Iterate over json array in Go to extract values -

i have following in json array (conf.json file).

{   "repos": [       "a",       "b",       "c"   ] } 

i attempting read json , iterate on stuck. new go (and programming) having hard time understanding happening here.

import (     "encoding/json"     "fmt"     "os" )  type configuration struct {     repos []string }  func read_config() {     file, _ := os.open("conf.json")     decoder := json.newdecoder(file)     configuration := configuration{}     err := decoder.decode(&configuration)     if err != nil {         fmt.println("error:", err)     }      fmt.println(configuration.repos) } 

so far far have been able get. print out values okay, [a, b, c].

what able iterate on array , split out each value individually have not had luck @ doing this. taking wrong approach this? there better way this?

you mean this:

for _, repo := range configuration.repos {     fmt.println(repo) } 

note code in example should not work json have given. there no mapping between value , repos. either have posted incorrect json or omitted tag on configuration struct map correctly.
