If i just do "printf(input);" it works until it gets to a blank line.

In all cases it gives "Error: Access Violation" when it crashes.

--- Begin hello.d
import c.stdio;
import stream;

int main( char[][] args )
{
char[] input="";
File myFile = new File(args[1]);
while( ! myFile.eof() )
{
input = myFile.readLine();
printf("%s\n", input);
}
myFile.close();
return 0;
}
--- End hello.d

Use

"%.*s\n".

What about the multiple lines? and when i use printf(input);
?
input isn't always declared? I'm assuming since result in the stream class is
a resizable array when it doesn't get anything it it it's a pointer to an array
of length zero? Thus accessing it blows up?  Why would "%.*s" fix that?

Use

"%.*s\n".


I just switched to using that now, and it works.
to some extent.. If the last line of the file doesn't end in a newline it spews
this out: 

not enough data in stream

Although looking at it more i think dli
0.1.2 just has an old version of phobos. (I tried updating but it failed to
compile parts of phobos then)

The input[] is a dynamic array, which consists of a length field and a
pointer to the data. %s expects a pointer to a null terminated string. %.*s
expects two parameters, a length and a pointer, which fits perfectly with D
arrays.
