This is a quick summary of the "technical" steps we've followed so far:
Fork the Github Repository
You'll be given a repository from our organization (highlighted in the picture below). Use the Fork button to create your own "copy".
After that, the repo will be copied in your own Github profile:
Get your Clone URL
This is really important. We'll use this URL in the next step. In your fork, click on the Clone or download green button and Copy the "Clone URL" as shown below. Make sure you select HTTPS. A valid clone URL looks something like this:
https://github.com/santiagobasulto/itp-w1-basic-calculator.git (note the
.git at the end).
Create the Cloud9 Workspace
Go to https://ide.c9.io and click on the + Create new Workspace button. Put a meaningful name, mark it as Public, select the "Python" template and more importantly, use the Clone URL (retrieved before) to clone from your Github fork.
Getting familiarized with Cloud9
Explore your C9 workspace. At the left side you have the file-tree navigation view, at the bottom the terminal and in the center the editor.
Create a virtualenv
In the C9 terminal, use the
mkvirtualenv command to create a virtual environment. Choose a friendly name that's easy to remember. Don't include spaces or quotes. Virtual environments are a Python standard. You can read more here.
Virtualenvs need to be "activated" in order to work. When a virtualenv is active, you'll see the name at the left side of your prompt surrounded by parentheses:
Virtualenv commmand list:
mkvirtualenv $NAME: Creates a NEW virtualenv named $NAME
deactivate: Deactivates the current virtualenv
workon $NAME: Activates the virtualenv $NAME.
Install Python dependencies/requirements
In the terminal, run
pip install -r dev-requirements.txt. IMPORTANT! Make sure your virtualenv is active!.
Pip is the standard dependency manager for Python and a widely used tool. Make sure you get familiar with it: https://pip.pypa.io/en/stable/
Run your code and tests!
Now that everything is installed, we can start running our code and tests. You'll use the command
make for this. Here are a few examples:
make test: Run all your tests
make run: Run code in main.py (code under the
if __name__ == '__main__':block)
Pushing your changes to Github
Once you've completed the project you'll want to push your changes to Github and submit your Pull Request. Git is a key tool in Software Development. We seriously encourage you to get familiar with Git. This is a good start point: https://try.github.io. Even though Git is a powerful and complex tool, what we need to push our code are just a few commands.
Review the changes made
git status will tell you what files you've changed:
git diff will show you the changes made in those files.
Create a commit
Start by adding your files to the index with the
git add command. After you add the files,
git status will show them in green, as "added":
Now it's time to create the commit using the
git commit -m command. After the
-m flag you need to provide a human-friendly message specifying what changes you've made:
If you run
git status again, you'll see that there are no more changes (as you've already committed the previous).
Push your code
Just run the command
git push and your changes will be pushed to your Fork on GitHub.
