Sparkr is a port of spark for Ruby.
It lets you create ASCII sparklines for your Ruby CLIs: ▁▂▃▅▇
Install via rubygems
$ gem install sparkr
You can get/browse the source code at http://github.com/rrrene/sparkr
Shell meets …
After the installation, run
sparkr in your shell of choice and pass it a list of numbers (just like
you would with spark).
The output is what you would expect:
$ sparkr 0 30 55 80 33 150 ▁▂▃▅▂▇
But the real reason for this port is the ability to use this in a Ruby application, namely your personal CLI projects.
Sparkr.sparkline([0,30,55,80,33,150]) # => "▁▂▃▅▂▇"
