命令插件(Commands)

As of version 2.5.0 , Jekyll can be extended with plugins which provide subcommands for the jekyll executable. This is possible by including the relevant plugins in a Gemfile group called :jekyll_plugins:

group :jekyll_plugins do
  gem "my_fancy_jekyll_plugin"
end

Each Command must be a subclass of the Jekyll::Command class and must contain one class method: init_with_program. An example:

class MyNewCommand < Jekyll::Command
  class << self
    def init_with_program(prog)
      prog.command(:new) do |c|
        c.syntax "new [options]"
        c.description 'Create a new Jekyll site.'

        c.option 'dest', '-d DEST', 'Where the site should go.'

        c.action do |args, options|
          Jekyll::Site.new_site_at(options['dest'])
        end
      end
    end
  end
end

Commands should implement this single class method:

Method	Description
`init_with_program`	This method accepts one parameter, the `Mercenary::Program` instance, which is the Jekyll program itself. Upon the program, commands may be created using the above syntax. For more details, visit the Mercenary repository on GitHub.com.
