📦 Installation

Install on Arch Linux (via AUR)

If you're on Arch Linux or an Arch-based distribution (like Manjaro), you can install LeenFetch from the AUR using an AUR helper like yay:

yay -S leenfetch

or

git clone https://aur.archlinux.org/leenfetch.git
cd leenfetch
makepkg -si

Install on Debian / Ubuntu (via .deb)

If you're on Debian, Ubuntu, or a Debian-based distribution, you can download and install the .deb package from the GitHub Releases:

  • AMD64 (x86_64)
wget https://github.com/drunkleen/leenfetch/releases/download/v0.2.1/leenfetch-v0.2.1-debian-x86_64.deb
sudo dpkg -i leenfetch-*.deb
  • AArch64 (ARM64)
wget https://github.com/drunkleen/leenfetch/releases/download/v0.2.1/leenfetch-v0.2.1-debian-aarch64.deb
sudo dpkg -i leenfetch-*.deb

Install on Fedora / RHEL (via .rpm)

If you're using Fedora, RHEL, or another RPM-based distro, you can install LeenFetch using the .rpm file from GitHub Releases:

  • AMD64 (x86_64)
wget https://github.com/drunkleen/leenfetch/releases/download/v0.2.1/leenfetch-v0.2.1-REHL-x86_64.rpm
sudo rpm -i leenfetch-*.rpm

Install on Windows (via .zip)

If you're on Windows, download the latest .zip from the GitHub Releases:

powershell:

  • AMD64 (x86_64)
Invoke-WebRequest -Uri "https://github.com/drunkleen/leenfetch/releases/download/v0.2.1/leenfetch-v0.2.1-windows-x86_64.zip" -OutFile "leenfetch-win.zip"
Expand-Archive .\leenfetch-win.zip -DestinationPath .

.\leenfetch-v0.2.1-windows-x86_64.exe

Make sure you're in the same directory as leenfetch.exe when running the command.

Install from crates.io

Make sure you have Rust & Cargo installed:

cargo install leenfetch

After that, just run:

leenfetch

If you hit issues with PATH, try adding ~/.cargo/bin to your shell:

export PATH="$HOME/.cargo/bin:$PATH"

🛠️ Manual Installation (Build from Source)

git clone https://github.com/drunkleen/leenfetch.git
cd leenfetch
cargo build --release

Add to PATH:

cp target/release/leenfetch ~/.local/bin/

Then run:

leenfetch

📥 Using Piped Input

LeenFetch can accept piped input to use as the ASCII logo.

This allows you to create dynamic, fun logos on the fly using other command-line tools.

Examples:

echo "Rustacean" | leenfetch

fortune | cowsay | leenfetch

LeenFetch will detect piped input via stdin and render the ASCII art above your system information.

If no piped input is provided, it will fall back to your configured or auto-detected ASCII art.

⚙️ Configuration

On first run, LeenFetch will generate three config files in:

# Linux
~/.config/leenfetch/

# Windows
C:\Users\<username>\AppData\Roaming\leenfetch\
  • flags.ron — Controls display and formatting options for each block.
  • toggles.ron — Controls which information blocks are shown or hidden.
  • print_layout.ron — Controls the order and labels of blocks in the output.

Each file is heavily commented, so you can read the file itself for a full explanation of every option.

flags.ron

This file lets you fine-tune how each block of information is displayed. You can:

  • Choose which ASCII art and color palette to use.
  • Select how battery, disk, memory, and package info are shown.
  • Pick units, detail level, and formatting for each section.
  • Enable or disable features like CPU brand, temperature, shell version, etc.

If input is piped into leenfetch, the ASCII logo from ascii_distro or custom_ascii_path is ignored and the piped content is used instead.

Example:

(
    // Select which distribution's ASCII art to display at the top.
    // Options:
    //   "auto"   - Automatically detect and use your current distribution's ASCII art.
    //   <name>   - Use a specific distro's art (e.g., "arch", "ubuntu", "debian").
    ascii_distro: "auto",
    ...
)

toggles.ron

This file controls which blocks of information are shown in the output. Set each option to true to show that block, or false to hide it.

Example:

(
    // Show the user@host title at the top of the output.
    // true  - Display the title block (e.g., "snape@archbox").
    // false - Hide the title block.
    show_titles: true,
    ...
)

print_layout.ron

This file controls the order and labels of each block in the output. You can rearrange, remove, or relabel any section to customize your output.

Example:

[
    // The user@host title block (e.g., "snape@archbox").
    (label: "Titles", field: "titles"),
    // The distribution (distro) information (e.g., "Arch Linux").
    (label: "Distro", field: "distro"),
    ...
]

How to Edit

  • Open any of the .ron files in your favorite text editor.
  • Read the comments above each option for a full explanation.
  • Change values as you like, save, and re-run leenfetch to see your changes.

For advanced details, see the comments in each config file or check the wiki (if available).
