Thank you for the explanation. What if I target a non-OO-centric VM (like Parrot or LLVM)? I've noticed that most Lisp implementations define lambda calculus primitives, and then use those as the core. I wonder what would be if we had bytecode primitives, and defined everything else on top of th

Re: Update

The JVM is very class-oriented. It is basically designed for Java, and corresponds pretty much to the things you can do in Java. Code belongs to methods which belong to classes, and calls are made using java method calling conventions. Data has to be stored in primitives, arrays, or objects; and

Re: Update

Well, why write it in primitives when there is a perfectly good compiler from java to primitives? I dont quite understand why you think there would be benefit from manually writing everything with java bytecode. The JVM works with classes, thats how its designed, Clojure itself is just a java l

Re: Update

Why are Clojure features defined in terms of Java classes, instead of as bytecode primitives? For eg: Cons is a class containing two objects: first and rest. Is this only to achieve Java interoperability, or is there more to it? -- You received this message because you are subscribed to the Goog

Jasmin would be a much better choice, btw, because it could be used as a dependency in Clojure. -- You received this message because you are subscribed to the Google Groups "Clojure" group. To post to this group, send email to clojure@googlegroups.com Note that posts from new members are moderat

---IDEA--- I was wondering if we could have a bytecode DSL that would map directly to JVM assembler, using either Jasmin or Krakatau . Then we could define primitives using these bytecode instructions. For eg: (defroutine

Hi, thanks a lot! I ended putting the question in StackOverflow, yesterday, and also got this answer. It would have took a while until I came up with this. But now I understand. For my concrete case I needed to update the record with all fields passed in a map. So I did: (commute items

Re: How do I update a record in a vector, matching certain criteria?

My response had the assumption that this is an example of an X-Y problem :-). If you want to literally do what you said, then you can't use update-in because the value at that point is a seq. If you have to continue in this way, for some reason, what you probably want is map-indexed,
