3.85.0 Nov 12, 2024 New Release Logtalk compiler and runtime:
CHANGED: The logtalk_load_context/2 built-in predicate to type-check the key argument.
CHANGED: Attempting to define an entity/predicate alias equal to the original entity/predicate is now a compilation error instead of simply a warning.
CHANGED: Reclassified the underscore_variables flag as a backend flag instead of a linter flag.
ADDED: New meta-flag, linter, to manage the values of all the linter flags as a group.
ADDED: New linter flag, encodings, to control source file text encoding warnings.
ADDED: New linter flag, general, for warnings that are not controlled by a specific flag.
IMPROVED: Print a linter warning on redundant entity qualification in predicate directives.
IMPROVED: Detect and report as compilation errors use_module/1-2 and uses/1-2 directives when compiling a protocol.
IMPROVED: Report as compilation errors instead of compilation warnings use_module/1-2 directives when not compiling a module as an object while using a backend that doesn’t support modules.
IMPROVED: Report as compilation errors export/1 and reexport/2 directives when not compiling a module as an object.
FIXED: The compiler to prevent trying to compile a Prolog use_module/1 directive as a Logtalk directive when compiling a module as an object.
FIXED: Detection of a file trying to recursively load itself to not throw a permission error when reloading a file that previously failed to load.
FIXED: Misleading error when compiling dynamic/1, discontiguous/1, and multifile/1 directives with arguments with redundant entity qualification.
Prolog adapter and integration files
UPDATED: Trealla Prolog adapter file to require version 2.59.21 or later.
Documentation:
IMPROVED: Documentation of the issue_creator tool.
IMPROVED: The Handbook documentation on performance, adding a section on circular references.
IMPROVED: The Handbook documentation on the logtalk_make/0-1 built-in predicates.
UPDATED: The Handbook documentation on the underscore_variables flag.
Lib
9.2.8.1 Oct 24, 2024 New Release BUILD: Make sure to clear DISPLAY when running xpce steps While the build works without a DISPLAY variable, an invalid variable causes the build to fail.
TEST: Disable collation_key/2 test for MacOS Macos Sequoia (15) wcsxfrm() returns garbage.
3.84.0 Oct 22, 2024 New Release Logtalk compiler and runtime:
ADDED: New fails_if key to the info/2 predicate directive for documenting predicate fail conditions. Adopted from ECLiPSe similar fail_if key.
IMPROVED: Detect and report when a uses/2 directive references the object that contains it.
IMPROVED: Detect and report when a use_module/2 directive references the module (being compiled as an object) that contains it.
IMPROVED: Detect and report when an alias/2 directive references the entity that contains it.
IMPROVED: Detect and report when a source file attempts to load itself.
IMPROVED: Error reporting when a source file attempts to include itself.
FIXED: Prevent using grammar rules to try to redefine the (;)/2, (->)/2, and (*->)/2 control constructs.
Documentation:
IMPROVED: Handbook glossary entries for “predicate”, “method”, “sender”, and “this”.
IMPROVED: Handbook section on running parallel Logtalk processes.
IMPROVED: Documentation of the packs tool on working with packs using git archive URLs, signing packs, and encrypting packs.
Library:
CHANGED: The library object hook_pipeline/1 to not use default expansions and pass as-is any terms and goals not expanded by a hook object to the next hook object. This library object now calls the expanding protocol predicates directly instead of using the expand_term/2 and expand_goal/2 built-in methods.
CHANGED: The library object hook_set/1 to call the expanding protocol predicates directly instead of using the expand_term/2 and expand_goal/2 built-in methods.
ADDED: Predicates delete_directory_and_contents/1 and delete_directory_contents/1 to the os library.
ADDED: Additional tests for the dictionaries library.
IMPROVED: Documentation of the dictionaries library predicates.
FIXED: The library object type to properly load the SWI-Prolog unicode module library when running with this backend. Thanks to Alex Kouznetsov for the bug report.
FIXED: The definition of the os::delete_file/1 library predicate for YAP.
FIXED: Bug in t
