4. version control with git
5. What is version control?
6. why git?
8. - A powerful easy to use DVCs - The most used VCSs in the world
9. history: Know exactly which files changed, who made those changes, and when those changes occured. backup: Ability to have different versions of the code in different places. collaboration: Collaborate easily with other people on the same codebase
10. workshop outline
11. my first git: repositories, staging, committing git good: branching, jumping around, merging git world: enter in the repository world git ideas: cool stuff to do with git open sourcing: the idea that it’s a changing.
12. $ terminal commands are typed with this font and color. before we begin...
13. don’t worry! there is always a cheat sheet!
14. my first git Create your shiny repo and your first commit.
15. what is a repository? A repository is like any other folder on your computer, it can contain any type of file and works in exactly the same way… Except: It has a hidden file named ".git" that stores the history of that folder
16. Local Repository? - The local repo is on your computer. - It has all the files and their commit history. - It enables full diffs, history review, and committing when offline.
17. Remote Repository? - The local repo on cloud in someone else computer. - You can host you remote repo on platforms like GitHub/GitLab/Bitbucket. - It enables all the things you can do with your local repo.
18. Let's take a look at
19. first, install git
20. Install Git for Linux If you’re on Fedora (or any closely-related RPM-based distribution, such as RHEL or CentOS), you can use dnf: If you’re on a Debian-based distribution, such as Ubuntu, try apt:
21. Install Git on MacOS There are several ways to install Git on a Mac. The easiest is probably to install the Xcode Command Line Tools.
22. Install Git on Windows Just go to:
23. second, start a new repository by $ git init <repository name>
24. what are commits? snapshots of the state (e.g. code) of your repository
25. commit your work by using $ git add . $ git commit -m “<details>”
26. more about commits Bc7fd9 “Add Oranges” a3ffde “Add apples” 9cd1ce “First commit, Add fruit.txt” Commits form a linked list structure which shows what you have done over time. Use git log to see your commit history.
27. staging changes Unstaged Changes Staged Changes Committed Changes git add git commit git reset <hash> git reset .
28. my first git: recap $ git init - converts a folder to a super smart git repository. $ git add - adds the files you want to be tracked to the staging area. $ git commit - creates a new snapshot of your repository at that point in time. $ git reset - Undo your commit or unstage your files. $ git log - View your commit history. $ git status - See the current status of your repository
29. Let's take a look at
30. git good branching, context switching, merging
31. Bc7fd9 “Add oranges” a3ffde “Add apples” 9cd1ce “First commit, Add fruit.txt” commits
32. working with branches $ git branch - see a list of all available branches. $ git branch <branchname> - create a new branch with the desired name, based on the current branch.
33. Bc7fd9 “Add oranges” a3ffde “Add apples” 9cd1ce “First commit, Add fruit.txt” master commits branches
34. working with HEAD $ git checkout <branch name> - Redirect HEAD to the desired branch
35. Bc7fd9 “Add oranges” a3ffde “Add apples” 9cd1ce “First commit, Add fruit.txt” master commits branches HEAD HEAD somebranch
36. merging = combining commits $ git merge <branch name> - creates a new commit that combines the last commit of the current HEAD branch with the last commit of the desired branch.
37. git good: recap... $ git branch - List all branches $ git branch <name> - creates a branch with that name $ git checkout <name> - jump to the branch with this name $ git merge --no-ff <name> - merge the branch with this name into the current one.
38. git world publishing, updating and downloading
39. Let's take a look at
40. downloading / updating Repos $ git clone <url> - downloads a copy of a remote git repository. $ git pull - performs a merge of what you have on your computer with what's on the server. $ git push - sends your version to the server.
41. git ideas a quick look at what other folks are doing on
