Logtalk 3.81.0, Logtalk for VSCode 0.23.0, and Docker image releases

[Paulo Moura]

Hi,

Logtalk 3.81.0 is now available for downloading at:

https://logtalk.org/

This release updates the delegation control construct to also preserve the original meta-call context; adds support for runtime constructed "(^^)/2" goals; adds support for using the "(<<)/2" and "catch/3" control constructs in a grammar rule body; fixes meta-arguments handling issues (thanks to Alex Kouznetsov for the bug reports); accounts for the renaming of the LVM backend to XVM; improves documentation; improves the performance of the "json" library when parsing large files (thanks to Yurii Rashkovskii for the bug report); fixes the "meta_compiler" library expansion of meta-arguments that call Prolog module predicates; changes the "lgtunit" object "test/3" private predicate to no longer being declared as a meta-predicate, simplifying writing of meta-predicate tests; adds support for conditional and triggered breakpoints to the "debugger" tool; improves the "debugger" tool support for log points; improves the "debugger" tool performance when checking for leashed ports; fixes a bug in the "lgtdoc" tool when generating reStructuredText files; adds a new programming example illustrating the semantics of calling an inherited meta-predicate using a message to "self" versus using a "super" call; includes additional tests for the "(^^)/2" control construct; adds a Docker file for building an image with Logtalk, a subset of the supported Prolog backends, Jupyter, JupyterLab, and the Logtalk kernel; and includes new and improved VSCode/VSCodium support.
