與 thor 的交互式提示

Question

我想以某種方式要求用戶說出他們的 flickr_id、flickr_apikey 和那些東西，但我很樂意在我的安裝命令下這樣做，所以它不會因為所有參數而最終成為如此長而沉重的行。

所以像

$ thor PhotoonRails:install
We're about to install your system.. blaa, blaa, blaa...
We have to know you're Flick ID, get i here http://idgettr.com/
Flickr ID: {here you should type your id}

We also has to know you're flick api key, make one here ...
API Key: {here you should type your key}

等等？ 你明白這個想法嗎，它可以做到嗎？

Answer 1

確實可以！

您正在尋找ask 。

一個例子：

class PhotoonRails < Thor
  desc "install", "install my cool stuff"
  def install
    say("We're about to install your system.. blaa, blaa, blaa... We have to know you're Flick ID, get i here http://idgettr.com")
    flickr_id = ask("Flickr ID: ")

    say("We also has to know you're flick api key, make one here ...")
    flickr_api_key = ask("API Key: ")

    # validate flickr creds
    # do cool stuff

    say("Complete!", GREEN)
  end
end

Answer 2

也可以將顏色設置為符號

say "Caution!", :yellow
ask 'Agreed?', :bold

# Choose limit:
ask "We have noticed.", :green, limited_to: ['proceed', 'exit']

# Default value (possible without :blue)
ask 'Type app name', :blue, default: 'blog'
