columnset layout distortion

columnset layout distortion

[Vit Zyka]

Hallo,

I am working on our 40-anniversary scout group bulletin with a complex 
layout (twocolumn, footnotes, photos, pictures, flowing text in margin). 
I noticed weird behaviour. It is expressed by vertical shift of columns, 
please see the page 2 of
   http://typokvitek.com/tmp/layoutdistort.pdf
   source: http://typokvitek.com/tmp/layoutdistort.tex

It seems that the problem is caused by switch to \ss font family 
continueing to a place of the page break. Any explanation/suggestion?

Thanks
vit

the linedistance is expressed in ex, and ss has a different ex height

you may try to set the interlinespace to e.g. 14.4pt (or 1.2\bodyfontsize) or so

interesting 'bug/feature' btw, i need to think this over

I seee. Thank you Hans for a very quick response. My response (in case 
of sorting) is much much slower. I have only installed ruby and run your 
example with newtexexec.rb. It runs smoothly (with exception of 
generating format every run newtexexec.rb but - my guess, no time to 
check - it is due to ignoring engines in my texmf.cnf). But I will need 
sorting for name index in this project, so I will have to solve it 
sooner or later.

i made an \restoreinterlinespace mechanism so that you can do the following:

\setuplayout[height=middle,width=middle,grid=yes]

\starttext
   \startcolumnset
     \dorecurse{10}
       {\input thuan \endgraf
        \bgroup
        \ss\restoreinterlinespace
        \dorecurse{3}{\input hawking \endgraf}
        \egroup
        \input bryson \endgraf}
   \stopcolumnset
\stoptext

(tricky stuff)

columnset balancing, footnoterule in columnset, Re: columnset layout distortion

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
------------------------------------------------
