GNU Prolog for Java 0.2.5 beta release

Item posted by Daniel Thomas <drt24> on Sun 15 Aug 2010 02:04:19 PM UTC.

The GNU Prolog for Java project is proud to announce the release of the beta version of our 0.2.5 release.
Prolog for Java is a java library (gnu.prolog) that allows Prolog code to be executed from within java. This allows for the use of Prolog to solve the problems which Prolog is particularly suited to while Java is used for other components.
It can be downloaded from or by ftp and is licensed under the LGPLv3.

The main change since alpha is that we now have a manual.

NEWS since the last release:

0.2.5 beta 2010-07-28
   Conforms to ISO/IEC DIS 13211-1 : 1995 bar two minor bugs.
   There is now a (texinfo) manual.
   The demo package now contains an example of the use of the API.
   The public key of the key signing key is in the sources.
   Term classes now have working .toString() functions (which use TermWriter.toString(Term))
   The Inria test suite provides an easily extensible test suite for testing standards
   This supplements the vanilla test suite both of which can be found here:
   NONISO features added:
       ensure_loaded/1 predicate can be used anywhere
       If ':- term' is used and term is not a directive then this will be treated as
         ':- intiailization(term)'.
       random(L) predicate evaluates to a random number i such that 0 =< i < L
   GNU Prolog for Java is now licensed under the LGPLv3 rather than the LGPLv2.
   Interpreter's context methods have been deprecated.
   The source now includes gnu.getopt
   The Interpreter#runOnce(Term) method added to simplify the case where the
   user only wishes to get the first answer from Prolog.
   Added NumericTerm as an abstract parent of FloatTerm and IntegerTerm
   Two outstanding bugs in standards compliance are:
       #30568 (inria tests on findall's throwing of type_errors fails) and
       #30335 (inria tests on arg's unification of variables inside the compound term fail)
   Other bugs
       #30630 Deadlock may occur if multiple threads operate on the same environment
       #30780 Unicode input breaks the parser (it gets stuck in an infinite loop).
   Michiel Hendriks wrote many additional features and added support for many more
   predicates as well as doing a lot of work towards ISO Prolog part 1 compliance.
   This includes: get_time/1, stamp_date_time/3, date_time_stamp/2, date_time_value/3,
   format_time/3, format_time/4, parse_time/2, parse_time/3, trace/0, notrace/0,
   tracing/0, spy/2, nospy/1, nospyall/0, various predicates for dialogs,
   java_to_string/2, java_classname/2, listing/0, listing/1, compare/3, stacktrace/1,
   current_functor/2, uuid/1, uuid/2, uuid_compare/3, uuid_version/2, uuid_variant/2
0.2.0 2009-03-04
   Various changes, bug fixes and additions.
   It now conforms to the "vanilla" test suite (with a few minor changes to some tests).
   All ISO Prolog predicates are supported. char_conversion is implemented but not used.
   Added support for tracing/spying predicates
