Question

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 id' 最乐意在我的安装命令下这样做，这样它就不会因为所有的原因而变得如此冗长和粗重论点。

类似的东西

$ 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？你明白这个想法了吗？可以实现吗？

Answer 1

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
