# Class used to calculates LOC for a provided file list.

# Example:
# files = FileList["lib/active_record/**/*.rb"]
# CodeTools::LineStatistics.new(files).print_loc
module CodeTools
class LineStatistics
# @param files [Array, FileList, Enumerable]
# e.g. FileList["lib/active_record/**/*.rb"]

@files = Array(files).compact
end
# Calculates LOC for each file
# Outputs each file and a total LOC
