of README.
- fpd.l, fpd.y, README: added debugging directives %del, %move, %print, %dump,
and %exit
- obj.h, fpd.y (find_obj, find_label, new_obj): objects can now be labeled
- obj.c (obj_anchors), inst.c (inst_anchors): gathering the list of anchors is
now a per-object function, not an instance "method". inst_anchors implements
the vector vs. object switch.
- inst.h, inst.c: removed all *_op_anchors functions
- expr.c (str_unit): in the past, we returned a malloc'ed string, but these
times are long gone. Thus, don't stralloc("").

|
* that risk doesn't exist. Furthermore, the way activate_item is used, its
|
|
* preconditions aren't met. It works anyway but it could be simpler as a
|
|
* consequence.
|
|
*
|
|
* activate_item tries to activate the path through the frame references,
|
|
* leading to a specific instance. It returns whether this is failed or whether
|
|
* it may have been successful.
|
|
*
|
|
* The initial condition is that we want to activate an item on a frame
|
|
* instance that's not active. Since the frame has been instantiated, there
|
|
* must be a way to activate it. We just have to find out how.
|
|
*
|
|
* The first test eliminates the root frame. If we're at the root frame and
|
|
* still haven't figured out what to do, something is wrong and we give up.
|
|
*
|
|
* The next test skips references that are already right. Since we know that
|
|
* there must be at least one reference that leads elsewhere, and we haven't
|
|
* found it yet, the recursion will tell us whether it can find it at all.
|
|
*
|
|
* Finally, if we've found a mismatch, we correct it. We then try to fix any
|
|
* further mismatches. Since we've made progress, we return 1, even if the
|
|
* other fixes should fail (or reach the root frame).
