Hayabusa is a swift rust fetch program.

When configured for speed it boasts an internal runtime of under 2ms. Despite its speed, this is a fully featured fetch, unlike many of its brethren. It is also extremely configurable, enabling near infinite customization. The level of customization is from the fact that the config file is a lua script in the users config directory. The program is split into a user facing binary and a system service daemon. The daemon is responsible for gathering the system information ahead of time and having it prepared for the user facing binary. This binary then injects said system information into the lua script and extracts the result. While the ascii art is embedded in the binary, configuration allows for specifying a path to a file containing the ascii art. Not only this, but hayabusa has image support, it can display any png file as long as the terminal supports it.

Installation

This program is packaged firstly as a nix package available through the flakes outputs. Furthermore there is a nixosModule provided, simply add hayabusa.nixosModules.default to your modules, then set services.hayabusa.enable to true. Ensure you add the package provided by the flake to your PATH. If you do not use NixOS, I have decided to not deal with packaging it myself. There are an unreal amount of package managers, and frankly literally anyone can package it for a package manager and make it avilable to everyone. If you really want hayabusa, and there exists no package for you, the binary and the service file are in releases. Feel free to deploy it yourself.

If you really can't do that, and still want to use hayabusa, the below solution exists at your own risk. I recommend against using it, as every operating system is wildly different, and there is no guarantee it will not break something.

• Download install-linux.sh from releases.
• Run it in the terminal.

Finished! You can now run hayabusa to run the program.

Usage

You will need to have the daemon running in the background before making a request with the user facing binary. It is recommended to use a systemd service to manage the daemon.
