Hello list! I was reading the following:
https://wiki.contextgarden.net/Style_Alternatives
I wanted to figure out how to make a simple module. However, there's a
point in the example below which I don't understand
% macros=mkvi
\startmodule[look]
\unprotect
\writestatus{loading}{ConTeXt User Module / look}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\installnamespace {look}
\installcommandhandler \????look {look} \????look
\appendtoks
\setuevalue{\currentlook}{\do_look{\currentlook}}
\to \everydefinelook
\unexpanded\def\do_look#id{%
\edef\currentlook{#id}%
\dosingleempty\do_do_look%
}
\def\do_do_look[#parms]#content{%
\begingroup
\iffirstargument\setupcurrentlook[#parms]\fi
%This handles style and color
\uselookstyleandcolor\c!style\c!color%
#content%
\endgroup%
}
\protect %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\stopmodule
What have I to do if, instead of "color" or "style", I want to use another
keyword, as "dummy" and get its value? Something like
\definelook[lol][dummy = blabla]
\lol{words}
%e.g. words \emph{blabla} or something similar
so "lol" is a word, a number or whatever. I've read something about command
handlers, but I'm having a hard time trying to understand them. Thank you
in advance!
