Sample use:
func CommandPuts(i *picol.Interp, argv []string, pd interface{}) (string, error) {
if len(argv) != 2 {
return "", fmt.Errorf("Wrong number of args for %s %s", argv[0], argv)
}
fmt.Println(argv[1])
return "", nil
}
...
interp := picol.InitInterp()
// add core functions
interp.RegisterCoreCommands()
// add user function
interp.RegisterCommand("puts", CommandPuts, nil)
// eval
result, err := interp.Eval(string(buf))
if err != nil {
fmt.Println("ERROR", err, result)
} else {
fmt.Println(result)
}
