asAbsolutePath

auto asAbsolutePath(R)(R path) if ((isRandomAccessRange!R &&  isSomeChar!(ElementType!R)  ||
     isNarrowString!R)  &&
    !isConvertibleToString!R)

Transforms path into an absolute path.

The following algorithm is used:

If path is empty, return null.
If path is already absolute, return it.
Otherwise, append path to the current working directory,
which allocates memory.

Note that asAbsolutePath will not normalize `..` segments. Use asNormalizedPath(asAbsolutePath(path)) if that is desired.
