That's because a memory-mapped file appears directly in your
program's memory address space as if it was an array of bytes
(ubyte[]). No interpretation is imposed upon the contents.
If you want lines out of it, try casting the memory to
const(char)[] and using std.algorithm.splitter to get a range
of lines. For example:
auto mmfile = new MmFile("myfile.txt");
auto data = cast(const(char)[]) mmfile[];
auto lines = data.splitter("\n");
foreach (line; lines) {
...
}

Would it be wasteful to cast the entire content into a const
string? Can a memory mapped file be read with a buffer?
a string is the same thing as immutable(char)[] . It would make
no difference with the example above.
