This allows functions-to-synthesize to appear in grammars.
To do this, we rely on (higher-order) equalities in sygus verification calls.
Note this requires changing the error handling of free variables in grammars, since we do not have access to the set of functions-to-synthesize at the API level.
Previously, we were using io.github.cvc5.api to mirror the C++
namespace that the API was in. The namespace of the C++ API changed to
simply cvc5 and so this commit updates the Java package accordingly.
This PR patches cross reference links in Kind.java comments for now until a proper way is implemented that handles documentation for cpp, python and Java API.
This commit ensures we don't segfault in the SyGuS API (for non-text inputs) if the option sygus is not set to true. It also renames mkSygusVar to declareSygusVar for consistency with the sygus input format.
For SyGuS API inputs, we now use the option sygus to true instead of setting the language to sygus2.
This furthermore changes a few details in set-defaults regarding the relationship between the language, the sygus option, and when to apply default options for sygus.
It also adds a unit test for checkSynth.
This PR enables CI for java tests by adding --java-bindings to ci.yml.
It also replaces the unreliable finalize method and instead uses AutoCloseable and explicit close method to clean up dynamic memory allocated by java native interface.
The PR fixes compile errors for SolverTest.java and runtime errors for Solver.defineFun.
