Hello,
I'm a clojure newbie, with little java experience.
I've been skimming the net the last few days trying to solve my
problem.
Could anyone help?
Here it is:
I followed the instructions given by Rich on how to use JSwat with
Clojure.
The only difference is I'm using JSwat 4.5, the latest official
release, running on Mac OS X 10.6.
(Note that I had the same problem on 10.5).
I also read the extra info gathered on this group in the "Debugging
with JSwat" thread.
Problem:
- Can't get the line numbers to show up on .clj files in JSwat (even
after selecting the menu option...)
- Can't set any line breakpoint on sessions attached to Clojure REPL.
What I can do:
- run Clojure in CLI or using VimClojure, no problem.
- can attach to remote session on JSwat and Pause/Continue the main
thread (I can see the effect on the REPL
in a Terminal session).
- can break on exceptions
Do I have to compile in order to be able to debug my clj files?
I naively thought you could work in User space and in one clj file and
reload and run in JSwat, as Rich is
hinting in his debugging page.
Like I said, I'm not deeply familiar with Java (yet), so I thought
this could be a classpath problem.
I set my CLASSPATH environment variable to contain:
- clojure installation dir with.jar
- clojure/src
- clojure-contrib.jar (not using it in my code yet)
-clojure-contrib/src
- vimclojure stuff
- . (current dir)
- ./classes (even though I have not compiled yet).
If I try to execute a newline of code in the loaded clj file in JSwat,
here's the error I get:
VM suspended for session Session 1
Error in breakpoint: Line brain.clj:69
There is no line number information for user$eval__69

What am I missing here? There's got to be something obvious that I
over-looked!
I would greatly appreciate it if you could help!
Thanks!
