Requirements

Copilot extension requires some additional tools to be installed:

• Copilot Language Server

Install Copilot Language Server

npm install @github/copilot-language-server

Check installation

$ copilot-language-server --version
1.302.0

Configuration

Once Copilot Language Server is installed we need to set the correct path in extension settings

Open Extensions > Extension Library > Copilot then select Copilot's Settings tab.

In the Copilot Language Server path paste the copilot-language-server path.

Path can be found using which command

$ which copilot-language-server
/Users/besya/.local/share/mise/installs/node/23.11.0/bin/copilot-language-server

1. Go to Extensions > Copilot > Sign In
2. Notification should appear with the code
3. Copy the code and click "Sign in with Github"
4. Switch to your browser and you should see the Github's Device Activation page
5. Click "Continue"
6. Paste the code you copied earlier
7. Click "Continue"
8. Click "Authorize Github Copilot Plugin"
9. You should see the page with "Congratulations, you're all set!" message
10. Close this page and switch back to Nova
11. Wait a few seconds and the Notification should appear with the "Authorized" message
12. Congratulations. Now you are able to use Copilot

If you have issues related to Sign In check this steps first:

Completions

Default shortcut for inline completion command is ^" (control-shift-')
The completion provided by copilot-language-server should appear next to your cursor position and autoselected.

Custom shortcut

Changing the default keyboard shortcut to a custom one is very easy:
1. Open Nova Settings (command+,)
2. Select "Key Bindings"
3. Enter "inline completion" in the Filter input field
4. Select the "Inline completion (Copilot)" row
5. Double-click the ^" shortcut and enter your own

Experimental feature

There is a another option to use inline completion and it's a completion by typing. This invocation happens on TextEditor.onDidStopChanging.

This mode can be enabled in Extensions > Extension Library > Copilot > Settings by enabling the Enable inline completions on typing checkbox.

WARNING: This is an experimental feature, so be careful not to lose or break your code by using it.
