Current enum value isn't present on GraphQLEnumType_values_value scope

[benjie]

const makeDeprecateEnumsPlugin = (enumTypeName: string, enumValues: string[], deprecationReason: string): GraphileConfig.Plugin => ({
  name: `DeprecateEnumsPlugin_${enumTypeName}_${enumValues.join("_")}`,
  value: "0.0.0",

  schema: {
    hooks: {
      GraphQLEnumType_values_value(value, build, context) {
        if (context.Self.name !== enumTypeName) return value;
        if (!enumValues.includes(context.scope.OH_NO_THIS_DOESNT_EXIST_YET)) return value;
        return {
          ...value,
          deprecationReason,
        }
      }
    }
  }
});

Should be equivalent to the fieldName on the GraphQLObjectType_fields_field scope. enumValueName?

Turns out Self also doesn't exist; and both are for the reason outlined in the graphql-js issue above.

On hold due to #2142

Something like this should work:

const makeDeprecateEnumsPlugin = (enumTypeName: string, enumValues: string[], deprecationReason: string): GraphileConfig.Plugin => ({
  name: `DeprecateEnumsPlugin_${enumTypeName}_${enumValues.join("_")}`,
  value: "0.0.0",

  schema: {
    hooks: {
      GraphQLEnumType_values_value(value, build, context) {
        if (context.Self.name !== enumTypeName) return value;
        if (!enumValues.includes(context.scope.valueName)) return value;
        return {
          ...value,
          deprecationReason,
        }
      }
    }
  }
});
