[slime-devel] Not possible to inspect method slots in Lispworks
The slot #<STANDARD-EFFECTIVE-SLOT-DEFINITION A-METHOD 21C8CD0C> is missing from #<A-CLASS 21C8D174> (of class #<STANDARD-CLASS A-CLASS 21C4734C>), when reading
In the latest version of SLIME from CVS for Lispworks, I receive the following error when I attempt to inspect the values for a slot in an object: the value. << This is for the following: CL-USER> (defclass a-class () ((a-method :accessor a-method))) #<STANDARD-CLASS A-CLASS 21C4734C> CL-USER> (make-instance 'a-class) #<A-CLASS 21C8D174> This used to work in the SLIME CVS version of perhaps a month or so ago. -Luke
It sounds like this is probably related to the recent change to (defun inspect-for-emacs ((o standard-object) inspector) I think perhaps it's advisable to back that recent change out until we either take Pascal's recommendation to use Closer to MOP to implement the slot-boundp-using-class or slowly special-case for different versions until we have a clear working consensus for all the different backends. revert to
collect (if (slot-boundp o slot-name) `(:value ,(slot-value o slot-name)) "#<unbound>")
from: < collect (if (swank-mop:slot-boundp-using-class (class-of o) o slot) < `(:value ,(swank-mop:slot-value-using-class (class-of o) o < (find-effective-slot o slot-name))) < "#<unbound>") Sorry if that caused problems. I'll play around on my end with the original problem (inspecting MOP overloaded slot accessors) and suggest a special case solution for Allegro if it is warranted. Can someone check in this change or revert the prior change? Regards, Ian Luke Crook wrote:

In fact an even better solution, which I just employed and tested locally, is to just create an allegro specific backend method for inspect-for-emacs that handles the case over slot-boundp not calling slot-boundp-using-class. We can address general MOP issues later if enough backends have to go this route per Pascal's earlier e-mail. Ian Ian Eslick wrote:

I did something like this in the CVS version. Helmut.
