Issue #4515 has been reported by Yen-Nan Lin.

Bug #4515: File.each_line read all lines of file as one line
http://redmine.ruby-lang.org/issues/4515

Author: Yen-Nan Lin

ruby -v: ruby 1.9.2p180 (2011-02-18 revision 30909) [i386-darwin9.8.0]


I access a tab-delimited text file from Excel, the text file is 5 lines in my editors (TextEdit, TextWrangler).

However, when I use File.each_line to read it, this method only iterate once and combine 5 lines to 1 line.

I expect my code to puts count = 5, but it print 1.

Below is my code, the test2.txt file is in attachment if you need. 

----------------------------------------------------

filePath = "test2.txt"

data = Array.new

File.open(filePath, 'r') do |f|
	count = 0
	f.each_line do |line|
		data << line.split.map { |entry| entry.to_i }
		count += 1
	end
	puts count	
end

----------------------------------------------------------

I find a solution in http://railsforum.com/viewtopic.php?id=15582

But I think this bug should be solved.

Thank you very much!!
