Ruby on Rails

Thor is a toolkit for building powerful command-line interfaces.

It always been used for single command line. If I want to use it in a rails project, for example:

lib/tasks/my_cli.rb

    require "thor"
     
    class MyCLI < Thor
      desc "hello NAME", "say hello to NAME"
      def hello(name)
        puts "Hello #{name}"
      end
    end

Where to put the `MyCLI.start(ARGV)`?

If I put it under that file(`lib/tasks/my_cli.rb`), when I run my rspec test, it will show me the command message:

    Commands:
      rspec help [COMMAND]   # Describe available commands or one specific command
      rspec hello NAME       # say hello to NAME

I don't want to see it in my `bundle exec rspec`, so I moved the `MyCLI.start(ARGV)` to `bin/rails`. It looks well. But after I do this:

    $ ./bin/rails s -b 0.0.0.0
    $ [CTRL+C]

I saw this message:

    => Booting Thin
    => Rails 4.2.0 application starting in development on http://0.0.0.0:3000
    => Run `rails server -h` for more startup options
    => Ctrl-C to shutdown server
    Thin web server (v1.6.3 codename Protein Powder)
    Maximum connections set to 1024
    Listening on 0.0.0.0:3000, CTRL+C to stop
    ^CStopping ...
    Exiting
    Could not find command "_b".

What does it mean:

    Could not find command "_b".

So, I don't know a best practice about how to use thor in a rails project.
