为什么Thor不识别我的命令行选项？

Question

I am writing some rake tasks with Thor. In these thor tasks I am specifying some method options to make the command line more robust but the problem that I am running into is that thor is not recognizing my commands.

Here is an example task:

module ReverificationTask
  class Notifications < Thor
     option :bounce_threshold, :aliases => '-bt', :desc => 'Sets bounce rate', :required => true, :type => :numeric
     option :num_email, :aliases => '-e', :desc => 'Sets the amount of email', :required => true, :type => :numeric

     desc 'resend_to_soft_bounced_emails [BOUNCE_THRESHOLD] [NUM_EMAIL]'

     def resend_to_soft_bounced_emails(bounce_rate, amount_of_email)
        Reverification::Process.set_amazon_stat_settings(bounce_rate, amount_of_email)
        Reverification::Mailer.resend_soft_bounced_notifications
     end
  end
end

I have followed the Thor official web page on 'Options' WhatisThor and when I run thor help reverification_task:notifications:resend_to_soft_bounced_emails

It correctly outputs what I would expect to see in the command line argument:

Usage:
thor reverification_task:notifications:resend_to_soft_bounced_emails [BOUNCE_THRESHOLD] [NUM_EMAIL] -bt, --bounce-threshold=N -e, --num-email=N

Options:
  -bt, --bounce-threshold=N  # Sets bounce rate
  -e, --num-email=N          # Sets the amount of email

When I execute thor reverification_task:notifications:resend_to_soft_bounced_emails -bt 20 -e 2000 this is the response:

No value provided for required options '--bounce-threshold'

What is the problem here? Any help would be greatly appreciated. Thanks.

You just mixed options with arguments. If you add arguments to your thor task definition, as you did in def resend_to_soft_bounced_emails(bounce_rate, amount_of_email) , you need to call them as command line arguments too:

thor reverification_task:notifications:resend_to_soft_bounced_emails 20 2000

But you rather wanted to use options (passed on the command line with - prefixes), so you should remove the arguments from your task definition and refer to the options using the options hash:

def resend_to_soft_bounced_emails
  Reverification::Process.set_amazon_stat_settings(options[:bounce_threshold], 
                                                   options[:num_email])
  Reverification::Mailer.resend_soft_bounced_notifications
end
