Sqldelight: Support Kotlin Gradle DSL

[LouisCAD]

This: fun methodMissing(name: String, args: Any): Any is not practical to use with Kotlin Gradle DSL.
This is also not typesafe.

For anyone wanting to use the SqlDelight Gradle plugin from Gradle Kotlin DSL until this issue is solved, here's a small example that should work:

sqldelight {
    methodMissing("MyDatabase", arrayOf(closureOf<SqlDelightDatabase> {
        packageName = "com.example.db"
        sourceFolders = listOf("db")
        schemaOutputDirectory = file("build/dbs")
        dependency project(":OtherProject")
    }))
}

Does anyone have a build.gradle.kts example? I can't get the sqldelight stanza to even be accepted although the plugin appears to have been loaded.

@nwillc My example shown above should work. Note that you need to have this enableFeaturePreview("GRADLE_METADATA") in your settings.gradle.kts for it to work as it's still need for Kotlin multiplatform for now.

I think adding an extension method would suffice for now. How does this look?

fun SqlDelightExtension.createDataBase(dataBaseName: String, configuration: SqlDelightDatabase.() -> Unit) {
    methodMissing(dataBaseName, arrayOf(closureOf(configuration)))
}

sqldelight {
    createDataBase("Database") {
        packageName = "com.example.pacakge"
    }
}
