Walkthrough

The changes update the application's styling, structure, and functionality. The CSS now provides comprehensive theming, layout, and interactive element styles including dark mode and modal dialogs. The HTML has been reorganized to reference external CSS and JS files while improving readability. The JavaScript introduces a global state management system for a JSON tool with functions to persist UI state, manage tabs for formatting, comparison, and code generation, and handle various utility interactions.

Poem

I'm a bunny dancing in lines of code,
Hopping through CSS fields so bold.
HTML rows reformed with a stylish tweak,
And JS remembers every click we seek.
With whiskers twitching, I cheer this delightful mode! 🐰✨

🪧 Tips

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.
