Mingw Replaces \r with \n

[aj.palkovic]

This line of code demonstrates the problem:
File.open('test', 'w'){|f| f.write "a\rb"}; File.read('test')

This should produce "a\rb". That is what MRI 1.9.2 on Ubuntu produces
as well.
However, Mingw produces: "a\nb"

ruby -v:
ruby 1.9.2p180 (2011-02-18) [i386-mingw32]

Is this the expected behavior? It seems weird, especially because
ruby on linux does not change the data.

This is not "MinGW" but how files works on Windows.

On Windows files can be open as text-mode and binary-mode. Text-mode
is the default for Ruby.

On Linux/OSX, binary-mode is the only mode available.

If you want your file line-endings not be transformed by Ruby
automatically, open the file in binary mode:

File.open("test", "wb") { |f| f.write "a\rb" }

Sometimes I wish Ruby completely ignored Windows text-mode files and
used binary by default...

Cool.  I figured it was something weird like that, but I couldn't find much.

Thanks.
