Boxed items don't like sidefloats

Boxed items don't like sidefloats

[Giuseppe Bilotta]

Hello all,

here's a test document:

================
\setuppagenumbering[alternative=doublesided]

\newbox\testbox

\starttext

\setbox\testbox\vbox{%
\placefigure[outer,none,fit]{}{%
  \framed[width=.2\hsize,height=.2\hsize,offset=none]{}%
}%

\startitemize
\item some test
\item \input knuth
\item \input tufte
\stopitemize
}

\box\testbox

\page

\setbox\testbox\vbox{%
\placefigure[outer,none,fit]{}{%
  \framed[width=.2\hsize,height=.2\hsize,offset=none]{}%
}%

\startitemize
\item some test
\item \input knuth
\item \input tufte
\stopitemize
}


\box\testbox
\stoptext
============

As you may notice, items think the placefigure refers to all
of them, so that if a particular item is bigger than the
figure height, it will wrap correctly around the
(inexistent) box, otherwise it will just side it.

Interesting, the same thing does *not* happen when not going
through a box, but typesetting things directly in the page.
However, for my application I need to typeset the sidefloat
and the itemization in a box, so I hit the bug ...

Suggestions?

Hi Giuseppe,

you can use ConTeXt's stream mechanism.

\setuppagenumbering[alternative=doublesided]

\usemodule[streams]
\definestreamlayer[giuseppe][width=\textwidth]

\newbox\giuseppe

\starttext

\startstreamlayer[giuseppe]
\placefigure
  [outer,none,fit]
  {}
  {\framed[width=.2\hsize,height=.2\hsize,offset=none]{}}

\startitemize
\item some test
\item \input knuth
\item \input tufte
\stopitemize
\stopstreamlayer

\vbox{\placestreamlayer[giuseppe]}

\page

\startstreamlayer[giuseppe]
\placefigure
  [outer,none,fit]
  {}
  {\framed[width=.2\hsize,height=.2\hsize,offset=none]{}}

\startitemize
\item some test
\item \input knuth
\item \input tufte
\stopitemize
\stopstreamlayer

\vbox{\placestreamlayer[giuseppe]}

\stoptext

Wolfgang

Ah, excellent, it works perfectly, thanks a lot! Of course,
I'm still curious about the reason why a standard vbox
wouldn't do it ...

sidefloats hook into the output routine and that does ot work in a box; 
streams intercept the page stream (nasty but neat); expect more of that 
kind of stuff

I've noticed that specifying width= in the streamlayer
definition is not enough to force the stream width. If the
width is different from the textwidth, I have to use
something like

\startsetups streamlayer:giuseppe:settings
  \overloadtextwidth\gbwidth
\stopsetups

I would have expected

\definestreamlayer[giuseppe][width=\gbwidth]

to handle this automatically though.

Makes sense.

> kind of stuff

You know, seeing how streams work made me think about an
extension I was considering for Alpeh: \pageboxnumber, being
255 by default but which could be changed at runtime,
choosing which box was used to build the MVL. I originally
thought about it because my mathematically aesthetical sense
complained that box 255 had to be used in e-TeX and
Omega/Aleph as well (the last box number in each system made
more sense), but now that I see your streams idea I think it
would have been a useful addition.

(Oh yes, I should really get back to Aleph. I see that
luatex builds on that too. I must say that I'm glad to see
that the project has been taken over when I disappeared
without a trace :P)

this will become configurable in luatex

well, luatex renders aleph kind of obsolete -)

also, luatex has pdf output (also for aleph stuff)

Ah, good to know.

Yeah, I got that impression :)

This is a very good thing. I have big hopes up for it. Also,
as part of my “getting back into the loop”, do you think
there's some where/some how I can give a hand?

well, mplib ... apart from going megapost (your speciality) 3d will be 
added and since you're the mathemagician who can think in 6 dimensions ...

mplib will be linked into luatex

Ah, this is something I can more probably involve my
university with. While my advisor doesn't care much about
TeX per se, numerical things are much more of its taste.
