Sorry, I couldn't resist, but post a link to:
    http://xkcd.com/1742/

This goes to the
    Anything that "requires only minimal configuration and tweaking"
part :)

I don't have the file tikzlibrarycommute.code.tex on my machine
either. Anywhere. Not in the ConTeXt distribution nor in TeX Live.
That file was only posted to the mailing list by Idris and apparently
nobody ever looked at it or added it anywhere.

(It usually helps to provide a minimal example or a bit more context.
Just saying that something doesn't work is a bit more difficult to
debug.)

If you want to get this work out of the box, it would be super useful
to coordinate with the original author of tikz-cd to add support for
ConTeXt. And if any other patches are needed, we should try to
coordinate with upstream TikZ authors as well. I'm not sure what to do
with "&" though. We could theoretically add that file to the ConTeXt
distribution, but we'll then end up with other people asking why it
doesn't work in TeX Live and I certainly cannot afford to do
unauthorized changes to other TikZ files without getting a formal
approval that something is broken and without at least getting some
patch scheduled for approval by TikZ developers.

So if you want to get that working temporarily, it's probably best to
follow instructions in that email. If you want to get it fixed
properly, we should convince the authors to add support upstream. I
didn't look at the file(s) yet.

Mojca

PS: I have to add that I'm recently experiencing problems syncing with
upstream TikZ sources - CVS (this has been a problem for perhaps two
months or so).

Or the roll-over text: I searched for ConTeXt and commutative diagrams, and this was the only example code I found.

From my side, it was just a test, as commutative diagrams is an example of a math 2D layout.

It would probably be good if ConTeXt supports it out of the box.

The example works:

This file was removed and listed with a URL under different name. So just download it and rename it to tikzlibrarycommute.code.tex, and the example compiles.

There is a tikz-cd package at CTAN:
  https://www.ctan.org/tex-archive/graphics/pgf/contrib/tikz-cd?lang=en

One makes sure to have the file tikzlibrarycd.code.tex, and follows the translation rules in the manual for ConTeXt. In addition to that, one seems to have to replace the apostrophe with "below".

The first few examples in the manual, which compiled with latest ConTeXt:

\usemodule[tikz]
\usetikzlibrary[cd]


\starttext

\starttikzcd
  A \arrow{rd} \arrow{r}{𝜑} \NC B \NR
                                 \NC C
\stoptikzcd

\starttikzcd
  A \arrow[r, "\phi"] \arrow[d, red]
    \NC B \arrow[d, "\psi" red] \NR
  C \arrow[r, red, "\eta" blue]
  \NC D
\stoptikzcd

\starttikzcd
  A \arrow[r, "\phi" near start, "\psi" below, "\eta" near end] \NC B
\stoptikzcd

\starttikzcd
  T
  \arrow[drr, bend left, "x"]
  \arrow[ddr, bend right, "y"]
  \arrow[dr, dotted, "{(x,y)}" description] \NC \NC \NR
    \NC X \times_Z Y \arrow[r, "p"] \arrow[d, "q"]
    \NC X \arrow[d, "f"] \NR
  \NC Y \arrow[r, "g"] \NC Z
\stoptikzcd

\starttikzcd[column sep=tiny]
  \NC \pi_1(U_1) \ar[dr] \ar[drr, "j_1", bend left=20]
    \NC
      \NC[1.5em] \NR
  \pi_1(U_1\cap U_2) \ar[ur, "i_1"] \ar[dr, "i_2" below]
    \NC
      \NC \pi_1(U_1) \ast_{ \pi_1(U_1\cap U_2)} \pi_1(U_2) \ar[r, dashed, "\simeq"]
        \NC \pi_1(X) \NR
  \NC \pi_1(U_2) \ar[ur]\ar[urr, "j_2" below, bend right=20]
    \NC
      \NC
\stoptikzcd

\stoptext

Hello,

I wrote some very simple MetaPost helpers to create commutative diagrams:
