Re: Advice on introducing a Java dev to Clojure

Hi Johanna, You could try the angle that a Clojure REPL is a practical adjunct to standard Java tooling, particularly if the developer is using IntelliJ since Cursive is extremely accessible. I wrote something along these lines: http://derek.troywest.com/articles/proximity-and-brevity. T

Hello all, dali is a Clojure library for representing the SVG graphics format. It allows the creation and manipulation of SVG files. The syntax used to describe the graphical elements is based on hiccup

Re: Scripting with Clojure / "slow" boot time

Based on the responses, many people are seeing slow times with "lein repl", which is generally *much* slower than just starting a normal Clojure repl with clojure.main. If you want to compare, you can use lein to dump your classpath to a file (or the Windows equivalent of these): lein classp

conditional logic implemented as pattern-matching and restructuring in the signature of the function

It's not pattern matching, but would replacing the apply with a reduce achieve the same result? I'm not in a position to test this right now, but I believe (reduce f init ()) returns init without invoking f, and (conj x a b c) is equivalent to (reduce conj x [a b c]), so replacing apply with reduc

Re: Scripting with Clojure / "slow" boot time

Personally, I've recently fought machine-specific AOT breakage issues by forcing maven-clojure-plugin to only compile a single entry-point namespace, making compilation order deterministic again. Arguably, it should have worked in any order but this specific issue was hard to track down. In any c

Re: Scripting with Clojure / "slow" boot time

Parallel loading is something I've looked at a little bit. Unfortunately theory is easier in theory than in practice. :) While in many cases, it probably works fine, it's possible for there to be problematic ambiguity with which namespace is loaded first, especially for things that update state

Ah, I see that part of the reason it’s not yet documented is that it’s not really finished; you can’t, for example, use a keyword as a function with it. Trying to use #=(:tap-tempo control-buttons) as a case target fails with clojure.lang.Keyword cannot be cast to clojure.lang.Symbol. I guess I

Re: Java Interop for a static method call that returns an ArrayList

Thanks a million Gary, this has been extremely helpful. I'm from an object oriented background and I'm having the usual problems of crossing into the functional thinking land, hence the straightforward question. I appreciate the help, it worked exactly as you've outlined below, Thanks, Adrian.

Lazy var loading is one of the things we're looking at. There is some work on this early in the "direct" branch (although at this point it's pretty out of sync with current code). On Wednesday, February 10, 2016 at 2:22:12 AM UTC-6, Mikera wrote: > > Good initiative, I've filled in a response t

Re: Can the data in a vector have data inside it that points to the same vector? vector1=[a b c d] a=[1 2 f s vector1]

Basically, since vectors are immutable, you cannot easily construct that kind of recursive structure. Any means of breaking immutability would allow it, though (atoms, promises, undocumented mutable apis, mutable objects inside the vector, etc.). To clarify: the vector itself does not explicitly p

Re: Scripting with Clojure / "slow" boot time

Please excuse the very naive question, but if the main problem seems to be compilation of loaded namespaces, what about aot? Does it help at all? If not, why? As far as I know, the JVM already does lazy loading with Java classes essentially in the way that Mike described. On Wednesday, 10 February

Re: Scripting with Clojure / "slow" boot time

Good initiative, I've filled in a response to the survey. One thing that strikes me is that the main issue with loading time is the time required to transitively load and compile all the referred namespaces (which can be a lot in a big project...). This in turn may trigger class loading of Java
