log4k's Issues

Create FileLogger

Requirements

Should avoid dependencies on ktor-io or kotlinx-datetime
Available for JVM, Android and iOS at least
- Not sure what file could mean in a browser context
Should allow to rotate logs
- Daily
- Every X lines logged

Usage Draft

Log.loggers += FileLogger(logDir = "my/logs", rotation = Rotate.After(lines = 4096))

Any plans to support lazy evaluation of log messages?

Sometimes log messages use string interpolation that call "expensive" functions to compose the final string. Commonly, log frameworks offer an API that takes the message as a lambda in that case (like Log.info { "Did ${compute()} things." }), so string interpolation only happens if the respective log level is active. Is something like that also planned for Log4k?
