Seems so:

$ bb -e 'java.util.concurrent.ConcurrentHashMap'

If you can explain what you're using it for, we could consider adding it

Porting over this fn: https://github.com/clj-commons/manifold/blob/37658e91f836047a630586a909a2e22debfbbfc6/src/manifold/utils.clj#L77

As according to my measurements, satisfies? also suffers from relatively poor performance in bb not only clj

This implementation won't work in bb as protocols are implemented entirely differently

But if theres an alternative class I could use I don't insist on concurrenthashmap

Ah okay, that settles it then

Oh I see it's only using memoization, then it should be good actually

Oh

Well maybe you can use a regular java util HashMap with locking?

I think adding the class is almost a no-brainer though, feel free to post an issue

Cool, thank you

I'll try the locking route though

There is also (babashka.process/exec ["bb" "(+ 1 2 3)"])

This does a true exec call, leaving the parent bb

Thank you

Hmm. Insert println ?

I'll have to load it from source rather than using maven

yes, I would do that if you want to debug. Sorry to hear about your problem though

May I refer you to our bb bible? :) https://book.babashka.org/#_reader_conditionals

ah! I was perusing the docs dir in the repo

thanks

I already opened one for clojure.lang.MapEntry/create. I just found an interface, clojure.lang.IKVReduce/reducekv that doesn't seem to exist

In bb it's usually not worth it using those internal clojure.lang stuff - just using the core functions is likely faster

ok

unless we start heavily optimizing interop - which is on the TODO list

but interop in bb is quite slow compared to pre-compiled stuff

gotcha

if I'm going to add a bunch of reader conds to my lib for bb, is there an easy way to run my tests in CI using bb?

I'm using kaocha for CLJ and CLJS

I guess mainly looking for a good example

The cognitect test runner is compatible with bb if you add the bb fork of tools.namespace to your project: https://github.com/babashka/tools.namespace

But you can also just make a runner namespace: https://github.com/metosin/malli/blob/master/test/bb_test_runner.clj

cool, just what I needed! thanks

For comparison:

$ bb -e '(time (dotimes [i 10000000] (first {:a 1})))'
"Elapsed time: 998.372221 msecs"

$ bb -e '(time (dotimes [i 10000000] (clojure.lang.MapEntry. :a 1)))'
"Elapsed time: 4668.442018 msecs"

Currently interop is done using reflection and we could cache some things here and there to make it faster, or special-case some stuff

oh wow
