I would like to know what it does:
File.open(filename,"r").each_file do |line|
if (!line.strip.empty? and !line.starts_with?(" "))
....
.....
end
end
Especially what isstrip? Thanks for your time!
Strip removes all the leading and trailing whitespace chars from a string. In essense the code you pasted checks if the sting contains anything apart from whitespaces AND the first symbol is not a space.
