x/logic/prolog/assert.go (1)
209-220: LGTM with a minor suggestion.The
AssertStreamfunction is well-implemented and consistent with other assertion functions in this file. It correctly handles different cases and follows the established error handling patterns.To improve consistency with other functions in this file, consider using a named return value for the error. This would make the function signature more aligned with functions like
AssertAtomandAssertCharacterCode.Here's a suggested modification to the function signature:
func AssertStream(stream engine.Term, env *engine.Env) (st *engine.Stream, err error) { // ... rest of the function remains the same }🧰 Tools

[warning] 211-218: x/logic/prolog/assert.go#L211-L218
Added lines #L211 - L218 were not covered by testsx/logic/interpreter/registry.go (1)
121-125: LGTM! New predicates align with PR objectives.The newly added predicates (
term_to_atom/2,atomic_list_concat/2,atomic_list_concat/3,json_read/2, andjson_write/2) align well with the PR objectives, enhancing the system's capabilities for JSON handling and string manipulation.Consider updating the package documentation to include information about these new predicates, their usage, and any potential caveats (e.g., encoding issues mentioned in the PR objectives for
atomic_list_concat).x/logic/predicate/atom_test.go (4)
26-87: Comprehensive test cases forterm_to_atom.The test cases cover a good range of scenarios:
- Error cases: instantiation errors and type errors.
- Various input types: atoms, integers, floats, strings.
- Edge cases: empty strings, negative numbers, scientific notation.
Consider adding a few more test cases:
- A very large integer or float to test potential overflow scenarios.
- A unicode string to ensure proper handling of non-ASCII characters.
- A compound term to verify how complex structures are handled.
90-140: Robust test execution and result validation.The test execution and result validation are well-implemented:
- Each test case is run in isolation with a fresh context and interpreter.
- Error cases are properly checked and compared.
- Successful cases validate both the presence and content of the results.
One minor suggestion:
Consider extracting the result validation logic (lines 109-133) into a separate helper function to improve readability and reduce duplication, as this pattern is likely to be repeated in other test functions.
146-215: Comprehensive test cases foratomic_list_concat.The test cases cover a good range of scenarios:
- Error cases: instantiation errors and type errors.
- Edge cases: empty lists, single-element lists.
- Various input types: atoms, numbers, strings.
- Different separators for the 3-argument version.
Consider adding a few more test cases:
- A case with a very long list to test potential performance issues.
- A case with unicode characters in the list elements and separator.
- A case where the separator is a multi-character string.
218-270: Consistent test execution and result validation.The test execution and result validation are implemented consistently with
TestTermToAtom:
- Each test case runs in isolation with a fresh context and interpreter.
- Both
atomic_list_concat/2andatomic_list_concat/3are registered with the interpreter.- Error cases and successful cases are properly validated.
As mentioned earlier, consider extracting the result validation logic (lines 238-262) into a separate helper function to improve readability and reduce duplication across test functions.
x/logic/predicate/atom.go (1)
81-113: Add unit tests forAtomicListConcat3to cover edge casesIt's important to ensure that
AtomicListConcat3correctly handles various edge cases, such as empty lists, singleton lists, lists with non-atomic elements, and lists containing different types like integers and strings. Consider adding unit tests to cover these scenarios.Would you like assistance in generating unit tests for these cases?

725-782: Add test cases for successful execution ofJSONReadCurrently,
TestJSONReadincludes only test cases that expect errors. Consider adding test cases that verify successful reading from valid text input streams to ensure correct functionality.
784-844: Add test cases for successful execution ofJSONWriteSimilarly,
TestJSONWritefocuses on error scenarios. Adding test cases that confirm successful writing to valid text output streams would enhance test coverage and validate proper behavior.

41-43: Improved stream handling and validationThe use of
prolog.AssertStreamis a good improvement. It simplifies error handling and stream validation, making the code more robust and easier to maintain.
54-54: Consistent variable usageThe change from
stoisfor reading runes is consistent with the new stream handling introduced earlier. This improves code consistency and readability.

1-180: Overall assessment: Improved code quality and consistencyThe changes in this file, particularly in the
ReadStringfunction, enhance error handling and maintain code consistency. The use ofprolog.AssertStreamfor stream validation is a notable improvement. These modifications align well with the PR objectives of enhancing the expression of governance rules within the codebase.x/logic/interpreter/registry.go (2)
70-71: Ensure comprehensive testing and documentation updates.The changes to existing predicates and the addition of new ones significantly enhance the system's capabilities. To maintain the robustness and usability of the system:
- Ensure that comprehensive tests are in place for both the modified and new predicates.
- Update any API documentation or user guides to reflect these changes.
- Review and update any code examples or tutorials that might be affected by these changes.
To verify the test coverage for the new and modified predicates, you can run the following script:
#!/bin/bash # Description: Check for test coverage of new and modified predicates # Test: Search for test functions related to the new and modified predicates rg --type go -e 'func Test.*(?:ReadTerm3?|WriteTerm3?|TermToAtom|AtomicListConcat|JSONRead|JSONWrite)' --glob 'x/logic/**/*_test.go'Also applies to: 121-125

x/logic/predicate/atom_test.go (3)
24-142: Well-structured and comprehensive test function forterm_to_atom.The
TestTermToAtomfunction is well-organized and follows good testing practices:
- It uses a table-driven test approach, which allows for easy addition of new test cases.
- The test cases cover a wide range of scenarios, including error cases and edge cases.
- The use of GoConvey provides a clear and readable structure for the tests.
- The test setup with an in-memory database and light interpreter ensures good isolation for each test case.
144-271: Well-structured test function foratomic_list_concat.The
TestAtomicListConcatfunction follows the same good practices asTestTermToAtom:
- It uses a table-driven test approach for easy expansion.
- The test cases cover both
atomic_list_concat/2andatomic_list_concat/3variants.- The use of GoConvey and the test setup are consistent with the previous function, maintaining a good testing pattern throughout the file.
1-271: Overall, excellent test coverage with minor suggestions for improvement.This test file demonstrates high-quality unit testing for the
term_to_atomandatomic_list_concatpredicates. The use of table-driven tests, GoConvey framework, and consistent test patterns across functions contributes to maintainable and extensible tests.Suggestions for further improvement:
- Refactor the common result validation logic into a shared helper function to reduce duplication.
- Add a few more edge cases as suggested in the individual function reviews.
- Consider adding benchmarks for these predicates, especially for
atomic_list_concatwith large inputs, to ensure performance characteristics.x/logic/predicate/term.go (1)

Purpose
This PR mainly introduces some useful predicates for expressing governance rules.
json_read/2,json_write/3Following PR #782, we can now introduce JSON readers and writers in stream mode.
Example:
atomic_list_concat/2&atomic_list_concat/3These predicates can be used for various concatenation needs, such as constructing URIs (with caution around encoding issues).
