log4dotty's Issues

question about by name passing vs macros in logger implementation

Hi,

I read your blog post
https://heikoseeberger.rocks/2019/06/19/2019-06-19-dotty-1/

I'm trying to contribute some code to the scala-logging
lightbend-labs/scala-logging#212
but encountered many issues arising from the usage of macros, and i was wondering why use macros here at all, instead of by-name parameter passing, as you explore in this repo.

i'm assuming the cause is due to callsite information being lost if you can't inline (via macros in scala2 or inline via new features in scala3),
but apparently, for example in logback, this can be configured in the pattern layout encoder (as i mention in my PR), so not sure if this is a big deal?

I'm asking because i'm thinking of creating a new logger library,
with a scala 2 version that works via by-name parameter passing, and possibly a scala 3 compatible version that may or may not use inline features.

Would appreciate your feedback,
Thanks!
