Rusted Iron Ring

Low-level library for exploring From Software games files. Currently only supports Dark Souls 1 (PTDE).

This project is mainly to play with the Rust language, Nom parser, FFI, etc; if you need an actually used and tested library, see SoulsFormats.

Usage

The project contains 2 artefacts:

ironring, a library with all the parsing/unpacking features implemented.
rir, an executable to use main lib features from the CLI.

The goal is to make the lib compatible with FFI tools such as Python's ctypes, to ship a dynamic lib accessible for any language to easily script tasks and ideas, but we're not there yet.

Ironring usage:

Rusted Iron Ring

USAGE:
    rir [SUBCOMMAND]

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

SUBCOMMANDS:
    bhd     Extracts BHD/BDT contents
    bhds    Extracts all BHD/BDT content (alphabetically) in a folder
    bhf     Extracts BHF/BDT contents
    bnd     Extracts BND contents
    dcx     Extracts and decompress DCX data
    hash    Calculates hash for a string
    help    Prints this message or the help of the given subcommand(s)

Features

BHD5 / BDT: extraction from disk to disk.
DCX: decompression from disk to disk/memory.
BND (v3): extraction from disk/memory to disk/memory, optionally decompress from DCX.
BHF (v3): extraction from disk/memory to disk/memory.

Repacking is not supported, maybe one day. It is not that useful when using UDSFM and Yabber, but if you really need it you can check out SiegLib.

There is a demo Python binding for some name_hashes features in the bindings/python dir, that uses PyO3 and thus requires nightly rustc to build.
