# EZPPLauncher
|
||
|
||
**EZPPLauncher** is a custom launcher for the private osu! server [EZPPFarm](https://ez-pp.farm), built with **Rust** and **Svelte** using the [Tauri](https://tauri.app) framework.
|
||
It enhances the osu! experience with quality-of-life features and integration specifically designed for the EZPPFarm community.

## 💻 Supported Platforms
|
||
|
||
| Platform | Status |
|
||
| -------- | ------------------------------------------------------ |
|
||
| Windows | ✅ Supported |
|
||
| macOS | 🕧 Partially supported (via Wineskin/Whisky/CrossOver) |
|
||
| Linux | 🕧 Partially supported (via osu-winello) |
|
||
|
||
> **Windows** remains the fully supported platform. OpenTabletDriver is Windows-only. On macOS,
|
||
> in-game patching runs the Windows patcher through the same Wine prefix as osu!. The stable
|
||
> patcher stream needs no extra runtime; the experimental stream needs the .NET 8 Desktop Runtime
|
||
> installed in that prefix.
|
||
|
||
### macOS
|
||
|
||
osu! stable is a Windows build, so on macOS it runs inside a Wine wrapper. EZPPLauncher
|
||
supports Wineskin wrappers (the usual `osu!.app` wine skin), Whisky bottles and CrossOver
|
||
bottles.
|
||
|
||
The setup wizard automatically looks for Wineskins in `/Applications` and `~/Applications`.
|
||
If detection fails, choose **Browse** and pick the `osu!.app` wrapper itself (or a Wine prefix
|
||
folder); the launcher resolves the osu! installation inside it, so there is no need to open the
|
||
bundle's package contents.
|
||
|
||
Large VP8/VP9/AV1 theme videos are transcoded once to a cached 720p H.264/AAC file so WebKit
|
||
can use the Mac's hardware decoder. The first large video triggers a one-time (~63 MB) download
|
||
of a signed static FFmpeg 9.0.2 build from `ffmpeg.martin-riedl.de` into `~/.ezpplauncher/bin`;
|
||
the launcher verifies its pinned SHA-256 and makes it executable. The managed build requires
|
||
macOS 12 or newer. If the download fails, a system FFmpeg (Homebrew or MacPorts) is used; without
|
||
either, themes still load but large WebM videos remain on WebKit's software decoder and may
|
||
stutter. Theme authors can also ship an H.264/MP4 version alongside the WebM.
|
||

||
## 🪵 Logs
|
||
|
||
Launcher, osu! and patcher output is written to `.ezpplauncher/logs` in your home folder:
|
||
|
||
| File | Contents |
|
||
| -------------- | -------------------------------------------------------------- |
|
||
| `launcher.log` | Launcher lifecycle, webview console output and uncaught errors |
|
||
| `osu.log` | osu! and osu! updater output, including stdout/stderr |
|
||
| `patcher.log` | Patcher output, including stdout/stderr |
|
||
|
||
A file is only created when that stream actually writes a line. On each new session, or when
|
||
any file reaches 5 MiB, all three active files are bundled into a single
|
||
`logs_<date>_<time>.zip`; the five most recent bundles are kept. You can turn file logging off,
|
||
open the folder, or browse and filter a bundle in the built-in viewer from **Settings → Logging**.
|
||
On Windows the folder is `%USERPROFILE%\.ezpplauncher\logs`.
|
||
|
||
**Settings → Diagnostics** checks the selected osu! install and write access, the macOS Wine
|
||
prefix/runtime/version and (for the experimental patcher stream) its .NET 8 runtime, the FFmpeg
|
||
theme-video transcoder, osu-winello/wmctrl on Linux, and whether the patcher is present. It can
|
||
copy a plain-text support report or reopen the setup wizard for a guided repair.

## 🛠 Build From Source
|
||
|
||
### Requirements
|
||
|
||
- **Rust** (installed via [rustup](https://rustup.rs/) – recommended for Windows)
|
||
- **Cargo** (comes with rustup)
|
||
- **[CMake](https://cmake.org/download/)**
|
||
- **[Bun](https://bun.sh/)** (JavaScript runtime)
|
||
- On macOS: **Xcode Command Line Tools** (`xcode-select --install`)
|
||
|
||
### Steps
|
||
|
||
```bash
|
||
# Install all dependencies
|
||
bun i
|
||
|
||
# Build the project
|
||
bun run build
|
||
```
|
||
|
||
After building, the launcher executable will be located at:
|
||
|
||
```
|
||
# Windows
|
||
src-tauri/target/release/ezpplauncher.exe
|
||
|
||
# macOS
|
||
src-tauri/target/release/bundle/macos/EZPPLauncher.app
|
||
src-tauri/target/release/bundle/dmg/EZPPLauncher_*.dmg
|
||
```

## 🎨 Launcher Themes
|
||
|
||
By default, the launcher includes several downloadable themes. Themes can be created
|
||
in two ways:
|
||
|
||
- Use the built-in **advanced editor** on the Themes screen. It opens in its own
|
||
resizable window with a full launcher home canvas, freeform text/image/video/shape
|
||
layers, WebM support, `@fontsource` fonts and custom font imports. It creates API 2.0
|
||
themes and can export them as shareable `.ezpplauncher-theme` files.
|
||
- Use the [create-ezpplauncher-theme](https://git.ez-pp.farm/EZPPFarm/create-ezpplauncher-theme)
|
||
CLI. It supports both API 1.0 Svelte themes and API 2.0 declarative themes.
|
||
|
||
See [THEME_API_V2.md](THEME_API_V2.md) for the full API 2.0 schema, limits and packaging
|
||
layout. API 1.0 themes continue to load unchanged.
