cards-52-encoder

Encodes and decodes playing cards of a 52 card deck

const sixbit = require('6bit-encoder')
const { cardsEncoder } = require('../')
const cards = [ '2d', '5c', 'Js', '8h', 'Ad' ]

const encoder = cardsEncoder(5)
const encodedBits = encoder.encode(cards)
const encoded = sixbit.encode5(encodedBits)
const decodedChars = sixbit.decode5(encoded)
const decoded = encoder.decode(decodedChars)

console.log({ encoded, decoded })

// => { encoded: '2OFbo', decoded: [ '2d', '5c', 'Js', '8h', 'Ad' ] }

Installation

npm install cards-52-encoder

API

cardEncoder

Creates a encoder that encodes/decodes one card.

Parameters

• idx Number? index in the bits at which the encoded card is located (optional, default 0)

Returns CardEncoder a card encoder with encode(String card) and decode(Number bits) methods

cardsEncoder

Creates a encoder that encodes/decodes a specific number of cards.

Parameters

• n Number the number of cards to encode/decode
• idx Number? index in the bits at which the encoded cards are located (optional, default 0)

Returns CardsEncoder a card encoder with encode(String cards) and decode(Number bits) methods

CARD_NOT_PRESENT

A 2 char string indicating a non present card as '??'.

Type: String

CardEncoder.encode

Encodes a card.

The idx is taken into account so that an | operation allows including the encoded information into existing bits.

Parameters

• card String the card to encode

Returns Number the bits representing that card

CardEncoder.decode

Decodes a card.

The idx is taken into account so that the card can be decoded from within anywhere inside the given bits.

Parameters

• allBits Number the bits in which a card is encoded

Returns String the decoded card

CardsEncoder.encode

Encodes a number of cards.

The idx is taken into account so that an | operation allows including the encoded information into existing bits.

Parameters

• cards Array<String> the cards to encode

Returns Number the bits representing the cards

CardsEncoder.decode

Encodes a number of cards.

The idx is taken into account so that an | operation allows including the encoded information into existing bits.

Parameters

• allBits Number the bits in which the cards are encoded

Returns Array<String> the decoded cards
