Displays sparklines on the terminal.
uspark scans over all given arguments to detect the minimum and maximum
values. Afterwards, it maps each values to a glyph from a defined set to build
the sparkline. The terminal must support UTF-8 encoded characters.
uspark [OPTS --] <number-1> [<number-2> … ]
Options
-h - show help
-bars - use bars (default)
-lines - use lines
-braille - use braile characters
Use -- to separate options from arguments / numbers.
Environment Variables:
- USPARK_MIN: Use
USPARK_MINas the minimum value - USPARK_MAX: Use
USPARK_MAXas the maximum value
Magnitude of earthquakes over 1.0 in the last 24 hours:

xargs ./uspark

I was interested in how large a self-contained binary written in Rust is in comparison to a statically linked binary written in C. Numbers:
| Compiler | Build | Size of binary |
|---|---|---|
| diet-0.34 + gcc-12.2 | diet gcc -lstatic | 13288 |
| rustc 1.84.0 (9fc6b4312 2025-01-07) | cargo build --release | 371096 |
GPL2, see COPYING
You need a C-compiler. Then:
$> cd c-lang
$> make
You need a Rust compiler. Then:
$> cd rust-lang
$> cargo build --release
