如何创建thor :: group生成器作为my_command的参数 [英] How do I create thor::group generators as args of my_command

问题描述

  foo生成项目$ b在我的宝石中，我想要一个带有args的可执行命令，如下所示：
 $ b foo生成配置
 foo say_hi 
  

所以我做了

foo / bin / foo

 ＃！/ usr / bin / env ruby​​ 
 require'foo'
 Foo :: Foo.start 
  

foo / lib / thor / foo.rb中的Foo文件

  module Foo 
类Foo< Thor 
 
 descgenerate [WHAT]
 def generate（* args）
 
 end 
 
 descsay_hi
 def say_hi（* args）
 .... 
结束
 
结束
结束
  

foo / lib / thor / generators / project.rb
和 foo / lib / thor / generators / config。 rb

在哪里我想指定从Thor :: Group继承的类，例如katz示例...

  module Foo 
模块生成器
 class Project< Thor :: Group 
包括Thor :: Actions 
 .... 
 end 
 end 
 end 
  

所以我的问题是：我如何设置，以便可以从可执行文件调用这些生成器，如：

  foo生成配置
  

我在正确的轨道上甚至？理想情况下，自行输入 foo 应该为 say_hi 和所有生成器提供帮助。

解决方案

我一开始也遇到了麻烦。以下是我开始使用的模式：

$ cat cli.rb

 ＃！/ usr / bin / env ruby​​ 
 require'rubygems'
 require'thor'
 require'thor / group'
 
模块CLI 
 class Greeter< Thor :: Group 
 def say_hi 
 sayHi
 end 
 def say_goodbye 
 sayGoodbye
 end 
 end 
结束
 
模块CLI 
 class Crud< Thor 
 desc'create'，'创建一个子物件'
 def创建
说创建子物件
结束
 
 desc'删除'，'删除子物件'
 def delete 
说删除子物件
结束
 
结束
结束
 
模块CLI 
 class Root< Thor 
注册CLI :: Greeter，'greet'，'greet'，'执行多步骤子任务'
注册CLI :: Crud，'crud'，'crud [COMMAND]'，'Delegates到一个子命令'
 end 
 end 
 
 CLI :: Root.start 
  

$ ./cli.rb

 任务：
 cli.rb crud [ COMMAND]＃委托给一个子命令
 cli.rb greet＃执行多步骤子任务
 cli.rb help [任务]＃描述可用任务或一个特定任务
  

$ ./cli.rb greet

  Hi 
 Goodbye 
  

$ ./cli.rb crud

 任务：
 cli.rb crud create＃创建一个子物件
 cli.rb crud delete＃删除一个子物件，事物
 cli.rb crud help [命令]＃描述子命令或一个特定的子命令
  

$ ./cli.rb crud create

 创建一个sub-thi ng 
  

$ ./cli.rb crud删除

 删除子物件
  

In my gem I'd like to have a an executable command with args like so:

foo generate project
foo generate config
foo say_hi

So I made

foo/bin/foo

#!/usr/bin/env ruby
require 'foo'
Foo::Foo.start

And the Foo file in foo/lib/thor/foo.rb

module Foo 
  class Foo < Thor

    desc "generate [WHAT]"
    def generate(*args)

    end

    desc "say_hi"
    def say_hi(*args)
       ....
    end

  end
end

And foo/lib/thor/generators/project.rb And foo/lib/thor/generators/config.rb

Where I'd like to specify classes inherited from Thor::Group like katz examples ...

module Foo
  module Generators
    class Project < Thor::Group
      include Thor::Actions
      ....
    end
  end
end

So my question is: How do I set things up so that I can call those generators from the executable like:

foo generate config

Am I on the right track even? Ideally, typing foo on its own should give help for say_hi and for all the generators.

解决方案

I had trouble getting this to work at first, too. Here's the pattern that I've started using:

$ cat cli.rb

#!/usr/bin/env ruby
require 'rubygems'
require 'thor'
require 'thor/group'

module CLI
  class Greeter < Thor::Group
    def say_hi
      say "Hi"
    end
    def say_goodbye
      say "Goodbye"
    end
  end
end

module CLI
  class Crud < Thor
    desc 'create', 'Creates a sub-thing'
    def create
      say "Creating a sub-thing"
    end

    desc 'delete', 'Deletes a sub-thing'
    def delete
      say "Deleting a sub-thing"
    end

  end
end

module CLI
  class Root < Thor
    register CLI::Greeter, 'greet', 'greet', 'Executes a multi-step subtask'
    register CLI::Crud, 'crud', 'crud [COMMAND]', 'Delegates to a sub-command'
  end
end

CLI::Root.start

$ ./cli.rb

Tasks:
  cli.rb crud [COMMAND]  # Delegates to a sub-command
  cli.rb greet           # Executes a multi-step subtask
  cli.rb help [TASK]     # Describe available tasks or one specific task

$ ./cli.rb greet

Hi
Goodbye

$ ./cli.rb crud

Tasks:
  cli.rb crud create          # Creates a sub-thing
  cli.rb crud delete          # Deletes a sub-thing
  cli.rb crud help [COMMAND]  # Describe subcommands or one specific subcommand

$ ./cli.rb crud create

Creating a sub-thing

$ ./cli.rb crud delete

Deleting a sub-thing
