What is GitHub Copilot?

  • GitHub Copilot is an AI pair programmer that provides autocomplete-style suggestions as you code[1][4].
  • It is powered by a generative AI model developed by GitHub, OpenAI, and Microsoft, trained on a vast corpus of publicly available code[1][4].
  • Copilot supports a wide range of programming languages, with the quality of suggestions depending on the volume and diversity of training data for each language[4].
  • It is available as an extension for various IDEs and editors like Visual Studio Code, JetBrains IDEs, Neovim, etc.[1][4]

Visual Studio Code: Introducing GitHub Copilot

Summary

The video introduces GitHub Copilot, a tool designed to enhance the productivity and speed of developers by assisting with coding through AI-driven suggestions, known as "Ghost Text". Once GitHub Copilot is installed and logged in, it's automatically activated. Developers can simply code as usual and Copilot will provide real-time coding suggestions.

Key features of GitHub Copilot include:

  • Ghost Text: Automatically suggests code snippets as you type. You can accept suggestions by pressing Tab, or use Control or Command keys with the right arrow to accept partial suggestions. Press Escape to dismiss suggestions.
  • Inline Chat: Allows for real-time conversation with the AI to iterate on code directly in the editor, which can be triggered with Control or Command + I. Changes are shown in a diff view before acceptance.
  • Dedicated Chat Area: Found in the sidebar, similar to other AI chat tools, useful for brainstorming and solving complex coding issues.
  • Error Resolution and Suggestions: GitHub Copilot appears in the light bulb or quick suggestion menu to offer explanations and fixes for coding errors.

Commands for GitHub Copilot

  • Activate Ghost Text: Simply start coding, and Copilot will offer suggestions.
  • Accept Ghost Text: Press Tab to accept full suggestions or use Control/Command + Right Arrow for partial acceptance.
  • Dismiss Suggestions: Press Escape to dismiss the current suggestion.
  • Inline Chat Activation: Use Control/Command + I to start an inline chat with GitHub Copilot for direct code modification suggestions.
  • Toggle Copilot: Click on the GitHub Copilot icon in the status bar to enable or disable Copilot for specific files or languages.
  • View Alternatives: Press Control/Command + Enter to see alternative suggestions in a sidebar panel.

GitHub Copilot is designed to significantly streamline the coding process, making it easier for developers to write code efficiently and with fewer errors.

How does GitHub Copilot work?

1. Analyzing context:

  • Copilot analyzes the context in the file you are editing, as well as related files[4].
  • It examines the code structure around your cursor position, including the current line and relevant function/class scope[10].

2. Generating suggestions:

  • Based on the analyzed context, Copilot uses the AI model to generate code suggestions[1].
  • Suggestions can be a completion of the current line, a whole new block of code, or even entire functions[4].
  • Copilot makes probabilistic determinations to generate suggestions, rather than copying and pasting from the training data[3].

3. Accepting suggestions:

  • The generated suggestions appear inline in your code editor.
  • You can accept the suggestion entirely or partially, or ignore it and keep typing[4].

4. Iterative improvements:

  • As you continue coding, Copilot learns from your coding patterns and style.
  • It adapts suggestions to match your project's context and coding conventions[1].

Additional features and use cases

  • Chat interface: Copilot also provides a chat feature where you can ask questions, get explanations for code, and receive guidance on coding tasks[11].
  • Generating documentation: Copilot can help write documentation comments for your code[8].
  • Code refactoring: It can suggest refactorings and improvements to existing code[11].
  • Debugging assistance: Copilot can provide suggestions for fixing bugs and errors in your code[11].

GitHub Copilot aims to enhance developer productivity by reducing the time spent on repetitive coding tasks and providing intelligent code suggestions. However, it's important to review and test the generated code for accuracy and reliability, as Copilot's suggestions may not always be perfect or bug-free[4].
