As I understand it, if you attempt to call an undefined macro the call fails silently, with nothing displaying in the tiddler to alert users. This occurs regardless of the calling method, i.e.,
<<not-a-real-macro>> or <$macrocall $name="not-a-real-macro"/> *Is there a technique for checking whether a macro is defined, and displaying a message in the tiddler if the macro is not defined?* Ideally, the test would not just check for *output* from the macro, since there might be valid circumstances where a macro produces no output. -David -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
