Clojurians Log v2
beginners
Google AI seems to indicate a number of ways to change the logging level. Some of the ways are from configuration files, and some require Clojure code early in the load process. It seems unclear that an obvious mechanism exists, since many of the solutions seem to look at the specific package used for logging for your application. -- To change the log level when starting a Clojure application that uses clojure.tools.logging, the approach depends on the underlying Java logging framework being used (e.g., Logback, Log4j, java.util.logging). 1. Configure the Logging Framework: • Logback: If Logback is the underlying framework (often the default in many Clojure projects), the log level is typically configured in a logback.xml file located on the classpath. You can modify this file to set the desired log level for specific loggers or the root logger.
# Example log4j.properties snippet for setting root log level to DEBUG
log4j.rootLogger=DEBUG, console
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=%-5p %c: %m%n
you've copy pasted a bunch of AI generated nonsense without any clear question or goal. maybe start with a clear statement of your problem or goal if you need help
Sorry, all, for the noise. I was trying to answer a previous, unanswered question. I failed.
I'm not too fond of AI responses on Slack myself; if I wanted an AI's opinion I would ask it directly. If I'm addressing a chatroom of what I expect to be people, it's because I want people answers. That being said, if you believe there is value in an AI's response to a specific question someone else has posted, it's a better approach to post that answer in the thread of that question, rather than in the channel itself.
If you want to use AI, it'd be a better approach to ask it privately, read its answer, test it, and then come back to Slack with a human-written summary of the findings, rather than copy/pasting the whole AI answer directly.
Oh, this thread makes me feel better. For a minute I thought you had an AI bot in here.

How do I change the log level for (say) starting clj. For example, I would like to see the debug output from io.pedestal.http.cors/allow-origin when I am experimenting with it in the REPL.
there'll need to be a logging library on the classpath, and depending on which logger is in use, there will typically be multiple ways to change the log level (file-based config, JVM properties, sometimes environment variables)<https://pedestal.io/pedestal/0.7/reference/logging.html#_example_logback_test_xml> is an example that turns on debug
If you're using logback the https://github.com/pyr/unilog library is great for changing config at runtime
https://practical.li/clojure-web-services/service-repl-workflow/mulog-events/ which has https://github.com/BrunoBonacci/mulog?tab=readme-ov-file#motivation. Its also much simpler to filter the log output when logging a structured event.
