Hello,
I would like to read protobuf-delimted files but I dont know how to parse file and how to use DecodeMessage function
thank's for your help

Can you explain what "protobuf-delimited" means?

I found a way to do that with GO but I'm not sure it's the right way :

fileContent, err := ioutil.ReadFile(fileName)
        if err != nil {
            if os.IsNotExist(err) {
                fmt.Printf("%s: File not found.  Creating new file.\n", feedName)
            } else {
                log.Fatalln("Error reading file:", err)
            }
    }
 myMessage := &MyMessage{}
 myBuffer := proto.NewBuffer(fileContent)    
 for {
  errParse := myBuffer.DecodeMessage(myMessage)        
   if (errParse == nil) {
       fmt.Println(myMessage.GetField1(), myMessage.GetField2())
       continue;
   }
 }

That is reasonable so long as fileContents is comprised of a sequence of records where each record is a varint-encoded length, followed by the raw bytes of a protobuf message of that length.

There are many ways to do this. We do not provide support for any given "official" sequencing scheme.
