Slime's default inspector won't show slot values for metaclasses that
the default storage locations for objects slots (i.e. where the default
returns nil). The elephant interface to Berkeley-DB is one such
(defmethod inspect-for-emacs ((o standard-object) inspector)
(declare (ignore inspector))
(values "An object."
`("Class: " (:value ,(class-of o)) (:newline)
for slot in (swank-mop:class-slots (class-of o))
for slot-def = (find-effective-slot o slot)
for slot-name = (swank-mop:slot-definition-name slot-def)
collect `(:value ,slot-def ,(string slot-name))
collect " = "
collect (if (swank-mop:slot-boundp-using-class
(class-of o) o slot)
(class-of o) o slot-def))
If you add the two calls to slot-boundp-using-class and
slot-value-using-class as shown
above you get the expected proper behavior for lisps that don't call the
mop functions from the slot-value and slot-boundp functions. (I ran
into this on Allegro 7.0
under Mac OS X).
The other change is to add these two functions to the swank-mop package
It's a minor enough change I figured someone who checks in regularly can
update this and
provide some judgement on whether there are likely to be any problems.
