ikvm and .NET

[Mark J P]

Steps for running clojure as a .NET app and instantiating .NET types.

- I converted the clojure.jar to clojure.dll: ikvmc -target:library c:
\path\to\clojure.jar (this creates clojure.dll)
- Convert mscorlib.dll to mscorlib.jar: ikvmstub mscorlib.dll
- Create a .net c# console app, and add reference to clojure.dll
- Change Main to this:
static void Main(string[] args)
{
clojure.lang.Repl.main(new string[] {});
}
- Run console app (Repl) and add mscorlib.jar to classpath via
clojure: (add-classpath file://c:.....)

Now you can instantiate .net types
(def i (new cli.System.Int32))
(def s (new cli.System.String nil))

hmmm, the .NET String thing isn't quite working for some reason.
Seems like it converts to the java string. I can work with
StringBuilder though:

(def sb (new cli.System.Text.StringBuilder))
(. sb (Append "asdf"))

Forgot to include this step:

Add a reference to IKVM.OpenJDK.ClassLibrary.dll in the .NET Project

By the way, this is great for embedding Clojure in your .NET app. If all you want is a REPL, you can skip the C# app step and use the -target:exe switch to get a clojure.exe.

The topic has also been explored in a past thread: http://groups.google.com/group/clojure/browse_thread/thread/e48b64f3dc1f09fb/09919e06ebe95d85?lnk=gst.
