[NTG-context] setupregister with realpage?

[Benjamin Buchmuller]

Thank you, Hans! This works, I get all the correct page references!

I didn't know about cont-new.mkxl to temporarily store "hacks". I assume the file is updated with each release? Is there a way to store local hacks, e.g., in texmf-local? I could not find "cont-loc" (maybe it's not a file).

For future reference, this is how I am using the hack:

\def\MyRegisterPageCommand#1{\currentregisterrealpage}

\setupregister[MyRegisterA][pagecommand=\MyRegisterPageCommand]
\setupregister[MyRegisterB][pagecommand=\MyRegisterPageCommand]
