Username string `in:"path=username"`
Visibility string `in:"query=visibility"`
Fork bool `in:"query=fork"`

func ListUserRepos(rw http.ResponseWriter, r *http.Request) {
// Retrieve you data in one line of code!
input := r.Context().Value(httpin.Input).(*ListUserReposInput)

fmt.Printf("input: %#v\n", input)

func init() {
// Register a directive named "path" to retrieve values from `mux.Vars`,
// i.e. decode path variables.
httpin.UseGorillaMux("path", mux.Vars)

func main() {
router := mux.NewRouter()

// Bind input struct with handler.
router.Handle("/users/{username}/repos", alice.New(

r, _ := http.NewRequest("GET", "/users/ggicci/repos?visibility=public&fork=1", nil)

rw := httptest.NewRecorder()
router.ServeHTTP(rw, r)
