plogr
go-logr implementation with pterm
Usage
See examples
Add more colors and levels
By default, only level 0 (info) and level 1 (debug) are supported.
While go-logr doesn't have names for logging levels ("info", "warning", etc), pterm does. Both libraries agree that verbosity is increased with higher numeric logging level. For pterm however, one could argue that their "Warning" and "Success" levels have lower verbosity than "Info". If you like to customize the levels or styling, you could do something like this:
func main() {
sink := plogr.NewPtermSink()
sink.LevelPrinters[3] = pterm.Debug
sink.LevelPrinters[2] = plogr.DefaultLevelPrinters[0]
sink.LevelPrinters[1] = pterm.Success
sink.LevelPrinters[0] = pterm.Warning
logger := logr.New(sink)
logger.V(0).WithName("main").Info("Warning message")
logger.V(1).WithName("app").Info("Success message")
logger.V(2).WithName("database").Info("Info message", "key", "value")
logger.V(3).WithName("controller").Info("Debug message")
}
That means whenever you want to show informational messages, you'd have to set the logging level to 2 in your code base.
Alternatively, without breaking the code base, append levels like success to the LevelPrinters to your desired level, disregarding the verbosity increase though.
The error printer can be customized as well, but it has its own field.
