bfree 0.1.1

A better free, human by default
Documentation

bfree โœจ

A better free, human by default. Inspired by tools like btop, bfree gives you memory and swap stats in a clean one-line summary.

The command nobody asked for โ€” but your RAM deserves it. ๐Ÿš€

Why bfree?

The traditional free command is powerful but outdated in UX and modern workload awareness.

Problems with free

  • โŒ Not human-readable by default (KB output)
  • โŒ Confusing memory semantics (used vs free vs buff/cache)
  • โŒ No percentages
  • โŒ No visual signal
  • โŒ Not container/cgroup aware
  • โŒ No context about reclaimable memory
  • โŒ No PSI (pressure stall info)
  • โŒ Misleading inside Kubernetes / Docker / Podman

Modern systems deserve better visibility.

Highlights

  • ๐Ÿงผ Clean by design โ€” minimal, focused, and pleasant to read
  • ๐Ÿ“Š Human-first output โ€” sizes + percentages in one line
  • ๐Ÿง  Useful memory semantics โ€” includes effective reclaimable cache
  • โšก Snappy โ€” lightweight Rust CLI

Status

  • โœ… Linux /proc/meminfo parser
  • โœ… One-line memory + swap output
  • โœ… Percentages for used/cache/available/swap
  • โœ… Unit tests for memory math
  • ๐Ÿ”œ Container/cgroup-aware mode
  • ๐Ÿ”œ PSI (pressure stall information)
  • ๐Ÿ”œ Optional visual signal (bars/colors)

Current Semantics

  • used = MemTotal - MemAvailable
  • cache = Cached + SReclaimable - Shmem (effective reclaimable cache)
  • avail = MemAvailable
