Re[2]: [Haskell-cafe] Any generic serializer to String? was: Any working example of using genericserialize?

Hello Max, Wednesday, September 30, 2009, 5:53:37 PM, you wrote: afaik, SYB just provides gshow/gread functions what serialize any Data instance to String

FWIW, writing your own is not hard. I wrote a serializer for GHC using Data in less than 150 (simple) LOC. It produces [Word8], but producing strings instead would be easy. You can check out the code here:

Seems like using withList is wrong or the deserializer is simply buggy.  It certainly doesn't work the way I would expect SExp reading to work.  I also notice from reading the source on hackage that there may not be any tests for this package and it is a 0.1 release.  I'd contact the author, as it seems there is a deficiency in the documentation or a bug in the implementation.

Thanks Jason for trying this. The genericserialize package is probably not finished yet.

What else exists that could be used to serialize in generic way (i. e., anything that is an instance of Data and Typeable) into a string? It does not need to be very efficient as structures to be serialized are not huge (but may be pretty complex), and serialization is a part of an utility not to be used frequently. It only needs to "just work".

One thing I thought of was to serialize to JSON (there is a generic serializer in one of packages although I did not test it other way) which has higher overhead than S-expressions though.

Any other thoughts?

Thanks.
