McCLIM debugger by Peter Mechlenborg improved

Saturday, April 16, 2005

Peter Mechlenborg has improved the McCLIM-based Lisp debugger he announced some time ago. The tool, which is still in an early stage of development, uses SLIME's portable debugger interface.

Compilation instructions and test forms are at the top of the source file, but there are a couple of things that may not be obvious:

• You have to load SLIME before invoking the debugger.
• The debugger depends on Clouseau, the McCLIM Lisp inspector, which you have to load first, e.g.:

  (asdf:operate 'asdf:load-op :clouseau)
  

  Indeed, the debugger now takes advantage of Clouseau by making it possible to inspect objects in stack frames (left-click on a value).
