It'd be better, when coming up with great ideas, if you didn't reply to 15-month-old threads as if they were recent! It makes for very confusing reading in most mail clients. Better to start a new thread, if you feel like the discussion is still relevant. - Korny On 19 Jul 2013 22:28, "Daniel Dinn

concat primitive arrays

Is there an easy, fast way to concat primitive arrays? I was hoping java arrays had some common interface for this, but I haven't found much of use. I mostly see code like this: byte[] c = new byte[a.length + b.length]; System.arraycopy(a, 0, c, 0, a.length); System.arraycopy(b, 0, c, a.length,

Re: separate namespace for extra-special forms?

fn and let are macros in the clojure.core namespace; & is technically not a valid character in a symbol, but the Clojure reader is quite lenient on that front. As far as I know, it is not treated as anything special at the level of the language, it is just interpreted by the destructuring macros.

I've been looking at hiphip, though it's not clear to me how it's related to h2 user functions. ;) It wasn't immediately clear to me if hiphip handles multidimensional matix operations. On Saturday, July 20, 2013 9:32:50 AM UTC-7, Alex Fowler wrote: > > BTW, take a look > http://blog.getprisma

Re: java interop: passing int[]

So, out of what you're saying - you want to implement an interface, without adding new methods - I strongly suggest using proxy and delegate all the type-resolution hassle to JVM (just rely on it). If you are really sure you need specifying types explicitly, then use type hints and dedicated cl

Re: primitive array casts

Type hints are given so the compiler can optimize the generated code by assuming first that the value passed will be of the type hint. It does not preclude you from passing something that is not what the hint says it should be. In this case the usual behavior is to use reflection on the value cl

Can you explain this more? In the second example, it's unhappy because a vector is not a primitive array? And I don't understand the idea of a "soft hint". It looks like "this may be ints", but that's true without the hint. So what is the hint doing? On Saturday, July 20, 2013 2:31:50 AM UTC-7,

I'm trying to write a user function for h2. I think that means I need gen-class, but I'm extremely fuzzy on how java class loading works. Perhaps my question is moot, because I just ran across this obscure note in a gen-class example: ;; declare only new methods, not superclass methods If I'm

Example: user=> (meta (find-ns 'clojure.set)) nil user=> (meta (find-ns 'clojure.string)) nil user=> (meta (find-ns 'clojure.core)) {:doc "Fundamental library of the Clojure language"} clojure.core is the only namespace that has metadata. Apparently because it has metadata set differently https

Also, ^foo-style hints are "soft hints" in the following sense: (let [^ints xs [1 2 3]] xs) ; no complaint from compiler or RTE In contrast, ints & Co. demand that the casts be correct: (let [xs (ints [1 2 3])] xs) ; ClassCastException On 20 July 2013 11:29, Michał Marczyk wrote: > More compl

I think it's more about clojure.core/{ints,longs,...}. These are basically tools for removing reflection: (let [xs (ints (get-some-ints))] (aget xs 0)) ; no reflection here thanks to the cast Cheers, Michał On 20 July 2013 10:47, Mikera wrote: > Do you mean something like (int-array [1 2 3

Re: primitive array casts

Do you mean something like (int-array [1 2 3 4])? This is a cast-like operation that produces a primitive array of ints, exactly like int[] in Java. You can then use it with array operations like "aget". If you want to type-hint int-array parameters then you need to use something like "^ints"
