Hi all,
[[ Hraban is not the only one with yet more questions... ]]
(While trying to come to grips with the Zen of \testpage, I've been diverted
into contemplating various spacing parameters...)
With this small example document:
%%%%
\setupbodyfont[10pt]
\starttext
The baselineskip is \the\baselineskip
The smallskipamount is \the\smallskipamount
\stoptext
%%%
I get the output:
The baselineskip is 12.06137pt
The smallskipamount is 2.2615pt plus 0.75383pt minus 0.75383pt
In .../tex/texmf-context/tex/context/base/mkxl/syst-ini.mkxl I see
\newgluespec \smallskipamount \smallskipamount = 3pt plus 1pt minus 1pt
so initially, I might have expected \smallskipamount to be
3pt plus 1pt minus 1pt
but I also see in .../tex/texmf-context/tex/context/base/mkxl/spac-def.mkxl
\synchronizeskipamounts
is added to \everybodyfont, and in .../spac-ver.mkxl we have
\permanent\protected\def\synchronizeskipamounts
{\bigskipamount
\skipfactor\baselineskip
\s!plus\skipgluefactor\baselineskip
\s!minus\skipgluefactor\baselineskip
\relax
\medskipamount \bigskipamount \divideby\medskipamount \plustwo
\smallskipamount\bigskipamount \divideby\smallskipamount\plusfour}
and so I am a bit confused.
(1) Why is \smallskipamount set to the same as plain TeX in syst-init.mkxl
when it is just going to be reset to be 1/4 of the *adjusted*
\baselineskip ?
(2) Why is \skipfactor 0.75?
And when I changed the body font size to 10 pt (just to do some comparisons
with plain TeX), I boldly assumed \baselineskip might be 12pt. I looked at
the code for a while, but got lost.
(3) Why is \baselineskip set to this curious amount, rather than 12pt?
Thanks to anyone who can enlighten me.
Jim
