Function std.path.driveName

Get the drive portion of a path.

auto auto driveName(R) (
  R path
if (isRandomAccessRange!R && hasSlicing!R && hasLength!R && isSomeChar!(ElementType!R) && !isSomeString!R);

auto auto driveName(C) (
  C[] path
if (isSomeChar!C);


path string or range of characters


A slice of path that is the drive, or an empty range if the drive is not specified. In the case of UNC paths, the network share is returned.

Always returns an empty range on POSIX.


import std.range : empty;
version (Posix)  assert(driveName("c:/foo").empty);
version (Windows)
    writeln(driveName(`d:file`)); // "d:"
    writeln(driveName(`d:\file`)); // "d:"
    writeln(driveName("d:")); // "d:"
    writeln(driveName(`\\server\share\file`)); // `\\server\share`
    writeln(driveName(`\\server\share\`)); // `\\server\share`
    writeln(driveName(`\\server\share`)); // `\\server\share`

    static assert(driveName(`d:\file`) == "d:");
