Clojurians Log v2

Hmm. I wonder if there is a way to execute (System/setProperty "foo" "bar") as part of a leiningen build right from project.clj

And naturally this should affect the actual application JVM instance, not the leiningen one

Use case: I need to set the Timbre logging level before any application code executes. When using Figwheel Main with Timbre and it's slf4j adapter, it sets the logging level to DEBUG and this causes Jetty (used by Figwheel Main) to log it's stuff at that level. And that causes a TON of unnecessary crap to fill my logs

Also, since in this case it's Figwheel Main being called I do not have a proper place where I could inject that system property value before Figwheel starts it's magic

just as a temporary work around, have you seen that you can change the figwheel logging level?

Yeah

Unfortunately doesn't affect this

ah bummer. was hoping for an easy fix for you 🙂

The problem here is that Figwheel Main logging level is a jucl -level config

It's actually quite strange, Figwheel Main uses jucl, but Jetty uses slf4j

So, if one changes jucl level logging level it really doesn't help at all

i'm not following the term jucl

sorry, wrong abbreviation. The Java Commons Logging or whatever. The one which comes with Java

ah ok.

Which NO ONE uses

😄

I can see why it was chosen, no extra dependencies

ah. java.util.logging

indeed

But if one grabs pretty much any java lib you'll get either log4j or slf4j

All of these sucks monkeyballs, I like Timbre

But in this specific case I'm pulling my hair out with this combo

I could set an environment variable to control Timbre before I even start Leiningen

But that unfortunately is not a very good solution since that doesn't work as part of the build

One can also control Timbre via system properties but that too isn't that easy to control with Leiningen which uses a separate process model for builds

It's frustrating that I've spent 5 hours now in a futile attempt to silence Jetty logging when making a figwheel build with leiningen

Decided this is a Figwheel Main issue and created one https://github.com/bhauman/figwheel-main/issues/162
