A "science experiment" repo containing some attempts at improving the macro-writing experience.
So far somewhat unsatisfactory--feels like it addresses real pain points, but in a not-fully-satisfying way,
The macro-transflection subsystem streamlines "transflecting" a macro's argument values across the "boundary" between:
- their use in your own code's source
- their use during macro expansion
In other words, the starting point is a macro invocation like this:
@AddLogging(style: .foo)
func bar(baz: Baz) -> Whatever { }...wherein .foo is a case within some enum LogStyle.
Out of the box, when @AddLogging is expanded, it only has access to syntax: it knows .foo is the syntax of an enumeration case, etc., but that's all it knows--the connection to enum LogStyle is absent. The utilities in the macro-transflaction component exist to streamline "recovering" these actual values while expanding the macro itself.
