Preliminary version of validation #14

Closed aew closed 8 years ago

aew commented 8 years ago

Very preliminary and partial implementation of validation, mainly for early feedback:

Depends on clojure.spec, so requires clojure 1.9.0-alpha2
Use global named specs that match the nested structure of the tree
Use zippers and zip-visit to implement the visitor pattern (mirrors structure of graphql-js reference implementation)
Make handling lists of scalars more consistent

There are a number of TODO's in the code.

Thanks for taking on this. I was thinking about using clojure.spec for a while.

Although clojure.spec was introduced in Clojure 1.9, I have heard Clojure 1.9 alpha versions are getting more early adopters. For any one using Clojure 1.8, they can use https://github.com/tonsky/clojure-future-spec with Clojure 1.8.
