magicum

1. Latin: the nominative neuter singular of magicus.

magicus

1. magic, magical.

from Wiktionary, the free dictionary

magicum is a libre Magic: The Gathering game rules engine implementation, written in Clojure.

This project is currently in a very early development stage, so there is not much functionality to be seen... yet ;-)

IPA^(key): /'ma.ʝi.kum/, [ˈma.ʝɪ.kʊm]

Whereas the original Classical Latin word should be pronounced /ˈma.ɡi.kum/ or [ˈma.ɡɪ.kʊm], as the origin language of the original game's name is English, we use an English-like pronunciation.

When released, this project will follow the version scheme MAJOR.MINOR.COMMITS, where MAJOR and MINOR provide some relative indication of the size of the change, but do not follow semantic versioning, and COMMITS is an ever-increasing counter of commits since the beginning of this repository.

In general, after release all changes will endeavor to be non-breaking (by moving to new names rather than by breaking existing names). For a more detailed rationale, please refer to Rich Hickey's "spec-ulation Keynote" from Clojure/conj 2016.

At this point, probably too many. To be discovered! :-)

• Use advanced programming techniques, such as formal specifications, and property-based and generative testing as much as possible.

  Luckily, Clojure comes "with batteries included ready-to-plug-when-needed", so it has these features already available, through clojure.spec and test.check :-)

• Base the aforementioned specifications on the most recent version of the Magic Comprehensive Rules, as published by the Magic copyright holders. As a reference, you will find a copy of the latest version used in /doc/third-party.

• Stand on the shoulders of giants: use Systematic Program Design and (Functional) Domain-Driven Development to strive for achieving a Clean Architecture.

  Systematic Program Design is (greatly!) explained with both depth and simplicity in "How to Design Programs, Second Edition", by Matthias Felleisen, Robert Bruce Findler, Matthew Flatt, and Shriram Krishnamurthi.

  A Functional take on Domain-Driven Development is (excellently!) shown in "Domain Modeling made Functional", by Scott Wlaschin.

  The Clean Architecture is (very entertainingly!) described in "The Clean Architecture", by Robert C. Martin (a.k.a. "Uncle Bob").

This program is inspired by other Magic: The Gathering libre implementations. It's great being able to get inspiration from these great, already-working projects!

Luckily, we have tried them all, read their code, and even made (minor) contributions to some of them.

And we continue to use a couple of them regularly, as each one of them has one thing we appreciate.

More specifically, we are referring to (in discovery order):

As I couldn't find any FP Magic implementation written in Clojure, and given that I want to give clojure.spec a try, I set up to write my own.

Of course, I was not the first one to come up with the idea of using clojure.spec for this. The domain specs are based on Robert Stuttaford's and Adam Frey's work, with their express permission to use their code as I see fit. For more details, see doc/ABOUT_THE_SPECS.md. You will find a copy of the latest Magic Comprehensive Rules document on which the specs are based in the folder /resources/third-party.
