Dear list
With LMTX the Following MWE does not seem find attribute value (it does with luatex 1.10)
\defineattribute[MarginNode][public]
\newbox\MyBox
\startluacode
local nuts = nodes.nuts
local margin_node_attr = attributes.public('MarginNode')
function test_attribute(box_id)
local box = nuts.takebox(box_id)
local margin_node = nuts.getattr(box, margin_node_attr)
context('Expected 555=' .. (margin_node or '(nil)'))
end
\stopluacode
\starttext
Test.
\the\MarginNodeattribute
\setbox\MyBox\hbox attr\the\MarginNodeattribute=555{Test}
\ctxlua{test_attribute(\the\MyBox)}
\stoptext
Thanks
