This is excatly what i am trying to do but when it's set to true it does not have color anymore ^^

this does not color the logs ! when i desactivate withJansi they are colored back

It looks like you need to use their highlight and not your custom one.

i tried... no with theyr highlight it does not work too

It worked fine for me; however, I did have to run it in a regular terminal rather than within IntelliJ's run config (in my case). This what I ran to test the changes:

./gradlew installDist
build/install/mc-image-helper/bin/mc-image-helper install-curseforge --output-directory=/tmp/cf --slug=prominence-2-classic

and this is what I have for the pattern:

            <pattern>%highlight([mc-image-helper] %d{HH:mm:ss.SSS} %-5level : %msg%n)</pattern>

...and just now added a "test-logging-level" subcommand to further confirm things:

okay but outside of intellIj terminal right ?

I'm running the above commands from IntelliJ Terminal window, but not via the Gradle/app run config

Okay nice it works for me ! Can you confirm it works with the custom hilight ( so the warnings are yellow) ?

I don't want to use custom highlighting if their built-in works -- besides yours is still missing the is-terminal conditional. I would prefer to have it not match colors than reinvent their wheel.

as you want. But i do not reinvent their wheel, i just customize the colors of the highlight --

I can't see that they're conditionalizing either, so I'm fine with your custom one then

Double checked theirs at
