Logtalk - Object oriented extension to Prolog
|
||||
Release 2.28.2
|
||||
|
||||
Copyright (c) 1998-2006 Paulo Moura. All Rights Reserved.
|
||||
=================================================================
|
||||
|
||||
|
||||
This file contains detailed instructions for customizing your Logtalk
|
||||
installation and working environment. Customization is mostly done on
|
||||
a per-user basis by editing files on the Logtalk user folder (whose
|
||||
path is sorted on the LOGTALKUSER environment variable).
|
||||
|
||||
|
||||
1. SETTING LIBRARY PATHS
|
||||
|
||||
In Logtalk, a library is simply a directory containing source files. Library
|
||||
paths can be declared using a dynamic predicate. This allows compiling and
|
||||
loading of libraries and library files to be performed without worries about
|
||||
library paths.
|
||||
|
||||
Inside your Logtalk user folder, you will find a "libpaths" folder containing
|
||||
a sample file which, when loaded, defines the library paths for the Logtalk
|
||||
standard library and for all the supplied examples. This file may need to be
|
||||
edited to match both your Logtalk installation and your Prolog compiler and
|
||||
operating-system requirements. For details, see the file "libpaths/NOTES".
|
||||
|
||||
|
||||
2. CUSTOMIZING PROLOG CONFIGURATION FILES
|
||||
|
||||
Logtalk interfaces with a specific Prolog compiler via a configuration file
|
||||
that can be found on the "configs" folder inside your Logtalk user folder.
|
||||
These configuration files can be customized by changing the values of the
|
||||
default flags that are used by Logtalk when compiling source files. For a
|
||||
full description of these default flags, consult the "Running and debugging
|
||||
Logtalk programs" section of the User Manual. Some of the default flags that
|
||||
you may want to change include: "smart_compilation", "startup_message",
|
||||
"portability", "underscore_vars", "altdirs", and the set of documentation-
|
||||
related flags ("xmldocs", "xslfile", "xmlspec", and "xmlsref"). Be sure to
|
||||
read the "configs/NOTES" file for Prolog specific notes; some Prolog compilers
|
||||
do not support the whole range of compilation flag values.
|
||||
|
||||
|
||||
3. CUSTOMIZING DOCUMENTATION PROCESSING SCRIPTS AND SUPPORTING FILES
|
||||
|
||||
Inside your Logtalk user folder, you will find a "xml" folder containing a
|
||||
set of shell scripts, CSS and XSLT style-sheets, and DTD and XML Schema files
|
||||
for processing the XML documenting files that are automatically generated
|
||||
when you compile source files. You may want to customize the CSS and XSLT
|
||||
files to modify the layout or style of the resulting PDF/(X)HTML files or to
|
||||
write new scripts and transformations to generate other formats. You may also
|
||||
edit the file "custom.ent" in order to specify XML entities for your personal
|
||||
data that can be used on Logtalk documenting directives. For details, see the
|
||||
file "xml/NOTES".
|
||||
|
||||
|
||||
4. ADDING SUPPORT FOR EDITING LOGTALK SOURCE FILES TO TEXT EDITORS
|
||||
|
||||
Inside your Logtalk user folder, you will find a "wenv" folder, containing
|
||||
configuration files for several text editors, which add support for syntax
|
||||
coloring and other editing services of Logtalk source files. For details,
|
||||
see the file "wenv/NOTES".

5. SETTING LIBRARY PATHS
|
||||
5. CUSTOMIZING LOGTALK
|
||||
|
||||
In Logtalk, a library is simply a directory containing source files. Library
|
||||
paths can be declared using a dynamic predicate. This allows compiling and
|
||||
loading of libraries and library files to be performed without worries about
|
||||
library paths. Assuming that you have used the "scripts/cplgtdirs.*" shell
|
||||
scripts for making a copy of the user-modifiable Logtalk files, you will find
|
||||
in the "$LOGTALKUSER/libpaths" directory a sample file which, when loaded,
|
||||
defines the library paths for the Logtalk standard library and for all the
|
||||
supplied examples. This file may need to be edited to match your Logtalk
|
||||
installation and your Prolog compiler and operating-system requirements. For
|
||||
more details, see the file "$LOGTALKUSER/libpaths/NOTES".
|
||||
|
||||
|
||||
6. CUSTOMIZING PROLOG CONFIGURATION FILES
|
||||
|
||||
Logtalk interfaces with a specific Prolog compiler via a configuration file
|
||||
that can be found on the "$LOGTALKUSER/configs" directory. These configuration
|
||||
files can be customized by changing the values of the default flags that are
|

used by Logtalk when compiling source files. For a full description of these
|
||||
default flags, consult the "Running and debugging Logtalk programs" section of
|
||||
the User Manual. Some of the default flags that you may want to change are:
|
||||
"smart_compilation", "startup_message", "portability", "underscore_vars",
|
||||
"altdirs", and the set of documentation-related flags ("xmldocs", "xslfile",
|
||||
"xmlspec", and "xmlsref"). Be sure to read the "$LOGTALKUSER/configs/NOTES"
|
||||
file for Prolog specific notes; some Prolog compilers do not support the whole
|
||||
range of compilation flag values.
|
||||
|
||||
|
||||
7. CUSTOMIZING DOCUMENTATION PROCESSING SCRIPTS AND SUPPORTING FILES
|
||||
|
||||
Logtalk provides, in the "$LOGTALKUSER/xml" directory, a set of shell scripts,
|
||||
CSS and XSLT style-sheets, and DTD and XML Schema files for processing the XML
|
||||
documenting files that are automatically generated when you compile source
|
||||
files. You may want to customize these CSS and XSLT files to modify the layout
|
||||
or style of the resulting PDF/(X)HTML files or to write new scripts and
|
||||
transformations to generate other formats. For more details, see the file
|
||||
"$LOGTALKUSER/xml/NOTES".
|
||||
Please see the file "CUSTOMIZE.txt" for details on how to customize your

||||
Logtalk installation and working environment.

Preamble
|
||||
|
||||
This copyright license states the terms under which a given free software
|
||||
Package may be copied, modified and/or redistributed, while the
|
||||
Originator(s) maintain some artistic control over the future development of
|
||||
that Package (at least as much artistic control as can be given under
|
||||
copyright law while still making the Package open source and free software).
|
||||
|
||||
This license is bound by copyright law, and thus it legally applies only to
|
||||
works which the copyright holder has permitted copying, distribution or
|
||||
modification under the terms of the Artistic License, Version 2.0.
|
||||
|
||||
You are reminded that You are always permitted to make arrangements wholly
|
||||
outside of a given copyright license directly with the copyright holder(s)
|
||||
of a given Package. If the terms of this license impede your ability to
|
||||
make full use of the Package, You are encouraged to contact the copyright
|
||||
holder(s) and seek a different licensing arrangement.
|
||||
|
||||
|
||||
Definitions
|
||||
|
||||
"Package" refers to the collection of files distributed by the
|
||||
Originator(s), and derivatives of that collection of files created
|
||||
through textual modification.
|
||||
|
||||
"Standard Version" refers to the Package if it has not been modified, or has
|
||||
been modified only in ways suggested by the
|
||||
Originator(s).
|
||||
|
||||
"Modified Version" refers to the Package, if it has been changed by You via
|
||||
textual modification of the source code, and such changes
|
||||
were not suggested by the Originator(s).
|
||||
|
||||
"Originator" refers to the author(s) and/or copyright holder(s) of the
|
||||
Standard Version of the Package.
|
||||
|
||||
"You" and "Your" refers to any person who would like to copy, distribute, or
|
||||
modify the Package.
|
||||
|
||||
"Distribution Fee" is any fee that You charge for providing a copy of this
|
||||
Package to another party. It does not refer to licensing
|
||||
fees.
|
||||
|
||||
"Freely Available" means that:
|
||||
|
||||
(a) no fee is charged for the right to use the item (though a
|
||||
Distribution Fee may be charged).
|
||||
|
||||
(b) recipients of the item may redistribute it under the same
|
||||
conditions they received it.
|
||||
|
||||
(c) If the item is a binary, object code, bytecode, the complete
|
||||
corresponding machine-readable source code is included with the
|
||||
item.
|
||||
|
||||
|
||||
Permission for Use and Modification Without Redistribution
|
||||
|
||||
(1) You are permitted to use the Standard Version and create and use
|
||||
Modified Versions for any purpose without restriction, provided that
|
||||
you do not redistribute the Modified Version to others outside of your
|
||||
company or organization.
|
||||
|
||||
|
||||
Permissions for Redistribution of the Standard Version
|
||||
|
||||
(2) You may make available verbatim copies of the source code of the
|
||||
Standard Version of this Package in any medium without restriction,
|
||||
either gratis or for a Distribution Fee, provided that you duplicate
|
||||
all of the original copyright notices and associated disclaimers. At
|
||||
Your discretion, such verbatim copies may or may not include compiled
|
||||
bytecode, object code or binary versions of the corresponding source
|
||||
code in the same medium.
|
||||
|
||||
(3) You may apply any bug fixes, portability changes, and other
|
||||
modifications made available from any of the Originator(s). The
|
||||
resulting modified Package will still be considered the Standard
|
||||
Version, and may be copied, modified and redistributed under the terms
|
||||
of the original license of the Standard Version as if it were the
|
||||
Standard Version.
|
||||
|
||||
|
||||
Permissions for Redistribution of Modified Versions of the Package as Source
|
||||
|
||||
(4) You may modify your copy of the source code of this Package in any way
|
||||
and distribute that Modified Version (either gratis or for a
|
||||
Distribution Fee, and with or without a corresponding binary, bytecode
|
||||
or object code version of the Modified Version) provided that You
|
||||
clearly indicate what changes You made to the Package, and provided
|
||||
that You do at least ONE of the following:
|
||||
|
||||
(a) make the Modified Version available to the Originator(s) of the
|
||||
Standard Version, under the exact license of the Standard
|
||||
Version, so that the Originator(s) may include your modifications
|
||||
into the Standard Version (at their discretion).
|
||||
|
||||
(b) modify any installation scripts and procedures so that
|
||||
installation of the Modified Version will never conflict with an
|
||||
installation of the Standard Version, include for each program
|
||||
installed by the Modified Version clear documentation describing
|
||||
how it differs from the Standard Version, and rename your
|
||||
Modified Version so that the name is substantially different from
|
||||
the Standard Version.
|
||||
|
||||
(c) permit and encourage anyone who receives a copy of the Modified
|
||||
Version to make your modifications Freely Available in some
|
||||
specific way.
|
||||
|
||||
If Your Modified Version is in turn derived from a Modified Version
|
||||
made by a third party, then You are still required to ensure that Your
|
||||
Modified Version complies with the requirements of this license.
|
||||
|
||||
|
||||
Permissions for Redistribution of Non-Source Versions of Package
|
||||
|
||||
(5) You may distribute binary, object code, bytecode or other non-source
|
||||
versions of the Standard Version of the Package, provided that you
|
||||
include complete instructions on where to get the source code of the
|
||||
Standard Version. Such instructions must be valid at the time of Your
|
||||
distribution. If these instructions, at any time while You are
|
||||
carrying our such distribution, become invalid, you must provide new
|
||||
instructions on demand or cease further distribution. If You cease
|
||||
distribution within thirty days after You become aware that the
|
||||
instructions are invalid, then You do not forfeit any of Your rights
|
||||
under this license.
|
||||
|
||||
(6) You may distribute binary, object code, bytecode or other non-source
|
||||
versions of a Modified Version provided that You do at least ONE of
|
||||
the following:
|
||||
|
||||
(a) include a copy of the corresponding source code for the Modified
|
||||
Version under the terms indicated in (4).
|
||||
|
||||
(b) ensure that the installation of Your non-source Modified Version
|
||||
does not conflict in any way with an installation of the Standard
|
||||
Version, include for each program installed by the Modified
|
||||
Version clear documentation describing how it differs from the
|
||||
Standard Version, and rename your Modified Version so that the
|
||||
name is substantially different from the Standard Version.
|
||||
|
||||
(c) ensure that the Modified Version includes notification of the
|
||||
changes made from the Standard Version, and offer to provide
|
||||
machine-readable source code (under a license that permits making
|
||||
that source code Freely Available) of the Modified Version via
|
||||
mail order.
|
||||
|
||||
|
||||
Permissions for Inclusion of the Package in Aggregate Works
|
||||
|
||||
(7) You may aggregate this Package (either the Standard Version or
|
||||
Modified Version) with other packages and distribute the resulting
|
||||
aggregation provided that You do not charge a licensing fee for the
|
||||
Package. Distribution Fees are permitted, and licensing fees for
|
||||
other packages in the aggregation are permitted. Your permission to
|
||||
distribute Standard or Modified Versions of the Package is still
|
||||
subject to the other terms set forth in other sections of this
|
||||
license.
|
||||
|
||||
(8) In addition to the permissions given elsewhere by this license, You
|
||||
are also permitted to link Modified and Standard Versions of this
|
||||
Package with other works and distribute the result without
|
||||
restriction, provided You have produced binary program(s) that do not
|
||||
overtly expose the interfaces of the Package. This includes
|
||||
permission to embed the Package in a larger work of your own without
|
||||
exposing a direct interface to the Package. This also includes
|
||||
permission to build stand-alone binary or bytecode versions of your
|
||||
scripts that require the Package, but do not otherwise give the casual
|
||||
user direct access to the Package itself.
|
||||
|
||||
|
||||
Items That are Never Considered Part of a Modified Version Package
|
||||
|
||||
(9) Works (including, but not limited to, subroutines and scripts) that
|
||||
you have linked or aggregated with the Package that merely extend or
|
||||
make use of the Package, but are not intended to cause the Package to
|
||||
operate differently from the Standard Version, do not, by themselves,
|
||||
cause the Package to be a Modified Version. In addition, such works
|
||||
are not considered parts of the Package itself, and are not bound by
|
||||
the terms of the Package's license.
|
||||
|
||||
|
||||
Acceptance of License and Disclaimer of Warranty
|
||||
|
||||
(10) You are not required to accept this License, since you have not signed
|
||||
it. However, nothing else grants you permission to copy, modify or
|
||||
distribute the Standard or Modified Versions of the Package. These
|
||||
actions are prohibited by copyright law if you do not accept this
|
||||
License. Therefore, by copying, modifying or distributing Standard
|
||||
and Modified Versions of the Package, you indicate your acceptance of
|
||||
the license of the Package.

||||
|
||||
|
||||

=============
|
||||
|
||||
|
||||
2.28.2 - November 6, 2006
|
||||
|
||||
Corrected a compiler bug where unknown entities will not be report when
|
||||
compiling a source file whenever an entity with the same name but of a
|
||||
different type is already known.
|
||||
|
||||
Added a XPCE hook file ("configs/xpcehook.pl") supporting Logtalk message
|
||||
sending goals as XPCE call-back goals. The XPCE library is now loaded by
|
||||
default by the SWI-Prolog integration scripts.
|
||||
|
||||
Added support for generating single PDF files of the User and Reference
|
||||
Manuals. Removed the PDF versions of the individual manual XHTML pages.
|
||||
|
||||
The ECLiPSe config files now require release 5.10#26 or a later version.
|
||||
|
||||
Added support for listing Logtalk entity names (objects, categories, and
|
||||
protocols) in the SubEthaEdit symbols menu.
|
||||
|
||||
Added a Vim dictionary file for Logtalk keyword completion and support
|
||||
for automatic indentation.
|
||||
|
||||
Added basic support for the MacOS X Smultron text editor. Added basic
|
||||
support for the Notepad++, SuperEdi, and ConTEXT Windows text editors.
|
||||
|
||||
|
||||
2.28.1 - October 10, 2006
|
||||
|
||||
Added support for using XML entities using the notation "{entity name}"
|
||||
in info/1 documenting directives for the "author", "copyright", and
|
||||
"license" keywords. The XML entities are defined on a "custom.ent" file.
|
||||
|
||||
Updated Logtalk bibliographic references (in file "BIBLIOGRAPHY.bib").
|
||||
|
||||
Added a "lgt_uninstall.sh" shell script for uninstalling Logtalk on POSIX
|
||||
operating systems.
|
||||
|
||||
Improved RPM install-time messages on the defined Logtalk environment
|
||||
variables.
|
||||
|
||||
Updated the ECLiPSe integration scripts and config files to work with
|
||||
and require version 5.10 (the first open source version of ECLiPSe).
|
||||
|
||||
Corrected a typo on the "logtalk.dtd" file that prevents validation of
|
||||
XML documenting files that use a local reference to the DTD.
|
||||
|
||||
|
||||
2.28.0 - September 28, 2006
|
||||
|
||||
Updated the Logtalk license to the final version of the "The Artistic
|
||||
License 2.0" (see http://www.perlfoundation.org/legal/ for details).
|
||||
|
||||
Added experimental support for multi-threading programming on selected
|
||||
Prolog compilers. Added a new object directive, threaded/0, a new
|
||||
predicate directive, atomic/1, and four new built-in predicates,
|
||||
threaded_call/1-2 and threaded_exit/1-2. Added a new set of examples,
|
||||
"threads". Thanks to Paulo Nunes for helping developing and testing
|
||||
these new features.
|
||||
|
||||
Expanded support for meta-predicates by allowing the declaration of meta-
|
||||
arguments as closures instead of goals.
|
||||
|
||||
Added the generalized call/N predicate as a built-in method. This built-in
|
||||
method must be used in the implementation of meta-predicates which work
|
||||
with closures instead of goals.
|
||||
|
||||
The metapredicate/1 directive should be considered deprecated. Use the
|
||||
meta_predicate/1 directive instead.
|
||||
|
||||
Updated the Logtalk compiler to generate an error whenever a non-variable
|
||||
meta-argument is found in a clause head of a user-defined meta-predicate.
|
||||
|
||||
Improved compilation of meta-predicate meta-arguments. Corrected a bug
|
||||
in the compilation of user meta-predicates that allowed illegal calls
|
||||
to non-public predicates on the caller object to be made from the object
|
||||
defining the meta-predicates. Thanks to Rémy Haemmerlé and François
|
||||
Fages for reporting the problem.
|
||||
|
||||
Improved performance for non-cached messages, notably when running with
|
||||
YAP, GNU Prolog, and SWI-Prolog on all operating systems and with SICStus
|
||||
Prolog 4.0 on POSIX operating systems.
|
||||
|
||||
Updated the Logtalk compiler to generate an error whenever a predicate
|
||||
directive appears in a source file after predicate clauses that call the
|
||||
predicate specified in the directive.
|
||||
|
||||
Added support for "copyright" and "license" keys to the info/1 entity
|
||||
documenting directive.
|
||||
|
||||
Improved compiler error messages to also report source file line number
|
||||
for selected Prolog compilers.
|
||||
|
||||
Added PDF versions of all the manual XHTML pages. Added links to all the
|
||||
manual XHTML pages to the corresponding PDF versions.
|
||||
|
||||
Corrected a bug (introduced in version 2.27.0) in the built-in predicates
|
||||
abolish_object/1, abolish_protocol/1, and abolish_category/1 that resulted
|
||||
in some clauses not being retracted when an object is abolished (thanks to
|
||||
Neng-Fa Zhou for the bug report).
|
||||
|
||||
Corrected a bug (introduced in version 2.27.1) in the processing of the
|
||||
term_expansion/2 predicate.
|
||||
|
||||
Corrected a bug in the compilation of redefined built-in predicates with
|
||||
no clauses.
|
||||
|
||||
Added an experimental config file for CxProlog 0.93.1.
|
||||
|
||||
Updated the SWI-Prolog config and hook files in order to support the
|
||||
edit/1 and make/0 development predicates.
|
||||
|
||||
Changed the Logtalk - SWI-Prolog integration scripts to load the hook
|
||||
file "swihook.pl" after the other files in order to avoid some possible
|
||||
errors at startup.
|
||||
|
||||
Updated the config file for the forthcoming SICStus Prolog 4.0 version
|
||||
to work in the current beta version. Modified the "make_sicstuslgt.*"
|
||||
shell scripts to work with both SICStus Prolog 3.12 and 4.0 versions.
|
||||
|
||||
Updated the config file for YAP to workaround a problem on the Windows
|
||||
version where testing for directory existence fails if the path ends with
|
||||
a slash (or a double backslash); this problem prevents the use of library
|
||||
notation to load source files (problem already fixed in the current YAP
|
||||
CVS version).
|
||||
|
||||
Updated the config file for B-Prolog to match (and require) the new 6.9
|
||||
version; added integration shell scripts (for both Windows and POSIX
|
||||
systems).
|
||||
|
||||
Updated the config files and the integration scripts for ECLiPSe in order
|
||||
to workaround bugs on the predicates abolish/1 and canonical_path_name/2.
|
||||
Modified the "make_eclipselgt.js" script to work with both ECLiPSe 5.8
|
||||
and 5.9 versions.
|
||||
|
||||
Dropped support for versions of XSB older than 3.0. Added support for
|
||||
smart compilation of source files to the XSB config file.
|
||||
|
||||
Updated the config file for IF/Prolog 5.1 by adding a missing definition
|
||||
for predicate retractall/1 and avoiding some harmless singleton warnings.
|
||||
|
||||
Add a ".txt" extension to all "NOTES" and "SCRIPT" files.
|
||||
|
||||
Extended "dcgs", "parametric", and "metainterpreters" examples.
|
||||
|
||||
Added Inno Setup GUI Windows installer script.
|
||||
|
||||
Update all the JScript scripts to check if a compatible version of WSH
|
||||
is installed and to workaround some problems with spaces in file paths.
|
||||
|
||||
Updated the "lgt_install.js" JScript script to copy the scripts/*.bat and
|
||||
the xml/*.bat batch scripts to the system's Windows directory instead of
|
||||
modifying the PATH environment variable.
|
||||
|
||||
Updated the "cplgtdirs.*" shell scripts to make a backup copy of any
|
||||
previous LOGTALKUSER directory.
|
||||
|
||||
Added post-install scripts to the LINUX RPM "logtalk.spec" file for
|
||||
setting the environment variable LOGTALKHOME for all users, defining
|
||||
a default value for the environment variable LOGTALKUSER, and running
|
||||
the Prolog integration scripts.
|
||||
|
||||
Split the installation and customization instructions in two files,
|
||||
"INSTALL.txt" and "CUSTOMIZE.txt".
|
||||
|
||||
Added shell scripts for converting the manual XHTML pages into PDF files
|
||||
using CSSToXSLFO.
