# alertify
*uwu nya*

> **alertify** is a lightweight and efficient system notification tool written in Rust. It monitors system events like battery status, memory usage, device connections, and more, and sends desktop notifications to keep you informed in real time.

---

## Features

- Battery level monitoring with alerts
- CPU, memory and storage usage notifications
- Device connection and disconnection events (via udev)
- Monitoring of power supply status changing
- Configurable via a TOML configuration file
- Built with modern Rust async ecosystem (Tokio, Zbus, etc.)

---

## Installation

### From AUR

```bash
yay -S alertify
```

### From source

You can build **alertify** from source using Cargo:

```bash
git clone https://github.com/arebaka/alertify.git
cd alertify
cargo build --release
```
## Configuration

`alertify` is configured via a single `config.toml` file. It defines a list of notification rules for system events like battery level, memory usage, disk space, device connections, and power supply status.

The file is loaded from:

1. `$XDG_CONFIG_HOME/alertify/config.toml`
2. `~/.config/alertify/config.toml`

### Example configuration

```toml
[[battery]]
level = 20
urgency = "critical"
appname = ""
summary = "Low Battery"
body = "Battery level dropped to {left_percent}%!"
icon = "battery-caution-symbolic"

[[battery]]
level = 5
urgency = "critical"
appname = ""
summary = "Critical Battery Level"
body = "Battery level dropped to {left_percent}%!"

appname = ""
summary = "Power cable disconnected"
body = ""
icon = "ac-adapter-symbolic"
hints = ["transient", "category:power-supply", "string:x-dunst-stack-tag:power-supply"]
```

### Supported sections

Each section type corresponds to a system resource or event and accepts multiple entries:

- `[[battery]]`: Notifications for low battery levels
- `[[cpu]]`: CPU usage alerts
- `[[memory]]`: RAM usage alerts
- `[[storage]]`: Low disk space warnings
- `[[device]]`: USB or other device events (via udev)
- `[[power_supply]]`: AC adapter plugged/unplugged events
