Alternatively, if there is a way to change the generated scalar name created during apollo code gen that’d also work

[bod]

Hi! In Apollo Kotlin there's a @targetName directive you can use to instruct the codegen to use a different name. It was introduced here.

Example usage here

[Paddy O'Brien]

perfect thanks!

[Paddy O'Brien]

So I just gave this a try
• I created an extra.graphqls file
• It lives next to my schema.json
• Its contents are

# Remap names that will result in collisions, in particular when exported to Swift
extend scalar URL @targetName(name: "URL_")

• Definition in the schema is

"type": {
  "kind": "NON_NULL",
  "name": null,
  "ofType": {
    "kind": "SCALAR",
    "name": "URL",
    "ofType": null
  }
},

• I cleared the gradle cache
• I manually deleted the generated apollo sources
• in kotlin im still getting

public class URL {
  public companion object {
    public val type: CustomScalarType = CustomScalarType("URL", "kotlin.String")
  }
}

• in Swift im still getting

__attribute__((objc_subclassing_restricted))
__attribute__((swift_name("URL")))
@interface NativeSyncURL : NativeSyncBase
- (instancetype)init __attribute__((swift_name("init()"))) __attribute__((objc_designated_initializer));
+ (instancetype)new __attribute__((availability(swift, unavailable, message="use object initializers instead")));
@property (class, readonly, getter=companion) NativeSyncURLCompanion *companion __attribute__((swift_name("companion")));
@end;

• build.gradle

service("admin") {
  useVersion2Compat("com.admin")
  schemaFile = file("src/commonMain/graphql/admin/schema.json")
  sourceFolder.set("admin")
  mapScalarToKotlinString("URL")
}

Apollogies for the info dump, saw in the Github issue you were waiting on info so im trying to be complete

[Paddy O'Brien]

im not seeing any errors in the log

[Paddy O'Brien]

This is in 3.5

[bod]

Hmm what you did looks good - wondering why it doesn't work. The generated Kotlin file should be named URL_

[Paddy O'Brien]

Its still named URL

[Paddy O'Brien]

Is it possibly related to useVersion2Compat or the fact that we use schema.json and not schema.graphqls as mentioned in the issue?

[bod]

It shouldn't

(by the way, you can convert your schema to .graphqls, it is a bit nicer to work with! ./gradlew convertApolloSchema --from=src/main/graphql/schema.json --to=src/main/graphql/schema.graphqls )

[bod]

oh I know: it's because of schemaFile = , in that case the extra.graphqls is not automatically taken into account. You need to include it manually:

schemaFiles.setFrom(setOf(file("src/main/graphql/schema.json"), file(file("src/main/graphql/extra.graphqls"))))

gradle sync fails when I use that

10:11 a.m.	Gradle sync failed: No signature of method: build_a7r62ca1lbwotzkp5jpoglq3a.apollo() is applicable for argument types: (build_a7r62ca1lbwotzkp5jpoglq3a$_run_closure2) values: [build_a7r62ca1lbwotzkp5jpoglq3a$_run_closure2@19625293]

[bod]

wow, that stacktrace 😅

maybe it's the kts syntax that Groovy doesn't like? Does setOf exist in Groovy?

[Paddy O'Brien]

I should note that you have 3 file( in your example, I assumed the file(file( was a typo

[bod]

woops! yes sorry about that

[Paddy O'Brien]

k, I had removed the duplicate which had that error

[Paddy O'Brien]

it does have set

[Paddy O'Brien]

or does it 😅

[bod]

would this work?

schemaFiles.setFrom(files("src/main/graphql/schema.json", "src/main/graphql/extra.graphqls"))

[Paddy O'Brien]

That’s generated the right type. Thanks for working through it with me

[bod]

Great! 🎉
