Description

This package contains a Diablo II save files (D2S) decoder and encoder written in golang

Dependencies / Documentation

D2S structure documentation:

• krisives/d2s-format
• Diablo II Saved Game File Format
• nokka/d2s (see details)
• pairofdocs/d2s_edit_recalc

I depend on

This project uses Data stream writer based on these used in OpenDiablo2 project for more informations, see here

Status

for now (May 2021) the project is early in development. However, it is possible to:

• decode character save file into a (in a greater part) human-readable structure
• encoding file

Example

for some reasons, this project isn't able to create a whole new file yet, but it is able to load modify and than encode D2S format

simple example

package main

import (
        "fmt"
        "ioutil"
        "log"

        "github.com/gucio321/d2d2s/pkg/d2s"
)

func main() {
        data, err := ioutil.ReadFile("/path/to/file.d2s")
        if err != nil {
                log.Fatal(err)
        }

        character, err := d2s.Unmarshal(data)
        if err != nil {
                log.Fatal(err)
        }

        // some edits

        newData, err := d2d2s.Encode(character)
        if err != nil {
                log.fatal(err)
        }

        if err := ioutil.WriteFile("/path/to/new/file.d2s", newData, 0o600); err != nil {
                log.Fatal("error writing file")
        }
}

Goals of the project

this programm should be able to decode, encode and create a new D2S files

Custom D2S Files

Sometimes, you may want to parse some custom d2s files. For example these created by certain d2 mods. They are not supported by default, however you can do some configuration to support them.

NOTE: add this code in your custom implementation of package or modify cmd/editor
