紅寶石長度不顯示數組的正確長度

Question

我有一個名爲quotes.txt的八行文件。當我運行下面的代碼時，它輸出一個包含8個項目並且長度爲1的數組。

我期待8而不是1.我在這裏做錯了什麼？

#!/usr/bin/env ruby 
# myrandom_sig.rb 

filename = ARGV[0] || (ENV['HOME'] + '/Documents/rubybyexample/RBE_scripts/quotes.txt') 
quotation_file = File.new(filename, 'r') 
file_lines = quotation_file.readlines() 
quotation_file.close() 
quotations  = file_lines.to_s.split("\n\n") 
puts quotations 
puts quotations.length 

輸出

➜ RBE_scripts ruby -w myrandom_sig.rb quotes.txt 
["It is better to 
have loved and lost than just to have lost.\n", "It is bad luck to be 
superstitious.\n", "If it jams, force it. If it breaks, it needed 
replacement anyway.\n", "Always remember that you are unique. Just 
like everyone else.\n", "A woman without a man is like a fish without 
a bicycle.\n", "A bachelor is a guy who is footloose and fiancee 
free.\n", "If Yoda a great Jedi master he is, why not a good sentence 
construct can he?\n", "People will remember you better if you always 
wear the same outfit.\n"]

這是quotations.inspect輸出：

["[\"Test\\n\", \"Line 2\\n\", \"Line 3 and some \\n\"]"] 

的問題，從你打電話file_lines.to_s.split("\n\n")莖。您將數組強制轉換爲字符串，然後返回到數組。

這裏是你想要做什麼：

filename = ARGV[0] || (ENV['HOME'] + '/Documents/rubybyexample/RBE_scripts/quotes.txt') 
quotation_file = File.new(filename, 'r') 
quotations = quotation_file.readlines() 
quotation_file.close() 
puts quotations.size
