Subject: Re: Read last line of a file

# require "elif"
# last_line = Elif.open(path) { |f| f.gets }

cool.

wc reminds me, i'm looking for a gem that reverses the behaviour of string/collection/io/ traversals, like

#file reverse
require "in_reverse"
last_line = File.open(path).in_reverse { |f| f.gets }

#array reverse
%w(this is a test).each.in_reverse {|x| p x}
test
a
is
this

#string reverse
"this is a test".each_char.in_reverse {|c| p c; break if c=="a"}
t
s
e
t

a
