How to do a newline in output

Question

How do I make \n actually work in my output? At the moment it just writes it all in 1 long block. Thanks for any help

Dir.chdir 'C:/Users/name/Music'
music = Dir['C:/Users/name/Music/*.{mp3, MP3}']
puts 'what would you like to call the playlist?'
@new = ''
playlist_name = gets.chomp + '.m3u'

music.each do |z|
  @new += z + '\n'
end

File.open playlist_name, 'w' do |f|
  f.write @new
end

Answer 1

Use "\n" instead of '\n'

Answer 2

I would like to share my experience with \n
I came to notice that "\n" works as-

puts "\n\n" // to provide 2 new lines

but not

p "\n\n"

also puts '\n\n'
Doesn't works.

Hope will work for you!!

You can do this all in the File.open block:

Dir.chdir 'C:/Users/name/Music'
music = Dir['C:/Users/name/Music/*.{mp3, MP3}']
puts 'what would you like to call the playlist?'
playlist_name = gets.chomp + '.m3u'

File.open playlist_name, 'w' do |f|
  music.each do |z|
    f.puts z
  end
end

Answer 4

Actually you don't even need the block:

  Dir.chdir 'C:/Users/name/Music'
  music = Dir['C:/Users/name/Music/*.{mp3, MP3}']
  puts 'what would you like to call the playlist?'
  playlist_name = gets.chomp + '.m3u'

  File.open(playlist_name, 'w').puts(music)

Answer 5

For me it didn't work with adding "\n" to the end of an existing argument to puts, so as a workaround I called print on the next line with "\n" as an argument, although I suppose I could have just called puts again.

This did not produce the desired result:

puts "Coach says: #{coach_answer(user_input)}\n"

But this did:

puts "Coach says: #{coach_answer(user_input)}"
print "\n"

None of the methods mentioned above worked for me, possibly because I was trying to use Ruby on a different platform (Appcircle). Ultimately, adding a space before \n solved the issue. For example:

puts " \nMy new line message."
