Dynamically remove mixin ancestor from class

How do I properly use the Ruby DelegateClass to wrap YAML::Store?

Where is SimpleDelegator in Ruby 2.7?

QUESTION

Dynamically remove mixin ancestor from class

Asked 2022-Feb-06 at 01:52

I am trying to develop a simple card game console application in ruby as a pet project. One of the interactions I would like to add to this card game is something along the lines of "During your turn, you can buy cards as if they cost X less". Now, I thought about modelling this behaviour with the help of mixin decorators. Assuming the following class:

What you are trying to achieve is a very bad pattern. You should almost never use prepend or include dynamically, but model your code around the concepts you (and people possibly reading your code) do understand.

What you probably want to do is to create (some kind of) a Delegator called CardAffectedByEnvironment - and then instead of doing Card.new(x), you will always do CardAffectedByEnvironment.new(Card.new(x), env), where env will keep all your state changes, or add a method real_cost that would calculate things based on your cost and environment and use this method.

Below is a code with CardAffectedByEnvironment that would maybe describe better how I would assume it would work:

QUESTION

How do I properly use the Ruby DelegateClass to wrap YAML::Store?

Asked 2021-Sep-30 at 12:53

Testing Environment

I've tried this in both Ruby 3.0.2 and Ruby 2.73, with similar results. It shouldn't matter for the problem at hand, as I've also tried this under different shells and ruby managers, but this is primarily being tested under:

fish, version 3.3.1
chruby: 0.3.9
chruby-fish: 0.8.2
macOS 11.6

Describing the Problem (Code and Errors in Subsequent Sections)

I'm trying to use the poorly (or possibly even undocumented) DelegateClass from the Delegator class to create a facade for YAML::Store that allows me to read and write arbitrary keys to and from a YAML store. However, I clearly don't understand how to properly delegate to the YAML::Store instance, or to override or extend the functionality in the way that I want.

For simplicity, I wrote my example as a self-executing Ruby file names example.rb, so please scroll to the end to see the actual call to the classes. I'm hoping that my mistake is fairly trivial, but if I'm fundamentally misunderstanding how to actually perform the delegation of CollaboratorWithData#write and ollaboratorWithData#read to MultiWriter, please educate me.

Note: I know how to solve this problem by simply treating YAML::Store as an object instantiated within my class, or even as a separate object that inherits from YAML::Store (e.g. class MultiWriter < YAML::Store) but I'm very much trying to understand how to properly use Forwardable, SimpleDelegator, and Delegate to wrap objects both in the general case and in this particular use case.

To go over some of your questions regarding delegation:

Forwardable: This module when extended allows you to specify specific methods that should be delegated to a designated Object (most often an instance variable) Example:

Where is SimpleDelegator in Ruby 2.7?

Asked 2020-Feb-29 at 19:12

I have been using the SimpleDelegator class for various things. But I noticed, Ruby 2.7 (ArchLinux x86_64) doesn't come with the SimpleDelegator class (no Delegator either).

My program:

The Delegator and SimpleDelegator classes aren't core classes like Array or Mutex. They're part of the delegate standard library which needs to be loaded first: require 'delegate'.

It happened to work in older Ruby versions as they came with an older RubyGems version by default. RubyGems is automatically loaded since Ruby 1.9 and until 3.1.0 that meant delegate was loaded indirectly. Updating RubyGems or running ruby with --disable=gems should cause the exact same issue with Ruby <= 2.6 too. irb also loads several standard libraries: delegate but also timeout and many more.

Programming languages with a similar mechanism like C++ also have this issue: instead of load/require there's #include, including a standard library header might include another one, then a newer version might not include the other header anymore and user code relying on the old behavior fails to compile.
