fs

func (*Node) IsDir ¶

func (p *Node) IsDir() (bool, error)

IsDir reports whether the entry describes a directory.

func (*Node) ModTime ¶

func (p *Node) ModTime() (time.Time, error)

ModTime returns the modification time of the file.

func (*Node) Mode ¶

func (p *Node) Mode() (fs.FileMode, error)

Mode returns file mode bits.

func (*Node) Name ¶

func (p *Node) Name() (string, error)

Name returns the name of the file (or subdirectory) described by the entry. This name is only the final element of the path (the base name), not the entire path. For example, Name would return "hello.go" not "home/gopher/hello.go".

func (*Node) Size ¶

func (p *Node) Size() (int64, error)

Size returns the size of the file in bytes. If the file is a directory, the size is system-dependent and should not be used.

func (*Node) Sys ¶

func (p *Node) Sys() (any, error)

Sys returns the underlying data source (can return nil).

func (*Node) Type ¶

func (p *Node) Type() (fs.FileMode, error)

Type returns the type bits for the entry. The type bits are a subset of the usual FileMode bits, those returned by the FileMode.Type method.

func (NodeSet) All ¶

func (p NodeSet) All() NodeSet

All returns a NodeSet containing all nodes. It's a cache operation for performance optimization when you need to traverse the nodes multiple times.

func (NodeSet) Collect ¶

func (p NodeSet) Collect() ([]*Node, error)

Collect retrieves all nodes from the NodeSet.

func (NodeSet) Dir ¶

func (p NodeSet) Dir() NodeSet

Dir returns a NodeSet containing all child nodes of the nodes in the NodeSet that are directories.

func (NodeSet) File ¶

func (p NodeSet) File() NodeSet

File returns a NodeSet containing all child nodes of the nodes in the NodeSet that are files (not directories).

func (NodeSet) First ¶

func (p NodeSet) First() (*Node, error)

First returns the first node in the NodeSet.

func (NodeSet) IsDir ¶

func (p NodeSet) IsDir() (is bool, err error)

IsDir reports whether the first node in the NodeSet is a directory.

func (NodeSet) Match ¶

func (p NodeSet) Match(pattern string) NodeSet

Match returns a NodeSet containing all child nodes of the nodes in the NodeSet that match the specified pattern. The pattern syntax is the same as in path.Match. For example, "file*.txt" matches "file1.txt" and "file2.txt", but not "myfile.txt".

func (NodeSet) ModTime ¶

func (p NodeSet) ModTime() (modTime time.Time, err error)

ModTime returns the modification time of the first node in the NodeSet.

func (NodeSet) Mode ¶

func (p NodeSet) Mode() (mode fs.FileMode, err error)

Mode returns the file mode of the first node in the NodeSet.

func (NodeSet) Name ¶

func (p NodeSet) Name() (name string, err error)

Name returns the name of the first node in the NodeSet.

func (NodeSet) Ok ¶

func (p NodeSet) Ok() bool

Ok returns true if there is no error in the NodeSet.

func (NodeSet) OnError ¶

func (p NodeSet) OnError(onErr func(error) bool) NodeSet

OnError calls onErr for any error in the NodeSet and returns a new NodeSet without the nodes that have errors. If onErr returns false, it stops processing and returns a NodeSet without the remaining nodes.

func (NodeSet) One ¶

func (p NodeSet) One() NodeSet

One returns a NodeSet containing the first node. It's a performance optimization when you only need the first node (stop early).

func (NodeSet) Path ¶

func (p NodeSet) Path() (name string, err error)

Path returns the path of the first node in the NodeSet. The path is the absolute path to the file or directory (relative to the root of the file system). Note the path is not started with a slash. For example, if the root of the file system is "/home/gopher" and the node represents the file "/home/gopher/a/b.go", Path would return "a/b.go". For the root node, Path would return "" (not "/").

func (NodeSet) Single ¶

func (p NodeSet) Single() NodeSet

Single returns a NodeSet containing the single node. If there are zero or more than one nodes, it returns an error. ErrNotFound or ErrMultiEntities is returned accordingly.

func (NodeSet) Size ¶

func (p NodeSet) Size() (size int64, err error)

Size returns the size of the first node in the NodeSet.

func (NodeSet) XGo_Any ¶

func (p NodeSet) XGo_Any(name string) NodeSet

XGo_Any returns a NodeSet containing all descendant nodes (including the nodes themselves) with the specified name. If name is "file", it returns all file nodes. If name is "dir", it returns all directory nodes. If name is "", it returns all nodes.

• .**.file
• .**.dir
• .**.*

func (NodeSet) XGo_Child ¶

func (p NodeSet) XGo_Child() NodeSet

XGo_Child returns a NodeSet containing all child nodes of the nodes in the NodeSet.

func (NodeSet) XGo_Enum ¶

func (p NodeSet) XGo_Enum() iter.Seq[NodeSet]

XGo_Enum returns an iterator over the nodes in the NodeSet.

func (NodeSet) XGo_first ¶

func (p NodeSet) XGo_first() (ret *Node, err error)

_first returns the first node in the NodeSet. It's required by XGo compiler.
