JSON を treeコマンド風に表示する gem を作った

Ruby

Posted at 2017-10-09

JSON を tree コマンドっぽく表示出来ます。

{
  "id": 1,
  "name": "Leanne Graham",
  "username": "Bret",
  "email": "Sincere@april.biz",
  "address": {
    "street": "Kulas Light",
    "suite": "Apt. 556",
    "city": "Gwenborough",
    "zipcode": "92998-3874",
    "geo": {
      "lat": "-37.3159",
      "lng": "81.1496"
    }
  },
  "phone": "1-770-736-8031 x56442",
  "website": "hildegard.org",
  "company": {
    "name": "Romaguera-Crona",
    "catchPhrase": "Multi-layered client-server neural-net",
    "bs": "harness real-time e-markets"
  }
}

これがこうなります

curl http://jsonplaceholder.typicode.com/users/1 | jt

出力

root
├──── "id": 1
├──── "name": "Leanne Graham"
├──── "username": "Bret"
├──── "email": "Sincere@april.biz"
├──── "address"

        ├──── "name": "Romaguera-Crona"
        ├──── "catchPhrase": "Multi-layered client-server neural-net"
        └──── "bs": "harness real-time e-markets"

これとは別ですが、もっと便利なやつで jq というものがあります。
