class Covered::Summary

def print_summary(output = $stdout)

A coverage array gives, for each line, the number of line execution by the interpreter. A nil value means coverage is disabled for this line (lines like else and end). 
def print_summary(output = $stdout)
	self.each do |coverage|
		line_offset = 1
		output.puts "", Rainbow(coverage.path).bold.underline
		
		counts = coverage.counts
		
		File.open(coverage.path, "r") do |file|
			file.each_line do |line|
				count = counts[line_offset]
				
				output.write("#{line_offset}|".rjust(8))
				output.write("#{count}:".rjust(8))
				
				if count == nil
					output.write Rainbow(line).faint
				elsif count == 0
					output.write Rainbow(line).red
				else
					output.write Rainbow(line).green
				end
				
				# If there was no newline at end of file, we add one:
				unless line.end_with? $/
					output.puts
				end
				
				line_offset += 1
