Functions

func Debug

func Debug(message string)

Debug logs a debug message with a cyan [DEBUG] prefix and timestamp. Debug messages are only shown when log level is set to LevelDebug. Now includes internal context support infrastructure.

func Debugf

func Debugf(format string, args ...interface{})

Debugf logs a formatted debug message.

func DisableColors

func DisableColors()

DisableColors disables colored output.

func EnableCallerInfo

func EnableCallerInfo()

EnableCallerInfo enables including caller information in logs.

func Error

func Error(message string)

Error logs an error message with a red [ERROR] prefix and timestamp. Now includes internal context support infrastructure.

func Errorf

func Errorf(format string, args ...interface{})

Errorf logs a formatted error message.

func Info

func Info(message string)

Info logs an informational message with a blue [INFO] prefix and timestamp. Now includes internal context support infrastructure.

func Infof

func Infof(format string, args ...interface{})

Infof logs a formatted informational message.

func SetConfig

func SetConfig(config LoggerConfig)

SetConfig updates the global logger configuration.

func SetMinLevel

func SetMinLevel(level LogLevel)

SetMinLevel sets the minimum log level for output.

func SetOutput

func SetOutput(writer io.Writer)

SetOutput sets the output writer for logs.

func Success

func Success(message string)

Success logs a success message with a green [SUCCESS] prefix and timestamp. Now includes internal context support infrastructure.

func Successf

func Successf(format string, args ...interface{})

Successf logs a formatted success message.

func Warning

func Warning(message string)

Warning logs a warning message with a yellow [WARNING] prefix and timestamp. Now includes internal context support infrastructure.

func Warningf

func Warningf(format string, args ...interface{})

Warningf logs a formatted warning message.

Types

type FieldLogger

type FieldLogger struct {
	// contains filtered or unexported fields
}

FieldLogger provides structured logging with additional fields.

func WithFields

func WithFields(fields map[string]interface{}) *FieldLogger

WithFields creates a structured log entry with additional fields. This provides a foundation for structured logging while maintaining simplicity.

func (*FieldLogger) Debug

func (f *FieldLogger) Debug(message string)

Debug logs a debug message with structured fields.

func (*FieldLogger) Error

func (f *FieldLogger) Error(message string)

Error logs an error message with structured fields.

func (*FieldLogger) Info

func (f *FieldLogger) Info(message string)

Info logs an info message with structured fields.

func (*FieldLogger) Success

func (f *FieldLogger) Success(message string)

Success logs a success message with structured fields.

func (*FieldLogger) Warning

func (f *FieldLogger) Warning(message string)

Warning logs a warning message with structured fields.

type LogLevel

type LogLevel int

LogLevel represents the severity level of log messages.

const (
	LevelDebug   LogLevel = iota // LevelDebug represents debug-level messages
	LevelInfo                    // LevelInfo represents informational messages
	LevelSuccess                 // LevelSuccess represents success messages
	LevelWarning                 // LevelWarning represents warning messages
	LevelError                   // LevelError represents error messages
)

func (LogLevel) String

func (l LogLevel) String() string

String returns the string representation of the log level.

type LoggerConfig

type LoggerConfig struct {
	MinLevel     LogLevel  // MinLevel specifies the minimum log level to output
	EnableColors bool      // EnableColors specifies whether to use colored output
	Output       io.Writer // Output specifies the output writer for logs
	EnableCaller bool      // EnableCaller specifies whether to include caller information
	TimeFormat   string    // TimeFormat specifies the timestamp format
}

LoggerConfig holds configuration for the logger.
