Regarding calling Clojure **from** Java... I saw a Stuart Halloway tweet responding to someone who'd found this a "soul-crushing, miserable experience."
I had a similar miserable experience and figured it was just me, but am now suspecting that's not the case. (Happy to be shown the light however.) Stuart H posted https://github.com/stuarthalloway/clojure-from-java to demonstrate the ease of Java consuming Clojure, but I find it far more important to be able to *compile* Java against Clojure interfaces not invoke it dynamically from Java....because dynamic invocation from Java is unwieldy to the point of it being a likely deal breaker for any Java shop. Dynamically loading classes and invoking methods.... c'mon, no one's going to ask their Java devs to do this. If Clojure doesn't have a good compile-time consumption story for Java consumers, I think that's a loss. (Even if it is just providing better docs or archetype/bootstrap examples in this regard.) Because otherwise Java code bases around the world could be eaten away by (compiled) Clojure from the inside out, giving Java dev teams enough time to be overtaken by the miracle that is Clojure. Inspired by Stuart's example, I was successful in putting together a quick build to achieve this ideal: https://github.com/atdixon/clojure-from-java However, I have a few open questions: - when I tried to AOT only the public-facing clojure code that I needed to compile against, I found out at runtime that this wasn't going to work. Dynamic clojure code was loading my same types into DynamicClassLoader and when my statically-compiled, root-class-loaded code was getting executed the ClassCastExceptions of course were flying. So am I right to think that you have to AOT everything in order to do this right? - IDE support (for me, Cursive) "works" but is non-ideal; you have to manually compile the dependee/Clojure jar, then Cursive will let you execute Java code against the manually aot-compiled Clojure code - AOT producing generics/generic types doens't seem to be part of any of this... is this a lacuna in the Clojure AOT space, are there libs that can help here? This story ^^, if made easier, seems to me would boost Clojure adoption in Java/JVM shops.
