Walkthrough

The changes involve modifications to a regular expression in the tryWrapHtmlCode function located in app/components/markdown.tsx. The adjustments specifically refine how newline characters and quote marks are handled in HTML structures, enhancing the function's ability to process optional whitespace and newline characters before closing HTML tags.

Poem

In the land of code where rabbits play,
A regex dance brightens the day.
Newlines and quotes, all in a row,
Tamed by the changes that help them flow.
With a hop and a skip, we refine our art,
Making HTML sing from the very start! 🐇✨

255-255: Approved: Regex modification improves quoteEnd extraction

The change in the regex pattern addresses the issue mentioned in the PR objectives. By modifying the newline and backtick capturing groups from lazy (*?) to greedy (*), it ensures that all relevant characters are captured. This should resolve the problem of incorrect splitting of code blocks.

Specifically:

1. ([\n\r]*?) → ([\n\r]*): Captures all newlines after </html> tag.
2. ([]*?)→([]*): Captures all backticks in the quoteEnd group.

These modifications align well with the goal of fixing the quoteEnd extraction regex.

255-255: Verify the impact on edge cases

While the regex change addresses the reported issue, it's crucial to ensure it doesn't introduce unintended side effects. Please consider the following:

1. Test with various HTML content, including cases with multiple newlines and backticks after the closing </html> tag.
2. Verify that the function still correctly handles cases where the HTML content is already wrapped in code fence markers.
3. Check if this change affects the handling of nested HTML code blocks, if applicable.

To assist with verification, you can use the following script to test various scenarios:

\n/')

if [ "$result" == "$expected" ]; then
    echo "PASS"
else
    echo "FAIL"
    echo "Input: $input"
    echo "Expected: $expected"
    echo "Got: $result"
fi

}

Test cases

test_wrap_html "" "\n\n" test_wrap_html "</body></html>\n" "</body></html>\n\n"
test_wrap_html "\n\n" "\n\n" test_wrap_html "</body></html>``" "</body></html>``" test_wrap_html "</body></html>" "" test_wrap_html "</body></html>\n" "\n```"

This script simulates the behavior of the `tryWrapHtmlCode` function for the closing part of HTML content. Run it and ensure all test cases pass as expected.

### Chat

There are 3 ways to chat with [CodeRabbit](https://coderabbit.ai):

- 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.

- `@coderabbitai summary` to regenerate the summary of the PR.
- `@coderabbitai resolve` resolve all the CodeRabbit review comments.
- `@coderabbitai configuration` to show the current CodeRabbit configuration for the repository.
- `@coderabbitai help` to get help.

### Other keywords and placeholders

- Add `@coderabbitai ignore` anywhere in the PR description to prevent this PR from being reviewed.
- Add `@coderabbitai summary` to generate the high-level summary at a specific location in the PR description.
