Walkthrough

The changes update the course definition by modifying the description_md in the YAML file. The new wording specifies that participants will build their own implementation of grep without using built-in regex features. Additionally, two new notes are added in the stages "Match a literal character" and "Match digits," clarifying that participants must implement a regex matcher from scratch, thereby reinforcing the constraints and expectations for the challenge.

Changes

File	Change Summary
course-definition.yml	Modified description_md to clarify that participants must implement grep without built-in regex features. Added notes in "Match a literal character" and "Match digits" stages to emphasize this requirement.

Poem

I’m a rabbit hopping on the code trail,
New notes springing in with a rhythmic tale.
Built-in regex, you must not prevail—
Write it from scratch, let your logic sail.
In this grep challenge, may your code never fail! 🐇✨

🪧 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.
