section numbers in margin eventually get placed too far left

section numbers in margin eventually get placed too far left

[Sanjoy Mahajan]

This test file

==================================================
\setuplayout[leftmargindistance=0.125in,
  leftmargin=0.625in,
  width=4.75in,
  rightmargindistance=0.25in,
  rightmargin=0.25in]

\setuphead[section][alternative=inmargin]
\showframe

\starttext
\dorecurse{6}{\section{Blah} 
\input tufte
}

\stoptext
==================================================

asks for section numbers in the left margin, separated from the section
title by the leftmargindistance.  It works fine for the first four
sections.  But sections 5 and 6 (on page 2) have the section number
shifted further left from the correct position by roughly 10pt or so.

It seems very sensitive to the layout.  If I change the
leftmargindistance to 0.25in, the section numbers are all placed
correctly.

I noticed the problem on my default context version:

ConTeXt  ver: 2013.05.28 00:36 MKIV current [from the Debian TL2013 pkgs]

It also happens with the live ConTeXt and with vanilla TL2013.  (Though
it works fine with MKII.)

Is this a bug, or just a change in setuphead that I didn't take account of?

It is a bug. ConTeXt sometimes uses the rightmargindistance for the
left margin, which would be correct for a double sided layout, but
is definitely wrong for a single sided document. However, even in a
double sided layout the calculations are not correct. Here a smaller
example. Note that the output is wrong either way, with
\setuppagenumbering commented out or not.

%% \setuppagenumbering[alternative=doublesided]
\setuplayout[rightmargindistance=1cm]
\setuphead[section][alternative=inmargin]
\showframe

\starttext
  \dorecurse{16}{\section{Blah}
    \input tufte}
\stoptext

Hans,

Thanks, that fixes my and Marco's test cases.  Should I wikify, or will
your fix be part of an uncoming beta?

Best,
-Sanjoy

No need to wikify. It was a bug which has already been fixed in the
latest beta.

Hans is too fast!

Note to self: Test every bug candidate also against the latest beta.

I meant that Hans already uploaded the new fixed beta.
