与托尔的交互式提示

我想以某种方式要求用户说出他们的flickr_id，flickr_apikey和那些东西，但是id很乐意在我的安装命令下执行它，所以它不会最终变得如此漫长而沉重因为有理由支持。与托尔的交互式提示

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？你有没有想到，可以做到吗？

确实可以！

您正在寻找ask。

一个例子：

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！这很容易！所有的工作都很酷，除了说（“完成！”，绿色） - 但非常感谢你！ – 2011-01-05 15:25:28

哎呀，试图得到幻想。噢，很高兴它解决了！ – hornairs 2011-01-05 15:27:04

而不是绿色，你只需写“\ e [32m”:-)！ – 2011-01-05 15:27:54

也可以设置颜色为标志可用颜色的

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'
