Depends on #3115

Implements graphql/graphql-spec#794

Adds:

  • DOT punctuator in lexer
  • Improvements to lexer errors around misuse of .
  • Minor improvement to parser core which simplified this addition
  • SchemaCoordinate node and isSchemaCoodinate() predicate
  • Support in print() and visit()
  • Added function parseSchemaCoordinate() since it is a parser entry point.
  • Added function resolveSchemaCoordinate() and resolveASTSchemeCoordinate() which implement the semantics (name mirrored from buildASTSchema) as well as the return type GraphQLSchemaElement

Amazing!

This is way beyond what I was hacking with. Hadn't even considered reusing the existing parser. (I was fiddling around with regexes...)

Thanks for putting this together - this makes a lot of sense.

Great feedback - I think I've resolved both:

  • Replaced fieldName with memberName in the AST to ensure it's generalized between fields, input fields, and enum values. Those are all specific instances of the general pattern of "members of a set", which is pretty common terminology for this generalized dot access pattern.
  • Took both of your great suggestions for wrapping the return type of resolveSchemaCoordinate - the ResolvedSchemaElement type is now a union of wrappers. This had the added benefits of disambiguating between "field argument" and "directive argument" and including the coordinate context in the return value

Implements graphql/graphql-spec#794

Adds:

* DOT punctuator in lexer
* Improvements to lexer errors around misuse of `.`
* Minor improvement to parser core which simplified this addition
* `SchemaCoordinate` node and `isSchemaCoodinate()` predicate
* Support in `print()` and `visit()`
* Added function `parseSchemaCoordinate()` since it is a parser entry point.
* Added function `resolveSchemaCoordinate()` and `resolveASTSchemaCoordinate()` which implement the semantics (name mirrored from `buildASTSchema`) as well as the return type `ResolvedSchemaElement`

[#3049 rebased on
main](#3049).

This is the last rebased PR from the original PR stack concluding with
#3049.

Update: #3044 and #3145 have been separated from this stack.

Changes from original PR:
1. `astFromValue()` is deprecated instead of being removed.

@leebyron comments from #3049, the original PR:
> Implements
[graphql/graphql-spec#793](graphql/graphql-spec#793)
> 
> * BREAKING: Changes default values from being represented as an
assumed-coerced "internal input value" to a pre-coerced "external input
value" (See chart below).
> This allows programmatically provided default values to be represented
in the same domain as values sent to the service via variable values,
and allows it to have well defined methods for both transforming into a
printed GraphQL literal string for introspection / schema printing (via
`valueToLiteral()`) or coercing into an "internal input value" for use
at runtime (via `coerceInputValue()`)
> To support this change in value type, this PR adds two related
behavioral changes:
>   
> * Adds coercion of default values from external to internal at runtime
(within `coerceInputValue()`)
> * Removes `astFromValue()`, replacing it with `valueToLiteral()` for
use in introspection and schema printing. `astFromValue()` performed
unsafe "uncoercion" to convert an "Internal input value" directly to a
"GraphQL Literal AST", where `valueToLiteral()` performs a well defined
transform from "External input value" to "GraphQL Literal AST".
> * Adds validation of default values during schema validation.
> Since assumed-coerced "internal" values may not pass "external"
validation (for example, Enum values), an additional validation error
has been included which attempts to detect this case and report a
strategy for resolution.

…QLEnumValue (#4288)

this extracts logic from #3044 and #3145 (later rebased as #3807 and
#3808) to implement more informative error messages without implementing
[the full schema coordinate
RFC](graphql/graphql-spec#794)

This is a BREAKING CHANGE because these schema elements are now longer
plain objects and function differently in various scenarios, for example
with `String(<schemaElement>` `JSON.stringifu(<schemaElement>` and
`.toString()` and `.toJSON()`
