当面は技術的なことしか書かない

jqコマンドが存外に便利かもしれないという話

Mac

JSONを表示さすURLをcurlで叩いたときはこんな感じになると思うんです。

$ curl http://restro.nalwaya.com/restaurants/search.json\?city\=Chicago
[{"name":"Dolalli","thumb_url_image":"http://restro.nalwaya.com/system/restaurants/avatars/000/000/001/thumb/Restaurant-Blue-2-icon.png?1374505105","food_type":"American","latitude":37.0,"longitude":-22.0,"desc":"Traditional American joint "},{"name":"Pizzamast","thumb_url_image":"http://restro.nalwaya.com/system/restaurants/avatars/000/000/002/thumb/Restaurant-Blue-icon.png?1374505157","food_type":"Italian","latitude":30.0,"longitude":-122.0,"desc":"200 type of Pizzas"},{"name":"More Pizza","thumb_url_image":"http://restro.nalwaya.com/system/restaurants/avatars/000/000/003/thumb/pizza-slice-icon.png?1374505545","food_type":"American","latitude":111.0,"longitude":-10.0,"desc":"Pizza at your door step"}]

JSONが1行で表示されちゃっているから、何がなんだか分からないってことはないけど、
すごく読みづらい。

で、これをきれいに表示さすのがjqコマンドであります。

homebrewなら、このコマンド一発でおkだお。

$ brew install jq
$ curl http://restro.nalwaya.com/restaurants/search.json\?city\=Chicago | jq .
