ANN: Logtalk 3.00.0 Release Candidate 1 now available

[apologies in case of multiple receptions]

Hi,

Logtalk 3.00.0 Release Candidate 1 is now available for downloading at:

http://logtalk.org/

Logtalk is an object-oriented logic programming language that extends and 
leverages the Prolog language with a feature set suitable for programming in 
the large. Written in highly portable code, it can use most modern Prolog 
implementations as a back-end compiler. As a multi-paradigm language, it 
includes support for both prototypes and classes, protocols (interfaces), 
categories (components), event-driven programming, and high-level 
multi-threading programming. Its distribution includes full documentation, 
portable libraries, a comprehensive set of portable developer tools, and a 
large number of programming examples to help get you started.

Logtalk can also be used as a highly portable layer on top of Prolog, as a 
Prolog library used together other libraries, and as a porting tool. It 
subsumes Prolog modules by both being able to compile modules as objects and by 
providing a portable implementation of the de facto common core Prolog module 
features.

Developer tool highlights include a unit testing framework supporting full code 
coverage at the clause level and determinism tests; a sophisticated diagramming 
tool able to illustrate library, entity, and predicate relations; a documenting 
tool capable of of generating API documentation in e.g. HTML and PDF; and a 
port profiler tool for performance analysis of actual predicate execution.

This is a near final release of the third generation of Logtalk. Only 
documentation and bug fixes are expected before the final, stable, release, 
which is expected later this month. Interested parties are invited to test 
their applications, specially if migrating from Logtalk 2.x.

This release fixes long standing meta-predicate execution context issues 
inherited from Logtalk 2.x, improves meta-predicate semantics by ensuring that 
meta-arguments are always called with the caller full execution context, 
refines and improves multifile predicate semantics, adds a new token to the 
structured message printing mechanism, features a new port profiler tool, 
improves the debugger and diagrams tools, fixes all known bugs, includes 
documentation and unit test updates, and SWI-Prolog, XSB, and YAP compatibility 
improvements. For details and a complete list of changes, please consult the 
release notes at:

Happy logtalking!
