This is how Ruby programmers kill time!

It all started with looking at a text only loader for a Linux package on the terminal, and ended in a heart warming video about a rescue operation, written purely in ruby! No this isn’t a clickbait, but you need to execute (see) it to believe it ;)

Below are some cool Ruby one liners : “text only loader/processing/progress indicators” && “some FUN”

	# Loader for infinite time
	["\|", "/", "-", "\\"].each{\|v\| STDOUT.write "\r#{v}"; sleep 0.5} while 1

	# In case you want to run it for a few seconds (~ 20s in the example below)
	10.times{ ["\|", "/", "-", "\\"].each{\|v\| STDOUT.write "\r#{v}"; sleep 0.5} }

	# Progress Bar
	100.times{STDOUT.write "\|"; sleep 0.1}

	# Another kind of loading indicator
	(f=rand(20); STDOUT.write "\r#{'\|'f}#{'#'15}#{'\|'*(20-f)}"; sleep 0.5) while 1

	# Dog drowning in sea waves ;)
	(f=rand(10); STDOUT.write "\r#{'~'f}^o^#{'~'(20-f)}"; sleep 0.5) while 1

	# Travelling ship =P
	101.times{ \|i\| STDOUT.write "\r#{'~'i}\\____/#{'~'(100-i)}"; sleep 0.2 }

	# Ship rescuing the dog =) #heartWarmingStory
	75.times{ \|i\| f=rand(17); STDOUT.write "\r#{'~'f}^o^#{'~'(17-f)}#{'~'(75-i)}\\___/#{'~'i}"; sleep 0.2 }; STDOUT.write "\r#{'~'17}^o^\\___/#{'~'75}"; sleep 2; 20.times{ \|i\| STDOUT.write "\r#{'~'(19-i)}\\___/#{'~'(i+76)}"; sleep 0.2 }
