feat: select different config via command line

[nodomain]

Hi,

since I use YNAB for my wife and myself, I needed the possibility to select a different config file via command line.
This is my first Ruby "code" - works for me, YMMV.

Perhaps you can improve my solution ;)

I'm wondering, maybe it would be nicer to introduce a config directory if there are multiple config files.

Maybe what could happen is:

• the script looks for a config.yml by default and if it doesn't find any ./config.yml and no arguments are given, it throws an error explaining the two ways of configuring it
• when an argument is given, it never checks for the ./config.yml, it could directly try to access config/your-argument.yml

What do you think?

I really like that idea, amazing that you started this PR!

Cool. Will have to look how to do this with Ruby. I am more a Python/Bash guy ;)

I was thinking about the code a bit and what you could do is to extract all the config-file related logic to a method and then call it. Could be something like this:

# Reads the settings from the yaml file
class Settings
  def self.all
    @settings ||= begin
      YAML.load_file(File.join('.', config_path))
    end
  end

  def self.config_path
    return "spec/config.test.yml" if ENV['ENV'] == 'test'
    return "config/#{ARGV[0]}.yml" if ARGV[0]
    "config.yml"
  end
end

The YAML.load_file should already throw an understandable error, so I don't think we would need to handle it. Let me know what you think

Same as above - great idea but no idea how to do this in Ruby. Will have to look into it.
