Na to budeš potřebovat node.hpack() (luatexref-t.pdf, s. 95).
···8<···································································
\starttext
foo
\startluacode
local newnode = node.new(node.id"glyph")
newnode.char = unicode.utf8.byte"x"
newnode.font = font.current() -- won’t work before \starttext
newnode.lang = tex.language
--- second arg to node.hpack is width <int>
local hbox = node.hpack(newnode, 2*newnode.width)
node.write(hbox)
\stopluacode
bar
\stoptext
···8<···································································
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 \box<n> registers are accessible as tex.box, see page 112 in
the luatex manual.)
