xeon 634fef8b12 printOutput: fix string formatting for utsname fields 
The Io.Writer.print function supports unsized, "many-item" pointers with
sentinel. However, it to ignores the sentinel due to the fact that
the passed pointer has its length encoded in the type itself (for
example: `*const [64:0]u8`), therefore it ended up outputting all 64 bytes,
which may display garbage in case if these bytes are in fact not zeroed.
The solution is to cast array pointer to a `[*:0]const u8`, which is an
unsized equivalent. The formatting function will then acknowledge the
sentinel internally.

refetch

a no-nonsense, simple and minimal system information fetching tool for Linux-based systems. screenshot

What

refetch is ~400 lines of idiomatic Zig that is:

  • simple, portable, coherent
  • tiny: the binary is smaller than most tools, including microfetch's Cargo.lock
  • fast, I guess

Why?

The state of fetch tools is an embarrassment.

  • Fastfetch is a bloated, enterprise-grade monument to C++ism.
  • Microfetch is a case study in Engineering Misalignment. It's 5000 lines of deranged, unidiomatic Rust.
  • 0fetch is an assembly mess; claiming x86_64 is the only "actual architecture" is a pure delusion - it's the Windows of ISAs. Writing unportable code doesn't make you elite, it just makes your tool useless.

Nerd Fonts are wasting your time and mine.

Why the fuck are you loading 20MB of "Nerd Fonts" just to render a folder icon and some system uptime? Are you even going to notice that it's not some special glyph? Why do you even bother when it just turns your terminal into a cluttered mess of low-res icons? Stop fucking around with font-patching scripts and use the charset your terminal already has.

Performance

Measured with hyperfine.

Command Mean [µs] Min [µs] Max [µs] Relative
refetch 169.9 ± 45.2 36.9 265.0 1.17 ± 0.47
fastfetch 6846.4 ± 220.1 6286.6 7483.6 47.01 ± 14.38
microfetch 403.0 ± 43.4 238.1 504.7 2.77 ± 0.89
0fetch 145.6 ± 44.3 25.2 247.8 1.00

Installation

The only requirement is a zig compiler.

  • NOTE: in case you don't happen to have one, you can use the envrc shell script included in this repository. No need for an esoteric functional language to obtain a single binary.
zig build -Doptimize=ReleaseSmall

This is it. The configuration of refetch is done by editing the refetch/config.zon file and (re)compiling its source code.
