Level handling is non-obvious

[nhi-vanye]

On every logging system I've used across many languages if you set the log level to be Info, you also get Warning, Error, Fatal etc.

Not so with slog.

If I do handler.NewConsoleHandler(slog.Levels{slog.InfoLevel}) I just get Info messages...

So I'm expected to build by own list ? That's really annoying to do programmatically for no value that I can see...

hi @nhi-vanye

There are two ways to limit the log level to be recorded in slog:

1. Use []level to restrict logging to specified level logs
2. Use max level to limit the maximum log level

In the next version, I will provide some convenient methods to quickly use two methods:

// limit max log level, will log: panic ~ info level logs
h := handler.ConsoleWithLevel(slog.Info)

---

functions:

// ConsoleWithLevel create new ConsoleHandler and with max log level
func ConsoleWithLevel(level slog.Level) *ConsoleHandler

// ConsoleWithLevels create new ConsoleHandler and with limited log levels
func ConsoleWithLevels(levels []slog.Level) *ConsoleHandler

Thank you for very quick response.

I might consider changing the name to be ConsoleWithMaxLevel() to more closely match the behaviour as I think there's a good use-case for a corresponding ConsoleWithMinLevel(). That would make it very easy to separate production from debug logs with multiple handlers off a single Logger...
