A port of the parser from graphql-js into golang

gqlparser

This is a parser for graphql, written to mirror the graphql-js reference implementation as closely while remaining idiomatic and easy to use.

spec target: June 2018 (Schema definition language, block strings as descriptions, error paths & extension)

This parser is used by gqlgen, and it should be reasonably stable.

Guiding principles:

• maintainability: It should be easy to stay up to date with the spec
• well tested: It shouldn't need a graphql server to validate itself. Changes to this repo should be self contained.
• server agnostic: It should be usable by any of the graphql server implementations, and any graphql client tooling.
• idiomatic & stable api: It should follow go best practices, especially around forwards compatibility.
• fast: Where it doesn't impact on the above it should be fast. Avoid unnecessary allocs in hot paths.
• close to reference: Where it doesn't impact on the above, it should stay close to the graphql/graphql-js reference implementation.
