ANN: Dogelog Player 2.2.2 (Unified Tabling)

Date: May 01, 2026

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!
