Re: [Haskell-cafe] Problem on overlapping instances

I agree, but with a slight difference. Since I am so lazy, if Binary fits, like 80% of my requirements, for example this case, only [String] is not OK. I'd like to reuse it with a little modification made by myself, rather than re-write almost the whole of it. But for Data.Binary, I think this problem is simple. Since it cannot be derivinged, making extra function for [String] won't make the further usage of my library complex. On Fri, Jan 7, 2011 at 11:32 AM, Antoine Latter wrote:

Hello,

I only use the 'Binary' class when I don't care about the specifics of the serialization format, only that it be reasonably fast, compact and stable.

When I need to comply with some particular format I use the functions in Data.Binary.Builder and Data.Binary.Get directly. Sometimes I make my own Serialize/Deserialize classes if I think it will be helpful.

But I do look at the source for the instances of the 'Binary' class for inspiration!

Take care, Antoine

Hi,  I am using Data.Binary which defined "instance Binary a => Binary [a]". Now I need to define "instance Binary [String]" to make something special for string list.  How to make it work? I looked into the chapter of overlappinginstances, nothing works. -- 竹密岂妨流水过 山高哪阻野云飞
