columnsets messed up

columnsets messed up

[Henning Hraban Ramm]

Hi,
I’m working at the current CG journal whose layout uses columnsets. They aren’t usable any more. Same in current LMTX and MkIV.

- the first line can start one or more lines lower
- then the same number of lines is printed over each other at the bottom
- it gets worse with footnotes (looks like their space isn’t considered at all)
- if the column set doesn’t start at the top of the page, the second column does


Hraban


\definecolumnset[cgjcolset][n=2]

\starttext

\chapter{This is a chapter about column sets}

\startcolumnset[cgjcolset]

\dorecurse{20}{
\samplefile{sapolsky}\par
}

\stopcolumnset

\stoptext

Personally I'd never use columnsets for anything else than very 
controlled situations because that's what they were made for. Not to be 
mixed with the normal pagebuilder. So, first of all you need to operate 
on the grid (i can probably get rid of some side effects and maigt even 
force that but not now). Then, \chapter itself flushes pages so that 
should be disabled.

Here is a simple example:

\setuplayout[lines=40,grid=yes]

\definecolumnset[cgjcolset][n=2]

\starttext

\definecolumnsetspan
  [chapter]
  [background=color,
   backgroundcolor=red]

\setuphead[chapter][page=no,after=,before=]

\startcolumnset[cgjcolset]

     \startcolumnsetspan[chapter]
         \chapter{This is a chapter about column sets}
     \stopcolumnsetspan

     \dorecurse{20}{
         \samplefile{sapolsky}\par
     }

\stopcolumnset

\stoptext

Thank you, I got it mostly working now.

The CGJ layout doesn’t actually use \chapter but its own convoluted \startArticle. Until last issue it tried to be flexible and setup three different column modes. Now I eliminated the last leftovers of that. I still struggle to understand some pecularities...

What I did wrong:
* \setuplayout[grid=yes] is important
* you can’t start a columnsetspan before the columnset

leter this year i will into the several column mechanisms (maybe also 
some mechanism to warn for mixed usage or use of features that interfere 
.. doing columns is hairy in tex)

Even curioser:

If there isn’t a \page after \stopcolumnset, the second-to-last section (subject) disappears and the last one is typeset completely.

(Later:)
Ok, found it:

\def\stopArticle{%
  \par\signArticle
  \doif{\getvariable{CG-Journal}{NOFColumns}}{>1}
  {\stopcolumnset}
  \page
}

--> \stopcolumnset is never executed, since \doif can’t handle ">1". – Did it ever or is this a regression?
