Re: ANN: Dogelog Player 1.3.0 (Graph Plotting)

Tired of pounding out the same old boring boilerplate
code over and over and over again. I'll show you how
to eliminate the boilerplate by using higher-order
programming: functions that take other functions as
arguments; or in Prolog, predicates that take other
predicates as arguments.
Somehow we shied away from implementing call/n for
our Prolog system. We thought our Prolog system has
only monomorphic predicate lookup caches and therefore
we kept a distance. This changed when we had the idea
to dynamically add a cache for the duration of a
higher order loop.
We could provide a new builtin call/n for our Prolog
system. Testing some list processing from different
angles we conclude our performance is middle field,
comparable to Scryer Prolog. This makes it feasible to
bring call/n and predicates such as maplist/n to the
upcoming release of Dogelog Player.

Dear All,
 We are happy to announce a new edition of
the Dogelog player:
 - Enhanced library(lists):
   We made the predicate free_variables/3 now public
in library(lists). It implements then ISO core standard
specification ISO 7.1.1.4 of witness variables. The
predicate does not appear in the Novacore kernel.
 - Enhanced library(sequence):
   As an alternative we provide a new predicate firstof/2.
The predicate is bootstraped from what is used in
distinct/1, but makes use of free_variables/3 to determine
the keys for deduplication during backtracking. Has more
logical properties than distinct/2.
 - New library(plot):
   The library(plot) can generate line plots in the form
of a SVG element. We currently provide the predicates
plot/1 and plot/2 which take a list of points (x,y1,..,yn)
and plot the lines (x,y1) ... (x,yn). The binary predicate
allows specifying various plot options.
 Have Fun!
