storm-rs

A Rust port of StormLib — a library for reading and writing MPQ (MoPaQ) archives, used by Blizzard Entertainment games.

Features

• Read & Write: Full support for creating, reading, and modifying MPQ archives.
• Compression: Supports ZLIB, PKWARE (Implode), LZMA, Huffman, and ADPCM compression.
• Encryption: Supports file encryption and decryption.
• Patching: Support for incremental patching (BSDIFF40).
• Standard Compliance: Compatible with standard MPQ tools and specifications.

Installation

Add this to your Cargo.toml:

[dependencies]
storm-rs = { git = "https://github.com/phphackerr/storm-rs" }

Usage

Reading an Archive

use storm_rs::MpqArchive;

let archive = MpqArchive::open("archive.mpq")?;
if archive.has_file("file.txt") {
    let content = archive.read_file("file.txt")?;
    println!("Content: {:?}", String::from_utf8_lossy(&content));
}

Creating an Archive

use storm_rs::{MpqArchiveWriter, MpqCreateOptions, AddFileOptions, create_archive};

// Create empty archive
create_archive("new.mpq", &MpqCreateOptions::v1())?;

// Add files
let mut writer = MpqArchiveWriter::open("new.mpq")?;
writer.add_file("hello.txt", b"Hello World", &AddFileOptions::default())?;
writer.finish()?;

Examples

Check the examples/ directory for more comprehensive usage:

• create_archive.rs: Creating archives and adding files.
• read_archive.rs: Reading and extracting files.
• modify_archive.rs: Renaming, deleting, and updating files.
• patch_archive.rs: Applying incremental patches.

Run examples with:

cargo run --example create_archive
