I could not find a pure haskell library to parse EXIF so I wrote one (pretty basic so far): https://github.com/emmanueltouzery/hsexif
Very nice! Why not upload it to hackage to make it easier for others to share and collaborate?
I wrote it with binary-strict. I also considered binary, but I would like the library not to throw an exception if the file that it's given is not a JPEG or is a JPEG without EXIF, but rather return an Either. I didn't manage to do that with binary
Perhaps the function Data.Binary.Get.runGetOrFail is what you are looking for? Or perhaps the incremental strict interface?
And then I realized that binary-strict was last updated in 2010, it seems cereal is recommended for strict binary file parsing nowadays. So, what should I do? Leave it as it is? Port to cereal? Port to binary?
The binary-strict library is no longer maintained, since binary now also provides a strict interface. Both binary and cereal are good choices. Probably porting to binary would be easiest if you've already written it for binary-strict, assuming runGetOrFail or the incremental interface does what you want. Regards, Yitz
