4-31: Consider adding edge case tests.The current test cases cover basic positive and negative integer inputs. Consider adding tests for edge cases such as zero, large integers, or invalid inputs to ensure robustness.
test "if with zero" do assert GetIntIf.get(0) == 0 end test "if with large positive integer" do assert GetIntIf.get(1_000_000) == 1 end test "if with large negative integer" do assert GetIntIf.get(-1_000_000) == 0 endlib/charms/prelude.ex (1)
11-12: Functionconstant_of_same_typedoes not need to be public.The
constant_of_same_typefunction is only used internally withinlib/charms/prelude.ex, and there is no evidence of external usage. Therefore, making it public is unnecessary and potentially exposes internal functionality without justification. Consider making it private to maintain encapsulation.Analysis chain
Verify the necessity of making
constant_of_same_typepublic.The function
constant_of_same_typeis now public but hidden from documentation. Ensure this change is necessary and doesn't expose functionality that should remain internal.Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash # Description: Verify the necessity of making `constant_of_same_type` public by checking its usage across the codebase. # Test: Search for usage of `constant_of_same_type`. Expect: Justified external usage. rg --type elixir $'constant_of_same_type'Length of output: 251

574-579: LGTM: Handling nil clause body.The function correctly handles nil clause bodies by yielding no value, which is appropriate for the intended functionality.
582-596: LGTM: Handling non-nil clause body.The function effectively expands non-nil clause bodies and yields the last evaluated value, handling both operations and values appropriately.
Line range hint
573-766: Overall Review: Enhancements toCharms.Defm.Expander.The changes successfully move the expansion logic of
Charms.Defm.iftoKernel.if, aligning with standard Elixir practices. The introduction of helper functions and modular design enhances maintainability and clarity.
Line range hint
739-766: LGTM: Restructuredexpand_macroforKernel.if.The function has been effectively restructured to use blocks and SCF for handling conditional logic, enhancing flexibility and maintainability. The modular design and use of helper functions ensure consistent clause body handling.
Ensure that the changes align with the overall codebase and verify if any dependent code needs adjustments.
Verification successful
No direct impact found for
expand_macrochanges withKernel.if.The search did not reveal any additional usages of the
expand_macrofunction withKernel.ifbeyond its definition. This suggests that the changes are self-contained and do not directly impact other parts of the codebase. Ensure that any indirect usage or framework-specific integration aligns with these changes.Scripts executed
