Dear list,

Motivated by https://tex.stackexchange.com/questions/406892 I wanted to disable page breaks for parts.  This works on all pages, except the first page of a document.  Why?  MWE is below as always.  Reproducible with TL 2017 and latest beta.

Cheers, Henri

\setuphead   [part]   [page=no]

\starttext

\startpart[title=Part One]   \startchapter[title=Chapter One]   \stopchapter   \startchapter[title=Chapter Two]   \stopchapter \stoppart \startpart[title=Part Two]   \startchapter[title=Chapter One]   \stopchapter   \startchapter[title=Chapter Two]   \stopchapter \stoppart

\stoptext

% solution 1:

\setuphead [part] [page=no, placehead=hidden]

\setuptexttexts [\synchronizehead{part}]

% solution 2:

\setuphead [part] [page=no, placehead=hidden]

\appendtoks \synchronizehead{part}% \to \everybeforepagebody

% solution 3 (new in beta):

\setuphead [part] [placehead=section]

This will delay the flush till the next section head gets place. It's still not 100% predictable but it might work out ok in most cases.

Another option, that I posted on Tex.se is: \setuphead[chapter][continue=no] So that the page is not flushed by \startchapter immediate after a \startpart. Aditya
