Support tikz-cd diagrams

[rjraya]

In my study of category theory I often use tikz-cd diagrams (but please note that any other encoding of diagrams in latex would be good for me). It seems that anki does not support this diagrams at the moment. I wonder if there is a way of either:

1. Import tikz-cd diagrams in a format that anki can read
2. Convert them to pictures and import those pictures to anki (so I guess related to the issue #2).

[TentativeConvert]

This should work out of the box as long as you remember to load tikz-cd with \usepackage{tikz-cd} (and any other packages you might be using) in the preamble. See section 4.1.1 Preamble of the documentation for instructions how to edit the preamble in Anki.

Here is the example card I tried:

% -- coding:utf-8 -- % LATEX PREAMBLE --- needs to be imported manually \documentclass[12pt]{article} \special{papersize=3in,5in} \usepackage[utf8]{inputenc} \usepackage{amssymb,amsmath} \usepackage{tikz-cd} \pagestyle{empty} \setlength{\parindent}{0in} \newcommand{\detail}[1]{{\scriptsize(#1)\par}~} \newcommand{\refs}[1]{{\scriptsize\textit{Refs: }#1\par}\hfill.}

%%% commands that do not need to imported into Anki: \usepackage{mdframed} \newcommand{\tags}[1]{\paragraph{tags: }#1\bigskip} \newcommand{\xfield}[1]{\begin{mdframed}\centering #1\end{mdframed}\bigskip} \newenvironment{field}{}{} \newcommand*{\xplain}[1]{\begin{mdframed}\texttt{#1}\end{mdframed}\bigskip} \newenvironment{plain}{\ttfamily}{\par} \newenvironment{note}{}{} % END OF THE PREAMBLE \begin{document} \tags{basic-category} \begin{note} \xfield{def: Euler function} \begin{field} \begin{tikzcd} F(S) \arrow[d, "\alpha"] & F(R) \arrow[l, "F(\pi_1)"] \arrow[d, "\gamma",dashed] \arrow[r, "F(\pi_2)"] & F(T) \arrow[d, "\beta"]\ S & R \arrow[l, "\pi_1"] \arrow[r, "\pi_2"] & T \end{tikzcd} \end{field} \end{note}

\end{document}

and here is the preamble of the card type to what is imported (basic and reversed):

% -- coding:utf-8 -- % LATEX PREAMBLE --- needs to be imported manually \documentclass[12pt]{article} \special{papersize=3in,5in} \usepackage[utf8]{inputenc} \usepackage{amssymb,amsmath} \usepackage{tikz-cd} \pagestyle{empty} \setlength{\parindent}{0in} \newcommand{\detail}[1]{{\scriptsize(#1)\par}~} \newcommand{\refs}[1]{{\scriptsize\textit{Refs: }#1\par}\hfill.}

%%% commands that do not need to imported into Anki: \usepackage{mdframed} \newcommand{\tags}[1]{\paragraph{tags: }#1\bigskip} \newcommand{\xfield}[1]{\begin{mdframed}\centering #1\end{mdframed}\bigskip} \newenvironment{field}{}{} \newcommand*{\xplain}[1]{\begin{mdframed}\texttt{#1}\end{mdframed}\bigskip} \newenvironment{plain}{\ttfamily}{\par} \newenvironment{note}{}{} % END OF THE PREAMBLE \begin{document}

Still there is an error:

Does the file compile outside of Anki? If so, perhaps your Anki installation is using a different version of tikz-cd from the one you use natively? (The syntax for labels on arrows changed between different versions of tikz-cd.)

In any case, this does not look like a problem related to LaTeX-Note-Importer.

Just to confirm, the file compiles outside of Anki on TexStudio. I will check the version of tikz-cd used by Anki.
