Automate Git Submodule Addition with Bash Script

A Bash script that automates adding Git submodules to a repository. It handles branch creation, submodule addition, commit, push, and pull request creation via the GitHub CLI.

Features

• Adds a Git submodule to a specified directory within your repository.
• Automatically creates a new branch named after the submodule repository.
• Commits and pushes changes to GitHub.
• Creates a pull request using the GitHub CLI (gh).

Tech Stack

• Shell scripting (Bash)
• Git
• GitHub CLI (gh)

Getting Started

Prerequisites

• Git installed and configured on your system.
• GitHub CLI (gh) installed and authenticated. Installation instructions: GitHub CLI Installation.

Installation & Usage

1. Clone or download this repository.

2. Make the script executable:

chmod +x add_submodule.sh

3. Run the script with the submodule repository link and the target location within your repository:

./add_submodule.sh <submodule-link> <location>

Example:

./add_submodule.sh https://github.com/username/repo.git content/posts

This command adds the submodule repo into the content/posts/repo directory, creates a new branch named repo, commits the changes, pushes the branch, and opens a pull request against the main branch.

Future Work / Roadmap

• Support customizing the base branch for pull requests.
• Add error handling for GitHub CLI failures.
• Support adding multiple submodules in a single run.
• Add options for customizing commit messages and pull request descriptions.
• Provide more detailed logging and a verbose mode.

Note: This script assumes you have Git and GitHub CLI configured and authenticated.
