I do something along these lines in most of my real main packages, so that the return err convention is adopted as soon as possible, and has a proper termination: func main() { if err := run(); err != nil { fmt.Fprintf(os.Stderr, “error: %v\n”, err) os.Exit(1) } } func run() error { err := something() … Read more
If you don’t want timestamps, just create a new log.Logger with flag set to 0: l := log.New(os.Stderr, “”, 0) l.Println(“log msg”) EDIT: Is the following good Go? os.Stderr.WriteString(“Message”) This is acceptable, and you can also use fmt.Fprintf and friends to get formatted output: fmt.Fprintf(os.Stderr, “number of foo: %d”, nFoo)
You can set the Flags on either a custom Logger, or the default to include Llongfile or Lshortfile // to change the flags on the default logger log.SetFlags(log.LstdFlags | log.Lshortfile)
The first one should never be used in production code, since it’s transporting information irrelevant to end-users (a user can’t do anything about “Cannot connect to database”). You throw Exceptions if you know that at a certain critical code point, your application can fail and you want your code to recover across multiple call-levels. trigger_error() … Read more

I got the email address (something like xxxxxx@developer.gserviceaccount.com) for the service account by looking under the “API Access” tab in the Google APIs console. Then, I followed Google’s … Read more

But…if you have access to a php.ini file you can do this: error_log = /var/log/php-scripts.log According to rinogo‘s comment: If you’re using cPanel, the master log file you’re probably looking … Read more
