is there a babashka equivalent of this code? 

user=> (mapv :name (filter (comp :public :flags) (:members (clojure.reflect/reflect d))))
Could not resolve symbol: clojure.reflect/reflect [at <repl>]
user=> (require 'clojure.reflect)
java.lang.Exception: Could not find namespace: clojure.reflect. [at <repl>:10:1]

Jeffrey Bay14:08:08

i'm trying to get the functions/methods available on an object, but babashka doesn't seem to have clojure.reflect available?

borkdude14:08:02

Currently not exposed, but I think we're already using this somewhere internally so we could probably just expose it without growing the binary. Worth posting an issue for

borkdude15:08:49

If you want, you could try a PR. When this is added, I'll check the binary size difference.

i’m trying to load lanterna w/ (pods/load-pod 'org.babashka/lanterna "0.0.1-SNAPSHOT") and it looks like it’s not finding the artifact (https://14-303520083-gh.circle-artifacts.com/0/release/pod-babashka-lanterna-0.0.1-SNAPSHOT-macos-amd64.zip), anything I can do to help publish that?

borkdude18:08:02

@U0AQ1R7FG I'll retrigger a build

@U04V15CAJ sweet, thank you! 🙏

bb supposes to be quick startup. However, in one of my windows machine, it is slow. Here are the measurement. Any suggestions about what to do?

the latter doesn't start a jvm so I'm not sure it's a very useful comparison point

Alex Miller (Clojure team)19:08:04

I'm not sure what the former does exactly but the latter will just be some bash that echoes via cat

borkdude20:08:19

Continuing in thread @jeff66ruan , @alexmiller :

borkdude20:08:06

bb does run a JVM to calculate deps from bb.edn (if present) so if you run bb for the first time, it might take a second, the second time there will be no JVM invocation because of caching. So be sure to either run bb from a directory that has no bb.edn or run it a second time.

JeffR02:08:05

I created a new folder so no bb.edn in the current path. Here is running data. there are a few ran quick but others not.

@jeff66ruan How did you install bb?

borkdude10:08:33

And which version?

borkdude10:08:47

Ah I see that some invocations are fast: Milliseconds : 61 Not sure what's going on with your machine, but could it be a virus scanner? I've found this to be the answer several times on Windows ;)

JeffR20:08:48

@U04V15CAJ It is the scanner! bb can always run fast after I turned the scanner off. Thanks!
