ruby each_line comparison only returns last string -

code:

class comparer  words = "asdf-asdf-e-e-a-dsf-bvc-onetwothreefourfive-bob-john" foundwords = []  file.foreach('words.txt') |line|     substr = "#{line}"     if words.include? substr         puts "found " + substr         foundwords << substr                 end end  wordlist = foundwords.join("\n").to_s                puts "words found: " + wordlist  end 

words.txt:

one blah-blah-blah 123-5342-123123 onetwo onetwothree onetwothreefour 

i'd code return instances of include?, when code run, wordlist contains last line of words.txt ("onetwothreefour".) why don't other lines in words.txt factored?

because other lines expect found, have "hidden" newline character @ end. can see yourself.

file.foreach('words.txt') |line|   puts line.inspect   # or   p line end 

you can rid of newlines using chomp! method on line.

file.foreach('words.txt') |line|   line.chomp!    # proceed logic end
