const MaxLogSize = 5 * 1024 * 1024

MaxLogSize is the threshold for log rotation (5MB)

Variables ¶

var NonCriticalPrefixes = []string{
	"[~] Modo prueba activado",
	"[>] Peso enviado",
	"[!] No se recibió peso significativo",
	"[i] Configuración sin cambios",
	"[i] Iniciando escucha",
	"[i] Terminando escucha",
	"[+] Cliente conectado",
	"[-] Cliente desconectado",
}

NonCriticalPrefixes are log messages filtered when verbose=false

Functions ¶

func Flush ¶

func Flush(path string) error

Flush reduces the log file to the last 50 lines

func GetFileSize ¶

func GetFileSize(path string) int64

GetFileSize returns the size of the log file in bytes

func ReadLastNLines ¶

func ReadLastNLines(path string, n int) []string

ReadLastNLines reads the last n lines from a file efficiently

func RotateIfNeeded ¶

func RotateIfNeeded(path string) error

RotateIfNeeded truncates the log file if it exceeds MaxLogSize Keeps the last 1000 lines for continuity

Types ¶

type FilteredLogger ¶

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

FilteredLogger wraps a file writer with verbose filtering

func NewFilteredLogger ¶

func NewFilteredLogger(file *os.File, verbose *bool, vMu *sync.RWMutex) *FilteredLogger

NewFilteredLogger creates a logger that can filter non-critical messages

func (*FilteredLogger) Write ¶

func (l *FilteredLogger) Write(p []byte) (n int, err error)

type Manager ¶

type Manager struct {
	FilePath string

	Verbose bool
	// contains filtered or unexported fields
}

Manager handles log file lifecycle and configuration

func Setup ¶

func Setup(serviceName string, defaultVerbose bool) (*Manager, error)

Setup initializes logging to file with stdout fallback for console mode

func (*Manager) Close ¶

func (m *Manager) Close() error

Close closes the log file

func (*Manager) Closer ¶

func (m *Manager) Closer() io.Closer

Closer returns an io.Closer for the log file

func (*Manager) Flush ¶

func (m *Manager) Flush() error

Flush reduces the log file keeping last 50 lines

func (*Manager) GetStatus ¶

func (m *Manager) GetStatus() map[string]interface{}

GetStatus returns current log status

func (*Manager) GetTail ¶

func (m *Manager) GetTail(n int) []string

GetTail returns the last n lines of the log

func (*Manager) GetVerbose ¶

func (m *Manager) GetVerbose() bool

GetVerbose returns current verbose setting

func (*Manager) SetVerbose ¶

func (m *Manager) SetVerbose(v bool)

SetVerbose updates the verbose setting
