# YALI (Yet Another Linux Installer) — Rust / egui

A rewritten **Pisi GNU/Linux** installation tool in Rust and egui. YALI installs the system from the live environment, installs packages, and performs basic configuration. It is a modern, fast, and maintainable rewrite of the original Python/Qt version.

## Features

- **10-step installation wizard**: Welcome → Location → Keyboard → Network → Disk Partitioning → Users → Bootloader → Summary → Installation → Finish
- **Two modes**: Graphical interface (default) and automatic installation with answer file (`--auto-install answer.toml`)
- **Demo mode**: Skips system checks, simulates installation (`--demo`)
- **Disk partitioning**: Automatic (GPT/MBR) or manual, LVM and LUKS encryption support
- **Network configuration**: WiFi scanning (nmcli), proxy settings
- **Bootloader**: GRUB device/password/timeout settings, kernel parameters
- **Rescue mode**: Chroot, GRUB reinstallation, Pisi rollback
- **OEM mode**: Predefined settings for manufacturer pre-installation
- **Internationalization**: Turkish and English (with rust-i18n via TOML locale files)
- **Branding system**: Runtime-loadable `branding.toml` for logo, slides, color settings
- **Theme**: Dark/light theme, atomic color management, custom gradient buttons
- **Async job queue**: All installation steps run in separate `tokio` runtime, UI updated via `mpsc` channel
- **System checks**: 8 pre-checks including RAM, disk space, internet, UEFI, CPU, NVMe
- **Slideshow**: Custom branded slides for 9 desktop environments
- **Demo session cleanup**: Removes live environment artifacts, adds production repository

## Usage

```bash
# Normal installation (requires root)
sudo cargo run --release

# Demo mode (no root required)
cargo run --release -- --demo

# Automatic installation (with answer file)
sudo cargo run --release -- --auto-install answer.toml
```

## Installation Workflow

1. **Welcome** — Language selection, system checks, rescue mode
2. **Location / Time** — Timezone selection (region/area dual ComboBox), GeoIP, NTP or manual date/time
3. **Keyboard** — Layout/variant selection, search, live preview (setxkbmap)
4. **Network** — WiFi scanning, connection, proxy
5. **Disk Partitioning** — Automatic (guided) or manual, LVM, LUKS
6. **Users** — Account creation, password strength indicator, root password, autologin
7. **Bootloader** — GRUB device, timeout, password, kernel parameters
8. **Summary** — Review all selections
9. **Installation** — Slideshow + progress bar + live log
10. **Finish** — Successful installation, reboot or return to live desktop
