Previous changes from v1.22.0

  • ✨ Enhancements:

    • 🌲 #1071: Add zap.Objects and zap.ObjectValues field constructors to log arrays of objects. With these two constructors, you don't need to implement zapcore.ArrayMarshaler for use with zap.Array if those objects implement zapcore.ObjectMarshaler.
    • 🏗 #1079: Add SugaredLogger.WithOptions to build a copy of an existing SugaredLogger with the provided options applied.
    • 🌲 #1080: Add *ln variants to SugaredLogger for each log level. These functions provide a string joining behavior similar to fmt.Println.
    • #1088: Add zap.WithFatalHook option to control the behavior of the logger for Fatal-level log entries. This defaults to exiting the program.
    • #1108: Add a zap.Must function that you can use with NewProduction or NewDevelopment to panic if the system was unable to build the logger.
    • 🌲 #1118: Add a Logger.Log method that allows specifying the log level for a statement dynamically.
