TIL about guest language support in native-image:
> Native Image supports JVM-based languages, e.g., Java, Scala, Clojure, Kotlin. The resulting image can, optionally, execute dynamic languages like JavaScript, Ruby, R or Python. Polyglot embeddings can also be compiled ahead-of-time. To inform native-image of a guest language used by an application, specify --language:<languageId> for each guest language (e.g., --language:js).
> – from https://www.graalvm.org/22.0/reference-manual/native-image/
Has anyone here used this already?

tried this out naively with clerk (https://github.com/nextjournal/clerk/tree/native-image) but https://gist.github.com/mk/f6b043ada640904abe4d3ed215fd75b5 around com.oracle.truffle.js.runtime.JSRealm.random.

I've played around with this, e.g. embedding JS in bb, it works. But what doesn't work well, or at least, at the time, was pre-warming a context so it would start faster

If you're trying to compile the CLJS compiler to native: this might work to some degree (in theory, I've never seen it work in practice), but macroexpansion has a problem since it relies on clojure.core/eval

use case would just be our js markdown parser for now
mkvlr 2023-01-03T14:54:41.230369Z
where we could also go down the quickjs route
borkdude 2023-01-03T15:19:25.413859Z
right, so you want a binary to shell out to for markdown?

would need to include sci / bb to be actually useful
