Duey.Provider.WZ 2.0.0

Duey

A minimal read-only implementation of the PKG1.0 and NX PKG4.1 format file specification on .NET Standard 2.1

🤔 Why?

• Duey works on runtimes targeting or supporting .NET Standard!
• also, it's strictly parsing only. no caches, no weird voodoo magic.

🏹 Supported Types

✏️ Usage (PKG4.1)

to get started, simply create a new NX Package object like so.

var pkg = new NXPackage("Data.nx");

with that, you can do various parsing magic!

// store a node object for usage later on!
var node = pkg.ResolvePath("Store/Products");

// resolve to a nullable
var name = node.ResolveString("name");
var image = node.ResolveBitmap("image");
var soundFx = node.ResolveAudio("soundFx");

// resolve a node ..in a node!
var bundles = node.ResolvePath("Bundled Products");

foreach (var bundle in bundles)
{
    // resolve even more stuff here!
}

// all the previous resolving examples run at O(n)
// if efficiency and speed is an issue..
// this eager loads direct child of the selected node.
var resolution = node.ResolveAll(); // O(n)

name = resolution.ResolveString("name"); // O(1)
stock = resolution.ResolveInt("stock") ?? 0; // O(1)
price = resolution.ResolveDouble("price") ?? 0.0; // O(1)

// compared to..
name = node.ResolveString("name"); // O(n)
stock = node.ResolveInt("stock") ?? 0; // O(n)
price = node.ResolveDouble("price") ?? 0.0; // O(n)

parsing bitmaps/images with ImageSharp

var bitmap = node.ResolveBitmap("icon");

using (var image = Image.LoadPixelData<Bgra32>(bitmap.Data, bitmap.Width, bitmap.Height))
using (var output = File.Create("icon.png")) {
    // do image manipulation stuff here
    // save the image!
    image.SaveAsPng(output);
}

📖 Usage (PKG1.0)

to get started, simply create a new WZ Package object like so. Do note that a key is required to decode properly.

var pkg = new WZPackage("Data.wz", "95");

Alternate filesystem and .img file loading

var pkg = new FSDirectory("./Data/");

All resolve methods are synchronous with the PKG4.1 examples.
