Walkthrough

The changes in this pull request involve a modification of the Truncate component and its associated utilities. The parameter for the truncation length has been updated from length to idealLength, indicating a shift in how truncation is defined. Additionally, test cases have been adjusted to reflect this new parameter and its expected behavior. The overall logic of the truncation process remains intact, but the implementation and testing have been refined for clarity and accuracy.

12-36: LGTM: Improved truncation logic

The new implementation of the truncate function aligns well with its description and the PR objectives. It correctly handles different scenarios, such as when the idealLength ends on a space or in the middle of a word, ensuring that words are not split apart during truncation.

The removal of the omission logic simplifies the function and makes it more focused on its primary task. The overall logic is clear and concise.

Consider renaming the nextSpace variable to nextSpaceIndex for better clarity:

-	const nextSpace = string.slice(idealLength).search(" ");
+	const nextSpaceIndex = string.slice(idealLength).search(" ");
 	return {
-		string: string.slice(0, idealLength + nextSpace),
+		string: string.slice(0, idealLength + nextSpaceIndex),
 		isTruncated: true,
 	};

packages/ui-truncate/src/components/Truncate/__tests__/utilities.test.ts (2)

13-19: Consider differentiating this test case from the previous one.

This test case has the same expected output as the previous one, despite having a different idealLength. To make the test suite more robust and clear:

1. Consider modifying the input string or expected output to better demonstrate the "truncate at the next space found right after the ideal length" behavior.
2. Update the test case name to more accurately reflect the specific scenario being tested.

Here's a suggested modification:

it("should truncate at the next space after the ideal length", () => {
  const result = truncate({
    string: "Hello there, World!",
    idealLength: 7,
  });
  expect(result).toEqual({ string: "Hello there,", isTruncated: true });
});

This change would better illustrate the difference between truncating at the ideal length and truncating at the next space after the ideal length.

---

21-27: Approve implementation, but suggest renaming the test case.

The test case correctly demonstrates the truncation behavior with the new idealLength parameter. However, to improve clarity and differentiate it from the previous test case:

Consider renaming this test case to better reflect its specific scenario. For example:

it("should truncate a longer string at the next space after the ideal length", () => {
  // ... (rest of the test case remains the same)
});

This name more accurately describes what this particular test case is verifying.

20-20: Approve the parameter name change and suggest utility function verification.

The change from length to idealLength: length aligns well with the PR objective of not splitting words apart during truncation. This semantic shift suggests a more flexible approach to determining the truncation point, which should lead to improved readability of the truncated text.

To ensure full compatibility, please verify that the truncate utility function in ./utilities.ts has been updated to handle this idealLength parameter correctly. Run the following script to check the implementation:

If the script doesn't return any results, it might indicate that the truncate function hasn't been updated to match this new parameter name. In that case, please update the utility function accordingly.

5-5: LGTM: Improved type definition

The change from length to idealLength in the TruncateOptions type better reflects the function's behavior. Removing the omission property simplifies the API, which is a good improvement. Making idealLength optional allows for using a default value, providing flexibility to the users of this function.

---

12-36: Great job addressing the PR objective

The changes in the truncate function directly address the PR objective of ensuring that words are not split apart during truncation. The new implementation looks for the next space after the ideal length if truncation is necessary, which guarantees that whole words are preserved. This is a significant improvement that enhances the usability and readability of the truncated text.

packages/ui-truncate/src/components/Truncate/__tests__/utilities.test.ts (3)

5-11: LGTM: Test case correctly uses the new idealLength parameter.

The test case has been updated to use idealLength instead of length, which aligns with the changes made to the truncate function. The expected result is appropriate for the given input and ideal length.

---

29-35: LGTM: Edge case correctly handled.

This test case effectively verifies the behavior when the idealLength is greater than the string length. It correctly expects the original string to be returned unchanged with isTruncated set to false.

---

1-36: Overall, the test cases have been successfully updated to reflect the new truncation behavior.

The changes in this file align well with the PR objectives. All test cases now use idealLength instead of length, and they cover various scenarios including truncation at ideal length, truncation at the next space, and handling of edge cases where the ideal length exceeds the string length.

To further improve the test suite:

1. Consider implementing the suggested changes to differentiate the second and third test cases more clearly.
2. Ensure that the test cases cover all possible edge cases and scenarios for the updated truncation logic.

To ensure comprehensive test coverage, let's verify if there are any other test files for the truncate function:

This will help us confirm if we've reviewed all relevant test files for the truncate function.

packages/ui-truncate/src/components/Truncate/__tests__/Truncate.test.tsx (1)

21-21: Approved change, but clarification needed on truncation behavior

The updated test expectation aligns with the PR objective of not splitting words apart during truncation. This is a positive change that should improve the user experience.

However, I have a few points that need clarification:

1. The test still uses the length prop with a value of 20, but the AI summary mentioned a change from length to idealLength. Can you confirm if this prop name change has been implemented in the component?

2. The expected truncated text is now longer than the specified length of 20. Could you explain how the new truncation logic works? Is it now aiming for the nearest word boundary after the specified length?

3. Has the component's behavior changed, or was this test updated to match the existing behavior?

To help clarify these points, could you run the following script to check the implementation of the Truncate component?
