As some of you know, I suffer from a seemingly interminable obsession
with improving the Clojure debugging story. It just seems so clear to
me that Clojure deserves a world class debugger, one befitting it's
power, beauty and elegance. Maybe one day, we'll get there. Till
then, here are my latest improvements to the CDT:
1. Stepping
2. Line number breakpoints
3. An Emacs based front end which allows you to: step, set
breakpoints, catch exceptions, eval remote clojure expressions, and go
up and down the stack, in a much more natural way than with just the
command line.
When you want to eval the s-expr under the cursor, hit ^x^a^p!
CDT will then serialize the s-expr, send it to the remote vm, evaluate
it there in the context of the current stack frame, and display the
result on the mode line.
Ridiculously long instructions on how to use it are here:
http://georgejahad.com/clojure/emacs-cdt.html
I should emphasize that there is nothing Emacs specific about the
CDT. In fact, I've been so spoiled by Clojure, I don't even enjoy
writing Elisp any more. This front end was written in Emacs because
that's the IDE I'm most familiar with. The CDT command line is IDE
agnostic; it should be easy, (dare I say fun?), to port it to other
IDE's. If there's interest, I'll detail how in a future post.
Many thanks to Fogus for the kind words, and to the Runa gang for
their continuing encouragement!

Wow, looks very useful. Quickly perusing the 'ridiculously long instructions' it seems that it isn't compatible with slime.
Is this the case? Does slime fit into your workflow, and if so, how?

I regularly use both simultaneously.
While Slime and the CDT don't currently leverage each other, they
don't interfere with each other either as far as I know, unless you
happen to suspend the swank server thread. Not sure what all the
implications of that are. I'm still learning.
Why do you ask? Is there some particular functionality you are
interested in?
When I want to use both simultaneously, I eval this in my .emacs:
(setq swank-clojure-extra-vm-args '("-
agentlib:jdwp=transport=dt_socket,address=8021,server=y,suspend=n"))

Well, I'm just learning too. Currently I rely on lein swank to start up my JVM so that slime can connect to it. CDT seems to want you to manually start up the JVM with a particular set of flags. So, do you therefore use two JVM instances?
I guess I could do with sitting and pairing for 10 mins to see how things work ;-)
Is there any chance you could record a short screencast of this stuff in action?

Leiningen honours the JAVA_OPTS environment variable. If you do this -
$ export JAVA_OPTS="-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=8021"
$ lein swank
Then lein will start the JVM with the required flags. After that,
there is no reason why CDT shouldn't work.

Great stuff! Would it be possible to write a version of the tutorial that shows how to accomplish the same things purely from the command line? While I love Emacs as much as the next guy, I think a tutorial that shows how to debug using only the CDT REPL would be useful to many people.

Tried it out just now. Works as advertised. Will dive deeper in a
while. Clojure deserves a great debugging infrastructure. I believe
CDT is a big step in the right direction.
Thanks a lot, George!

Is there any way to pass java_opts arguments to lein on the command
line?
Currently I use the :jvm-opts keyword in project.clj, however it would
be nice to be able to specify different argument when using different
tools as mentioned in the thread above, or to be able to set different
values (e.g. maximum heap sizes) depending on resources of the current
computer.
Is there an accepted way to handle these situations? If not would this
make a good item for future lein development?

You can use unquote to embed arbitrary evaluations in your project.clj:
(defproject foo "1.0.0"
:dependencies [[clojure "1.2.0"]]
:jvm-opts [~(str "-Xmx" (if (= "64" (System/getProperty
"sun.arch.data.model")) "2g" "1g"))])
Untested, but you get the idea.

hmmm, you must be as big a debugger geek as I am, but I'm not sure
anyone else would be interested.
In any case the commands are almost trivial, which is why I don't
think it will be too hard to port this to other IDE's:
These are the CDT commands that were generated by the Emacs front end
in the first example:
(set-bp clojure.set/difference)
(reval s1)
(reval s2)
(reval count)
(reval (count s2))
(step-over)
(reval (reduce disj s1 s2))
(up)
(down)
(cont)
(line-bp "/Users/georgejahad/incoming/clo11/clojure/src/clj/clojure/
set.clj" 56)

I forgot to make clear in my post that port 8021 is just an example,
you should use another if that one is in use, and you get this error:
[null] ERROR: transport error 202: bind failed: Address already in use
[null] ERROR: JDWP Transport dt_socket failed to initialize,
TRANSPORT_INIT(510)
Adie mentioned that you don't need to specify a port at all:
"-agentlib:jdwp=transport=dt_socket,server=y,suspend=n"
java will pick one for you and display it on stdout, and you can use
that as the parameter to cdt.
Also, Sam, my previous post seems to have gotten eaten, but I'll work
on that screencast.

I believe this is not caused by any problems with the debugging environment.
Instead you appear to not have the clojure jar on your classpath.
I would recommend you explicitly launch java with
java -cp "H:\path\to\clojure.jar"
plus any additional arguments of course.
if this is still not working for you, please post the exact command
you are using to invoke java,
as well as a listing of all jars on your classpath, and I'll try to
help some more.
Good luck,

Thanks for your "ridiculously long instructions" on using cdt; I
appreciate your thoroughness.
I'm working on the %$#%$#@^@! Windows platform (Windows XP, to be
precise), and I'm unable to set cdt-source-path in my .emacs file.
I can get my Clojure REPL to start just fine:
----
C:\tech>java -
agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=8021
-client -cp c:\tech\clojure-contrib-1.2.0\target\clojure-
contrib-1.2.0.jar;c:\te
ch\clojure-1.2.0\clojure.jar clojure.main --repl
Listening for transport dt_socket at address: 8021
Clojure 1.2.0
user=>
----
Here's what I have in my .emacs file:
----
(progn
(setq cdt-dir "/tech/cdt")
(setq cdt-source-path "/tech/clojure-1.2.0/src/jvm;/tech/
clojure-1.2.0/src/clj;/tech/clojure-contrib-1.2.0/src/main/clojure")
(load-file (format "%s/ide/emacs/cdt.el" cdt-dir)))
----
When I select and execute it from within Emacs, I get a message in the
minibuffer that says "Loading c:/tech/cdt/ide/emacs/cdt.el
(source)...done". But when I type M-x cdt and set the port to 8021,
the following error message goes into the buffer named *gud-
clojure.main*:
----

I don't know how to handle Windows pathnames, especially the drive
letter, in the context of (setq cdt-source-path.... I tried taking off
the "/c/" or "c:\" for cdt-dir, and that seems to work. But trying the
same thing for cdt-source-path doesn't seem to work. I'm wondering,
should path names be delimited by colons (as Unix expects), or by
semicolons (as Windows expects). I've tried various combinations, I've
tried to find the Java conventions for Windows classpaths... nothing
seems to work.
Any suggestions from anybody will be appreciated. Thanks.

I haven't gotten it working on Windows yet, (as I mention here:
http://georgejahad.com/clojure/emacs-cdt.html)
I don't think it will be hard, but I've never run Clojure on Windows,
so I'm not sure of the issues involved. I need someone like you to
help me figure them out. I'm guessing the most important issue is the
one you are running into, the path/file separator differences.
I've just pushed my best guess at a fix for windows to the windows
branch here:
http://github.com/GeorgeJahad/cdt
Can you try doing a:
git fetch
git checkout windows
from within your cdt repo, and see if that works any better for you?
Thanks!

George, I don't know what time zone you live in, but you are one crazy
person! You're doing fantastic work for the Clojure community, and I
thank you very much for that!
The Emacs I was using was Clojure Box, so I disconnected slime (just
in case) and tried what you suggested. The results were better, but
still not success, so I downloaded and installed a fresh version of
W32 Emacs (i.e., Emacs only, no Clojure add-ons), then I started over.
Here's the result of refreshing the cdt directory (from the git-bash
shell):
-----
$ git pull origin windows
remote: Counting objects: 17, done.
remote: Compressing objects: 100% (4/4), done.
remote: Total 9 (delta 3), reused 0 (delta 0)
Unpacking objects: 100% (9/9), done.

I don't know what went wrong with the last command, but some files
were changed in the directory.
From a Windows cmd shell window, I got the target REPL working with
the following command:
----
contrib-1.2.0.jar;\tech\clojure-1.2.0\clojure.jar clojure.main --repl
----
I did some research on how cmd works, and I found that the cd command
has a special syntax for changing the target disk drive--in other
words, it's as if, normally, the cd command is "blind" to the
existence of multiple hard disks. A Microsoft web page described the
following behavior:
----
C:\tech\cdt>cd \
C:\>
----
You could say that "\" acts like root on UNIX systems (!). This
explains why the backslash classpath separated by semicolons in the
above java command (probably) works. Onward.
OK, so now I have a fresh, untainted copy of Emacs. I put the
following in the .emacs file (which is otherwise empty):
----
(progn
(setq cdt-dir "/tech/cdt")
(setq cdt-source-path "/tech/clojure-1.2.0/src/jvm:/tech/
clojure-1.2.0/src/clj:/tech/clojure-contrib-1.2.0/src/main/clojure:")
(load-file (format "%s/ide/emacs/cdt.el" cdt-dir)))
----
I open Emacs, execute M-x cdt, and get the following result:
----
Current directory is c:/Documents and Settings/add-minimum/Application
Data/

user=> java.lang.ClassNotFoundException: com.sun.jdi.Bootstrap

Hooray! A REPL! I start reenacting your test-drive scenario and get
the following result:

So that's the state of things. I'll be glad to work with you to get
this working on Windows. What so ironic is that I worked for Apple for
10 years, and the *only* reason I'm doing this on a PC is that the
Nuance/Dragon speech-recognition system for the PC is vastly superior
to its (just purchased by Nuance) MacOS X equivalent (sigh).

like most people, it really encourages me when I hear that people like
my work. Basically, I'm just trying to emulate the behavior of all
the studs that came before me, from RH on down. I'm proud to be able
to contribute anything at all to this amazing community! It's so
exciting how everything is coming together for Clojure right now.
Can't wait to see what happens next.
OK, enough rhapsodizing.
With respect to the Windows port, I just got an email from Leo S.
saying he has it working on Windows. As soon as we figure out the
best way to distribute his fixes, I'll let you know.

Unfortunately, no. I just have some hand RSI problems, and I use
Dragon NaturallySpeaking for writing e-mails and documenting Clojure
code. You can see an example of the notes I've taken while going

path path path path path)))
I guess there is a nicer solution :-/

This works for me under Windows 7. I set all forward slashes paths in
my .emacs file like this:
(progn
(setq cdt-dir "c:/msysgit/cdt")
(setq cdt-source-path "c:/clj/clojure-1.2.0/src/jvm;c:/clj/

clojure/contrib;")
(load-file (format "%s/ide/emacs/cdt.el" cdt-dir)))
And these are the diffs from George's current windows version
(hopefully George will be able to make them available in a more
convenient way) - and note the "file:///" with 3 slashes under
Windows:

I suppose it could be a way to unify both versions using (System/
getProperty "path.separator") and (System/getProperty
"file.separator")
I add the leo changes (to master vesion -lesses changes-) and it works
for me
thanks!!

I'm on Ubuntu and getting this same error. I can load up the repl no problem (tried with java command, and also with lein swank/slime), but after setting my port on M-x cdt, I get the following in gud-clojure.main:
Current directory is ~/
Clojure 1.2.0
user=> java.lang.ClassNotFoundException: com.sun.jdi.Bootstrap (cdt.clj:30)
user=> java.lang.Exception: Unable to resolve symbol: CDT-DISPLAY-MSG in this context (NO_SOURCE_FILE:2)
user=> java.lang.Exception: Unable to resolve symbol: set-source-path in this context (NO_SOURCE_FILE:3)
user=> java.lang.Exception: Unable to resolve symbol: cdt-attach in this context (NO_SOURCE_FILE:4)
I followed these directions: http://georgejahad.com/clojure/emacs-cdt.html. Any ideas?

couple of thoughts:
cdt uses the jdk's tools.jar for access to the java debug interface,
(jdi).
it's expecting it here:
(format "file:///%s/../lib/tools.jar" (System/getProperty
"java.home"))
do you have such a file there?
"java.home"))
if not, do you have a tools.jar file anywhere else?
which jdk are you using, sun's or openjdk?
i'm pretty sure tools.jar comes with both, but i can't recall if i
ever looked for it in openjdk.
hth,

George,
Thanks for the response. I'm using openjdk and it lives: file:////usr/lib/jvm/java-6-openjdk/jre/../lib/tools.jar (and the format function worked to find that as well). Anything I need to change wrt that?
Thanks,
Jeff

try adding that jar to your classpath, and see if that fixes it.
if not, run "jar -tf" on the tools.jar file to dump the table of
contents on it and email it to me and i'll see if i can figure out
what is going on.

my apologies George - upon closer inspection, I don't have a tools.jar file - must have been in a daze before...I updated openjdk-6-jdk and it's update included the tools.jar file (not sure why it wasn't there to begin with though)...now I'm happily humming along with CDT....thanks for all your hard work on this!
