=============
2.21.3 - October 25, 2004
Corrected a silly bug in message translation which resulted in a small
performance loss. Simplified implementation of message sending predicate
::/2, resulting in a small performance improvement.
Added a new section on message sending performance to the user manual.
Added a new example, "benchmarks", for helping measuring performance of
Logtalk message sending between Prolog compilers and for comparing message
sending with predicate calls in plain Prolog and with calls to modules
predicates.
Updated the YAP configuration file to hide some of the book-keeping tables
of the Logtalk runtime engine and to use statistics/2 instead of cputime/0
for more accurate timings.
Updated the Logtalk shell installation script to create the $prefix/bin
directory if it does not exist.
The lgt2pdf.sh and lgt2html.sh shell scripts now use "rm -f" when removing
the DTD and XSD files in order to avoid prompting the the user about the file
permissions.
Updated the cplgtdirs.sh shell script to make all copied files user writable.
2.21.2 - October 18, 2004
Added support for declaring grammar rule non-terminals as public, protected,

Copyright (c) 1998-2004 Paulo Moura. All Rights Reserved.
=================================================================
To load all entities in this example compile and load the loader file:
| ?- logtalk_load(loader).
If your Prolog compiler does not support a module system, then edit the
loader.lgt file and comment out the directive that loads the module code.
In case your Prolog compiler supports a module system, you may need to
edit the code on the module.pl file and make any necessary compatibility
changes.
This folder provides simple benchmarks for comparing Logtalk message
sending performance with direct calls to Prolog predicates and with
calls to module predicates. These benchmarks may also be used for
comparing Logtalk message sending performance across Prolog compilers.
This example is made of four source files:
benchmark.pl
contains the benchmark predicates
plain.pl
contains a definition for a list length predicate
module.pl
contains the same definition of a list length predicate
encapsulated in a module
object.lgt
contains the same definition of a list length predicate
encapsulated in an object

@ -128,7 +128,7 @@ The current Logtalk implementation works as a pre-processor: Logtalk source file
As an object-oriented language, Logtalk uses dynamic binding for matching messages and methods. Furthermore, Logtalk entities (objects, protocols, and categories) are independently compiled, allowing for a very flexible programming development. Entities can be edited, compiled, and loaded at runtime, without necessarily implying recompilation of all related entities.
</p>
<p>
The Logtalk runtime engine implements caching of method lookups (including messages to self and super calls), ensuring a performance level close to what could be achieved with static binding implementations.
