My example looks now
\starttext
\startluacode
function MyPreLB(head,gc)
texio.write("\n")
for n in node.traverse(head) do
if node.type(n.id) == "glyph" then
texio.write(string.char(n.char))
elseif node.type(n.id) == "glue" then
texio.write(' ')
end
end
texio.write("\n")
return head
end
tasks.appendaction("processors","before","MyPreLB")
\stopluacode
Dies ist ein Test.
\stoptext
Is it correct to return 'head'?
Wolfgang
