Hi,
I have encountered a really strange bug in textbackground.
Occasionally, textbackground colors the whole page instead of just the
text between \starttextbackground and \stoptextbackground. This
happens only when I am using module mag-01 and have
\setuptyping[style=\ttx\setupinterlinespace] set.
Attached is the minimal example that I could make.
Tested with beta
ConTeXt ver: 2006.04.18 22:36 fmt: 2006.4.23 int: english mes: english
For this test, ConTeXt ver: 2006.04.10 20:04 fmt: 2006.4.23 does
not give any problem, but similar problem occurs at some other place.
If it is important, I can try to make a minimal file to reproduce the
problem with latest stable release.
Thanks,
Aditya

\usemodule[mag-01]
\setuptyping[style=\ttx\setupinterlinespace]
\definetextbackground
[example]
[width=\textwidth,
background=color,
backgroundcolor=lightgray,
frame=off,
leftoffset=1em,
rightoffset=1em,
location=paragraph,
after={\blank[small]},
before={\blank[small]}]
\def\ShowExample
{\startexample
\typebuffer
\stopexample
\getbuffer}
\starttext
Suppose you want to number only a few equations by a subformula and have
normal formula numbering for others, it can be achieved by
\startbuffer
\def\CNR{\decrementnumber[formula]\NR} %Continued NR
\placeformula
\startformula \startalign
\NC c^2 \NC = a^2 + b^2 \NR[+][a]
\NC a^2 + b^2 \NC = c^2 \CNR[+][b]
\NC d^2 \NC = e^2 \NR[+]
\stopalign \stopformula
\stopbuffer
\ShowExample
\section{Intertext}
Sometimes you want to place some text between two parts of math equations
without disturbing equation alignment. \CONTEXT\ provides \tex{startintertext}
environment to achieve this.
\startbuffer
\startformula \startalign
\NC A_1 \NC= \left| \int_0^1 (x^2 - 3x)\, dx \right|
+ \left| \int_1^2 (x^2 -5x + 6)\, dx \right| \NR
\startintertext
Take limits of both integrals
\stopintertext
\NC \NC = \left| \frac{x^3}{3} - \frac{3}{2} x^2 \right|_0^1
+ \left| \frac {x ^3}{3} - 7 \frac{5}{2} x^2 + 6x \right|_1^2 \NR
\NC \NC = \left| - \frac{7}{6} \right| + \left|\frac{14}{3} -
\frac{23}{6}\right| = \frac{7}{6} + \frac{5}{6} = 2 \NR
\stopalign \stopformula
\stopbuffer
\ShowExample
\section{Aligned Matrices}
\CONTEXT\ provides \tex{startmatrix} for generic alignment mechanism.
\startbuffer
\startformula
\startmatrix
\NC A \NC B \NC C \NR
\NC a \NC b \NC c \NR
\NC 1 \NC 2 \NC 3 \NR
\stopmatrix
\stopformula
\stopbuffer
\ShowExample
\stoptext

there is a dangling line of the background due to a break
\def\ShowExample
{\startexample
\nobreak
\typebuffer

Thank you. This takes care of it.

i adapted the textbackground macros as well as the mp code to catch the border case (this whole background stuff is rather tricky code)

Is this included in the latest release (ConTeXt ver: 2006.04.22
10:41)? The previous test case does not run correctly. See results at
http://www.eecs.umich.edu/~adityam/context/pagebreak.tar.gz
> (this whole background stuff is rather tricky code)
A manual \nobreak in the definition makes sure that everything works,
so this is not really important.

hmm... need to wait till texsync starts syncing with the new release.
