In the following example (which doesn't give a valid pdf, it is only for demo) the logging has changed between texlive 2018 and 2019: In texlive 2018 the log said: ...\pdfliteral page"/Artifact /BMC" In texlive 2019 I now get ...\pdfliteral page This sadly means that my testsuites are no longer really meaningful. Is there a way to get the old behaviour back? Or to somehow add the content of the "" to the log? \tracingoutput 1 \showboxbreadth \maxdimen \showboxdepth \maxdimen \tracingonline 1 \setbox0\hbox{a} \directlua{ for n in node.traverse(tex.box[0].list) do local bdcnode = node.new("whatsit","pdf_literal") bdcnode.data = "/Artifact /BMC" bdcnode.mode=1 tex.box[0].list = node.insert_before(tex.box[0].list,n,bdcnode) end } \box0 \bye -- Ulrike Fischer http://www.troubleshooting-tex.de/
