Summary by CodeRabbit

• Bug Fixes

  • Improved summary output to correctly display "comment" or "comments" based on the number of comments per file.

• Tests

  • Updated tests to verify the correct use of singular and plural forms in summary outputs.

Walkthrough

Update the write_summary function to display the word "comment" or "comments" after the count, depending on whether the count is singular or plural. Adjust the corresponding test to verify that the correct singular or plural label appears in the output.

Changes

File(s)	Change Summary
src/main.rs	Update write_summary to append "comment"/"comments" label after each count; update test to check for correct label usage.

Estimated code review effort

Possibly related PRs

• Add summary to vk pr output #21: Adds a summarize_files function to generate summary data, related as both PRs touch summary features in src/main.rs.

Poem

One comment or many, the summary knows,
With singular or plural, the output now shows.
Tests keep it honest, no matter the count,
Labels are proper, precision paramount.

**/*.rs

📄 CodeRabbit Inference Engine (AGENTS.md)

**/*.rs: Run cargo fmt, cargo clippy -- -D warnings, and RUSTFLAGS="-D warnings" cargo test before committing.
Clippy warnings MUST be disallowed.
Fix any warnings emitted during tests in the code itself rather than silencing them.
Where a function is too long, extract meaningfully named helper functions adhering to separation of concerns and CQRS.
Where a function has too many parameters, group related parameters in meaningfully named structs.
Where a function is returning a large error consider using Arc to reduce the amount of data returned.
Write unit and behavioural tests for new functionality. Run both before and after making any change.
Document public APIs using Rustdoc comments (///) so documentation can be generated with cargo doc.
Prefer immutable data and avoid unnecessary mut bindings.
Handle errors with the Result type instead of panicking where feasible.
Avoid unsafe code unless absolutely necessary and document any usage clearly.

• Prefer mockall for mocks/stubs.

• Prefer .expect() over .unwrap()

• Ensure that any API or behavioural changes are reflected in the documentation in docs/

• Ensure that any completed roadmap steps are recorded in the appropriate roadmap in docs/

🔇 Additional comments (2)

src/main.rs (2)

609-610: LGTM! Proper pluralisation implemented correctly.

The logic correctly uses singular "comment" for count of 1 and plural "comments" for all other counts, which aligns with English grammar rules.

---

1112-1113: Test assertions updated correctly to match the new output format.

The test now properly validates both singular and plural forms in the summary output, ensuring the pluralisation logic works as expected.

  • I pushed a fix in commit <commit_id>, please review it.
  • Explain this complex logic.
  • 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 explain this code block.
  • @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:
