What is Git?
Git is a distributed version control system (DVCS) that allows developers to track changes to their source code over time, collaborate with others, and manage code repositories. It was created by Linus Torvalds in 2005 for the development of the Linux kernel.
Key Git Concepts:
- Repository: A Git repository is a directory where all the project files and their revision history are stored.
- Commit: A commit is a snapshot of the changes made to the files in the repository at a particular point in time.
- Branch: Branches allow developers to work on different features or bug fixes independently, without affecting the main codebase.
- Merge: Merging is the process of integrating changes from one branch into another.
Why is Git Useful for IBM i Systems?
Improved Version Control
Git provides a more robust and flexible version control system compared to traditional IBM i source control tools like PDM and RCS.
Developers can easily track changes, revert to previous versions, and collaborate on code without the limitations of IBM i-specific tools.
Distributed Development
Git's distributed nature allows developers working on IBM i applications to work independently, commit changes, and synchronize their work with a central repository
This facilitates remote and distributed development, which is increasingly important in modern software teams.
Branching and Merging
Git's branching and merging capabilities make it easier to manage complex development workflows, such as feature branches, bug fixes, and releases.
Developers can create and switch between branches, merge changes, and resolve conflicts, all while maintaining a clear and organized codebase.
Integration with Modern Tools
Git integrates well with a wide range of modern development tools and platforms, such as GitHub, GitLab, and various Continuous Integration/Continuous Deployment (CI/CD) tools.
This allows IBM i developers to leverage the same tools and workflows used by the broader software development community.
Collaboration and Code Sharing
Git makes it easier for IBM i developers to collaborate on code, share changes, and review each other's work, even if they are geographically distributed.
This can lead to improved code quality, knowledge sharing, and overall team productivity.
In summary, Git provides IBM i developers with a powerful and flexible version control system that can significantly improve their development workflows, collaboration, and integration with modern software development practices.
