CodeRabbit test #224
CodeRabbit test #224
Conversation
WalkthroughWalkthroughThe Haskell project has seen a refactoring that streamlines the REPL and evaluation components. Changes include alterations to import declarations, exception handling, and function implementations. The REPL now excludes a specific function from an import and changes its control flow for expression handling. The Evaluator module is simplified, and the Expander's function signature and implementation have been updated to use new evaluation strategies. Changes

The review comment is verified. The exclusion of

The references to

The import of Debug.Trace is a red flag for production code as it is often used for debugging purposes and should not be present in the final version.

@gelisam You are correct; the line in question does not contain a direct call to trace. The function expandEval is used in several places within src/Expander.hs, but none of the provided contexts show a direct call to trace. If you need further investigation into the expandEval function's definition or other usages, please let me know.

The commented-out error handling code should be addressed. It's important to handle errors properly rather than commenting them out.

The use of trace within the EvalDefnAction case is a potential performance issue and should not be present in production code. It's also a sign that proper logging is not being used.

The use of inEarlierPhase without checking the result can lead to unhandled errors if the macro implementation fails. Proper error handling should be implemented.

@coderabbitai what is the type of inEarlierPhase? Is it producing an error by returning an Either or by throwing an exception?
There was a problem hiding this comment.
@gelisam The function inEarlierPhase has the type signature Expand a -> Expand a, which does not directly indicate the use of Either for error handling. Additionally, there is a reference to inEarlierPhase in the context of a case expression within tests/Test.hs, which might suggest pattern matching on a result type like Either. However, without more context, it's not conclusive whether inEarlierPhase is using exceptions or an Either-like type for error handling.
Would you like me to look into the specific usage within tests/Test.hs to clarify how errors are handled in that instance?
