  • 1. Git Workshop What is an “Estimate” ? Wildan Maulana [email_address] http://workshop.openthinklabs.com #1
  • 2. About Version Control Local Version Control Systems Centralized Version Control Systems
  • 3. About Version Control Distributed Version Control Systems
  • 4. A Short History of Git Linux kernel maintenance 1991–2002 Changes to the software were passed around as patches and archived files 2002 The Linux kernel project began using a proprietary DVCS system called BitKeeper. 2005 The relationship between the community that developed the Linux kernel and the commercial company that developed BitKeeper broke down, and the tool’s free-of-charge status was revoked 2005 Git birth - Speed - Simple design - Strong support for non-linear development (thousands of parallel branches) - Fully distributed - Able to handle large projects like the Linux kernel efficiently (speed and data size)
  • 5. Git Basics Snapshots, Not Differences . Other systems tend to store data as changes to a base version of each file. Git stores data as snapshots of the project over time.
  • 6. Git Basics Nearly Every Operation Is Local
  • 7. Git Basics Git Has Integrity
  • 8. Git Basics Git Generally Only Adds Data
  • 9. Git Basics The Three States Working directory, staging area, and git directory.
  • 10. The Basic Git Workflow
    • You modify files in your working directory.
    • 11. You stage the files, adding snapshots of them to your staging area.
    • 12. You do a commit, which takes the files as they are in the staging area and stores that snapshot permanently to your Git directory.
  • 13. Installing Git
    • Installing from Source
    • 14. Installing on Linux
    • 15. Installing on Mac
    • 16. Installing on Windows
  • 17. First-Time Git Setup gitconfig
    • /etc/gitconfig file: Contains values for every user on the system and all their repositories. If you pass the option --system to git config, it reads and writes from this file specifically.
    • 18. ~/.gitconfig file: Specific to your user. You can make Git read and write to this file specifically by passing the --global option.
    • 19. config file in the git directory (that is, .git/config ) of whatever repository you’re currently using: Specific to that single repository. Each level overrides values in the previous level, so values in .git/config trump those in /etc/gitconfig .
  • 20. First-Time Git Setup Your Identity $ git config --global user.name “Ibnu Sina" $ git config --global user.email ibnusina@openthinklabs.com
  • 21. First-Time Git Setup Your Editor $ git config --global core.editor emacs
  • 22. First-Time Git Setup Your Diff Tool $ git config --global merge.tool vimdiff
  • 23. First-Time Git Setup Checking Your Settings $ git config --list http.proxy= user.email=ibnusina@openthinklabs.com user.name=Ibnu Sina core.editor=emacs merge.tool=vimdiff $ git config user.name Ibnu Sina
  • 24. First-Time Git Setup Getting Help $ git help <verb> $ git <verb> --help $ man git-<verb> $ git help config #git or #github channel on the Freenode IRC server (irc.freenode.net)
  • 25. Summary
    • You should have a basic understanding of what Git is and how it’s different from the CVCS you may have been using. You should also now have a working version of Git on your system that’s set up with your personal identity. It’s now time to learn some Git basics.
