Is this also the cause of problems I noted with heading placed into the margin, as in the example below?
no, unrelated, try this:
\setuphead [section] [after={\strut\blank[-2*line,samepage,disable]}, command=\SectionCommand, distance=0pt]
\define[2]\SectionCommand{\inleft{XXXXXX}}
That was fine until it ran into \setupwhitespace with a non-zero value. Fiddling with the after key \blank does not appear to help.
\define[2]\MarginHead{\inmargin{#1\\#2}} \setuphead [section] [command=\MarginHead, distance=0pt, after={\strut\blank[-2*line,samepage,disable]}] %% With no \setupwhitespace, or any \setupwhitespace setting that %% results in zero interparagraph whitespace, all is well. %setupwhitespace [none]% okay %setupwhitespace [fix]% okay %% With non-zero interparagraph whitespace, the heading separates %% from the text \setupwhitespace [line]% bad \starttext \startchapter[title={Weisman}] \input weisman\par \input weisman \startsection[title={Thuan}] \input thuan\par \input thuan \stopsection \stopchapter \stoptext
you can always skip back whitespace or add 'nowhite'
Well, nowhite is a start, but the solution is still a way off. Meanwhile, the following works for non-grid layouts with reasonable values for \setupwhitespace, although perhaps somebody can come up with a more eloquent way to write it:
\newdimen\SectionHeadSkip \SectionHeadSkip\dimexpr-2\lineheight-\parskip\relax \setuphead [section] [command=\SectionCommand, distance=0pt, after={\strut\blank[\the\SectionHeadSkip,samepage,disable,nowhite]}, ] \define[2]\SectionCommand {\inmargin{#1 – #2}}
A better formulation (better because it preserves any stretch that might defined by \setupwhitespace): \setupwhitespace [big] \newdimen\Parskip \Parskip\dimexpr-\parskip\relax \setuphead [section] [command=\SectionCommand, distance=0pt, after={\strut\blank[\the\Parskip,-2*line, samepage,disable,nowhite]}, ] \define[2]\SectionCommand {\inmargin{#1 – #2}} As with the previous, \Parskip has to be redefined if \setupwhitespace changes, so it is probably best left until after \starttext, when the body font is established.
When enabling grid layouts, the number of lines needs to be adjusted.
No, it is not stable on grid layouts. Sections that have a figure placed as the first thing will be a line off.
Floats that appear as the first thing after a heading may present problems, especially with larger values for \setupwhitespace. (The default, with no location= specified, is pretty good, but when location={left,force} or such, there is often an unwanted offset from the header. and page breaks still appear between the heading and figure at times, despite the samepage setting for \blank.)
So, this is quite fragile. It requires careful checking of every heading, and manual tuning when one breaks. Not a desirable solution, but at least it is possible.
Still fragile. -- Rik Kabel
