    type FileSystem

    type FileSystem interface {
    	// ReadDir reads the directory named by dirname and returns a
    	// list of directory entries.
    	ReadDir(dirname string) ([]os.FileInfo, error)
    	// Lstat returns a FileInfo describing the named file. If the file is a
    	// symbolic link, the returned FileInfo describes the symbolic link. Lstat
    	// makes no attempt to follow the link.
    	Lstat(name string) (os.FileInfo, error)
    	// Join joins any number of path elements into a single path, adding a
    	// separator if necessary. The result is Cleaned; in particular, all
    	// empty strings are ignored.
    	// The separator is FileSystem specific.
    	Join(elem ...string) string

      FileSystem defines the methods of an abstract filesystem.

      type Walker

      type Walker struct {
      	// contains filtered or unexported fields

        Walker provides a convenient interface for iterating over the descendants of a filesystem path. Successive calls to the Step method will step through each file or directory in the tree, including the root. The files are walked in lexical order, which makes the output deterministic but means that for very large directories Walker can be inefficient. Walker does not follow symbolic links.


        func Walk

        func Walk(root string) *Walker

          Walk returns a new Walker rooted at root.

          func WalkFS

          func WalkFS(root string, fs FileSystem) *Walker

            WalkFS returns a new Walker rooted at root on the FileSystem fs.

            func (*Walker) Err

            func (w *Walker) Err() error

              Err returns the error, if any, for the most recent attempt by Step to visit a file or directory. If a directory has an error, w will not descend into that directory.

              func (*Walker) Path

              func (w *Walker) Path() string

                Path returns the path to the most recent file or directory visited by a call to Step. It contains the argument to Walk as a prefix; that is, if Walk is called with "dir", which is a directory containing the file "a", Path will return "dir/a".

                func (*Walker) SkipDir

                func (w *Walker) SkipDir()

                  SkipDir causes the currently visited directory to be skipped. If w is not on a directory, SkipDir has no effect.

                  func (*Walker) Stat

                  func (w *Walker) Stat() os.FileInfo

                    Stat returns info for the most recent file or directory visited by a call to Step.

                    func (*Walker) Step

                    func (w *Walker) Step() bool

                      Step advances the Walker to the next file or directory, which will then be available through the Path, Stat, and Err methods. It returns false when the walk stops at the end of the tree.
