Package neinp is a toolkit to implement 9p servers.
A 9p filesystem is created by implementing the P2000 interface, which is then used as argument for NewServer. Server can then use an io.ReadWriter supplied to the Serve method handle requests using the aforementioned P2000 implementer.
See https://git.sr.ht/~rbn/rssfs for an example.
NB: This isn't really polished yet, things may break.

type NopP2000 struct{}
NopP2000 is a dummy impementation of interface P2000, returning error for every call. It can be embedded into own implementations if some functions aren't required. For a working mount (with p9p 9pfuse or linux kernel module), at least Version, Attach, Stat, Walk, Open, Read, and Clunk need to be implemented.
type P2000 interface { Version(context.Context, message.TVersion) (message.RVersion, error) Auth(context.Context, message.TAuth) (message.RAuth, error) Attach(context.Context, message.TAttach) (message.RAttach, error) Walk(context.Context, message.TWalk) (message.RWalk, error) Open(context.Context, message.TOpen) (message.ROpen, error) Create(context.Context, message.TCreate) (message.RCreate, error) Read(context.Context, message.TRead) (message.RRead, error) Write(context.Context, message.TWrite) (message.RWrite, error) Clunk(context.Context, message.TClunk) (message.RClunk, error) Remove(context.Context, message.TRemove) (message.RRemove, error) Stat(context.Context, message.TStat) (message.RStat, error) Wstat(context.Context, message.TWstat) (message.RWstat, error) Close() error }
P2000 is the interface which file systems must implement to be used with Server. To ease implementation of new filesystems, NopP2000 can be embedded. See the types defined in message for documentation of what they do.
type Server struct { Debug bool // contains filtered or unexported fields }
Server muxes and demuxes 9p messages from a connection, calling the corresponding handlers of a P2000 interface.
Code:
fs := &neinp.NopP2000{} l, err := net.Listen("tcp", "localhost:9999") if err != nil { fmt.Println("listen:", err) return } for { c, err := l.Accept() if err != nil { fmt.Println("accept:", err) return } s := neinp.NewServer(fs) if err := s.Serve(c); err != nil { fmt.Println("serve:", err) return } }
NewServer returns a Server initialized to use fs for message handling.
func (s *Server) Serve(rw io.ReadWriter) error
Serve the filesystem on the connection given by rw.
Shutdown serving the filesystem.
