Git and Github

Git is an open-source version control tool, created in 2005.

GitHub is a company that creates tools to use git founded in 2008.

We use the terminal to create our git in the folder:

//the touch command doesn't work in windows

mkdir your_folder        //to create a folder
cd your_folder           //to move into a folder
cd ..                    //to exit a folder
git init                 //to start our git work

Any code of file will be added to the staging environment, we can check with git status:

Utracked changes

Not yet in the staging

Git add. changes

not yet commited but in staging

git commit -m "changes"

commited changes with message

We can push local code to a GitHub repository:

git remote add origin __github repository url__
git push -u origin main

We use Branches to test changes we can merge to the main code:

git checkout -b new_branch       //will create and move us to the new branch
git branch                       //to check which branch we are
git checkout main/other_branch   //to move branch, any changes will need to be commit
git restore .                    //will delete any un-committed changes

And even branches can be pushed to a GitHub repository.

When other branches are pushed a pull request opens, to check proposed changes and to solve code conflicts, a new repository branch will also open and can receive pushes even without a solved pull request.

We can then use git pull to set the repository code into our local machine.

more git commands:

git clone __url__                //will copy code/files from GitHub URL
git rm index.html                //will remove files if those are committed

git merge __branch to merge with the current one__
//It won't delete the merging branch, and we still need to commit it after merge
