When using slf4j (or other) loggers, do you use
1️⃣ string interpolation - <http://logger.info|logger.info>("the value is $value")
2️⃣ passing additional arguments - <http://logger.info|logger.info>("the value is {}", value)
3️⃣ 🧵 something else?

"... {}" for logs that need to be removed by R8

[Matteo Mirk]

2️⃣ is the intended way, it guarantees that the message won’t be interpolated if the corresponding level is not active

[christophsturm]

kotlin logging: logger.debug { "hello $message" }

[christophsturm]

imo even better than 2

[arekolek]

logger.debug { "hello $message" }

I'm not sure what ☝️ is, something you defined on your own?

#kotlin-logging

[dave08]

It's a library

Have you considered using structured logging, then no string interpolation is required...
