Visual Code

• Summarized some basic features
• Talked a little about MarkDown

Github operations

Cloning

This clones the repo and the 'main' branch to a directory called 'Project0-OOP'

git clone git@github.com:bellag10/Project0-OOP.git

This clones the repo and 'main' branch to directory called 'MyProject'

git clone git@github.com:bellag10/Project0-OOP.git MyProject

This clones the repo and a branch called 'BGProject' into directory BGProject

git clone -b BGProject git@github.com:bellag10/Project0-OOP.git BGProject

Be sure to change into the cloned repo directory. When your doing git commands, be sure to be at the top directory of the clone.

cd BGProject

Making changes directly to the main branch

Add the files that need to be committed to main

This shows three different ways to add files. One, multiple in different directories, and all contents in a specific directory, respectively

git add src/main/app.py
git add src/datastore/dbdriver.py data/konkkonk.csv
git add docs/

Note: There's a way to tell git to ignore certain files using .gitignore file which just is a text file with a list of file paths.

This shows how to remove files. Don't use shell command rm. Use the git rm. It will delete the files and mark them as deleted in git.

git rm src/main/crud.py

Remove an entire directory using the recursive flag

git rm -r junk/

This shows how to move files

git mv src/main/gigi.py src/data/store/gigi.py

Check the state your your git ops. This will show you what's not tracked, what's tracked, and new files. It will also show you what branch you are in.

git status

This shows how to reset all of your changes to start again. Check the status afterwards.

git reset
git status

Commit your changes and a comment using -m and append the command like so

git commit -m 'Making changes for issue 1223'

Push your changes to main

git push

Making changes directly to specific branch for a pull request (most common use case)

Change directory into cloned repository and run git command to 'checkout' or create a new branch called 'Changes-for-issue1223'

cd BGProject
git checkout -b 'Changes-for-issue1223'

Now add and commit your files

git add src/datastore/dbdriver.py data/konkkonk.csv docs/
git status
...
git commit -m 'Making changes for issue 1223'

Now push to the files to the new branch. If you forget, use git status to see what branch you're on.

git push origin Changes-for-issue1223

Home work

• Create a new branch copy of datathon in the same repository
• Practice create a mock PR or an actual change to our copy of datathon.

Next time:

• More practice of command line
