Baixar Logtalk 3.52.0 per a Windows

Logtalk compiler and runtime
- CHANGED: A partial list of terminals in the first argument of a grammar rule body to generate an instantiation error as per the standardization proposal.
- IMPROVED: Generalized the linter checks for is/2 and (=:=)/2 goals to cases where the expression arguments are not ground but their type can be inferred.
- FIXED: Processing of conditional compilation directives in included files.
- FIXED: Duplicated linter warnings for some DEC-10 Prolog I/O predicates.
- FIXED: The pack library paths to always end with a slash.
- FIXED: Explicit messages to the user pseudo-object when the predicate being called is a meta-predicate.
- FIXED: Avoid a warning when embedding Logtalk due to the definition of the forward/1 predicate in the user pseudo-object.

Prolog adapter and integration files
- UPDATED: The LVM adapter file to require version 2.0.0 or later.
- UPDATED: The Trealla Prolog adapter file to require version 1.16.6 or later.
- UPDATED: The Tau Prolog adapter file to require version 0.3.1 or later.
- FIXED: The Trealla Prolog integration script to support "-- Arguments" passed by other scripts (e.g. logtalk_tester script) that call it.
- FIXED: The GNU Prolog adapter file to allow the consult/1 built-in predicate to be called from within objects and categories without requiring overriding its meta-predicate template.
- FIXED: The YAP adapter file definition of the internal predicate '$lgt_load_prolog_file'/1.

Documentation
- ADDED: Section on creating and using virtual environments to the packs tool documentation.
- IMPROVED: Documentation of the logtalk built-in object trace_event/2 and debug_handler/2 predicates.
- IMPROVED: Man pages of the integration scripts.
- IMPROVED: Documentation on using the lgtunit tool QuickCheck support.
- UPDATED: The documentation of the logtalk_library_path/2 predicate for the logtalk_packs library alias.
- UPDATED: The settings-sample.lgt with sample code for defining the new logtalk_packs library alias.
- FIXED: The update_html_docs.sh and update_svg_diagrams.sh scripts to work with all supported backends.

Library
- FIXED: The type library object type-checking for the list, chars, and codes types to always throw instantiation errors whenever the term being checked is a partial list. Before, a type error would be throw if the term was a partial list but not a variable.
- ADDED: Library format that abstracts how the different backends make available the de facto standard format/2-3 predicates.
- ADDED: Library dif that abstracts how the different backends make available the dif/2 predicate when implemented.
- ADDED: Parametric object object_wrapper_hook/1 to the hook_objects library.
- ADDED: Partial support for XSB to the coroutining library.
- ADDED: Additional tests for the coroutining library.
- ADDED: Predicate copy_file/2 to the os library.
- IMPROVED: Performance of the arbitrary library tests.

Tools
- CHANGED: The diagrams tool dot graph language export now uses the generic Monospace font name and output SVG files using the dot command -Gfontnames=svg option to avoid issues with text overflowing boxes.
- CHANGED: The debugger tool loader file to also load the dump_trace object.
- CHANGED: The packs tool save/1 and restore/1-2 predicates to save and restore pinning status.
- CHANGED: The packs tool registries object predicate defined/3 to defined/4.
- CHANGED: The packs tool lint/1-2 predicates to fail when specification errors are detected.
- ADDED: Predicates text_output_contents/1-3 and binary_output_contents/1-2 to the lgtunit tool.
- ADDED: Support for defining, saving, and restoring a simple form of packs virtual environments.
- ADDED: Support for defining the packs tool directory used to store packs and registries using the logtalk_packs library alias (which can be defined e.g. in a settings file).
- ADDED: Predicates logtalk_packs/0-1, readme/1, delete/0, pin/0, unpin/0, uninstall/0, and reset/0 to the packs tool.
- IMPROVED: The packs tool to handle all dependency relations including range dependencies.
- IMPROVED: The packs tool to print a warning if the pack being installed or updated requires a different backend from the one running the tool.
- UPDATED: The packs::clean/0 predicate to not leave empty directories behind.
- FIXED: The packs tool packs::dependents/1-3 predicates to avoid duplicated results.
- FIXED: The packs tool registries::add/3 predicate to delete a registry prior to re-adding it when using the force(true) option to prevent a git cloning failure.
- FIXED: The packs tool registries::clean/0 predicate to delete all registry archives instead of only of those registries that are defined.
- FIXED: The packs tool logtalk_packs/1 predicate to return a path using the backend internal format instead of the operating-system format.
- FIXED: Workaround packs tool portability issue with Ciao Prolog due to this system lack of supported for standard multifile predicate semantics.
- FIXED: Adding a registry or installing a pack from a local archive using a URL with non-escaped spaces.
- FIXED: Bug in the packs tool registries::defined/4 predicate report on how a registry is installed which could return directory for registries defined via archives.
- FIXED: A packs tool typo in the identifier for the Trealla Prolog backend.
- FIXED: Missing tutor tool explanation for non-tail recursive non-terminal definitions.
- FIXED: The debugger tool dump_trace utility object to ensure that it's always compiled in non-debug mode.

Examples
- CHANGED: The books example to avoid test failures due to irrelevant float printing issues.
- UPDATED: The coinduction example tests to use explicit assertions.
- UPDATED: The errors example to illustrate the generalized linter checks.
- UPDATED: The figures example to use the new dif library instead of the coroutining library to allow running with some more backend Prolog systems.

Tests
- ADDED: Tests for the valid syntaxes of the Prolog standard dynamic/1, discontiguous/1, meta_predicate/1, multifile/1, and op/3 directives.
- ADDED: Tests for the Prolog standard discontiguous/1, ensure_loaded/1, include/1, initialization/1, multifile/1, and op/3 directives.
- ADDED: Tests for the Prolog standard compound term syntax.
- ADDED: Additional tests for the writeq/2 predicate for atoms that require quoting to be input back correctly.
- ADDED: Tests for the write_term/3 predicate for writing of compound terms with (,)/2 arguments.
- ADDED: Additional test for the ::/2 message-sending control construct.
- ADDED: Additional test for the use_module/2 Logtalk directive.
- ADDED: Tests for the Logtalk predicate_property/2 method to check for predicate declaration and definition term position properties.
- ADDED: Tests for the de facto standard format/2-3 predicates for using the back-quote character for specifying a table fill character in format strings.
- UPDATED: Tests for the de facto standard format/2-3 predicates to also check format strings specified using a list of character codes or a list of characters.
