for clojure code that throws using ex-info how do people tend to differentiate different errors when matching with catch statements?

I'm using hikari-cp with Postgresql and it's creating a ton of logs in my repl.. how can I change this?

@clarkenciel You can catch Exception or clojure.lang.ExceptionInfo and then use ex-data to get the payload and process it however you want.

With ring/jetty I use jetty-logging.properties file.. there must be an analog for postgres/jdbc?

@thiru0130 Much will demand on how you're dealing with logging overall.

We use Timbre and the adapters that route all the Java logging through Timbre, so we can control the logging level in one place.

I don't know what hikari-cp uses for logging... I suspect you're dealing with Java-level logging tho', rather than a Clojure issue 🙂

Oh that's nice.. I should probably set that up

Yea.. Java level

Maybe put a logging.properties on your classpath...

Ah, here you go: https://stackoverflow.com/questions/37035229/how-do-i-set-the-logging-level-for-hikaricp

You might be able to put that level setting in logging.properties rather than as a JVM option...

Hmm the logging.properties file didn't seem to work

I'm guess I can pass along the JVM option when using clj?

Yup, with -J or via a :jvm-opts alias with -O...

Ah yes it works!

Thank you @seancorfield - you are awesome!

I'm just quick with Bing 🙂

Even more impressive that you're using a lesser search engine! 😉

jk.. I have no bias myself

Meh, I switched from Google to Bing years ago and I actually find it to be way more accurate and useful than Google...

(I've been an Apple guy since the early 90's but lately I've been very impressed with MS and very not impressed with Apple -- I run Bing, Edge, Outlook, and Cortana on my iPhone 🙂 )

Really? I'll have to give Bing a go then.. I've tried using http://duckduckgo.com several times but always ended up going back to google

so for getting started in clojure on a mac again, is java 11 fully supported these days? or is that going to be a pain point? also does using the oracle jdk (https://www.oracle.com/technetwork/java/javase/downloads/jdk11-downloads-5066655.html) vs openjdk (https://jdk.java.net/11/) make a significant difference? thx!

afaik "clojure tries to be 2 versions behind"

I personally am using Java 10 with no issues though

There are some minor issues, which resolved in the upcoming Clojure 1.10

Is there any reason to choose clj-http over clj-http-lite if the latter has all the necessary features?

@djz If you're looking to use Java 11, you should read this https://blog.joda.org/2018/09/do-not-fall-into-oracles-java-11-trap.html

@seancorfield @alexmiller & @coinedtalk thanks for the insights!

@seancorfield wow, that was pretty sobering... tl;dr = use openjdk 🙂

Yeah, that's about the bottom line. Unless you want Oracle's paid support 🙂

kind of a weird question - is there a way i can stash a value to inspect later in the repl? I have a ring request map (and afaik, no step-through debugger on the command line?), so it would be cool to somehow say "Store this value in that global name to inspect in the repl after the request"

now that i type that out, i could swap it into some atom in my-app.debug or somesuch?

you can use a standard def from within a function that processes the ring request

Then call some.ns/whatever-def from the repl

yeah, awesome, thanks @dadair - i'd still kill for a step-through debugger in the repl though (like python's pdb)

There’s a library called scope-capture that might get you further along that direction

nice! i'll give it a shot

thanks
