Word Count (Ruby)


s = "Never eat shredded wheat"
puts s.split.count
# => 4

If you don't want to count underscores and digits:

s = "Never eat shredded wheat 1 _ ?"
puts s.split.reject { |w| w =~ /(W|_|d)/ }.count
# => 4

even more advanced regexp:

s = "Never __ 111 ?? eat shredded
wheat. _Word?"
p s.split.reject { |w| w !~
/([a-zA-Z]+(_[a-zA-Z]+)*)/ }
# => ["Never", "eat", "shredded", "wheat.",
