no problem ... maybe we should have a wiki page for 'use this instead of
that'
as you're playing with it ... there is a lot we haven't yet introduced
but we will do that stepwise .. here's one
inline formulas like $(x + a + 2)$ will break across lines but
traditionally \left( .. \right) doesn't which is why these \bigg things
are there : manual solution for breaking inline math
however, in lmtx these do break across lines but there are of course
still cases where the penalties injected will discourage it; there is
agranular penalty system in place but current it is configured as
traditional tex
now, when a formula doesn't break and is somehow wrapped it doesn't play
that well with linebreaks but you can cheat: formulas can becoem liek
glue where the inter atom stretch and shrink can play a more prominent
role ... here's a test:
% turning small inline formulas into leaders to that we don't get overflows
% or excessive spacing
\continuewhenlmtxmode
\startbuffer[threshold-none]
\setupbodyfont[modern]
\setuppapersize[A5]
\setuplayout[tight]
\setupmathematics[threshold=none]
\dorecurse {950} {
test $\darkblue \showboxes x + #1 $
test $\darkred \showboxes x + #1 + z$
}
\stopbuffer
\startbuffer[threshold-small]
\setupbodyfont[modern]

\setuplayout[tight]
\setupmathematics[threshold=small]
\dorecurse {950} {
test $\darkblue \showboxes x + #1 $
test $\darkred \showboxes x + #1 + z$
}

\setuppapersize[A5]

\setupmathematics[threshold=medium]
\dorecurse {950} {

test $\darkred \showboxes x + #1 + z$
}
\stopbuffer
\starttext
\dorecurse {10} {
\startcombination[2*2]
{\hbox to .45\textwidth{\typesetbuffer[threshold-none]
[frame=on,width=.45\textwidth,page=#1]\hss}} {\type {threshold=none}}
{\hbox to .45\textwidth{\typesetbuffer[threshold-small]
[frame=on,width=.45\textwidth,page=#1]\hss}} {\type {threshold=small}}
{\hbox to
.45\textwidth{\typesetbuffer[threshold-medium][frame=on,width=.45\textwidth,page=#1]\hss}}
{\type {threshold=medium}}
{\hbox to .45\textwidth{\typesetbuffer[threshold-big]
[frame=on,width=.45\textwidth,page=#1]\hss}} {\type {threshold=big}}
\stopcombination
}
\stoptext
There is also a system like widows and orphans in the sense that one can
set forward and backward penalties, as in:
\setuplayout[width=11cm]
\startbuffer
\dorecurse {50} {
test $\darkblue a + #1 + b > 2$ %
test $\darkred a + b + #1 + c + d > 2$ %
test $\darkgreen a + b + c + #1 + d + e + f > 2$ %
}
\stopbuffer
\setuptolerance[verytolerant,stretch]
\starttext
\start
\mathforwardpenalties 0
\mathbackwardpenalties 0
\getbuffer
\par
\stop
\page
\start
\mathforwardpenalties 2 -200 -100
\mathbackwardpenalties 2 -100 -50
\getbuffer
\par
\stop
\page
\start
\mathforwardpenalties 2 200 100
\mathbackwardpenalties 2 100 50
\getbuffer
\par
\stop
\page
\stoptext
but we currently don't have a high level interface for that; it will be
part of the more general math penalties setup.
These are just a few of the things to play with.
