Logtalk compiler and runtime
- CHANGED: Also print a silent compiling_file/2 message when processing include/1 directives that can be intercepted by tools.
- CHANGED: Renamed the logtalk object debug_handler_provider/1 predicate to debug_handler/1 and the debug_handler/2 predicate to debug_handler/3.
- ADDED: New activate_debug_handler/1, deactivate_debug_handler/0, and active_debug_handler/1 predicates to the logtalk object supporting the activation and deactivation of debug handler providers.
- ADDED: New entity property, directive/2, providing the entity opening directive start and end lines when defined in a source file.
- ADDED: Compiler support for using backend proprietary directives in calls to the create_object/4 and create_category/4 built-in predicates.
- IMPROVED: Allow multiple debug handler providers to be loaded simultaneously (with the restriction that only one of them can be active at any given time).
- FIXED: Regression preventing linter warnings for duplicated clauses and grammar rules.
- FIXED: Reporting of the number of compilation warnings will fail to count some of the warnings.
- FIXED: The phrase/2-3 built-in methods to properly handle a runtime bound first argument when called from a meta-predicate. Thanks to Alex Kouznetsov for the bug report.
Prolog adapter and integration files
- UPDATED: The LVM adapter file to support encryption of the intermediate Prolog files generated by the compiler by setting the prolog_compiler flag to [encrypt(true)] and the clean flag to off.
- ADDED: SWI-Prolog adapter file initial support for using tabling directives and predicates in dynamically created objects.
Documentation
- ADDED: A "Known issues" section to the embedding scripts documentation.
- ADDED: Handbook documentation on how to define debug handler providers.
- ADDED: Handbook documentation on debugging using log points.
Library
- ADDED: New sequential_occurrences/2-3 list predicates to the types library.
Tools
- CHANGED: The debugger and ports_profiler tools for the new debug handler predicates.
- ADDED: New start/0 and stop/0 predicates to the ports_profiler object to simplify activating and deactivating it as the debug handler provider.
- ADDED: Support for log points to the debugger tool.
- ADDED: New public explain//1 non-terminal to the tutor tool.
- UPDATED: The debugger object debug/0 and trace/0 predicates to activate the object as the current debug handler provider. Updated also the nodebug/0 predicate to deactivate the debugger object as the current debug handler provider.
- UPDATED: The debugger tool to print silent port messages (when leashed) that can be intercepted by tools.
- IMPROVED: The packs tool to clarify when trying to install a pack that's already installed if it's installed from a different registry.
Examples
- FIXED: The missing_data example loader file.
- FIXED: Lambda expression warnings when loading the missing_data example.
IDEs, text editors, and syntax highlighters support
- ADDED: VSCode support for managing spy points and log points.
- ADDED: VSCode handling of compiling_file/2 messages to support clearing file diagnostics when recompiling files.
- UPDATED: VSCode support to allow the find_implementations/4 predicate to also find protocol implementations.
- FIXED: VSCode cases where non-terminal declarations and definitions would not be found.
- FIXED: VSCode case where the definition for a predicate listed in a uses/2 directive would not be found.
- FIXED: VSCode finding of entity references to avoid false positives.
- FIXED: VSCode support when (re-)running tests without using the GUI command.
- FIXED: VSCode support for clearing file diagnostics when recompiling files.
