Rusted Iron Ring
================
Low-level library for exploring From Software games files.
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].
The main target has been Dark Souls 1 PTDE, but checkout the features section
below.

Usage
-----
The project contains 2 artefacts:
- `ironring`, a library with all the projects features implemented.
- `rir`, an executable to use main lib features from the CLI.
```

Features
--------
### Format support
| Type | Games | Features |
|----------|-------|------------------------------------------|
| BHD5/BDT | DS1 | Load, extract |
| DCX | DS1 | Load, extract |
| BND3 | DS1 | Load, extract |
| BHF3 | DS1 | Load, extract |
| DAT | KF4 | Load, extract, repack |
| PARAMDEF | DS1 | Pretty-print |
| PARAM | DS1 | Pretty-print, optionally with a PARAMDEF |
Formats typically found within DCX files can usually be decompressed on the fly.
Repacking is mostly 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].

[sieglib]: https://github.com/Dece/DarkSoulsDev/tree/master/Programs/SiegLib
### Misc
- Encrypted archive name hasher.
- There is a demo Python binding for some `name_hashes` features in the
`bindings/python` dir, that uses [PyO3][pyo3] and thus requires nightly
rustc to build.
