CopilotDev.NET

CopilotDev.NET

Unofficial C# developer API for Github Copilot.

Terms of Service and Considerations

• This implementation has been written from scratch and does not contain any third party code. The code is fully licenced under MIT by me.
• Calling the endpoints of Github Copilot is governed by the terms of service of Github Copilot. Keep Fair Use in mind.
• The implementation may break at any given time. The called HTTP endpoints are not part of a public API.
• This API is not intended to be used for any production cases because it may break any moment and would probably violate the terms of service of Github Copilot.

Usage

Nuget.org

Install-Package CopilotDev.NET.Api

Take a look into CopilotDev.NET.ConApp/Program.cs. Clone the repository and try to run it.

// Build Api in your main class
var httpClient = new HttpClient();
var copilotConfiguration = new CopilotConfiguration();
// Should be where your application stores files. You can also implement CopilotDev.NET.Api.Contract.IDataStore instead to store it in your own storage (e.g. database).
var dataStore = new FileDataStore(".\mytokens.json"); 
var copilotAuthentication = new CopilotAuthentication(copilotConfiguration, dataStore, httpClient);
copilotAuthentication.OnEnterDeviceCode += data =>
{
     // You may open a browser window here instead.
     Console.WriteLine($"Open URL {data.Url} to enter the device code: {data.UserCode}");
};

// Use this ICopilotApi instance in your application e.g. Dependency Injection of ICopilotApi
ICopilotApi copilotApi = new CopilotApi(copilotConfiguration, copilotAuthentication, httpClient);

Example 1

var completions1 = await copilotApi.GetStringCompletionsAsync("public class Em");
Console.WriteLine("Completions for 'public class Em':");
Console.WriteLine(string.Join("",completions1));
Console.WriteLine("---");

Example 2

var completions2 = await copilotApi.GetCompletionsAsync(new CopilotParameters
{
    // Q: How do I get specific programming language suggestions? A: Unknown, however you can always add more context to your prompt like 'in Java'.
      Prompt = "/**  " +
           "Returns the next 5 Fibonacci numbers in Java. " +
           "@return Array of integer." +
            "**/",
       MaxTokens = 200
});
Console.WriteLine("Completions for a method description:");
Console.WriteLine(string.Join("", completions2.Select(e => e.Choices[0].Text)));
