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][soulsformats].

Usage
-----

The project contains 2 artefacts:

- `librir`, a library containing all the parsing/unpacking features implemented.
- `ironring`, 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:

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