarounds.

How I got around this was

#+LATEX_HEADER: \usepackage{environ,amsmath,multicol}
#+LATEX_HEADER:
\NewEnviron{tikzpicture*}[1][]{\begin{tikzpicture}[#1]\BODY\end{tikzpicture}}

Possibly fixing this issue, will make cross formats much easier.

Hello,

Thanks for reporting. Indeed this is an issue that hasn't been fixed
yet. This is the case for most latex environments  

My solution is here
https://www.mail-archive.com/emacs-orgmode@gnu.org/msg129974.html

but consider also the idea behind the star
https://www.mail-archive.com/emacs-orgmode@gnu.org/msg129976.html

I will try to submit a patch soon.

Best regards,
Jeremie

Hi,

I introduced the change that broke the behavior.  The attached patch
seems to fix the issue for me, does it look reasonable?

Thanks,

thibault

Hello Thibault,

Many thanks. This looks like a reasonable trade off for me.

Best regards,
