Types

type Logger

type Logger interface {
	Debug(msg string, ctx ...interface{})
	Info(msg string, ctx ...interface{})
	Warn(msg string, ctx ...interface{})
	Error(msg string, ctx ...interface{})
	Crit(msg string, ctx ...interface{})
}

Logger writes key/pair values to a handler

func Init

func Init(serviceName, contextName string, args ...string) Logger

Init instantiates the logger with the specified arguments.

The first `args` parameter is the logger filename (default: logger.log).

The second `args` parameter indicates whether to get rid of any file logging (default: "false"). You might want to use the `logger.NO_FILE` constant as this second parameter or the string "true", eg.

log := logger.Init("my_package", "MyFunction", "", logger.NO_FILE)

IMPORTANT: The logger will log to stderr and to the file unless stated otherwise.

func InitHandler

func InitHandler(serviceName, contextName, requestID string, args ...string) Logger

InitHandler is generally used in API handlers to display the request ID.

IMPORTANT: The logger will log to stderr and to the file.
