Git is a distributed version control system that allows users to track changes to files over time. It keeps a record of the history of changes (revisions) to files in a repository. Each user has their own local copy of the source code repository. Basic Git operations include cloning a remote repository, pulling updates, pushing local changes, creating and switching branches, and merging branches. The document recommends a feature-based workflow for collaborating that involves regularly pulling updates, rebasing local branches, committing changes, merging to master, and pushing changes.
Git: A Getting Started Presentation
- 1. Git: A Getting Started presentation by: Nap Ramirez email: napramirez@gmail.com
- 2. INTRODUCTION What is Git? Git is a distributed version control system (DVCS). Version control systems keep track of the changes in files and directories over time. ● records the history of data ● acts like a time machine of data
- 3. INTRODUCTION Architecture Git is a distributed system, everyone has their own copy of the source codes.
- 4. GETTING USED TO... Terminology Repository ● a storage of the history of changes of the tracked files, hidden from the user Working Copy ● the set of tracked files Revision ● a specific state of data recorded in the history
- 5. GETTING USED TO... Terminology (continued) Branch ● a separate line of history of the tracked files deviating from the origin or another branch Tag ● a reference to a specific state of a branch
- 6. LEARNING... Basic Operations Clone Remote Repository (git clone) ● acquire a copy of a repository ● `$ git clone git@git.mydomain.com:myproject.git` Pull Updates From Repository (git pull) ● get updates from another repository and apply those into your repository ● `$ git pull origin master` Pushing Changes To Repository (git push) ● send changes in your repository to another repository ● `$ git push remote master`
- 7. LEARNING... Basic Operations (continued) Create Branches (git branch <name>) ● creates a local branch based from the active branch ● `$ git branch feature1` Switch Branch (git checkout <name>) ● switches active branch to any existing one ● `$ git checkout -b feature1` Merging Branches (git merge) ● apply changes from specified branch ● `$ git merge feature1` Perform/Apply Changes (git commit, git add) ● mark changes in history of active branch ● `$ git commit -am “changed the button label”` ● `$ git add README.txt`
- 8. LEARNING... Feature-based Workflow 1. Pull from remote master into local master (in master, git pull) 2. Rebase local branch to changes from master (in local branch, git rebase master) 3. Perform changes, then commit to local branch (in local branch, git commit) 4. Merge to local master (in local master, git merge <local-branch-name>) 5. Push changes (in local master, git push)
- 9. Let's put it to the test! Exercise Practice the Feature-based Workflow. Create tags, use gitk and the stash.
- 10. THE END... Thanks! Please mail me your feedback! ---------------------------- Nap Ramirez napramirez@gmail.com
