Re: How to use params in java?
Hi,
here an example step-by-step:
import clojure.lang.RT;
import clojure.lang.IPersistentVector;
import clojure.lang.PersistentVector;
import clojure.lang.Keyword;
public class SomeClass {
public static void main(String[] args) {
Var prn = RT.var(clojure.core, prn);
Keyword a = Keyword.intern(a);
Keyword b = Keyword.intern(b);
IPersistentVector v = PersistentVector.create(a, b);
prn.invoke(v);
}
}
I haven't tested it, but this should print [:a :b].
Hope this helps to get you going.
Sincerely
Meikel

Hello, Armando! do you can give me short example?

Re: How to use params in java?
I don't have any examples; using a Clojure lib like that is a real pain. As you can see, interop to Java doesn't just happens but it must be designed into a library. You may want to consider adding an interop layer on top that vijual thingy or use plain scripting for everything and not use invoke.

Re: How to use params in java?
I don't need concrete example with vijual, I don't understand how to use this parameters whatever vijual -( Thanks for the help, Armando, I'm trying do this.

Re: How to use params in java?
You need to use a few more classes from jvm/clojure/lang. For example,
with PersistentVector#create(Object...) and one of the
Keyword#intern() calls you should be able to construct myParams.

Hi! I use clojure from java. And I don't know how to send params to
clojure
I use Vijual Graph Layout Library for Clojure (https://github.com/
drcode/vijual). Some methods has params, for example:
(draw-graph-image [[:a :b] [:b :c] [:c :d] [:a :d] [:e :f] [:a :f]
[:g :e] [:d :e]])
or
(draw-graph-image [[:to-cellar :living-room] [:living-
room :kitchen] ...blah blah
_
My java code:
public static void main(String args[]) throws Exception {
BufferedReader br = new BufferedReader(new FileReader(new
File(res/test.clj)));
StringBuilder sb = new StringBuilder();
String line;
while((line = br.readLine())!= null){
sb.append(line);
sb.append(\n);
}
Compiler.load(new StringReader(sb.toString()));
RT.var(vijual, func).invoke(I am here!);
Var draw = RT.var(vijual, draw-tree-image);
Var save = RT.var(vijual, save-image);
// params should be here!
draw.invoke(myParams); //this is trouble...
save.invoke(new BufferedImage(500,500,1), C:/AA);
}
Can you help me?
