Source-level stepping in Allegro CL
P. Srinivas
Hi all,
Does anybody has a piece of CL/Elisp code that can do source-level
stepping of Allegro CL code? I am looking for something similar
to what GDB does with C code using Emacs. I remember seeing
something like this for CMUCL. But I did not remember the
exact place.
This functionality does not seem to be part of Allegro CL <-> Emacs
interface package FI that comes with ACL. Somebody mentioned that such
a beast is a part of Allegro Composer, which is an expensive
add-on thing from Franz.
Thanks a lot.

Ok, I was not clear enough. What I was asking for is an emacs interface
to the traditional 'step' form of ACL. Step form is good but not
very user-friendly when I want to step through complex code with
lots of loops and macros. What I want is some interface that hides all
this stuff and shows me the the 'same source file' in another window
with current form being stepped highlighted or 'marked somwhow.
Just like GUD-mode does with C soucse while debugging with GDB.

As a Lisp advocate I have to admit that this is one feature of C that I
wished I had in Lisp. However it should not be too difficult to write the
Elisp code. Basically it would grab the expression that point is in and its
top level defining form. It would redefine the top level form with a
wrapper on the point expression and send the new top level form to the Lisp
process. The wrappers and keeping track of the breakpoints could get a
little tricky so as not to introduce any compound effects. I could work on
such a package, but I would like to know (as would P. Srinivas) if anyone
has already done such.
You could take a look at ILISP for example at
http://www.cs.wisc.edu/csl/texihtml/xemacs-19.13/ilisp_toc.html
but I don't recall this has what I am suggesting above, at least it didn't
when I looked at it years ago.
Also the lisp FAQ says that Edebug see
http://www.inf.tu-dresden.de/info/edebug
has some debugging utilities for Common Lisp, but if I recall the ones to do
the above kind of breakpointing are for Elisp.

Does this edebug works on any inferior CL process? or is it just
for Emacs Lisp alone.

Sorry. I forgot to mention that edebug is meant for debugging emacs
lisp only. Some hacking may make it work for others. Never looked at
it.

Just for clarity. This is not the official ILISP site. The
AI.Repository at CMU usually carries a recent version. You can get
the "latest" version of ILISP (5.8a4) at
