issues with kitgen

[OmegaRogue]

when trying kitgen on one of the examples, it works fine, but when trying to run it on my own service, it panics:

C:\Users\OmegaRogue\go\src\go-kit-todolist\todo-service>kitgen service.go
panic: interface conversion: ast.Node is *ast.SelectorExpr, not *ast.Ident

i can't really find any differences between my code and the example code:

// my code
package todosvc

import "context"

type Service interface {
	Hello(ctx context.Context) (string, error)
	ListAll(ctx context.Context) ([]List, error)
	List(ctx context.Context, user string) (List, error)
}

type List struct {
	User  string              `json:"name"`
	Tasks map[string][]string `json:"tasks,omitempty"`
}

// example code
package profilesvc

import "context"

type Service interface {
	PostProfile(ctx context.Context, p Profile) error
	GetProfile(ctx context.Context, id string) (Profile, error)
	PutProfile(ctx context.Context, id string, p Profile) error
	PatchProfile(ctx context.Context, id string, p Profile) error
	DeleteProfile(ctx context.Context, id string) error
	GetAddresses(ctx context.Context, profileID string) ([]Address, error)
	GetAddress(ctx context.Context, profileID string, addressID string) (Address, error)
	PostAddress(ctx context.Context, profileID string, a Address) error
	DeleteAddress(ctx context.Context, profileID string, addressID string) error
}

type Profile struct {
	ID        string    `json:"id"`
	Name      string    `json:"name,omitempty"`
	Addresses []Address `json:"addresses,omitempty"`
}

type Address struct {
	ID       string `json:"id"`
	Location string `json:"location,omitempty"`
}

I think kitgen has bit-rotted beyond usefulness and I should probably remove it.

[basvanbeek]

@peterbourgon maybe move it to go-kit/kitgen-archived and archive?

[itapai]

is there any other generators we can use?
really like go-kit, but the code duplication/repetitiveness is really too much

[RussellLuo]

Sorry for disturbing you guys!

For those (may be @itapai) who want to try some other alternative generator, I have developed a toolkit named kok, which only supports HTTP transport now.
