Walkthrough

This update introduces Elixir starter templates, solution files, and supporting infrastructure for a "Build Your Own Git" challenge. It adds shell scripts for compiling and running Elixir projects, project configuration files, code formatters, and documentation. The main program logic is implemented in a new CLI module with a main/1 function that handles command-line arguments to initialize a minimal Git repository structure. The update also includes Dockerfile and YAML configuration for environment setup, as well as solution files demonstrating the completed logic for the challenge's first stage.

Poem

In Elixir fields where code does sprout,
New scripts and docs are hopping out!
With .git and mix, the groundwork’s laid,
For Git-like tools by bunnies made.
Hop, compile, and run with glee—
The repo’s fresh as it can be!

🪧 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.
