[slime-devel] What expressions can be inspected with slime-inspect?
What kind of expressions it is possible to inspect with the `slime-inspect' command? Suppose I evaluate this in a SLIME repl: (defclass my-class () ((a) (b)) then invoke `slime-inspect' from a Lisp mode buffer with `C-c I' and type: (make-instance 'cl-user::my-class) I get this error: Error in function PCL::FIND-CLASS-FROM-CELL: No class named: COMMON-LISP-USER::MY-CLASS. [Condition of type SIMPLE-ERROR] Restarts: 0: [ABORT] Abort handling SLIME request. 1: [ABORT] Return to Top-Level. Backtrace: 0: (PCL::FIND-CLASS-FROM-CELL COMMON-LISP-USER::MY-CLASS NIL T) 1: ("DEFMETHOD MAKE-INSTANCE (SYMBOL)" #<#1=unused-arg> #<#1#> COMMON-LISP-USER::MY-CLASS NIL) 2: ("DEFSLIMEFUN INIT-INSPECTOR") --more-- Am I supposed to do that? In which environment does `slime-inspect' evaluate expressions? Paolo -- Why Lisp? http://alu.cliki.net/RtL%20Highlight%20Film

Should work fine, assuming you did the defclass in the CL-USER package. Works for me in CMUCL 19a-pre3.
I get this error:
Error in function PCL::FIND-CLASS-FROM-CELL: No class named: COMMON-LISP-USER::MY-CLASS. [Condition of type SIMPLE-ERROR]
How about if you do the make-instance call from e.g. the REPL instead? It would be strange if it's inspector-specific. The inspector just does READ and EVAL on the input. -Luke

How about with no SLIME at all? This is quite weird. :-)

I think this is a bug in CMUCL 18e. In 19a-pre3 the slime inspector works on this example, and without SLIME I get better results too: $ cmucl -noinit CMU Common Lisp 19a-pre3, running on dodo With core: /usr/local/cmucl-19a-pre3/lib/cmucl/lib/lisp.core Dumped on: Wed, 2004-06-30 19:13:25+02:00 on lorien See <http://www.cons.org/cmucl/> for support information.

I'm going to test 19a-pre3 soon. Thanks, Paolo -- Why Lisp? http://alu.cliki.net/RtL%20Highlight%20Film

I have tested the SLIME inspector with CMUCL 19a-pre3, and I confirm that it indeed works fine with class instances. Paolo -- Why Lisp? http://alu.cliki.net/RtL%20Highlight%20Film
