與托爾的交互式提示

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，但是id很樂意在我的安裝命令下執行它，所以它不會最終變得如此漫長而沉重因爲有理由支持。與托爾的交互式提示

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？你有沒有想到，可以做到嗎？

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

我的好！這很容易！所有的工作都很酷，除了說（「完成！」，綠色） - 但非常感謝你！ – 2011-01-05 15:25:28

哎呀，試圖得到幻想。噢，很高興它解決了！ – hornairs 2011-01-05 15:27:04

而不是綠色，你只需寫「\ e [32m」:-)！ – 2011-01-05 15:27:54

也可以設置顏色爲標誌可用顏色的

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, deafult: 'blog'
