Dear All,
We are happy to announce a new edition of
the Dogelog Player:
- Enhanced core (IEEE Comparisons):
The special value 0rNaN received comparison
drawn from IEEE. The built-in (=\=)/2 now
implements not quiet, while the built-ins
(=:=)/2, (<)/2, etc. now implement quiet.
The built-ins (@<)/2, etc. now implement
quiet ordered, while the built-ins min/3
and max/3 now implement number.
- Goal Inlining/Outlining:
We noticed performance problems of negation
as failure (\+)/2 when the argument is a
complex goal. Many Prolog systems don't
suffer from this problem. We implemented
a form of goal expansion, but with reversibility,
so that rewritten (\+)/2 calls are seen
again in listing/[0,1] and trace/0.
- Just-in-Time Indexing:
The scope is currently MAX_INDEX = 2
indiscriminantly for static and dynamic
predicates. The system can dynamically
allocate 1st or 2nd argument indexes when
needed, and even create combined 1st+2nd
argument indexes. The enhancement comes
with a new jiti_list/[0,1] utilitiy.
Have Fun!
