Swank freezes on swank.core/break called from within 'for'.
Sample can be found here: http://gist.github.com/403585#file_swank_break_freeze.clj

If I (def primes [1 3 5 7 11 13]), and try your example, then the break functionality works fine for me.

Which versions of clojure and swank-clojure?

neotyk commented May 18, 2010

if I def primes like that, than it works for me as well.
But my example was using clojure.contrib.lazy-seqs/primes and I suppose that similar definition would yield same freeze result.

[org.clojure/clojure "1.2.0-master-SNAPSHOT"]
:dev [swank-clojure "1.2.1"]

The dangers of use - I missed that one. However, it doesn't change anything here, I still get a functioning break with clojure.contrib.lazy-seqs/primes, and am using the same versions.

Hit [enter] on first frame to see locals.

OK, reproduced. The problem here is that it is trying to display the whole of the lazy sequence.

commands.basic/locals-for-emacs is calling str on the lazy sequence.
