Dear All,

We are happy to announce a new edition
of the Dogelog Player:

- Tabling Directive:
It turns out that our term expansion is fit
enough to provide a tabling directive table/1.
The directive will prepare a query and a answer
cache for the given predicate, as well as a
wrapper. The current version does not yet
realize tabling of non-wellfounded recursion.

- Hash Indexes:
The tabling does not use a table space separate
from the dynamic database, instead the caches
are realized through dynamic predicates. To
profit even more from our ground term sharing,
we now offer pre-computed hash indexes. For
large ground terms, the tabling mechanism
can then exhibit emergent local interning.

- Rubber Band:
The format/[2,3] predicates got a facelift and
we now support the rubber band ~`Ct and the
column margin ~N|. The challenge was to keep
the streaming behaviour, which we could keep
for the first rubber band separated segment.
A further challenge was scattering character
richtext, which the format specifiers
~defgq can produce.

Have Fun!
