Thor Add-ons

Extend Thor with useful Add-ons

gem install thor-addons

The Options module allows you to read the CLI options from a configuration file or/and environment variables.

include the Options module to your Thor class.

require 'thor'
require 'thor_addons'

class CLI < Thor
  include ThorAddons::Options

  class_option :config_file, type: :string, default: "config.yml", desc: "Configuration file for the CLI"

  method_option :bar, type: :string, default: "biz", desc: "some option"
  desc "foo", "install one of the available apps"
  def foo
    # code
  end
end

In the example above the --bar option will be read from the configuration file --config-file

foo:
  bar: "zip"

and via the environment variable BAR

if you want to disable the configuration file you need to set in your class

def with_config_file?
  false
end

and for disabling the environment variables

def with_env?
  false
end

you can also have environment variables aliases, by setting

def envs_aliases
  # source => alias
  { "BAR" => "MY_BAR" }
end

The cli will set bar with the value of BAR or MY_BAR if BAR is not set.

This module will set the options in this order: cli options, config file, environment variables
