aeson-zippy

A small library for zipper-style traversals of Aeson Values.

This library is heavily inspired by the interface waargonaut provides but functions on top of the existing JSON parsing machinery of aeson. While waargonaut offers a very interesting optimization for decoding JSON (succinct data structures) this optimization limits waargonaut to the x86-64 architecture and some of it's dependencies can be difficult to get working out-of-the-box (eg. in nixpkgs); aeson-zippy is a thin layer over aeson and should work everywhere aeson does.

Objectives

• Small overhead vs. FromJSON instances
• Use subset of transitive dependencies of aeson

TODO

• tests
• benchmarks to determine overhead vs. aeson FromJSON instances
