Hello mostly Czech ConTeXters,

I have noticed in the modules.pdf that there are some Czech slot empty 
in the lang-sla.tex. Most of them are filled up now. All changes are 
marked by 'new' comment. Main changes:

- redefinition of 'dashes' (pomlcek)
    \c!leftsentence=\thickglue--\thickglue\penalty-20,
    \c!rightsentence=\thickglue--\thickglue\penalty-20,
    \c!leftsubsentence=~---~\penalty-20,
    \c!rightsubsentence=~---~\penalty-20,
   (intends were: endash size preferable, short stretchable/shrinkable
    spaces around, line break possible after dash but not before; it
    conforms Czech typographical rules)

It needs some new definitions to core-spa.tex (Hans ??):
   \unexpanded\def\textormathglue#1#2#3{%
     {\dimen0=#1\hspaceamount\empty{#3}%
      \skip0=0pt plus.5\dimen0 minus.3\dimen0
      \ifmmode\mskip#1#2%
      \else\kern#1\hspaceamount\empty{#3}\hskip\skip0\fi\relax}%
   }
   \def\thinglue    {\textormathglue+\thinmuskip 1}
   \def\medglue     {\textormathglue+\medmuskip  2}
   \def\thickglue   {\textormathglue+\thickmuskip3}

- definition of day names

- most of empty slot added (Zkratky, Sekce, Subsekce, viz, ...)

The file is attached.

Suggestions are welcomed.

Vit

this boils down to:

\unexpanded\def\textormathglue#1#2#3%
  {\begingroup
   \scratchdimen=#1\hspaceamount\empty{#3}%
   \scratchskip=\zeropoint
      \!!plus.5\scratchdimen
      \!!minus.3\scratchdimen\relax
   \ifmmode
     \mskip#1#2%
   \else
     \kern\scratchdimen
     \hskip\scratchskip
   \fi
   \endgroup}

\def\thinglue {\textormathglue+\thinmuskip 1}
\def\medglue  {\textormathglue+\medmuskip  2}
\def\thickglue{\textormathglue+\thickmuskip3}

why the kern followed by the skip? why not just 

\unexpanded\def\textormathglue#1#2#3%
  {\ifmmode
     \mskip#1#2\relax
   \else  
     \begingroup
     \scratchdimen#1\hspaceamount\empty{#3}%
     \scratchskip
       \scratchdimen  
       \!!plus .5\scratchdimen
       \!!minus.3\scratchdimen
     \hskip\scratchskip
     \endgroup
   \fi}

Yes, that is better.

I was not sure if original kern has not have some secret reason, so I 
preserved as much \textormathspace as possible.

No comments was done for cont-sla.tex, so I would ask you Hans to 
incorporate it to distro. Clean file in attch.

Thanks
Vit

P.S. I had played with sorting but was not successful with uppercase 
accented letters. In texexecnew I noticed there are definition only for 
small letters, so uppercase should be defined by user. But how to do it 
for accented letters I do not know (without brief explanation of 
\exportsortrule, \exportsortshortcut, \exportsortreduction, 
\exportsortdivision there are too much variations - in a way of applied 
order, encoding expression, intended behaviour, not implemented 
features, bugs - and I am not able to solve it im my time possibilities).
