Multiple types

First let's set up a golang module

module github.com/gen/project

go 1.24

using priorities to config type which has different configuration

packages {
  ["github.com/gen/project"] {
    priorities {
      [0] {
        types { "Status" }
        line_comment = true
      }
    }

    types { "Pill" }
  }
}

source code

// file: enum.go

package enum

type Pill int

const (
	Placebo Pill = iota
	Aspirin
	Ibuprofen
	Paracetamol
	Acetaminophen = Paracetamol
)

type Status int

const (
	StatusInactive Status = iota // inactive
	StatusActive                 // active
)

expected generated code

// golden-file: gen_stringer.go
// Code generated by go-stringer-gen - dev. DO NOT EDIT.

package enum

import "strconv"

// Unnamed variable used to ensure `import "strconv"` is generated, as it is required below.
var _ = strconv.FormatInt(0, 10)

func _() {
	// An "invalid array index" compiler error signifies that the constant values have changed.
	// Re-run the stringer command to generate them again.
	var x [1]struct{}
	_ = x[StatusInactive-0]
	_ = x[StatusActive-1]
}

const _Status_name = "inactiveactive"

var _Status_index = [...]uint8{0, 8, 14}

func (i Status) String() string {
	idx := int(i) - 0
	if i < 0 || idx >= len(_Status_index)-1 {
		return "Status(" + strconv.FormatInt(int64(i), 10) + ")"
	}
	return _Status_name[_Status_index[idx]:_Status_index[idx+1]]
}
