This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.

This parser consumes lazy ByteStrings to produce JSON in a simple, efficient format backed with strict ByteStrings, Rationals and ByteString tries. See the schema generation tools and the command line JSON schema generator (in the examples subdir) for an example of how to use the parsing tools.

Have you considered aeson (http://hackage.haskell.org/package/aeson), a newer, extensively benchmarked JSON parsing library?
