Dependencies
============

Windows
--------

On Windows, it's **highly recommended** to use native tooling. WSL or msys2 are **not** required.
When running under WSL, [objdiff](#diffing) is unable to get filesystem notifications for automatic rebuilds.

- Install [Python](https://www.python.org/downloads/) and add it to `%PATH%`.
- Also available from the [Windows Store](https://apps.microsoft.com/store/detail/python-311/9NRWMJP3717K).
- Download [ninja](https://github.com/ninja-build/ninja/releases) and add it to `%PATH%`.
- Quick install via pip: `pip install ninja`

macOS
------

- Install [ninja](https://github.com/ninja-build/ninja/wiki/Pre-built-Ninja-packages):

```sh
brew install ninja
```

- Install [wine-crossover](https://github.com/Gcenx/homebrew-wine):

```sh
brew install --cask --no-quarantine gcenx/wine/wine-crossover
```

After OS upgrades, if macOS complains about `Wine Crossover.app` being unverified, you can unquarantine it using:

```sh
sudo xattr -rd com.apple.quarantine '/Applications/Wine Crossover.app'
```

Linux
------

- Install [ninja](https://github.com/ninja-build/ninja/wiki/Pre-built-Ninja-packages).
- For non-x86(_64) platforms: Install wine from your package manager.
- For x86(_64), [wibo](https://github.com/decompals/wibo), a minimal 32-bit Windows binary wrapper, will be automatically downloaded and used.

Building
========

- Clone the repository:

```sh
git clone https://github.com/zeldaret/tp.git
```

- Copy your game's disc image to `orig/GZ2E01`.
- Supported formats: ISO (GCM), RVZ, WIA, WBFS, CISO, NFS, GCZ, TGC.
- After the initial build, the disc image can be deleted to save space.

- Configure:

```sh
python configure.py
```

To use a version other than `GZ2E01` (USA), specify it with `--version`.
- Build:

```sh
ninja
```

Diffing
=======

Once the initial build succeeds, an `objdiff.json` should exist in the project root.

Download the latest release from [encounter/objdiff](https://github.com/encounter/objdiff). Under project settings, set `Project directory`. The configuration should be loaded automatically.

Select an object from the left sidebar to begin diffing. Changes to the project will rebuild automatically: changes to source files, headers, `configure.py`, `splits.txt` or `symbols.txt`.
