Logtalk overview
Logtalk is an Open-Source, object-oriented logic programming language that extends and leverages the Prolog language with a feature set suitable for programming in-the-large.
Logtalk supports modern code encapsulation and code reuse mechanisms without compromising the declarative programming features of Prolog. Logtalk is implemented in highly portable code and can use most modern and standards compliant Prolog implementations as a back-end compiler. The Logtalk distribution features portable libraries and portable assertions, documenting, diagraming, and unit testing tools, plus extensive code editing and publishing support. It also includes extensive documentation and a large number of programming examples.
What’s new in version 3.76.0
Updated on Apr 01 2024
Logtalk compiler and runtime
- Changed: The reflection API now also includes calls/2 object and category properties when the callers are auxiliary predicates. This change allows the dead_code_scanner tool to avoid false positives when reporting non called predicates.
- Added: Implemented the object and category updates/2 property alias/2 and non_terminal/1 predicate properties.
- Improved: The compiler report of errors and warnings clause context for multifile predicates.
- Improved: Print a warning only for the first successful call to the logtalk_linter_hook/7 hook predicate.
- Fixed: The compiler to detect and report attempts to declare category predicates or non-terminals as both multifile and dynamic.
- Fixed: The updates/2 object and category property would not be reported for updated predicates in user.
- Fixed: The compiler to not create object and category calls/2 properties for built-in database predicate calls updating predicates in user.
- Fixed: False positive missing predicate linter warnings in logtalk_make/1 calls for the check target when analyzing (^^)/1 and (::)/1 calls from objects playing the role of instances.
