To run this application use python3 main.py. You will need to first install Python which can be done online at https://www.python.org/downloads/ and you will need to install any necessary dependencies such as Flask using pip install Flask on the commandline after installing Python.

Exercises

There are some bugs in this code and features we need to add. To make sure you have correctly installed Flask and cloned this repo, when you run the application and open the link in your browser (http://127.0.0.1:5000/) you should see a welcome page that says "Welcome to COMP3900".

Setting up the repo

  • You will be cloning my repo but working on your own. To do this, you must first setup your own personal Github account and create a PRIVATE repo called comp3900_git_primer.
  • Next, clone my repo from Github at https://github.com/Dhruv-A/comp3900_git_primer and then cd comp3900_git_primer to go into the repo.
  • We are going to transfer this to your Github repo. To do this, use the command git remote set-url origin git@github.com:GITHUB_USERNAME/REPO_NAME.git replacing GITHUB_USERNAME and REPO_NAME with the ones for the repo you created.
  • Now run git push and you can get started with the exercise.
  1. We need to make a small modification as this page should include COMP9900 as well. Add COMP9900 to the greeting message in a new branch. To create a new branch and switch to it you can use git checkout -b welcome_message_renaming. Then make the necessary changes and add them using git add <filename> and commit them with a meaningful commit message using git commit -m <write your commit message here>.
  2. You will need to show your tutor you made this change so DO NOT merge this branch into main or delete it. However, you should push it to the remote branch using git push.
  3. We are going to create a new branch based off the one we are currently on to fix some other issues. Use git checkout -b welcome_and_calculator_fix to switch to a new branch where we will debug the calculator. If you try using the calculator right now, you will see that it does not add the numbers but instead multiplies them.
  4. Fix this issue and then commit your change to git. This time, we want to merge a branch called incorrect_branch_name into this branch (welcome_and_calculator_fix) using git merge incorrect_branch_name. Note: there is already a remote branch with this name that you are trying to merge into. You will need to work out exactly how to merge it with that. However, when you try to merge it in, you will encounter a merge conflict as there are already changes in the other branch. Remove the other branch's changes and replace them with your fix to the COMP[39]900 welcome message.
  5. Once the code has been merged, push it to Github (the remote version of your branch) using git push. If it tells you your branch does not have a remote version, then use the suggested command it gives you.
  6. Now, on Github it will give you a message saying there were recent changes to a branch and ask you if you want to submit a pull request. Create the pull request but DO NOT accept it. You will need to show your tutor the unapproved pull request.
