I have added ConTeXt support in the the newest version of tikz-cd (which I just submitted to CTAN and should be available within the next few days). I didn't test it very extensively. Let me know if there is any problems. On 5/25/13, Idris Samawi Hamid ادريس سماوي حامد wrote:

Dear gang,

With a couple of modifications I got tikz-cd (a package to make commutative diagrams for categories and toposes etc. by Florêncio Neves) working in mkiv:

http://texdoc.net/texmf-dist/doc/latex/tikz-cd/tikz-cd-doc.pdf

It depends on the tikz module, already supported in mkiv.

The tikz-cd module is attached, and here is a sample file:

=============== \usemodule[tikz] \usetikzlibrary{commute}

\starttext \starttikzcd %[ampersand replacement=\&] A \arrow{rd} \arrow[yshift=0.5ex]{r}{\phi} \& B \\ \& C \stoptikzcd

\starttikzcd %[ampersand replacement=\&] A \arrow[yshift=1.5ex]{r} \arrow[yshift=0.0ex]{r} \& B \arrow[xshift=0.7ex]{d} \arrow[xshift=-0.7ex]{d} \\ \& C \stoptikzcd \stoptext ===============

A couple of things:

1 I had to comment out line 396 of pgfsys-pdftex.def in the tikz module, or else I'd get an undefined control sequence. It's not needed anyway since that's pdftex.

2 In tikzlibrarycommute.code.tex, line 395 I had to add the option

ampersand replacement=\&

to avoid a TeX error. So you'll have to use '\&' instead of '&' for matrix

arrays.

3 Some LaTeX-specific stuff is commented, and support is added for

\starttikzcd \stoptikzcd

so we get a ConTeXt environment.

I'm hoping someone can volunteer to place this on the wiki, perhaps even set it up on the modules page, with an indication of its proper place in the texmf-modules tree etc.

Any other improvements will also be appreciated. Enjoy!
