We recommend that you space out your commits to avoid hitting the rate limit.

🚦 How do rate limits work?

CodeRabbit enforces hourly rate limits for each developer per organization.

Our paid plans have higher rate limits than the trial, open-source and free plans. In all cases, we re-allow further reviews after a brief timeout.

📝 Walkthrough

Walkthrough

This pull request involves modifications to three files: .credo.exs, lib/recode/task/locals_without_parens.ex, and test/recode/task/locals_without_parens_test.exs.

In .credo.exs, the configuration has been updated to enable stricter linting by changing the strict setting to true. Additionally, two specific Credo checks, Credo.Check.Readability.ParenthesesOnZeroArityDefs and Credo.Check.Refactor.FunctionArity, have been moved to the disabled list.

The lib/recode/task/locals_without_parens.ex file sees significant changes to the remove_parens function, enhancing its logic for handling parentheses in local function calls. The implementation now includes additional clauses for various node structures and a refined approach to modifying nodes when autocorrect is enabled.

Correspondingly, the test file test/recode/task/locals_without_parens_test.exs has been expanded with new test cases to validate the updated functionality, focusing on scenarios involving function definitions, do: clauses, and preserving parentheses in specific contexts.

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>, please review it.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @coderabbitai read src/utils.ts and generate unit testing code.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

122-123: Consider a more robust method to detect parentheses

Relying on Keyword.has_key?(meta, :closing) assumes that the presence of the :closing key accurately indicates parentheses. Changes in the parser or formatter could affect this metadata. Consider using a more reliable approach to determine if parentheses are present, such as analyzing the syntactical structure directly.

163-164: Review the decision to disable specific Credo checks

Disabling {Credo.Check.Readability.ParenthesesOnZeroArityDefs, []} and {Credo.Check.Refactor.FunctionArity, []} means these checks will not run. Consider whether these checks are unnecessary for your codebase or if they could provide valuable insights into potential improvements.

lib/recode/task/locals_without_parens.ex (2)

26-27: Good use of module attributes for clarity

Defining @def and @exclude as module attributes enhances code readability and maintainability by clearly specifying the lists of forms to be used in pattern matching.


70-71: Verify the use of Zipper.next(zipper) to avoid skipping nodes

In the clause handling function definitions, using Zipper.next(zipper) advances the zipper, potentially skipping nodes that may need processing. Ensure this is intentional and that no necessary nodes are being overlooked.

test/recode/task/locals_without_parens_test.exs (4)

34-61: Excellent addition of test cases for function definitions

The new test "does not remove parens in def*" effectively ensures that parentheses are not removed from function definitions, covering def, defp, defmacro, and defmacrop. This enhances the reliability of the LocalsWithoutParens task.


Line range hint 83-92: Corrected test name enhances clarity

Renaming the test from "adds no issue for dev" to "adds no issue for def" accurately reflects the purpose of the test, improving code readability and understanding.


93-101: Added tests ensure correct handling of do: syntax

The test "add no issue for parens in do:" confirms that parentheses are appropriately handled when using the do: syntax in function definitions. This addition strengthens test coverage for this specific case.


103-113: Tests for tuples and maps improve robustness

The test "add no issue for parens in tuples and maps" verifies that parentheses in tuples and maps are handled correctly, ensuring that no unnecessary issues are reported. This contributes to more comprehensive test coverage.

.credo.exs (1)

49-49: Enabling strict: true increases code scrutiny

Setting strict: true will enforce stricter linting rules and may result in more warnings and errors. Ensure that the team is prepared to address these additional reports and that this aligns with the project's code quality goals.

Line range hint 114-118: Document the version-based dependency exclusion.

The implementation of the version check is correct. However, please add a comment explaining why freedom_formatter is excluded for Elixir 1.18+. This will help future maintainers understand the rationale behind this version-specific dependency management.

+      # freedom_formatter is not needed for Elixir 1.18+ because ...
