Refactored swank-clojure, with jpda debugging support.
This is alpha quality.
- Breaks on uncaught exceptions and breakpoints.
- Allows stepping from breakpoints
- Allows evaluation of expressions in the context of a stack frame
- Inspection of locals in any stack frame
[swank-clj "0.1.3"] to your project.clj
Install the slime-clj.el contrib from marmalade.
A compatible slime.el is in slime/slime.el. It is available as a
package file you can
and install with
M-x package-install-file. Note that you may need to remove
this package to use
If you would like to browse into the clojure java sources then add the following
:dev-dependencies, with the appropriate clojure version.
[org.clojure/clojure "1.2.1" :classifier "sources"]
For clojure 1.2.0, you will need the following instead:
To run with jpda:
To run without jpda:
lein swank-clj 4005 localhost :server-ns swank-clj.repl
To set a breakpoint, eval
swank-clj.el from src/main/elisp, put the cursor
on the line where you want a breakpoint, and
Note that breakpoints disappear on recompilation at the moment.
To list breakpoints, use
M-x slime-list-breakpoints or press
b in the
slime-selector. In the listing you can use the following keys
- e enable
- d disable
- g refresh list
- k remove breakpoint
- v view source location
Recompilation of clojure code creates new classes, with the same location as the code they replace. Recompilation therefore looses breakpoints, which are set on the old code. Setting breakpoints by line number finds all the old code too.
A pure JDI backend, that doesn't require swank in the target VM is certainly a possibility.
A slime-eval-symbol-at-point would be useful (requires determining the frame in the current sldb stacktrace using file and line number).
Add watchpoints with logging of locals to an emacs buffer or file.
Run swank server and JDI debugger in the same process to have a single JVM and keep memory usage down
Run swank and debugger in a seperate JVM process. Attach to any -Xdebug enabled JVM process.
Run swank server in process and attach slime as required. This requires the debugger to run in process.
