Line Ending Confusion on Windows

[Zach Dennis]

I am testing some various line endings and conversions. I am confused
because when I create a file using DOS (CR/LF) format and I do a simple:

fh = File.open( "myfile.txt" );
fh.each_byte{ |ch|
puts ch; end

I get the following output:

72
101
108
108
111
44
10
87
111
114
108
100
33
10

myfile.txt contains:

Hello,
World!


By reading this output you would think it is in Unix format (LF), but it is
actually in DOS (CR/LF) file format.
When I open the file up in a hexeditor (NitroHex) it shows that the file
format is actually in DOS (CR/LF). I am using Ruby 1.8.1preview3 on Windows
2000. Is the Ruby Interpretor screwing up my line endings?

This actually came up from because I was trying what was suggest by a March
post by "Josef 'Jupp' Schugt" about any to any conversions for line endings.
But it doesn't work on my Windows box.

Any input is appreciated,

Zach Dennis

By reading this output you would think it is in Unix format (LF), but it is
actually in DOS (CR/LF) file format.

Ruby automatically converts platform-specific (\r\n in your case)
newlines to platform-independent newlines (\n). This is a feature.

If you don't want any line ending conversations to happen just specify
the binary mode like this: File.open("filename", "rb") { ... }
