Green Year CLI 🌳

A command-line tool to fill your GitHub contribution graph with fake commits. Make every day look like a productive day!

Ever wanted to paint your GitHub contribution graph a solid green? Or maybe you're testing tools that interact with Git history? green-year is a simple CLI tool that allows you to generate a commit history for any given date range, with a randomized number of commits per day to make it look more authentic.

🤔 Why?

• Aesthetics: For developers who love seeing a fully green contribution graph.
• Testing: Create repositories with a dense commit history for testing Git-related tools or scripts.
• Privacy: If you work in a private repository, your contributions don't show up. This tool can help you maintain a green public profile without exposing proprietary work.

✨ Features

• Custom Date Ranges: Specify any start and end date.
• Randomized Commit Frequency: Creates a variable number of commits each day to look more natural.
• Configurable Intensity: You can control the minimum and maximum number of commits per day.
• Easy to Use: A simple, straightforward command-line interface.
• Safe: Operates in a specific directory, preventing accidental changes to other projects.

⚠️ Important Warning

This tool rewrites Git history. It is highly recommended to use it only on a new, empty repository created specifically for this purpose. Using it on an existing repository with important history can lead to data loss. The final step requires a force push, which is a destructive action. Use with caution!

📦 Installation

You can install green-year globally using npm, which will make the green-year command available in your terminal.

npm install -g green-year

(Note: You need to publish your package to npm for this to work. The package name green-year might already be taken.)

🚀 Usage

The basic command requires a start date and an end date in YYYY-MM-DD format.

Command

green-year <startDate> <endDate> [options]

Arguments

• <startDate>: The start date for generating commits (e.g., 2024-01-01).
• <endDate>: The end date for generating commits (e.g., 2024-12-31).

Options

• --repo, -r: Path to the local Git repository. (Default: current directory .)
• --min: The minimum number of commits per day. (Default: 1)
• --max: The maximum number of commits per day. (Default: 5)
• --help, -h: Display the help menu.
• --version, -v: Display the package version.

Examples

1. Fill the entire year of 2024 with default activity (1-5 commits/day):

# First, create and navigate to a new directory
mkdir my-green-year
cd my-green-year
git init

# Run the command
green-year 2024-01-01 2024-12-31

2. Create a more intense commit history for a specific quarter:

green-year 2025-01-01 2025-03-31 --min 5 --max 15

3. Create subtle activity, allowing for days with no commits:

green-year 2024-07-01 2024-09-30 --min 0 --max 2

After Running the Command

Once the script finishes, you need to push the history to your GitHub repository.

# 1. Add your GitHub repository as the remote origin
git remote add origin https://github.com/your-username/your-repo-name.git

# 2. Force push the new history to the main branch
git push -u origin main --force

🛠️ How It Works

The script iterates through each day in your specified date range. For each day, it:

1. Generates a random number of commits based on your --min and --max settings.
2. For each commit, it creates a unique message and content.
3. It then uses the GIT_AUTHOR_DATE and GIT_COMMITTER_DATE environment variables to set the commit's timestamp to the correct historical date.
4. Finally, it runs git commit with the backdated information.

💻 Development

Interested in contributing? Here’s how to get started.

1. Clone the repository:

   git clone https://github.com/clare-codex/green-year.git
   cd green-year

2. Install dependencies:

   npm install

3. Link the package for local testing: npm link creates a global symlink to your local project directory. This allows you to run the green-year command anywhere on your system and have it execute your local development code.

   npm link

4. Make your changes and test them! You can now open a new terminal window, navigate to a test repository, and run the green-year command with your changes.
