conjson - (conventional, consistent, conformative) JSON
A simple, functional, no-tags-required mechanism to handle and transform JSON representations of values, consistently.
This project is currently in "pre-release". While the code is heavily tested, the API may change. Vendor or "lock" this dependency if you plan on using it.
This project was originally born from a 3+ year old (at the time of creation) "Gist".
Both that Gist, and eventually this larger project, were inspired by a desire to more easily work with APIs that accepted/returned JSON that had "snake_case"-style object keys.
Basically, I wanted a way to Marshal and Unmarshal Go structures without having to add "tags" to each and every field of each and every structure. That Gist solved that problem for me, and now this library can do the same but with more power and flexibility.

}
