Configuration

Default config location: ~/.config/larpfetch/config.toml

[default]
os = "Arch Linux"
distro = "Arch Linux"
hostname = "btw-i-use-arch"
kernel = "6.99.0-larp"
cpu = "AMD Ryzen 9 9950X3D"
gpu = "NVIDIA RTX 5090"
memory = "128 GiB"
shell = "zsh"

[profiles.custom]
os = "My Custom OS"
cpu = "Custom CPU"
logo = "arch"                    # Reference a built-in logo by name

[profiles.art]
os = "Artistic OS"
logo = """\
    /\\
   /  \\
  /    \\
 /      \\
/________\\
"""                              # Or inline custom ASCII art

[appearance]
color = true
show_authenticity = true
easter_eggs = true
small = true                          # Always use small ASCII art

[display]
fields = ["os", "kernel", "cpu", "memory"]
separator = " -> "
hide_unavailable = true

[display.labels]
memory = "RAM"

Platform-specific config locations

• Linux: $XDG_CONFIG_HOME/larpfetch/config.toml or ~/.config/larpfetch/config.toml
• macOS: ~/Library/Application Support/larpfetch/config.toml
• Windows: %APPDATA%\larpfetch\config.toml

For the full config reference (all fields, appearance options, profiles, inline logos), see docs/CONFIG.md.

Precedence

Normal mode:

CLI overrides > selected profile > default profile > real detected values

Reality mode (--real-shit):

Real values only — bypasses everything

Logos

533 ASCII logos adapted from fastfetch (MIT licensed), with full ANSI color support. Colors are applied automatically and respect NO_COLOR.

Logo selection is based on your displayed identity (or real identity in --real-shit mode). Profiles can override the logo by name or provide custom ASCII art.

Easter Eggs

The output may include occasional humorous lines:

• Authenticity: N% — how much of your output is real
• Source: trust me bro — triggered by implausible memory values
• Reality Leakage: 100.00% — absurdly high package counts
• Disappointment: immeasurable — shown in --real-shit mode
• The allegations were true. — deterministic, based on username hash

Easter eggs are deterministic, disableable via [appearance] easter_eggs = false or LARPFETCH_NO_EASTER_EGGS=1, and not offensive.

Not just a meme

larpfetch is funny on purpose, but it's a real daily-driver fetch tool underneath:

• Detects your actual system with psutil and platform-specific probes
• Clean, aligned, color-aware output that respects NO_COLOR and narrow terminals
• Scriptable: --json, --minimal, --compact, --full, and automatic pipe mode
• Fully customizable: declarative [display] config, named profiles, and CLI overrides
• Cross-platform (Linux, macOS, Windows) with graceful degradation

Reality vs delusion

By default larpfetch shows your LARP identity. --real-shit shows only detected truth. The contrast is the whole point:

Field	Real (--real-shit)	Delusion (-p nasa)
OS	Arch Linux	NASA Linux
CPU	Ryzen 7 7840HS	Quantum Potato 9000
Memory	32 GiB	69 PiB
GPU	Radeon 780M	Classified

--diff-real prints exactly these differences inline, and --show-sources annotates where every value came from:

larpfetch -p nasa --diff-real      # only the fields you're lying about
larpfetch -p nasa --show-sources   # [real] / [default] / [profile] / [cli] per field

The Sacred Rule

The user's delusion is authoritative.

This is valid:

OS: Windows 11 Pro
Kernel: 6.18.7-arch1-1
CPU: Apple M7 Ultra
GPU: NVIDIA RTX 9090 Ti
Memory: 69 PiB
Shell: HolyC
DE: GNOME 83
Package Manager: apt btw

Impossible combinations are accepted. Profiles are display identities, not hardware simulations.

Cross-Platform Support

• Linux: /etc/os-release, lspci, environment variables
• macOS: platform.mac_ver(), system_profiler
• Windows: platform APIs, WMIC, COMSPEC

All platform-specific probes fail gracefully. A missing GPU detector doesn't crash the app.

larpfetch --help                       # Show help

Sharing profiles

Export your real system as a standalone profile, then share the file. Profiles are data-only TOML — loading one never executes code.

larpfetch --export-profile myrig > myrig.toml   # capture your real system
larpfetch --profile-file myrig.toml             # someone else LARPs as your rig
larpfetch --inspect-profile myrig.toml          # see what a profile contains
