Assignment 5 - Simple Git

Practicing basic Git commands

Objectives

  • Practice the basic Git commands: add and commit and, if necessary, reset
  • Navigate to a remote GitHub repository and push code to it.

Setup

  1. You must have completed both Lab: Git and GitHub setup and Lab: GitHub CLI setup prior to starting this assignment.

  2. Click this link: https://classroom.github.com/a/YpAD2CPJ

  3. Select your name on the “Join the classroom” page and continue.

  4. Select “Accept this assignment” on the next page. You will see a confirmation screen similar to the one below. Refresh the page if you don’t see it.

  5. Click on the link to your assignment repository. You will see a GitHub remote repository containing a README.md file:

    starting point of the repo for the assignment

  6. Open a Terminal open with your seng-201/ as the working directory. Run the commands below separately, replacing YOUR_REPOSITORY_URL with the URL of your assignment repository from the previous step.

    git clone YOUR_REPOSITORY_URL  # copy the code from GitHub to a new local repostiory

  7. In the Terminal, type cd YOUR_NEW_DIRECTORY to change into the project directory. It will be something like cd git-calc-LASTNAME

  8. Run the command git checkout -b more-options

This will create a new subdirectory named git-calc-YOUR_NAME that is a “clone” of a Git repository I created. The checkout -b command creates a new branch, which will be explained in the future.

Open the git-calc directory in your IDE. You will see two files, calc.py and .gitignore. You will do all your work in calc.py.

Instructions

Run calc.py and to try it out with the options. You are going to add to the functionality.

Follow the style in the code. Do not worry about our design rules, unit testing, input validation, or error handling.

  1. Create a separate commit with a brief, meaningful message for each option below. You must have at least two new commits to the more-options branch:
    1. Add a “power” option to raise one number to the power of another. Stage and commit it.
    2. Add a “logarithm” option that computes the log(x, base). Import the standard math library and use the log() function.
    3. The options must be incorporated into the user menu.
  2. All pre-existing options must continue to work, including “Quit”.
  3. Run the command git push to send your completed code to the remote (GitHub).
    • Verify that your changes are in GitHub by visiting your remote repository’s web URL and changing the main dropdown to say more-options.

Rubric

Partial credit is not awarded for these items: all or nothing.

  • (5 pts) Version history (git log) of submission shows a minimum of two new commits (in addition to my initial commit) with are meaningful, concise, and accurate. Commit messages are short summaries of the changes.
  • (5 pts) Your remote repo’s version history show that you contributes a minimum of two versions on the more-options branch.
  • (5 pts) All options (original features + your additions) correctly work in the final commit.

Submission due April 13

Your code is pushed to your GitHub repository.
