color as module parameter (mkiv)

color as module parameter (mkiv)

[Peter Schorsch]

Hi,

I am trying to pass a tex color as a paramter to a module. I used the
example from the wiki as a base. But as soon I hand over a color
directly it does not work.

Any help is welcome as I am looking forward to hand
in my first module. Are there any rules how and where to hand in a
module for context?

Thanks
P.

--8<---Modul: bgcolor.tex---------------

\startmodule[bgcolor]
\unprotect
\definecolor[grau][s=.35]
\setupmodule[color=grau]
\setupbackgrounds[page][background=color,backgroundcolor=\currentmoduleparameter{color}]
\protect
\stopmodule
\endinput

--8<--tex file itself---------
\setupcolors[state=start]
\definecolor[bordeaux][r=.66]
\usemodule[bgcolor][color=bordeaux]
\starttext
Hello world!
\stoptext

You can expand the value

  \normalexpanded{\setupbackgrounds[…][…,backgroundcolor=\currentmoduleparameter{color}]}

or you can use \moduleparameter

  \setupbackgrounds[…][…,backgroundcolor=\moduleparameter{bgcolor}{color}]

1. You have to place the module in the correct sub folder.

2. Add your module on the modules page on the wiki.

3. Ask Mojca to add it to the context suite.
