Hearthstone Deckstrings

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

Usage

go get github.com/schmich/deckstrings

import "github.com/schmich/deckstrings"

A Hearthstone deckstring encodes a Hearthstone deck in a compact string format. The IDs used in deckstrings and in this library are Hearthstone DBF IDs which are unique identifiers for Hearthstone entities like cards and heroes.

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

See the deckstrings.Deck type for details on how a Hearthstone deck is represented.

Decoding

deckstrings.Decode decodes a deckstring into a Hearthstone deck.

deckstring := "AAECAZICCPIF+Az5DK6rAuC7ApS9AsnHApnTAgtAX/4BxAbkCLS7Asu8As+8At2+AqDNAofOAgA="
deck, err := deckstrings.Decode(deckstring)
fmt.Printf("%+v %v", deck, err)

{Format:2 Heroes:[274] Cards:[[64 2] [95 2] [254 2] [754 1] [836 2] [1124 2] [1656 1] [1657 1] [38318 1] [40372 2] [40416 1] [40523 2] [40527 2] [40596 1] [40797 2] [41929 1] [42656 2] [42759 2] [43417 1]]} <nil>

Encoding

deckstrings.Encode encodes a Hearthstone deck into a deckstring using base64.StdEncoding.

cards := [][2]uint64{
    {9, 1}, {279, 1}, {436, 1}, {545, 2}, {613, 1},
    {1363, 1}, {1367, 1}, {41169, 2}, {41176, 2},
    {42046, 1}, {42597, 2}, {42598, 1}, {42804, 2},
    {42818, 1}, {42992, 2}, {43112, 2}, {46307, 2},
    {46495, 2}, {48002, 1}, {49184, 1}, {49421, 1},
}
deck := Deck{
    Format: deckstrings.FormatStandard, // Standard
    Heroes: []uint64{41887},            // Tyrande Whisperwind
    Cards:  cards,                      // Cards in deck as (DBF ID, count) pairs
}
deckstring, err := deckstrings.Encode(deck)
fmt.Println(deckstring, err)
