* module/oop/goops.scm (fold-class-slots): Change format to use proper
slot specifications.
(fold-slot-slots): Flesh out with all needed slots.
(<class>): Update cons-layout to deal with new fold-class-slots form.
Don't create slots; we do that later.
(is-a?, get-keyword, *unbound, unbound?, %allocate-instance): Move
definitions up.
(<slot>, slot?): New definitions.
(slot-definition-name, slot-definition-allocation)
(slot-definition-init-keyword, slot-definition-init-form)
(slot-definition-init-value, slot-definition-init-thunk)
(slot-definition-options, slot-definition-getter)
(slot-definition-setter, slot-definition-accessor)
(slot-definition-slot-ref, slot-definition-slot-set!)
(slot-definition-index, slot-definition-size): New definitions as
accessors on <slot> objects.
(class-slot-definition): Adapt to class-slots change.
(direct-slot-definition-class, make-slot): New definitions.
(make): Define a boot version that can allocate <slot> instances.
(compute-direct-slot-definition)
(compute-direct-slot-definition-initargs)
(effective-slot-definition-class, compute-effective-slot-definition):
New definitions.
(build-slots-list): Adapt to slots being <slot> objects.
(compute-get-n-set): New boot definition.
(allocate-slots): New definition. Replaces
compute-getters-n-setters.
(%compute-layout, %prep-layout): Adapt to changes.
(make-standard-class): Make <slot> objects for direct-slots, and
handle the allocate-slots protocol.
(<foreign-slot>): Inherit from <slot>.
(get-slot-value-using-name, set-slot-value-using-name!)
(test-slot-existence): Adapt to using slot definition objects.
(make-class): Allow slot specs or <slot> objects as the `slots'
argument.
(write): New method on <slot>.
(class-slot-ref, class-slot-set!): Reimplement.
(compute-slot-accessors, compute-getter-method)
(compute-setter-method): Adapt to changes.
(compute-getters-n-setters): Remove. Yay!
(compute-get-n-set): Adapt to use effective slot definitions instead
of the getters-n-setters for #:class / #:each-subclass allocation.
(%initialize-object): Adapt.
(initialize): New method for <slot>. Adapt method for <class>.
* module/oop/goops/active-slot.scm (compute-get-n-set):
* module/oop/goops/composite-slot.scm (compute-propagated-get-n-set):
Use slot-definition-options to access options of slot.
* test-suite/tests/goops.test ("bad init-thunk"): Fix to be a "pass-if"
instead of an "expect-fail".
* libguile/goops.c (SCM_GOOPS_UNBOUND, SCM_GOOPS_UNBOUNDP): Remove
internal macros.
(scm_make_unbound, scm_unbound_p): Remove internal functions.
(scm_sys_clear_fields_x): Add "unbound" parameter, for the init
value.
* module/oop/goops.scm (*unbound*): Define in Scheme as a simple
heap-allocated value.
(unbound?): New definition.
(%allocate-instance): Pass *unbound* to %clear-fields!.
(make-class, slot-definition-init-value)
(slot-definition-init-form, make-closure-variable): Use *unbound*
instead of (make-unbound), which is now gone.
* module/oop/goops/active-slot.scm (compute-get-n-set): Use *unbound*
instead of make-unbound. This module uses the GOOPS internals module;
perhaps we should export make-unbound or something...
* module/oop/goops/save.scm (make-unbound): Export our own make-unbound
definition, for use by residualized save code.
* module/language/ecmascript/base.scm (<undefined>, *undefined*): Use a
unique object kind and instance for the undefined value.
* libguile/vm.c (scm_i_vm_mark_stack): Fill the stack with
SCM_UNSPECIFIED instead of SCM_UNBOUND.
* libguile/goops.h:
* libguile/goops.c (scm_sys_fast_slot_ref, scm_sys_fast_slot_set_x):
Remove these unused, unsafe functions. They were publically available
only to C.
* module/oop/goops/active-slot.scm (compute-get-n-set): Update to use
struct-ref / struct-set! instead of %fast-slot-ref / %fast-slot-set!
from (oop goops internal).
* module/oop/goops.scm, module/oop/goops/active-slot.scm,
module/oop/goops/composite-slot.scm, module/oop/goops/describe.scm:
Add a copyright line for Érick Gallesio. Mention the STk version
GOOPS was derived from. Remove mentions of the ‘COPYRIGHTS’ file.
Thanks to Karl Berry <karl@freefriends.org> for pointing it out, and
to Michael Djurfeldt <mikael@djurfeldt.com>.
Moved ice-9/ and oop/ under module/, with the idea being that we have
only scheme under module/. Adjusted configure.in and Makefile.am
appropriately. Put oop/ at the end of the compilation order.
