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.box"0" % Error

context.hbox({to = "cm"}, "abc") % Error \stopluacode ----

TIA.

Best regards,

Lukas

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.)

... Thanks Philipp and Hans for hints, I'll keep on trying. BTW: I'd never guess how Czech will become popular ;) Best regards, Lukas

\starttext \startluacode context(typesetters.hpack("Na to budeš potřebovat 'typesetters.hpack'")) \stopluacode \stoptext
