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, macOS, Windows, FreeBSD, NetBSD

You can check out how they look here.

For all other distributions, a penguin will be displayed.

If you want a logo to be added, feel free to open an issue or a PR.

Installation

Note: On openSUSE, install the rpm-devel package for faster package count.

Binary

Download a binary from the latest release.

Cargo

cargo install pfetch

Homebrew

brew install pfetch-rs

Nixpkgs

Install the pfetch-rs Nix package.

AUR

Install the pfetch-rs or pfetch-rs-bin AUR package.

Performance

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

Note: This is with pacman and flatpak being the only installed package managers. For more info, see Improving Performance.

Improving Performance

The by far slowest part of the pfetch execution time is counting the installed packages. For most package managers this is still very fast, but there are some (currently nix (and zypper, if rpm-devel is not installed)) that take ~500ms to report installed packages, which takes away all performance benefits of the Rust version. If you have one or more of these installed, you can skip counting them by setting the PF_FAST_PKG_COUNT environment variable to any value.

Configuration

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

If you want to display a custom logo, use the PF_CUSTOM_LOGOS option, an example for a custom logos file can be found below.

# Which information to display.
# Default: first example below
# Valid: space separated string
#
# OFF by default: shell editor wm de palette cpu
PF_INFO="ascii title os host kernel uptime pkgs memory"

# Example: Only ASCII.
PF_INFO="ascii"

# Example: Only Information.
PF_INFO="title os host kernel uptime pkgs memory"

# A file containing environment variables to source before running pfetch
# Default: unset
# Valid: A shell script
PF_SOURCE=""

# A file containing pfetch logos to overwrite default logos or add new logos
# Default: unset
# Valid: Path to a file containing pfetch logos (example below)
PF_CUSTOM_LOGOS="~/.config/pfetch_logos"

# Separator between info name and info data.
# Default: unset
# Valid: string
PF_SEP=":"

# Enable/Disable colors in output:
# Default: 1
# Valid: 1 (enabled), 0 (disabled)
PF_COLOR=1

# Color of info names:
# Default: unset (auto)
# Valid: 0-9
PF_COL1=4

# Color of info data:
# Default: unset (auto)
# Valid: 0-9
PF_COL2=9

# Color of title data:
# Default: unset (auto)
# Valid: 0-9, COL1 (copies COL1 value)
PF_COL3=1

# Alignment paddings (this is different to the original version).
# Default: unset (auto)
# Valid: int
PF_PAD1=""
PF_PAD2=""
PF_PAD3=""

# Which ascii art to use.
# Default: unset (auto)
# Valid: string
PF_ASCII="openbsd"

# The below environment variables control more
# than just 'pfetch' and can be passed using
# 'HOSTNAME=cool_pc pfetch' to restrict their
# usage solely to 'pfetch'.

# Which user to display.
USER=""

# Which hostname to display.
HOSTNAME=""

# Skip package managers that take "long" to query package count (like nix)
PF_FAST_PKG_COUNT=1

A file containing custom pfetch logos could look like this (also found under custom_logos_example). This will turn the Arch Linux logo red, the Debian Logo blue and the Fedora logo yellow:

[Aa]rch*)
	read_ascii 1 <<- EOF
			${c1}       /\\
			${c1}      /  \\
			${c1}     /\\   \\
			${c1}    /      \\
			${c1}   /   ,,   \\
			${c1}  /   |  |  -\\
			${c1} /_-''    ''-_\\
		EOF
	;;
[Dd]ebian*)
	read_ascii 4 <<- EOF
			${c4}  _____
			${c4} /  __ \\
			${c4}|  /    |
			${c4}|  \\___-
			${c4}-_
			${c4}  --_
		EOF
	;;
[Ff]edora*)
    read_ascii 3 <<- EOF
			        ${c3},'''''.
			       ${c3}|   ,.  |
			       ${c3}|  |  '_'
			${c3}  ,....|  |..
			${c3}.'  ,_;|   ..'
			${c3}|  |   |  |
			${c3}|  ',_,'  |
			${c3} '.     ,'
			   ${c3}'''''
		EOF

Note: Make sure to use tabs for indentation and separate logos with ;;, as seen above. You only need to add the logos you want to overwrite/add, the default logos will stay available. The included logos can be found at ./pfetch-extractor/logos.sh.
