Latest betas break tikz matrix

Latest betas break tikz matrix

[Mathieu Boespflug]

Hi all,

This code used to compile in versions of context prior to January,
though I can't quite pin down the versions.

\usemodule[t-tikz]
\usetikzlibrary{matrix}

\starttext
\tikzstyle{description}=[fill=white,inner sep=2pt]
\starttikzpicture
    \matrix(m)[matrix of math nodes,
      row sep=3em, column sep=3em,
      text height=1.5ex, text depth=0.25ex]
           {x&y\\
             z&u\\};
    \path[->]
      (m-1-1) edge node[description] {$*$} (m-1-2)
              edge node[description] {$*$} (m-2-1)
      (m-1-2) edge[dashed] node[description] {$*$} (m-2-2)
      (m-2-1) edge[dashed] node[description] {$*$} (m-2-2);
\stoptikzpicture
\stoptext

(compilation error at the bottom of this email)

I thought at first that this was a luatex problem, but I've ruled that
out with the following plain tex file, which compiles just fine in
plain luatex and in plain pdftex:

\input tikz.tex
\usetikzlibrary{matrix}

\tikzstyle{description}=[fill=white,inner sep=2pt]
\tikzpicture
    \matrix(m)[matrix of math nodes,
      row sep=3em, column sep=3em,
      text height=1.5ex, text depth=0.25ex]
           {x&y\\
             z&u\\};
    \path[->]
      (m-1-1) edge node[description] {$*$} (m-1-2)
              edge node[description] {$*$} (m-2-1)
      (m-1-2) edge[dashed] node[description] {$*$} (m-2-2)
      (m-2-1) edge[dashed] node[description] {$*$} (m-2-2);
\endtikzpicture
\end


I have no idea what the error is telling me and what could be causing
it. Any ideas?

Many thanks,

Mathieu

Could be due to the change in catcode of &. Try adding \donknuthmode.

Hi Aditya,

> Could be due to the change in catcode of &. Try adding \donknuthmode.

It doesn't make any difference if I put the \donknuthmode just before
\starttikzpicture. But If I put it before the \usemodule[tikz], then I
get another error:

Package pgfbasematrix: Error! Single ampersand used with wrong catcode.

Re: Latest betas break tikz matrix

[Mathieu Boespflug]

Hi all,

just as a followup and for the mailing list archives, the solution is
to use both Aditya's suggestion to turn on \donknuthmode, as well
replacing the & signs with their interpretations, namely
\pgfmatrixnextcell. Thank you Aditya for the suggestion.

Regards,

Mathieu

that's a strange error ... if pgf knows that the catcode is 'wrong' it 
could deal with it i guess

umm, i can’t seem to get it to work. i use the mkiv minimals…

no combination of \donknuthmode, \nonknuthmode, \pgfmatrixnextcell and
“replace ampersand=foo”, that i tried, seems to work.

can anyone give me a minimal example of a working tikz matrix in a context
document? (preferrably something that prevents me from littering everything
with “\pgfmatrixnextcell”)

thanks,
philipp

One way around this is to re-read part of tikz module code under the right 
catcode regime (ideally this should be done by t-tikz). I still cannot get 
& to work, but using \& is a reasonable shortcut.

Here is a working example:

\usemodule[t-tikz]
\usetikzlibrary{matrix}

\unprotect
\ReadFile{pgfmodulematrix.code.tex}
\protect

\starttext
\tikzstyle{description}=[fill=white,inner sep=2pt]
\starttikzpicture
     \matrix(m)[matrix of math nodes,
       row sep=3em, column sep=3em,
       ampersand replacement=\&,%% AM: Added this.
       text height=1.5ex, text depth=0.25ex]
            {x \& y\\
             z \& u\\};
     \path[->]
       (m-1-1) edge node[description] {$*$} (m-1-2)
               edge node[description] {$*$} (m-2-1)
       (m-1-2) edge[dashed] node[description] {$*$} (m-2-2)
       (m-2-1) edge[dashed] node[description] {$*$} (m-2-2);
\stoptikzpicture
\stoptext

A slightly more robust solution is to load the attached module instead of 
t-tikz. (It also patches \usetikzlibrary). However, I cannot figure out 
what is the expected catcode of & inside a tikz \matrix. So, you will 
still need to use amserand replacement=\&.

Note that this sets the catcode of ! to other (as expected by tikz). In 
the past, circuittikz has some troubles with the catcode of !.

Thank you both!

We should get the TikZ devs to accept patches already. does anyone know
anyone who has CVS access?

Apart from Aditya’s hack, I’d also like to see Joseph Wright’s
hack<http://tex.stackexchange.com/questions/27952/cmyk-context-colors-in-tikz/27955#27955>for
ConTeXt’s CMYK colors in TikZ. Maybe we should create a module from
user-created TikZ hacks that make it work better with ConTeXt, and link to
it on ConTeXtgarden?

PS: Aditya, does your module provide everything you’d expect? like
\tikzstyle, \usetikzlibrary[something], \tikz\node{};, …? I don’t exactly
know the inner workings of plain TeX…
