Variables

var Logger iLogger = &sDummyLogger{} // The Logger

Functions

func HexStringFromRGB

func HexStringFromRGB(rgb [3]float32) string

func HexStringFromRGBA

func HexStringFromRGBA(rgba [4]float32) string

func NewConsoleLogger

func NewConsoleLogger(loglevel any) iLogger

NewConsoleLogger() returns a sConsoleLogger, which prints log messages on os.Stdout.

`loglevel` can be LogLevel/int or string like "none","error","warn","info","debug","trace".

func NewDummyLogger

func NewDummyLogger() iLogger

NewDummyLogger() returns a sDummyLogger, which prints nothing.

func NewWriterLogger

func NewWriterLogger(loglevel any, writer io.Writer) iLogger

NewWriterLogger() returns a sWriterLogger, which prints log messages to the specified io.Writer.

`loglevel` can be LogLevel/int or string like "none","error","warn","info","debug","trace".

func RGBAFromHexString

func RGBAFromHexString(s string) [4]float32

func RGBFromHexString

func RGBFromHexString(s string) [3]float32

func SetLogger

func SetLogger(logger iLogger) iLogger

SetLogger() sets the current logger to be used.

`logger` should be the returned value of either NewConsoleLogger() or NewWriterLogger().
