Review Code With Copilot

Python is one of the languages Copilot supports and being good at

How to use Copilot Chat for code reviews

1. Open the Chat window.

Type '/help', and you see a list of available commands:

• /tests - Generate unit tests
• /simplify - Simplify the code
• /fix - Fix problems and compile errors
• /explain - Explain how the code works
• /doc - Document the current selection of code
• /feedback - Steps to provide feedback

Click /explain

• Time-efficient
• Easier to find bugs
• Acting as a senior assistant
• Validates and double-checks your own analysis in code reviews

Without Copilot

• Requires context switching
• Mentally draining

Code reviews were more actionable and completed 15% faster with GitHub Copilot Chat.

Using Copilot Chat for Codebase Analysis

Context

• #selection - The current selection in the active editor
• #editor - The visible source code in the active editor
• #terminalLastCommand - The active terminal's lst run command
• #terminalSelection - The active terminal's selection
• #file - choosing file in the workspace

Improving prompt

Click a button to enable copilot to generate commit messages in VSCode source control button

• Enhanced productivity
• Particular helpful for bigger pull requests

Pull request summerization

• GitHub Copilot Enterprise version has a Summary button in each Creating Pull Request
• This featuer only works with GitHub Enterprise accounts

How Copilot Works

• Copilot takes into account the context of your code
• If no function prototype, it will just output something based on its training data
  • Prompt engineering give large language models extra context for their operation, to get the best output.
  • Copilot is based on ChatGPT 4
  • Course Prompt Engineering for Developers with Google Gemini

Write comments, Copilot will generate code, press tab to accept it.

Examples:

1. Write a funciton to calculat the average ticket price for a given event
2. Implement the function calculate_average_price that takesa a list of prices as input and returns the average price as a floating-point number

Code Refactoring with Copilot

1. Automatically adding unit tests with Copilot

   • Writing tests is time consuming
   • Unit tests must be maintainable

   How to do it?

   Select the code that needs unit test code. Click * buttion, enter /tests in the prompt window. Click Accept to generate a new file.

2. Solve furthur code issues

3. Find bugs with Copilot

   • Select the code, use /explain command

4. Document Generation

   • Select the code, use /doc command

GitHub Fundamentals (Pluralsight)

1. Overview of GitHub and Git

Concepts of Git

What is Git?

• Popular source control system
• Distributed system
• Free and open-source

Why use Git?

• Fast
• Disconnected (local repository)
• powerful yet easy to use
• Branching
• Pull requests (enabling colaborating)

But ...Why not Git?

• Different
• Learning curve
• Tools (it really shines when using commandline)
• Binary files

What is GitHub?

• Hosting service based on Git
• More than just source control for your code
• Free and paid options

Get your machine ready

• Git-scm.com

• An editor (VS Code)

• GitHub account

  Inside MINGW64

  git config --global user.name "your name"
  git config --global user.email "your email address"
  git config --edit --global
  

  Change git default editor

  git config --global core.editor "code --wait --new-window"
  

The 3 States of Git

• Commited
• Modified
• Staged

These states are still local

Working directory

Staging area (waiting to be commited) .git rep

Remote repo GitHub (The fourth area where code can be stored)

Workin with Git

• Command line (CLI)
  • git
  • git config
  • git init
  • git clone
  • git add
  • git commit
• GUI (some commands are unavailable)

Demo

mkdir "d:\code\pluralsight"
cd "d:\code\pluralsight"
git init
ls -la
git status
code readme.md
git add readme.md
git commit readme.md -m "with comment"
git add .
git log
git commit -am "new files message"

Understanding GitHub

• Project management
• Pull requests

Beyond the Basics

2. Getting Started with GitHub

Understanding GitHub

• Hosting service for Git
• Git and a lot of extras
• Social aspect of coding
• Part of Microsoft since 2018 (7.5 Billion dollars) (2007/2008 GitHub founded) (2022 55M users)

GitHub's Main Features
