| Logtalk 9.2.9.1 Nov 19, 2025 |
ADDED: Using the option --home=dir, set SWI_HOME_DIR. This ensures that sub processes can access Prolog's home and, when calling Prolog, execute the same Prolog system. TEST: Base saved-state tests on new prolog(Tool) option of process_create/3. FIXED: Allow swipl -o exe -c input.pl to pass --home=dir option. |
| Logtalk 3.96.0 Nov 18, 2025 |
Logtalk compiler and runtime: ADDED: Predicates logtalk::loaded_files_topological_sort/1-2 for sorting loaded files by their dependencies. IMPROVED: The implementation of the logtalk_make/0-1 predicates for the target all to avoid or minimize compilation warnings due to out-of-order loading of modified source files. See the make tool documentation for details. FIXED: Printing of the default flag values at startup to list the prolog_dialect flag as a read-only flag. FIXED: The linter warning for the use of Logtalk or Prolog top-level shortcuts as directives ignored the portability flag. Prolog adapter and integration files: CHANGED: Trealla Prolog adapter file to require version 2.84.29 or later. UPDATED: ECLiPSe adapter file to use the new read_term/3 predicate line/1 option introduced in version 7.2#5 for accurate read term starting lines. FIXED: CxProlog adapter file to workaround its implementation of the predicate_property/2 built-in predicate returning properties for unknown predicates. FIXED: Quintus Prolog adapter file to avoid some spurious suspicious call warnings when loading tools such as lgtunit. FIXED: Quintus Prolog adapter file missing expansions for some arithmetic functions. Documentation: ADDED: A “Known issues” section to the documentation of the make tool. UPDATED: The Handbook on finding an optimal file loading order using the new logtalk::loaded_files_topological_sort/1-2 predicates. Library: IMPROVED: The os::time_stamp/1 predicate implementation for SICStus Prolog, Trealla Prolog, XSB, and YAP. IMPROVED: Tests for the os library predicates. UPDATED: The format library linter checker to be aware of the ~W control sequence that uses two arguments. Tools: IMPROVED: The logtalk_doclet.sh script now kills all created child processes on exit. FIXED: Syntax error when loading the diagrams tool using the GNU Prolog backend. FIXED: The logtalk_doclet.sh and logtalk_tester.sh scripts to also check for the gnutimeout alternative name for the GNU cor |
| Logtalk 3.95.0 Oct 30, 2025 |
Logtalk compiler and runtime: ADDED: Predicate directive mode_non_terminal/2 to distinguish non-terminal mode declarations from predicate mode declarations. UPDATED: The logtalk built-in object to use the new mode_non_terminal/2 directive. Prolog adapter and integration files: UPDATED: The XSB adapter file with an implementation of the predicate that converts between internal and native file system paths. Documentation: UPDATED: Simplified page titles in the HTML versions of the Handbook and APIs documentation. Library: UPDATED: The grammars library to use the new mode_non_terminal/2 directive. Tools: CHANGED: The diagrams tool predicate_url_target_format/1 option to only accept sphinx and other values. IMPROVED: The diagrams tool generated diagram node links by encompassing just the relevant text. IMPROVED: The lgtunit tool lint checking of test assertions. UPDATED: The tutor tool to explain the new lgtunit tool linter warnings. UPDATED: The lgtunit tool to allow using failed_test_reason//1 as a public non-terminal to better support IDEs such as VSCode. UPDATED: The code_metrics, help, lgtdoc, and tutor tools for the new mode_non_terminal/2 directive. UPDATED: The dead_code_scanner tool for additional tests using use_module/2 directives. UPDATED: The diagrams tool to also load the Mermaid experimental support. FIXED: A lgtdoc tool bug when reporting missing predicate directives for declared non-terminals. FIXED: A lgtdoc tool bug when reporting missing predicate directives when the scope directive is found in an included file. FIXED: The lgtdoc tool logtalk.css file to avoid rendering issues when viewing documentation in VSCode. FIXED: The lgtdoc tool XSLT files for converting XML documentation files to (X)HTML files to correctly handle italic, bold, and monospaced text fragments. FIXED: The diagrams tool to exclude the default scratch directory on Windows (lgt_tmp) when generating diagrams for all sub-directories or sub-libraries. FIXED: The diagrams tool generate |
