Hi, Octave maintainers,

On macOS, at least with a Qt build, the default EOL mode for Octave as of 4.4.1 is "Mac (CR)".

I think this might be an archaism: "Mac" (\r) EOL mode text files were used by pre-OS X Mac OSes like Mac OS 9. Since the switch to the Unix-based OS X, Mac programs generally default to Unix style (\n) line endings. You can verify this by opening TextEdit and creating a new plain text file: it uses \n EOLs.

Having files created in legacy Mac (\r) mode makes it a bit harder to use Unix command line tools and stuff like GitHub with those files.

Can/should Octave be changed to default to Unix (\n) EOLs on macOS?

If that is what is currently used by default on macos by other applications then I think we should switch. We would, of course, still support files with CR line endings, but create new files with LF.

Do we currently detect the line endings in the file and try to match the usage? If not, should we? How difficult would it be?

Now, if Windows would just abandon CRLF in favor of LF only...
