Clojure Polymorphism

by Paul Stadig

Improve your skill at designing polymorphic Clojure applications.

When it comes to Clojure there are many tutorials, websites, and books about how to get started (language syntax, set up a project, configure your IDE, etc.). There are also many tutorials, websites, and books about how language features work (protocols, transducers, core.async). There are precious few tutorials, websites, and books about when and how to use Clojure's features.

This is a comparative architecture class. I assume you are familiar with Clojure and even a bit proficient at it. I will talk about Clojure's polymorphic tools. I will use some example problems, solve them with different tools, and then pick them apart for what is good and what is bad. There will not be one right answer, but you will learn principles about when to appropriately apply Clojure's polymorphic tools.

A well-written explanation of polymorphism in Clojure. Paul jumps almost immediately into examples and demonstrates a handful of different approaches. He rattles off pros and cons of the different approaches and provides guidelines for when to use each.

Krátká, ale informace nabušená kniha s ukázkou několika přístupů jak řešit v Clojure polymorfismus. U každého přístupu jsou rozebrány přínosy i co za to platíme. Pokud ještě nemáte design patterns pro tvorbu funkcionálních kompozicí a abstrakcí v krvi, určitě vás tato kniha obohatí.

Basically an extended, really well edited blog post. I like the style of showing the code for multiple ways of implementing the client and backend for a simple service, then discussing the pros and cons.

I love this book and hope for more like it. The author jumps in with both feet; I personally like a little more context.
