pfetch-rs

A rewrite of the pfetch system information tool by dylanaraps in Rust

About

If you are familiar with the pfetch system information tool by dylanaraps, this does the exact same thing, but with an about 10x faster runtime. pfetch is simple by design with some (but not many) configuration options and a minimalistic look.

Supported Platforms: Linux, Android, DragonflyBSD, FreeBSD, NetBSD, OpenBSD, WSL, Haiku, MacOS, Minix, Solaris, IRIX, SerenityOS

Disclaimer: Aside from Linux, all of these platforms are untested. If you run into problems, please open an issue.

Included Logos: Alpine Linux, Android, Arch Linux, ArcoLinux, Artix Linux, Bedrock Linux, Buildroot, CelOS, CentOS, Crystal Linux, dahliaOS, Debian, Devuan, DragonflyBSD, Elementary OS, EndeavourOS, Fedora, FreeBSD, Garuda Linux, Gentoo Linux, Gnu, Guix, Haiku, HydroOS, Hyperbola, instantOS, IRIX, KDE neon, Linux Lite, Linux, Mint, macOS, Mageia, Manjaro, Minix, MX Linux, NetBSD, NixOS, OpenBSD, openSUSE Tumbleweed, openSUSE Leap, OpenWrt, Parabola, Pop!_OS (updated), PureOS, Raspbian, SerenityOS, Slackware, Solus, Solaris, Ubuntu, Void Linux, Xeonix Linux, Fiwix (new), MorphOS (new), AmogOS (new), Aperio (new)

For all other distributions, a penguin will be displayed.

Status

This project is still in early development, expect things to not work properly. Please open issues for bugs you are encountering.

Installation

Cargo

sh cargo install pfetch

AUR

Install the pfetch-rs AUR package

Performance

Benchmarks performed on an AMD Ryzen 5 3600. Execution time is measured using hyperfine with -w 4 -m 500 -N flags

| Implementation | Mean [ms] | Min [ms] | Max [ms] | | :---------------: | :--------: | :------: | :------: | | POSIX sh (bash) | 27.3 ± 0.9 | 25.3 | 23.2 | | POSIX sh (dash) | 19.3 ± 0.6 | 18.3 | 24.0 | | Rust | 2.1 ± 0.2 | 1.8 | 3.6 |

Note: This is with pacman being the only installed package manager. Especially having nix installed will have a big impact on performance, as querying installed nix packages is very costly.

Configuration

Like the original pfetch, pfetch-rs is configured through environment variables. Your existing config will probably still work, the only difference is how padding is configured.

If you want to display a custom logo, you will have to download the source code, make your changes to ./pfetch-extractor/logos.sh and build the binary with cargo b --release.
