Interactive prompt with thor

Question

I want to somehow ask the user to say their flickr_id, flickr_apikey and that stuff, but id' be most happy to do it under my install command so it dosn't end up being such a long and heavy line because of alle the arguments.

so something like

$ 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}

and so on? Do you get the idea, and can it be done?

Answer 1

Indeed it can!

You are looking for ask.

An example:

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

Also possible to set color as a symbol

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'
