Q: What are the performance costs of using OOP in Elixir?

Since it adds a macro-based layer on top of Elixir, it introduces overhead compared to native functional code. The library isn't optimized, so performance may suffer in resource-intensive scenarios.

Q: OOP library vs standard Elixir modules: which should I choose?

For serious development, choose standard Elixir modules as they are idiomatic and optimized. The OOP library is best for humor, education, or understanding paradigm mappings, not for production code.

Q: How to add the OOP library to an existing Elixir project?

Add {:oop, "~> 0.1.0"} to your mix.exs dependencies, then import OOP in your modules to start defining classes with the class macro and using dot notation for methods.

Question 1

Is the OOP Elixir library safe for production use?

Accepted Answer

No, the README warns against it, stating it's a parody or educational tool. It's not designed for stability or performance in real applications, so use standard Elixir modules instead.

Question 2

How do I implement multiple inheritance with wojtekmach/oop?

Accepted Answer

Use the syntax class Centaur < [Human, Horse] as shown in the README example. It allows inheriting from multiple parent classes, simulating multiple inheritance in Elixir.

Question 3

What are the performance costs of using OOP in Elixir?

Accepted Answer

Since it adds a macro-based layer on top of Elixir, it introduces overhead compared to native functional code. The library isn't optimized, so performance may suffer in resource-intensive scenarios.

Question 4

OOP library vs standard Elixir modules: which should I choose?

Accepted Answer

For serious development, choose standard Elixir modules as they are idiomatic and optimized. The OOP library is best for humor, education, or understanding paradigm mappings, not for production code.

Question 5

How to add the OOP library to an existing Elixir project?

Accepted Answer

Add {:oop, "~> 0.1.0"} to your mix.exs dependencies, then import OOP in your modules to start defining classes with the class macro and using dot notation for methods.

Question 6

Can OOP library handle polymorphism in Elixir?

Accepted Answer

Yes, through inheritance and method overriding as demonstrated in the examples, but it's simulated and doesn't align with Elixir's native pattern matching and functional polymorphism.

Question 7

Why use an OOP library in a functional language like Elixir?

Accepted Answer

Primarily for educational purposes, parody, or to explore how OOP concepts translate to functional environments, as highlighted in the philosophical notes referencing Alan Kay and Joe Armstrong.
