Honestly, judging from the responses in this thread, it would seem there may be a hole in Racket’s toolbox. Nothing I’ve seen so far is particularly stellar, especially since this is a problem that does not seem like it should be hard.
It may be overkill for this use case, but I would probably use the parsack package, since I think its interface is pretty intuitive. However, it would be nice to have some sort of inverse to printf that parses values given a template string. Racket has a very good set of tools for formatting text, but it seems that doing the inverse is much harder, which seems to be against Racket’s “batteries included” philosophy. Would anyone object to a scanf-like function in Racket itself? The obvious point of difficulty is how to handle errors, given that parsing can fail but printing cannot. Should it throw an exception, or should it return #f? I’m not sure there is great precedent set here, though throwing seems to be the Racket way in other places. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
