In terms of debugging cljs, I've always used chrome over firefox. However, I'm not sure if there is an advantage or if it's just a personal preference. Is either browser 'blessed' by cljs ?

i think chrome has the best devtools by some margin

Erlang has something called ETS (erlang term storage). What is the closest thing Clojure has? spit/slurp of edn ?

Atoms kinda, unless you mean mnesia

Even then it s quite different

maybe ETS is not what I want -- I want the one that serializes to disk.

sorry, I meant http://erlang.org/doc/man/dets.html

Dets is way more advanced/high level

Slurp/spit is basically writing a term to file and using consult to read it

They aren't. If I AOT compile, then I do get the wrong one. Curious. 🙂

Any news on the ClojureSync conference videos? I am curious to watch the talk by Gerald Jay Sussman.

https://github.com/fusesource/rocksdbjni vs https://mvnrepository.com/artifact/org.rocksdb/rocksdbjni/3.5.1 <-- anyone know which works better for clojure <-> rocksdb ?

What is the simplest way to do string -> byte-array?

(.getBytes s)

any clojure veterans got any insights what could cause java.lang.NoClassDefFoundError: Could not initialize class shadow.cljs.devtools.server.reload_classpath$process_update$fn__65735?

its a normal clojure ns which doesn't do any weird trickery https://github.com/thheller/shadow-cljs/blob/master/src/main/shadow/cljs/devtools/server/reload_classpath.clj

no AOT or anything involved

Is it referring to the #(... %) on 41 or 51 ?

appears to be tools.namespace related

This is clearly beyond my knowledge of clj. sorry.

@thheller I tend to have this sort of error after I uberjar my project while my code is running. I think this changes the class files in some way to messes up the REPL.

I have a project, wherein I want to include a single jar and push it with my lib. Is there a way to include that in my project.clj without doing a local mvn install? And if its a local, does it get pushed in the jar going to clojars?

@laujensen you can do a lein install to install a jar just to your local repo.

Has anyone here used pact for testing in clojure?

Hi all; for those using Logstash, I've created an EDN filter plugin and published it to rubygems https://rubygems.org/gems/logstash-filter-edn

You can use this in much the same way you'd use logstash-filter-json. I'm using it to parse EDN embedded inside log messages.

Poll: how many of you are using clojure with java 9 (or 10)?

According to http://blog.cognitect.com/blog/2017/1/31/clojure-2018-results "Uptake of Java 1.9, released last year, has been a bit slower with only 29% adopting Java 1.9 so far and 88% of developers using Java 1.8. Only 6% of developers are using Java 1.7 and less than 1% are still using Java 1.6."

I’ve done a bit with Clojure and Java 10 btw and haven’t seen any issues yet

there is one fragile test case that was broken by serialversion uuids changing in java 10 and that prevents Clojure’s own test suite from passing, but this is a flaw in the test, not an issue in Clojure

Can anyone explain these new features for clojure 1.10? What’s the plan for prepl? And what are taps for?

https://github.com/clojure/clojure/commit/86a158d0e0718f5c93f9f2bb71e26bc794e7d58e

there will be more info in the future, we haven’t officially released any of that yet

prepl is a programmatic stream-oriented remoteable repl, primarily useful for tooling

taps are a debugging aid to allow you to “log” a message at any point in your app and listen elsewhere. prepl supports remoting the debug tap over the wire as a side-channel

Sounds like Erlang tracing. Are there filtering capabilities ?

No, other than applying any function you like when reading the tap

interesting…

prepl sounds similar to @cgrand’s unrepl
