Force newline only on Windows

[Steve V]

How can I force \n in my strings to be *only* a newline character and not a
carriage return/newline combination on Windows?

Thanks,
Steve

Hi 'talk!

Is there anything in Rubyland like SciPy?

URL: http://www.scipy.org/About/

In short, it is a collection of scientific tools, combining a lot of
numeric functions, data visualization/plotting routines etc into a
single package. (The part I liked was about how it can transform the
Python command line interpreter to a very capable Math/Analysis tool)

Does any combination of Ruby libraries offer the same sort of functionality?

Thanks in advance!
Shajith

PS: Apologies if this sounds like another of those "Ruby vs Python" things.

PS1: Right now, I am aware of Narray. I'm also looking for some more
functionality(optimization?, plotting, etc)

It's always just a newline in strings. I guess you mean you want the \n
in a file written:

09:14:10 [temp]: irb
irb(main):001:0> File.open("x","wb") {|io| io.puts "foo\nbar"}
=> nil
irb(main):002:0> exit
09:15:51 [temp]: od -t c x
0000000 f o o \n b a r \n
0000010
09:15:56 [temp]:

Kind regards

Use "binary" mode when opening your file, or invoke the "binmode" method
on your IO object.

File.open("x.txt", "wb") do |file|
file.print "\n"
end

On Windows, x.txt will contain only "\n". If you leave out the "b", you
will get "\r\n" instead.

STDOUT.binmode
print "\n"

This will make the same change to stdout.
