Generate OpenApi 3.1 compatible Enums?

[JohnGalt1717]

Hi, is it possible to generate enaums like this: https://stackoverflow.com/questions/66465888/how-to-define-enum-mapping-in-openapi ?

I can't find any documentation on how to enable it, but I need 3.1 compatibility with the oneOf syntax.

You can implement your own ISchemaProcessor and transform all enum schemas to OAI 3.1 enum schemas

OK, thanks.

Is there any plans to add this natively?

PS for anyone that needs it, here's quick and dirty standards compliant enum Schema Processor.

public sealed class FixNSwagEnumsProcessor : ISchemaProcessor {
	public void Process(SchemaProcessorContext context) {
		if (!context.ContextualType.Type.IsEnum)
			return;
		
		foreach(var item in context.Schema.EnumerationNames.Index()) {
			var enumValue = context.Schema.Enumeration.ElementAt(item.index);
			var enumSchema = new JsonSchema
			{
				ExtensionData = new Dictionary<string, object?>
				{
					{ "const", enumValue },
					{ "title", item.item }
				}
			};

			context.Schema.OneOf.Add(enumSchema);			
		}
	}
}
