[NTG-context] \box0 to Lua
Hello,
(my apologies if this message is duplicated - our mail server was out-of-order
some time)
how to call \box0 and \hbox to3cm{abc} by Lua?
\startluacode
context[[\box0]] % OK but a nicer way preferred, so keep on trying -
context.box(0) % Error
context.box{0} % Error
context.box0 % Error
context.hbox({to = cm}, abc) % Error
\stopluacode
TIA.
Best regards,
Lukas

sorry for impoliteness - last two messages should't have been addressed to the
forum, but only to me and Jaroslav - thus in Czech.
The question still lasts...

The first argument is the head of a node list, the second can be
the width in sp (or “spread”). See Patrick’s excellent tutorial:
http://wiki.luatex.org/index.php/TeX_without_TeX
to get started with node fun.
(The \boxn registers are accessible as tex.box, see page 112 in
the luatex manual.)
