columnset balancing

columnset balancing

[Vit Zyka]

Hello Hans,

appologize my boring again with the same question about columnset 
balancing. But I would like to know what is the current stage of this 
feature. Seeing the code it seems to me some work in this direction was 
done but due to very complex and tricky stuff I am not able to 
recognize, how far from the goal it is.

Actually, what is my goal design?
+ two column layout
+ float spanning one or two columns
(both perfectly fullfilled by columnsets)
- each chapter head spans two columns
(it assumes stop columns, balancing, continuing on the same page without 
pagebreak, put chapter head, start columnset on the rest of the page)

It is feasible or I will have to abjured this idea?

Thank you for your responce in advance.
Vit

Hans it is great! I have two next questions:

1) Am I missing something or columnsets do not provide balancing?
----------------------------------------
\definecolumnset[two]  [n=2,balance=yes]
\starttext
\startcolumnset[two]
    \dorecurse{6}{\input knuth \endgraf}
\stopcolumnset
\input zapf \endgraf
\stoptext
-----------------------------------------

2) Footnotes with settings \setupfootnotes[location=columns,rule=on]
between \columnset do not draw rule. I discover it is due to missing
\vbox. So this solve this problem for me, but it is not elegant and I do
not know if it can caused some side effect:
-------------------------------------------
\def\MyBeforeFootnote{\vbox\bgroup\blank}
\def\MyAfterFootnote{\egroup}
\setupfootnotes[
   location=columns,rule=on,rulethickness=.4pt,
   before=\MyBeforeFootnote,after=\MyAfterFootnote,
]
\unprotect
\def\normalnoterule
   {\endgraf %% <--- add
    \ifvmode
      \color
        [\noteparameter\c!rulecolor]
        {\vrule
           \!!width .2\hsize
           \!!height\noteparameter\c!rulethickness
           \!!depth \zeropoint}%
      \kern\strutdepth
    \fi
    \endgraf %% <--- add
}
\protect

\definecolumnset[col][n=2]

\starttext
   \startcolumnset[col]
     \input knuth
     \footnote{Donald E. Knuth}
   \stopcolumnset
\stoptext
------------------------------------------------

you can do that with 'manual balancing'

the problem with automated balancing in this model is that it's near to 
impossible (never say never with tex, but its definitely messsy code) to combine 
this with the advanced float and area placement features; so, your flow will be:

- typeset article
- determine balance requirements
- setup balancing
- retypeset article
- continue on same page
...

spanning chapter titles canbe done with areas or column set spans

Thank you, Hans, for your reply.

I know that with such a complex layout manual adjustment is necessary.
I know about manual balancing. But how to avoid page break after 
columnset closing?

That is the point. How?

> spanning chapter titles canbe done with areas or column set spans

I do not think so, but I can miss something:

column set span:
   a) text flows along the column and can continue bellow the head in 
the first col
   b) problem with making span narrower if it appears in the last col

areas: also a)

Excelent! Thank you very much Hans. Now I understand the balance argument.
Vit

P.S. On the last page (7) text from the bottom of the first col 
continues on the top and it breaks the grid. But this feature I 
(hopefully) will not need.
