Application with default settings

[davydovanton]

Now we have a simple problem: how to set up default values for each abilities instance in one place?

I sugest to use something like this:

class ProjectAbilityApplication < Kan::Application
  default_options logger: MyLogger.new
end

After that we can initialize:

• default application class

Kan::Application.new(
  comment: Comments::Abilities.new
) # => will use default Logger

• custom application class

ProjectAbilityApplication.new(
  comment: Comments::Abilities.new
) # => will use default MyLogger

• custom application class with other value

ProjectAbilityApplication.new(
  comment: Comments::Abilities.new(logger: MyOtherLogger.new)
) # => will use MyOtherLogger

WDYT?

UPD agter small talk with @apotonick: Maybe we need to use instance variable for settings and #call for generating a builder class 🤔

Kan::Application.new.call(
  comment: Comments::Abilities.new
) # => will use default Logger

Kan::Application.new(logger: MyLogger.new).call(
  comment: Comments::Abilities.new
) # will use MyLogger

Kan::Application.new(logger: MyLogger.new).call(
  comment: Comments::Abilities.new(logger: MyOtherLogger.new)
) # => will use MyOtherLogger

Hey, I like the third step where you can override it as an argument, but I don't understand how the ProjectAbilityApplication manages to set a MyLogger on the Comments ability object. Are you using a writer internally for that? Because that I think I wouldn't like.
