I'm not a fan of the built-in "pretty-printed" debug output (format string "{:#?}") because they don't look so pretty to me. That is why I made this crate.
prettier-print contains two modules. The first is prettier_printer which adds rainbows and stars to the debug string.
// How to use PrettierPrinter
println!;
sparkles prints the debug string, and then runs game of life on top of the printed string.
let stdout = stdout;
new.run?;
