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 = ''开发者_如何学JAVA
playlist_name = gets.chomp + '.m3u'
music.each do |z|
@new += z + '\n'
end
File.open playlist_name, 'w' do |f|
f.write @new
end
Use "\n"
instead of '\n'
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
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)
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"
