How to import text file and split it up by lines

Kristen

7/2/2007 1:58:00 AM

Hello,

Im attempting to analyze a text file, but having trouble splitting it up
into lines (into an array that indexes each line). Then I would like to
print every line.

Here is what I got:

f = File.open("/Users/john/Desktop/text.txt")

f_lines = f.split("\n")

puts f_lines


And here is the error Im getting:
NoMethodError: private method â??splitâ?? called for
#<File:/Users/john/Desktop/text.txt>


Dont know why this isnt working. Should be simple enough...

Can someone help please?

Hi,

you forgot to 'read' file.

f = File.open("/Users/john/Desktop/text.txt")

f_lines = f.read.split("\n")

puts f_lines

Note: you have also 'each_line' in IO, IOString, String, etc.

File.readlines() does everything you need. You don't even need to use
File.new or File.open.

f_lines = File.readlines('/Users/john/Desktop/test.txt')

HTH,

There is a convenient shortcut
File.readlines("/User/....")
