Loading a file in a buffer...

[Zangief Ief]

Hello everybody,

I would like to load the exact content of a file in a buffer (with the
same carriage return). To do so, I had trying this:

file = File.open('/home/my_file')

To verify if that work normally, I had try to add this for display the
content of my_file:

puts file

But my_file was not been printed, and I got: #<File:0x28d70>


If you know a way to do so, please help me
Thanks.

To get the contents of a file, opening it is not enough. You need to
explicitly read its contents. There are many methods which allow to access the
contents of a file: read, readlines, each_line, each_byte, File.read,
File.readlines, File.foreach (the last three are class methods). They're
documented under class IO (from which File is derived). If you only need to
read the contents of the file you don't need to use File.open at all, but
simply use File.read:

contents = File.read('/home/my_file'/)

I hope this helps

while (line = infile.gets)
puts "#{counter}: #{line}"
counter = counter + 1
end

Try

buffer = IO.read('/home/my_file')

or

buffer = File.read('/home/my_file')

They both do the same thing because File inherits 'read' from IO.

Thanks! 'read' method works very well
