Re: Clojure + Intellij IDEA: stepping through Clojure implementation code
Hello, and thanks everyone for the information. I have this Visual Studio + ClojureCLR + Emacs (last one to run a REPL in a *shell* buffer) setup that I use to experiment with ClojureCLR. What I do is have the REPL in Emacs, attach to it from Visual Studio, set breakpoints, use Immediate Mode etc. I also need to be able to modify the ClojureCLR code, recompile, restart the REPL, test various things. I was looking for something similar for Clojure on the JVM, and I think that the setup Rich described is as close to the ClojureCLR setup as it gets. However, since La Clojure was only a few clicks away after installing IDEA, I also played a little with La Clojure. Some questions: 1) I noticed that stepping into from a Clojure breakpoint takes me to the Java code. I assume that I pop back into Clojure code when reaching an .invoke. Is there a switch to keep stepping into Clojure only (kind of fast forwarding on the Java under-the-hood part)? 2) I didn't manage to see values of locals while stopped on a breakpoint in a Clojure function. How is that done? My test was very simple, a hello function (defn hello [greetee] (str hello greetee)) and a call to that function. I wanted to see the value of the 'greetee' parameter of the hello function. 3) Is there something similar to Visual Studio's immediate window in IDEA or LaClojure? If there is not, maybe there's a way to integrate the debug repl that was discussed on the list a couple of weeks ago (or something like it) in La Clojure?

Re: Clojure + Intellij IDEA: stepping through Clojure implementation code
Don't know about the current IDEA La Clojure clojure plugin status. But concerning Eclipse (and its counterclockwise plugin), what you describe here works well AFAIK. It's also possible to place breakpoints on your own .clj files. You can quickly start from here : http://code.google.com/p/counterclockwise/wiki/Documentation#Install_Counterclockwise_plugin HTH, -- Laurent 2010/1/1 Miron Brezuleanu mbr...@gmail.com: Hello, In order to get a better understanding of how some things happen in Clojure, I'd like to step through Clojure code (and I mean the Java code used to implement Clojure).

Re: Clojure + Intellij IDEA: stepping through Clojure implementation code
Now when I try to get a REPL (by using clojure.main as the startup class), I get an error about clojure/core.clj not being on the classpath. While a very rough solution would be to just move clj/clojure somewhere on the path, I'd like to know how to change the classpath for a module. Are you using the La Clojure plugin? You can start a REPL console from the tools menu (Tools -Clojure REPL - Add New, bound to CTRL-ALT-A by default). If not, the best thing would be to install it: 1. go to File - Settings 2. select the Plugins section from the list on the left 3. type clojure into the plugin search box 4. select the La Clojure plugin (it'll be under the available tab 5. click on the install button at the top left of the plugins page I did try playing with the module settings and add a 'library' which has a path to clj/clojure, but I must be doing something wrong, as it doesn't seem to affect the -cp option of the java invocation (I'm checking this using the output window). The REPL that LaClojure gives you will have the same class path as your clojure project - so you should have both Clojure Clojure Contrib available, as well as any libraries that your project has defined. Hope this helps! Cheers, Ian. -- You received this message because you are subscribed to the Google Groups Clojure group.
