Topics
Code anywhere and everywhere with git
What is git?
- Git is a version control system (VCS). A VCS allows you to keep track of changes in a file (or groups of files) over time
- Git allows you to store code on different computers and keep all these different copies in sync
Why are we learning git in this class?
- Collaborate
- Share code ownership
- Work on larger projects
- Provide feedback on work in progress
- Learn professional software development tools
Git concepts
- repo (short for repository): a place where all your code and its history is stored
-
remote repo: The repo created on github.com. You can access a remote repo via a browser (we’ll explore other ways later)
- In class demo:
- creating a repo on github.com
- adding collaborators to the repo
- adding files to the repo
- Updating files in a remote repo using a web browser
- Viewing the version history
- cloning a repo: Once you have created a repo, you (and your collaborators) can copy (or clone) it on different computers. Each instance is now a local repo, because it exists on your (local) computer rather than the web.
- Using git command line tools, we can sync up different repos. This means multiple collaborators can work on the same code on different machines.
