Hi!

arggh....

Discerning the driver is really a problem in ConTeXt, at least for a non-context-guru like myself.

As a quick fix, you will have to define the driver yourself by saying

\def\pgfsysdriver{pgfgsys-pdftex.def}

or whatever seems appropriate before tikz/pgf are loaded. That should shut up the (not-working) automatic driver detection.

Does some context-guru on the list happen to know what is the right, official way to find out which backend is used?

Best regardsm Till

This won't work with luatex (but it does compile without error messages) and I cannot (easily) figure out what the correct driver should be...

I have downloaded pgf from http://www.ctan.org/tex-archive/help/Catalogue/entries/pgf.html and unzip base.zip under minimals-beta/tex/texmf-context/tex/context/pgf then $> context test-alan It seems to work minimals-beta Linux luigicasa-laptop 2.6.24-21-generic #1 SMP Mon Aug 25 17:32:09 UTC 2008 i686 GNU/Linux This is LuaTeX, Version snapshot-0.30.2-2008102016, build unknown ConTeXt MtxRun | current version: 2008.10.23 17:32 %% test-alan.tex %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \usemodule[tikz] \setupcolors[state=start] \starttext Hello, world! \blank \begingroup \tikz \draw[thick,rounded corners=8pt] (0,0) -- (0,2) -- (1,3.25) -- (2,2) -- (2,0) -- (0,2) -- (2,2) -- (0,0) -- (2,0); \endgroup \starttikzpicture \draw[fill=yellow] (0,0) -- (60:.75cm) arc (60:180:.75cm); \draw(120:0.4cm) node {$\alpha$}; \draw[fill=green!30] (0,0) -- (right:.75cm) arc (0:60:.75cm); \draw(30:0.5cm) node {$\beta$}; \startscope[shift={(60:2cm)}] \draw[fill=green!30] (0,0) -- (180:.75cm) arc (180:240:.75cm); \draw (30:-0.5cm) node {$\gamma$}; \draw[fill=yellow] (0,0) -- (240:.75cm) arc (240:360:.75cm); \draw (-60:0.4cm) node {$\delta$}; \stopscope \startscope[thick] \draw (60:-1cm) node[fill=white] {$E$} -- (60:3cm) node[fill=white] {$F$}; \draw[red] (-2,0) node[left] {$A$} -- (3,0) node[right]{$B$}; \draw[blue,shift={(60:2cm)}] (-3,0) node[left] {$C$} -- (2,0) node[right]{$D$}; \draw[shift={(60:1cm)},xshift=4cm] node [right,text width=6cm,rounded corners,fill=red!20,inner sep=1ex] { When we assume that $\color[red]{AB}$ and $\color[blue]{CD}$ are parallel, i.\,e., ${\color[red]{AB}} {|} \color[blue]{CD}$, then $\alpha = \delta$ and $\beta = \gamma$. }; \stopscope \stoptikzpicture \stoptext -- luigi

Hello, doing some trivial experiments (though I don't really understand them) ... When fetching pgf from cvs with cvs up -D 2008-05-20 it worked, while with cvs up -D 2008-05-21 it didn't work. I reverthe the version on the garden to the one that locally worked, but it still fails when I now use that version. Maybe I need to clean up some stuff, but that's the diff between the versions when ConTeXt support broke completely. Mojca (Going out to enjoy the sun now ...)
