requires passing in of "user" parameter, example: `go run main.go -user=davidobrien1985`

main.go

package main

import (
	"encoding/json"
	"flag"
	"fmt"
	"io/ioutil"
	"net/http"
)

var (
	userPtr = flag.String("user", "", "This is the user name whose repos you like to scan. The URL looks like https://github.com/<user>.")
)

type Repos struct {
	Name     string `json:"name"`
	FullName string `json:"full_name"`
}

func main() {
	flag.Parse()

	baseURL := "https://api.github.com"

	getRepoNames(*userPtr, baseURL)
}

func getRepoNames(username string, url string) {
	repoURL := url + "/users/" + username + "/repos"
	fmt.Print(repoURL)
	res, err := http.Get(repoURL)

	if err != nil {
		panic(err)
	}

	defer res.Body.Close()

	body, err := ioutil.ReadAll(res.Body)

	if err != nil {
		panic(err)
	}

	// fmt.Print(string(body))
	var u []Repos

	json.Unmarshal(body, &u)

	fmt.Println(u)
