No, ppchtex is not dead...
I would like to use color.
1. color= and rulecolor= does not appear to be implemented (mkiv)...
2. how can one change the color of the bonds?
3. using \color[red]{} causes the text to be offset.
"minimal" example:
\setupcolors[state=start]
\usemodule[chemic]
\starttext
\startchemical
\chemical[ONE,SB,Z0][C]
\stopchemical
\startchemical
\color[red]{\chemical[ONE,SB,Z0][C]}
\stopchemical
% text "C" is offset...
\startchemical
\chemical[ONE,SB,Z0][{\red C}]
\stopchemical
% OK, but I would like to draw the bonds as well in red.
\startchemical[color=red]
\chemical[ONE,SB,Z0][C]
\stopchemical
% "C" is red in mkii, black in mkiv
\startchemical[rulecolor=red]
\chemical[ONE,SB,Z0][C]
\stopchemical
setting happened at the outer level (ok, that's broken now but we can
fix that later); so now, each formula must have the settings; when i
have time i'll make a mkiv variant so that we can upgrade (i don't want
interference with mkii since that version is also used in latex and we
don't need to upgrade that)
\def\setchemicalattributes
{\scratchdimen\@@chemicalrulethickness
\def\chemicalattributes
{withpen pencircle scaled \the\scratchdimen\space
withcolor }%
\doifelsenothing\@@chemicalrulecolor
{\edef\chemicalattributes{\chemicalattributes black}}
{\edef\chemicalattributes{\chemicalattributes
\MPcolor{\@@chemicalrulecolor}}}%
\startMPdrawing
drawoptions (\chemicalattributes) ;
\stopMPdrawing}
