Tikz calendar: \pgfutil undefined

Tikz calendar: \pgfutil undefined

[Fabrice Larribe]

Hello,

	I have a problem to use the calendar from the Tikz/Pgf module; here is a minimal example:

%---------------------------------------
\usemodule[tikz] 
\usetikzlibrary[calendar]

\starttext
This should works:
\blank
\tikz  \calendar[dates=2000-01-01 to 2000-01-31,week list];
\blank
but this does not !
\stoptext
%---------------------------------------

I'm using MKII (2010-05-24) from TeX Live 2010  (Note however that I had the same problem with TeXLive 2009). The error is when the calendar library is loaded:

! Undefined control sequence.
l.36 \let\tikz@atbegin@day=\pgfutil
                                                 @empty

I have tried the Tikz distribution from TexLive, the latest Tikz distribution from the suport Tikz page, and the distribution from the module made for ConTeXt, but the problem remains. In the past (last academic year, in may), this worked well, but I'm not able to find what has changed.

Thanks for hints and help !
Fabrice L.

The example still works in mkiv. (Minimal distribution, fairly recent)

The following trick solves the problem temporary, but it should be
fixed somewhere in the source if possible. I'm not sure if it is the
fault of ConTeXt or the fault of TikZ:

\unprotect
\usemodule[tikz]
\usetikzlibrary[calendar]
\protect

\starttext

This should works:
\blank
\tikz  \calendar[dates=2000-01-01 to 2000-01-31,week list];
\blank
but this does not !
\stoptext
To me this looks like

This works ! Thanks a lot for your help.

Regarding the post of David Rogers, this seems
to be a problem which depends on the Context and/or
Tikz distribution. I will inform Till Tantau, the tikz/pgf author,
in case he can change something in the Tikz/Pgf package.

Thanks again,
Fabrice L.

I have an impression that he has been very busy for some time now
(there are a few "critical" pending ConTeXt-related problems in CVS to
which he hasn't answered for a really long time now). There are a few
more skilled people on the mailing list though who have the rights to
commit to repository.

It is still worth a try to ask him or maybe to leave a bug report on
sourceforge page. (I CC-ed him in the previous mail without expecting
him to answer.)

Wow, thanks a lot for the fast fix. (I didn't try it out yet, but see below.)

Now, from what I remember ... In minimals we currently have the
version of TikZ that dates back to 2009-11-18. We used to sync with
the latest version from CVS until something broke (in the sense that
TikZ with ConTeXt didn't work at all in some weird cases). Till was
already busy at that time and you didn't yet dare to apply fixes
without his approval, so the issue probably hasn't been solved yet:
    http://thread.gmane.org/gmane.comp.tex.context.devel/1235/

Before we switch back to the latest version of CVS, I would like to
check if everything still works fine or if the patches that Hans sent
a while back need to be applied first.

If anyone else would like to play with the latest version of ConTeXt
and the version of TikZ from CVS, feel free to do so (I'll be away for
a while.) Here's the source that used to break a while ago (I think
that it broke in MKIV only):

\usemodule[tikz]
\starttext
\starttikzpicture
\fill[gray] (1,1) rectangle +(1,1);
\stoptikzpicture
\stoptext
