Coming from Perl and C I have come to expect "\n" to be translated differently depending on OS--especially when doing sockets protocol programming. Ruby *appears* to be subject to this same OS/clib translation issue which is so often overlooked. Was hoping Ruby shielded the average user from this. Has anyone else had any experience confirming or denying this? I've written up the details in a blog post: http://rob.muhlestein.net/2007/01/watch-those-newl...

This works as in Perl and other languages that inherit from C the way newlines are handled[*], except it is simpler because it does not have the MacPerl exception. In these languages you write portable sockets programming by binmodeing the socket and hard-coding "\015\012" or whatever. As a side note, by default modern Perl performs newlines transaltion on CRLF platforms via the custom PerlIO I/O layer, the C Ruby interpreter delegates this to stdio. -- fxn [*] http://www.onlamp.com/pub/a/onlamp/2006/08/17/understanding- newlines.html
