Hello,
The following code
\setuplabeltext[test=] test is \doifemptyelse{\labeltext{test}}{empty}{not empty}
doesn't work as intended for the reasons that I approximately understand (not exactly, but I understand that there might be a lot of weird stuff returned when I ask for labeltext). However I have no idea how to check if text is empty or not.
As an exception :) :) :), MKIV hints should be highly appreciated and enough for this particular application.
an empty test is always somewhat special as there can be an unexpandable macro inside that eventually expands to nothing
you can try \doiftextelse instead
Thank you very much. This works fine. This should probably be added to http://wiki.contextgarden.net/System_Macros/Branches_and_Decisions at least (possibly to reference next to labels as well), but I'm not sure how to describe it. Mojca
