Examples

Params

class BaseClass

  include Ronin::Core::Params::Mixin

end

class MyModule < BaseClass

  param :str, desc: 'A basic string param'

  param :feature_flag, Boolean, desc: 'A boolean param'

  param :enum, Enum[:one, :two, :three],
               desc: 'An enum param'

  param :num1, Integer, desc: 'An integer param'

  param :num2, Integer, default: 42,
                       desc: 'A param with a default value'

  param :num3, Integer, default: ->{ rand(42) },
                        desc: 'A param with a dynamic default value'

  param :float, Float, 'Floating point param'

  param :url, URI, desc: 'URL param'

  param :pattern, Regexp, desc: 'Regular Expression param'

end

mod = MyModule.new(params: {num1: 1, enum: :two})
mod.params
# => {:num2=>42, :num3=>25, :num1=>1, :enum=>:two}

CLI

Define a main command for ronin-foo:

# lib/ronin/foo/cli.rb
require 'command_kit/commands'
require 'command_kit/commands/auto_load'

module Ronin
  module Foo
    class CLI

      include CommandKit::Commands
      include CommandKit::Commands::AutoLoad.new(
        dir:       "#{__dir__}/cli/commands",
        namespace: "#{self}::Commands"
      )

      command_name 'ronin-foo'

      command_aliases['ls'] = 'list'
      # ...

    end
  end
end

Add a bin/ronin-foo file (don't forget to chmod +x it) that invokes the main command:

#!/usr/bin/env ruby

root = File.expand_path(File.join(__dir__,'..'))
if File.file?(File.join(root,'Gemfile.lock'))
  Dir.chdir(root) do
    begin
      require 'bundler/setup'
    rescue LoadError => e
      warn e.message
      warn "Run `gem install bundler` to install Bundler"
      exit -1
    end
  end
end

require 'ronin/foo/cli'
Ronin::Foo::CLI.start

Define a common command class for all ronin-foo's commands:

# lib/ronin/foo/cli/command.rb
require 'ronin/core/cli/command'

module Ronin
  module Foo
    class CLI
      class Command < Core::CLI::Command

        man_dir File.join(__dir__,'..','..','..','..','man')

      end
    end
  end
end

Define a list sub-command under the ronin-foo main command:

# lib/ronin/foo/cli/commands/list.rb
require 'ronin/foo/cli/command'

module Ronin
  module Foo
    class CLI
      module Commands
        class List < Command

          usage '[options] [NAME]'

          argument :name, required: false,
                          desc:     'Optional name to list'

          description 'Lists all things'

          man_page 'ronin-foo-list.1'

          def run(name=nil)
            # ...
          end

        end
      end
    end
  end
end

Test it out:

$ ./bin/ronin-foo
Usage: ronin-foo [options] [COMMAND [ARGS...]]

Options:
    -h, --help                       Print help information

Arguments:
    [COMMAND]                        The command name to run
    [ARGS ...]                       Additional arguments for the command

Commands:
    help
    list, ls
$ ./bin/ronin-foo ls

CLI::CommandShell

Define a custom command shell:

class HTTPShell < Ronin::Core::CLI::CommandShell

  shell_name 'http'

  command :get, usage: 'PATH [HEADERS...]',
                summary: 'Sends a GET request'
  def get(path,*headers)
    # ...
  end

  command :post, usage: 'PATH DATA [HEADERS...]',
                 summary: 'Sends a POST request'
  def post(path,data,*headers)
    # ...
  end

end

Then start it:

HTTPShell.start

http> get /foo
...
http> post /foo var=bar
...
