Question about the general mental model

[jackkoenig]

I really like scribe, but I find it difficult to wrap my head around how the API is supposed to work sometimes.

For example, given the following:

    val logger: Logger = scribe.Logger.root.clearHandlers().withHandler(minimumLevel = Some(Level.Debug))
    logger.warn("Warn")
    logger.info("Info")
    logger.debug("Debug")

I would assume the logger.debug statement would print, but it does not. Instead I have to also .clearModifiers(), then it works.

val logger: Logger = scribe.Logger.root.clearHandlers().clearModifiers().withHandler(minimumLevel = Some(Level.Debug))

I've searched through the Wiki, but I haven't found an explanation that helps me internalize why this is.

Any tips or pointers?

It's understandable. If you were doing this with anything but Logger.root, this wouldn't be an issue, but the root logger gets configured by default like:

    root
      .orphan()
      .clearModifiers()
      .withMinimumLevel(DefaultRootMinimumLevel)
      .clearHandlers()
      .withHandler()
      .replace(Some("root"))

The withMinimumLevel sets a modifier that has to be cleared.

Sorry for the late reply, I haven't been paying much attention to GH.

Thank you for your response.

Even with that, my expectation would be that a .withHandler(minimumLevel = Some(Level.Debug)) executing after that .withMinimumLevel(DefaultRootMinimumLevel) would override the value, like doing a copy on a case class.

The reason is that the minimumLevel on a handler is optional, so if it's not set it will log everything. This is why the modifier exists so any handlers added inherit the minimum level filtering.
