使用thor进行交互提示

Question

我想以某种方式要求用户说出他们的flickr_id，flickr_apikey之类的东西，但我很乐意在我的install命令下这样做，这样它就不会因为所有的参数而变得如此冗长和繁重。

所以就像这样

$ 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}

诸若此类?你明白我的意思了吗?你能做到吗？

Answer 1

它确实可以！

您正在寻找ask。

举个例子：

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

Answer 2

也可以将颜色设置为符号

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'
