a cli for everyone
bbshark
bbshark is now available on crates.io and has had over 660 downloads to date.
bbshark is a blazingly fast CLI tool written in rust that prints a very popular kid’s song.
Motivation
I have come to love command line interface (CLI) tools. They are powerful and fast (my favourite at the moment is bat by the way).
They are useful because I have tasks and jobs to do.
But, if you are a kid, you probably haven’t built up such a to do list.
So, it begs the question, how do we introduce younglings to CLI tools?
Through play.
bbshark is a playful CLI. The user can configure it with command line arguments to modify the printed output for fun.
Usage
Running bbshark with no arguments prints popular lyrics to the screen:
$ bbshark
Baby shark... doo, doo, doo, doo, doo, doo.
Baby shark!
Options
The printed output can be modified using flags that change the animal (-a) from ‘shark’ to ‘dolphin’ and/or the relative (-r) from ‘Baby’ to ‘Sister’:
$ bbshark -a dolphin -r Sister
Sister dolphin... doo, doo, doo, doo, doo, doo.
Sister dolphin!
To view a full list of options, use the help flag (-h or --help):
$ bbshark -h
bbshark 1.0.0
