Hello,
I'use extensively context to write my lecture notes and for all of my printing needs.
For my students, I've made some lecture presentations in color, and I print them in black&white, with four pages on one page for the handout.
I would like to compute a correct Table of contents according to the handout : so to divide the current page number by four to get a correct page number for the handout.
\def\ChapterPrefix#1{\the\numexpr#1/4 \relax} \setupcombinedlist[content][level=1] \setuplist[chapter][after=,before=,numbercolor=yellow,numbercommand=\underbar,pagecommand=\ChapterPrefix]
That doesn't work, and I've some difficulties to figure how computation is performed in e-TeX...
Could you help me to resolve this issue ?
A very dirty hack:
\setuppapersize[A6][A6]
\let\normaltranslatednumber\translatednumber
\def\translatednumber[#1]% {\number\numexpr(\normaltranslatednumber[#1]+1)/4\relax}
\starttext
\completecontent
\dorecurse{12} {\chapter{Chapter #1} \dorecurse{#1}{\input knuth\par}}
\stoptext
Wolfgang
