glamfetch

A glamorous system-info fetch tool for the terminal. Alternative to fastfetch / neofetch for rice enthusiasts who want full styling control without sacrificing speed.

Status: post-v0.1.0, Phase 6 complete on master. See .docs/glamfetch-spec.md for the full v1 spec and phase roadmap. The v0.2.0 launch is the version that goes on r/unixporn.

Install

From source:

git clone https://github.com/synnode/glamfetch
cd glamfetch
cargo install --path .

Requires Rust 1.85+.

Run

glamfetch                  # render default preset
glamfetch --pipe           # plain output, no ANSI
glamfetch --json           # all collector data as JSON for jq / scripting
glamfetch --print-data     # human-readable dump of available ${data.*} refs
glamfetch --print-config   # resolved config
glamfetch --init           # write default preset to ~/.config/glamfetch/config.toml
glamfetch --list-presets

Configure

Default config path (XDG): ~/.config/glamfetch/config.toml.

[theme]
accent     = "#cba6f7"
muted      = "#6c7086"
bar_filled = "${theme.accent}"

[[row]]
gap = 2

[[row.cell]]
widget = "box"
title  = "system"
title_color = "${theme.accent}"
border = "rounded"
padding = [0, 1]
child = { widget = "text", content = """
  host    ${data.system.hostname}
  os      ${data.os.name}
  kernel  ${data.kernel.version}
""" }

See .docs/glamfetch-spec.md §6 for the full schema, §7 for collector field listings, §8 for widget reference.

Scope

What's in (master, post-v0.1.0):

• Collectors: system, os, kernel, uptime, cpu, mem, disk, gpu, battery, network, packages, desktop, datetime
• Widgets: text, stack, row (inner), box, gauge, bar, spacer, separator, figlet, ascii
• Box borders: rounded, sharp, double, thick, ascii
• Figlet fonts: 11 embedded (standard, slant, small, big, ansi_shadow, shadow, block, mini, lean, script, banner) plus any .flf via filesystem path
• Themes with ${theme.*} variable resolution + cycle detection
• Per-character gradient colors on any colored widget (color = { gradient = ["#ff8800", "${theme.accent}"] })
• Filters: humanize, round, truncate, upper/lower/title, pad, default
• show_if conditional rendering (JSON-truthy semantics)
• extends = "<preset|path>" config inheritance (string or array, CSS-cascade order, deep merge)
• Built-in presets: default, catppuccin, gruvbox, nord (--list-presets)
• True-color ANSI + 256-color quantizer fallback
• --pipe, --json, --print-data, NO_COLOR, non-TTY auto-detect
• --watch [INTERVAL] — interval re-render in alt-screen, q / Esc / Ctrl+C to exit
• --edit — live preview pane; re-renders on config save via notify, parse errors render in place. Pair with tmux/zellij for split view.
• Parallel collector execution via rayon
• Collector pre-pass: only collectors referenced by the layout actually run

Coming in v0.2.0:

• Polished launch (screenshots, man page, AUR PKGBUILD)

Performance

Measured on an Intel i7-13700K, release build (LTO + strip), Linux:

Command	Time
glamfetch --version (cold start)	1-2ms
glamfetch --pipe, default preset (CPU + RAM gauges)	60-61ms
glamfetch --pipe, minimal preset (no CPU usage)	7ms
glamfetch --json (runs every collector)	60ms
Binary size (release, stripped)	2.8 MB

Two things are doing the heavy lifting here:

• Collector pre-pass. Before priming the registry the binary scans the config for ${data.<root>} references and only runs collectors actually named. A preset that doesn't reference ${data.cpu.usage} skips the 50ms sample window automatically.
• Parallel collection. Referenced collectors run on a rayon thread pool, so the heaviest config still bottlenecks on its single slowest collector (the CPU sample) instead of summing them.
