Code Generation for Enum does not match example

Taking an example from features/sum-types

main.dingo:

package main

enum Payment {
    Cash,
    Card {
        number: string,
        expiry: string,
    },
    Crypto {
        wallet: string,
        currency: string,
    },
}

enum Order {
    Draft {
        items: []Item,
        customer_id: string,
    },
    Pending {
        order_id: string,
        total: float64,
    },
    Paid {
        order_id: string,
        payment: Payment,
        receipt_url: string,
    },
    Cancelled(string),
}

The generated main.go:

package main

// dingo:n:1
type PaymentTag uint8

const (
	PaymentTagCash PaymentTag = iota
)

type Payment struct {
	tag PaymentTag
}

func PaymentCash() Payment {
	return Payment{tag: PaymentTagCash}
}
func (e Payment) IsCash() bool {
	return e.tag == PaymentTagCash
}

// dingo:n:0
type OrderTag uint8

const (
	OrderTagCancelled OrderTag = iota
)

type Order struct {
	tag       OrderTag
	cancelled *string
}
func OrderCancelled(arg0 string) Order {
	return Order{tag: OrderTagCancelled, cancelled: &arg0}
}
func (e Order) IsCancelled() bool {
	return e.tag == OrderTagCancelled
}

Is this expected?

yep sorry for confusing, we had three iterations of generators:

• full ast
• regexp
• post ast

so some examples and some code missmatch becuse the third refactoring in progress

This has been resolved. Enum codegen now correctly generates all variants including multi-field structs:

enum Payment {
    Cash,
    Card { number: string, expiry: string },
    Crypto { wallet: string, currency: string },
}

Generates proper Go interface + struct pattern with NewPaymentCash(), NewPaymentCard(number, expiry), etc. All variants compile and run correctly.

The original report was against a very early version where the codegen was being rewritten. Closing as resolved.
