Try \doiftext which typesets the material and checks its width. > The problem I'm having is, when fed a blank macro, `\define\needsoven{}` it > thinks there is content, so it displays the "Materials" heading, but an empty > list.

So I need `\define\needsoven{}` to be regarded as nothing. \define\needsoven makes \needsoven non-expandable. You either need \defineexpandable\needsoven or use \doiftext Aditya ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://www.ntg.nl/mailman/listinfo/ntg-context webpage : https://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : https://contextgarden.net ___________________________________________________________________________________
