...

there are two user hooks:

tasks.appendaction("processors","before","modules.mine.whatever_a") tasks.appendaction("processors","after","modules.mine.whatever_b") -----------------------------------------

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'?

Maybe 'return head, true', because I found a few functions in the beta do so. Such as 'scripts.preprocess'. -- Best regards, Li Yanrui (李延瑞)
