Excluding content from GitHub Copilot

About content exclusions for Copilot

You can use content exclusions to configure Copilot to ignore certain files. When you exclude content from Copilot:

• Code completion will not be available in the affected files.
• The content in affected files will not inform code completion suggestions in other files.
• The content in affected files will not inform GitHub Copilot Chat's responses.

Who can configure content exclusion

Repository administrators and organization owners can configure content exclusion.

• Repositoryadministrator*innen können nur Inhalte für ihre eigenen Repositorys ausschließen. Das wirkt sich auf Copilot-Benutzer*innen aus, die in diesen Repositorys arbeiten.
• Organisationsbesitzer*innen können Inhalte für Benutzer*innen ausschließen, denen ein Copilot-Arbeitsplatz über ihre Organisation zugewiesen wurde.

Availability of content exclusions

Limitations of content exclusions

Es ist möglich, dass Copilot semantische Informationen aus einer ausgeschlossenen Datei verwenden kann, wenn die Informationen von der IDE in einer nicht ausgeschlossenen Datei bereitgestellt werden. Beispiele für solche Inhalte sind Typinformationen und Hover-Over-Definitionen für im Code verwendete Symbole.

Data sent to GitHub

After you configure content exclusion, the client (for example, the Copilot extension for VS Code) sends the current repository URL to the GitHub server so that the server can return the correct policy to the client. These URLs are not logged anywhere.

Configuring content exclusions for your repository

You can use your repository settings to specify content in your repository that GitHub Copilot should ignore.

1. Navigieren Sie auf GitHub zur Hauptseite des Repositorys.

2. Wähle unter dem Namen deines Repositorys die Option Einstellungen aus. Wenn die Registerkarte „Einstellungen“ nicht angezeigt wird, wähle im Dropdownmenü die Option Einstellungen aus.

   

3. In the "Code & automation" section of the side bar, click Copilot.

   If your repository inherits any exclusions from its parent organization, you'll see a gray box at the top of the page containing details of these exclusions. You cannot edit these settings.

4. In the box following "Paths to exclude in this repository," enter the paths to files from which Copilot should be excluded.

   Use the format: - "/PATH/TO/DIRECTORY/OR/FILE", with each path on a separate line. You can add comments by starting a line with #.

Example of paths specified in the repository settings

# Ignore the `/src/some-dir/kernel.rs` file in this repository.
- "/src/some-dir/kernel.rs"

# Ignore files called `secrets.json` anywhere in this repository.
- "secrets.json"

# Ignore all files whose names begin with `secret` anywhere in this repository.
- "secret*"

# Ignore files whose names end with `.cfg` anywhere in this repository.
- "*.cfg"

# Ignore all files in or below the `/scripts` directory of this repository.
- "/scripts/**"

- "/src/some-dir/kernel.rs"

- "secrets.json"

- "secret*"

- "*.cfg"

- "/scripts/**"

# Ignore the `/src/some-dir/kernel.rs` file in this repository.
- "/src/some-dir/kernel.rs"

# Ignore files called `secrets.json` anywhere in this repository.
- "secrets.json"

# Ignore all files whose names begin with `secret` anywhere in this repository.
- "secret*"

# Ignore files whose names end with `.cfg` anywhere in this repository.
- "*.cfg"

# Ignore all files in or below the `/scripts` directory of this repository.
- "/scripts/**"

Configuring content exclusions for your organization

You can use your organization settings to specify files that GitHub Copilot should ignore. The files can be within a Git repository or anywhere on the file system that is not under Git control.

1. Wählen Sie in der oberen rechten Ecke von GitHub Ihr Profilfoto aus, und klicken Sie dann auf Ihre Organisationen.

2. Klicke neben der Organisation auf Einstellungen.

3. In the left sidebar, click Copilot then click Content exclusion.

4. In the box following "Repositories and paths to exclude," enter the details of files from which Copilot should be excluded.

   To exclude files located anywhere (within a Git repository or elsewhere), enter "*": followed by the path to the file, or files, you want to exclude. If you want to specify multiple file path patterns, list each pattern on a separate line.

   To exclude files in a Git repository from Copilot, enter a reference to the repository on one line, followed by paths to locations within the repository, with each path on a separate line. Use the following format, replacing REPOSITORY-REFERENCE with a reference to the repository that contains the files you'd like to exclude:

   REPOSITORY-REFERENCE:
     - "/PATH/TO/DIRECTORY/OR/FILE"
     - "/PATH/TO/DIRECTORY/OR/FILE"
     - ...
   

   Repositories can be referenced using various protocols. You can use any of the following syntaxes for REPOSITORY-REFERENCE and Copilot will match them regardless of how the repository was cloned locally:

   http[s]://host.xz[:port]/path/to/repo.git/
   
   git://host.xz[:port]/path/to/repo.git/
   
   [user@]host.xz:path/to/repo.git/
   
   ssh://[user@]host.xz[:port]/path/to/repo.git/
   

   The user@ and :port parts of the REPOSITORY-REFERENCE are ignored in the calculation of which paths to ignore for a repository.

   For Azure DevOps, you can use the new (dev.azure.com) or old (visualstudio.com) host format when specifying REPOSITORY-REFERENCE, and Copilot will match them regardless of which host was used to clone the repository locally.

Testing changes to content exclusions

You can use your IDE to confirm that your changes to content exclusions are working as expected.

Propagate content exclusion changes to your IDE

After you add or change content exclusions, it can take up to 30 minutes to take effect in IDEs where the settings are already loaded. If you don't want to wait, you can manually reload the content exclusion settings using the following instructions.

• For JetBrains IDEs and Visual Studio, reload the content exclusion settings by closing and reopening the application.
• For Visual Studio Code, use the following steps to reload the content exclusion settings:
  1. Access the Command Palette. For example, by pressing Shift+Command+P (Mac) / Ctrl+Shift+P (Windows/Linux).
  2. Type: reload.
  3. Select Developer: Reload Window.
• For Vim/Neovim, content exclusions are automatically fetched from GitHub each time you open a file.

Test your content exclusions

There are a few different ways to test your content exclusions, depending on which IDE you're using.

1. Open a file that you expect to be affected by your content exclusions.
2. Use one or more of the following techniques to test if content is being excluded:
   • In JetBrains IDEs, Visual Studio, and Visual Studio Code, check the Copilot icon in the status bar. If a Copilot content exclusion applies to the file, the Copilot icon will have a diagonal line through it. Hover over the icon to see whether an organization or the parent repository disabled Copilot for the file.
   • In Vim/Neovim, begin typing in the file. If GitHub Copilot no longer provides inline suggestions as you type, the file is excluded.
   • You can also test content exclusions in Copilot Chat. Open the Copilot Chat window, and ask Copilot Chat a question about the excluded file. If your content is excluded successfully, Copilot will be unable to answer your question, and will explain that some files were excluded from the conversation due to content exclusion rules.
