9-33: Approve deprecation with suggestion for additional documentationThe deprecation of
WithArgs,WithInput, andWithOutputfunctions is appropriate and aligns with the PR objectives. It's good practice to mark these as deprecated while providing an alternative (WithCommand).To further improve the developer experience:
- Consider adding a brief example of how to use
WithCommandas a replacement in each deprecated function's documentation.- If not already present, update the package documentation to highlight these changes and provide migration guidelines.
44-49: Approve new WithErrorHandler function with minor suggestionThe new
WithErrorHandlerfunction is well-implemented and aligns perfectly with the PR objectives. It follows the established pattern for Option functions and correctly sets the ErrorHandler field of the App struct.Suggestion for improvement:
Consider adding a brief comment explaining the purpose of the ErrorHandler, its expected behavior, and possibly a small usage example. This would enhance the documentation and make it easier for developers to understand how to use this new option.app_test.go (3)
27-30: LGTM: Custom error handler implementation.The addition of the custom error handler using
commandline.WithErrorHandlerdirectly implements the PR's objective of allowing users to change the default error handler. This is an effective way to capture and handle errors in the test scenario.Consider adding a brief comment explaining the purpose of returning
falsefrom the error handler, as it might not be immediately clear to all readers:commandline.WithErrorHandler(func(merr error) bool { err = merr + // Return false to prevent default error handling return false }),
34-34: LGTM: Error assertion added.The addition of
assert.Assert(t, err != nil)effectively verifies that an error was captured during the test execution, validating the custom error handling functionality.Consider enhancing the assertion to check for a specific error. This would provide more precise validation of the error handling:
-assert.Assert(t, err != nil) +assert.ErrorIs(t, err, errExample)This change would ensure that not only an error occurred, but it's the specific error we expect (
errExample), which is defined and used in thetestAppstruct.

1-74: Overall: Effective implementation of custom error handling in tests.The changes in this file successfully implement and test the new custom error handling functionality, aligning well with the PR objectives. The modifications are minimal, non-intrusive, and maintain the overall structure and readability of the test. They provide better coverage of error scenarios, enhancing the robustness of the test suite.
As the project evolves, consider creating a separate test file for error handling scenarios if they become more complex or numerous. This would help maintain the focus and readability of individual test files.

1-58: Overall assessment: Changes are well-implemented and align with PR objectivesThe modifications to
options.gosuccessfully introduce the ability to set a custom error handler while maintaining backwards compatibility through appropriate deprecation of older functions. The code quality is good, and the changes are consistent with the existing codebase structure.The suggestions provided for documentation improvements are minor and aimed at enhancing developer experience. Overall, these changes effectively support the PR's goal of allowing users to change the default error handler.

17-17: LGTM: Error variable addition enhances test capabilities.The introduction of the
errvariable allows for explicit error capturing, which aligns well with the PR's objective of improving error handling. This change enhances the test's ability to verify error scenarios.app.go (1)
17-17: LGTM!Adding the
ErrorHandlerfield to theAppstruct enhances error handling flexibility.
Will allow changing the default error handler.
