4. CREATING NEW PROLOG TOP-LEVELS FOR AUTOMATIC LOADING OF LOGTALK
|
||||
|
||||
Most Prolog compilers allows the user to define an initialization file that
|
||||
is automatically consulted at startup. This initialization file may contain
|
||||
directives for loading other files, such as the Logtalk configuration file
|
||||
and the Logtalk compiler. The "$LOGTALKHOME/scripts" sub-directory contains
|
||||
several scripts (named "make_*lgt.*") for automating the creation of these
|
||||
initialization files for some Prolog compilers. In addition, be sure to read
|
||||
the "configs/NOTES.txt" file notes on the Prolog compilers that you intend to
|
||||
use. There are also "makeall_lgt.*" scripts that try to run all the individual
|
||||
"make_*lgt.*" scripts:
|
||||
|
||||
>> POSIX systems:
|
||||
|
||||
% cd $LOGTALKHOME/scripts
|
||||
% sudo ./makeall_lgt.sh
|
||||
|
||||
>> Windows:
|
||||
|
||||
C:\> cd %LOGTALKHOME%\scripts
|
||||
C:\> cscript makeall_lgt.js
|
||||
|
||||
This assumes that your favorite Prolog compilers are supported by the
|
||||
"make_*lgt.*" scripts. If that is not the case, don't worry: just follow
|
||||
the steps described in the "QUICK_START.txt" file.
|
||||
Most Prolog compilers allows the user to define an initialization file
|
||||

|
||||

|
||||
sub-directory contains several pre-made scripts (named "*lgt.*") for running
|
||||
Logtalk with selected back-end Prolog compilers. You can use these scripts
|
||||
as examples when creating initialization files for other Prolog compilers.
|
||||
Be sure to read the "configs/NOTES.txt" file notes on the Prolog compilers
|
||||
that you intend to use. You may also simply follow the steps described in

RELEASE NOTES
|
||||
=============
|
||||
|
||||
|
||||
2.30.1 - June 12, 2007
|
||||
|
||||
Added a new, experimental control construct, :/1, for calling imported
|
||||
category predicates without using message sending mechanisms.
|
||||
|
||||
Added preliminary support for static binding when calling imported
|
||||
category using the new :/1 control construct for categories compiled
|
||||
and loaded using the compiler option "reload(skip)".
|
||||
|
||||
Added a new control construct, <</2, which allows proving a goal within
|
||||
the context of a specified object. Useful for debugging and for writing
|
||||
object unit tests.
|
||||
|
||||
Improved multi-threading support in order to make the built-in predicate
|
||||
threaded_exit/1 generate an exception instead of blocking indefinitely
|
||||
waiting for a reply from a non-existing thread.
|
||||
|
||||
Updated the Logtalk compiler to generate an error when compiling from a
|
||||
source file new definitions for built-in entities.
|
||||
|
||||
Updated the Logtalk compiler to generate simpler clauses for the book-
|
||||
keeping table of local predicate definitions for parametric entities.
|
||||
|
||||
Updated the config files for ECLiPSe, Ciao Prolog, SICStus Prolog,
|
||||
SWI-Prolog, and YAP to use the renamed hook predicates introduced in
|
||||
Logtalk 2.30.0 for parsing Prolog proprietary directives.
|
||||
|
||||
Updated the "benchmarks" example to compare the performance of calls to
|
||||
imported category predicates when using a message to "self" and a direct
|
||||
call.
|
||||
|
||||
|
||||
2.30.0 - May 28, 2007
|
||||
|
||||
Added preliminary support for static binding when sending messages to
|
||||
objects compiled and loaded using the compiler option "reload(skip)".
|
||||
|
||||
Allow non-instantiated arguments at compile time for the multi-threading
|
||||
built-in predicate threaded/1.
|
||||
|
||||
Simplified and optimized the implementation of Logtalk multi-threading
|
||||
support. Use a single dispatcher thread for all objects instead of each
|
||||
object running its own dispatcher in order to minimize the number of
|
||||
created threads (which can be problematic on 32 bits systems). Updated
|
||||
the built-in predicate threaded/1 to make it deterministic and opaque to
|
||||
cuts (similar to once/1).
|
||||
|
||||
Updated the Logtalk built-in database methods to always interpret rules
|
||||
whose body is the control construct true/0 as facts. Corrected a bug when
|
||||
compiling dynamic predicates that would prevent using of the clause/2
|
||||
built-in database method. Corrected a bug when using the Logtalk built-in
|
||||
database method clause/2 with entities compiled in debug mode. Improved
|
||||
predicate lookup caching when asserting and retracting dynamic facts.
|
||||
|
||||
Improved detection and reporting of entity existence errors.
|
||||
|
||||
Added a quit option, "q", to the Logtalk built-in debugger. Modified
|
||||
the debugger behavior to automatically switch to trace mode when a spy
|
||||
point is found.
|
||||
|
||||
Added two new compiler options, "xmldir" and "tmpdir", allowing per
|
||||
project definition of directories for storing XML documenting files
|
||||
and for storing intermediate compilation files (e.g. Prolog files).
|
||||
Removed the config file predicate '$lgt_alt_directory'/2.
|
||||
Older config files are incompatible with this new Logtalk version.
|
||||
|
||||
Added a shortcut to the Logtalk built-in predicate logtalk_load/1, {}/1,
|
||||
to all config files (defined there in order to be easy to comment it out
|
||||
in case of conflict with some Prolog native feature or lack of compliance
|
||||
with the ISO Prolog standard regarding the definition of the {}/1 syntax.
|
||||
|
||||
Allow the compiler flag "misspelt" to be set to "error".
|
||||
|
||||
Updated the Logtalk compiler to not try to clean-up the dynamic predicates
|
||||
of redefined entities when reloading source files. Most Prolog compilers
|
||||
already behave as expected when reloading the intermediate Prolog files
|
||||
generated by the Logtalk compiler. For those Prolog compilers that do not
|
||||
replace old definitions for dynamic predicates with the new ones, it is
|
||||
not possible for Logtalk to implement a workaround that would work
|
||||
correctly in all cases. Consult the "configs/NOTES.txt" file for more
|
||||
information.
|
||||
|
||||
Corrected a bug that prevents abolishing a dynamic entity loaded from a
|
||||
source file. Thanks to Victor Noel for the bug report.
|
||||
|
||||
Renamed the '$lgt_copy_pl_directive'/1 and '$lgt_rewrite_pl_directive'/2
|
||||
config files predicates to '$lgt_rewrite_and_copy_pl_directive'/2 and
|
||||
'$lgt_rewrite_and_recompile_pl_directive'/2.
|
||||
|
||||
Updated the config file for B-Prolog to match (and require) the new 7.0
|
||||
version; updated and simplified the corresponding integration scripts.
|
||||
|
||||
Updated the XSB POSIX integration script to automatically detect if we
|
||||
are running the XSB stable version of the XSB CVS version.
|
||||
|
||||
Added basic support for tabling to the config files of B-Prolog, XSB,
|
||||
and YAP. Added a simple example of using tabling directives within
|
||||
objects.
|
||||
|
||||
Updated the SWI-Prolog and YAP config files to automatically detect if
|
||||
the Prolog systems have been compiled with multi-threading support and
|
||||
to set the Logtalk compiler flag "threads" accordingly.
|
||||
|
||||
Corrected a bug when running Logtalk with SWI-Prolog that prevented the
|
||||
use of alternative compilation directories (i.e. turning on the "altdirs"
|
||||
compiler flag). Corrected a bug when running Logtalk with SWI-Prolog that
|
||||
can prevent make/0 from recompiling and reloading modified Logtalk source
|
||||
files. Updated the SWI-Prolog integration script, "swilgt.sh", to more
|
||||
reliably detect the compiler executable name.
|
||||
|
||||
Added a "configs/swi_set_logtalk_context.pl" file defining a useful but
|
||||
fragile hack implementing a set_logtalk_context/1 built-in predicate for
|
||||
switching the Logtalk top-level execution context to objects other than
|
||||
the default pseudo-object "user" (you may use it as a debugging tool).
|
||||
|
||||
Updated the CxProlog config file to use the new built-in predicates in
|
||||
version 0.95. Added a shell script, "cxlgt.sh", for easy integration of
|
||||
Logtalk with CxProlog on POSIX systems (with the help of Artur Miguel
|
||||
Dias, CxProlog author).
|
||||
|
||||
Updated the Ciao, K-Prolog, and ECLiPSe config files to set the default
|
||||
value for the compiler flag "underscore_vars" to "dont_care" in order to
|
||||
avoid spurious warnings with some of the provided examples.
|
||||
|
||||
Added a config file and integration scripts for the current XSB CVS
|
||||
version (3.0.1+), which supports some features needed by Logtalk not
|
||||
present in the current stable version (namely, expansion of environment
|
||||
variables).
|
||||
|
||||
Added predicates depth/2 and variant/2 to the library object "term".
|
||||
|
||||
Much improved "benchmarks" example, updated to allow running tests in
|
||||
three different scenarios: event support on, event support off, and
|
||||
using static binding. Moreover, metacalls are no longer used to run
|
||||
the benchmark goals, resulting in more meaningful and accurate results.
|
||||
|
||||
Removed all the "make_*lgt.*" and "makeall_lgt.*" shell scripts, replaced
|
||||
by pre-made integration scripts that can be found on the new "integration"
|

Updated the "build_release.sh" POSIX shell script to also build a Debian

The Windows GUI installer no longer spans command-line shells running

You may have noticed above that the benchmark predicates and the predicates

for plain Prolog testing are both encapsulated in Logtalk source files. The

Logtalk compiler just copies the plain Prolog code to the generated Prolog

By default, the benchmark tests on the SCRIPT file use a list of 30 elements
|

as an argument to the list length predicates. Increasing the list length
|

leads to decreasing performance differences between plain Prolog and Logtalk

as the list length computation time far outweighs the overhead of the message
|

sending mechanism. Likewise, decreasing the list length leads to increasing
|
||||
performance differences between plain Prolog and Logtalk (up to the point you
|
||||
will be measuring the Logtalk message sending mechanism overhead compared to
|
||||
plain Prolog predicate calls). In real-life applications, only testing can
|
||||
give you a balanced view on the trade-offs between plain Prolog performance
|
||||
and Logtalk programming features.

By default, the benchmark tests on the SCRIPT file use a list of 20 elements

the code on the module.pl file to make any necessary compatibility changes

for your Prolog compiler module system. For most Prolog module systems, the

performance of module calls is close or even identical to the performance of

|

When using explicit module qualification, performance can be significantly

worse.
|
||||
|
||||
When static binding is used, messages to objects are, whenever possible,
|
||||
translated to direct predicate calls. Thus performance should be about the
|

same as in plain Prolog predicate calls. However, due to the overhead of
|

three extra arguments per object predicate (used for passing the execution

worse than the equivalent plain Prolog predicate calls.
