Logger package was inspired by asterisk PBX logger.
- Logger implements context.Context interface, which allow easy use it as logger and/or as Context
- Common/separate settings for each Logger instance
- Auto/manual increment for "transaction" like based on prefix
- Supported output formats plain and json
- Colored output for plain logs (journalctl -a)
- Separate Logger instance with cancel (cancel() freeing Logger recources):
import "github.com/microgiantya/logger"
...
ctx, cancel := logger.NewLoggerWithCancel(&LoggerInitParams{
Severity: 7,
})
defer cancel()- Separate Logger instance (Close() freeing Logger recources):
import "github.com/microgiantya/logger"
...
ctx := logger.NewLogger(&LoggerInitParams{
Severity: 7,
})
defer ctx.Close()- Plain output:
...
ctx := NewLogger(&LoggerInitParams{
Severity: 7,
UniqueIDPrefix: "apiV1",
})
