Idiomatic Go 9P2000.L client and server, extracted from gVisor for general use

p9

p9 is a Golang 9P2000.L client and server originally written for gVisor. p9 supports Windows, BSD, and Linux on most Go-available architectures.

Server Example

For how to start a server given a p9.Attacher implementation, see cmd/p9ufs.

For how to implement a p9.Attacher and p9.File, see as an example staticfs, a simple static file system. Boilerplate templates for p9.File implementations are in templatefs.

A test suite for server-side p9.Attacher and p9.File implementations is being built at fsimpl/test.

Client Example

import (
    "log"
    "net"

    "github.com/hugelgupf/p9/p9"
)

func main() {
  conn, err := net.Dial("tcp", "localhost:8000")
  if err != nil {
    log.Fatal(err)
  }

  // conn can be any net.Conn.
  client, err := p9.NewClient(conn)
  if err != nil {
    log.Fatal(err)
  }

  // root will be a p9.File and supports all those operations.
  root, err := client.Attach("/")
  if err != nil {
    log.Fatal(err)
  }

  // For example:
  _, _, attrs, err := root.GetAttr(p9.AttrMaskAll)
  if err != nil {
    log.Fatal(err)
  }

  log.Printf("Attrs of /: %v", attrs)
}
