class RuboCop::Formatter::PacmanFormatter

github.com/go-labs/rspec_pacman_formatter<br>This is inspired by the Pacman formatter for RSpec by Carlos Rojas.
Otherwise it will print a Ghost.
Pacman will “eat” one PACDOT per file when no offense is detected.
This formatter prints a PACDOT per every file to be analyzed.
