Source

  pub fn normalizePath(comptime T: type, path: []T) RemoveDotDirsError!usize {
    mem.replaceScalar(T, path, '/', '\\');
    const new_len = mem.collapseRepeatsLen(T, path, '\\');

    const prefix_len: usize = init: {

        break :init 0;
    };

    return prefix_len + try removeDotDirsSanitized(T, path[prefix_len..new_len]);
