我正在使用thor创建一个CLI应用程序。它进展顺利,但现在我坚持使用子命令功能。
github wiki中没有任何内容可以搜索,但没有任何帮助。
那么,有人可以展示或指出如何实现子命令功能吗?

从该站点(编辑一点以节省空间并突出显示子命令用法):
module GitCLI class Remote ", "Adds a remote named for the repository at " option :t, :banner => "" option :m, :banner => "" options :f => :boolean, :tags => :boolean, :mirror => :string def add(name, url) # implement git remote add end desc "rename ", "Rename the remote named to " def rename(old, new) end end class Git [...]", "Download objects and refs from another repository" options :all => :boolean, :multiple => :boolean option :append, :type => :boolean, :aliases => :a def fetch(respository, *refspec) # implement git fetch here end desc "remote SUBCOMMAND ...ARGS", "manage set of tracked repositories" subcommand "remote", Remote ### SUBCOMMAND USED HERE... end end

尝试这样的事情(文件test.rb):
#!/usr/bin/env ruby
require 'rubygems'
require 'thor'
require 'thor/group' # This is required -- it's not a bug, it's a feature!
class Bar < Thor
desc "baz", "Whatever"
def baz
puts "Hello from Bar"
end
end
class Foo < Thor
desc "go", "Do something"
def go
puts "Hello there!"
end
register Bar, :bar, "bar", "Do something else"
end
if __FILE__ == $0
Foo.start
end
表现如下:
> test.rb
Tasks:
test.rb bar # Do something else
test.rb go # Do something
test.rb help [TASK] # Describe available tasks or one specific task
> test.rb go
Hello there!
> test.rb bar
Tasks:
test.rb baz # Whatever
test.rb help [COMMAND] # Describe subcommands or one specific subcommand
> test.rb bar baz
Hello from Bar
> test.rb baz
Could not find task "baz".

(这大部分按预期工作,除了“test.rb bar”的帮助信息不太正确,恕我直言。我认为它应该说“test.rb bar baz ...”,而不是“test。 rb baz ......“。)
希望这有帮助!
