Deckard is a simple deck shuffeling and card drawing program, its designed to use deck definition files (written as a JSON object filled with only named arrays. Its also named after Deckard from do androids dream of electric sheep by Isacc Asimov.

An example of a deck definition file:

{
"value":[ "A", "2", "3", "4", "5", "6", "7", "8", "9", "10", "J", "Q", "K"],
"suit":[ "♥", "♣", "♠", "♦"]
}

Using this you can make all kinds of decks.

A more advanced example uses an array of "decks" to build a single deck.

[{
"value":["A","2","3","4","5","6","7","8","9","10","J","Q","K"],
"shape":["♥","♣","♠","♦"]
},{
"color":["red ", "black "],
"joker":["joker"]
}]
