使用map或each提高CLI应用程序散列返回的可读性

Question

我的应用程序返回一个键和值的散列，我希望它能以一种易于阅读的方式显示它们。有没有办法让它在显示信息的同时显示密钥。因此，如果我搜索一个菌株，它将返回类似于下面的内容

ID: ID号名称:名称种族:种族口味:口味等。

它打印的内容示例：

Choosing ALL returns a LOT of data, be ready for it!
By what strain attribute would you like to search? Flavor
Which Flavor would you like to search for? If nothing is returned, your search term isn't one thats accepted. coffee

This is what I have so far: 

```ruby

选择= AttributeParser.new("http://strainapi.evanbusse.com/rvxnT8j/strains/search/#{first_choice}/#{encoded_second_choice}")

结果= selection.parse_json

将results.map {|x| x.values}.uniq

what I've tried and its results

```javascript

选择全部返回大量数据，做好准备！

您想要搜索哪种类型的属性？风味

你想找哪种口味的？如果没有返回任何内容，则表示您的搜索词不被接受。咖啡

有一个很棒的控制台库，叫做Hirb，可以用来实现这个目的。例如，假设您的散列数组是data格式的，我们可以这样做：

require 'hirb'
puts Hirb::Helpers::AutoTable.render(data, fields: %w|id name flavor race|)

结果：

+-----+--------------------------+--------+--------+
| id  | name                     | flavor | race   |
+-----+--------------------------+--------+--------+
| 156 | Bhang Chocolope          | Coffee | sativa |
| 262 | Black '84                | Coffee | indica |
| 353 | Blue Ox                  | Coffee | indica |
| 369 | Blue Zombie              | Coffee | indica |
| 478 | Caramel Candy Kush       | Coffee | hybrid |
| 479 | Caramel Kona Coffee Kush | Coffee | indica |
| 480 | Caramelicious            | Coffee | hybrid |
