It is possible to execute forms in a debugging context but AFAIK there is no easy setup that allows you to step through the execution.
The easiest way to evaluate forms in context is to setup emacs as described here http://clojure-doc.org/articles/tutorials/emacs.html. This will allow you to set breakpoints by inserting (swank.core/break) as described here http://hugoduncan.org/post/2010/swank_clojure_gets_a_break_with_the_local_environment.xhtml. This slime/swank setup is robust and well documented. nrepl-ritz offers a new way to set up emacs with a debugger. It has just been introduced by Hugo Duncan in the Clojure/conj and it works well for me. It is described here https://github.com/pallet/ritz/tree/develop/nrepl. It brings some functionality that is not available through slime/swank but it is not as complete and battle tested. To me the biggest benefit of this new setup is the ability to examine the stacktrace on exceptions. It allows you to inspect values and evaluate expressions at any point in the stacktrace. I find this to be helpful not only for my own errors but also for compiler errors because you can often find the expression that the compiler is complaining about somewhere in the stacktrace. Stepping through the execution is harder to setup but it might be possible. The CDT debugger can be set up as described here http://georgejahad.com/clojure/swank-cdt.html. It worked great for me at some point but I'm no longer using it because doesn't work with openjdk AFAIK, On Monday, November 26, 2012 11:15:44 PM UTC+1, Sol Tourne wrote: > > > > In your list, the only thing you won't be able to do with Eclipse is > executing clojure forms in the context of the breakpoint. > > Thanks, that's very useful info. > > Is that doable in emacs?
