如何将Thor :: Group注册为带参数的子命令

Question

这个问题从这里开始.但随着我对托尔的了解越来越多,这一情

我正在尝试创建一个带有参数的Thor :: Group子命令.奇怪的是,如果没有参数,它就有效.

我可以使用Thor :: Group作为子命令吗？

当我键入时,这有效: foo counter

富/斌/富

module Foo
  class CLI < Thor
    register(Counter, 'counter', 'counter', 'Count up from the 1.')
  end

  class Counter < Thor::Group
    desc "Prints 1 2"

    def one
      puts 1
    end

    def two
      puts 2
    end

  end

end

Foo::CLI.start

但是当我键入时,这不起作用: foo counter 5

module Foo
  class CLI < Thor
    register(Counter, 'counter', 'counter <number>', 'Count up from the input.')
  end

  class Counter < Thor::Group
    argument :number, :type => :numeric, :desc => "The number to start counting"
    desc "Prints 2 numbers based on input"

    def one
      puts number + 0
    end

    def two
      puts number + 1
    end

  end


end

Foo::CLI.start

它回复: counter was called incorrectly. Call as foo counter number

我有一个解决方案.而不是使用Thor :: Group我正在使用Invocations

bin/foo看起来像这样:

#!/usr/bin/env ruby

require 'foo'

Foo::CLI.start

lib/cli.rb - 将'generate'注册为基本命令foo的子任务:

module Foo
  class CLI < Thor
    register(Generate, 'generate', 'generate [something]', 'Type foo generate for more help.')
  end
end

lib/generate.rb看起来像这样:

module Foo

  class Generate < Thor

    desc "project [name]", "Prints the project making step"
    def project(name)
      puts "making first project file #{name}"
      invoke :config
      invoke :project_sub
    end

    desc "config [name]", "Prints the config making step"
    def config(name)
      puts "making first config file #{name}"
      invoke :project_sub
    end

    desc "project_sub [name]", "Prints the project_sub making step"
    def project_sub(name)
      puts "making subsystem file #{name}"
    end

    def self.banner(task, namespace = false, subcommand = true)
       task.formatted_usage(self, true, subcommand).split(':').join(' ')
    end

  end

end

现在我可以输入: foo generate project fred

它会输出:

> making first project file fred
> making first config file fred
> making subsystem file fred

注意横幅覆盖.这意味着键入:foo generate project无效或缺少args将给出正确的帮助消息:

"project" was called incorrectly. Call as "foo generate project [name]".

而不是

"project" was called incorrectly. Call as "foo project [name]".
