pumo-system-info is designed to retrieve detailed information about connected Bluetooth devices and present it in a structured JSON format. This utility can be integrated with other tools or scripts for system monitoring and management. In particular, this tool is meant to be used with my eww configuration.

Prerequisites

DBus
BlueZ (for retrieving Bluetooth-related information)
UPower (for retrieving power information)
Rust (specified in rustup-toolchain.toml)
Nix package manager with flakes (optional, for building and managing dependencies)

Installation

Clone the repository

git clone https://labs.phundrak.com/phundrak/pumo-system-info.git
cd pumo-system-info

Build the project

With Nix
```
nix build
./result/bin/pumo-system-info
```

Without Nix

cargo build --release
./target/release/pumo-system-info

Performance

Since this is a utility for bringing information to eww, this project needs to run fast. Fortunately, it does! Here are some benchmarks I ran on the computers I can run it on. The results are obtained through hyperfine.

cargo build --release
hyperfine --warmup 3 -N ./target/release/pumo-system-info
