digitalmars.D - Extra Carriage Returns using write

reply "Dave G" <dgregory00 gmail.com> writes:
Hello,

Why does the following add an extra CR in front of the CRLF's

auto outf = new File("out.txt", "w");
outf.write("this\r\nis\r\na\r\ntest");
outf.close;

If I make the file binary
auto outf = new File("out.txt", "wb");

it works as expected.

I am using 2.065 and windows 7

Thanks,
Dave G

The bug is in DMC's C runtime, to which Windows DMD defers for file I/O. Also note, File is a Ref-counted struct. You do not need to 'new' it: auto outf = File("out.txt", "wb"); -Steve

Ok, Thanks Steve. Is that something that is going to be fixed?

You would have to ask Walter. Probably the best place is to ask on the DMC forums. See here: http://digitalmars.com/NewsGroup.html -Steve

Redirection of D's I/O through the C runtime needs to be killed with fire. It inherits C's flaws like the various vendor specific extensions to the mode string for important flags like inheritance of file handles in child processes. -- Marco

I'm working on it. There are so many reasons to remove it. Of course, it will still have to be the default. -Steve
