symwalk

import "github.com/edwardrf/symwalk"

symwalk provide a walk function similar to filepath.Walk but follow symbolic links but avoid visiting directories more than once even if there is a symbolic link loop.

Whats the difference from facebookarchive/symwalk

The main difference is this Walk implementation will not visit the same directories more than once even if there is a symbolic link loop. This is achieved by

• always evaluate the symbolic links to its real path by filepath.EvalSymlinks, this means your walk function will received the real path instead of the relative path from the symbolic links
• keep record of all visited directories using a map

Since the underlying implementation make use of filepath.Walk, the rest of the behavior is the same as filepath.Walk.

Example

symwalk.Walk("/tmp/", func(path string, info os.FileInfo, err error) error {
  fmt.Println(path)
  return nil
})
