Supported extensions and languages

Code suggestions are available in the following editor extensions and for the following languages.

Supported editor extensions

To use code suggestions, use one of these editor extensions:

A GitLab Language Server is used in VS Code, Visual Studio, and Neovim. The Language Server supports faster iteration across more platforms. You can also configure it to support code suggestions in IDEs where GitLab doesn’t provide official support.

You can express interest in other IDE extension support in this issue.

Supported languages

Code suggestions are aware of common popular programming languages, concepts, and infrastructure-as-code interfaces, like Kubernetes Resource Model (KRM), Google Cloud CLI, and Terraform.

Code suggestions support these languages:

Locally, you can add more languages. For languages not listed in the table, code suggestions might not function as expected.

Manage languages for code suggestions

You can customize your coding experience in VS Code by enabling or disabling code suggestions for specific supported languages. You can do this by editing your settings.json file directly, or from the VS Code user interface:

1. In VS Code, open the extension settings for GitLab Workflow:
   1. On the top bar, go to Code > Settings > Extensions.
   2. Search for GitLab Workflow in the list, and select Manage ().
   3. Select Extension Settings.
2. In your User settings, find the section titled AI Assisted Code Suggestions: Enabled Supported Languages.
3. You will see a list of all supported languages with checkboxes next to each language.
4. To enable code suggestions for a language, ensure its checkbox is checked.
5. To disable code suggestions for a language, uncheck its checkbox.
6. Your changes are automatically saved and will take effect immediately.

When you disable code suggestions for a language, the Duo icon changes to show that suggestions are disabled for this language. On hover, it shows Code Suggestions are disabled for this language.

Add support for more languages

If your desired language doesn’t have code suggestions available by default, you can add support for your language locally.

Prerequisites:

• You have installed and enabled the GitLab Workflow extension for VS Code.
• You have completed the extension setup instructions, and authorized the extension to access your GitLab account.

To do this:
