Hearthstone Deckstrings

Ruby library for encoding and decoding Hearthstone deckstrings. See documentation for help.

Usage

gem install deckstrings

require 'deckstrings'

Hearthstone deckstrings encode a Hearthstone deck in a compact format.

The IDs used in deckstrings and in this library refer to Hearthstone DBF IDs which uniquely define Hearthstone entities like cards and heroes.

For additional entity metadata (e.g. hero class, card cost, card name), the DBF IDs can be used in conjunction with the HearthstoneJSON database.

Decoding

Deckstrings::decode decodes a deckstring with basic validation.

deckstring = 'AAECAZICCPIF+Az5DK6rAuC7ApS9AsnHApnTAgtAX/4BxAbkCLS7Asu8As+8At2+AqDNAofOAgA='
puts Deckstrings::decode(deckstring)

{:format=>2, :heroes=>[274], :cards=>{754=>1, 1656=>1, 1657=>1, 38318=>1, 40416=>1, 40596=>1, 41929=>1, 43417=>1, 64=>2, 95=>2, 254=>2, 836=>2, 1124=>2, 40372=>2, 40523=>2, 40527=>2, 40797=>2, 42656=>2, 42759=>2}}

Deckstrings::Deck.decode decodes a deckstring with extended validation and additional deck information including card names and costs.

deckstring = 'AAECAZICCPIF+Az5DK6rAuC7ApS9AsnHApnTAgtAX/4BxAbkCLS7Asu8As+8At2+AqDNAofOAgA='
puts Deckstrings::Deck.decode(deckstring)
