DSL. In fact a guy at the Clojure NYC meetup did this exact thing (for financial data, in clojure) to generate all the Java APIs needed to consume/write the data files. Groovy or JRuby might be a better choice depending on how averse you are to toenail-based languages, but this is precisely the kind of thing DSLs are good for, and it's a lot easier to remember a human-readable DSL than the scanf spec, and it'd be easier to add domain-specific data types.
