这是我的Ruby代码:
require 'thor'
require 'thor/group'
module CLI
class Greet < Thor
desc 'hi', 'Say hi!'
method_option :name, :type => :string, :description => 'Name to greet', :default => 'there'
def hi
puts "Hi, #{options[:name]}!"
end
desc 'bye', 'say bye!'
def bye
puts "Bye!"
end
end
class Root < Thor
register CLI::Greet, 'greet', 'greet [COMMAND]', 'Greet with a command'
end
end
CLI::Root.start
这是输出:
C:\temp>ruby greet.rb help greet
Usage:
greet.rb greet [COMMAND]
Greet with a command
如何让它看起来像这样?
C:\temp>ruby greet.rb help greet
Usage:
greet.rb greet [COMMAND]
--name Name to greet
Greet with a command
答案 0 :(得分:7)
你有两件事在这里发生。首先,您已将--name指定给方法,而不是指定给整个CLI::Greet
类。因此,如果您使用命令:
ruby greet.rb greet help hi
你得到了
Usage:
greet.rb hi
Options:
[--name=NAME]
# Default: there
Say hi!
哪个,是的,是错的 - 它在帮助中没有子命令。在托尔有一个bug申请。但是,它正确地显示了方法选项。
然而,您正在寻找的是一种类方法。这是为整个CLI::Greet
类定义的方法,而不仅仅是#hi
方法。
你这样做:
require 'thor'
require 'thor/group'
module CLI
class Greet < Thor
desc 'hi', 'Say hi!'
class_option :number, :type => :string, :description => 'Number to call', :default => '555-1212'
method_option :name, :type => :string, :description => 'Name to greet', :default => 'there'
def hi
puts "Hi, #{options[:name]}! Call me at #{options[:number]}"
end
desc 'bye', 'say bye!'
def bye
puts "Bye! Call me at #{options[:number]}"
end
end
class Root < Thor
register CLI::Greet, 'greet', 'greet [COMMAND]', 'Greet with a command'
tasks["greet"].options = CLI::Greet.class_options
end
end
CLI::Root.start
这样,ruby greet.rb help greet
返回
Usage:
greet.rb greet [COMMAND]
Options:
[--number=NUMBER]
# Default: 555-1212
Greet with a command
请注意,此处仍需要黑客攻击:tasks["greet"].options = CLI::Greet.class_options
中的CLI::Root
行。还有一个bug在托尔也提出了这个问题。
