Overview

A Card Mod (short for "module" or "modification") is a discrete piece of Decko functionality. Mods are how the Decko community develops and shares code. If you want to customize a deck in a way that can't be done on the site itself, try a mod.

The simplest way to add a mod is to run this command in your deck:

decko generate card:mod MOD_NAME

This will create the following directories:

DECK_NAME/mod/MOD_NAME
DECK_NAME/mod/MOD_NAME/lib
DECK_NAME/mod/MOD_NAME/public
DECK_NAME/mod/MOD_NAME/set

The lib directory contains libraries, of course. And files in the public directory are public and served directly.

But in most mods, the focal point is the set directory.

Set Modules

Set modules define methods for a given set of cards and their format objects. They are defined in a mod's set directory. For example, suppose you've created a mod that called biz, your deck has Company cards, and you want to extend the behavior of those cards.

You can add a set module like so:

  decko generate set biz type company

This will create the following two files:

  mod/biz/set/type/company.rb
  mod/biz/spec/set/type/company.rb

If you would like to break this code into smaller files, you can extend this pattern into another directory, eg:

  mod/biz/set/type/company/foo.rb
  mod/biz/set/type/company/bar.rb

The general pattern can be expressed as follows:

  DECKNAME/mod/MODNAME/set/SET_PATTERN/ANCHOR[/FREENAME].rb

Other Directories

Other ways your mod can extend Decko functionality include:

format for creating new formats (think file extensions)
set_pattern for additional set patterns, or types of sets.
chunk provides tools for finding new patterns in card content
file for fixed initial card content
