Walk example

[markpendlebury]

Would someone be kind enough to share an example of how to use walk? Honestly i'm unable to work it out myself from the documentation (i'm still leaning go)

Thanks

Yeah, I'm in the same boat. I looked at the tests for the Walker and then had a second look at the doco.

func main() {

  host   := "ftp.something.host:21"
  folder := "/some_folder"
  user   := "gonzo"
  passwd := "secret"

  c, err := ftp.Dial(host, ftp.DialWithTimeout(5*time.Second))
  if err != nil {
      log.Fatal(err)
  }

  err = c.Login(user, passwd)
  if err != nil {
      log.Fatal(err)
  }  

  w := c.Walk(folder)

  ok := w.Next() // Get next (first) entry in the tree
  for ok == true {
    e := w.Stat() // Get the current entry
    fmt.Println(e.Type, e.Name, w.Path())
    ok = w.Next() // Get next
  }

  if err := c.Quit(); err != nil {
      log.Fatal(err)
  }

}

It's pretty similar to other libraries :)

package main

import (
	"fmt"
	"io"
	"log"
	"time"

	"github.com/jlaffaye/ftp"
)

func main() {
	conn, err := ftp.Dial("your.host:21", ftp.DialWithTimeout(5*time.Second))
	if err != nil {
		log.Fatal(err)
	}

	if err = conn.Login("username", "password"); err != nil {
		log.Fatal(err)
	}

	walker := conn.Walk("/your/path")

	for walker.Next() {
		// access current full path
		fmt.Println(walker.Path())

		// access entry (file or folder)
		fmt.Println(walker.Stat().Name)
	}

	if walker.Err() != nil && walker.Err() != io.EOF {
		log.Fatal(err)
	}

	if err = conn.Quit(); err != nil {
		log.Fatal(err)
	}
}
