    As requested a few times, xypic diagrams are now available as well as Tikz diagrams. An example is currently at the Sandbox. One writes \begin{xymatrix} ... \end{xymatrix}. This is not quite as in LaTeX, but is easier to implement currently.

    One can also write \begin{xymatrix@=5em}...\end{xymatrix} to resize both rows and columns, or the same with @R (resp . @C) instead of @ to resize only rows (resp. only columns).

    We need to add this to the HowTo page eventually.

    [Edited this to reflect changes in syntax from first draft. ]

  1. Here is the github commit.

    Much appreciated! If it isn't done by the time I get home tonight I'll update the how-to page.

    I've added a subsection for xymatrix, the bent arrows don't seem to be rendering on my screen though. It also didn't like the code

    \xymatrix@C+2pc{A \rtwocell^f_g{\alpha} & B}

    for a 2-cell diagram, but I need to add \usepackage[2cell]{xy} and \UseTwocells in my preamble to get them to render properly which might be related.
  2. Thank you very much for adding to the HowTo!

    I’ll look into those issues as soon as I get the chance, probably this evening.

  3. Fixed both now. The reason that the curved arrows example was broken is that the LaTeX standalone package chops them off. I have introduced a workaround, described at the HowTo. I have also changed the syntax for an xymatrix block.
