Subject: [ruby-talk:5220] Ruby Book, Eng. tl, ch1 -- code snippet correct?


Dave has kindly let me know that this code generates a warning with
the latest Ruby. It comes from the Ruby Book, ch1, 1.1.8.

Should I change anything?


# grep written in four lines
pat = Regexp.new(ARGV.shift)
while line = gets()
	print line if line =~ pat
end


Thanks.

Jon
