Just want to emphasize this because clojure is indeed a small, lesser known language that has a hard enough time attracting users. This is not what anyone would consider an idiomatic example of using clojure.
And there isn't anything especially wrong with sticking to Java primitives if someone is comfortable with them. They work fine for Java programmers. The dude doesn't need to learn a new async library to write an LSP client if he doesn't feel like it. Code works, its easy to read, easy to understand and modify.
Then there's other things to consider, like the fact that this LSP client, while succinct, pays not only the cost of loading Jackson, but also the cost of loading clojure.core, which is quite non-trivial[3]. Startup time for LSP servers and clients definitely matters to some, considering that e.g. even clojure-lsp recommends running native executables over JAR files[4]. Can't find documentation proving it's for quick startup, but it's a plausible rationale for their recommendation of a binary over a JAR.
Note: I have used Clojure professionally and in hobby projects. I think it's nice that one can interactively develop a minimal LSP client and the resulting amount of work is roughly 200 lines of code. I say "minimal" because it's unclear how this client deals with offsets reported by LSP servers, which are all given as offsets in a UTF-16 encoded string. In any case, I still think advertising "LSP client in 200 lines of code" hides valuable information regarding functionality, implementation, "actual" code size, and trade-offs made in the choice of technology stack.

For very good reasons.
> It’s so verbose and complex for what it is doing. ... and using core.async
I think this code is actually quite straightforward and easy for a clojure developer to understand. In fact, using core.async in this case would be overkill and could complicate things further.
I'm curious to see your core.async-based version :)

But I don't feel like the world particularly needs to hear my singleton exclamations, no reason to add unnecessary noise, this isn't reddit.

I now want to hear more as to why Defold now has a clojure repl! I noticed some musings around some native bindings in gh issues which is "interesting" but I'm not quite getting it. I guess off to the forums I go!

I don't know why it would feel comforting to people that languages like python/c++/rust keep piling on syntax and features like the people in Rammstein's keine lust, who keep stuffing themselves in spite of their grotesque size.
Haven't looked at jank, but given it looks like lisp, it would be the same thing. No news is actually good news in some cases

If only other languages could just have been designed perfectly first try like <insert your favourite irrelevant lisp dialect>...

Maybe you are simply ignorant of how many systems might actually run a lisp or similar "irrelevant" programming language in the systems you interact with. From airline reservation systems to banking and high-frequency trading.
JavaScript is not, in fact, eating the world, and nor will Python, Rust or whatever else.

is it really though? While I feel the hype is definitely not what it used to be, after getting back into Clojure after a few year hiatus I'm not noticing anything that would suggest it's dying. For example, there's still active Clojure podcasts still in production. Jank may very start exceeding Clojure in terms of hype though.

Languages are often thought of in-coupling with the runtime.
But Clojure is a way of writing code. The official implementation runs on JVM. There are community ports for Node, C#, Go. Jank is the port on CPP.
Jank winning is Clojure winning.
