Hi,
I desperately need runtime defined colors (state dependent) for my macros. The macros are used with different graphic styles, which is the reason why I want to avoid any style dependent part inside them.
To give you an example. I need something like this
\color [{\StateDependentColor[stateA=green,stateC=blue,whatever=yellow,...]}]
If flag 'stateA' is true at runtime, then color 'green' is used (and so on; order is significant).
I have written such a macro, but sadly it crashes when used inside \color or \definecolor. Tried to debug it, but this is my first experience with the trace commands (probably not the best example to start with). Sigh, still so much to learn.. :)
Any hints are welcome.
I'm not quite sure I understand what you're trying to do, so this is a shot in the dark: instead of low-level trickery, you could use ConTeXt modes:
\startmode[A] \definecolor [mycolor] [g=1] \stopmode
\startmode[B] \definecolor [mycolor] [r=1] \stopmode
You can then set \enablemode[A] in your file or pass the mode on the commandline: texexec --mode=A
Thanks Thomas for your help. I can do this without low-level trickery, but this would mean one or two (fore|backgroundcolor) additional macro(s) per building block (>20) for every graphic style (currently 2; more to come). This makes about 60 stupid little macros..... nope. I think that in some special cases I must do this anyway (where the color is choosen from a combination of states), but most times a general macro will do. I will try to get it run this weekend (have to learn TeX debugging first). But I wouldn't be surprised if this is the easier part of the problem. We will see :) Greetings, Peter
