Sparklines for Rust
I needed a project to learn Rust. This is it!
Inspired by https://github.com/holman/spark and https://gist.github.com/stefanv/1371985
This provides a Rust library sparkline
and executable sparkr
.
sparkr
$ sparkr --theme classic --min -10 2 4 0 3 9 10 8 2 5 6
▅ ▆ ▅ ▆ █ █ █ ▅ ▇ ▇
$ sparkr --statline --theme colour 2 4 0 3 9 10 8 2 5 6
▂ ▄ ▁ ▃ █ █ ▇ ▂ ▅ ▅
min: 0, max: 10, range: 10
$ sparkr -h
sparkr
Usage:
sparkr [--min=<min>] [--max=<max>] [--theme=<theme>] [--statline] <values>...
sparkr [--min=<min>] [--max=<max>] [--theme=<theme>] [--statline]
sparkr (-h | --help)
sparkr --version
Options:
-h --help Show this screen.
--version Show version.
--min=<min> Specify minimum value instead of calculating it.
--max=<max> Specify maximum value instead of calculating it.
--statline Show a line of stats after the sparkline.
--theme=<theme> What theme to use, 'colour' or 'classic' (default).
<values> Just values.
library - sparkline
Add this to your Cargo.toml
:
[dependencies]
sparkline=0.1
This takes a vec of numbers and prints out a sparkline:
extern crate sparkline;
use sparkline::*;
let (min, max) : (f64, f64) = (0.0, 10.0);
let values = vec![2.0, 3.0, 2.0, 6.0, 9.0];
let sparky = select_sparkline(SparkThemeName::Colour);
for num in values.iter() {
let s : &String = sparky.spark(min, max, *num);
print!("{} ", s);
}
Currently the library expects values to be f64
.
