Re: [NTG-context] callback.register

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'?
