Git Repository Setup with Submodules

This project demonstrates how to automate the setup of a Git repository with submodules using a configuration file. This is useful when you want to initialize a repository and manage its dependencies through submodules programmatically.

Prerequisites

• Python 3.x
• git command-line tool installed on your system
• GitPython library. You can install it via pip:

  pip install gitpython

Configuration

The repository configuration is specified in a JSON file named repos_config.json. Here is an example configuration:

{
    "parent_dir": "uses_db",
    "submodules": [
        {
            "url": "git@github.com:dudezilla/make_db.git",
            "path": "make_db"
        }
    ]
}

• parent_dir: Specifies the name of the directory to be created and initialized as a Git repository.
• submodules: List of submodules to be added to the repository. Each submodule requires:
  • url: Repository URL of the submodule.
  • path: File path relative to the parent_dir where the submodule will be located.

Usage Instructions

1. Clone the Main Repository

Use this snippet to create an initial repository setup:

...  git clone git@github.com:dudezilla/modular_git_template.git
     python -m venv venv
     (activate venv) venv/scripts/activate on Windows or source ./venv/bin/activate
     cd ./modular_git_template
     pip install -r requirements.txt
     python template.py

-**on Debian based systems python3 is used to start Python rather than python.

Script Functions

• load_config(file_path): Loads the configuration from a JSON file.
• initialize_repo(parent_dir): Creates a directory if it doesn't exist, initializes it as a Git repository.
• add_submodule(repo, submodule_url, submodule_path): Adds a submodule to the repository.
• setup_git_repo_with_dependencies(config_file): Loads the configuration, initializes the main repo, adds submodules, creates a README, stages changes, and commits to the repository.

Output

Once completed, the script will:

• Create a main repository directory.
• Add defined submodules.
• Generate a README.md file listing all the submodules.
• Commit all changes with an initial commit message.

You'll see the following message upon successful completion:

Repository setup complete. You can clone it using:
git clone --recurse-submodules git@github.com:dudezilla/<>
