Function std.path.buildNormalizedPath

Performs the same task as buildPath, while at the same time 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.

{null} buildNormalizedPath(C)()
if (isSomeChar!C);

Using buildNormalizedPath on null paths will always return null.

Note that this function does not resolve symbolic links.

This function always allocates memory to hold the resulting path. Use asNormalizedPath to not allocate memory.

Parameters

NameDescription
paths An array of paths to assemble.

Returns

The assembled path.

Example

writeln(buildNormalizedPath("foo", "..")); // "."

version (Posix)
{
    writeln(buildNormalizedPath("/foo/./bar/..//baz/")); // "/foo/baz"
    writeln(buildNormalizedPath("../foo/.")); // "../foo"
    writeln(buildNormalizedPath("/foo", "bar/baz/")); // "/foo/bar/baz"
    writeln(buildNormalizedPath("/foo", "/bar/..", "baz")); // "/baz"
    writeln(buildNormalizedPath("foo/./bar", "../../", "../baz")); // "../baz"
    writeln(buildNormalizedPath("/foo/./bar", "../../baz")); // "/baz"
}

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