big vertical distance

big vertical distance

[Wolfgang Werners-Lucchini]

Hallo,

the following was ok with mkII:

% coding: utf-8
\def\B{\vphantom{\bigg)}}
\setupbodyfont[11pt,sans]
\starttext
\startitemize[a,columns,three,joinedup][grid=no,width=8mm,right=)]
\item $\B 5b\cdot (3a+4b-5c)$
\item $\B 3xy\cdot (2x-6y-xy)$
\item $\B (-0{,}5x)\cdot (3y-5x)$
\item $\B (2z-3x+5)\cdot (0{,}5z+x)$
\item $\B 8ac\cdot 3\frac{1}{4}ax$
\item $\B 2\frac{1}{2}ab\cdot 6ax$
\item $\B \frac{2}{3}ax\cdot 1\frac{1}{2}by$
\item $\B 7\frac{1}{2}ay\cdot 1\frac{3}{5}ax$
\item $\B (+4ab)\cdot (-15xy)$
\stopitemize
\stoptext

now with LuaTeX I get very large vertical distances. Much more then 
\bigg(. Why is this? 

Wolfgang

MkIV has a different column mechanism controlled by gridsnapping and 
\bigg is pretty big in that case

Anyhow, there is no grid=no in itemize, at least not now, so you can use:

\setupmixedcolumns
   [itemgroupcolumns]
   [grid=no]

However, we can do this too:

\unprotect

\setupmixedcolumns
   [\s!itemgroupcolumns]
   [\c!grid=\itemgroupparameter\c!grid]

\setupitemgroups
   [\c!grid=\v!tolerant]

\protect

After which we can say grid=no so I'll add that.

Hans
