This assignment is not for a grade, but it's critical that you complete it on-time and understand the steps in the workflow you will be using for all assignments. If you run into troubles, please reach out on Ed or come by office hours!
Your goal for this assignment is two-fold:
- Walk through and understand the git workflow we use in this course
- Practice with your tools and refresh on background concepts
This assignment will give you practice with the standard tasks of getting starter code, editing files, committing changes, and submitting your work.
Have our Git Workflow Guide open in another browser tab. You will be following along with the section "Assignment Workflow" of the guide.
0. Choose your editor and configure for use with git
In Lab 0, we asked you to explore text editors like vim and emacs. You will be making heavy use of your chosen editor, so now is a good time to invest in becoming comfortable and efficient with it. This can be in the form of watching tutorial videos, reading manuals, bringing questions to OH, sharing tips with each other, and practicing on your own.
Some git commands automatically open a text editor on your behalf. If you have not set an editor in your git config, it uses a default choice. Which editor does git use as its default? Is this your preferred editor? If it is not, you can configure git to use the editor you prefer with the following command:
$ git config --global core.editor [NAME-OF-YOUR-PREFERRED-EDITOR]
1. Pull starter code
To get the starter files, follow the instructions "Pull assignment starter code" in the Git Workflow Guide.
Pulling the starter code adds a new subfolder named
assign0 to your
This folder contain the starter files for the assignment.
2. Answer background questions
assign0 subfolder, find the file named
background.txt and open it in your editor.
Add answers to the following questions. Make sure each your response is clearly labeled (i.e. we know what question it corresponds to) and reasonably organized.
Tip If you're stuck on any of the questions, take a look at the guides section of the course website, post on Ed, or start reading some articles online!
What is the result of performing a bitwise OR of the following two hexadecimal numbers (include the result in decimal):
0x0f OR 0xff. Now left shift that number by 24; what is the result in hexadecimal? Assume numbers are 32-bit.
How many milliamperes of current will flow through a 1.5K resistor connected to 3V on one end and 0V (Ground) on the other end?
Find a file in the directory
/etcon your computer; tell us the name of the file and the number of bytes contained in that file. How many files and directories are contained in the first level of directory
/etc? Include the commands you used to answer these questions.
Change directory to your
cs107e.github.iorepo and find the folder named
cs107e. What is the absolute path to this folder? What is the relative path using the CS107E environment variable you created during your environment setup? Remember this folder location! Inside the
cs107ethere is an
includefolder where all your assignment header files are located. (You can find more information on the filesystem in our unix guide).
What editor do you plan on using? What is your plan on learning how to best use your editor? (i.e. for people using vim, you can run the
vimtutorcommand from your terminal). . Tell us a bit about how you customized your editor! Confirm you have configured git to use your chosen editor.
In git speak, what is a "commit"? What is a "branch"? If you're unsure, refer to our git guide.
Save your edits to
background.txt and exit your editor.
3. Commit your changes locally and push to remote
Follow the instructions in "Assignment commit" of the Git Workflow Guide to
git commit a local snapshot, followed by
git push to synch those changes to your remote repo.
After you do this, both the local and repo repositories should be up to date. Browse the
dev branch of your remote repo on GitHub to confirm it is in sync.
4. Make submit tag
Apply the tag
assign0-submit to indicate these files are the ones to grade. Follow the instructions in the section "Assignment Tags"
in Git Workflow Guide to create and push a tag.
Browse your remote repo on GitHub and confirm that your new tag is listed.
5. Open pull request
To indicate that your submission is ready for grading, you must have an open pull request. Follow the instructions in the section "Assignment Pull Request" in the Git Workflow Guide.
Confirm your submission using the "Assignment checklist" section of the Git Workflow Guide Congrats! (but wait, there is more, see below…)
6. Add photo file and edit README with your info
What's missing? A wonderful CS107E tradition is creating a Wall of Fame with all of your and the teaching team's pictures and fun facts. We want to include you on our wall!
Find a photo of yourself that you would like to share. Copy this photo file into your
README.md file in the
assign0 folder to include the following information:
- Your preferred name and pronouns
- Your hometown
- A fun fact about you
Add both the photo file and README.md to the staging index. Commit and push to your remote repo.
7. Move submit tag
To indicate this updated commit should replace your previous submission, move the submit tag. Read the section "Assignment Tags" in the Git Workflow Guide for instructions on how to move a tag.
Browse your remote repo on GitHub and confirm that your submit tag is placed on the commit which contains the correct content for all three files (
README.md, and your photo file).
Congraulations, you have successfully navigated the full assignment workflow and are ready for further adventures to come!
- pull starter files
- edit files
- add and commit changes
- push to remote
- make submit tag
- open pull request
- update submission (if needed)
