Function std.path.asNormalizedPath

Normalize a path by resolving current/parent directory symbols ("." and "..") and removing superfluous directory separators. It will return "." if the path leads to the starting directory. On Windows, slashes are replaced with backslashes.

auto asNormalizedPath(R) (
  R path
)
if (isSomeChar!(ElementEncodingType!R) && (isRandomAccessRange!R && hasSlicing!R && hasLength!R || isNarrowString!R) && !isConvertibleToString!R);

Using asNormalizedPath on empty paths will always return an empty path.

Does not resolve symbolic links.

This function always allocates memory to hold the resulting path. Use buildNormalizedPath to allocate memory and return a string.

Parameters

NameDescription
path string or random access range representing the path to normalize

Returns

normalized path as a forward range

Example

import std.array;
writeln(asNormalizedPath("foo/..").array); // "."

version (Posix)
{
    writeln(asNormalizedPath("/foo/./bar/..//baz/").array); // "/foo/baz"
    writeln(asNormalizedPath("../foo/.").array); // "../foo"
    writeln(asNormalizedPath("/foo/bar/baz/").array); // "/foo/bar/baz"
    writeln(asNormalizedPath("/foo/./bar/../../baz").array); // "/baz"
}

version (Windows)
{
    writeln(asNormalizedPath(`c:\foo\.\bar/..\\baz\`).array); // `c:\foo\baz`
    writeln(asNormalizedPath(`..\foo\.`).array); // `..\foo`
    writeln(asNormalizedPath(`c:\foo\bar\baz\`).array); // `c:\foo\bar\baz`
    writeln(asNormalizedPath(`c:\foo\bar/..`).array); // `c:\foo`
    assert(asNormalizedPath(`\\server\share\foo\..\bar`).array ==
            `\\server\share\bar`);
}
