Encode/Decode between struct and byte slice

sbs stands for Struct to Byte Slice and back to Struct Internals: sbs encodes your struct first to a Gob, then it convers it to a byte slice; it reverses the process for decoding. Example type Foo struct { A int B string } p := &Foo{111,"A string"} byteslice, err := sbs.Enc(p) ... foo := new(Foo) structobject, err := sbs.Dec(foo, byteslice) ... Code is available at


GoTamer gowatch is a fork of with some enhancements. gowatch -test will run go test on the folder gowatch -build will run go build on the folder gowatch -run [program_name] will run go build and then it will execute [program_name] If a file changes while running lets say gowatch -run [program_name] it will kill [program_name], run gowatch -build on the folder, and then restart [program_name] Links Website Pkg Documentationn Repository


There are two ways to ping go internal ping sys ping The go internal ping works only as root, therefor a sys ping is also provided until I can figure out how to fix this problem. Website Code is available at


Now gotamer/mail also implements the io.Writer interface. Example: package main import ( "fmt" "" ) func main() { s := new(mail.Smtp) s.SetHostname("") s.SetHostport(587) s.SetFromName("GoTamer") s.SetFromAddr("") s.SetPassword("*********") s.AddToAddr("") s.SetSubject("GoTamer test smtp mail") s.SetBody("The Writer below should replace this default line") if _, err := fmt.Fprintf(s, "Hello, smtp mail writer\n"); err != nil { fmt.Println(err) } } As an alternative to AddToAddr() there is SetToAddrs(). With SetToAddrs() you can set one or more recipients as a comma separated list.

Encode/Decode Golang data to Gob files

Golang has a package called Gob to encode and decode values in to go specific binary format for transmiting as streams or for saving to file. Below are two functions, Load and Save to encode/decode go values including struct’s in to files. package main import ( "encoding/gob" "fmt" "os" "runtime" ) const file = "/tmp/test.gob" type User struct { Name, Pass string } func main(){ var datato = &User{"Donald","DuckPass"} var datafrom = new(User) err := Save(file, datato) Check(err) err = Load(file, datafrom) Check(err) fmt.
