Example

Input

package userservice

import (
    "context"
    "errors"
)

// User represents a system user
type User struct {
    ID    string `json:"id"`
    Name  string `json:"name"`
    Email string `json:"email"`
}

// UserService handles user operations
type UserService interface {
    GetUser(ctx context.Context, id string) (*User, error)
    CreateUser(ctx context.Context, user *User) error
}

// NotFoundError is returned when a user is not found
var NotFoundError = errors.New("user not found")

// GetUser retrieves a user by ID
func (s *Service) GetUser(ctx context.Context, id string) (*User, error) {
    // implementation...
    return nil, NotFoundError
}

Output (Brf.it)

// userservice/user.go
package userservice

import ( "context"; "errors" )

type User struct { ID string; Name string; Email string }
type UserService interface { GetUser(ctx context.Context, id string) (*User, error); CreateUser(ctx context.Context, user *User) error }
var NotFoundError = errors.New("user not found")
func (s *Service) GetUser(ctx context.Context, id string) (*User, error)
