Hi,
There was a recent question about what appeared to be commutative diagrams, and
I wanted to reply saying that one option is to use tikzcd module. However,
testing showed that it fails.
This is what tikzlibrarycd.code.tex does:
% ConTeXt-specific stuff
\pgfutil@IfUndefined{starttikzpicture}{}{%
\def\starttikzcd{\tikzcd}
\def\stoptikzcd{\endtikzcd}
\tikzcdset{
every matrix/.append code={%
\def\NC{\pgfmatrixnextcell}%
\def\NR{\pgfmatrixendrow}}}
}
where
\def\tikzcd@[#1]{%
\tikzpicture[/tikz/commutative diagrams/.cd,every diagram,#1]%
...}
So, it fails because \tikzpicture is being called with wrong catcodes. It can
be fixed in the same manner as we patched tikzpicture as shown by the following
MWE:
\usemodule[tikz]
\usetikzlibrary[cd]
\permanent\protected\def\starttikzcd%
{\starttikzinput
\hcontainer\bgroup
\tikzcd}
\permanent\protected\def\stoptikzcd
{\endtikzcd
\egroup
\stoptikzinput}
\starttext
\startformula
\starttikzcd
x \arrow[d] \NC A \arrow[d] \NC D \NR
y \NC B \NC D \NR
\stoptikzcd
\stopformula
\stoptext
What is the best way to go about this? I can try to ask the
Should we include a wrapper for tikzcd (as we do for circuitikz) or should I
try to push a patch upstream.
BTW, why do we need a \hcontainer in the above code?
Aditya
