Interact with JVM-based plain Clojure from ClojureCLR
Hello all, I've been using core.logic for some code and I haven't read it's ported on ClojureCLR. However, I would like to use that code as game logic and to rely on Unity game engine for the graphical part. That means I have to use Unity and Clojure together: it can be done through Arcadia[1]… which uses ClojureCLR. I could get rid of core.logic but I feel more like trying to let it run on a JVM-based REPL and talk with the graphical part through its CLR-based REPL. Then my question is: how to get two REPL talk to each other? More specifically, the ClojureCLR REPL needs to send commands to the JVM-based REPL and retrieve results. I would greatly appreciate any help :-) Link: [1] https://github.com/arcadia-unity/clojure-clr/tree/unity -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Re: How to use plain Clojure functions in core.logic?
Well, FYI I've figured out you just need to project the variables you
want. Sorry for double-posting.
However I've got no idea about how optimum this is. So please don't
hesitate if you think about any more clever way to use functions in
core.logic :-)

```clojure
(let [depart-state {:a {:a 1 :c 4} ;; b2 missing
:b {:a 2 :b 3 :c 6}
:c 3}
arrival-state {:a {:a 1 :b 2 :c 4}
:b {:a 2 :b 3 :c 6}
:c 3}
modifier (fn [basic x y value]
(assoc-in basic [x y] value))]
(run* [_1 _2 _3]
(membero _1 [:a :b])
(membero _2 [:a :b])
(membero _3 (range 4))
(project [_1 _2 _3]
(clojure.core.logic/== arrival-state
(modifier depart-state _1 _2 _3)
```

How to use plain Clojure functions in core.logic?
Hi everybody, I have defined a plain Clojure function which has a specific logic inside. It outputs a mutated state given an initial state and some other arguments. Basically, we could say it is like: (defn modifier [basic x y value] (assoc-in basic [x y] value)) I want core.logic to deal with it in order to find the correct parameters for this function to output the result I want. Do I have to rewrite it as defne or defnc? methinks it would be a burden (just try to express assoc-in in pure logic) >< so I'd like to find another way. Maybe I could use the (for ) list comprehension but I feel like core.logic has a more clever approach. I have a gist with minimal working code sample here: https://gist.github.com/piotr-yuxuan/fa0cfdc63a26b667c3f3 Will appreciate any help I would be given! :-) Thanks a lot in advance! 胡雨軒 -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Parsing Unicode character with Clojure
I've come on some trouble when parsing an Unicode character with Clojure. I know it's likely to be a problem related to Java and not Clojure itself but I'm looking for a Clojurish solution so that's why I'm posting it here. FYI, I have a GNU / Linux OS on the top on which I use emacs 24 in cunjunction with CIDER 0.10.0snapshot (package: 20150710.1304), Java 1.8.0_51, Clojure 1.6.0 and nREPL 0.2.6. The first character of the Unicode block CJK Unified Ideographs Extension B is (hope you can properly read it, get a Chinese font otherwise). Emacs perfectly deals with it but in gedit, it's like this character would have the glyph you see (something like ㄛ but more angular) plus a negative space. In emacs it's displayed properly but when it comes to be evaluated, the behaviour is weird: ``` Clojure 華文.core (clojure.string/split a a #\ ) ; = [a a] 華文.core (clojure.string/split a a #\u2) [a a] 華文.core (clojure.string/split a a #[\u2-\u2a6df]) ; it spans over Extension B ; = [ ] ``` Moreover: ``` Clojure 華文.core \u2 ; = IllegalArgumentException Invalid unicode character: \u2 clojure.lang.LispReader.readUnicodeChar 華文.core (int \ ) ; = RuntimeException Unsupported character: \ clojure.lang.Util.runtimeException (Util.java:221) 華文.core (format %04x (int \u3403)) ; = 3403 華文.core (format %04x (int \u2)) ; = IllegalArgumentException Invalid unicode character: \u2 clojure.lang.LispReader.readUnicodeChar ``` Finally here is a very annoying side-effect, just like an overflow: from 2 it overlaps values from 0, so the whole legacy ASCII would be contained is this block. ``` Clojure 華文.core (clojure.string/split cabac #[\u2-\u2a6df]) ; = [] 華文.core (clojure.string/split cabac #[a-b]) ; = [] ``` Then I don't really know how I could handle this character. I've picked haphazardly some characters and it seems to be the same mess above \u :/ -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: core logic
Hello Josh, I would be glad you share your code :) Piotr 2013/6/18 David Nolen dnolen.li...@gmail.com This is a variant of the Zebra/Einstein Puzzle.
