Comments are lost when formatting

[leehambley]

We use format-graphql along side the graphql-schema-linter package (via https://pre-commit.com/)

graphql-schema-linter provides the means to disable some of it's lint checks (unused types, camel casing) https://github.com/cjoudrey/graphql-schema-linter#inline-rule-overrides

However, when using it with format-grahpql the comments all disappear.

I would have guessed that because comments aren't necessarily part of the GraphQL spec, that any parser from GraphQL might just eat them, and not provide them as AST nodes, but in fact the spec does define comments:

• https://spec.graphql.org/June2018/#sec-Comments

graphql/graphql-js#2241

Thanks @gajus - I suspected something like this, Rust's serde YAML suffers the same problem, because the underlying YAML parser doesn't preserve comments. (Ruby also had the same problem with the parser tools for the first 20 years it existed, and only recently learned to preserve comments on the AST)

@gajus Is this possible now with ardatan/graphql-tools#1900?
