I can't directly help you with C#, but I think the problem here is not
related to the host platform, and the code snippet below (which is in Java)
should be easy enough to translate.
It's a bit tricky because def is not actually a function and can thus not
be accessed from Java (or C#) using the official API.
Fortunately, the function clojure.core/intern does what you want: bind a
new value to a symbol.
(If you want to access the value from Java/C#, you also have to manually
unpack it from the Var as shown below.)
package temp;
import clojure.java.api.Clojure;
import clojure.lang.IFn;
public class TestInterop {
public static void main(String[] args) {
IFn intern = Clojure.var("clojure.core", "intern");
IFn symbol = Clojure.var("clojure.core", "symbol");
IFn println = Clojure.var("clojure.core", "println");
IFn var_get = Clojure.var("clojure.core", "var-get");
// Bind the hello symbol in the user namespace
intern.invoke(symbol.invoke("user"),
symbol.invoke("hello"),
4);
IFn my_var = Clojure.var("user", "hello");
// Print the actual var associated to the symbol hello in ns user
println.invoke(my_var);
// Print the value associated to the var
println.invoke(var_get.invoke(my_var));
}
}
Please do note, however, that I believe you might be approaching the
problem from a weird angle, as it would probably be much easier to define
an atom in Clojure and expose a function that sets its value.
