Hello,
I'm asking just in case that there is any PGF guru on this mailing
list, else I will ask on the PGF list.
I have noticed that TikZ terminal for gnuplot is broken (it worked
half a year ago) because of the following definitions:
\def\gpcolor#1{\tikzset{global #1}}
\tikzset{rgb color/.code={\pgfutil@definecolor{.}{rgb}{#1}\color{.}}}
\tikzset{global rgb color/.code={\pgfutil@definecolor{.}{rgb}{#1}\color{.}}}
\tikzset{global color/.code={\color{#1}}}
Example of usage:
\gpcolor{color=gp lt color 0}
\gpcolor{rgb color={1.000,0.000,0.000}}
Clearly the command \color{...} is something latex-specific. The
question is - does anyone know how to rewrite the commands written
above into generic code that will work in all of the three: plain TeX,
LaTeX and ConTeXt?
"Minimal" example:
\usemodule[tikz]
\edef\tikzatcode{\the\catcode`\@}
\catcode`\@=11
\def\gpcolor#1{\tikzset{global #1}}
\tikzset{rgb color/.code={\pgfutil@definecolor{.}{rgb}{#1}\color{.}}}
\tikzset{global rgb color/.code={\pgfutil@definecolor{.}{rgb}{#1}\color{.}}}
\tikzset{global color/.code={\color{#1}}}
\catcode`\@=\tikzatcode
\starttext
\starttikzpicture
\gpcolor{color=red}
% or: \gpcolor{rgb color={1.000,0.000,0.000}}
\draw (0,0)--(10,0)--(10,5)--(0,5)--cycle; % this one should be red
\stoptikzpicture
\stoptext
Thanks,
Mojca
