Hi,

how do I access the current chapter number and the number of chapters (including appendixes; after the first run)?

I’d like to setup a chapter color like

\definecolor[ChapterColor][   s=1,v=1,   h=360*\namedstructurevariable{chapter}{number}/\numberofchapters, ]

and use it for a thumb index...

(I can’t access the wiki ATM; downforeveryoneorjustme.com says it would be just me.)

Ok, I can access the wiki via Tor and found \somenamedheadnumber{chapter}{current} \somenamedheadnumber{chapter}{last} or \someheadnumber[chapter][current] \someheadnumber[chapter][last] What’s the difference? And even if I use \definecolor within a setup, I get the same color for every chapter – how and where must I delay expansion? \usemodule[visual] \startsetups[MyChapterSetup] \definecolor[MyChapterColor][h={360*\somenamedheadnumber{chapter}{current}/\somenamedheadnumber{chapter}{last}},s=1,v=1] \definecolor[fakerulecolor][MyChapterColor] \setuphead[chapter][color=MyChapterColor] \stopsetups \unexpanded\def\MyChapter#1{ \setup{MyChapterSetup} \color[MyChapterColor]{#1} } \setuphead[chapter][page=no,textcommand=\MyChapter] \starttext \dorecurse{20}{ \chapter{\fakewords{1}{5}} \fakewords{10}{50} } \stoptext Hraban
