Clojurians Log v2

I still need to port immutable data structures, but the fact that it manages to compile all of sci and run it is pretty cool

does it also pass all of the tests? ;)

perhaps SCI could even support janet, but I don't know how much of a stretch that is. I don't know janet very well and don't know if it's close enough to clojure to do it with reader conditionals

yeah looks like the tests pass

I also wanted to support ClojureDart, to build a phone app where you could evaluate some CLJD in a phone app, sound like fun

it's still very raw though, so bugs are definitely there 🙂

thinking about this too, might actually be useful to have immutable data structures as a compile time toggle

oh and I just kind of assumed ClojureDart was already using sci

why did you think?

since sci is already fairly self contained it seems like an obvious choice if you're porting Clojure to a new runtime no?

there is edamame layer which I did have to shim, but that was pretty small

well SCI is an interpreter, ClojureDart isn't an interpreter but a compiler

that's true, I guess just taking cljs directly makes more sense there

cljs?

wouldn't you want to reuse most of the implementation?

does ClojureDart just do everything from scratch?

I don't know

Pretty cool! Is it possible to call a Janet function from Clojure code?

(Also, there is a #C015LCR9MHD channel too.)

without looking at the code, this should work since it's explicitly tested in SCI

oh yeah I missed the sci channel, and yeah calling Janet code should work, I'll add explicit interop there

What's your use case? 🤔

I'm using Janet as the plugin system here https://github.com/dirge-code/dirge so I was thinking I could get full blown Clojure here relatively easily

Janet is nice, but it's just different enough to trip me up 🙂

maybe jank would also work? not sure if C++ and Rust stuff mixes well, but .. probably?

I did look at it, but the runtime would be pretty chunky compared to Janet, and the build pipeline would also be more complex

Jank is great, but Janet is a lot more compact and easier to embed, also has a Rust wrapper already as well

there's a bunch of go clojure dialects now too. maybe also easy to embed. I just saw a post in #C8NUSGWG6 where the author embeds let-go on a remarkable 2 android device

yeah I've been following that a bit, let-go definitely seems neat, and honestly I regret going with Rust over go for my tool, compilation times get absolutely brutal once you get to 100k loc or so

it takes minutes on my machine, so any time I want to do something like a UI change where I need to test and see how it feels, it's a few minutes of waiting for the build

but jolt is mostly just to play around to be honest, Janet works well already

100k lines ... that's how much Clojure we had with a team of 4 devs of 5 years of writing :)

yeah you can produce a ridiculous amount of code once you have LLMs in the loop 🙂

to be fair Clojure is a lot more compact than Rust

but it's still a chunk of code to be sure

I'm guessing no because there is no mention of it on http://book.babashka.org but I thought I'd ask

no, but there is BABASHKA_PRELUDE which is a code snippets that is invoked on each bb invocation, would that help?

I don't think so, I want to pass -.ssl.trustStore=$JAVA_HOME/lib/security/cacerts 😛

does setting the system property work?

in BABASHKA_PRELUDE

I suppose I could set the property in code yeah

let me try

that particular bit of command line handling is done by graal, babashka can't even access it.

I'm wondering if there is a GRAAL env var then...

you can see all the available options by following the bb command line

thank you

Substrate VM opts:

  -D<property>=<value>     Set a system property (e.g. -Dx.y=99).
  -Xmx<size>[g|G|m|M|k|K]  Set a maximum heap size (e.g. -Xmx256M to limit the heap to 256MB).
  -XX:PrintFlags=          Print all Substrate VM options.

I guess you could make a bb wrapper bash script on your system

which does exec bb -D... &?args

(pseudo-bash)

yeah, that could also work

looks like BABASHKA_PRELOADS isn't processed early enough for my usecase Exception in thread "main" java.lang.Exception: Error: Cannot download Clojure tools. Please download manually...

I'll go with the wrapper 🙂

wait, this is deps.clj

that should be affect by CLJ_JVM_OPTS

try that

we specifically support that. https://github.com/borkdude/deps.clj/commit/4417bb69a665a6787e3c05b0ab94a3620510fb62

ah

let me try

if it doesn't work, I consider it a bug

that works!

CLJ_JVM_OPTS only affects deps.clj and not the bb process that comes after, right?

correct

the process that downloads the tools jar is a clojure process at the moment

eh no

but it is a separate process

thank you sir

I've yet to get to the point where I can verify the PRELOADS thing but I'll signal back

👍

let me try and create a minimal repro

bb -e '(with-redefs [org.httpkit.client/get (fn [] :foo)] (org.httpkit.client/get))'

can you find one commit that could be related to this change? doesn't ring a bell to me directly

you can bisect with clojure -M:babashka/dev ... if you check out bb including submodules and make the right dev alias (can copy paste that here if you want)

this looks sus https://github.com/babashka/babashka/commit/96c4d58f4d8f12b0ac41638d705d28583fcf4bdf

issue welcome

(I haven't bisected it, just had a spot check through the commits)

yeah that may be it

not sure, but I'll find it

Thank you! I created https://github.com/babashka/babashka/issues/1979
