Functions

func Eval

func Eval(root string, directory string, options EvalOptions) (string, error)

Eval evaluates the directory's path, including any intermediate symbolic links. If root is specified and the current OS supports it, and the calling process has the necessary privileges, evaluation is performed in a chrooted context. If the directory is specified as an absolute path, it should either be the root directory or a subdirectory of the root directory. Otherwise, the directory is treated as a path relative to the root directory.

func Get

func Get(root string, directory string, options GetOptions, globs []string, bulkWriter io.Writer) error

Get produces an archive containing items that match the specified glob patterns and writes it to bulkWriter. If root and directory are both not specified, the current root directory is used, and relative names in the globs list are treated as being relative to the current working directory. If root is specified and the current OS supports it, and the calling process has the necessary privileges, the contents are read in a chrooted context. If the directory is specified as an absolute path, it should either be the root directory or a subdirectory of the root directory. Otherwise, the directory is treated as a path relative to the root directory. Relative names in the glob list are treated as being relative to the directory.

func Lgetxattrs

func Lgetxattrs(path string) (map[string]string, error)

Lgetxattrs returns a map of the relevant extended attributes set on the given file.

func Lsetxattrs

func Lsetxattrs(path string, xattrs map[string]string) error

Lsetxattrs sets the relevant members of the specified extended attributes on the given file.

func Mkdir

func Mkdir(root string, directory string, options MkdirOptions) error

Mkdir ensures that the specified directory exists. Any directories which need to be created will be given the specified ownership and permissions. If root and directory are both not specified, the current root directory is used. If root is specified and the current OS supports it, and the calling process has the necessary privileges, the directory is created in a chrooted context. If the directory is specified as an absolute path, it should either be the root directory or a subdirectory of the root directory. Otherwise, the directory is treated as a path relative to the root directory.

func Put

func Put(root string, directory string, options PutOptions, bulkReader io.Reader) error

Put extracts an archive from the bulkReader at the specified directory. If root and directory are both not specified, the current root directory is used. If root is specified and the current OS supports it, and the calling process has the necessary privileges, the contents are written in a chrooted context. If the directory is specified as an absolute path, it should either be the root directory or a subdirectory of the root directory. Otherwise, the directory is treated as a path relative to the root directory.

func Remove

func Remove(root string, item string, options RemoveOptions) error

Remove removes the specified directory or item, traversing any intermediate symbolic links. If the root directory is not specified, the current root directory is used. If root is specified and the current OS supports it, and the calling process has the necessary privileges, the remove() is performed in a chrooted context. If the item to remove is specified as an absolute path, it should either be in the root directory or in a subdirectory of the root directory. Otherwise, the directory is treated as a path relative to the root directory.

func Stat

func Stat(root string, directory string, options StatOptions, globs []string) ([]*StatsForGlob, error)

If root is specified and the current OS supports it, and the calling process has the necessary privileges, the stat() is performed in a chrooted context. If the directory is specified as an absolute path, it should either be the root directory or a subdirectory of the root directory. Otherwise, the directory is treated as a path relative to the root directory. Relative names in the glob list are treated as being relative to the directory.
