Study Notes
Git
- Git is a distributed version control system. It tracks file and folder changes over time, enabling team collaboration on projects.
- Designed primarily for code, but usable with any file type.
- Git replicates the repository history on each developer's machine rather than storing the full history on each.
- Core concepts:
- Commits: Record of modifications.
- Branches: Separate lines of development.
- Staging Area: Temporary хранилище for changes pre-commit.
- Working Directory: Files as they exist on the computer.
- Key commands:
-
git init: Initializes a new Git repository. -
git add <file>: Adds a file to the staging area. -
git commit -m "Description": Saves repository changes with a message. -
git branch: Lists all branches. -
git checkout <branch>: Switches to a different branch. -
git merge <branch>: Merges modifications from one branch to another. -
git push: Uploads local commits to the remote repository. -
git pull: Downloads remote repository changes to the local repository. -
git clone: Creates a local copy of a remote repository. -
git status: Displays the state of the working directory, staging area, and repository. -
git log: Shows commit history. -
git reset: Enables reversing changes between commits.
-
GitHub
- GitHub is a web-based platform for hosting Git repositories.
- Facilitates version control, collaboration, and project management.
- Predominantly used for software development but can apply to other projects that benefit from collaborative code management.
- Features:
- Online repository storage.
- Collaboration tools (e.g., issue tracking, pull requests).
- Access control to manage user permissions for repositories.
- Issue tracking supports problem reporting/resolution throughout development.
- Code review via pull requests strengthens quality control.
- Code hosting: GitHub directly hosts and allows interaction with the code.
- Relation to Git: GitHub acts as a remote repository for Git. Local Git repository changes are pushed and pulled to/from GitHub for collaborative development.
- GitHub workflows:
- Feature branches for new development.
- Pull requests for code review.
- Issues for managing tasks/bugs.
- Use Cases
- Open-source projects
- Team projects
- Individual project management
- Key benefits:
- Collaborative development
- Version control
- Code review
- Issue tracking
- Project management
- Accessible repositories through the web interface
