problems debugging using Cusp

[Gregg Williams]

Hi-- I'm new to Common LISP after a hiatus of over 10 years (!), and I
was very glad to find an alternative to Emacs and Common LISP.
However, now I need to debug some code, and I'm not sure that Cusp is
for me. Despite an entire day looking for documentation/tutorials/
etc., I can't seem to find how to accomplish setting breakpoints or
stepping through source code. I can insert break statements in my
code, but I can't find any way to look at the state of the system
(e.g., inspect variable values)--all I can do is continue the
execution until the code gets another break statement.

Also, I could use a pointer to something that tells me how to read
error messages when Common LISP prints one out.

This frustrated newbie would appreciate any help that might be
offered. Thanks.

This is indeed a rather serious omission from the debugger. If you're
brave enough to run Cusp from svn, I've just added in support for
stepping. It looks like the debugger could use a little more love in
terms of getting synced back up with swank changes, so I expect I'll
be making a few more commits there in the near future.

I don't know about a good guide to error messages. What kind of
messages are you getting that you're finding confusing?
