page float in columnset

page float in columnset

[Vit Zyka]

Hi wizards,

let me go back to columnsets. I try to place a float spanning the whole 
page area. When doing that the running text placing exactly one page is 
completely and forever lost! Please see example:

-----------------------------------------
\setuplayout[grid=yes]
\showgrid

\starttext
\startcolumnset
   \dorecurse{4}{#1 --- \input knuth \blank\endgraf}
   \placefigure[here]{none}{%
     \framed
       [width=\makeupwidth,height=\textheight,offset=overlay]
       {Page float.}}
   \dorecurse{10}{#1 --- \input knuth \blank\endgraf}
\stopcolumnset
\stoptext
-------------------------------------------

Switching here -> page, tops, ... does not solve the problem.
The similar behaviour is observed when a float has one column width and 
fit the whole column height.

Is there some solution or another way how to do that and preserve the text?

Thanks
Vit

you were the guy running an ancient context, wasn;t it? 

works ok here (although i admit that this mechanism is a bit tricky; a solution is to make the graphic .99 textheight (in columnset sone runs into rounding error problems

Yes on my machine, not so ancient on an notebook; but your context is 
old too since you sent me off-list the same wrong result ;-)

Please, closely look on the paragraph numbering. In the second paragraph 
sequence the number 2, 3, and 4 are missing, number 1 and 5 are partialy 
missing -> total one page is lost.

> works ok here (although i admit that this mechanism is a bit tricky;

i believe; it is one context's advantage over plain or latex, so it can 
be a new challenge to decrease the number of bugs...

> a solution is to make the graphic .99 textheight

even .98 not ;-) No, it does not solve. Text stops to disappear when 
there is enough space for at least one line. But I would like only 
figure on the page. Not with one or more line text. Yes one can add some 
imaginary empty line, but it is agly (and difficult if some \vadjust 
inside a paragraph is needed).

> (in columnset sone runs into rounding error problems 

Perhaps but loosing text it the worst variant - no error, no warning, no 
graphical mark. You can easily overlook such disaster.

ah ... your persistent ... 

you can try this: 

\OTRSEToutput
  {\dontcomplain % new, get rid of overfull message (to be sorted out)
   \doloop
     {\OTRSETnaturalflush
     %\OTRSETstartnextpage %  no
      \OTRSETdoflushfloats % actually belongs in \flushsavedfloats (but goes wrong)
      \OTRSETcheckfreelines
      \ifsomefreecolumncells \exitloop \fi}%
   \OTRSETchecksidefloat}

tricky patch so please test extensively! (for the moment put this in your local copy of cont-loc.tex or maybe in your doc)

yes, slow but persistent (hopefully not annoying...)

Huraaaaa!!! Great. It works! It works! It works! It works at least for:

- full page float: [page|here](\textheight,\makeupwidth) in simple example

- full column float: [here](\textheight,\OneColWidth) in simple example

- does not change page break and/or float positions in 160 pages 2 or 3 
columnsets document with about 330 floats!

- and more over: preserves any text in this doc!

It does not work for \startcolumns (not columnsets) but
- seems to me it is another problem (break one more line in each column 
that is appropriate to \textheight)
- the behaviour is exactly the same with or without the new patch

Thank you, Hans, very much! I do not know how to reciprocate with... 
(you sometimes suggest to buy a beer but I am afraid of your being 
drunken if everybody who is helped by you buys to you a beer :)

ok, i'll add the patch to page-set.tex

so you have the world record now of the most complex doc made with column sets; makes me confident that this (tricky) mechanism is becoming workable

...I can add fluent marginal column where the main text spans 2

:-) That is a good news. Bad news is that I am working on this since 
March; on September it was to be done, but was not. Even worst, it has 
not been finnished yet - currently in the proofreading stage. 
Fortunately it is not a commercial job. But my friends are wondering 
what I can so long to do at it and they consider me to be crazy.
