- **`FlagShowTimestamp`, `FlagShowLevel`, `FlagDefault`**: Record flag constants controlling output format.
### Console Output Configuration
The logger supports flexible output routing with options to mirror logs to stdout/stderr or disable file output entirely.
**Console-only logging** (no file output):
```go
logger := log.NewLogger()
err := logger.InitWithDefaults(
"enable_stdout=true",
"disable_file=true",
"level=-4", // Debug level
)
defer logger.Shutdown()
logger.Info("This goes only to console")
```
**Dual output** (both file and console):
```go
gologger := log.NewLogger()
err := logger.InitWithDefaults(
"directory=/var/log/app",
"enable_stdout=true",
"stdout_target=stderr", // Use stderr to keep stdout clean
)
defer logger.Shutdown()
logger.Info("This goes to both file and stderr")
```
**Dynamic configuration** (toggle at runtime):
```go
// Start with file-only logging
logger := log.NewLogger()
cfg := config.New()
cfg.Load("app.toml", os.Args[1:])
logger.Init(cfg, "logging")
// Later, enable console output dynamically
cfg.Set("logging.enable_stdout", true)
logger.Init(cfg, "logging") // Reconfigure
// Or disable file output
cfg.Set("logging.disable_file", true)
logger.Init(cfg, "logging") // Now console-only
```
## Implementation Details
- **Lock-Free Hot Path:** Logging methods (`l.Info`, `l.Debug`, etc.) operate without locks, using atomic operations to
