This is a strange case (you normally wouldn't use VALUES there) but it comes from some larger real code that sets multiple struct slots from a multiple-value-returning function. -- Ticket URL: <http://trac.common-lisp.net/armedbear/ticket/107> armedbear <http://common-lisp.net/project/armedbear> armedbear

However, abcl says: ABCL-BUG(6): (abcl-bug) #<THREAD "interpreter" {108F8E0}>: Debugger invoked on condition of type SIMPLE-TYPE-ERROR The value #<ABCL-BUG::ITEM {537935}> is not of type ABCL-BUG::ITEM1. Restarts: 0: TOP-LEVEL Return to top level. [1] ABCL-BUG(7): The section he's referring to is this bit which is part of the DEFSTRUCT documentation for the :conc-name keyword argument: Whether or not the :conc-name option is explicitly supplied, the following rule governs name conflicts of generated reader (or accessor) names: For any structure type S1 having a reader function named R for a slot named X1 that is inherited by another structure type S2 that would have a reader function with the same name R for a slot named X2, no definition for R is generated by the definition of S2; instead, the definition of R is inherited from the definition of S1. (In such a case, if X1 and X2 are different slots, the implementation might signal a style warning.) -- Ticket URL: <http://trac.common-lisp.net/armedbear/ticket/106> armedbear <http://common-lisp.net/project/armedbear> armedbear

Probably this was more a problem on the SLIME end of things that has changed. -- Ticket URL: <http://trac.common-lisp.net/armedbear/ticket/17#comment:4> armedbear <http://common-lisp.net/project/armedbear> armedbear

I don't really think there's an issue here. Please reopen if there actually is - detailing the exact error condition or reason why SLIME can't use the --eval or --load route. -- Ticket URL: <http://trac.common-lisp.net/armedbear/ticket/17#comment:3> armedbear <http://common-lisp.net/project/armedbear> armedbear

[armedbear-ticket] [armedbear] #88: Predicate to distinguish between functions implemented directly in Java vs. Lisp

#88: Predicate to distinguish between functions implemented directly in Java vs. Lisp -------------------------+-------------------------------------------------- Reporter: trittweiler | Owner: nobody Type: enhancement | Status: new Priority: minor | Milestone: Component: java | Version: Keywords: | -------------------------+-------------------------------------------------- For Slime, we need a predicate to distinguish between functions implemented in Java, and functions compiled from Lisp. The reason is because we use different mechanism to get at the definition: for Java functions, we'll use TAGS, whereas for Lisp functions we will use source-location information stored by the ABCL compiler. Compiled Lisp functions also end up to be of type Primitive, so just making the Primitive class available to Lisp won't cut it. -- Ticket URL: <http://trac.common-lisp.net/armedbear/ticket/88> armedbear <http://common-lisp.net/project/armedbear> armedbear
