Hello,
can a section head be generated with the number 0 (or less)?
Sometimes I need to prepend a section while keeping existing section
head numbers...
Example:
----
\starttext
\setupheadnumber[chapter][-1]
\chapter{Ch0} % Getting "Ch0" instead of "0. Ch0"?
\chapter{Ch1}
\stoptext
----
Here, "0. Ch0" is not generated, the zero is not displayed; why?
You can't set a negative number for the start of the counter but you can
change the appereance.
\defineexpandable[1]\PreviousNumber
{\number\numexpr#1-1\relax}
\defineconversion[PreviousNumber][\PreviousNumber]
\defineconversionset[zerostart][n,PreviousNumber][n]
\setuphead[chapter,section][sectionconversionset=zerostart]
\starttext
\chapter{First chapter}
\chapter{Second chapter}
\stoptext
Wolfgang
